Ok, I should have went with 550's but i knew that some day I would want to go extreme so I bought 650's a few months back. Im going to install them on my AWD this weekend along with my walbro 255 hp fuel pump and an aem fuel rail. Also new fuel filter. I am currently in the process of looking for a afpr also. what would be a good psi to run on a ported 14b and o2 housing. Also would it be a bad idea if i didnt hook up my translator right away since im still learning how to use it.

any input will be appreciated. Im trying to get it ready for slowpony day and Im sick of looking at all my parts sitting in my room doing nothing.

Thanks,
Travis

You won't be able to run bigger injectors without some way of controling them.

turbohcar has a AFPR for sale.

Now as for hooking up the apexi. I would, just like AWD DSM said you are going to have to have a way to control the air to fuel. Hook it up!

AFPR
Eprom ECU w/ 780cc chip
780cc injectors
255lph HP Walbro pump rewired
GM MAFT w/ intercooler pipes setup

I've got plenty of fuel and tuning parts. Basically all I'm missing is a wideband. LMK

Didn't you say you were going to run a GM translator? If so then that will do fine. With a 14b, 550s will be more than enough. If you run into troubles with to much timing on the 650s, you'll want to turn the fuel pressure down to ~30psi and tune them like 550s. You won't want to go much lower than that though. The spray pattern will start to degrade.

Nate, I think he was asking how much boost he could run (psi). And to me it sounded like he wanted to run the 650's without the translator.

I didn't see the part about not running the translator. That will NOT work at all. You might be able to hack the MAF enough to get it to run in closed loop, but as soon as you went over 40% throttle it would bog under all of the extra fuel.

im going to run my translator I just said i need to further understand it. My ? was about the boost and fuel pressure settings.

on a 14b, 16-17psi is the most you will want to run if you want the turbo to last. Stock turbo fuel pressure is 38psi. I was suggesting to run 30psi because 650s are a little big for a 14b and might net you to much timing, causing knock. Like I had said before, I'll help you out with the translator tuning if you need to get a baseline.

ncgalant, the tuning god! I know I'll be contacting you once I get my heap running to get everything set up right! What's your going rate?

ill definetly be giving you a call probably sometime next week.

nate is damn good at tuning i need to get with him again to tune the galant some more

I don't know about all that So far my tuning has all been pro bono however you spell it. I'll be more than happy to continue at that rate as long as my financial situation is stable Anyway, I'm always happy to lend a hand as long as you fit into my schedule. Shoot me a PM. That goes for Mitsu and Trey also

You can control just about any (large) injectors with DSMlink... no size is too big.

My point was that you can't put larger than stock injectors in a car without doing SOMETHING. 650cc injectors in a stock car = way rich.

well it won't be that stock. And I know what you mean I was getting opinions on psi levels.
