SR20DE in 240 ?

Post by **Nismo31** » Tue Oct 21, 2003 5:28 pm

Does an SR20DE RWD fit in a 90 240sx? if so, how complicated is it? thnks

Post by **Onizuka** » Tue Oct 21, 2003 5:28 pm

if you get one from japan, the swap is easier than the SR20DET because there are less parts like ones associated with the turbo motor.

yea, it was one from japan..wut r ur ideas on it, cuz i can get a great price on one..better than the ka24e ?

It would probly be fairly expensive if you have a shop get it for you, because they aren't really coming over here in large quantities like the det is. It would definitely take a while. On the other hand, if you look around enough, I am sure there is a dumbA** shop that imported the wrong motor and wants to get rid of it. I wouldn't mind having an NA SR in my extra 240. Lemme know what you find out.

i can get the motor n transmission for 800 bucks! its got around 45k miles on it...looks in good shape...he sounds it works n will include a 6 month warranty, but idk how much it will cost to install..is it more expensive than a stock engine?

Post by **ride4lame** » Tue Oct 21, 2003 5:28 pm

It would need to have the wiring changed. It would be a little hard but nothing more then the average mechanic could handle i would imagine. So maybe just a little mre then a stock--> stock motor swap.

KA24DE > SR20DE in the stock power department.

That's all I will say.

More than likely, it's not worth your trouble.

Check here often for SR20DE's.

sr20De > KA24De its the truth go read abouts it. Also the power upgrades are in abundance than the KA24DE ones

Post by **Onizuka** » Tue Oct 21, 2003 5:28 pm

i dunno, i would take a KA24DE over a SR20DE anyday.

Post by **SpeedRacer1** » Tue Oct 21, 2003 5:28 pm

Well if you could get a 200hp Autech tuned SR20DE, would you still take that KA24DE?

Post by **Onizuka** » Tue Oct 21, 2003 5:28 pm

i bet i could get a stock KA24DE + 5 speed transmission for 1/15th the price of a autech SR20DE

exar-kun got like 160hp+tq to the wheels with just boltons for the KA.

Prove it.

As much as I dislike the KA, I think I would rather have a KA than an SR20DE.

But you people also forget that there were three different SR20DE's for the Silvia. The S15 SR20DE makes about 165hp stock.

there is still no price benifit to getting a RWD SR20DE, you would have a KA pumping out much more power for the same $ amount.

Post by **xxtrizz** » Tue Oct 21, 2003 5:28 pm

Yeah ok well look at it like this if the KA24DE is better than the SR20DE then why get the SR20DET? WHen you could jsut put a Turbo on the KA? IF the engine in a N/A format produces more HP (which it doesnt) then why would you go get a Turbo sr when the KA turbo would outpreform it. Everything is Percentages in this process and the difference in horsepower is gonna carry over for similar turbo setups so by saying that the KA N/A has more power inevitably your saying that the KA turbo has more power.

Why is everyone shipping over SR's then? Interesting.

Post by **ride4lame** » Tue Oct 21, 2003 5:28 pm

Uh, yeah, the KA-T is quite impressive. There are pros and cons to both...an sr slides right in. A KA-T is more work...I think it would be cool to have an NA SR though. Don't get me wrong, i love my sr20det. But for my 2nd 240 it might be cool...

Post by **BuudWeizErr** » Tue Oct 21, 2003 5:28 pm

Get out of our forum with your KA-T propaghanda. We would already be in there if we liked KA-T's. Obviously we don't, so get out.

Swapping motors for a 5-10HP increase is for Hondas. That is why I would keep the KA24DE.

Post by **ShadowKnight006** » Tue Oct 21, 2003 5:28 pm

I think it was SportCompactCar did a build up of an sr20de in a 91 ser and blew it up. But the highes hp i found on their dyno sheets was like 154 w/exhaust, 11.3:1 comp ratio using 1mm overbore allowing for z32 pistons,new crank, octane boosterer, ecu reprog, cams, dump pipe, and cam gears. If this is right, as much as i like the idea of being different, I will stick with my KA24E.

Post by **matt147** » Tue Oct 21, 2003 5:28 pm

Kojima is making 184 wheel hp in his na 200sx se-r with all the available bolt ons and a built motor. Cadle made 165 wheel hp in his 91 se-r with all of the bolt ons and C3s but stock bottom end. These are both just de's not ve's.

Post by **Onizuka** » Tue Oct 21, 2003 5:28 pm

FWD motors do not suffer as much drivetrane losses as RWD motors. Not only that the transmissions that comes with RWD SR20DE's have shorter gearing to make up for lack of power, and are designed with japanese speed limits in mind, unless you prefer driving at 4,000 rpm at 70 mph.

As far as KA-T vs SR20DET, show me a KA-T thats making over 500hp on the stock bottom end, because i have several exaples of SR20DETs making more than that on the stock bottom end that i can link in about 5 seconds if you want.

Post by **matt147** » Tue Oct 21, 2003 5:28 pm

Yes a fwd layout has less parasitic loss then a rwd layout. Prob about 5-10% if I had to guess.

As far as the ratios are concerned the best thing to do might be to switch the bell housings and use the usdm gears I guess.

Are the det ratios short as well?

Post by **Onizuka** » Tue Oct 21, 2003 5:28 pm

DET gears are the same as the KA's.

Now a cool swap would be the RWD sr20de block, turbo transmission with FWD sr20ve head and ECU and GTiR indevidual throttle bodies. 190-200 N/A horsepower as a base!

Post by **matt147** » Tue Oct 21, 2003 5:28 pm

Yeah that would kick ***. Add the SR16VE cams for an extra 10hp too

Are the S15 DE's roller motors? Its been said that the VE heads can be bolted on the fwd roller de's with minimal work.

Post by **Onizuka** » Tue Oct 21, 2003 5:28 pm

im not familiar with the term roller motor

good idea with the SR16VE cams though!

Post by **GraySilvia** » Tue Oct 21, 2003 5:28 pm

I think he's referring to the 2001+ (i think) USDM SR20DE's cause they came with roller rockers and a few other improvements...

As far as the SRDE vs. KA battle....i think for a SPORTS CAR the SRDE would be more fun because it has the more 'sporting' power band. I.e., the KA is dead above 5500, whereas the SR is starting to make its power. Now, granted you'll be way down on torque with the SR, but if i could find one cheap enough, i'd probably give it a shot if i had a stock 240 and was just bored as far as project cars go.

Post by **Onizuka** » Tue Oct 21, 2003 5:28 pm

I inquired at a SR20 parts store about building a project like this, supposedly the sr20ve and sr16ve parts are very expensive.

me want 200hp NA SR!
