So, lets imagine that you have won the lottery and you need to build a two valve redblock, what is yours parts list?
This engine that i'm gonna "dreambuild" is for the street/strip use, so it had to be drivable on normal streets without problems and if you want, you can go to strip and broke 10 sec limit.
What i start this build is a Motordesign Sweden R-block with 96.30mm bore.
Then i put to it ACM:s 3000cc billet stroker kit for radical turbo use.
Then i send rotating assembly with front pulley and custom flexplate.
When short block is ready i hire somebody to make a "oil pan", then i put a dry sump oiling system to it.
For cylinder head, i choose evo 2-valve head with 52-39mm valves with 7mm stems. This kind of head flows incredible 300cfm!
Because it had to be street drivable i put a automatic gearbox to it with 4500rpm stall speed.
Then i can use a custom billet camshaft with following specs, duration at 0.050" 275/275 and 16mm lift, 114LSA.
Next thing will be chosing turbo to engine. Because it is a 3liter engine it can handle a little bigger turbos also. But i choose a twin scroll design turbo with ball bearings. Good choice can be something like BorgWarner S476SX-E (Comp. 76.00mm / Turbine 81.74mm), exhaust housing is a a/r 1.00 and twin-scroll, or dual-volute as they say in B/W.
It can produce 100lb/min at 3.0bar or 43.5psi, which is enough to 1000hp.
But i can drive it with a 2.5bar, then it goes with 76% efficiency and can produce 850hp.
Next thing that i buy is a big Ic with 4" core and size can be something about 300mm*500mm or 12", 20", 4". Intercooler piping is 3" all the way through.
Now i only need a intake and exhaust manifolds.
With exhaust manifolds i choose a Finnish made KKD-motorspots custom exhaust manifold. KKD-motorsport owns Europes fastest Supra.
Intake manifold is simple one, i put a Lensu power shops cast intake manifold to it, it is same casting as Kl-racings manifolds, but quality control is better, and i can buy it in Finland.
Then engines "hard parts" are in good shape.
With this combination engine pulls hard at 4500rpm to 8000rpm.
Engine runs of course with E85.
Engines ecu can be Haltech Elite 1500.
I can drive it full sequentally for fueling.
For spark i drive it sequentally and i use Coil Near Plug system with IGN1-A coils.
This kind of build can produce reliable 800hp, and if you want to go crazy it can handle 1200hp.
Even without forced induction 3liter redblock can produce easily 350hp and very broad torque curve.
What kind of two valve redblock you build if you had the money?

This should be good.
