250 at the crank of a 5sfe - cams needed???, All I need are good cams. Options

[lipweb]

Ok. I've looked over this site and either it's not listed or I don't know how to find the information. I've got a master mechanic that just built my brothers 90 eagle talon tsi AWD that's pushing 710 hp. This thing is scary fast. That's beside the point.

He's very good. Works on Supras, Nissan Zs, Lotus elise, cobra shelby, Acura RSX-S, etc... Mostly turbo, but quite a bit of NA too. This guy is good and his shop is amazing!

This mechanic has looked over my car and has estimated a price to build up my 5sfe NA.

approximately 250 on the crank. Definitely not 250 whp. I don't even think that is do-able with this motor.

First mods I will need are breathing mods , IHE god quality stuff (e-bay parts wont do it ) problem is though all the good quality things are going to be hard to source as the car is 11 years old and some stuff has been discontinued .

Next is porting and polishing the head and getting some oversized valves and shaving it to bump the compression . But none of this is much good if I cant find a more aggressive cam to make use of the extra flow .

So these are my starting points.

I have a guy who'll do the god quality header for me. $600 all custom

Now here's the BIG QUESTION - Where do I find stage 1 cams for this motor? They MUST be god quality to handle what he's going to do. Do I have to go custom? If so who can do them?

He'll do all the head work . Ballpark for headwork with new valves , springs , retainers, cut seats most likely replace the guides and port, polish and shave is about $2000 ( that does not include removal or installation ).

I don't want turbo. I know turbo makes a hell of a lot more sense, but then it wouldn't be an 5sfe.

Any help is appreciated!

its not totally uncharted. its been done before by the 5th gen guys. they all came to the conclusion that its just not worth it. youll spend thousands, and end up with 20-30 hp more then what you had. the 5sfe will never put out 250 hp in NA form.

you need some form of forced induction to reach that goal. if you want to stay NA then look into the 1mzfe swap like was mentioned.

Do you know any of these 5th gen guys? Or, where I can find info about the outcome of their NA projects? I'll do some research on the 1mzfe and consider it. Thanks.
