STILLEN QR-PRO ecu upgrade

[TeggyLS]

Im looking at buying a spec-v. Im just looking at some of the upgrades first. any one had any experience with the STILLEN QR-PRO. How much power would i be looking at, or is it just a waste of money for the 400 bucks? Any other ecu upgrades worth looking at?

[sr20de4evr]

I wouldn't trust stillen with anything, especially engine management

there are no other ecu upgrades out there, focus on the bolt-ons first anyway. I/H/E, pulleys, flywheel, cams, then after that you can look into other stuff like an ECU or piggyback system.

Ya i already scoped out the other parts i want, was just lookin at the ecu for the final addition. From what ive heard, flywheel/clutch and a short throw shifter/good trany fluid should gain me the best results for startes. Im not lookin at turbo, i have a turbo on my integra, and i just want something with almost stock reliability. This is what i was lookin at doing to a spec v, if i do go that road.



hotshot header
greddy evo exhaust
Injen cold air intake
JWT camshafts
balance removal kit
unorthedox pulleys
b&m short shifter
JWT flywheel
act clutch
transmition fluid


anti roll kit
tein ss coilovers
motor mounts
strut tower bar
17 inch rims/tires

brake pads
brake lines
brake fluid

sounds like you've got it all planned out, with some quality equipment no less (that's not exactly the norm with the newbies around here )

Only thing I might change is the b&m, they make a very high quality shifter for other cars, I have their ss on my SE (different shifter than the se-r) and I love it, but they screwed up on the qr shifter. I'm not sure if they've fixed it yet, but there are other choices out there that you won't have to worry about. The mossy shifter was a quality one, but I believe it's been rebadged under a different name....nismo maybe? I haven't checked into it. Either way, do a little research and see if the b&m problems are gone, www.b15sentra.com is a good resource and I'm sure there's something on there about it.

The rest of those mods should hold you over for a while though, JWT has been working on an ECU but it's a tough nut to crack. I think they're pretty close, if they haven't cracked it already. Hopefully by the time you got everything else running it would be released.

Also, the spec comes stock with a strut tower bar, an aftermarket one really won't give you any improvement at all. If you want it for cosmetics then by all means go right ahead, I just thought I'd let you know that it won't give you any handling improvements over the stock one.

ah ok, thanks for the information. Ill look into that b&m shifter. I saw the strut tower bar and id like something a little nicer, i might just polish it up and call it even. I like to research stuff alot before i purchase a new car, no point in buying something if you'r not gonna be happy with it.

Any suggestions on rims? Im thinking one something a little bit wider, with a r compound tire.

yea i just bought a 04 spec v with the brembo brakes and i was wondering about the stillen ecu myself... however i did some research and the best header out there for the spec v is the nismo r type header without the cat.. it gives 16whp, the catted version makes 12whp... what is the best cat back available? i know the nismo s type only gives 4whp and i wanna find something stronger to go with the r type header... also the nismo gen 2 cold air intake gives the best gains i have found so far.. 8.7whp and 11 for torque... dyno's have shown that the aem only gives a couple of horsepower at the wheels so its a waste... thjeres also a lot of ghetto mods that can give power.. like relocating the knock sencor, or removing the brackets in the oil pan.. i figure with the following setup i should be in the low 14's which is plenty fast for a daily driver..

Nismo header 16whp
nismo catback 4whp
nismo cold air intake 8 whp
nismo cams unsure
underdrive pulley

what are ppl running in stock trim? i know a couple of magazines have tested the o4 and have gotten 151 stock whp and 1/4 times of 15.2.. just wondering what ppl are running at the track?

A flywheel/clutch setup with a short throw shifter will drop your quarter miles signifigantly.

you put too much emphasis on the numbers from a single dyno, I guarantee you I could do 3 dynos of my car back to back and have a difference of 5+ horsepower between them. Who's to say that some onedid a stock run and got a low number, then did a run with a cai (whatever brand it may be) and got a high number? And maybe someone else did it with a different brand and it was reversed. The power gain from any quality header (nismo, hotshot, aebs) is going to be close enough where it doesn't matter, the same goes for exhaust and intakes. Also, there's no way in hell you could score low 14's from i/h/e, cams and pulleys....not even close. Most people with i/h/e can't even break into the 14's at all, and if they do it's in the 14.9's.

Anyway, about rims, that depends way too much on your tastes. No one else can tell you what will look good, only you. The stock rims are wide enough for any tire you can fit on the car though, there's no reason to go for a wider rim.

[TeggyLS]

Yep, You will get the most gain out of clutch/flywheel, short throw shifter, Some light rims and sticky tires. Practice your shifting and take offs, theres always time to gain there.

I think ill just stick with the stock rims, i kinda like the stock sleeper look better, then flashy rims or what not.

I was lookin on JWTs site and saw they have a clutch, is it just a rebadged act or something? IS it any good?

[sr20de4evr]

I haven't heard anything, I imagine it's good, but it's pricey. I haven't looked at the QR one specifically, but their clutch/flywheel combo for my car costs $1500.

[TeggyLS]

:S ya, i think ill stick with a act clutch, havent failed me in the past.

[daveshapellSVT]

well maybe ppl suck at driving cause the car runs 15.2 stock, and the header alone gives a good chunk of power so if ppl can't break into the 14's then they are the problem.. two tens of a second is nothing especially when you gain as much as 16whp from a header alone... But i guess i'll find out soon enough.. Also the upgraded clutch won't do as much as you think.. it will just engage harsher, and be stronger. as for the flywheel i'd hold off on that unless you autocross or something cause the rev limiter already comes up quick thanks to close gearing and a low redline.. I don't see how those three things would benfit more than over 20whp with bolt ons..

[TeggyLS]

every car is different, and yes of what i have seen most have problems breaking into the 14s with only minor bolt ons. i think u might get 16 whp from a i/h/e combo, and it all depends on climate and altitude, the same car could run a 15.0 one place but a 15.6 somewhere else.

[daveshapellSVT]

well yea we aren't talking about extreme conditions.. just normal ones.. Anyhow i'm pretty confident that i can pull a 15.2 at my track.. i have a lot of drag racing experience so i know how to drive.. I used to have a 2000 Z24 and most guys were running 16's and i ran a 15.3 with mine.. some ppl just suck at driving.. i garantee i can get two tens faster than most ppl.. I actually thinking of going to the track tonight if i can get out of working tonight so if i go down i'll post my slips..

it doesn't have to be extreme conditions, just normal day to day stuff

When I first went with my car (with a wai and short shifter) I couldn't break a 16.4 for the life of me. I went back, couldn't break a 16.2. I went back, ran 15.8's all day long. I went back 2 weekends later and couldn't break a 16.6.

It takes VERY good weather to hit a 15.2 in a stock spec, I personally know 10+ people with spec-vs, some fully bolted and some stock, and I only know one person who has broken into the 14's, and it was a 14.95. If you keep your hopes up like that you're going to be sadly disappointed, I wouldn't expect any more than a 15.4-6 on your first trip in a stock spec, and depending on the weather it could easily be up in the 16's.
