If you have the time and funds build the motor while its not in the car, that way you dont have to pull it later

You're gonna have to rebuild the engine before you drop it in the car (well i would, just to get a look on the inside). From there make your decision.

well ifi would rebuild the sr im gonna shoot for 400-500 hp...thats y im asking if i should drive it stock and biuld up y parts or just drive the ka around and buy the sr and parts...

I would rebuild, not for power but for assurance

[Lev_96_240sx]

It all depends man. If you've never driven a car more powerful than the KA then don't rebuild for power but like Pahc said, rebuild it for assurance. 4-500hp is very expensive to attain and is a bit beyond the efficiency range of the motor, that is you will have a lag monster on your hands. If you want a bit more power, shoot for 300 at the wheels and it should give you plenty of fun.

what is the car going to be used for?

i say go ahead and build the motor but leave the stock cams, injectors, turbo. get use to driving it with stock power then when you decide you want more you will have a healthy motor that can handle it.

ok ill keep this in mind ...ty u

I'd say do a compression test and if it looks fine and you're only shooting for below 13psi boost for now just leave it be. Might as well get the most out of the OE build till it dies. Unless you need it to be really reliable, but then again a badly rebuilt engine isn't reliable either.

Winner winner chicken dinner.

Why would you want to have to pull the motor again? Especially if you have the funds now and can do it right the first time.

b/c pulling the motor is easy...? i've never done a rebuild for "freshening up" purposes. just drop it in. if it's screwed up, return it. if something happens later on down the road, then fix it. be sure to buy from a reputable company and you won't have any problems just dropping it in.

i would recommend the basic maintenance stuff (ie...water pump, plugs, thermostat...etc) being swapped...but as far as a rebuild, don't waste your money unless you're just into that sort of thing.

the thing about rebuilding a motor that you've never heard run is that you create too many variables if something does go wrong (especially with the quality of a lot of machine shops out there). say you drop in your freshly built motor, and it doesn't run right...by doing the rebuild you've created any number of possible causes. just drop it in stock, get it running right...and build later.
