Well right now i currently drive an acura rsx type s with full bolt on etc... blah blah blah


anyways, today more than ever i've decided that i wanted change.

Over the past few years, i've had a complete admiration for the 240s and their capabilities on and off the track. i've also wanted a rwd car for sometime now and have contiplated turbo.

now, i know you will all tell me to search and this and that, and yes i tried already, but information seems to be just too scattered about on the forums for me to have enough time (between school and work) to find all of the information i need.

So i figured, being the nice people that you are here, maybe youcould help me.

My plans for a 240sx would be to immediatly swap out the motor for turbo charged application. Most likely the popular sr20det (mainly becuase its the only one i know of from the jdm silvia)


My concerns are as follows:

I love the appearance of the 89' 240sx with its bowing taillights kinda opposite of the older honda accords (usdm s13 i believe). How ever, i do not know how long a car from 1989 will hold up in the present day as well as whats available performance wise for a car almost 20 years old.

Also, Which turbo charged motor from japan would be sufficient enough to upgrade the turbo on, make hte most power, etc....

I'd also like to turn this car into a suspension junkie as well as a track beast with an estimated rwhp goal of 300+.

I was looking into one of the later generation 240s (s14 but cant seem to find myself looking at the *** of that car. its too plain and simple) but i do like the rear of the s15 which i am not sure if it is a usdm production. are the back bumpers, trunks, taillights, and rear quarter panels between the three s models interchangable?

Are there any common problems with 240's in general as far as burning oil, crank walking, leaking, cooling issues, etc...

I really wanna switch over to nissan and i guess this will make or break my decision.

 

stick with the ka and turbo it , s15 arent legal in the us so no go ,
s13's id say go for . if you dont like the s14 then owell . i have a 98 s14 and i love it . i going to keep it as dd and probobly buy a s13 in the future for a track car

 

would the ka be the factory s13 usdm motor?


like i said, I WANT to swap it for a factory turbo motor. i dont wanna just bolt one on.

 

yea the ka is the stock usdm motor and why do want to swap it for a smaller motor ?sr20det?

 

mainly becuase the sr20det was built for a turbo. and the KA wasn't.

 

?

 

the ka wasn't built for the turbo but the sr20 come stock 205 hp but if you were to turbo the ka with stock internials your would get at least 220 hp so bar far the ka is the supiror engine plus its built tougher

 

no flaming here man. lol.

i drive a 5 speed 91' SE hatchback my self and i personally love it. if you like the pig nose style of the 89 then more power to you.

as expected of a 20 yr old car there are a few little things that you will have to fix here and there (no biggie) because after all it is 20 yrs old. lol.

as for a selection of a turbocharged engine. i would suggest the SR20DET of course. this motor to me the most reasonable price wise, maintance, aftermarket availability, and or course PERFORMANCE. a goal of 300+ rwhp is no problem with the SR.

as for the rear of all three models. not all of them are interchangable.

general problems of a 240 would have to be answered by someone else wiht more knowledge on the SR then me.

hope you get a project started and join the 240 family man, goodluck with whatever choice you make.

 

thanks for the response


as for the ka24? i believe, of course it was built tougher.... but for n/a applications, how long and how well will it hold up with a turbo. I'm looking for realiabily also. Chances are when buying a car this old, a stock motor would probably in most cases have 150-200+ thousand miles, and no moron in their right mind would turbo a motor that worn out..


Hence me buying a sr20det which was built to withstand boost, i 'd have the option of buying it with lower miles, etc...

 

yea and 300 horsepower would be no proboblem for the ka-t either
i just dont see why every body wants a sr hella lot less tourqe
and just to damn "popular"

 

the ka's are hella strong engines they'll last for ever

 

miles are miles wether it has 200+ or 50 miles r still miles im in the process of turboing a ka with my room mate and his goal is 300-350 to the wheels easily yes we have to rebuild the motor but we know it won't blow up when were done the sr in my opinon is an unrelaible motor being you have to swap it in change the harness this that and the other 1 big head ache. and i guess that makes us morons for turboing a so called "worn out" motor

what that guy said

 

well if your looking in the 89' 240. the USDM engine is the KA24E not the KA24DE which came in the the 91 - up 240s.

if you wanna go NA or turbo then i would suggest you get the KA24DE and swap that in. but yes like you said the KA wasn't built to handle a turbo, so if you decide to turbo the KA you'd have to rebuild it so it wont blow up faster. the KA its self is a pretty strong motor i'll addmit but wasn't designed to handle a turbo.

the SR20DET is the best choice for boost.

 

the sr is to over rated its just like a damn harly davidson
finally someone agres
