imo, i think if you get a 240sx, try to find like a 92+ i think thats when they started puttin in the KA24DE, twin cam. i just sold an S14 this past month to buy my current FD. i had big plans for it, but i missed my rx7 too much, so i got another with the same amount of money you spend on doing an SR20 swap and parts/labor n stuff you can have a semi-built KA making almost twice as much power and a **** load more torque. not to mention there is a buncha cool **** for them in japan :bigok: good luck!

 

There isn't as much available for the RB20DET as the SR20DET, that's for sure. I wonder if that has to do with the SR being in Silvias as the top engine, while the RB20 always played second fiddle to the RB26. No denying that more power has been achieved from the SR20 than the RB20.



Quite honestly all I know about them is from research, not experience. In a couple years I'm planning to get an R32 GTS-t, and then we will see.

Like Benny said, you need to go with a 91+ 240SX since they came with the twin cam engines to begin wth. As fasr as building the KA motor, I know a few people with fuly built KA motors and you none of them have been able to go 10's and stay there. Thiose truck motors, although they can be built to go that fast, are not relaible at all in the 10 sec area. If you are going for a high 11 sec or slower car than a KA is not a BAD idea but it takes alot of work to get it there.



The SR20DET is much more reliable for higher horsepower cars. If you build the motor than your biggest concern is the tranny because they are pretty weak above 400hp and **** starts to break.



One of my friends just bought a 92 240SX and is swapping his motor/tranny out for my other friends 96 240SX KA motor/tranny since that friend is going SR20DET in March. His cost for the SR20DET swap is $4500 total with the new motor, tranny, EC, wiring harness, downpipe, midpipe, Apex'i Intake, Greddy FMIC, and the installation of all this. Not bad in my opinion. Then his only other mod is a Apex'i GT spec exhaust.



Then my other friends KA - KA swap is costing him $500 for the labor. The guy doing these swaps can also do an RB26DETT swap from an R33 or an R34 with the sequential transmission as well. The R33 swap is like $11k and the R34 swap is $15k. So if you buy your 240SX for around $2000 and swap the RB26DETT from an R34 and build the motor, tranny, and install a larger turbo uprgrade you would have one mean ******* car for under $30k. Hell a stock RB26DETT in a 2800lb 240SX would already run mid 12's easy. If it can pull a 4000lb car across the 1/4 13.6 then it would haul *** in a 2800lb car. Based on the 100lb per.1 second theory you are looking at a 12.4 second car in the 1/4 with a stock RB26DETT motor. Not bad for $17k.

 

Are those RB swap prices including the sequential tranny? cause that's pretty good value if that's the case

you don't NEED a 91+ mine was an 89 and it worked just fine. Ends up costing about 100 bucks more for the dohc powersteering lines, and you have to switch the tach from the sohc to either the sr20 or KA24de tach. Thats pretty much the only difference mechanically. PM me if you want more info, turbo KA is a pig!

 

DJ Rotor: The RB20DET was in plenty of cars. The RB26DETT is now where even close to being as plentiful as them, but it still got all the attention. The 2.0 RB just isn't the best engine to go with if you want to start a project over here in the states. It'd be unique that's for sure. But it'd also leave the owner wanting a lot more. The RB's did not have sequential tranny's.

 

I know they didn't - that was talking about what lane_change said, about the swaps that this guy was doing.



What you said about the RB20 v. the RB26 was basically the same as what I said.



The RB20 will come in my Skyline (unless I can manage a GT-R), so it'll be the obvious engine to use and actually the best engine for a project in North America is a 350 Chevy



Cheers

The $15k does include the Sequential transmission. Your extra $100 was part of why it is easier to swap into a 91 or newer 240SX.

 

Oops, sorry. I wasn't sure what you were driving at. ::note to self - work on reading comprehension::



A R32 GTS-t in Japan goes for about $3k. This is for a good car. Motorex charges, at a minimum, $18k. That's a lot of cash for a car that is at least 10 years old. They barely do 15's stock but they do feel faster than that when inside of them. The owners of them always think they are fast as **** in spite of stock S13's with the SR20DET being much faster than them.



I knew a guy that dumped all sorts of mad money into one to build it up. In the end he had a car that was just in the 13's or 12's. This was when they were still pretty new and more stuff was available for them. I have always liked the way the GTS-t Type M looked, but for performance they are a disappointment. I almost bought one to replace my '83 Skyline Newman that I balled up on the side of a road. But that was a long time ago.

 

And if I were in the States, I'd have to go through Motorex. But since I'm not . . .



About $3000 for the car, plus about as much again for shipping/duties/taxes etc, I figure is not bad value for a car that does have as much potential as I'd want out of it (it would be more-or-less daily driver most likely, and 13's would be plenty), and would be a very unique head-turner.



Wouldn't work for an only vehicle of course, but that isn't the plan.



However if I can scrape together enough $ for a GT-R, that would all change . . .
