hello everyone its been awhile since ive been here well now that im back im here to stay Bought an 85 Iroc with a 5 spd and im lovin it. This is my third 3rd gen (Other 2 was an 85 sport coupe and an 86 z28). Heres a couple of pics:

 

Congrats on the purchase. Great to see another back into a thirdgen

 

looks like a nice clean car. nice purchase. i always loved red irocs.

 

looks very nice, good luck with it

 

thanx everyone. i was wondering how difficult is it to turn it into tpi? runin tbi right now.

 

Pretty easy, just drop your Iroc off in my driveway and drive away in mine. Then you will have TPI. J/k But that is a really good lookin Iroc and I really wish mine was a 5-speed.

 

sounds like a plan haha

 

DON'T DO IT!!!! lol j/k It's easy and at the same time can be a nightmare. It all depends on how you go about it. There are alot of articles on this sit about swapping to TPI that are very helpful. Pre Planning is the key!!!

I picked up a 89 RS Roller project that was originally a TBI and I am in the process of dropping in a 350 TPI motor in See Here

If you do a TPI swap make sure that ALL the parts you need come from the same donor car i.e. The TPI setup, computer, chip, harness. One of the pains is that you'll have to swap the fuel pump to a high pressure/high volume pump. TBI pumps put out about 10psi and the TPI needs 35-40psi. Plan on half a day to a day doing this...pump is in the tank. If your going to upgrade exhaust this is the time to do it because you can just cut the old off out of the way and not worry about it.

You also have to switch little things like throttle cable and stuff.

If you have the time, a warm place to work on it over winter,all the tools with a little bit of patience added in, then its not as bad as you think to do the swap. If you get all the parts in advance and have time it shouldn't take more than a few days or a week to get done.

 

Thanx for the info. Kinda hard to find a donor car in chicago though. Scrapyards in chicago are crap.
