Good info. I was just looking at this turbo. I think an EBCS would help you as would a STI intercooler. Both are upgrades I got cheap, though Im just running an STI uppipe and stock inlet.

Yeah I was able to get it on slightly more but the inlet and aftamaf didnt want to meet up correctly.

I think if I would get a big topmount/ebcs/sf intake it would improve spool bigtime.

Actually the PE 1818 uses the p18 housing in vf30 / vf34 / vf39, etc.
The PE1820 uses the vf22's larger p20 housing.

While difficult to verify, I suspect the internals are a MHI 18G.

That makes sence! I've been trying to dig info on this turbo for awhile and I knew people kept referring to VF34/VF22... now I know why. I'm almost starting to think that its a 1820 because of the late spool lol.
