V6 MR2! Any one done it? Let's get a discussion going on the topic. In particular I am interested in MKII, but we can talk MKI also.
Please don't post replys asking why we would consider such a thing since 2.0 turbo fours are capable of 400-something HP. Raw power #'s are not the point here.
Here is my brief list of engine candidates:
92-94 3VZE 3.0L Your basic iron block Camry motor
92-? 5VZE 3.4L Longer stroke version of the 3VZE for trucks mainly
96-up 1MZ 3.0L Alum. block Camry and Lexus motor. I believe late ones have variable valve timing.

Does anyone know if the 3VZE/5VZE would bolt on to the 5SFE tranny?

V6's from other manufacturers could be considered such as the new Maxima motor; the old Yamaha-Taurus SHO V6 (big intake plenums would be into the seat and trunk, but capable of big high-rpm power); the Mitsubishi 3000GT/Stealth V6 (hugh power capability and fairly compact, but twin turbos might cook things); the GM 92-96 3.4L 4-cam 60-deg V6 (very compact and 215hp, but it's American).

Eh, have you ever seen the engine bay of an MR2? Where would you fit the V6? The only one I could see fitting is the really little one out of a Mazda MX3, but they're pretty weak. Most of those engines you've mentioned, especially the 3KGT/Stealth engine are really really wide and don't stand a chance of fitting. It's not really a bad concept though as the extra torque and sound of the 6cyl would be nice, but it's not a likely option. Plus I imagine the added weight of the bigger block/heads/manifolds would really fuck up the weight distribution. Just my .02¢

Oh also forgot about the tranny. I'm not positive, but I'm pretty sure the trannies in those engines wouldn't work with the MR2 drivetrain layout.

I have done quite a bit of measuring on my '91 MR2 and I believe that there are some V6's out there that will fit but not by much. Some may require a little reworking of the sheetmetal for enough clearance (this is how you stuff a small block Chevy into a Porsche 914 which I've done).
The 3VZ should fit without a whole of clearancing and should end up with about 1" clearance off the crank pulley if a trans adapter plate is not needed. The other engine that will fit easily is the GM 3.4L (the block is only 15" long), but that will need an adapter plate, and maybe some trickery off the crank such as a custom pulley (but who wants a Chevy engine in their Toyota). Some motors have intake plenums hanging off of them like the SHO engine which won't fit without seroius work, and you would really have to use it's tranny also.
About weight, I think an aluminum block V6 (like the 1VZ) would be very close in weight to the iron block 4 like the 5SFE, but I don't have hard numbers in front of me.

I wonder how the VW VR6 would fit. It's not very wide as it's only a 15º V to it, it's 2.8L and I believe an aluminum block too, but i'm not sure. It's not very powerful though with only 178hp (205hp in brand new ones), and it's meant for a fwd car, but they sound great and can be turbo'd too. EIP Tuning here in MD does that a lot with great results, but it's expensive.

I read in the newspaper, that they've made a V6 MR2 in Japan, which can go from 0-100kph in under six seconds. I'm not sure if it's going to go into production yet.

Hate to say it, but I've been on the other MR2 forum, and there are a couple of threads on putting a Camry 1MZ V6 in a MKII MR2. http://www.board.mr2faq.com/forumdisplay.php?s=&forumid=3. I looks like it bolts right up to the tranny, and you can use 2 of the motor mounts, but the rest have to be fabricated. These guys are also planning to put TRD's Eaton blower kit on, too.
I also ran across a site with details on a MKI with the 1MZ in it: http://www.atlantamr2s.com/owners%20rides/joe%20vick/MR2.htm

here is my idea a 2jzgte in an mk1 yes a twin turbo supra engine :D what i wanna do is have a tranny from a 91 mr2 modified to bolt to the 2jz and then u cut out the trunk area in the back to provide more space any suggestions

well if you were willing to sacrifice your trunk, you could probably fit one in. Plus it would lighten up your car a bit after you got rid of all the stuff in between.

Have heard from a Toyota technical training center instructor that a friend of his is involved in a 3VZE V6 engine swap into a MR-2. Said that they were surprised to see the rear end raise up (the aluminum block was so much lighter than the iron block?) from it's original height. There is supposed to be a series of articles about this particular vehicle, but I've looked all over for it since I first heard about it last fall. Would be very interested if anyone knows more about it.

LOL... they fit in with no problems... It is almost a bolt in on the MK2. The MK1 requires a bit of modifing, but nothing big.

