Here's 2 pics of the engine compartment. Notice under the hood, the indents in the insulation, and the clearance holes that had to be cut to make room for the engine to torque upwards in front. Chances are, all R56's lift the same height, but when the turbo is oversized, it hits the hood. The O2 sensor cable also needed clearance --- TurboKits designed their catless downpipe poorly. Maybe someday I'll clean up the clearance holes so they don't look as rough. Also want to find a local shop to create a solid air inlet duct, between the MAF sensor and the turbo. All these hoses, clamps and fittings are not fun to work around.
Is the tuning solution smooth or just kinda works?Id like to do this swap my self but i dont have a DD so i will have to waite until i can off my race bikes so i can have something to drive around while i get it working right.
on the work! tough swap to get running rightHere's 2 pics of the engine compartment.

With my current 280 HP, if I was to add a WMI system, that would put me a lot closer to your 320, maybe even over. 'Course with no bottom end engine upgrades, the whole thing would probably be history in no time. But that's why I'm interested in this thread --- who's got experience with this kind of power, and how did they get there? And, I'll say it again --- the Garrett was a mistake! There's no way I'm getting any boost at 2300 rpm!
How much boost out of the gt28 btw?
I was beginning to think you built and sold without testing. Must have been a blast driving a package like that for 10K miles!

on the work! tough swap to get running rightIt'll be a lot easier to get a hybrid working, than a Garrett. Overall results should be better too. Boost controller set at 20PSI.

Okay, so disregarding the cast-off NASA parts, has anyone with cubic dolars really dived into this thing? Im not an expert, but Im thinking Moldex offset ground 1.7 stroker crank, forged Wiseco or Carillo rods and Wiseco hyper-eutetic pistons with high flow injectors, a hybrid turbo and a good tune oughta get the 350+HP cart rolling. As to price, well if you have to ask .............
So, who, if anyone, has really built one of these things?
Heck my stock Chevrolet has a nodular iron crank, forged rods, slipper pistons and a windage tray. Its just begging for twin turbos.
This is just an engine, not rocket science. Sounds like 2009JCW has a lot of these parts, how about at least some pix of the Viper engine?

Definitely what i want in the long run, less psi more power
The dyno chart can be seen on http://accessecu.com/dyno/ --- took them 3 hours of tuning after 2 hours of troubleshooting my build (had a couple defective added-on parts). The results are as smooth as the chart. I still throw a cel sometimes, when I get lazy and don't downshift to accelerate in traffic. This just takes time to remember how to drive more aggressively.

Why offset grind a Moldex crank when you can spec out a aftermarket crank to suit your needs?
hyper-eutetic pistons are not ideal for boosted builds , use forged pistons for boosted or poweradder builds..
The only real reason to change pistons is because the stock rods are junk.

Don't you have anything better to do?
If you want results get a group buy with 50 buyers paid in full
with all money placed in a escrow acct and my shop will release a total
turnkey longblock with ecu tuning.
