My 1988 Vert LS1 swap

Well it has begun. Doing what is best for the car IMO. Going with a 2001 WS6 LS1/6 speed combo

going in my 1988 Iroc convertible. Also swapping in an interior from a 2000 Trans AM just to clean it up a bit.

Heres the pics of the progress and let this thread be my introduction as well considering I have 1 post on here LOL

Re: My 1988 Vert LS1 swap

Wow... That is one sweet looking vert!!!! Looks like another car to add to my "jealous of how much better the swap is going to turn out" list...hehe.

Good luck with it and for goodness sakes...keep those pictures coming! Im anxious to see how that interior looks when you get it together. I still think if I had a 4th gen TA for my donor car instead of the camaro I would have done the full dash/door panel upgrade while I was at it...

Is that a 4th gen steering column? What kinds of mods did it take to put in if so?

yes, no mods needed!
bolts right in

as a safety in this vehicles however the steering shaft slides about 8 to 10 inches into itself in case of a front impact. Right now I have it slid almost the whole way down. It'll work for now but I will be shortening the steering shaft to keep this safety feature.

Wow! That means that my plan for steering wheel controls might actually work then! Are you going to hook up the air bag sensors somehow so that works as well?

Can't wait to see this done.

Re: My 1988 Vert LS1 swap

Other then the safety feature and steering wheel controls, what is the advantage of the 4th gen column??

Personally, the safety feature doesnt mean much, but i do have a 4th gen console here. Being that its a pontiac one, its not much good to me in my camaro, but if theres a significant advantage, ive got a 4th gen camaro wheel in ym car now that i can transfer

Re: My 1988 Vert LS1 swap

Thirdgens had this "safety feature" also. But it was built into the intermediate shaft out in the engine bay.

The problem I had with the 4th gen column was there was slight difference in electrical connections, but that didnt deter me. Connecting the column to the steering box stopped me. There were wasy to make it work, but I didnt want to go through with it. There are threads on using the 4th gen column and the intermediate shaft as well....

Inside, the columns are pretty much identical though. I still have a 4th gen column sitting around...just in case. But I doubt Ill ever use it.

Car is looking good! Keep the pics comin!

I did true dual exhaust that exited just before the rear wheels, makes for really nice burnouts

SCHWEEEEEEEEEEET!!

I dig it man. That TPI air intake is killing you though. I bet theres a tenth or two just by ditching that restriction. Looks cool though and 12.4 is booking along damn fine.

Yeah Ive got an idea what Im gonna do for the intake that should wake the car up a little more.

Also, I haven't had the chance to change the programming from (4) O2 sensors to (2) and I only have 1 hooked up because the other 1 decided to melt the wiring on the exhaust

Plus some headers and tune are in the near future which would definitely help with some power increase

YEah your in for a big jump in power with those mods. LS1's Looooooove longtubes so bank on 30 ponies or so there plus another 10-20 with the tune and? with the intake.

11.x will be a breeze

Ohhhhh yeah...! I'd think that a well-flowing intake tract, a good tune for the (properly-functioning) O2s & headers would put you solidly in the 11s...

Yeah add decent heads to that formula and 10's are very reachable. I'm liking the TFS heads these days. Pricey but not the priciest and a lot of fast fast LS guys seem to run them.

It's not bad out here. It's pretty much fox body and sn95 dominated, based on sheer numbers.
