Personally, I prefer the looks of the C4 over the C5. If they don't have the 92-93 kit available by the end of 2019(I'll wait that long if need be), I'll probably sell my 93 convertible and buy a 94 or newer model, even if that means going back to a coupe model (targa isn't that bad).

Me too.

Wouldn't bother me either way since my biggest problem is having to bring it to one or two "specialist in old stuff" at the dealership if I have problems. IOW, bring it to the couple of suckers who can't walk away from that job because they have done a couple of them and not that they are good. Also for me, tuning is a big component for when, not if, when I make some upgrades. That is a deal breaker for me if nobody wants to tune or can fix when I cannot.

I have officially started working on it and already hitting the issues with my current modifications as usual. I am working on trying to get some videos. but just know I haven't forgotten about ya'll!

Also the argument can be made as to if this kit is worth it. I personally think for the LT1 fan club it is great and their sole market isn't just C4s. You can LS anything and to me that's part of the problem. If you want to keep your car original and be able to have more life to your tune then this maybe for you. Also I would assume like anything price will come down the more people make the purchase. Even if could be the cost of a few optis that may make it worth the price... right?

Yea, any car can be LS'ed. But why would I replace my perfectly fine LT for a LS for +$5000, unless I was going for a big CiD increase, ie LSX (LSX would be significantly more), when I could make my LT just as tune-able as the LS for $2500? Honestly, I could care less about keeping it original. That's why I'm interested.

I agree but in the end it depends on what you are trying to do. For what I have spent I probably would of been better off going LS instead of trying to keep my LT1 alive but I had Zero knowledge at that time and thought it would be cheaper. My goals were 600-700 rwhp so I am not trying to go LS crazy and hit 1000+ hp either. I think for the price and getting rid of an opti with added tunability is who this kit is for I am just an odd ball

Yes, any car can be LS'ed but with provision. I have seen an LS motor in a Miata or similar car. You can put it into a 3rd Gen F-body where there is little electronics. But in a C4 or say a Mercedes or another car that has a CCM that has a say in matters, you might have to either fork out bunches of money or forgo certain features. I checked with a few speed shops and that was pretty much the answer. So, if I wanted everything working, place credit card here and don't come back till we call. Or you can do some wiring work and get some things working but not everything.

IMO, for $2500, IF this is plug and play and doesn't end up costing me a fortune, I could see stuffing in an LS motor if I wanted to make changes that would require tuning. Until I see the final product, I have no clue if it will be workable. I think you will have to do the mounts and if you want, might take a little work. On my L98, it will take a lot of work and nobody wants to commit to how much it will cost or they name a ridiculous sum.

Very cool man! Good job on getting it done
Dumb question. Will any obd2 code reader be able to read codes from now on?

Glad you were able to get it to work with the BlowerWorks 6/8 Damper

Kudos to those guys at Torqhead for building a viable product for these cars, and good job to you for providing additional feedback for them so they can make their product even better for other C4 owners.

I installed EFI Connections' 24X system in my 89 a few years ago for the same reasons as you, but they were very unhelpful and absolutely uninterested in the Y car platform.

The upgrade of the PCM is definitely worth it. Those who say its not are still surfing the web with their Commodore 64....

Word is to swap out the original 92/93 engine harness for a 94/96 harness. If my Accel gen 6 is beyond repair, this may be the way to go.

Tom400CFI

I have a complete Gen 6 system if that would help you. CHEAP. $100?

I'm very excited by what I see considering I have a nice 383 ysi setup. I'll have to keep tabs on what it takes to swap out to a 94-96 harness if a 92-93 solution isn't found.

Sleazy Rider

good writeup!!! going to be putting a 383 into my 96 later this year and i think gm pulled their pud with the optispark so i looked at torqhead and think i will purchase this product when the time comes.

1993C4LT1

If i keep my 93, yes, I'll do the same.

Any updates? Curious to see how it's been running after the install.
