Would two of these GT45s be overkill for a 6.2 LS3 with forged pistons/rods? Looking to make as close to 1000HP. Car weighs in at 3200.

I am going with 2 70mm (similar size to most of the ebay gt45s) on my 5.3 Given I will have a large stall and don't expect to see full boost before 4500 rpm.

I'll also be going with an auto. I'll be using a TH400. I'm just not too sure on the stall yet. I was thinking something like a 4K or so.

Anyone else have any opinions on putting a pair of these GT45s on a stock cubed LS3?

Im into a stock ls1 346 intercooled rearmount setup, any suggest on the size to buy? This thread gave me hope to go turbo on a on3 or similar unit.


70mm?76mm? What AR should i look for?

I've got a supplier in china that sells me Ball bearing GT35's for like $200 for a CHRA and like $400 for a complete turbo. I'm sure they can supply bigger turbos as well.

How good are those ball bearing turbos? Do you have any experience using them?

He is a new supplier as far as the ball bearing turbos but not for other turbo parts. I normally use him for my industrial turbos my company remans. (each turbo weighs over 1000lbs) and he has been solid as a rock. Not one problem with a turbo or part so I trust him. I'm gonna be putting these BB turbos on some projects so I'll keep you posted.

Better check to make sure they are actually ball bearing. I bought a Chinese "ball bearing" GT35R size turbo once and It was journal when I took it apart. Still, it is a decently nice turbo. It has been on my brother's SR20det powered 240sx for a while now and boosts pretty good.

The on3 ceramic ball bearing 76mm turbo I bought last year is actually ball bearing though. I took it apart and verified it had a ceramic ball bearing on one end and a journal and thrust bearing on the other. Good stuff!

Wow. Those look fantastic. Can you PM me where you got them from, how much they cost...basically, how I can get them, too. Would they work well for a rear-mount setup?
Don't want to hijack or anything, probably going to go over to hang out in 1964_442's thread since it looks like he's going to be going the route I'd like to follow.
