Dinan Throttle Bodies for E46 M3

[Feffman]

I have the Dinan set. Was able to get it on eBay like 2 years ago for $1,500(?) I think. They come up every now and then there + MPWW. Or you could do this as an alternative: https://store.vacmotorsports.com/vac...s54-p2430.aspx

Advorsor, I'd like to visit with someone who's running the bored VAC t-bodies. VAC lists them as "V.2", almost insinuating these are a second generation version. Was there a previous generation which they upgraded?

Anyone running the VAC enlarged throttle bodies, who'd like to jump in?

Someone is inevitably going to come in here and talk-down VAC products. I personally never had a problem but YMMV. I don't know anyone who has these so GL there but its really just boring out the TBs. I would think they are competent enough to do that..

Is not the closing plate also custom to seal the TB? Though simple in principle I am sure is a precision job. But I would think a proper machine shop would be able to do it to spec.

I called Dinan directly and they no longer produce the-t-bodies for the E46 M3, nor will they do a one-off single set or group deal.




My new racing S54 has head work, larger cams, exhaust, etc. to run to 8,500RPM (ish) so the larger t-bodies will help with a bit more than 1HP, I hope. SCCA just approved the larger ported bodies for class T1 for the S54.

It won't brotha.

A number of us have tried this out about 9 years ago. Full built heads, ssv1 systems, cams, etc... 3-5 hp is the result when dynoing only the TB difference back to back.

That would be great if we could find a good source who can do the job to Normal M3 TB's.

VAC can do them. I'm sure you guys can get a group buy going. It would be better just doing a GB for Stage 2 head or something. About the same cost and more benefit
