My apologies if this sounds off but it was a little tough to understand what you are asking. If your goal is 650 WHP the GT-K 550 MIGHT get you there but it will be a stretch I think. The GT-K 650 would definitely get you there but with the T4 turbine you might have some lag on 2L of displacement and it also has a larger compressor (HP66) which might also negatively affect your spool up times. My best suggestion is to run the GT-K 550. It is a larger T3 and the GTK 61 compressor should flow for your intended goals.

thank you for your reponce

innovative has more advantage .

F2 F267 series
because it is smaller than the gtk550
101mm (4.0?) Compressor inlet/63mm (2.5?) is it has the performance of a gtk 650.

Im sure both are very competent turbos, and I have used Innovative in the past, with good results.

BUT, before you buy an Innovative unit, do consider customer support.

We recently tried to get 2 units rebuilt recently, a T70 and a T60-1. The rebuilder could not get any parts from Innovative. They could not get in contact with them at all.
So they supplied us with a new Turbonetics core instead.

I believe Innovative are having problems, or some re-structuring at the minute, and it is affecting their ability to supply, and communication with customers.

ie. Nobody can get in touch with them !!!!!!!!!

If it was me, Id choose Turbonetics for these reasons alone

Well i can understand that you couldn`t get in touch with ITS...arent they have been shut down?

My previous ITS dealer says he is negotiating about new wastegates and dual-ballbearing because ITS are no more exicting.

Innovative Turbo Systems are no longer in business, and Ive heard of a few people who have lost money with them. We were very close to losing a lot of money ousrselves. In fact, we pretty much did, seeing as a couple of old units couldnt be repaired due to no access to parts.

One of their former people started up a new Business, Exile Turbo's or something similar.

I guess the old adage, "Caveat Emptor" should apply. Buyer beware.
