can it be done?

 

I think it can be done

someone at a local shop mentioned the idea to me once.

It's an interesting concept

It'd probalby be a little heavier

You'd have no aftermarket support at all other than internals. Meaning you'd have to get a standalone ECU, custom headers, custom FI kits, etc

you can get the AEBS 4.3 stroker kit with 11 or 11.5 compression ratio and have pretty close to LS2 performance and still have full market support other than you'd probably need an ECU flash

I'd like to see someone do it

 

I was just thinking about this the other day. The idea sounds possible, as the ls2 is just as wide as our motors (I think so, no positive). It would sure be a unsuspecting powerhorse. You could also crank more HP out of that motor with all the stuff that will be produced for it. I believe i heard about some guy that did some bolt ons and maybe a cam and got 500hp out of the 6.0 v8.

 

i wonder about the LS2 engine that's going in the new Z06 - would that be the same size or bigger?

how much do LS2 engines cost?

 

I work for a GM dealer, it could be done, but it would be very expensive, engine, trans, rear axle, and all the engine management supplies. I agree with sentry, it would make more sense to spend half the money on your VQ and get a lot more power, plus the torque curve is much better. not to mention the gas mileage. I must admit, it would be cool as h*ll though!!!

 

oh yeah, forgot - you'd probably need a whole different transmission or some sort of crazy custom work to connect them

by the time you could do it, you almost might have well just bought a corvette

 

I think youre the one that just called and talked to me about this and I stand behind what I told you, APS TT+engine build!

 

Anything is possible with money. Are you willing to put tens of thousands of dollars into it? I mean, in Japan, you see syline motors in everything, and supra motors being swapped into many different cars. It's all just money and custom fab.
All of which i don't think would translate into a worthy combo. I mean, it's a ton of money, and you can put all that into your car now and make the VQ just as powerful etc....

 

The new Z06 motor is the LS7. It is a 7.0 v8 with 500hp. And I bet the engine will be very expensive.

 

What he said.

 

Look for the LS7 crate engine to be in excess of $12,000 from GM, that's M.S.R.P., if anybody wants one, I'll sell it for 10% over cost...probably about $8-9.5k...not available yet.
In a side note, the LS2 6.0 in the standard Vette pushes it to 60 in 4.2 seconds...the Z06, 3.5 to 60 and a nasty qtr-mile, we'll still murder them both on an autocross course.

 

The LS2 engine M.S.R.P. is $8K...just ordered one for a customers 32 Ford

 

it's interesting to think though that even with the AEBS stroker kit with 11 ratio pistons you'd be around I think 380 crank hp - being a little optimistic maybe.

Whereas the LS7 will do 500 crank and from what I've been reading it seems like it'd be pretty strong for FI - just gotta lower the compression ratio. It has titanium rods and valves if I remember right.

hypotheically, if you got the LS7 and somehow got the APS kit to hook up to it (via custom manifolds etc) with the stock 8psi setting you'd be around 570ish whp

i'm kinda pulling those figures out my butt though

it could possibly be worth it depending on how much the LS7 can take as far as boost goes.

the other option of course being getting a sleeved AEBS motor that's bombproof and just crank the boost way way up. that's going to be around 13k anyway to get it and have it installed. Kinda makes you rethink the LS7 idea a little - you'd need a standalone ECU with the LS7, but at that point you'd probably want one anyway for tuning purposes.

It's when you factor in needing a different drivetrain/transmission that it isn't worth it

 

Screw an LS1; If your gonna gut the car enough to slip in a V-8 just go with a bombproof old generation small block chevy with Magnusun blower and standalone engine management. Easy to work on and parts are CHEAP!

Put a TH400 Auto behind it an a Corvette independent rear center section and it would be a BEAST!

Some may consider this as sacreligous but it's been done to the Z car since the 240Z

 

The Z's ECU and GM's ECUs are night and day and fully integrated into other car systems.

Do you understand how much twin turbo kits for Corvettes cost? You can't just put the turbos from the APS kit on the LS7 and expect them to work.

1. 8 psi would be equivalent to 850 horses on the LS7. The turbos APS uses only flow enough air for 700-800 at best when properly matched to the Z. They would max out at about 5-6 psi on a Corvette.

2. You would need manifolds that are
a. custom made for the LS7
b. custom made to fit the APS turbos
c. somehow magically fit inside the Z's engine bay

Realistically, you're looking at $15K for the engine and transmission, $8K for the APS kit, $3K for the manifolds and driveshaft (oh wait, the Corvette's tranny is in the back, need a different transmission now too), and at least $10K for ECU development.

You would be better off (and save money) buying a used Z06 and supercharging it.

And on a final note, Esprit put 11.0 : 1 CR pistons in a Z and got 370 at the crank from it. If you put in the AEBS stroker setup with 11.5:1, the math of increasing the displacement says at least 450.

 

I did a search for the FX45's V8 and didnt find a anyone tring to drop one of those puppies in.

Now granted I know its not tuned for perforance, but wouldnt that be an easier fit?
