Default Weird *** T25 Flanges

For anybody running a T25, were did you get the two flanges for the compresser housing? Is there anywhere that sells then all ready welded to pipes or do you just have to buy flanges and get them welded yourself. Also, I know there are some of you that just did the whole SR20/DSM T25 Frankenturbo which bypasses all thoes flanges. Which would be better.

My SR20 T25 required a 3bolt compressor outlet adapter, got it off ebay but they can be had at the dealer as a 300zx TT part as well for like $8 i found out later on. As for the 2bolt style, i would just buy the flanges and weld my piping to that flange directly or a short piece and use a coupler.

It all depends on the A/R of the wheels you've got. 2G DSM T25's are a .48a/r compressor housing. The typical SR20det compressor is a .80a/r... ie, housings not compatible. I love the 2G compressor housing as the inlet is 2" and the outlet is 2" but also incorporates a J-bend in it which makes routing to the IC a snap (providing you don't have A/C or PS.

I believe my .48/.49 Garrett turbo (where I sourced my turbine housing from) that was advertised as an SR20det turbo was actually off a CA18det. Those are even harder to come by.

It's good to know that the compressor adapter is actually a cheap stock part though.

There is a few CA18 T25's on ebay. Maybe I'll just pick up one of thoes insted. My buddie is upgrading his T25 to a GT28R off his SR20 and was going to sell me his T25 for really cheap which is why I impalse bought that BEGI manifold and downpipe adapter. Which then forced me to buy a 1.8 engine for my miata. Which in turn forced me to buy a Flying Miata 1.6 to 1.8 engine converson kit and a Flying Miata 2.5 Downpipe. I just droped like 2k in the last week. Excause me while I go vomit.

Man you need a serious pat on the back after that, jesus.
Just think ahead, it might end one day and you'll have the car you've been working for all this time.
But then again the build never really stops does it.
