Max power on following parts

[sr1via]

Hi All,

Very sorry if this has been covered already many many times.
Ive done a search and found most info im after but basically my question is what power are the following parts rated to :

Stock Redtop injectors
T28R S15 Turbo
Z32AFM
Stock Cast manifold

Im importing a Onevia with Redtop SR20DET. Ive started buying up parts way early as car wont arrive till august and my aim power wise is 300bhp and similar torque. Ive had RB25DET R33 for 7 years so im new to SR's.
I only had 320bhp in my heavy r33 so 300 in a silvia will be plenty to have fun.

Cheers in advance and sorry if this has been covered already

limiting factor will be the injectors i reckon 280 tops

S15 T28R Turbo is rated to about 320bhp

Mint so just injectors and fuel pump left to buy as I have nistune aswell.

Is there any thing I need to look out for in terms of common faults on redtops?

Ive read about oil pickup so ive brought black top uk sr one.
Are the injectors on uk black and redtop sr the same set up as the inlet manis look different from pics!?

The standard Blacktop SR injectors are 370cc's so I would imagine they must be the same in the redtop.

Also yes the inlet manifold on the redtop and blacktop are different looks wise, not sure if one is considered better than the other in any way.

As for redtop engine faults I wouldn't know tbh mate as I don't have one. For starters at least you don't have VVT to worry about like on the blacktop lol.

probably best if you speak to someone like Horsham Developments or any of the other popular nissan tuners

I'm gonna run my s14 at 300bhp but I'm gonna use the 480cc injectors from an s15 as the standard injectors I know will defo be running their max duty at 300bhp

280-300bhp if you're lucky. The T28R doesn't flow any more than the S14 T28

280-300 will be fine for me I think.
Cheers for the info guys
