I'm looking to upgrade the stock injectors. does any one know any good brand or where to search for some?

Does a fuel injector upgrade increase the horse power at all?

todd0305 · 01-31-2005, 12:48 AM

Yes it does, but i'm going to upgrade intercooler, fcd, sparkplugs, and sparkwires for more gain

chances are you won't need the injectors.

are you still using the stock turbo? if this is for mk2

JekylandHyde · 01-31-2005, 05:07 AM

If you have the stock turbo (CT26) you will HURT performance by going to a larger injector.

There is no need to upgrade the OEM spark plug wires.
If you want to eliminate fuel cut, you can do that for FREE.
If you want to raise fuel cut, you need the FCD.

Spark plugs, just get the NGK coppers (6097) and change them every 3000 miles. If you are only mildly modified, get the OEM platinumn plugs.

The Intercooler is a great idea.

supra....MKIV twin turbo injectors are the most common ones used....

All stocks really, Apex intake and open exhaust is all that has been done. I heard that getting larger injectors would hurt the car then i gues i won't do that.

JekylandHyde, How to eliminate fuel cut?

what would you guys recommend as a good intercooler?

Plug the hose leading to your boost pressure sensor to eliminate fuel cut.

todd0305 · 01-31-2005, 10:07 PM

will try.

JekylandHyde · 01-31-2005, 10:13 PM

I recommend the GReddy intercooler. Give Aaron at ATS a call and tell him I sent you.
Just click the photo in my siggy to get to ATS's site.

AS for fuel cut, simply cork the vac line to the MAP sensor. It is located next t othe little box that says "DIAGNOSTICS" on the engine/trunk firewall.
This will also STOP your OEM boost gauge from working.

All the MAP snesor does is operate the OEM boost gauge and fuel cut.

WOW thank you very much.

Variance · 02-01-2005, 06:23 AM

Get all your bolt ons finished. Intake/Downpipe/Exhaust. A boost gauge too. If that's done.
Raise/Disable fuel cut. And get an Manaul Boost Controller raise it to 15psi. Get the copper plugs like JH said if you want. And enjoy it.

anything after that will cost $$$ lol. But even after all those mods the car will be a lot more fun to drive!

JekylandHyde · 02-01-2005, 08:57 AM

Great point.

I would not recommend disabling fuel cut unless you have a real boost gauge!

todd0305 · 02-02-2005, 02:58 PM

already have boost controller and boost gauge. have not install boost controller yet.
