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

ebay m50 turbo manifold i got mine for $120 shipped you cut down the last two cylinders & cap the end

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

sorry, i completely missed this post. it has run mid 6's in the 1/8 on it's last setup with 2 cyl's fucked up. the new setup is trick flow heads and a bigger cam and not a hurt motor lol

do u have a link to the exact fmu, ur using. i attempted using the dasc rrfpr and it was worthless.
sorry to hear u blew ur motor. built it bigger lol.
also did u do all the welding yourself? how did u go about sourcing the gaskets u needed?

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).

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
