[jasmos]

thanks for the information

[jdmlude2000]

wow that is the most complete info that i have ever seen thanks

[nismoron]

That was a lot of good info... I have a correction though, about the KA turbo and RB20 swaps. I have done a few of both of them I have an RB20DET in my 240. I only paid $1200 dollars + $635 shipping for an entire front clip from an R32 with 215hp. My best friend and I just completed a couple of KA24DE turbos and they were much more difficult than the RB's. The RB's just bolted in (with Unstable-Hybrids motor mounts) and all we had to make were downpipes and swap about 7 or 8 wires in the harnesses. The KA-T we had to fabricate ALOT! Downpipe, oil lines, heat sheilds, and ALL of the intercooler piping. The R32 piping from my clip just bolted right in on the RB swap. You are right about beating an SR though... I have raced 3 and crushed them all. The only one I have times for was my 13.73@104 vs the SR at 14.90 (dunno trap speed), and I was spinning a little in first and through most of second. The RB has NO power below about 4000rpm though, but it keep pulling harder and harder until the rev cut hits! There's more power up there with some valve springs and retainers (and remove the rev limiter)
Also the VG30DE (from a Z32 )swap is pretty easy as well just use a Z31 tranny and fab some motor mounts and a drive shaft. 225ish hp and a WIDE torque band for drifting! We are working on one now.

i downloaded the 240sx FSM and it doesnt seem to have the 89-91 model servicing information ,

[LAsBestcom]

Looks Like you Guys have all Over Paid...Formula D website give you links to the drivers / teams websites and all the guys have great contacts for everything you need for an import tuner. If you call any MFG. and give them a good story about building a Formula D car LOL some companies will send you free parts...Sparco, KAAZ, Exedy, KW Suspension, Griffin Radiators, Auto Meter, Turbonetics <---Top Give-A-Way Companies.

[bam 240sx]

looks like youve done ur homework. only thing is that CA18's avg now around 1k, just not a lot of aftermarket support and a pain in the ass when you start making real power. rb20's are nice but the thought of a 2 liter inline 6 always seemed a little small to me. rb25 is how alot of guys go to get good power, only thins sucks ass is parts and let alone the availability of them. my buddy's friend broke his rb25 tranny and its costs around 1500 to replace, if you can find one. so the kid had to give my buddy his SR20 redtop(s13) in return for breaking it.

either way you need $ to do it. and KA-T does have reliability issues, but can be avoided if you constantly look after it. and the KA-T is a torque monster compared to the sr and has an iron block.

just some info i figured id share too, but AWESOME write up. + 1 for you haha

some ppl need banning for bumping 4 year old threads....
