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!

It seems your pretty set on building an NA motor, but judging from what people are saying, the 5sfe doesnt seem worth it. Why dont you look into swapping in a 3sge motor? or a beams 3sge? i think the beams has around 170 or 180hp so you would already be close to 250hp. it sounds like you have the money, so if i were you, id grab a hold of one and build that one instead... Youd be closer to your goal. Just a thought, unless you really think you could pioneer something inovative enough to squeeze some power outa the 5s. Good luck!







by the way i second Itchy B on Webcam. I used to work at a motorcycle shop before and a lot of our customers would get custom grinds on their stock cams for high hp apps.
