hey guys,
I'm finally able to start the assembly on my engine. I've got a h22a4 sleeved and o-ringed by golden eagle,Scat Racing rods, J.E. Pistons 9 to 1, Ferrea Valvetrain,Cometic head gasket, ARP main rod and head bolts. The head is ported and polished and I had a 3 angle valve job done. My question is, Do you guys think I should upgrade the oil system, or is stock o.k.?If so what brand and where can I get it? I'm gonna be running 25 psi on my t66 so the horse power will be around 500whp with the 50 shot of NX nitrous. Please help me out here. You can see what i've got done at http://www.cardomain.com/id/holdem1981 for more info.thanks.

 

i was about to yell at you for running 25 psi of boost, but then i saw your vette and realized you prolly know what you are doing.

bump to the top, because you need to know. You might also want to check out the other performance forums too. they might know...right now you are limited only to the prelude drivers, lol.

nice vette btw

[edit] Also, i hope you are upgrading atleast the clutch, and also the tranny would be a good idea too.[/edit]

 

yeah tranny is a base model, quaife, and a prolight fly wheel, still undesided on a clutch. thanks for the help. The oil pump is the only stock part left in the engine, and I don't really want to go with a dry sump like Moroso.Plus the turbo will get in the way of the dry sump, because the engineers at Moroso put it where the AC pump was located. I need help finding a good replacement setup that replaces the OEM pump.I have looked all over the performance sites and can't find one.thanks

 

About the only 'aftermarkert' upgrade to the oiling system is the Prodrive oil gear. I think it is a billit gear instead of a sintered metal piece. Otherwise I have heard of people removing the balance shafts and turning the bearings 90 degrees in the journals to block the oil flow. Supposedly this offers more oil pressure to the main bearings. Also you can shim the Oil bypass spring for higher pressure. Otherwise I can recommend champhering the oil orifices and deburring all the passages/junctions.
