One of the most extreme custom engines I have seen.

What do you need if you get bored and want to shoot for 2000whp with a 2.0L engine?


Cast Garrett compressor wheels (right) tend to come apart above 50 psi. CNC billet aluminum wheels (middle) are stronger, but why not be different and use your own CNC billet titanium (left) compressor?




You'll need a turbo big enough for the job, which in this case is a 108mm twinscroll T4 turbo, with custom quad ball bearing CHRA and 100psi capability.








To get enough airflow at 12,000rpm(!) to get the job done, you'll need a skillfully ported head, complete with titanium valves and copper-beryllium valve seats:








And you're going to need a set of camshafts to handle the rpm and withstand tremendous ramp pressures, so why not a set of hollow titanium billets with DLC at only 234 grams each?

And since there is no aftermarket rod up to the task, just ask for a set of billet mmcs-titanium connecting rods at 286g each. Rod/Stroke ratio is 2.07:






For pistons, a set of custom beryllium pistons with DLC fits the bill, and since methanol is the fuel, 13:1 SCR is fine:







A strong piston pin is needed as well:






Toss in a custom titanium billet crank:





A set of 9000cc/min injectors:




And since a factory 4G63 block probably wouldn't hold up, just CNC machine your own from billet aluminum:






No head gasket is used:




And to put all that power to the gearbox, one needs a suitable multiplate clutch:




Yes, it is smaller than a cam gear:






An example of very efficient turbo manifold design from one of their recent projects:
