Sentra SE-R Shift points.

[RED_DET]

You can't really cry to much about 2.0 60ft on street tires in a fwd turbo car. I'm in the same boat you are in, 2-3hrs to get to a 1/4 mile strip. I have been once to the 1/4 and the 1/8 mile is only like 20 mins away, which I have been to repeatedly. The 1/8 mile gets old shutting down in the 3rd though. Good luck with your tuning.

Were some posts deleted here? It looks like Trav edited his first post, so maybe he deleted others...

Anyway, I can actually vouch for Trav's experience with the QR, built and untouched. The fastest QR-powered Sentras around (and some SR ones, for that matter) pretty much all came from him. Some of them have heavily modded blocks to hold up, others have no internal mods at all and do fine.

The QRs only true weak point is that Nissan didn't thoroughly work out the bugs before putting it on the market. Just as plenty of idiots (a-la the shop my car was at) run SRs balls-out and boosted with ridiculous a/f ratios (in my case, mid 13s on the high throttle map), people screw up tuning on QRs as well, and that leads to problems. At worst, the QR has a finer line between kick*** and damage than the SR. These arguments get as old as the KA/SR/RB/monkeypants ones in the 240 area.

Oh, and clinging to the QR just because it's "original" is just as lame as sticking to the SR because it has a big following. The QR is more "original" because it hasn't been around since 1991.

Personally, I like the SR as a building point better than the QR, but that's more for availability of parts and knowledge and the fact that I have one in my car to start with than anything else.

yay, someone civil who doesn't worship the sr for the fanboism sake.

it's true, parts for the qr are largely unavailable, aftermarket parts are incompatible and nobody wants to even touch it. i've been beating my head against the stock crank angle/cam angle sensor on the QR, trying to get it working with haltech e6x only to find out it's a 36-4 wheel with 2 teeth missing at TDC and BDC, so naturally none of the haltech options fit it. nobody has any parts for the specv chasis.

[RED_DET]

You have 4 posts on this board and everyone of them have some type of sarcastic remark in them. I like the SR, you like the QR, get over yourself and thinking everybody is a SR fanboi. Considering when I purchased my car 13 years ago it came with a damn SR.

[Trav4011]

No one really knows what the QR's limit is.. Because, as far as I know, nobody has found it yet. We've made 323whp/305ft lbs of TQ with our basic, run of the mill, bolt on turbo system. It's 3500.00, all day long.. That engine has been in service for almost 8 months, with no problems. It's bone stock.. and has never been cracked open. The 9.5:1 SR20DE's "safe" limit, on pump gas, is around 350whp. And actually, the rods aren't THAT much larger than QR rods. Yes, there are people that push the envelope, but, they usually break rods or pistons after a while. I've been there, and done that.. back 5 years ago..

Trust me, I love the SR.. and I know more about the SR than I do the QR. But, to say that the QR is garbage, is just flat out ignorant. I'm sorry if that offends you..

I stated in my post above why the QR was a better engine.. I won't recap.. Here's a few dyno charts from turbocharged QR's that I've built..

17psi of boost on 93 octane

17.5psi of boost on 93 octane

19psi, destroked on 93 octane

Stock engine @ 11psi of boost on pump gas

Oh, and to show my love for the SR... here's my race car from a few years ago..30psi and a 80 shot direct port nitrous setup

Travis I don't doubt your ability to build one hell of a QR. It's obviously been proven. I probably went overboard with calling the QR garbage, but I mostly speak of the one parked in my driveway. I guess I got a bad apple, but it only takes one to leave a bad taste in your mouth. Just started an oil consumption test with Nissan. Right now it doesn't seem to be burning oil like it did, imagine that. Could it have been the synthetic oil I have been using? Hell, I don't know. I figured it was the precat, since the 02-03 were having the precat failures.

Both motors built are superb, I choose the SR. There is so much more aftermarket support. Plus what else do I plan on putting into a classic SE-R.

