how much for an H cover ? ?

[XxDarkSidexX]

so how much is an H cover??

I just got a turbonetics t66ptrim,dbb, with an S cover on it; How much would it cost to buy an H cover with an .75 A/R ratio with the 4" in and the 3" discharge?? Thanks.

It will not bolt on it uses a different backplate

To add more to what Mike just said, each turbos' backing plate and compressor cover is machined to exacting tolerances for each compressor wheel. 9 out of 10 times the turbo would need to be sent in to PTE to have a modification like this done. This is due to the differences in compressor wheels used between the two companies as well as chra compatibility between a T-netics bb cartridge and a PTE DBB cartridge. Not only to mate up to the compressor wheel that will be used, but also with regards to how the backing plate bolts to the chra.
They might be able to retrofit your existing 66bb turbo, but you would have to contact them and they will need to have your turbo first before being able to say yes it can be done or no it can't
Hope some of this helps.

thats what I was affriad of; Well thanks for the info; mike and patrick. I have to thank patrick for the pm's answering ALL of the questions I threw at him, and being open with discussion about turbo; and MORE then that sharing the info he' has spent a long time reasearching and now has shared that info. He made me a turbo trim expert in a matter of a few pm's. So much so I have unfortunatly told someone their thought to be Q trim isn't a Q trim at all, in fact is a P trim(due to THB-5-76 trim on the exhaust housing) and he is glad I told him because if he went to sell his turbo on the board he might have had a undeserved problem. Thanks again patrick for sharing the information on the turbos. I figure Im good on the turbo info for another 2-3 years

Was that exhaust housing you are referring to, on a Turbonetics turbo or a PTE turbo?

his was a pte unit; also I found this to be weird. It looked like a pt67 with and E cover (3" in and 2" out) but the discharge was ported to 2 1/4". But on the exhuast housing it said THB3-76 or THB5-76 i can't remember which.
