430hp per turbo, I'm running twins which combine to approx 850hp. These turbos will make 600whp on pump gas easily, and 700+whp on E85. The inducer is 47mm and exducer 63mm, same specs as the GTX2863r. The main difference is that it's a billet 7+7 blade wheel verses Garrett's billet 11+0 wheel. I specifically want the 7+7 because it has better efficiency when running at lower pressure ratio.

I had some time this evening to finish up on the intercoolers. Not the prettiest welds since this is my 2nd time welding aluminum but I made sure the welds are leak proof.

They look pretty good to me for only being your second time. Nice job

Thanks! I'm working on a steady hand for more consistent beads.

Nothing too crazy today, got some time to test fit the intercooler and plumbing. I'm going to bring out the front crash bar by 1/4" using aluminum spacers to give the IC some more room to play with. Currently the 3.5" core barely fits in between the crash bar and radiator support. I'm thinking of mounting the IC with the bolt holes circled in red. It's too bad that I have to do my work outside since the one car garage is currently occupied by the welder and tools. Winter is going to kick my *** real soon.

I'm still thinking of where to relocate the powersteering cooler to.

It's a good day out so I've gotten more progress. Figured out how to relocate the OEM powersteering cooler without making any major mod. I simply switched the OEM brackets around and that allows me to place the cooler inside toward the AC condenser out of the way of the IC. Extended the lines with 3/8 hose and refilled powersteering with DEX VII ATF.

I also got the IC brackets welded on.

Got all the post-IC pipings sorted out. Still need to weld on MAF adapter and BOV flange.

Test fit front bumper
