WHAT SIZE INJECTORS AND MASS AIR?

[89stalker]

I recently bought a p600 and wanted to know what kind of injectors and what size you other guys are using. Also what size mass air meters are you using. I have a 75mm pro flow and 24lb injectors now and i was told that this wasnt enough. Thanks

This really depends on a few factors....

How much boost you gonna run??
Do you use a FMU???
What are you goals, H/P wise and boost wise?
What's your current combo??

My mods are cobra u&l, 75mm pro flow, 24lb injectors, cam, tremec trans, msd ignition, bbk headers to flowmasters. It is a p600b with a 2 core cooler and a 14 pound pulley. Thanks

36's may just barely work for the 14#'s, you may have to go with 42's to give you enough "play" room. Do you have any other fuel system upgrades??

[89stalker]

I dont have anything else. The kit came with an fmu. Should i get something else? Thanks

What size fuel pump you running??? You're gonna need a larger than stock pump (volume wise), alot of us run the Walbro 255 in tank, some of us run an additional in-line pump as well.

I dont have a bigger pump now, but will invest in one. Also what mass air should i use?

Pro-M 80 shorty, if you plan to have your car tuned check with the place that will be doing to see which calibration they prefer/recommend. Alot of tuners prefer a non S/C'd meter vs. a S/C calibration meter for ease of tuning.

What do you think i should do, use a walbro like you guys? Also what size maf meter are you using? Thanks again

Walbro is a solid performing quality pump and you can pick up a 255 liter per hour one for around $100.

As far as the MAf goes, I prefer the Pro-M 80 mm meter. If budget is tight I think a 75mm would serve you well.

I already have a 75mm pro flow, will this work if it is recal'd?

[5150 LX]

If recal'd, yes.

[89stalker]

Do you know where and how to get it recal'd? And how much it costs. Thanks for all of your help.

$109 plus shipping according to their site

Here's the recal sheet you'd need to send with the meter.

You could sell your meter for about $100 on the Corral or here and then pick up the 80mm unit for about $200. You've have a better meter for about the same cost.

I found a pair of 42 injectors off of a 96 gt, will these fit mine?
