I really don't mean to sound like a broken record. but anyway, if this turbo is alot like the stock CA, what would happen if you introduced the DE cam into it. So this T28 + DE cam = ...

The specs PFB posted show the Compressor A/R to 0.60, but the description for these turbos show that it is 0.42?? Am I missing something here?

I would sacrifice low end torque for mid to top any day

Different strokes, I would far rather have nice low and mid range because this is where I spend most of my time when driving. I floor my car maybe once a week but drive it everyday, everyday drivability is farmore important to me

More overlap more reversion but Mid-range should be greatly improved. I love the DE cam It made a huge dif on my ride

The R@D I have done on the GT-R turbo shows there are 6 Different types might be more RB will know.

Most are just slight changes from model to model like the R32 RB26DETT to the R33 RB26DETT and so on the Comp housing Doesn’t play a a large role in the Flow rate.

If it will improve the response on my SX then I'm happy.

I read something similar last night...

Hmm I thought the GTr's had ball bearing turbos...

Only ball bearing on R34 GTR RB26(if they break, its not rebuildable). These turbo's will give you less lag with real quick responce, the trade off is less top end power. Should be almost no lag on CA18.

Brilliant.

One word

Supercharger.

There’s no lag and no good efficiency unless properly sized
