Next Step Upgrade

[CTM508]

My current setting:

stock RB25DET stock engine

HKS 2535

stock injectors

stock AFM

What should I do for next step to increase power and tor?

Engine or injectors?

now is 200rwkw focusing tor on 11.3psi

Thank all suggestion first

ecu

[CTM508]

Sorry for miss information

I used E-mange

[N1GTR]

FMIC?

[2LV8ETR]

Exhaust, fuel pump, FMIC, filter, crank up boost.

[CTM508]

I have full turbo back exhaust, high flow fuel pump with adjust regulator, FMIC, Pod filter, EVC boost controller with strong actuator, Twin power with D2~

I want to boost up to 14psi in safe condition

what should I do?

change injectors or change engine parts such as valve spring, gasket to change ratio

If I want to change Cam, any suggestion for that? Can I change exhaust cam only like EX256 with adjust pulley?

because Intake side has NVCS......

[joeyjoejoejuniorshabadoo]

you will want injectors to go over 230rwkw or so

you can get yours highflowed, or even just push harder on the reg, but the best idea is to get bigger ones.

for that turbo, look for a set of 2nd hand s15 injectors

You wont need to touch anything engine wise.

As has been said, get yourself some injectors, wind up the boost and go for a tune.

[CTM508]

Thank for all suggestions firstly~

If I use Z32 fuel filter and adjust regulator, will it increase the fuel and flow better~

Except that, I plan to change Z32 AFM as I had one already~

Now set at 14psi(1Bar) or set higher to get 250KW

Another question, how about to change Engine Valve to let engine work better

Is it a good protection to boost up stable?

Then, I can change exhaust cam gear adjust 1degree to start turbo early

Hope one can answer my question~

If you open up the engine you are in for the big money and changing one valve won't do any benefit. Your stock ones should be alright.

Get ecu, injectors, z32 maf and go to a shop to tune the car.

Don't worry about the head for the time being. Big money once you start playing with that, especially if you can't do the work yourself.

You might have to look at changing your clutch too if your still spinning the stocker

If you set the rail pressure higher, then yes, you can get a bit more out of the injectors, but you are going to have to re-tune everything.

I can't understand the rest of what you typed. Not being a dick, but english is your second language, right?

[CTM508]

Thank~ English is my second language......

If I want to start turbo early in low rpm, will adjustable exhaust cam gear help this area?

[PM-R33]

It can do, but it also might not. For that size turbo, you don't need to worry about trying to make it spool up earlier as it will be responsive to begin with and any gains you get in response will be minimum.

wind up the boost to 18PSI, get new injectors, get a Z32 AFM, chuck that FRP in the bin, get a new tune
