ITB's on a 24v project, Dyno results Post 136!!!

I love being on guinea pig runs - let me know. I've got money set aside for the s50 car.

Damn you mike! Subscribed.

Ready when you are.

I have an OBD2 S52 e30 and would be interested in this as well since i am moving out of CA to a state that doesn't require smog ;D

We will be working on the obd2 coding soon. Just picked up a nice clean m52b28 we are going to use as a test mule.

Interested... for my obd2 s52

Not sure the OEM mounts are happy, but quick vid during a tuning session...

I know this is 2 months old, but...


Sounds like some crazy drop in a dubstep song lol

How much are the tunes for the open trumpets on an E30? I think I am going to put one of my cars up for sale so I can add this to my OBD1 S52 E30 track car... for realz

[ReSoP]

seriously would love to see what kinda of power curve these would create on a 3.2 ob1 setup.

I still want to see one of these setups on someone's m20.

the manifold outlet doesnt match the m20 cylinderhead port opening

[mikebloco]

Well at least there's RHDs tib setup. I'm still trying to justify spending 1,400 on the kit though. I know on yours "digger" that you went with the 40mm correct. What about 42mm tb's on a turbo m20b28

i use 42mm but when you work it out there basically is negligable difference as the trumpets are identical so its not 2mm bigger along the entire length. just buy the manifold portion and maybe the 50mm long extensions and DIY a fabbed aluminium plenum with single throttle body. keep it simple

[mikebloco]

I was thinking of itb's. Because I could run it na until I made the jump to boost

[digger]

IMO if you're realistically going to be boosted one day then id use a single TB

Bump for progress on this! I am interested for fitment on an E30 swapped M52.

Is there an airbox that will work?

We have parted ways with Jenvey, but that's not a bad thing. Rama at RHD has filled in that spot for us. :)

As far as the throttles in this post, they will be going on an s52 build, along with some TDC-paired (aka 180°) headers in a Bauer e30. The pistons were delivered today, but as far as fitment, we are a few weeks to a month out on that deal, and they will NOT be using an airbox.

The biggest hangup is the 24v engines take up more space, and decrease the available room to keep clearances around #6 cyl to keep that "bubble" around the intake clear. Realistically, the best scenario is to keep one throttle diameter of clearance around the trumpet. To stuff that inside an airbox, then clear the brake booster (or even master) si going to be a challenge.
