BEGI FMU FPR discuss.

Ok, first, does it eliminate the factory FPR?

And do you think it would be a good idea to turn the boost up to 9-10psi, With this,walboro pump,new injectors stock ones? And i have a shitload of other supporting mods btw.

Or should I just go EMS, either way I still need a new fpr,and injectors
 
It does not get rid of the stock FPR, it works with it. The BEGi RRFPR is installed between the stock FPR and fuel tank.

You don't need any of those to run 9-10 psi. Stock FPR, pump and injectors can handle that so you'll get plenty of fuel.. it's the airflow you wanna worry about. 3" turbo back exhaust, intake, front mount intercooler, and a solid BOV should be your priority if you wanna boost more. Solid engine mounts are a good idea as well.

And you don't need a standalone EMS either, not with the stock turbo and stock internals. Get a SS AFC instead, it's a lot cheaper and good for up to 16 psi.. which is about the peak of the stock turbo and WAY above what the stock rods can handle.

Well no, I have all the appropriate mods,injen sri,hiboost fmic,ported thuner mani,atp wga,greddy type s bov,pnp stock s-pipe,2.5in. hiboost downpipe to stock cat-no exhaust at all after it, and my turbo is not stock it's mpnicked
T28R internals pnp I/E sides. Plus weight reductions, and maybe I forgot a thing or two IDK.

I need new injectors and a fpr anyway.
So I'd need the begi unit and a new stock fpr, and injectors?

Only stock parts on my car are InMani,Engine,Trans,Ecu.

The whole point of me turning up the boost safely(ha), is so I don't have to buy an EMS and get it tuned and all that crap.
 
I'm not following why you need a new FPR and injectors..?

And your exhaust ends after the stock cat? Why not get a high flow? And the BEGi isn't gonna do you any good, I had it in my auto P5 when it was turbo and it worked for stock boost.. but it maxed out the fuel pump at even 7 psi. Even with a better fuel pump such as the Walbro it won't be as effective as the SS AFC.

Highflow midpipe, maybe 440 cc injectors since you're very set on bigger injectors, and SS AFC will do the job for ya. A good boost controller is a must tho, you don't want it spiking and blowing your engine.. especially with a T28 compressor on that turbo, you'll be pushing quite a bit more air than 9-10 psi on a stocker.

I have and have had for the longest, a CEL for too much fuel. So it's gotta be either thr stock FPR or maybe one of the injectors is getting stuck.
My check engine light will come on for a few days, then go off for a few days.

I was told, it's gotta be the fpr,injectors, or possibly a loose ECU wire, since I used to have an MPI a long time ago. and I think I'm the only Msp to have a CEL for too much fuel, with a stock ecu.
 
alright, so I'm better off with new injectors maybe 440's or stock size, new fpr,new pump, and the AFC.

I just wanted to see if this Begi unit was any good.

And I haven't got a highflow cat, because I'm waiting on that true 3in. s-j pipe, then I'm gonna weld a 3in highflow cat on that and put the sensor after it, no exhaust after the sensor. Just like my set-up now.

The SS afc will control the injectors. So when you data log and check your afr you can tune the car to the max. The stock injectors are good for about 230 hp. If you want more power then larger injectors are needed. Plus the SS afc will handle 440's
 
Yea. I want the AFC, as for ems. But now I gotta save up for these parts and I just got fired.

So now's not really the best time to be buying all this stuff yet. Thanks for the info though.

Plus, I'm buying that head off you ogsp5, so for now it's just adding a pnp throttle body and pnp head. Little by little.

Wish I could buy that block off you too, but I don't got enough right now.
 
No I'm gonna hold off on the ems and other fuel parts,until I get a job atleast.

I'm doin a built head and ported TB next.
 
No need to do the FMU if your running an MS ECU. You just need to stay conservative with the boost. I'm running 8psi after seeing how lean I was getting at higher boost.
 
Yea, I mean i could turn the boost to 9psi which is all I want(I've tried it, and with my mods it pulls so hard.) Plus i baby my car, I don't race often, I really don't even use 1st gear. I only race from 2nd gear rolls and usually end a race after 3rd. So my car should be fine, theoretically. So maybe I could get away with it at 8-9psi.
Right now, the ATP wga just boost whatever it feels like that's why I need to steady the boost with a boost controller, I have one, but never installed ever.

I just wouldnt wanna come back on here, talking about how my motor just blew.

So I'll just do the built head a modified tb for now.

but at 9psi it's so nasty, sounds pissed off lol. I only did it like 3 times at 9psi only after my turbo was modified, just to see how it felt since i was only used to stock boost,stock turbo,and with no boost controller the stock turbo was hittimg 7.5psi. It's easily as fast as a stock evo or sti at only 9psi with the mpnick turbo.
 
I hate to come in here picking you apart again, but why invest your money into the head when the rods are the weakest point of the engines. Forged internals should be at the top of your list.. then you can crank up the boost as high as you'd like..
 
Naw, I understand. I just don't plan on keeping this car too much longer. So I wanna trade it in still running lol. Or sell it running. on the street.
 
And a fullt built head is going to be a nice addition. Then ported tb.

Then I'll decide if I wanna go further and even keep the car.
 
so i need some advise

i've been thinking about this for a while, ever since i installed the 626 IM, my fuel pressure drops(instead of rises like b4) when i go into boost, also the car runs leaner, 12-12.5

i have the MSP ecu controlling the engine and running 7.5 PSI. can i use both the FMU and AFC? or is getting one making the other useless?

i have neither at the moment, but with the temp going down i really need to add some fuel asap

Long Term plans include a small build, run 12-14 PSI on the gt25, no meth or extra injectors