You guys have got to visit my Message Board for the lastest and greatest stuff that has been done to the MR2 of all gens.

Sport Compact Car did it in their latest issue, its towards the back of the magazine
:rocket:

umm dude...supras are inline 6's meaning...v6s have been done but i doubt the I6

i meant to add....I6s are alot longer than v6's that engine would almost be longer then a the rear axel

Uh oh... Bill found us :)

There is a whole series in Turbo magazine about their MKII build up with a Lexus V6, that they added a supercharger AND a large T78 turbocharger too. It is twincharged ;) and there is plenty of room in the engine bay for everything. :)

There is at least one V6 MKI out there as well.

It fits.. :bandit: This is a Solara V6, 3.0 L

BRAD BEDELL????

Can it be? Hey man, this is Jeff Fazio.... how have you been? Long time no talk (like 6 years).

I cannot take credit for this amazing yellow work of art, i just came over this site on the net. :D I admire his work, and there must be tons of it done on this car..

Check out the April 2003 issue of Sport Compact Car. They do a complete engine swap to a 1MZ-FE engine. They go through the whole thing. From start to finish. They Even say that it fits better than the stock turbo.

Actually there are many v6 mr2's , one of'em was offered for sale on ebay in march 2004. It was a 1991 with the 1mz engine and the new TRD supercharger for 3.0L. It didn't meet the reserve price but it's still offered for sale on vickracing.com , and these guys are also offering an MKI for sale (v6) with the 1mz and the supercharger, 400 hp on that light-ass car will literally smoke the hell outta the MKII , since there's a 900 lbs weight difference. And they had to do a lotta work to get the right tranny in there too.
the MKII was for $12,500 and the MKI for $15,000 (because of the weight thing). But then again the MKI had just gotten a new body job and a whole new interior so it was worth it.
If I could afford it, i would definately buy the V6 MKI.

It seems most people are swapping in the 1MZ, probably because SCC did that... has anyone swapped in the 3VZ and were your issues the same or was there anything different?

wow all of this is great but how much would it cost do do something like put v6 in a mr2.

nvm

most ppl swap the 1mz vs. the other v6's because they were available in the same year camry. the stock NA (5sf3) in the mr2 is the same as the camry four banger. this obviously means that both engine bays are very similar. it 1mz is about a 60% bolt in swap. you do need to fab. one motor mount and one tranny mount i believe... also, i'm pretty sure that the camry v6 (1mzfe) bolts up to the mr2 tranny, possibly with some flywheel modification.

i was looking into doing the same thing because im not the biggest fan of a four cylinder engine, so i did my research and the 1mz-fe aluminum block bolt's right up to the mr2 turbo transmission according to sport compact car magazine (april 2003), and fits better in the mr2's engine bay then the 3s-gte engine does. All i'm looking into right now is adding power, big power to the motor other than the 62hp supercharger already available for the v-6. im talking in the ranger of "mr2 terror" from sport compact car (471whp on 93 octane). don't get me wrong, if i can't find a way to get some real power out of the 1mz without spending a arm and a leg of money, then, i will tune up my 3s motor, move the 1mz to the back burner as a project motor and mess with it until i get it right and just burn everyone with my 3s; which is one of the best four cylinder motor's out there. if you want anymore info on the swap then e-mail me at earlcarter3@hotmail.com

I've found alot of info sense the last time i was here on the mr2 v-6 swap. Last time i said that i had researched the v-6 swap and found out that sport compact car had done the swap on a 91 mr2 turbo with a melted piston (april 2003) and i was looking for more power options other than the 62 hp supercharger from TRD. Since then, I've found a web site that has done and know's lots of people who have done the swap (vickracing.com) and even has one on the dyno (stock 1mz-fe 172whp & 205lb/ft). Plus, i recently found out that turbo magazine is doing a twin charged v-6 mr2 with a supercharger (TRD) and a custom made turbo kit for the car. So far, they have only dynoed the turbo which peaks somewhere north of 450 on like 20 pounds and have'nt even finished tuning it, and plan to turn it up to 30psi. Just go to search on the web site and type in project mr6 and it will tell you what books to look for. When I first considered the swap i was looking for porche 911 gt2 numbers (3.8 to 60 & 11.8 to 1/4 on 456hp & 457lb/ft), but since then i realized that the mr2 can do those numbers with 300hp from the I-4 turbo motor. So, i'm heading for the big fish's numbers (enzo 3.3 to 60 & 11.2 to 1/4 with 660hp & 485lb/ft) with the v-6. With the enzo's hefty weight (3020lbs) to my supermodel's weight (-2800lbs) I think 450whp will do! You will see and hear from me again with that monster! Until then, e-mail me at earlcarter3@hotmail.com

has anyone researched putting a BMW v6 in an MKII?

