I am not a NIssan guy. BUT i would agree with boosting the stock 2.4L, byt the time you invest for the JDM swap and build the motor you could have built 2 2.4L motors.

Kinda on the same subject: I read somewhere that the stock motr in the 240sx didnt like mad boost even if built something like the main caps would blow apart? I dontknow if that is true. im sure arp studs would fix that. also i would only boost the DOHC 240 motors. not the single. Then again i could be talking out of my ***...sorry.

I believe one of the guys around here is boosting a RB25 in his 240 and making some good power...I'm not really into nissans so i'm not 1005 sure but i think those motors were fairly cheap...

thanks for the info and this isnt actually my car it is my friends and i had to talk him into keeping the ka24 and turboing it. but we were just wondering about the twin turbo thing. it dosent matter my car will still be faster

ka24de + being built + proper management + large turbo + manifold + oil lines = a ---- load

sr20det swap = 2,000 in my area... thats cheaper then any built ka24de + proper everything else... the sr20det with boost set at 14psi on stock everything will give you more then enough joy to be satisifed n kno it will last because the motors made for it. ka24de's are nice motors for boost when u got some doe to spend.

if i was to boost a ka it would be the sohc. from what ive seen, it creates some really really good power.

rb25det fairly cheap?

3500 + shipping + gettin it to fit = a butt load... fun when its done though...

Im not knocking the SR in any way I just find alot of these guys are obsessed with JDM and if its not from Japan it must be junk.Basically the same as some of the Honda Tech crew.I actually am doing a SR swap for a local guy in about a month.I was trying to convince him to go K24 turbo in his car but he wont listen to me.You are right though the SR is cheaper as even when you factor in the parts for swapping like gaskets,new waterpump etc etc the cost would have been quite a bit more to do a proper K24 turbo.Is there any little things I should look out for when doing his swap as I have not done a Nissan swap before.I gave him a list of odds and ends to replace as now is the time to do seals,clutch, etc while its out rather than later when it's installed.

Lol, you can get RB25's for way cheaper than that, your paying for a front clip in that auction. My friend got his RB25 and did the entire swap for under $3,000. Stock boost with absolutely nothing done but just dropping in the RB25 it ran a 12.5 in regular street tires. IMO an RB25 is the only way to go for a 240.

keep what you have stock and boost it, should be around the same price as a hmt kit for a honda, the nissian ecu's r chippable as well arnt they?

turboDA6

chippable for around 700 dollars... for JWT ecu..

only things you need to look out for on the swap are the obvious. n that weird tube that comes off the downpipe will hit the steering rod. you have to take it off from what i hear. i changed my dp elbow so it didn't have that anymore. and ur wiring. theres some pin changes needed for ur cluster to opporate.

and for the rb25 swap. u basically need the clip cuz of the cross member unless you buy some 1200 dollar mounts for the 240sx cross member, + drive shaft + all ur wiring n so forth. i wish i could afford an rb25, i woulda done it but if i go that high might as well do the rb26

Reddy

omg are you serious? Mounts do not cost $1200, you can do wiring yourself, its not that hard and any local shop can cut your driveshaft to size its not like its some exotic process. Your trying to make a simple swap sound complicated and expensive when its really not.

turboDA6

all im saying is if a rb25 swap was that simple n cheap then everyone would be doing it...
