I know i'm gonna swap engines soon on my 2000 civic. Its the whole reason why i bought the car. I also have a 1969 Camaro that has lots of low end torque. Take a peek at it here: http://webpages.charter.net/turbolaxx/1969camaro.htm

I love this car because when you step on the gas at any speed it hauls buns! Takes off like a rocket basically. I kinda want that feeling in my honda. I know i wanna go with either a B20 or H22 block because there is no replacement for displacement! I want to know if it's possible to turn either of these motors into strokers? That should give me the low end torque i'm looking for...i think. I know i also want to turbocharge my future engine. Do strokers go well with turbos?

So bascially i want an engine that will have lots of "go" power pretty quick. I dont think i want a supercharger. If anyone can think of a good engine combo let me know or give me links to similar builds. Thanks.

well you could use a 95mm crank with your b20, that will give you good low end tq. a turbo will work but i would recommend a small turbo as with the 95mm crank, peak power will be low

bwahahhahahah thats some funny shit right there :grinno:

put together a turbo kit for your D-series and you'll rape the @#$3 out of a b20 or h22.. i know i will in a few weeks when i put my kit on.

if you've got a camero for racing i wouldn't put to much into a civic. but for 1000 bux you could put together a decent home made kit. or.. up the price and get better and better quality parts. its all up to your budget obviously.

don't underestimate the D

There are a lot of different things you can do to increase torque. However, you just have to realize that Honda motors aren't tourqy motors.

I helped a friend of mine with a 95mm crank into a stock deck B18C5 block, and it wasn't pretty. The piston pin was completely through the oil ring, and almost hitting the first compression ring. It only went about 9000 miles before it started to see some serious blow-by and we needed to re-ring it, I wouldn't do it again.

Low end torque huh.

Wait...you're posting this in a Honda forum? :spit:

i'd have to beg to differ on that one. a forced induction d-series generates pretty good torque numbers. infact my buddy is running 193whp/187wtq on a stock d16 daily driven. and in a 2400lb chassis thats plenty to get her movin

I suggest a turbo and a Venom timed nitrous kit, this way while the turbo is spooling you have the nitrous launching your car and once its spooled, it shuts off.

^^ thats good for a BIG turbo. but on a mild turbo setup on a D i'd say its not necessary and dangerous to the internals. unless you've changed out the bottom end etc. its really late. i need to go to sleep

if you guys used the right length rod it shouldnt have been like that. i mean a 95mm crank in a b20 is gonna be like a 1.30 r/s ratio. but the 99-91 preludes used 95mm cranks so yeah

lol, doesn't matter what the rod length is when the deck is about .8" too short for that much stroke. What rod length would you use :rolleyes: That's a 3.75" stroke with basically a 5.4" rod in an 8.2" deck block. That's the same deck height as a 302 ford, and NOBODY makes or will make a crank longer than 3.5" for that because there is no way of avoiding problems. We used a stock LS rod (5.394") for around a 1.44 R/S ratio, which really isn't that bad, but there is nothing you can do to fix the piston pin issue. You could run something like a 5" rod, but that motor wouldn't last 2000 miles before it completely tore up the rings spinning 8000+ RPM's.

if the deck height is 8.2" like you said minus the stroke 3.75" and you get the rods length 4.45" so why cant you get a 4.45" rod and it will be all good ? and with a 95mm crank you shouldnt be and dont need to be taking it to 8000 because peak power will probably be at like 4500.

For starters, to calculate compression height you take the deck height minus HALF the stroke and the rod length. Secondly a 4.45" rod with a 3.74" stroke would actually pull the oil ring out of the cylinder at the bottom of the bore, that motor would not even run. If, by some miracle of science, it could run having a R/S ratio of around 1.19 WOULD adversely effect the motor, the piston would be incredibly unstable and destroy the rings and cylinder walls in very short order.

Thirdly, here's a graph of a 95mm stroke turbo car with a small turbo, and power is still basically increasing at 8000. With a larger turbo like we were running power will peak higher.

i know you gotta cut it in half but i was just saying thats how you get rod length. all you need to do is find the length of the rod and the stroke of the b20. minus the stroke of the 95mm crank and then you got your rod length. it wouldnt be sticking out because everything is the same length.

also what motor is that 95mm crank in, in that dyno ? and also thats a very nice flat tq curve, i wish i could get one that flat for that long. how big was that turbo ?

those old b20 preludes use that crank so it does work.

No, that isn't how you get rod length. If you tried to run a 4.45" rod on a honda motor of any stroke the rod would be so short that when it comes to BDC it would pull the piston right out of the cylinder, it wouldn't work. You don't "get" rod length, you pick a suitable stroke and rod length, and figure out the CH of your piston from there.

It was a tall deck dart motor, 81.5mm bore, 50-trim turbo.

like i said before, i was being very general, not exact but if you need exact here it is:

that is how you get rod length. find the total length of stroke and rod then subtract stroke from new crank and the left over number is how long your rod needs to be.

for example:

ls rod length: 5.394
ls crank length: 3.504/2= 1.752 (89mm / 25.4)
add together: 7.146
95mm crank: 3.74/2= 1.87
subtracted: 5.276

you dont need deck height unless you decked the block. you want to find the length at stock because if you make it any longer than stock then you may start to run into problems which is why you want to keep it the stock length so you just find the length of the stock components then subtract the new stroke so you find how long of a rod you will need to make it the same length as stock. which i found out comes to 5.276 which gives it a rod stroke ratio of 1.41 which is doable in a motor.

buy a Mustang or a Camaro.

Are you blind or something? Maybe you can't read? The thread starter stated in his first post he ALSO has a CAMARO...so he's stated he already has ones. Flaming like this will not be tolerated here @ AF.
