Q power?

[Nismo_Freak]

You'd also gain, what, 3-12 whp with a manual with lightweight driveshaft from driveline loss

Say you gain 5-8% with the manual swap.

Given 278bhp, you'll see a gain of 13-20bhp in just the 5-speed conversion alone. Factor in the lightweight flywheel and you'll not only gain power but response.

How do you guys feel about a tuned ECU for the Q45?

[DenverQ]

Ill take one of everyhting!!!!!!

PS Hey hitman!

[rahiel aziz]

are u serious or just teasing us.lets start with cai and see where goes from there .if u are serious than count me in with few dollars to spare.this will be another best thing in favor of Q i mean first this board thanks SD than dennis and next u will be. NOTE:i just changed fuel pump in my 91q two thumbs up for the member who posted those instructions with pics.took three hous

[AZhitman]

'Sup Tory!! Long time no see!!!

I'd jump on the ECU right away.

Let's table the manual discussion, as I don't think ANY of you are considering the following:

1) Where to put the clutch master cyl2) Where to put the clutch pedal and linkage3) Where to put the E-brake (console?) 4) Cutting and trimming to resahape the transmission tunnel5) Cutting into your console for the shifter (it won't fall where the auto shifter is, trust me)6) Minimal gains for a HUGE investment

I'd bet after all this you'd be LUCKY to get away for $5K for a MT conversion, which is more than what some of these cars are worth.

Concerning the CAI design. A lot of the restriction is found in the actual stock piping itself being designed to deaden the induction system's sound. In order to effectively do that they have to create bends and bottle-necks in the piping, which are restrictive on the top end.

Actually, restrictions usually intensify induction noise. Same with the "bends and bottle necks." Bends are not necessarily bad, and the bottlenecks are pretty much non-existent. The chambers are for tuning to a harmonic at certain rpm and protection from water ingestion.

One would have to invest some time in a flow bench testing and prototype fitting to get something really better and for how much power, while keeping the torque curve flat? A serious investment by an engineer knowledgable about air flow for what possible return in the market?

And no way I would step down to a K&N. Cheap is not an option protecting this engine.

I am fully aware of how intake systems are designed and how they work, don't doubt that just because I didn't post every formula to prove you can improve flow by X% that I don't know what I'm doing. Anything I make will be fully backed up by numbers on a dyno, and CORRECT numbers at that.

How do you guys feel about a tuned ECU for the Q45?

My requirements:

1. Price under $300 with swap2. 3 way selector switch "Economy - NORMAL - Power"3. Flat $50 fee for future tuning upgrades.4. Make one for the '94 model

These may be outrageously low to you, but I can't help what I feel.

Here are my opinions on other mods:

CAI:I have the K & N kit, and let the filter dry for about 3 months, before installing it (I have 2 filters). I clean it every 3 months, whether it needs it, or not. I do NOT over oil it. I clean my MAF, and all associated tubing every 3 months. I could be hurting my engine, but I don't think so.

Definitel would like a polished aluminum pipe to replace the stock plastic pieces. Don't want to suck water from the wheelwell. It rains all the time in Alabama.

Exhaust:I HATE the look of the stock rear resonator. I would like to see a replacement muffler-back kit, that had dual resonators in the rear. Possibly an adjustable backpressure valve, like in my stock 2000 I30t muffler. 3" dual tips is a must.

Engine Dress up:Whatever you got. I show my engine every chance I get. It is impressive. A little "bling-bling" under the hood would be nice.

Forced Induction:Sounds good, but probably not an option, for my car, until I get another daily driver, and some cash.

6 Speed transmission:I'll get that when I get the Supercharger kit.

Nitrous:Definitely interested. Under $1,000.00 for a 2 hour bolt-in kit with the WOT and on/off switches.

12.5 Brembo Brake upgrade:Tell me where to send the check!

I concur with Jeff on most of this, but I'll take one that's NON-switchable, still under $300 (should really be less than half that if I provide the ECU), and covers the 94-95 non-active non-TCS models.

I have an extra ECU coming... MUAHAHAHAHA!!!!

If you don't do it, I know aaacomp will.

