[turbo98eclipse]

hey i was looking at this....http://www.slowboyracing.com/more.php?id=4939&mods=36-7055,45-7053,46-7049,60-7060

and wanted to know what the "$100" upgrade was....im not THAT good on recognizing parts like these and also...what would be the advantage/ dis-advantage of porting/not porting the inlet/outlet of the turbo? (i.e.- whould would i port say...the outlet and not the inlet... and vise-versa)

well to answer the $100 upgrade part, they are a 6-bolt oil return line and water feed line and the bolts for them, they are not needed if you don't mind tweaking the stock water lines and shaving the edges off of you 2g oil return....

as for the porting, main difference you will see is a faster spool for one thing as well as making it easier to control boost....

hope that helps...

Have the turbo inlet port matched to their exhaust manifold. Depending on which o2 housing you run, have the turbo outlet port matched to the o2 housing.

I don't see why you couldn't port your stock o2 housing and use it as long as the turbo's wastegate is welded shut. Air flow should not be affected since you have an external gate.
