First off, I dont know what section this belongs in sense it has to do with Evo9 parts, but on a 240sx. Please move if in wrong section. Thanks


So, my buddy is a 240sx nut, he own like 4 first gen 240's , and was thinking about putting a Evo9 turbo on his DOHC 240sx. He knows alot about 240's and is custom making the manifold himself so it should fit. My idea is that if he can tune it right it should be a pretty awesome set up. I imagine that the 2.4L should spool that turbo extremely fast. I was just wondering if any of you had an opinion on the set up, or have had any first hand experiences. Any feed back would be awesome, good or bad. I'm going to be giving him a hand so if you guys are interested then i'll update as it goes. thanks in advance!

 

that may work but it depends on how much boost does he plan to run. if he is planning to run below 18psi then i think an evo 9 turbo may be enough.

 

waSte of time...owned a bunch of 240s...

 

Wait wait wait.. you just said put a turbo on the KA. LOL

SR > KA

Unless your AMS or something

 

I have to dissagree, the big thing with 240's is to turbo KA's. On the 240sx forums, they have a whole catagorie just for turbo KA's. Granted, it was thought to be impossible for just any regular 240sx owner, but I've noticed with in the last year that alot of typical 240sx owners do it with out any major problems. Some people are argueing that the turbo KA my be better then a SR, because of the extra displacement, but right know it still is all opinion.

 

my friend has the 9 turbo on an srt 4 soo go for it anything is possible

 

He wants to start between 15 and 20psi and then go from there. He wants to see how happy he'll be with a stock 9 turbo first, but if he is going to go then he's going to upgrade it to either a green or a red (that would be cool)

As a track car, what kind of psi do you think would be best. you think anything over 18psi would would have lag problems or do you have other concerns?

 

not completely true.....ka's have a 25% increase in displacement which limits its rev limit to 6000 whereas the sr can rev to 7500. the ka's create more low end torque than the sr20's but then again the sr20's make up for it by being able to rev out higher. I guess you could use a lower gear ratio and make up for the low end torque since the kas is engine torque rather than gear torque. so it really just depends on preference....

KA=SR

But if he's got 4 then he might as well do a KA-T an Sr20 an RB26 and an ls1

 

LOL Thats because everyone on those 240 forums is broke and putting a turbo on the KA is the cheapest solution. I have a '98 240 and look on some of those forums all the time. There's a handful of clean cars and the rest are complete and utter garbage. Anyway, to answer your original question an Evo 9 turbo would be sick as long as the mani is good.

 

There are better options out there

 

Exactly my point. Your turbo is going to like 7500rpm a lot more than 6000rpm.

 

Meh but a evo9 turbo on a 2.4 doesn't really need to rev way out cause itl'll run out of steam.....

 

My mom has her my stock evo 8 turbo in her Camry so yeah go for it. Holla

 

So you could say that the evo9 turbo is a perfect canidate far a Turbo KA project. I cant believe I never thought about that before. Thanks for that observation, I was starting to loose faith in the KA as soon as I realized how much lower it revs.

 

Jesus... the things people say
