should be the same. only real differance you may find is with keeping the factory tach. you just need to program the pcm for the v6 instead of the v8 thirdgen style.


your starting out with lighter springs so I guess that should be fine too.


bassically it would come down to the rear diff which most change out anyway

 

V6 and TPI cars have port injections so they have multiple INJ fuses in the factory box

LS1 PCMs use a 4k PPM output for speedo
V6 and TPI cars use a 4k PPM speedo while TBI cars use a 2k PPM speedo

V6 and TPI cars use a high pressure pump. You 'could' reuse the factory for these cars

Factory manual cars will have the reverse lights wired thru the C100 connector
Factory auto cars you will have to figure something out for

 

Sorry...but you should never use the stock pump from a v6 OR a TPI motor... LS1s like high, reliable, constant pressure. You are taking a risk using the older pumps.

Factory auto cars have the reverse lights in the NSS...under the console. Easy as pie to tap into them and make things work.

There is nothing to worry about. You wont run into any obstacles that will keep you from doing the job. In fact...if I were to do another car, Ide probably search for clean v6 cars since they're a good bit cheaper and easier to snag.

Thanks for the heads up guys.

I swapped an auto/tbi car before so that would explain all the problems, seems that a v6/tpi care is ideal for this situation.

I've been trying to find a 91-92 Z28 vert for a reasonable price, but they are nowhere to be found, people are charging over $6K for some and some are getting close to $9K

Have a few leads, but obviously everything is slow around christmas.



For the wiring harness on the car, how extensive is the process? Is it alot of splicing and etc, or does everything connect up if you buy the wiring harness?

 

I suggest buying a harness from a lsx (cars) or lqx (trucks) vehicule and piece your own, wire by wire. That way, you can accomplish a perfect custom job to your application, and eliminate every wire not needed. That is, if you have the time to do it. Its really not hard with the correct wiring schematic and pcm pinout. All of the info is already contained in the stickies and ls1tech.com.

If you want to buy a complete, swap ready harness, it should just be a matter of plug and play. Maybe a couple of wires to connect to the + and - leads, and to the gauges.

Look @ my cardomain, I built my harness using a 2002 Silverado truck harness.
