[NISSANSPDR]

The 300ZX TT engine is not a good swap...have you seen the engine bay of a Z32?? The thing is STUFFED in there...now...I am not positive...but I am pretty sure that a Z32 is wider than both the S13 and S14...so for you to put that V6 TT would be a tight fit. I am sure it could be done...but no one that I have heard of has done it...I mean the Z32 NA guys always talk about wanting to get a TT engine in their car. It has not been done and most people who want TT and have an NA end up being told to sell their NA and get a TT. So what am I trying to say? It's not the brightest idea...it can work...but would require so much work and custom work. Too costly...and you'd lose the nice weight distribution that 240SX's have...

Possible alternatives...

SR20DET [three versions 205HP(S13) , 220HP(S14), 250HP(S15)]
CA18DET [motor that came in the 180SX]
RB20DET [200HP 2.0 Liter Inline 6...comes from a Skyline...pre R32 era]
RB25DET [250HP 2.5 Liter Inline 6...comes from the RWD Skylines R32-R33]
RB26DETT---->dont know anyone who has done it...but it could work...you need to use the RB25DET tranny though

Other alternatives if you dont care about keeping it Nissan

Small block V8
2JZ-GTE (Supra TT engine...being currently done to a S14 for drag racing)

Pretty much anything is possible w/money...
