Schwitzer S200 Opinions?

[QUOTE=2manyhobyz;1113961]
HT18S-2S.... Turbo from and FC Rx7.. Funny you should say something about that... I got to looking at it the other night and, the compressor wheel is remarkably similiar to the S200. Its the close to the same size but just a pinch smaller as far as exd and ind measurments go. What is different is the # of blades.. It has less..
So here are some pics... Going to modify this manifold to take an external wastegate and add allot of support. Got this for cheap on ebay... Didnt want to spend allot if this falls through and turns out to be ***.
Go for it. Support it well, see how it goes. You will also need to support the down pipe off the trans then a flex piece. Less is more. What's the compressor housing lying on the floor in the one pic?

This turbo should work pretty well once it spools. It should be comparable to a 2871R in flow. Big turbine wheel will be higher flow up top with slower spool but the 0.64 housing will bring that down.
Borgs are always odd in sizing compared to garrett, but they work really really well.

I don't get the logic of going with an eBay manifold, even for a test, if you plan to go turbo eventually. Here's why:
eBay manifold: $100
Approximate value after cracking: $15
After you decide you need a quality manifold and buy a new one, new BEGi mani: $400.
Total cost: $485
VS
new BEGi manifold: $400
Total cost: $400

Those early s4 / ebay manifolds are prone to cracking as they use 1mm thick tubing. This is a pity as otherwise the design is pretty great. AC, PS, stock coolant compatible, room for a 3 inch downpipe and a decent collector design.
It is possible to beef them up by adding braces etc but it kind of defeats the low $ theme.

It has been said many times before but worth repeating... Mr. Ebay why not increase the wall thickness?

FWIW, that was a turbo designed for a small diesel application, just by the specs - very small compressor inducer with relatively large exducer and disproportionately large turbine compared to the compressor.
