Dude, if my Supra looked like yours and was all stock, I wouldn't even worry about it. I don't know where one has to live to have that draw so much attention. Look at some of the build threads here to see some truly impressive examples of the MKIII supra that have tens of thousands of dollars...

^ That's pretty much where I am with all of this. Unmetered air isn't an issue for me since I'm now on standalone and pressure readings are taken from behind the tb butterfly. Thinking of adding a check valve to the accordian hose to provide maximum vacuum on the valve covers at idle, although...

Like I said, I run a ffim. Not using stock tb or turbo or boost levels for that matter. So pretty sure a check valve is needed run from the ffim to the catchcan. IJ's setup uses one there.

You must have misunderstood. I was saying that it would make sense to add a check valve to the accordian hose IN ADDITION to the check valve to the throttlebody/intake manifold. Your latest diagram would have you pressurizing the catchcan under boost, or at the very least, have a massive boost...

That's basically how I ran mine, except I have a ffim. I still don't understand how the TB isn't just pulling air from the accordian hose when under vacuum rather than the valve covers. You'd think a one-way check valve should be used on the accordian pipe as well to prevent this. I was told not...

A+ for jamming a 2jz upper timing cover on there. :biglaugh:

Finally got my car into the garage. Got the wideband working again (loose connection) and it was all over the place. Smoked the intake manifold through the brake booster nipple and smoke started pouring out from the back of the manifold towards the bottom. Not sure yet if it's from a bad weld or...

I remember seeing this back in the day. Still looks like something Doc Brown concocted. Besides the "First Encounters" light show, the font used on everything just kills me.

^ I heard great things about the ProEfi, but since it is not plug and play, my shop wanted over $800 just to do the wiring. I went pnp AEM instead. About as pnp as you're going to get right now. Spend $65 on a dh61 ignitor and splice it's ten wires into your factory ignitor harness and you'll be...

Your turbo sounds fine to me. Minor side to side play is the norm for a journal bearing turbo. Upgrading to a larger wheel is always fun, but if cash is tight you can spread your funds elsewhere and just shim the wastegate of your current turbo to gain some free and easy ponies.

Does the turbo smoke? Have you checked it for shaft play both side to side and back and forth and seen if it was in spec? Is the wheel damaged? Very hard to tell from the pics. Answer these questions and you'll know if you need a new turbo.

Ok, so I finally got time to drive the car again. Battery was dead so had to charge it up. Fired up the engine and it idled perfectly at 1700rpm and dropped to 900rpm when warm. Looked at my A/F meter and it was steady at 14.7 afr. Started driving her around and noticed that the afr wasn't...

Like I said earlier, I only drove the car for a few minutes. With all the little issues I don't even feel like drivng it until they're fixed. Especially my turbo and radiator fans (controller fried so I'm going to wire them into the EMS). And I'm so busy at work and opening a new store tomorrow...

Really? Maybe it was 10.5 AF then. Whatever it was, it idled at the same AF as under boost. I need to get the time to troubleshoot the thing. I highly doubt I'm running lean. What should the target afr be?

Only drove the car for a few minutes, then had it towed back home. All sorts of little issues that I need to iron out. The most important being a smoking turbo. When I went to pick up the car, I noticed the intake pipe was off and there was oil mist all over the inducer. ISP said the turbo...

^ Did you ever get it running? I couldn't get the 2jz TPS to work properly so I had to bite the bullet and go AEM EMS.

The one I use appears to have had just the upper plenum cut off and welded in place off the 7M's so fitment is perfrct and everything lines up. A 1½" bar of aluminun was welded along the right side to fill the gap between the plenum and runners. Still the best looking conversion I've seen. I...

I just started running a Turbonetics HiFi 62-1 journal bearing bolt-on turbo which starts smoking as soon as my oil pressure starts to peak at the higher rpm's. But doesn't at lower rpm's. SupraSport sent me a pre-fabbed line kit. The feed line has around a -6AN line with 4-AN fittings crimped...

Cool. Thanks for that Grim. It's a shame that I can't just slap in some 1000cc injectors and rev my motor higher. However, with the turbo already maxed-out, it's not worth the expense or re-dynoing for maybe 15 more horses. God I sure hope this car is a blast to drive as it sits. I can't dump...

Yeah Grim. The wastegate opening is ported as large as it can go. So much so that I had to have the flapper adjusted since it was getting hung-up on the edge of the ported opening. I can't understand how the turbo won't produce more than 21psi and how I can only get 415hp out of 550cc injectors...
