I dont want to post this against being a supporting vendor but my email has EXPLODED with people wanting info/help and prices on having their c4 vette swapped to ls1.

Soooooo it would be easier to just post this than reply to 30 emails.

Weve now done two ls1 swaps in c4 vettes and can offer them as a complete turnkey install job. We offer this as a 375 horsepower LS1 (mostly stock) or as a 475 horsepower engine for an additonal $1000.

The cost on this swap is $9000 installed

Including parts/labor of removing your old engine, everything. You pick up the car as a turnkey car. Smog legality available at additional cost (not cheap), including any

You bring us your 84-91 Crossfire/l98 corvette.

We provide the LS1/4L60E tranny, custom built headers, motor mount plates, wiring harness, bracketry /w Alternator, powersteering pump, waterpump (a/c is extra $),
Complete Fuel system upgrade and fuel hookups,
Install the motor, we wire everything up and do all customizations
Custom length driveline
C-beam modification for installation
Complete custom exhaust
Complete custom ECU tuning and Chassis dyno tuning

Addons:
Id approximate a stock motored ls1 c4 with proper torque converter/gearing should run high-11's to low 12's easily...the race weight of the car being 300lbs less helps as well.

$1000 Engine upgrades The motor will be a 475 horsepower LS1 /w no loss of gasmileage or driveability. The car will be an easy mid 11-second car @ approx 118-120 mph.


With an ls1 you will
A) Get better gas mileage, currently one swap gets 23 mpg /w a TH350 no overdrive
B) You will shed 200-350 lbs from the nose of the car
C) Reliability and horsepower is unmatched
D) This can be done complete smog legal with little effort

What will the a/c option run?

 

aprox $500 for the custom bracketry, custom lines,rechargine the system and fittings to use your existing working a/c.

I take it the price is the same for '91+ LT cars?

 

pics :confused:

 

So if I'm reading this right the 9k comes with a tranny? What if you have a 96 with a stick? :yesnod:

 

:lurk:

 

Yes this will include lt1 cars. If youd like to use your existing engine/tranny toward the price of the install, we can arrange something on that as well.
(then wed use your l98/lt1 toward a swap in something carbureted etc)

Yes this includes the transmission. I cannot estimate the swap with a T56/Zf-6 because i have no experience on using a t56 in a c4 vette yet. It is easy on a older car, but im not sure if a zf-6 shifter will come up in the same place as a t56 and also there are probably issues with mechanical/hydralic clutch differences etc. We could try and bolt your zf-6 to the ls1, and the price would go down, but im not yet familar with the details. I'll have pictures posted of our swaps eventually..but we are trying to avoid having alot of the stuff that took us alot of time to R&D copied from pictures of our installations.

How much to buy the kit ?

Vic

 

If you want to do the swap yourself. I can provide you with all the parts (custom headers for a c4) etc but cannot prove the bracket changes, driveline, c-brace etc because we do that on site and we make them to fit.

All the parts that i can provide including motor/trans would run you in the $5000 range. You would still have some little things to do (driveline change, c-brace mod) but not much.

 

Questions:

1. Are these new/rebuilt engines and transmission?
2. What year would the motor be?
3. Is there a warranty on the engine and transmission ?
4. What is involved to get them smog legal in CA?
5. How long does the swap take?
6. Where are you location in Ca.

Thats all I can think of for now...

How so?
What weighs so much in an L-98?

 

Im guessing the LS1 uses an aluminum block???

 

:withstupid: LS1 is all aluminum :D

 

yeah, well my L-98 block weighs 145 pounds
an aluminum block weighs about 90.

So I can see 55 pounds there.

Then the intake, so what maybe 30 pounds saved there ditchng the TPI.
and the removal of the AC, maybe 35 there?

So I can see 120 removed.

200 -350?
:skep:

 

I have to agree with Bill , where does the 300 lbs difference come from ? The Alum block vs the Iron block is the only difference, maybe at most it would be a 100 lbs difference. The later L98 heads are Alum, so there is no weight savings there.

Thanks

Vic

wow..$9k huh...hmm..Depending on if that LS1 was a brand new unit with a warranty of some kind, that might be worth it. For $9k, I think I could build a pretty wicked small block. :reddevil

 

You can't just look at the block and intake
Block - 50-60 lbs
Heads (AL to AL) 5 - 10 lbs?
Intake (My Tpi wieghs about 40!) 35lbs
Water pump - 3 -6 lbs?
Brackets - 5 - 10 lbs
And in their case A/C - >50lbs
lighter crank
...

You have to add up all the wiegh reductions GM engineers did to the whole C-5 to appreciate the LS1 swap. For the $/Hp I wished I'd gone LS1!

 

I spent $10K doing it right...there are a lot of $1000 gotchas not related to short block

 

Did I miss something here or are the LT-1/4 6spd guys not a player here? I surely don't want to give up my 6spd. :nono:
