Any Feedback Would Be Appreciated

[aMAYESing]

So I'm currently half way through replacing a few parts on my S2 R33 Skyline, just wondering if I'm going about it all the right way/any suggestions.

This is whats already happened.

HKS Air filter.

Blitz FMIC

3" Turbo back exhaust

Full Tein coilovers

Electronic boost controller

This is whats going on at the moment.

Apexi power FC yet to be installed/tuned.

Hypergear Hiflowed RB25det turbo.

Z32 AFM.

555 Nismo sidefeed injectors.

Would I have any use in upgrading my fuel pump at this stage or will the stocko be capable?

Any insight into how much of a power increase I can expect to see if my tuner knows his stuff?

Anything else I should be considering?

Thanks, Jess.

Might as well upgrade the fuel pump (and wiring if necessary). Who knows what condition your current one is in (if standard).

The limit is clearly going to be whichever is the lesser of the capacity of the 555cc injectors (which is less than 600 engine HP) or the capacity of the turbo. Depends on which highflow it is, but probably more like <550 engine HP on that.

And hell yes. Do the fuel pump.

Thanks fellas, I'll source an aftermarket pump this arvo. Is there anything else I should be doing while i'm this far already?

New brake fluid better pads (if applicable).

I agree with getting a new pump and coils. What milage is on the motor???? I once did almost the same thing but i went with HKS 3071proS turbo kit. It was still side (low) mount and ran great. Thats where the new clutch came in handy as well. I wouldn't do another HKS turbo again due to price. But a gt30 is wonderful at that setup. Providing the engine is in good health. Good luck intrested to see how it goes:D

Yeah the hypergear highflow service has great reviews and I wont have to change any piping which won me over. Quite healthy motor roughly 140k, 160psi across all cylinders and no coolant or oil usage. Not sure what coil packs are actually in at the moment I don't think they are factory I'll post some pictures tomorrow. Thank you everyone for the feedback!
