LS1 in a 240sx.....240ss!!!!
i'm looking into this swap as well, i'm thinking if i can pull it off for 8k its totally worth it. i'd need at least 8k to get a 350-400 hp sr20 into my car, with a ls1, at least my 240 will be street legal =)
btw, how far does the LS1 rev up to? 6 or 7 k?
A hydraulic cammed LS1 can rev to 7k depending on cam/springs.
lime creek motorsport's twin turbo lt1 240sx (running in the 10s) broke its stock R200 after a while but switched to a RS200 from a skyline gt-r.
the main concerns i have with this swap are:
1) heat, apparently the 240sx front end isn't designed to provide cooling for a V8 (duh), so heating for both the engine bay and passenger compartment (since you won't be getting ac with the swap) may be a major concern.
2) if power steering still fits/works with the V8, lime creek took out power steering because its mainly a drag car. Apparently the car doesn't necessarily handle worse with the V8 since the weight gain is minimal, but the lack of power steering will really hamper turning and “handling”. My car is a drift car, so turning and rapid steering is pretty crucial for me. In case anyone is wondering why i'm not going with a SR. Drifting puts quite a load on the engine, i'm redlining and bouncing off the rev limiter quite often, a sr with 20 lbs of boost probably will produce the same horsepower as a ls6, but with that much boost and abuse its not very reliable. Plus a V8 has much more torque, something that will benefit a drift car a great deal. Oh, yes, and I can legally drive home from the track.
3) exhaust/header/tranny/shifter fitment. i'm guessing there will be issues fitting basic bolt on exhaust and headers so that probably requires modification and trips to muffler shops. Also i fear that the t56 won't line up too well with the opening in the 240's console, resulting in an altered shifter placement.
I’m trying to get these concerns answered and figured out before I make any plans. I’m going into the Army and boot camp in June so this probably will have to wait till at least November. I have till then to figure things out and see if it is really feasible.
although they are very very similar (same chasis and engine) i'm sure there are enough differences to skew over this type of hybrid swap.
More info can be found at www.kaazusa.com Be ready though, prices range from like $900 to $1200 range for them!
HTH!

TSP 231/237 .598/.595
PRS dual springs good to .660
YT 1.7s
Normally shift at about 6700-6800...
would someone post pics of the front subframe after the LS1 swap?
any comments on steering rack mods if any mods are required?
thanks!!!!!
-AC can't be retained?
-what about power steering?
i live in texas and if i can't keep my beloved AC i'm afraid the LS1 project won't work out.

we just picked up an extra ls1 swap w/a/c, if the compressor will fit in the engine bay you can probably use your s13 condensor just find some a/c lines that will fit and make the plumbing all work together.
