Minor Threat

Tunertoys.

I didn't like my vitara/Delta 272 either, I'm going with a Z6 head next season. The 272 pulled up top like a Z6/Y8 cam does, nothing super special and it was a pretty big dog down low.

272 grind is meant for all motor madness really. If you want a grind go with the 257 or 260 grind they offer



Also port work will help on boost alot more than a cam will. Also a mucho throttle body like a 70mm will give ya increased top end without killing the bottom end like a large cam will with no compression.

I'll definitely consider the 260 grind.

Port work is definitely in the plans.

Any tips for a basic port on the A6 head Chris? I would assume that the basic bowl port and short side radius would do the trick.

hog the ---- out of it


get rid of 55mm piece of ---- throttle body. BUy a 70mm tb from your favorite mod

JonDouglas

Haven't you had one for sale for a while now?

Chris, I assume that I would either have to go with a Skank2 manifold or cut the A6 up and make it work with a large TB. I have seen pictures of an A6 manifold that had the plenum vilume enlarged and an new TB mounting surface added floating around.

Guy-Fast

I have sold like 10 of them in the last 2months on here



Um a z6 manifold will hold a 70mm tb you just have to weld up the iacv port



or go with any aftermarket unit. Or even better go box plenum

JonDouglas

Thanks for the guidance man.

Do you literally mean hog the ---- out of the head? It is an A6 head after all and I will be using a spare head to do all this with.

Guy-Fast

yup the wheeze ripped pretty solid with the uber ports.
