ok i know this is a stupid question for the rest of you but i am kind of confused on the issue, but what motor does a stock 240sx have, does it have a KA24DE engine?

 

89-90 KA24E (SOHC)
91-98 KA24DE (DOHC)

 

thanks for clearing that up for me, i appreciate it

 

I could of sworn it went something like this:

89 - 90 ca24de

91 - 98 ka24de

I could be wrong, but i have seen people say that.

And while'll we're at it, whats the difference between SOHC and DOHC? Always wanted to know... Thanks!

 

well an SOHC engine means the engine has a single over head cam(SOHC). And a DOHC has dual overhead cams. if you want an explanation to what the difference is check out this

Thanks man! I feel like I've just gotten more education from this instead of the 15 years in school and still going, LOL!! hahaha.

Also what about the

ca24e and ka24e?

 

there's a ca24de?

89-90 240sx: KA24E
91-98 240sx: KA24DE
180sx (unsure of years): CA18DET or SR20DET

Silvia/200SX J's or Q's: SR20DE
Silvia/200SX K's: SR20DET

would i be better off getting a 240 with the ka20det motor and modifying that, or should i get one with an sr20det motor and modifying that?

 

ka24de-t more power. there is no replacement for displacement, in that case get into a rb26dett!!!!!

 

how much power could i get out of a ka24de on the stock block?

 

350hp no sweat, if u build it you could be looking at 450 hp

 

I heard from some dude that turboing your KA can blow out your sidewalls?

 

Well I guess if you reach that stage (450hp) then why not start on next project; RB25DET(T) or RB26DETT (You will need a rb25 tranny for this).

I think 450 hp is enough for your daily driven or drifting car. Otherwise get the rb to start yourself off. Though getting a rb26 will cost you alot more money then ka and a bit more then rb25. So I recommand RB25DET(T).

- My Two Cents

 

450 horsepower is enough for street racing. It would eat up most hondas and DSMs, plus alot of mucle cars.
