89 turbo supra 5 speed dies in mid shift????

[jtown125]

I just bought a new bov and recirc kit...

ill let ya know how it goes...

it will probably be the week after next before anything gets here anyway....

[cre]

Way to cave to the peer pressure... (yes, I know I'm a dick)

Did you look for a recirc kit for your HKS? They're out there.

Are you going to just run recirc or a BOV/BPV combo?

In the end you should still consider saving up for a good fuel controller and some tuning.. you'll be able to run whatever BOV/BPV you like and you should be able to wring a bit more power out of the engine.

First off...I sure as hell aint made out of money and I agree that a 300 dollar tuner would be pretty nice.

The kit that I ordered is an hks kit, but the offbrand bov i bought is exactly the same so i will try em both out and see what works better.
The bov isn't that hard to take apart to put the 1" hose clip on.

Im not going to put a bpv on cause i think that will just be in the way...its already tight as it is...

OH, btw I had probably another stupid question im sure that you could answer...

the vacuum places where the OEM bov circulates....if i was to put a vacuum line there...could that possibly help? Just curious since i have a week to mess around with it.

And one more question...Does it hurt that my exhaust has the wastegate runner and its cut off?

and thanks for admitting your dickishness...
ill admit my stubborn bastardness...lol

I've seen a very high power MKIV with 3 PBV's. When you've got a lot of air to dump, sometimes one just isn't enough.

I don't quite follow.... The You are, I assume, referring to the intake's inlet for the BPV's exhaust or discharge? If so, with a BOV you just want it plugged. When you install the BPV kit the discharge will go there like it was in the stock setup. The vacuum system goes positive when you start boosting, running a hose there will just cause a big boost leak.

Comes with the territory. Some people bring it out in e more than others. No, I'm not referring to you; Someone else has been ticking me off.

I didn't know what that outlet did...
both outlets are plugged for original bov.
i was just curious...

and what fuel controller would you recommend?

A BPV/BOV has an inlet and an outlet. The inlet is on the boosted side of the intake, between the turbo and the throttle body. The Outlet side is on the ambient/vacuum side of the intake, before the turbo (and after the air flow meter in certain setups like this one). The poppet/valve is held closed by a spring and depending on the type the spring is assisted by the boost pressure. When you let off the throttle the intake plenum (the portion AFTER the throttle body) pressure goes negative and the manifold reference (the small vacuum line) goes negative sucking the poppet/valve open against the pressure of the spring. The strength of the spring dictates how much vacuum is required to open and keep the valve open. Excess pressure between the turbo and the throttle body is now discharged back to the intake before the turbo. This prevents new air from entering the system and the ECU doesn't add any more extra fuel... you don't run lean though because the ECU has already measured and allocated fuel for the air which has just had its trip extended. If you just dump the air out, the ECU still thinks it's in the system and it still send fuel for it.

I follow...
reading always helps...

the hks vpc...is this a good tuner?
and how hard are they usually to install...

maybe i will spend my tax money on one...
taken i get the bov thing fixed when the parts get here...

Again, I have no idea what you mean.... doesn't sound good though. If you want to control the wastegate then build a ball valve controller for $30. Don't cut anything, don't add any washers and don't weld anything...

It depends on your final goals, how much you're willing to budget for and if you are willing to wait until you can get something really beefy or if you just want something for now. The Apex'i SAFC-II is an older unit but very reliable and very popular; Its successor is the Neo, an equally popular unit and even more flexible and user friendly. Beyond that you're looking at a MAFT Pro setup or a full stand alone EMS.
