Which fuel injectors

[92tsifwd]

Are 450cc injectors big enouph for the folowing mods?
I have a 92 Eagle Talon tsi fwd w/ folling mods

90 jdm galant vr4 motor w/ ported intake man, ported 6cm small 16g, ported exhaust man, o2, turbine house, 3 inch press bent catback with high flow muff, 2g mass w/ dejon tool 3 inch intake pipe, full dejon tool 2 1/4 uicp, rx7 turbo fuel pump rewired, boost restrictor removed. With no more added boost can i run on stock injectors? If not what would be a good size? Will I need anything else?

You're pushing the limits of the stock injectors, if you're running any more than stock boost, you're pushing your luck

I would go with something larger, like 550s or 660s (for added safety) with that setup.

You'll need something to fool the ECU into not running super-rich with the larger injectors. The tried-and-true way is with the SAFC, which is also reasonably cheap. There's also the new-ish GM-MAF Translator (which also elminates the stock MAF), but that has less tuning ability than the SAFC (You could also get both). Then there's the option of getting a different ECU ROM (If you have a socketed ECU) from dsmchips or wherever. You could also "grow your own" ECU ROM if you're the DIY type.

Also, this is about as far from 'Extreme' as it gets. Make sure to post in the right place next time, mmkay?

Ok, Thanks for the advise. I will plan on getting 550cc injectors and a safc later but until it is in my budget i will keep an eye on my boost.

RC 550s would be great for your application.
then like everyone else said.
