This swap will cost you about 12 g's in the end even if you do it yourself.
The motor is 4500, then if you wanna stick with twins two garretts are gonna cost you about 2500 bucks for about 650-750hp, internals are about 3000-4000, that's 10-11 grand plus other stuff that's gonna break ie oil pump, water pump, etc... Don't forget the RB25 tranny your going to have to get because the modifications you have to do to use the RB26 tranny are rediculous.

You need motor mounts too, custom oil pan, new suspension for the added weight, driveshaft, and I'm probably forgetting some things.

I picked up the RB26 out of a R33 GTR and it was in decent condition but needed a new water pump and oil pump and the turbo's were shot.

Anything over 450 on a stock block RB26 REQUIRES larger turbos because your going to blow up the stock ones, fuel supply, and a good tune.

I'm not trying to discourage you or anything but I just want you to realize how expensive this is going to be.

Also when are you going to actually use anything over 700hp to the wheels on the streets? A G with anything over that isn't going to handle too well. A G with 600hp won't be much better without a really good suspension, chassis reinforcment, and some really wide tires. You've gotta remember the new vettes have 505hp to the crank which is like 440-450 hp to the wheels and they don't even handle that well and they have an actual frame that's fairly rigid. It's american junk though but it's stock suspension and frame is way better than a G's cause a G is a uni-body. Have you ever seen high-hp supras? They flex like crazy.

I think 700hp would be a good goal on a fully built, cyroed, balanced and blueprinted VQ35. You'd get better spool up on the VQ along with more torque and better handling characteristics than a RB26. I'm currently in the process of TT my VQ with the JWT kit and I'm doing a full build, cryo, and balance and blueprint, and stroking it and looking at about 650 rwhp and about 750 lbs of torque, possible more, and trust me, you will blow pretty much anything on the streets away with that amount of power.

If you like straight line racing, go with the RB as it has more high end potential, but if you wanna through some curves in there stick with the VQ.

You don't see many 1000hp supras taking turns do you??

EDIT: Ok, I just found the turbo story with the guy's G coupe that has a RB26. He's pushing 620 to the wheels but he had to have his rods shot-peened and his crank knife-edge honed. Might as well go with new internals cause those two mods to the stock parts aren't very cheap.
