Re: Q45 motor in a Z?
no....but i have a suggestion for those who want to try.... screw the q, put 10 grand into your stock engine (scary, huh?) and then give me the other 30 grand you'd spend on the infiniti. then take a look at what i'd be doing to mine!!!!!

Re: Q45 motor in a Z?
Its just a little bit wider, but not by much. Its mainly just wider fenders and slightly wider wheel stance that makes it look bigger. I also think there is a few inches more length in the engine compartment. The Q motor will be pretty expensive to get. You can probably get one of those newer Corvette engines with DOHC. I forgot what model those come in. ...or maybe not. Those might be pretty rare too. The Q45 is only 4.5L while other V8 engines will be 5.0 to 6.2 in size.

Re: Q45 motor in a Z?
there are no corvette dohc motors. in fact, there aren't any standard production 'vettes that have overhead camshaft design. The new z06 has an ls6 motor, but that's still the same pushrod design used since early 50s, just severely worked over to make 405hp
other smaller displacement import v8s include:
bmw 4.4
audi 4.2
lexus 4.0 and 4.3
toyota 4.7

Re: Q45 motor in a Z?
i think chevy stuck with pushrod design because there are less moving parts, therefore less prone to failure, and easy/cheap to replace. It's a simple and very effective design.

Re: Q45 motor in a Z?
Im not so sure about the broad torque spread. Here in Australia, we get the LS-1 engine in the Holden Commodore (a large RWD sedan) and believe me, that engine is happiest at high revs. Pushrod engines do have certain advantages, they are a fair bit shorter and narrower than the DOCH 5.4 V8 Ford uses here.

Actually, that's not entirely true...
Chevrolet made the ZR-1 Corvette with an all aluminum LT-5 DOHC motor designed by Lotus. http://www.zr1.net/ZR1_specs.html
