Skunk2 68mm billet throttle body - JUNK!!!

I bought one and attempted to dyno test it...it was the biggest pile of crap ever. I looked nice, no doubt about that, but functionality-wise it was awful. The first issue we encountered was the TPS sensor not fitting; talked to Skunk2 and they blamed their manufacturer and sent some adapter spacer thing. Next, with that adapter installed (as a side note, the little TPS bolts included wouldn't thread all the way in so we had to tap the hole deeper), we did a boost leak test (never got above 2psi on the tester) and air was pouring out from around the TPS...Skunk2 didn't use a shaft seal, just a bearing! Next, after slathering the TPS with RTV so it would seal we did another boost leak and now the other side where they supposedly did use a seal was leaking really badly too at less than 5psi! We decided to dyno test it anyway to see what this thing could do. We did port the IM inlet to 68mm. Start the car and it would barely run; great. We then confirmed the TPS was set to spec; Skunk2 provides one spec but its not correct according to Mitsu, eitherway, we tried Skunk2's spec and Mitsu's OEM spec; car still idled like crap. We adjusted the BISS to no avail. In the end, we could never get the car to make a clean pull due to issues from this billet paperweight. A few days later I installed a Mil.Spec 65mm ported throttle body and the car idled and ran perfecly with zero boost leaks. After much argument and denial that the product was faulty Skunk2 finally issued a refund for it.

I don't know what the official policy is, but talk to the shop you got it from and I'm sure they'll be willing to refund you then they can deal with returning it to Skunk2.

had the same problems. although make sure you look close on your stock intake manifold... you can't actually port it out to 68mm. the sidewalls are not thick enough to have a true 68mm inlet. i know this cause my die grinder worse a hole through one, hahaha.

Well, the good thing is that you tested it out before anyone bought more, thanks.

We actually did get the full 68mm, but the wall was incredibly thin so we welded on some extra material and sanded the flange flat (just in case it warped from the welding/grinding heat). Thanks for the heads-up, I forgot all about that until you mentioned it.

Not the best move for a company trying to make it in a new market!

So what are you going to do with it now?

I have a 65mm Mil.Spec ported throttle body on now; its not ideal since there is a 1.5mm step all around the edges, but I'm sure its not really making a difference.

I meant what were you doing with "it" now, meaning the Skunk T/B?