[SOCAL91Q45a]

AZ .... prior owner of my car advises me that the JWT ECU and car was taken back to stillen with the complaints of "pinging" - on the original factory motor. Supposedly Stillen shipped the brain back to JWT for a mod/de - tune and corrected the "pinging". My buddy - the prior owner is no car novice - but Im not sure it was or was NOT pinging - this was a long time ago circa 1996-97.

So .. im wondering if I will be rollin a de tuned JWT ecu, and if some one can provide guidance on how to check that out without dropping the perverbial "bank" to scope it out?

aaacomp does this kinda stuff? JWT mod their stuff for a decent price or whats their spiel [if ya know]

Thankx,

Steve a.k.a. SoCal

[AZhitman]

If the ECU was indeed modded by JWT via Stillen, there's likely some record on file with JWT. I'd contact them and have them "check" your ECU for proper operation.

They're notoriously hard to get in touch with (some will disagree) as I've NEVER had any luck contacting them. Overpriced reprogramming IMO, considering the ease with which they do so... But I digress.

[elwesso]

Youd also have to make ones for TCS models.......

Id go for the ECU if it really made a difference...... Maybe you could integrate some sort of "bypass switch" for all the systems that retard the timing....... Like a dash switch....... For normal driving, have it work as normal, but when you want to go fast, have it on full power......... No one would have to worry about knocking because I AM POSITIVE that no one uses ANYTHING but 92 or 93 octane......

[bgilly]

An ECU re-program would be great. But I have a '94 Q45 with active and TCS, so I'd want it to work with both of course!

[DAEDALUS]

I AM POSITIVE that no one uses ANYTHING but 92 or 93 octane......

Except, of course, for us poor souls in areas where 91 octane is the best you can find.

[Jeff Williams]

If I could improve performance with the ECU, I should be able to improve the gas mileage just as easily, for the long road trips, where performance is not important. If I could squeze a couple of MPG out of the car on the highway, I wouldn't mind loosing a few, while cruisin'. That is why I would want the 3-way switch.

[AZhitman]

Except, of course, for us poor souls in areas where 91 octane is the best you can find.

LOL - Be glad you can get THAT! Quella's been guzzling 87 octane (Coors Light) for the past week.

91 is the highest we ever see, too.

[90Q45blue]

Coors Light is 87 octane now? I would say 87 octane is like the Natty Light or Fat Cat of gasoline.

Nick

[elwesso]

:jawdrop: NO PREMIUM....... :eek

Thats terrible, I feel sorry for Quella, and all the other Qs that have to live on coors.....



Gas prices are as high as theyve ever been here..... 1.77 for premium..... I got a half tank, you can bet ill be waiting until next week......

[DAEDALUS]

It costs over $2 for regular here. I just filled up yesterday. Premium (91) was $2.16/gal at Costco.

[elwesso]

OOOOH..... Thats killer....... $44 to fill the tank..... Id rather walk!!!

[90Q45blue]

Nismo,

Tell us more about you plans. I'm gettin all excited about these mods!

"OOOOH..... Thats killer....... $44 to fill the tank..... Id rather walk!!!"

PANSIES ... LOL

Try my V10 Excursion on for size at Chevron in CA - $44 .... buwahahahahaha ...

44 Gallon TANK brother !!!

Fortunately the wife and kiddies only roll about 15-16k per year. But at 8.9 MPG - its a ball breaker.

[maxnix]

Thats killer....... $44 to fill the tank..... Id rather walk!!!

Anyone who habitually runs the tank to empty before filling it will sooner rather than later when the fuel pump fails.__________________Brian1995 Q45 & Q45t

Pretty much what I've listed is what is on the roster.

[Stoneage_Turbo]

i bet those kids would make a killing if they could make a replacemnt driveshaft kit for all the Q45 guys that had bent ones

Single peice aluminum driveshafts? :icesangel

[DenverQ]

Ill take a ecu!

[elwesso]

Any updates on any of these things..... Or is this another great idea that we let fall through!!!!

[knghtryde]

Yeah. Has any of this stuff been tested, or does any of this stuff have an estimated time for release. Let us know. We're waiting patiently.

[Jeff Williams]

Priority sounds like it should be:

1. ECU programming (JWT has, aaComp has)2. TCU Programming (JWT has)3. Performance Exhaust (BRM is working on)4. CAI 5. Supercharger6. Stronger transmission (Level 10)7. Manual Trannu conversion
