all done i've put about 2k miles no problems yet besides my clutch
so i did the m20 flywheel with sachs h.d. clutch
idles perfect runs strong i have it at 8 psi good numbers on the wide band 14.7 idle 12.3 under boost i bumped it up to 10 psi but leaning out so waiting for my Miller Performance W.A.R. chip

Awesome. This is almost exactly what I want from my car. Definitely want to take oil from the filter canister. Interested in the W.A.R. chip too.

Pretty easy to set up the water injection? Did you buy the kit new?

Very nice set-up! and inexpensive as well. Please keep us posted on any further improvements, although it appears that it is nicely dialed-in already. Congrats!

So is all your fueling just being handled by the 30lb injectors and the stock ecu?
Title: my low $$$ turbo build
Post by: 318e30 on July 01, 2010, 11:59:48 PM
yeah stock ecu, 30 lbs injectors & fmu i have a fuel pump i need to install next.
i got the water/meth. used on eBay $150 this is the 3rd Snow performance kit we've gottin off of eBay they work awesome !!! new $350+. the kit is so ez to install it activates off of boost.

one more thing is i kept my A/C on the car i love it next would be 3.73 lsd

Can you give me some insight into how you got your car to run on 30LB injectors by simply swapping out the stockers

Also do you have the part # of the injectors

thanks

He's got an FMU... I'm guessing a vortec unit as they are the most common

m50 manifold? more info? where did you get it? i don't know much about those...
Title: my low $$$ turbo build
Post by: bmwconnect on July 02, 2010, 12:48:01 AM
Ahh yes I was thinking he was just using a rrfpr alone but now I see those kits and they come with adjustable unit also
Title: my low $$$ turbo build
Post by: 318e30 on July 02, 2010, 01:09:14 AM
Bosch # 0280150785 96 turbo volvo 850 i believe
it runs perfectly fine with stock ecu, 315cc & FMU my car has 178k miles i just drove it to Laughlin NV. from Fontana CA used up 1/2 tank thats 250 miles 1 way going 80-85 mph thats about 35+ mpg
Title: my low $$$ turbo build
Post by: 318e30 on July 02, 2010, 01:15:43 AM
yeah you can use an adjustable 1 like jackson racing, bell eng., cartech or somthing of that nature theres a ton of them out there
Title: my low $$$ turbo build
Post by: thedguy on July 02, 2010, 02:08:29 AM
wait... You wouldn't happened to have been to Adam's in recent history talking about turboing a 318 would you?  Mind pm-ing me your aim address, I'd love to talk to ya there.

yes I just wanted to get the point across that you can't simply swap in 30lb injectors and the ecu magically compensates for them... you have clearly lowered the fuel rail pressure
Title: my low $$$ turbo build
Post by: 318e30 on July 02, 2010, 11:20:32 AM
i havnt touch my fuel pressure other then the fmu ADDING fuel pressure under boost so the ecu will compensate for the amount of air. just to put the point across. everyone running 24 lbs ive seen have been leaning out @7-8 psi

Those injectors you have put in are flow rated at 29LB@57psi... That mean's that your at a flow rate of 24LB@43.5 with the M42 at idle... If you were to swap in 30LB@43.5 rated injectors the car would simply not run. Motronic can compensate for a maximum flow rate of 24@43.5psi  injectors MAX~

Don't believe me ?
Look up your injector part number here

Title: my low $$$ turbo build
Post by: 318e30 on July 03, 2010, 01:42:11 AM

ebay m50 turbo manifold i got mine for $120 shipped you cut down the last two cylinders & cap the end
(http://i73.photobucket.com/albums/i201/mazdamx-8/2010-05-05170808-1.jpg)

then make an adapter to let the turbo clear the valve cover

Sorry to hear, atleast you were having fun at the time :)
Looking on the bright side, now you have a perfect excuse to buy some low comp forged pistons, and up the boost some more!!

You mentioned the use of the OBX manifold, from what i can see they are for the e36's? Would they fit e30? As in would the turbo clear the shock tower? Im very close to buying a manifold, and as good as the 666 look im just finding it hard to part with close to $1000 (adding postage to Australia).

Post by: 318e30 on August 21, 2010, 12:17:12 PM
The fmu is most likely eBay I got it on Craigslist years ago

The turbo manifold is a eBay m50 cut down bolts right up

Yeah gonna do a mild build now rods, wiseco rings, cometic gasket, acl race bearings, regrind cams turbo spec, & tuned
Title: my low $$$ turbo build
Post by: thedguy on September 08, 2010, 12:54:53 AM
damn man!  No wonder I haven't seen you at Adam's.  I've been rethinking if I want to go boost and I think with my 200k motor I probably should ;)

Just keep it low boost should be good lol
