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?

well if I wanted a high revving N/A i would buy a honda...Ive seen the ST185 that hits 10k rpm like its no ones business So I know it can be done...

The valve train will be completely replaced, my concerns are oil pressure, cavitation, fuel delivery and valve float...

Yeah i was figuring the ID 2000s and a larger fuel rail, and a big fuel pump or 2 inline pumps on a swirlpot... the FUELAB pump in my Gt4 is deafening, very very loud and 4 were brought to PY, 3 of em failed on Ethanol, my car was ready a year later so I am crossing fingers it wont die on me. its on LOW speed only which is around 60 psi.


I would use the Fueltech FT-400 EMS same as my car... very nice and cool factor touch screen...
