Dont these turbos all have the wastegate built in? if so how do I get around that for external wastegate, Weld it shut? Will a standard 5bolt flange bolt up to it?

 

also can the exhaust side be swiched out for an T3 .63 or is it bigger then that?

 

Some have wastegates, some don't. Weld the flapper shut, wire it shut, just shut it somehow unless you like 20+ pound internal gates.

Bullseye performance makes a .63 housing for them, which spools super quick on an H22 but doesn't seem to choke it off at higher RPM. FWIW.

 

Well I have a T3/T04e with a .63 housing can I use that?

& a link to Bullseye performance? I can seem to find anything direct on google

 

No, nothing interchanges between a holset and a garret. The downpipe flange is different, you can get on on egay though. There is even one that comes with a threaded hole with a bolt going through it to hold the wastegate flapper shut. I would rock the stock turbine housing if it is a 12cm before spending the money on a bullseye one.

 

I agree, 12cm should be plenty small to spool on a GSR.

 

the bulseye and the stock unite are the same ar about .63

Holset will spool up just fine on a 1.8L. 4500~5000rpm

It does run an internal gate typically(factory set about 18~20psi), you can unbolt the w/g actuator and tack weld the flapper shut and it will work just fine with an external w/g...I had no trouble controlling mine with an old Tial 35mm gate.

It's f*ckin heavy tho. the turbo alone weighs about 38lbs....typical garret t3/t4 turbos are about 1/2 that.

IT's a super effiecent turbo that will make gobs of power, but make sure you've got a sturdy *** manifold hold it up. I went through 2 manifolds($90 modified SSAC and a $900 One-Fab) before I just straight took my hx35 off.
