Turbo problems <STOCK>91 eagle talon TSI

hi, i have a 91 eagle talon tsi, im gettin 8 psi to the floor in the morning when its cold and it takes about 20mins of driving then it finally shoots to 14 and fast, but it seems faster in the morning when i first start it and its faster at the 8 then at the 14 if this makes since lol, only thing is it runs great has the muffler right at the end of the downpipe, and a k&n filter other then that its stock and does 0 to 60 in 10.30 seconds isnt that bad? its an automatic
what should it do 0 to 60 in cause it says stock it shoul be 6.4 seconds or 7.1 er suntin around that range.

Do a boost leak test, and also do a tune up. Change plugs and wires if they haven't been done recently.

yea a 91 tsi should do 0-60 in about 7 seconds with A/T. Maybe add a bit more cause the motor is 17 years old. But ten is too much.

You should be able to hear it somewhat. Make sure to do a boost leak test. If you car is hitting 14psi and feels slow then you may have a boost leak causing the motor to run rich.

ok suntin weird happened i was drivin the car , and like 30 mins of driving i shut it off went inside for bout 20mins came back out put it to the floor and it set me back so hard it was pressin on my shoulders madddddddddd fast
, it has never done that before so i dunno what to think now lol, i got autolite platiums and ill gap um at 0.28 and see what happens and maybe do a compression test first and see cause the car runs awesome

HERE IS A PIC OF MY CAR

161,000 MILES ON THAT MOTOR

i got autolite platiums
found the problem... platiums dont work for shit on the boosted 4g63... trash them for some NGK BPR7ES, unless you going to run high boost in the near future, i have heard good things about the NGK BR6ES... cap .028... :2cents:

Whats up with the 97-99 front bumper cover?

Whats up with the 97-99 front bumper cover?

Yeah, never seen that before.

And it almost fits.

Yeah, never seen that before.

And it almost fits.
didnt even notice that... it doesnt look that bad IMO, if you could get it to fit better with some custom work from a body shop, that wouldnt be to bad at all... change those plugs and let us know how that helps...

I actually really like that front bumper on their. Get that side marker fixed and like they said trim it up a bit and it looks really nice with a very interesting little mod!

thanks guys, yeah ill hav it fixed, well i got the autolite platiums installed, and it seems to have a little more kick to it all the time, jus have to figure it out in time i kno its not a motor problem cause it runs awesome and doesnt burn a drop of oil...[

hmm not a very big fan of the blue on the interior it just doesn't seem to match very well and the contrast is too much and its too dispersed. But to each his own

:1: looks like a chinese food over cooker (rice) :rofl:

why did you go with the Platiums? the BY FAR best plug for this motor is between the NGK BPR7ES and the BR7ES... just FYI, if you turn up the boost, those plugs will misfire...

yeah wel my fav is the gauges, the rest has to be all redone anyway cause i got to get the vents and stuff that broke


lol cause my friend had those plugs and im broke to do anything to the car, but i will get the ngks asap, i dont even kno how to turn the boost up ive never messed with a turbo.

hey man i did not see a after market boost gauge. how are you telling how many pounds of boost. if it is off of the stock gauge then there is no telling how many pounds of boost you are running. long story short i had the same problem. the reason you car spools up boost quick when yoiu first starts it is because the differend weight in oil. then you first start it the oil is cold and there for less pressure on the turbine. oh and i bet your problem with the boost is you probley have a leak in the wastegate port. i had a old turbo in my first gen and when i replaced it i realized that the waste gate had a big ass crack inside it. my turbo was taking forever to spool up and my car was slow as shit. the best way to fix it is to replace the turbo or at least pool it off and see if it has a crack. once i replaced the turbo my car got fast as shit. oh at the auto first gens have a really smalll turbo its not the 14b so if you try and use a 14b or 16g then you will need new coolent lines.

thanks i think your right, well my turbo says TDO5H, sumone told me that means its a 16g? is that right, and yeah im runnin off the stock boost gauge

get an aftermarket boost gauge, you may be hitting fuel cut causing the ECU to do what it needs to do to keep the motor from going "BOOM" so... be careful, i would try to keep it out of boost untill you find out what turbo you are running, where the boost is set, and get a decent set of plugs in their... then you can have some fun

yea i agree i would not run it hard intill you get a gauge. but buddy has a 350 z and we put a turbo on it. well he did not have a gauge and the turbo said that it would auto set at 8 pounds. well he blew is motor and we replaced it and hooked up a boost gauge he was running like 25 psi. cost him 4k. so be carefull.

oh and tdo5h from what i understand is the size of the turbo housing. not the turbine or the wheel.

Haha turbo's auto set at 8 psi. Who gave you that timbit of information>?

ok need some help i checked my trubo out, and were the 4 bolts are on the manifold that hook to the turbo in that housing there is a 1 inch hairline crack, is that why my cars so slow? and when i went to push in or out on the wastegate it would not push in and took alot of strenth to pull it out is this mean thats ok?

A cracked 1G manifold is common. Either find a 2G or EVO III manifold. The crack will only get worse so if it's not big enough to hinder performance now, it will be in the future. The wastegate actuator arm won't move very easy by hand if working properly.

hey dude take the pen out the the waste gate that connects to the turbo and see if the little peace that the wastegate hooks to will turbo. it should turn easy as long as the wastegate is not hooked. if it does pull the wastegate hard as hell and it shold pull. if you have any problem let me know i have a 2g exhaust manifold il sell. also i have a t25 turbo and some other shit for these. im about to sell my awd talon. kids.

yeah i did that stuff the wastegate arm is hard to pull but it does, and i took the pin out the little things moves real easy.

dude I have an extra 2g mani if you want :)

Could i use the 2g manifold u have on my stock tsi .....if so how much do u want for it???

yes you can but I sold it already for 40 bucks

maybe u guys can help me out.i have a 1995 eagle talon tsi and when i first bought it the turbo would it at 3000 rpms and it would just fly through the other rpms.but now i punch it and it feels so slow.i changed the gasket from the header to the turbo and i changed the gasket on the down pipe.im running platinum iridium plugs.ive had them for like 2 months.u think i fried them already or i just might need a new turbo?

Welcome to AF, glad to see your using the search feature and looking at older threads but you should have made a new thread ab your problem.

I would check for boost leaks if I was you. Thats usually a good place to start. Search on google and you can find out how to build one cheap.

Copper plugs only. Ditch the snake-oil plugs.

its smoking black like hell idnt know why.slow at low rpms after3000rpm it goes quickly,,:runaround:6 bolt with all metal pipping knn 2.5 down pipe 16g turbo WELL I HAVE 90909090 COMPRESSION JUST GOT A HEAD FROM A MACHINE SHOP NEW VALVES AND SEALS SO HEAD SHOULD BE 100% BUT HOW CAN I CHECK THE BLOCK SHOULD I PUT COOLANT IN THE CYLINDERS .ALSO CAN I PUT 2GEN PISTONS ON A 6 BOLT WHAT HAS TO BE DONE???
