Hi all - Welcome back for the second time this month!

I apologize for the inconvenience of the site being offline. The site was down for technical reasons, but it didn't help that I was of offline for two weeks (camping and travel). Once I got back, it took a while to get things sorted out. That's resolved, and the site is now back up. Huzzah!

Please take a minute and read the Site News thread I've posted in the General section, and feel free to comment. Thanks!

OK I really need help here. I finally got the upgraded TB20 kit from Jason at Turbo Engineering. I keep thinking a gasket should go between the housing where the down pipe attaches. I have attached a pic showing the area of concern. Jason from TB Engr says no gasket required but I'm not quite sure as this might produce an exhaust leak. Please moderators comment.

Just to add more info in reference to the pic. Jason of TB Engr mentioned that these two surfaces would bolt together metal to metal. I just no getting a good feeling on that.

If both surfaces are flat, the two pieces are rigid (such as cast iron or steel), and they are made of the same material, a gasket is not always needed.  I have worked on several different vehicles that do not have a gasket in the location in question.

Wow, wouldn't excessive pressure cause these surfaces to crack or give an annoying exhaust leak?

 So long as your both on the same page. I think the phrase " Jason from TB Engr says " sums it up Wink

Yeah I'd say try it and if it develops a leak go from there. There are places that offer custom gaskets, you could get crafty and make your own, or order the right one.

Does look from the pic that there was  a gasket previously.

From what I gather it must be OK for a metal to metal contact? I used the pics on the LC engineering similar kit for comparison. It appears a gasket maybe included.

I should also say I haven't fired it up yet. I'm still in the install phase. I have a rebuilt RTE long block going in and the turbo kit going in next. Just checking fitment

Connections are always the first place to fail.  What would it hurt to throw in a gasket?

Isn't that a normal 5-bolt T3 wastegate gasket?  They are just a few dollars.  I would install one; not worth the trouble of having to tear it out again to fix an exhaust leak.

I'll think I'll throw a gasket in. Where is a good place to pick one up?

The gaskets are all over ebay, but it's safer to match one up at an auto parts store.  They can probably "get one from the warehouse."
