How to get to 300hp?

[Max713]

Eventually id like to make my car into a little monster! Id like to shoot for the 300whp mark. This is my current setup:

1994 Civic EX
D16z6 swap
t3 t4 Turbo
HKS blowoff valve
Mugen 2.5" full exhaust
Stage 3 clutch with 8ld flywheel
550cc injectors
Walbro 255 fuel pump
Tuned on chrome
Independent fuel injection

What would i need to do to the motor internally to get it to 300hp? Would i need better axles, or a built tranny?

i dunno how many miles you have on it but i would rebuild you engine.. rehone walls and possible get someone to bore te cylinde walls.. it gets you a bigger displacement and more potential.. as for internals.. you got valve springs.. cam shafts.. cam gears (if you really call that internals but its sitll a good idea to get new ones if you have the money) rods good luck if you have that money.. cuz i would be broke if i just got a turbo set up.. and 300 would be pretty hard to achieve without the perfect tune.. just make sure your not pushing the limits of your internals.. if its a DD i would have your goals a little lower to maintain reliability...but of course you can turn up the boost whenever you hit the tracks or something

motors only got 45k on it... maybe 300hp is a little high, maybe ill shoot for 250whp... you think i could hit that mark with valve springs, rods, cam and cam gears? how much would that run? do we have a good vendor for this area?

i would suggest forged pistons and rods, we use CP pistons and eagle rods on most of our builds. stock sleeves, and stock head will be fine. supertech sprigns and retainers, and a zex cam wouldnt be a bad idea but not necessary for 300whp.

stock axles and transmission should be fine as well.

What is your budget first?
You might want to sell your motor and get a b16 or b18 if you can. You can hit 300hp with out going into the motor. Your looking at over 2-3g's more just to reach 300hp with a D to make it be reliable

id like to keep it under 3gs... could i hit the 300hp mark and keep it reliable with that kind of cash?