It's time to move on to the VQ anyways. Some RWD action.

[AZhitman]

This thread ROCKS!

Not being a FWD guy, I've learned a ton just reading the "squabbles"!

Hmmm, now to drag this 95 G20t (5-speed) into the garage and work some magic!

(It's got an '01 JDM lowport SR... but only because it was an easy swap.)

[RED_DET]

Glad you enjoyed the lesson.

[nametakennow]

Good to hear, Greg.

That 10:1 motor would love some tinkering. Any thoughts on what you might do?

[roccog70]

well then sell it if you don't like it. Did you get the first years that it came out because everyone I know with 04+ is running just fine .

[RED_DET]

Unfortunately I don't think he got lucky and got a 10:1 motor. Should be a 9:5:1, the 10:1 are very rare and the only way to tell is to look at the pistons. There wouldn't be much difference between the two anyways, both would be nice to have alittle boost on. Maybe he could put a QR in there?

[RED_DET]

If the oil consumption problem continues and Nissan does nothing to fix it, yes it will be sold. Yes, its an 02, never buy the first year car.

[spec_v_girl]

If I had the money I'd take it off your hands... and give it the love it needs. I can't wait to win the lottery... I'm going to go around buying all the unloved Specs in the world.

[robbie2883]

u know the oil consumption has been a well known problem with almost all specs...all anyone had to do was change the header to prevent this. if you are still in warranty then you shouldn't have a problem getting nissan to cover it....but if they do the first thing i would suggest doing with the new motor would be to swap out to an aftermarket header

[RED_DET]

That is a simple fix, but why should one (customer) have to mod a brand new car so it doesn't burn oil? Unless Nissan wants to put a header on for me, then the oem design should work and Nissan needs to fix the problem. Yes it is still under warranty for another 7k miles or 8 months.

My wife does love the car, but after the warranty is done, I'm the one left to fix any and all problems. I keep telling her I'm going to sell it and that doesn't go over to well.

Robbie, did your car burn oil before your build?

[robbie2883]

nope.....never burnt oil...but then again i swapped the header after 1k miles.....and built a new engine after 18k miles (25k on car now)

(here's where i talk about the strength of the QR) i beat the piss out of my stock block for 18k miles....almost full bolt ons and spraying an 80 shot of nitrous....over 300 wtq and went through about 45-50 bottles of nitrous...never had a problem with the engine.....there's not a vehicle on the market that isn't flawed in some area....but a little preventative maintenance and you're good to go. i agree that the dealer should pay for it...but lets be real here...we all know that isn't gonna happen....so at what point do you stop saying "my pen15 is bigger" and just man up and do it? (no offense meant)

[AZhitman]

Good info - Hell, I'd be buying a header with a quickness!

[RED_DET]

I think you SpecV/SE-R folks should read this.

I think you SpecV/SE-R folks should read this.

zerothread/178434

Meh. I'm just hoping I can perhaps get a cheap 2006 Spec out of this whole deal... so it can sit with my '02 and they can keep each other company while I'm at school.

[still4punk]

Lol, all that was wrong with lowport 200sx's was the cams which you can buy now highport cams for less than $50.

The tried and true always prevail. I own a spec and the motor is garbage. Burns oil like its going out of style and it's female driven. Engine has 43k miles and the transmission was replaced with 10k on it, I guess the motor might be next. By far the worse nissan I have owned and all the other nissans I had were powered by SR's, except the G35. Like I have said time and time again, we nissan quit making the classic se-r, they should have stopped there, because its been on a downward spiral since. 200sx was decent, but the lowport design wasn't well liked. Then the b15 se with its roller rocker motor and now lets completely redesign the drivetrain with the QR, that will blowup with more than 7-8lbs of boost on a t3/t4 setup. Unless the motor is completely rebuilt. Hell it will blowup without boost, oil consumption will be the demise.

[RED_DET]

That is true.

[SpecVrooom]

What was in the spec V in the first dyno chart?
