Potential Buy 1997 GSX

[asshanson]

Huge injectors on pump gas will hesitate on partial throttle cruising. No way around it unless you get smaller injectors. Congrats on the purchase.

What injectors does it have?

[SlowWhite]

2200cc.

if i were to downgrade injectors what would be a good 93 oct injector.

My guess is 2yrs till i go with turbo upgrade unless a black turbo or something comes up for sale that bolts up to the fp manifold and punishment 02.

[SlowWhite]

also anyone understand how the boost control via link works? everything on this car as far as management goes is taken straight off ecmlinks website/parts list.

before ever looking at how it works i was thinking it would just be as simple putting in the boost you wanted for each rpm range, but thats not the case lol and the numbers aren't making sense to me as to how its calculated.

cars only running 17psi right now and was tuned for 22psi would like to get it back to 22psi.

Just type in your power goals and it'll spit out an estimate of what you'd need. Sometimes it's nice to oversize your setup to support more power in the future, but with injectors you have to remember that generally with larger injectors comes increased risk of idle/low throttle issues. So if in 5 years you think you'll be at 700hp, but for now you're at 400, I'd probably get injectors more suited for the 400hp you're at now rather than hugely oversized ones for possibly 5 years down the road.


If you don't need huge ones, the FIC high-z 900-1000 injectors worked extremely well for me on my SC300. Otherwise I'd just talk to your tuner because in the end he's the one that's going to have to deal with tuning around your injector choice.

what tuner lol, I now live in a small towns whose primary business is farming pine trees for paper mills.

but ya I was thinking the same thing. I was going to possibly upgrade turbos this tax season but I want the car to look up to par first. And figure paint, and interior would probably already take up my half of the taxes next year.

thanks for the link, i had rc 550's in my old car and never had any problems.

[Halon]

I suppose you could just keep those 2200's around in case you need some huge ones for the future if you ever plan on making 600+ or something. And in the mean time with an HX35, you could grab some affordable 650 - 750 sized injectors that should be plenty when talking pump gas power levels, and will likely make daily driving much more comfortable than the 2200's.

Yes it's very easy. Go to the Boost (WGS) tab and look at the Base Duty Cycle chart, highlight the range you want to increase the boost and hit ctrl + up or simply raise the numbers a couple points. Then test drive and see what boost you hit and tweak it until it's where you want it.

If your logging a map sensor and you have a good base duty cycle chart setup already then you can enable the error correction feature which is pretty cool. But I just use the base duty cycle chart.

I was thinking the same. So long as nothing comes up my next day off ill be heading to north carolina to pick up basically full interior for the car and then ill be painting interior based on the write up on tuners.

Since they didnt make a full black interior and I have to paint parts anyways I am leaning towards just buying all grey as its half the price as black pieces. then painting all of it that way its not two tone blacks.

Ill be having the roof liner and sunroof slider done in black as well just have to get the local guy to go me a date he can do and fix the liner in the 740
