Hks T51R Or To4Z

The T51r does have a sound of its own and very sexual indeed.Rpm reckons ill hit max boost at 4000rpm so I'm kinda happy with that since the cars use will just be open track and drag days and the odd catch up with the boiz

There is no way you will hit max boost at 4k with a T51R, unless your max boost will be 5psi.

That's why he suggested I run the 4z not the 51r.all the info I've received on here has been great and very helpful in making my decision so will go with the precision equivalent to the 4z will give new technology a go.

[NYTSKY]

Even with the 4z, you will see 20 psi in the high 4k range.

If you want boost by 4k a GT30 is the turbo.

4.5k GT35

Look in the precision thread for info and results, plenty in there.

Have you considered Turbonetics at all. Bobby from JEM in his R34 build thread consulted John Skoales about turbo's, his suggestion was get ones with compressor maps. It's worth a read. A T66 ceramic roller bearing turbo with a small exhaust housing would work well.

Well "Rpm" is telling you porkies

A To4Z would not see boost anywhere close to 4,000... Especially with a 2.6...
