ok so here is the storry

i am planning on rebuilding my engine and i am going after 235 HP N/A

F2 pistons = 12.5:1
F2 Rods
Ranger Crank
Lightweight flywheel + clutch
Valves springs (going after 8000 rpm) retainers, keepers etc no porting tho
exhaust + headers
intake manifold from cosworth

For the first time i will run on the stock ecu after that i plan on going to microtech standalone so i can increase the rpm, and remove teh vvt and replace the cams with the duratec cams

now this is my plan. is it feasible?

I'm sure anything is feasible with the right amount of money...

I dont know if it will make 235 though?

 

[hate_romania]

about how much? any ideas?

 

[prototype99]

Just a ball park I would guess around $4-5K + labor if you are not going to be doing all the work. Either way you will not make 235hp... Maybe 200 if that. Turbo if for that much money and it will have about 235 (think that is what the custom turbo kits are putting out). Someone correct me if I am wrong but I dont think I am.

 

[luisdc]

Thats correct

Why no port work? The head will be off and disassembled to install the valve springs and retainers. It would be easy to do a basic bowl blend and manifold match at that time.

A bigger/optimzed throttle body may help too if you are going to 8,000 rpm, though I gather the MAF is the real restriction on intake flow in these engines. Still, anything you can do to free up air flow will help.

cosworth motors make 250 crank hp.

and they have 9k rpm rev limit...