How much does does 1mz-fe weigh?
Any info on this swap in an MK1 mr2? :naughty:

has anyone researched putting a BMW v6 in an MKII?
Bmw would have to make a v6 first.

I did'nt even know that BMW made a V-6, but i might be wrong. As to how much the 1mz-fe weigh's, 401lbs (Sport Compact Car April 2003). They say that it's about the same weight as the 3s-gte motor, but I still have'nt found a document that says it.

BMW does make a 2.5 L V6. It is in the 325 Series.

BMW also makes a 3.0L V6 that comes in the M3. I think it would be too big.

The 2002 BMW has a 3.2L inline V6 that looks pretty small.

also has anybody looked into a 3.0L Honda i-VTEC

The 2.5 liter six cylinder, 3.0 liter and 3.2 liter engine's that BMW makes are all straight (inline) six cylinders. There is no such thing as a inline V-6. It's either inline or V. BMW has never made a V-6. Why are you looking else where for a V-6 for the Mr2 anyway? The one that toyota built (1mz-fe) is just as powerful, fit's right into the engine bay and bolt's right to the trans of a turbo mr2, and won't cost you as much to buy or get it into the bay! Plus, it's a toyota! Built to last! I don't care how much power you put to it, it would be just as reliable as the other engine's that you named. Do your homework on anyone who has done the swap and I assure you, that's what you will find.

hey while we're at it why dont we just put the lexus 8 in there ... we might have to lengthen it a little and lose the boot... but we could make it really cool... it might even beat f40's and mclaren f1's! we could call it a cool name like an MC8-R ...just an idea!?

oh.... before we get confusion... i plan on mounting the v8 (not inline v8) longditudally and having a different transaxle...

i heard of an MkI with 5.7L Hemi V8 ! no trunk though...has anyone else heard of this.

so you Know the EIP guys huh? i ran into one of thier red Turboed VW...we were supposed to run but he only wanted to run for $500 dollars and i wanted to run for bragging rights so he talked shit to me

Yeah... And Did You See That S13 With The Viper Engine????

Does anybody think the 3.0L honda i-VTEC would fit. If so how much horsepower would it make. I also thought about twin turbo charging it.

just did some research and found out that there was another guy asking about the hemi swap. he hadn't done it he actually got blasted for even thinking about it. i just met a guy on the street and he told me about it and i just asked thats all. i wouldn't swap anything else but a JDM motor or the camry engine in the MR2. i ahve done a few swaps in my day...a nissan BlueBird and Pulsar Gti-r AWD turbo into a US Sentra, 200sx, G20. and they are daily driven and reliable. Right now we are looking for a motor to put into a US RWD old school Toyota STarlet...we had a rotary in it but it blew. so now we are thinking of a Cresida engine and then boosting it...3s-gte..then upgrade...skyline Rb26...

yeah but the gti-r uses the SR20, as do some factory bluebirds... so swapping them to other cars that use the same engine isn't particularly hard... the 200sx and the sentra both came from the factory with them and i have NO idea what a g20 is. infact out of the 4 cars you mentioned, all come from the factory with an sr20 turbo and awd except the 200sx which still has the sr20 turbo just rear drive. sure you might need different length shafts for a different size car but even the mounts SHOULD work.

why are you so bent on getting a honda V-6, when a toyota V-6 is cheaper and makes just as much power?

i'm thinking he means the nsx engine and it is an outstanding motor.... camry v6 is not a comparison. toyota's competing engine is a straight 6 and won't fit! the nsw engine is actually probably a sensible idea... and being another mid engine similar size car you might be able to make use of the transmission as well and pack the whole lot in... the camry engine is cheaper for a reason ... its a family car... but it will bolt up and it is a toyota... though it doesn't have the potential of the 3s-gte so why bother really.... all depends what you want...

