Well I want to upgrade my secondairy injectors on the AE. I would like to go with the 720 cc/min injectors. I am wondering how much boost can I safley run with them, assuming everything is tuned correctly, and working right?

With the stock IC you shouldn't really go past 10 PSI.

So I should go with a FMIC before upgrading the fuel system?

Doing the fuel system first is a good idea, but the stock IC may not be able to cool enough past 10 PSI. Hot intake air is bad, just like running lean.

Yep! I didn't know what to go spend my $ on first. I'd love to ditch the stock IC. I guess I'll have to keep my eyes out for a big ol NPR IC.

You won't need the injectors for a while.

I just want to make sure the car will be safe when I toss on the RB turbo back exhaust.

ILUVMY88CABRIO 06-23-2002 06:51 PM

So would it be safe to just use a FMIC with the exhaust? Or should I get a Super AFC. I don't want to rebuild my engine untill I'm ready to.

The IC, exhaust, and SAFC should be ok up to about 12 PSI. After that you could go with the 720's. Remember, 12 PSI with the exhaust and IC will be much better than 12 PSI stock.

Yup, but 12 psi from a T04 would be even better! https://www.nopistons.com/forums/pub...1047683785.gif
