SR or KAT - not your typical ?

[thx247]

What I want to know are the price points for an SR vs a KAT.

Background:Frankly I don't care what engine I use, just so long as that engine can do what I ask of it.

I ask my engine to give me 350rwhp, with low enough lag (and boost threshold) that I can drive it in really twisty roads.

Question:An SR engine set is like 1800 bucks right now give or take. Building up a KAT to make 350hp in a reliable fashion is also pretty expensive. What I'm wondering is, how much cheaper would an SR be to make 350, compared to how much a KAT would be to get to 350.

From what I can see, I would have to give the KA some new rods and pistons, and maybe alittle PnP to clean it up. Headgaskets for both cars can remain stock, things like fuel injectors, pumps and turbos...all that external trash I don't care about. Both engines will need extra parts to make 350hp. I want to know if the extra price on the SR makes up for the internals it has.

In the land of performance cars, there are three factors. Performance, reliability, and cost. You can never have all 3, but you can have two. I'm willing to give up cost in search of performance and reliability.

What I'm asking may not be possible on a 350hp car, but if thats the case I guess I'll live with whatever I can get. (Still will make 350 but maybe will not get the response I want. oh well)

Thanks guys.

it wont be cheap for either...It'll be less expensive to get an Sr to 350hp.

[thx247]

now why is that? Because I would not have to build the internals to make 350 reliably?

[Daunttless]

Correct, usually KA's require a higher build up due to higher miles.

[thx247]

Lets say I have a KA with 30k on it. Does that still apply?

you would still have to do internal work. the factory pistons are known to be good for 300hp and rods about 330 from what i hear. there are guys getting 350 out of them but realibily i highly doubt it.

[thx247]

Sounds kinda like witih the KA's compression ratio I'm going to have to lower that in order to make 350 on an every day basis.

I'm going to make a price breakdown of the SR parts and the parts you need for the KA in order to get it on a comparable basis.

Known by whom? I see absolutely no reason why it can't handle the high boost with good tuning. I they are getting no detonation than it's doubtful they will blow their motor just from too much pressure. The peak cylinder pressure increases proportionatly less than the pressure ratio(boost over atmopheric pressure). I still have yet to see raw hard data regarding the strength(or weaknesses) of the KA pistons.

anybody willing to let me blow up their KA-T????:devil
