SR20 not good for drag?

[n2o4ever]

Ive heard that the KA is better suited for drag racing rather than the SR20 because of the powerband, can anyone clarify this?

[rpsthirteen]

take a look at the FAQ section that is stickied at the top of the forum.....everything you need to know is there

OMG look what the noob did!!!! you sir *or madam* will be a valued member here I can wager on that!

LOL...yeah, that's pretty impressive there...only 5 posts, and he sent him to the FAQ...it's nice to see he did some research and reading. Good Job.

i have a frend that blew 2 sr20 engines just regular driveing in his g20 in my opinion its a poor nissan engine sr20det on the other hand its tough from what ive herd

s for the answer to your question, the ka24de-t makes power at lower rpmz so the power band is better for drag racing. th sr20det makes its power at higher rpmz so it may prove harder to drag race, also the fastest ka motor is in the 10sec range hte fastest sr20det powered car only does 11's..

It's not so much the powerband, it's everything that makes more sense. I mean that in drag racing, you're gonna blow something up eventually, and parts from a KA are about half as expensive as parts from an SR. That's the honest, simple answer. Another simple answer is that if you use the same turbo on both motors, the KA will make more power, specifically torque, because of the extra .4 liters of displacement it has. It just makes sense if you're gonna drag race only.

I could be wrong, but I think that there was an sr20de, and it came in the infiniti g20 I thought.

Like the old saying goes, there no replacement for displacement. More displacement results in more torque. Since HP = Torque x rpm/5252, there is a direct relationship between the 2. I'll take the motor with more torque, and more on the low end at that, myself. I'd rarther take extra torque at the low end than a little more power on the high end if I had the choice. The torque will find itself more useful, at least with me anyway.

oh, i had no idea that the sr20 came in different cars than the skyline, i guess i need to research a little more...thanks for correcting me

[Chuki_breath]

The sr20det came in the 180sx (that one had the FWD sr20det bluebird I beleive)and the s13, s14, and s15 Silivias (the more commen rwd sr20det). The Skyline (r32, r33, and r34) came with the RB25 and RB26 motors (rb26dett, etc), not an sr20det.

[stealthj]

LOL he thought skyline came with sr20dets!!! LOL

[lorddarkice]

...180sx came with a CA18DET ...didn't it? the sentra (w/e its called in japan... i think pulsar?) had a FWD SR20DET in its SE-R model. the 180 had a CA18, and all of the other S## had a SR20DET or DE. ...or thats what i thought?! i could be wrong someone plz correct me here. (i read the damn faq and then some)

they're not "ten second cars" but the SR doesn't seem to do poorly. At any rate, if you really want a drag engine, do an RB25DET swap.
