Let's talk chips and injectors...(for m30's)

[george graves]

What are you running?

What do you recommend?

What kind of improvements does it make?

[bmw335isturbo]

What are you running?-e34-335-Jim C chip

What do you recommend?Jim C chip

What kind of improvements does it make?-it runs the motor little rich and 7000 RPM's if you do some work on the intake side and hold on.

[MrK]

I don't know if this qualifies as a 'chip' per se....

I'm running an SMT7 piggyback on my 335i, and I noticed that pushing an 8 degree advance over stock across the board REALLY helps accelleration, and I also noticed that the m30 gets a little lean upwards of about 5000rpm, so adding fuel at that point gives noticeable gains.

I'm not sure who this helped LOL.

What do you think about running 19# mustang injectors?

[MrK]

AFAIK m30s come with 19s stock don't they?

What do you think about running 19# mustang injectors?

I had those... Bosch Type III. Really great injectors for only $60 bucks...



What are you running? 30lb injectors

What do you recommend? 19lb for N/A M30 Bosch type III

What kind of improvements does it make? my 30lb injectors are good for 300hp, but I had to turn back my AFM about 25 clicks tighter (leaner).

For a N/A M30, I would do no more than 19lb injectors, unless you are doing free flow exhaust, KN air filter and MAF, you won't notice much of a difference with just the injectors and a chip (unless maybe you want to do a markD chip, which would work BEST anyway with intake/exhaust/cams..etc)

I'm still sourcing parts for my M30 swap (almost done atleast), Im going to run a 059 ecu from a e28 535i w a dinan chip in it (have that already), w e34 M5 3.6 euro headers, no cat and a k/n cone filter w a fabricated cold intake. I have 19lbs inj(w new orings) from a 302 mustang i was going to put on the m20 but i might just save them for the m30. what do ya'll think

[Garageaholic]

I think you got a pretty nice setup. 19# may have been too much for the M20... good choice going with the M30

[george graves]

Hmmmm...Not a ton of info here I see

Mye28 and bmwe34.net might have the answers I'm looking for.

Looking for a tried and true set up for the m30b35 - and what it really delievers.

[JPL]

has anyone tried the mark-D chips and compared it to the jim C chips?

Is there a dyno sheet comparing the various chips like there is for an m20?

Spunky, M5 headers won't fit an M30, the flanges are quite different since the M5 has a 4 valve per cylinder head.

damn you're right!!! DAMN damn damn...those would of looked so hot on my m30 :crazy: well guess im keepin the stock headers and fabricate the rest of the exhaust system. what headers would be best on a gen 2 m30??

[euroshark]

IE makes some bad ass 1 5/16" primary headers for the M30 and they are like $425... I'm getting some for my 6er once the money from my new job starts rolling in... lol

those I.E headers do look pretty good. Im already commited to buying the M5 headers I guess I could turn around clean em up a lil bit and put them back online to sale.

If you know a good welder you may be able to have new flanges made to fit your m30... Maybe?
