RB20 build up suggestion,

[C-unit]

hey, i just bought a R32 GTS-t and waiting for it to get shipped. I am planning to use the car the motorsport only as i am just a beginner. I want the car to have a solid base and last for atlesat two years for heavily abuse. I am not looking for big power, just reliability and response. the following is the parts I am looking for, feel free to give me sugguestions on wht do i need or take away.Goal: 350-380whpRB20DET-CP forged piston-RB26 rod-RB26 crank(do i need the above two?? i have been search for 2.4L stroker, does it really make a big different?? or RB20 stock rod n crank can handle that power?)-new oem bearings-new oem gasket-GT2871R (is that enough or i need GT3037??)-greddy spec M FMIC-470cc GTR injectors (or i need to go 550cc??)-walbro 255L/hr fuel pump-e manage Ultimate (i am using Mine's ECU, but it is not programmable, should i get the e-manage to plug in the Mine's ECU?? or get a stock ECU and use the e-manage as a sub comp?)-HKS mushrom intake-turbo elbow to the end will be changed. no cat.

this is so far what i have got. and is it necessary to upgrade my intake manifold for this power level? because i heard the greddy intake will decrease the response and if i dont upgarde my head, it wont make any noticeble gain. Also is rebuilding the head with new cams, springs and lifter necessary or it is just a plus?? Also do i have to upgrade my oilpump and rad?? i have search many forum and most i have got is to get rid of the 20 and get a 25..this is what i m not going to do because the car comes with a 20 and i want to stick with it rather than spend the money n get a used motor. please help me out. thanks in advance

look on skylinesaustralia.com for a few indepth rb20 threads including what kind of setup you need for that kind of power.also if you search i posted my build and what mods i did for what reasons to the rb20, it should be 500bhp capable when it runs again.

I 2nd sklyines downunder, they have tips for road racing on how to setup the motor n stuff so you don't blow it to bits.

470s should be big enough. A general rule of thumb is 1cc/min of injector is good for 1 flywheel hp in a 6.

to make 380-400whp 440cc injectors are not large enough you will need atleast 550's to keep duty cycles in a somewhat reasonable range.
