20g mits what is minimum and maximum oil presure guideline

[AL92]

I need to know if anyone knows mits specs for the 20g .What is the minimum and maximum oil pressure?

I know I asked this awhile ago and got some replys but doesn't mits have actual min and max pressures for this turbo? I am not using them on a dsm.They are going on 408 cubic inch 99 trans am in an aps twin turbo kit. There have been some problems with the kits and so far haven't heard anything from aps.
So was trying to get actual mits specs if they have any.

Forced performance would know for sure but, most 4g63's run between 15-50 psi at the cylinder head through the rpm range, and the 20g survives in that range. I doubt the turbo failure's are oil pressure related, the kit's seem poorly engineered with not a lot of thought put into them. Are the turbo's actual mitsubishi turbo's or are they chinese knock offs?

If you haven't already purchased the aps kit, I would go another route. Something with larger ball bearing turbo's, or a big single with a huge T4 hotside. Twin 20g's just seems like a disaster waiting to happen, with all of the backpressure from the small T3 housings and the horrible O2 housings supplied with the kit.

Hmm ,well we have at least one guy on our f body forum that runs the aps twins on his 402. He is at only 12psi.Those too small turbos with their inefficient housings are giving him high 9s at near 140mph in a 4200 pound car. 720rwhp on an auto which is like 900 engine hp!! He has no issues with his. I took a poll and found about 5 out of 10 with no problems. But of the other 5 two actually had aps systems and the other three didn't so think they were just jerking around.

The gtos run the same setup ,the c5 runs the same setup the g8 runs the same setup.identical tweaked td06 20gs. Not hearing of really any problems from those forums .I have been asking.

Aso for bad quality not sure agree with that. The intercooler is awesome piece. the hot and cold side piping is excellent. There is problem with the air intake tubes on the f body kit. supposedly aps has a fix for it or will have to figure something out.They suck shut at higher boost a bit over 12 it looks like. There is some problem with sway bar interference.
Minor problem there mostly aftermarket big fat sway bars.
There might be some big problems with the turbos if they are using chinese crap knockoffs but at this time don't think they are. As said there are many gto ,f body and c5 kits with no problems making big power and running great times. Mabye they had a bad batch and didn't balance them right..maybe some of the problems are due to the intake tubes sucking shut. And lots of times oil coming thru is do to improper crankcase pressure or way high oil pressure. Some of these guys are running very high pressure pumps.And some didn't likely do the pcv mod recommended.

As for another system..well lost 2000 to a small company that went under last year.
And most setups force you to give up your airconditioning,have big overheating problems,,crappy ground clearance or other issues.

So will keep the aps but if necessay will send out the 20gs to have them tweaked /fixed if necessary.

Guess find out how my aps system works shortly . They have upgrade out with bigger turbos and this other shop is already modding /tweaking their base turbos.

I wonder how you can tell if the turbos are in fact knock offs or actual mits.
