Hey whats up. I drive a 96 240sx, and im ready to add some forced induction to the stock motor. Only problem is that all 240sx forums primarily deal with SR20DET motors and how they break down all the time and /or never get AC to run along with the motor, etc etc, blah blah....

I figure id talk to you guys for a while about turboing my 240SX.....

 

my buddies SR20DET runs 12.14@114 on street tires and drives it when its not raining, he just got back from the beach with it(7 hour trip) with out any problems. i dont think the sr20det is the problem i think the people that are doing the swaps are. i know whn im done with my integra(which will more than likely be never) i'll get a nissan next.

 

the sr20's are fine engines for boost, as long as they are done right.... i have been doing alot of reserch on the 240sx becuase i am goin to buy one and make it a 180sx D1 syle drift car... although i mihgt be keeping the original KA(lat of money) engine i plan to make 300wrhp with it.. if u have any Q. i will be hapy to try answer them... and if i dont know im sure someone hear does.....

 

ive seen those motors kicks some serious *** at the track. my buddy was gonna get that swapped into his car but the only thing that scared him was the fact that those motors have at least ten years of age on them. if you are that worried about the motor your cheapest route would be to rebuild it with oem parts. i heard that the oem parts could withstand up to 500 hp easy, but then again i just heard that and dont know if its true.

 

how come no one talks about the ca18det? its an equally capable motor and you can use m any parts from the domestically available ca18de from it

my friend has one and it rips and besides you can get ca swaps for dirt cheap

 

thats what my friend is doing to his 240 ca18det

 

u might also want to look into a rb25det swap...motor is a lil more expensive but it will blow away the sr20..in stock form anyway...ohh yea its from a skyline gts..unfortunatly the rb26 wont fit unless u make a custon steering rack or u single turbo it(i know there was a few more mods that needed to be done to work but thats the big one)

 

the swap is very straight forward when u have an entire front clip to work with.....u have all the necessary parts right in front of u. the stock DET (stock turbo, boost setting, fuel, etc) will pass emissions just fine too. jons car has never had any driveability problems at all....except for the clutch incident





i think this may have been the source of the problem



edit:
cost of swap:
-89 240sx coupe no motor = $500.00
-S13 front clip with fenders/hood= $~$3400.00
-running car = ~$4500.00

 

Don't know if this has been said, I didn't look over the thread. Look into the ca18det, much stronger block.

 

when i do my nissan it will be an sr20. ca18 can kiss my intercooler.

 

the sr20 is a good engine...but if you go over 9000 rpm, or use high lift cams...the rocker arm assembly can fly off...you have to get rocker caps, and that helps a lot

thats where most of the failures i've seen come from...well, that and the fact that it is a boosted engine..and they take time and paitence to keep running good.

 

I think the original person who posted wants people to tell him about turboing his stock KA motor and not more info on the sr20.

 

yeah I did that in my wife's sr20de sentra and it went to 9000 rpms (supposed to go into 4th but went to 2nd) and it broke the rocker arms. good thing they covered it under warranty.

 

i'd have to disagree w/ the statement that sr20's suck. here's a pic of a friends 240sx that had a sr20det w/ only intercooler, blow off valve, clutch and flywheel, and a 50 shot on a totally stock motor and ran an 11.6 w/ a 1.49 60' time w/ some 24" slicks, no joke. This thing hooks and the 50 shot spools it pretty fast but he's only boosting 12psi w/ stock turbo and manifold(it wont go any higher). It's registered and he drives it a few times a week w/ no problems. (40 mile drives on the freeway every weekend for races)



and if that's not good enough than go with a rb26dett(sorry to tell you guys the rumors of it not being possible is false) It is in my friends car running great. It is rwd w/ a rb25 tranny and an r33 skyline rearend that bolted in w/ factory driveline. It remains twin turbo, no cutting or welding was required in the engine bay or for mounts, a stock s15 crossmember was used and bolted in and onto the motor. For now he's using stock intercooler(skyline) piping and it fits decent. The only thing that needs work is the downpipes, it will be hard to do 3" but 2.5" won't be bad to do but it's kinda small. You can't see the turbo's themselves but they are both there, you can see the two mass air sensors and two blowoff valves as well as the stock intercooler piping collector on top next to the valve cover.

 

damn thats a nice ride havok!
thats what myf riend is going to do after he sells his c18det s13, now i wonder if fullrace can come up with a equal length manifold for an rb25...HMMMMMMM

 

it is almost the same as the supra manifold we just designed, except backwards

 

hey geoff.
Have you guys done any sr20 manifolds? i'm planning on making one for the car pictured above w/ a big t3 turbo on there. Just wondering what you've come up with if anything.

 

ya there are a few sr20 manifolds floating around from full-race. this is the one on my personal car.

 

i must have one..

 

I sold my 2000si to do a siliva, i have ten grand total in the car, Since i have put the motor in i have yet to touch the enigne. Runs just like a stock car. I rran it at the track with some 4 year old drag radials and hit a 8.6 in the 8th with just a exhaust and 9psi of boost. Oh my car gets about 100miles of work driving a week, never had a problem. very fun car. heres pics

Not the information you want to hear, but we have NO problems getting SR's to run strong, reliably, and air conditioning? Yeah, we figured that out too, along with cruise control and all the other goodies that a complete car should have. I think you are consulting the wrong people personally... if we can help you we are but a few hours away.

 

My friend here locally has a shop and a S13 w/SR20 that has had no problems at all...I have driven the car also and its great....he now has 469whp still on a stock bottom end...here is his dyno sheet...

 

you can either buy a turbo kit around $4k or piece together one yourself. i'm currently working on a KAT and i'm going with a t3/t04e, 65# top feed injectors, haltec e6k standalone, blah blah blah. there's a guy here that made 509whp on a built KA with a T66. he should be looking at close to 600whp once he work out some bugs.

I'm not sure if thats true. There is a reason why they only used the CA18det for a couple of years and switched to the sr20. Even though it is still called a 180sx in japan. There was a post on here awhile ago with a guy who had a s13 running high 10's with around 400rwhp and the stock block.

 

the car pictured above ran 11.6 w/ stock head and stock block, stock turbo and manifold, stock injectors and 12psi w/ a 50 shot. it's got a built head now, w/ a few other little things like a hks headgasket and a manifold and big turbo in the works. should be 10's no problem on stock block w/ about 18 psi.
