Dinan Throttle Bodies for E46 M3

[maupineda]

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.

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..

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?

There are a few people who can bore the throttle body and I've reached out to the SCCA for clarification of using other vendors who can/will bore them with proper plates.

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

Is there something special about the Dinan housings? Can you not just bore out stock throttle bodies the extra 2mm and then tune? What issues might this present other than potentially being against SCCA class rules?

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.

Is says they're available on the Turner site?

Nice would love to hear it.

YES in your case it will help for sure. I would have loved to get them because they look sexy BEFORE being installed, but then common sense kicked in LOL.

I'll keep an eye out for you.

That is nuts for a 1bhp increase if that LOL
