Long term living room project, Looking to build a 10k rpm 3sgte Options

[Neon90424]

Since i have pretty much completed my gt four engine wise. machined and head kit also installed. I feel like building a 10k rpm engine with a 3sgte. I was looking at 3sgte's and I have decided to go with the newer ST215 engine since I have found them cheap on Ebay for 1k, and have it shipped by boat to PY. Going to buy an engine mount and set it up in my living room.

I figure the side intake manifold is better flowing than the 3rd gen and COP system to be nicer for a high rpm flowing engine.

Im looking for advice and tips. My plan goes as follows.

Buy and bring the engine.

Major tear down with about 100 ziplock bags and catalog it.

Clean it completely. turn the pistons and conrods into some sort of table or ashtray or shot glasses.

Take the head apart. polish it. have it machined for .5mm over exhaust valves and 1mm over intake valves.

looking to go shimless bucket. TI retainers and BC valve springs.

machine the crank lightening it up as much as possible without unbalancing it and compromising its strength.

eagle rods and cp pistons. acl bearings.

maybe make a custom aluminum oil pan? I need advice on the oil pump and flow for this engine.

I will set up a nice Injector dynamics based fuel delivery system that can handle the injection speed for 10k rpm.

polish the intake manifold runners...


I need True and false advice. I read that the oil pump the st215 engine has is higher flowing and water pump as well.

the head has better flow and the manifold as well... The exhaust manifold and turbo is going to be sold.

This is going to be a 400-500 hp engine. the donor car is still not decided to me as I will complete the engine first and I will do this real slow say a year or 2 So i might pick up and ST185 and drop this in.

thoughts ideas advice? flame?

Revving to 10k is just great but you need to think

How am i going to make power up there? Hence EXTENSIVE head work is going to be needed, cams your looking at i'd say 304 degree duration, and a lot of lift. that will be the key to power if it was n/a but since its turbo you need to think what turbo is going to make power up that high as well? and no lag.

Also the key to getting to to rev will be weight/ balacing light weight rods pistons and cranks, also flywheel will have to be light as hell and balanced insanely well. also dry sump will be a must, got to remove any unwanted weight from the engine its self

i honestly don't see the point in high revving turbo cars but each there own
