Re: ls1 wiring help?
Does the LS1 have a harness from the car it was removed from? And is the harness from the old TPI still in the car?

Re: ls1 wiring help?
If you have a 350 TPI why would you want to spend the money and hassle to change to an LS1? I can see upgrading a carb or a TBI to LS1, but you already have the high performance 350 TPI.

Re: ls1 wiring help?
FYI per wikipedia
Years: 1985-1992
The new 1985 L98 added tuned-port fuel injection "TPI", which produced 230 hp (172 kW) and 330 lb·ft (447 N·m). It was standard on all 1985-1991 Corvettes (rated at 230 hp (172 kW)-250 hp (186 kW) and 330 lb·ft (447 N·m)-350 lb·ft (475 N·m)). Aluminum cylinder heads (Corvette only) were released part way through the 1986 model run and continued through the end of L98 Corvette production in 1992. Optional on 87-92 Chevrolet Camaro & Pontiac Firebird models (rated at 225 hp (168 kW)-245 hp (183 kW) and 330 lb·ft (447 N·m)-345 lb·ft (468 N·m)) 1987 versions had 10 hp (7 kW) and 15 lb·ft (20 N·m) more thanks to 9.5:1 compression and a change to hydraulic roller camshaft. Compression was up again in 1991 to 10:1 but output stayed the same.

LS1
The LS1 was rated at 350 hp (260 kW) and 365 lb·ft (495 N·m) since 2001 (LS6 Intake), 1997-2000 350 lb·ft (470 N·m) in North America, depending on the application.http://www.gmperformanceparts.com/Pa...l.jsp?engine=2 The LS1 was used in the Corvette from 97-04. It was also used in GM F-Body cars with a rating of 305HP - 315HP. In Australia, continuous modifications were made to the LS1 engine throughout its lifetime, reaching 382 bhp (285 kW) in the HSV's YII series, and a Callaway modified version named "C4B" was fitted to HSV GTS models producing 402 bhp (300 kW).

Re: ls1 wiring help?
Some times I wish I did an LS1 swap but I just think TPI is more fun. More thought is required to make the power with TPI but that's part of the fun.
Sounds like you made up your mind about the LS1 swap just do it right & no hacking.

Re: ls1 wiring help?
My friend Jason has already done this swap. He can pretty much do anything with an F-body, wiring, motor swaps, whatever. He also built the harness for my friends LS1 swapped 2nd gen Camaro.
He is mostly familiar with 4th gens, but has worked on plenty of 3rd gens as well. He is pretty well known on the Western section of the LS1tech forum. Tell him Jeremy referred you. He will come to you and look at the car and setup a game plan. (714)9-ONE-7-SEVEN532
He is busy with a lot of projects sometimes, including his own car, so if he can't do it for you let me know. As a last resort, I can refer you to the shop that built the harness for my LT1 swap.

Re: ls1 wiring help?
Yes the LS1 has reported MPG in the range of 25-30 while stock and slightly modified. If our SBC's could use street heads that were 18* instead of 23* then yes we would have better MPG and power, too. I'm not denying that LS1's are better than TPI's. I'm saying its my opinion that swapping a 350 TPI to a 350 LS1 is not something I would recommend, due to the cost, and hassle.

Re: ls1 wiring help?
Some members think you will "bastardize" your car if you take out the L98 but ironically the fastest TPI cars in so cal are running 4th gen transmission, rear ends, brakes, etc. lol
I have a thread in the LSX swap forum w/more details.

Re: ls1 wiring help?
im proud of building my daily driven 3rd gen/ 4th gen bastardized which never gives me any problems .
mpg is great. drive ability/reliability is great. and hwy runs are fun. im 21 and its hard to stay off the pedal but i have so much more plans for it.. ive just begun..
wiring was fun btw. its pretty cool when you attempt it your self because if you ever run into the problems you're a step closer to finding the issue.

Re: ls1 wiring help?
Back on topic, the company that did my harness made it very easy to wire up and also reprogrammed my computer to bypass VATS and other features that don't carry over from the 4th gen.

Re: ls1 wiring help?
Exactly right off the railroad tracks, i forget the guys name but they were real cool.
As far as Tpi is concerned im Sticking with TPI, i feel it fits my engine bay better. Besides i can do minor upgrades as my wallet allows, an lsx swap is throwing a chunk of money all at once to get it going and what you end up getting is a stock ls1 motor combo. When the time comes for an ls1 i'm sure i'l just pick up an 01-02 SS

Re: ls1 wiring help?
if you find the deal its well worth it.. just research.
a lot of people think ive spent so much money because of the appearance of my car.. but in reality the only receipts ive had for performance parts arent really performance parts a factory clutch, a used intake, a walbro fuel pump, mufflers and labor for a temporary y pipe and a tune.
if you have the skills, knowledge and availability its a good opportunity to do something you want.
ls1's look good in almost anything its just a new idea
