Turbo Alternatives

[sc00bs]

Hi Guys

I am looking for some suggestions for alternative turbo's for my MY06 Spec C Type RA. I find that I am unable to hold boost towards the top of the rev range and am considering some sort of bolt on replacement to be able to hold boost a bit higher up in the rev range.

I was considering an HKS GT2835 but after speaking to a few people found out that they have been very unreliable in SA, two were imported and both of them blew with bearing issues.

Anybody got any other suggestions?

Thanks

Scoobs a Hybrid twinscroll with 2bar actuator like what I have on my type RA would be what your after opens up the midrange/top end breathing doesnt run out of puff hits 1.6 bar.

Hi Gus

Thanks for the suggestions, that sounds about right.

I assume you changed the the compressor wheel?
What did you change it too?
Also, did your bottom end suffer a lot?
Have you got a before and after dyno?

Any idea what the RA-R has on it, is it the same turbo as the RA?

John I have just picked up this thread the reason I changed to a hybrid garrett cored twinscroll was due to what I said earlier its the next one up from what Shaun on scoobynet had on his before he went cosworth 2.5 it spools up about 100+200 revs later than the normal vf36 no lag and runs cleanly right to 8,000.Im away this weekend and will post up the graphs. On 98 ron v power before it was running 360 bhp after with the new turbo on its running 415 bhp/398 ft