don't crossbreed cars :(

but DO, do a swap like this! :D

Well if he is talk'n about the NSX 3.0 or 3.2 liter V-6's then he need's to straighten that up, because they are totally diferent beast from the regular stock accord engine. I know everything about about the NSX, and it's potential and would'nt dare compare it to a camry's V-6. There is a big difference there; being that the NSX's engine's were built to be in a sports car, and the V-6 I'm putting in my car was made for a family sedan. But, he did'nt say NSX, he said accord. though, with the right amount of tuning this V-6 can and will be a beast. Don't get me wrong though, if I had $40,000 dollars I would buy a NSX, but since I don't I think that the Mr2 with a V-6 swap will work just fine. Espectially, after I finish all of the work that I want to do to it. Also, yeah the NSX's engine would be probably a sinceble idea being as though it's in a mid engine car already, but where are you going to find one without giving up one of you three legs, plus if you already have a Mr2 turbo the camry V-6 bolt's right to the trans. Yes, the 3s-gte motor is a work of art and has potential (980hp at pikes peek was the most I've heard), but so would any car with a turbo on it. One observation that I have made is that the Honda motor's with V-tec lack a little torque but is made up for in the top end with high rpm's, while the toyota V-6 is a torque moster out of the box and has a broad power band. So, with the right amount of tuning and both engine's on the same horsepower playing field and I guarentee you that the toyota V-6 will be at least the same if not better.

the v6 will be more unique, and you'll have bottom end torque!

have you thought of doing a v8 instead? ;)

i know how

I Have never seen a V6 done tho it would probably be less complicated then the V-8 I saw done took lots of modification to get the motor to fit the trunk had to be cut out but it is possible

Good Call Earl... I Hadn't Bothered Going Back Past The In Line Bmw V6, And The Other Bmw V6's (duh???). Total Agreement, Nsx Engine Would Be Very Hard To Get But Ultra Cool... If It's Between Honda And Toyota Family V6's I'd Stick With Toyota!

I thought about the V-8 when gut from mt job told me about a gut they know who has a small block chevy in his, but then I thought about the weight, fabrication, etc. and I said that a V-6 with a turbo would be faster and still have enough low and top end power to stave a V-8 off down a straight away, or street plus I can do the swap for so much more less.

true.. the v-6 just sounds less complicated the one i had seen was from a guy i knew took a tundra V-8 supercharged it and droped it in but it took cuting away the trunk area heavy rear suspension, a custom plate made to adapt the tranny, custome motor mounts ect.. ect.. plus adding counter weight in the frount to keep the weight balanced properly but it was nice when it was done but cost a ton. if i were going to do a V-6 application i would definetly stay with toyota like the 3VZFE then turbo charge it or twin :-) depending on you wallet but even turbo charging a v-6 if not made for it i would recomend swaping the pistons for low compresion pistons and swap valves and cams but thats just me..

Sorry...i've Really Gone Off Chevy's Since Their Last Technical Development In The 40's.

Exactly! That V-8 swap will cost one of your three legs there Sir! So, stick with the V-6. It will be a better around performer and for alot less money. As far as the 3vz motor, it's almost the same motor with the exception of the 3vz's heavy (469lbs) but stout iron block, which is good for a high output turbo engine, and it still uses a distributer for it's ignition system which is cheaper to maintain. This is also a good motor to swap. Good choice and good comments!

well since I have the ONLY V8 MR2, and I will tell you that it is not easy and it is not cheap. the whole car must be re-engineered. Hell I have over $5000 in computers just to run the damn things... but having a MK1 that can do 190+ mph is pretty cool.

http://www.v8mr2.com

and hows THAT handle then?

if bill strong can fit a v8 in a mk1 ya better belive ya can fit a v6

I have a 93 mr2 turbo, and had a good 5 large set aside for the 1mz aluminum block, but there seems to be a lot of "engine sludge" talk about toyota town, maybe I should go with the 3sgte series 3 motor instead..........cause if my engine sludges up, not under factory warranty, I'll burn the nearest dealership down, i swear fore god, i will.
And who knows of a good mr2 man in the Miami area? Summer is coming!

Not only have they put a V6 in an MKI but try a North Star V8! Check this out: www.v8mr2.com (http://www.v8mr2.com)

How about a H-6 like a Porsche Boxter engine and tranny?

Bill Strong still out here? I was watching the Toy-Star build up a couple of years back. Just wondering how this Cadillac V8/MR2MK1 marriage finally turned out. Anyone know of any pics or video of the finished monster? Doesn't look like www.v8mr2.com (http://www.v8mr2.com/) has been updated in a couple of years. Just really curious about this project. :confused:

Bill's car has been raced with the Northstar and stock GM autotragic. He raced it several times, IIRC. Currently, he is trying to switch the autotragic over to the 6 speed (as discussed in my own swap).
