If I where to go fi what should I look at for about 350hp?

[Bimmer_man]

I have been talking to my machine shop guy and he wanted to know weather I will be going fi or keeping it n/a. The more I read about this engine the more I love it. I have a m30 at the shop it's going to be punched out and new forged Paul burk pistons with a s38 itb system and it's getting a cop set up. All run on megasquirt. So if I wanted to go fi what psi should I look at? All my friends are saying just get a sti turbo and call it a day lol.

Do you mean how much psi is going to get you 350hp?
Like 12 or something.

[Bimmer_man]

Yeah I should have clarified better.

[navytapaul]

+1 12psi seems to be about right for that range.

go NA 350bhp

[kylelauffer]

Is that a joke?

No.

Much easier/cheaper to get 350 FI'd HP than NA'd HP

Is that a joke?

i am talking bhp not whp

proper CR, proper headwork, cam, ITB tuned intake, tuned exhaust and standalone will do it. its actually a better proposition than a M5x, S5x IMO. The head will flow 260CFM when sorted which is about the same as a S50B32 largely due to the big bore and valves. There are a few stroker options to so you can have the torque that the 24V guys would only dream of.

[kylelauffer]

They are great flowing heads. But n.a. you will never be satisfied with the power after spending that much money. Go for it. Good luck

[digger]

he is already planning standalone with forged pistons, S38 throttle bodies so he is not far away. one of Paul Burkes CNC heads/ cam with a nice exhaust and GTG

The cars were powered by a range of inline 4-cylinder and inline 6-cylinder engines. The E30 BMW M3 was fitted with a high-revving 4-cylinder petrol engine (BMW S14) which produced 175 kW (238 PS; 235 hp) in its final European-only iteration.
