ok i amit nissans are not bad cars with a little TLC can eat a honda. i know everything there is to know about hondas and did many swaps.. but when my friend said he wanted a 240sx POS i knew that he can drop in some flavor of a JDM nissan engine in it.. i need some one to really give me a crash course in engine code and models .. what can be droped in with ease and not.. i come to understand S14 is just a generation number for the 95-98 and thats the car my friend wants to get..
buget wise he can afford spending up to $3000 on a used engine and tranny not counting changing what has to be done before you drop it in (timming belts,, seals and stuff)..
he would be happy with the stock turbo which he can upgrade at a later time..
what is a SR and RB? what is a fairlady and bluebird? difference in red and black tops.. thanks in advance

Way to cross over from the darkside....j/k...
To answer your question, the most common JDM swap for the 240 is the ol' SR20DET drop in. The SR20DET is the motor that comes in the Silvia, the JDM version of the 240SX. The code decipherd= SR series motor, 2.0L, DOHC, EFI, turbocharged. I believe it uses the T25 turbo. Anyway, I believe the transmissions will bolt up, but you will probably need a mounting kit to allow for the extra space required for the turbo and difference in size. You'll be swapping out a KA24DE motor which is a 2.4L DOHC fuel injected motor at about 144hp. There are plenty of kits availble for this swap; it's pretty common. Search for "silvia conversion" for info. The RB motor or RB26DETT will not be able to swap into the 240 without extreme re fabbing of the engine compartment (basically not possible). It's the motor from the coveted Skyline: RB series, 2.6L, DOHC, EFI, twin t28 turbos. The Bluebird is the JDM version of a Stanza or Altima depending on the year and I think they have CA series turbo motors. A Gloria is a larger four door JDM like the maxima...proabably runs a VQ35DET nowadays, but I'm not sure. The fairlday is the JDM Z car series. They are designated with chassis codes like Z32 and Z33. The 300ZX here was equivalent to the Z32 Fairlady and had a VG30DETT motor. Now, the Z33 in Japan is cousins with the 350Z in america and they both share a VQ 3.5L motor (also used in the Infiniti G35). Your best bet is an S14 silvia SR20DET motor to drop in. $3000 should cover parts so I hear. If your interested in more in depth motor and chassis codes let me know, i have a list around here somewhere.

i beleive that the s14 sr20det came with a t28 turbo...there is two engines from the skyline you could drop in the RB20DET and the massive RB25DET.... look here for answers

I never knew they made a 2.5 liter...wasn't the RB20DET the first skyline motor (1989)? I wonder if the OBD stuff would matter or if any of the electronics would have trouble being mated. I believe they had an N/A version (RB20DE) too.
i forgot to mention the CA18DET is also another engine that can be swapped into the 240. I dunno if there was a a N/A RB engine i would have to look around to say yes or no first
yes i have seen a couple of those.. MUCHO power..
i was referring to BeEleven when he said "i never knew they made a 2.5liter..."
sorry for the confusion

Actually, the first Skyline was built in the 1950's by the Prince Motorcar Company that Nissan assimilated in the 1960's and has been built ever since.Remember also that there were several different levels of Skyline-even a 4 door sedan.The RB26DETT was also used in the Staega ,I believe, which was a 4 door station wagon.I am unsure when the RB series engines were introduced though.

no problem vsp3c
if i was to build up a SR20 i would get the internals beef'd up and slap on a really big HKS turbo........ skyline who?
-red top SR20DET's are from S13's. black tops are from S14 & 15's. there are also black tops in 180SX RPS13's. they are the same as red top S13, not S14. S13's make 202hp; S14's=217hp; S15=247hp. an S13 would be best value @ about $2000+install. the rest are kinda expensive and have little benefit; S14's just run the T25 harder and S15's have a T28, still pretty small; and it'll cost twice as much. the six speed also makes the S15 install VERY tricky. their only disadvantage is their aluminum block won't hold more than 450hp for long.
-the RB25DET (skyline GT-S, not GT-R) isn't too hard a swap, but is a little more involved. but with a whole front clip you should be ok . they are quite a bit heavier, require more work for install (though not too much custom, contrary to popular belief) and cost about $3500 on their own, but have way more potential than anyone could realistically use on the street.
-a good compromise is the KA24DE (stock engine). surprised? with a $3000 turbo kit you'll have about 250hp and an easier install than either the SR or RB. plus a T04 and FMIC, so you won't need to spend $ on them later. all you need after that is fuel & engine management for 300hp+. then build the internals and it'll hold 450hp+ easily. cheap compared to an SR swap bc you don't need a swap, a bigger turbo, or a new intercooler. plus it won't leave you wearing your block. the downside? hmm...i don't know...it's not "JDM" i guess. but i say screw JDM, i want as much power as i can get for as little money as i can spend.

i personally like the SR20DET phase2motortrend race car is pushing 474hp on 25psi with the stock bottom end.. they are going for 500hp pretty soon *drool* anyways, the s13 sr20's have T25 turbos on them. the s14 and s15 sr20's have T28 turbos on them. the S14 has a T28 ball bearing but the S15 has a T28 Ball Bearing with a cast divider wall between turbocharger exhaust flow turbine and turbocharger exhaust actuator wastegate flapper
i'm don't want to start another hositle discussion/argument, but this is what i would do.
option 1: get the sr20det
option 2: mod the ka24de
option 3: get the rb20det or rb25det
even though the rb makes a lot of power, it would be my last option.. just my 2 pennies
