Otherwise Dinan.

VAC parts if engine failure is the goal.

$4200 for 6hp. Let that sink in.

They used to be significantly cheaper.

Also, on a forced induction build they should shine more. I probably wouldn't spend the money on a NA car.

... and only at the top end-- deceased power at the bottom end

Wasn't there a service that would bore throttle bodies? Then you'd just need to get the butterflies made. I think they are brass? Shouldn't be too hard for any machine shop to tackle.

Well $2950 is core fee which is returned if you send your core in... I am sure you could buy a used stock set cheaper than that and send in if you wanted to have both sets and get it cheaper than $4200... otherwise it looks like its $1250 in labor and parts to convert, so most of the price is in the stock part as a starting point... but I fully agree with your sentiment.

Gees, that core fee is crazy. I guess it's about a third as ridiculous now.
