Talking Success for Turboed 325

As some of you know I have successfully turboed my car. And unlike most people I'll share my results of doing a one off setup. For starters I'll just post pictures (not all are here but ill add some more later), then answer any questions that you have.

Keep in mind this is over 2 years of different configurations

Post up all the info you can, sick project. Did you fab the kit yourself? Who did the tune?

If those are the #'s in your sig, I'm really impressed.

Thanks! I did fab everything up except the exhaust manifold. I had a tuner in LBC hold my hand with the tune.
They are real numbers see video's below




Current parts:
-SPA manifold (want to make my own, ask if interested)
-precision 6266 (rated for 700+ hp)
-Precision FMIC (rated for 700 hp)
-38mm china WG (want to go bigger, ask if interested)
-2.5" charge pipe
-Turbo XS RFL bov
-Pro EFI basic kit ( EMS, patch harness, wideband, fuel pressure sensor, boost solenoid, and map sensor.)
-AEM wideband (so I can have a gauge in the cabin)
-60lb simmions injectors
-255lph fuel pump
-fuel lab FPR
-aeromotive fuel filter (10 micron)
- VAC oversized HG just .040"
-raceware headstuds
-ebay catch can (deleted all traces of oil separator, JB welded air distributor holes shut)
-scavenge oil pump

I may have left something out.. but for the most part thats it

Wow very impressive if those numbers are true @ 352whp. My hats off to you that you did all the work yourself and fab'd everything up. Not an easy task especially it being a 2 year long task. Glad you stuck with it though, lots of trial and error paid off. I know you can't expect the car to last very long though on that un-built (correct me if I'm wrong) motor. Also, any future plans? GJ and GL with this ongoing project man.

Thanks! I really didn't have much support especially on forms, everyone ether told me I was going to blow my engine or I should just get a m3" Mostly I had to figure things out myself. It truly depends on your goals.

Your right, thats with flux-cored MIG on crappy power. Now if I had gas, and a TIG it would be beautiful welds. but since this car was my "project" car it gets the job done, and works fine.

Yep haha. I believe theirs only one other person running pro EFI on a non-m.

I didn't see an option on Pro EFI's site for a non-M. Was your harness a custom build? Is the Pro EFI easy to install? How difficult is it for a local tuner to get spot on?

Your right, but the M3 DME is the same pin out as the non-ms It was straightforward install if you know what your doing, it can take 2 hours. Pro EFI has dealers all over the US. I'll admit that my tune is not 100% only because im the ONLY guy with a pro efi on a 325 therefore Jason has not spent the time to get everything to talk to Pro EFI via BMW's CAN network. As it sits my idle is erratic because of that. but theres other ways I'm currently exploring to possibly fix it, via run a MAF or letting Pro EFI control the ICV.

congrats on doing this. I love seeing people thinking outside the box and doing things for themselves rather conforming to the absolute garbage people spew on here about not being able to do it without Nick G.

one person says "get a m3", another says "can't be done", and everyone else just repeats what they hear, even though they don't have any real clue of what they're talking about.

having said all that, I know this project has taken quite a bit of effort and your time so I do have a question. looking back at everything, would you still want to build it all over again, rather than getting the TT kit which makes torque a lot sooner, can be bolted on in your garage in a matter of a weekend, and still has a functional check engine light? I ask because if you think of all the time and research it's taken you to accomplish something that still isn't finished, there must be a part of you that wishes it had all been simpler.

Thanks! as-far-as going back and doing it again, you mean having the knowledge that I have now? If so, I would have started with an M3 ONLY because I want alot more power now. But at the time I wanted 3-400whp and that I accomplished. I still would have not gone with the TT kit, as for one he doesn't support 325's... and two there are no safety features for the stock DME except using the stock knock controller. what if you had fuel issue, or tweaked with your setup, then u'd have to get someone to tune it again.

when you mentioned "still has a functional check engine light" I do, infact the ONLY code I have right now is for the MAF simply because its unplugged, but could be fab'ed to fit in the charge pipe (need to fix oil on charge pipe 1st) or i can get a MAF simulator via Pro EFI that will take care of it.

TT kit is for people who only want to touch it once, not constantly tweak. Only reason why the torque comes on quicker with his tt kit is simply because its a smaller turbo. I'll admit my turbo is to big for what the engine can handle, and I should have gotten a 58mm turbo, would be perfect especially if I run 25PSI + were the turbo gets into the efficiency range.

Back to "get the M3" now I'd only consider it depending on your power goals, and what economical for you. Since I'm at probably the max my internals can handle any more power I put down is gonna cost me ( build engine, heavy duty clutch, LSD etc.) But since I want MORE power the M3 is looking more attractive, as its a 3.2L (can spool larger turbo quicker) it can rev to 8.5k RPM (again helps with spooling large turbos) it already comes with an LSD, 6 speed, and there seams to be more aftermarket parts for high power.

While the non-m, if I want lets say anything more that 800whp, I'd have to upgrade the head for sure, get a whole different oil pump so I can rev to 8k (w/out it disintegrating it) plus getting a LSD, and built motor. (usually non-m performance parts are more money) So I have to tally up the cost for both, and see how much it will really cost.

.040 or .140? What fuel are you running at 20 psi with your current setup?
