QR25DE vs SR20DET

[nlzmo400r]

well i like both engines, but which car would be faster, i dont really wanna know personal preference, or why u would build another, i know the sr20 has much more potential (and probably with everything else), but an o2 SE-R (stock) against a 93 240 w/sr20det (stock sr tho)on a road course, who would u pick to win and why

[lessthanjakejohn]

stock 240 chassis?

Id say the 240 would take it, easy

[nlzmo400r]

really?. hmm. i wouldnt be surprised if hte sr won, but i wouldnt think it to be an easy fight, the new spec Vs handle greatly, and the torque is amazing and hp to back it up isnt bad either, id LOVE to see a vid of this if anyone has one, and the sr has a few ponies on it, but not as much tq as the QR, i wouldnt call this an easy fight, but then again, imite be way off base here as well

I'm thinking that most road courses have a fair amount of straightaway and so therefore the SR will be able to pull ahead there. The SER spec V has a great suspension set up from what i hear, but its FWD and lacks power.

The stock 240 suspension is soft but in top notch condition it should get the job done.

With both drivers being the same?

naturally, its only fair, and nice hearing from u again, havent seen u since the altima forums got any posts

.

I definitely wouldn't say the Spec lacks power but I guess compared to the stock SR20DET model that it does lack a little. The Spec would hold its own if the track was really tight but I agree, the 240 should pull on straights cause it should own on the top end.

I think it would matter which track you were racing at.

As for which is the better engine. I would say the DET just cause it is made for boost and can handle it. It is still questionable whether or not it can hold boost well however we should find out soon cause I know of a project Spec V that should be boosting and is expected to be able to put down 400whp (we'll see).

well the pros for the se-r to me, would be fairly lightweight (about the same as teh 24o), the gearing, the torque for coming out of corners, and as far as straights, id say the se-r could hold its own against a 24o (sr20det), ive heard tho, that sr20det 24o's pullin 14.2 stock, i find that hard to believe, either way, id say itd be close

budweiser with his S13 is pulling a 14.1 with a semi stock SR (front mount) I think he hopes to break into the 13s with beefier tires.

[Cold_Zero]

Im lost, are you road racing the two or drag racing? The conversation keeps switching.

[lessthanjakejohn]

Road Racing, but comparing the speed of the cars which is easier to do by comparing drags rather than comparing HP (most of the time)

[Cold_Zero]

ok, but a drag race (typically quarter mile) is normally performed from a stand still to top speed. In a road race you normally hit a straight away coming out of a turn. There are so many different mechanics that go into a race.

I'd say on a very tight course, like an autoX course, the Spec V would have the advantage. However, on a roadcourse, the SR 240sx would.

The spec V's suspension blows away a stock 240's suspsension. And it has much nicer gear ratios for an autoX course than the 240sx.

But on a roadcourse, the 240's power would overtake the spec V's handling. A good spec V driver can take a medeoker SR 240sx on a roadcourse, but if the drivers are equal, the 240 would win.

Also, the 240 is less likely to blow up.

thats what im sayin, i don think the power difference would be that much, especially comin out of a turn

I'd say you don't even need a long straight in a 240 to pull away. If it was just a roadcourse at all, the 240 would probably win.

[nlzmo400r]

hmm, damn, this is about what i figured, but i just like the spec v so damn much, why cant they keep up with a car thats damn near the same (such as a type S) 2oohp and only 142tq!!!, yet its still more than 1/2 a second slower in the 1/4!!< damn this isnt fair, still i love hte SR2o, and they would probably win on a road course, i just didnt think itd be by that much ya know

[lessthanjakejohn]

because the QR has frickin truck engine charateristics

[nlzmo400r]

yea but still, it should be quicker than a car with 4o less ft lbs of torque, and only 2o more hp, and the weight is the same, and both come with 6speeds (spec v is a lil closer ratio)

[EZcheese15]

Um....ok...the SR is about 40 more HP, and 20 more lb-ft. Not to mention, it's the area under the curve that really matters anyway. And since the SR has a much higher rev range, more HP, *and* more torque....then it will be faster.

[nlzmo400r]

o, sorry, i was talking about the RSX-type S, not the SR in that post, i brought up the fact that the TYPE S is considrably faster than the spec v, yet has so much less torque

4 tenths off, but yea, with a limited slip and some better tires, i think 13's are possible. But I don't think I'll ever see it...

Damn, I can't read... I swear that used to 14.1.

[nlzmo400r]

damn man, how many pics u gonna have on ur sig??< looks nice tho, and BUDWEIZER, do u have any plans(plans, not dreams!haha) on modding ur sr20
