Sometimes the old Dinan ones pop up in the classifieds, I think they are 59.75mm

Reading about bigbore tb's generally left me with the impression that they'd be more of an icing on the cake thing after extensive modifications, and generally the impressions posted on NAM on older posts have not inspired me to seek out adding one...

" I did the Dinan TB early on in order keep my waranty in tact, and as far as bang for your buck it's really low on the scale. I'm still using it with no issues and feel that it works pretty well but only because of the rest of my mods and the benefits are only noticable from 5500rpm and up, and you will lose some power/torque in the mid. areas of your rpm. Basically if your not running a head and exhaust for the car to breathe better and a raised red line so your shifts put you into the higher rpm's in your next gear you're shooting yourself in the foot. And even then the gains, if any, are questionable.

(If mine went bad I'd just go back to stock.) "

I have done tbody upgrades ( or tried them ) on every motor I've modded. Sometimes they help a lot sometimes they hurt the performance . In my instance, with my extra air flow I have i feel like opening up the tbody and intake manifold alittle might give better up high power where these lack.. my car has MORE THAN ENOUGH down low grunt and honestly thats where its getting used the least so if I can more Uptop thats what I want and in my experience a bigger tbody usually helps that..
I checked out that one linked but then I'd have to buy a stock one and send it out to be reworked and that I could see taking months as it's across the pond and C19 has everything the pace of mollasis
