I don't see many, if any at all, going that direction. Spending $6K to $9K on a rebuilt without going the extra distance with TT, would be really pointless, IMO. You have an engine that is hungry for boost and if any warranty existed - it is now out the window.

Might as well sell you N/A VQ35DE and get the next VQ35HR model.

I dunno, I think it'd be pointless to get a VQ35HR for the current Z/G's....I mean, who's going to even bother to R&D the new engine with the current Z body? By 2008 it's suppposed to be an all new designed body and that's what companies are going to put their R&D money into with new FI kits

I do think most people that'd want a stroker kit would have FI plans, but it gets complicated comparing a 4.24 liter engine to a 3.5 liter engine because 1psi doesn't = 1 psi in terms of air volume going through the engine. 8 lbs of boost on a 4.24L engine is going to produce a hell of a lot more air volume than 8 lbs of boost on a 3.5 liter engine. All psi does is measure pressure, not volume. You could have an intake manifold the size of a swimming pool and still get an 8psi measurement off of it, but that won't tell you anything about that it's holding 10,000 times more air volume

It's more scientific to compare the two engines in NA form with how much more power the engine itself is actually responsible for making

Sorry, I was not clear, as I was not comparing the 3.5 L to the 4 Liter. What I meant was, if one was considering the rebuilt/stroker kit and not go with a FI system, it would make more sense to get the next generation VQ.

The new pathfinders are 4 L VQ35DE, aren't they?

I think it'd make more sense to put an LS1 or LS2 in the Z if you're going to bother putting a new engine in. It'd weigh less than the Z engine too

the output is very dependant on your choice of compression, application, and tune.

i cant wait for someone to try out this stroker kit. I want to see the output it gives. I think someone here we know should definitly give it a try since his motor is already in need to be fixed *nudge nudge nitrouz*

there is no problem with the test car I can assure of that we will have some dyno # in the next few weeks . I can't wait my self, its going to be fun and exiting .stay tuned
Just wondering how the car is turning out? And what kind of numbers it's pushing.

Sometimes the shop car, while very exciting, is the last one to get attention at a business full of customers!

I am sure there are already orders in for the stroker kit. It is just a matter of time.
One thing GTM is good at is taking the time to make sure their work is top notch.

As for 18PSI... I am pretty sure there are plans for more boost then that
