After much searching on evom for what the stock Evo X turbo was capable of and not seeing many 350whp + on pump examples i decided to bite the bullet and get a 20G compressor wheel and housing.

The conversion is made by Arashi from Nickel_Sport on ebay. The quality looks decent. The housing fits perfectly onto the CHRA. The wheel was a little tight going onto the shaft. Waiting to go borrow a friends in/lb torque wrench to snug it up.

OEM wheel on the left, 20g on the right.

The outlet on the compressor needs some port matching to the gasket. Will post pics of that tomorrow.

My 3" intake (reduces to 2.5" at the turbo.

I bought that 2.3L short block that a vendor on here had up for cheap. I now see why it was cheap. The pictures of it originally had pistons 2 and 3 at the top of the cylinder. Upon arrival i rotated them and saw some lovely scratches down one of the bores. No real biggie as i have my block that i can get bored.

I just finished getting all the carbon off the pistons and most of it out of the ring grooves. The rings were stuck in the grooves (guess because it sat) Because of the carbon build up it hid the fact that the intake valves smacked the pistons. Nothing major at the end of the day. (not bashing the vendor it was sold used as is) They are clean now with no high spots and new rings are on the way!

Sending my head up friday to Orlando to get a 3 angle valve job for some OEM Evo 8 valves and a resurface for an MLS. Block is getting bored end of August :)

Just have to decide now if i am going with MAP/ARP/etc regular studs and an OEM MLS or MAP/ARP/etc L19 or whatever studs and an OEM composite.

The deck will not be able to be resurfaced for MLS so i dunno if i could get away with spraying copper on one side. I will only be running 28psi max but want the just in case room.
 
Complete!

Need to get the actuator mounts welded on and i am golden. Though i think i am going to modify the mounting tabs on the actuator itself so i can have it closer to the compressor housing for a little more room.

The compressor outlet on the new compressor housing needed a little gasket matching.

Did a little work on the short radius elbow (not that the outlet needed smoothing but i don't have anything more to really do at this point and its supposed to all add up right?:eusa_think::facepalm:)

The intake also needed a little work on the transition.

There is a small lip (about 1mm) between the intake and the compressor housing but i refuse to take a dremel to that and i don't have the means to build a jig to mount it to a lathe so its the best i can get at this point.
