>>>> what do i need to do to my motor to make it stand 350+hp<<

[skywise]

Okay, so i have a 91 240sx and the motor knocks on it i think i need new bearings. I have to rebuild the motor anyway and have about 2 g's to play with but the turbo right now isnt my concern. I just want to make my motor strong enough to handle 350+ hp dont know if i can but thats my goal. Can anyone tell me what i should buy parts wise? and what i need to do to the motor? And if i cant make it strong enough with 2 g's can you tell me how much hp i can make it stand. and how much more i would need to make it stand that much

Also, I dont really know what the t25 or t3/t4 stuff means. And when you look at turbo kit ads and it says for 300-400 hp motors. does that mean that it would give your car around that much if it can handle it for it runs best with motors that already have 300-400 HP?

can someone please explain this stuff to me it would help me out alot!!!

Many people have gotten 350whp on stock internals.

Replace your rod bearings and inspect your rods for any potential damage, (if they are damaged, or showing signs of potential fracture or excessive wear, replace them) check your pistons for cracks or damage and replace your piston rings for sure.

I would go ahead and do a whole head gasket set as well. Valve stem seals, manifold gaskets, and head gasket.

Then you should be good. I also wouldnt jump to 350whp , if your asking such questions its just going to create problems.

And no...a given turbo isnt going to give you a SET number of horsepower. The amount of power you make depends on how much PSI of boost your turbo makes, and how much actual air its flowing at that pressure and thats not directly related to the turbo size, but rather what you set the wastegate for.

you control the amount of power, by controlling the amount of boost. And thats what a Waste gate is for. A wastegate is a mechanism that you set to open when your turbo starts making a certain pressure. When it does, it will open and bleed off any excess pressure so it puts a limit on the amount of boost.

Dont confuse it with a blow off valve. Thats different.

but t25 and stuff ,thats just a designation for a particular turbo.

so after i put the new seals and bearing in and inspect everything i should be alright with putting on a bolt on turbo kit? what kind of turbo kit should i buy to make that type of hp?

[skywise]

and do you think that i would be able to do all that with the amount of money that i have? minus the turbo and having it done professionally

I don't have a KA-T but I'm pretty certain that that budget won't get you to 350.

well i get alot of money thats just what i have at the moment so i want to do wat i can now. but how much hp do you think i can get with 2500 or so

????????

[redtop91]

I don't have a KA-T

Maybe the KA forum would be able to give you a better estimate. I'd say close to 300.

and when it comes to t25 or t3 t4 which one of those would be capable of making the most boost

[redtop91]

The T25 is only good for 14 psi. T3/T4's are far more efficient than the T25.
