[southwest2118]

any body know the oil pressure i should be getting at the TEE next to the filter on the 7AFE? around what?

i think it is around 53-60 psi on a cold start

[Batman722]

from the BGB the oil pressure is around 3.8 to 71 psi

whats BGB?

[playr158]

big giant book.....toyota's handbook on the celica

but yea normal running pressure as batman says is 71 (too high for a turbo )

i get 45 or so at startup/ under throttle. At rest and warmed up the oil pressure should be like 5

[Dr_Tweak]

45 is right around where you want it when warmed up and under throttle, generally.

71 is more like when you just started it and it's COLD. Even then... that's pretty high and not normally seen.

at start up i get like 50 and under throttle its like 60 at rest its like 3... dose that sound ok??

Yes

-3an piping or Restrictor ??

[southwest2118]

??? its for a rebuilt t3 .42/.48 A/R??

[Dr_Tweak]

They say you're supposed to use a restrictor if the pressure goes over 50 under load...so then yes.

I've heard of people using them and blowing their turbos, and I've heard of people using them and having great results.

I've heard of people not using them and blowing their turbos, and I've heard of people not using them and having great results.

Choose your poison.

come on doc what do you do?

[Dr_Tweak]

It's on a case by case basis.

I buy the restrictor, but don't use it, and then I measure the oil pressure right at the turbo. If it's within reason then I go without it and if the turbo doesn't smoke, then I don't use it. If it smokes, then I install it. Either way I give it to the customer to keep so that if the turbo starts to leak oil down the road, they can put it in (if the oil pressure is the problem).

at WOT I'm at 60 psi....so i should try just running any size to the turbo if it starts to give me problem buy restrictor.?

Well, don't run anything bigger than -3 AN or 1/8" which is what it's equal to.

other then the internet where can i get those sizes? and steel braided? i have female 1/8" npt on the Tee from the block and the turbo.

hey doc you think i can run 5 psi with no fuel mods?

from the compressor housing to the Wastegate, should there be a boost controller? Like Nik?

Typically I order all my AN stuff online, I can't get it anywhere locally. However, since you have a 1/8" npt on both the tee from the block and the turbo, you can just run a 1/8" high pressure line (like a hydralic line, you can get these at pretty much any parts store) with clamps. Of course you'll need a 1/8" barbed fitting for the line to fit over. Then you don't have to mess with any of the stainless AN stuff (although that looks a lot nicer).

No.

If you know what the wastegate is set to then you don't need it, no. For that matter, you cannot run anything LESS than what the wastegate is set to, a boost controller will only allow you to run MORE boost. (For example, if the wastegate is set to 7 psi, you can set the boost controller to run 8 or 9 psi, but you cannot set it to run 5 or 6 psi. The wastegate setting is the MINIMUM.)

how do i know what the wastegate is set to?.........


you think i can get away with a fmu and a bigger pump?
