I don't understand your first question. I would guess you need bypass as that is how the BOV will be functioning when you recirculate. One thing is certain, the SSQV will be a lot quieter when you recirc.

That's the lower cover I was talking about. It can be especially hard to fit if the tranny and engine are already snug together. IIRC it's got a little tab that it needs to slide around the top cover. And it only goes in one way. Unless you physically bent it I doubt it would ever get...

I just bought a VPC harness from HKS about 2 months ago. Came direct from HKS. Rczop2 yes, however I'm not sure how you would wire it up. One thing I do know is you would need this order VPC to Rebic to ECU. Really the VPC should be universal with any other piggyback computer, you just...

Never taken it to a strip, but before my VPC, DDP and tire size upgrade I raced and beat a SRT4 that said he runs consistent 13.0's. So my guess is I'm in the 12's somewhere.

Yes there are two plates like that. One has a hole for the starter and basically covers the top. The other covers the bottom portion.

Why are you trying this aftermarket O2 instead of the stock one?

Last time I talked to Toyota they said they only made standard size and 20 over. Personally I wouldn't feel safe going over 40 over.

So I was out of town for work a few months back and I was driving home for the weekend. Well I'm on the interstate out in the middle of nowhere, I'm driving along around 70mph when a crotch rocket comes flying up behind me. I'm bored b/c I've been driving for the past 2.5 hours and I'm only...

Those look exactly like the Painless wiring connector I used on my CPS. No special tools were required. Got them from Summit or Jegs pretty cheap. Only thing I didn't like about them was that they had no directions included. The harnesses aren't 100% intuitive as to how to put them together...

It's possible the MDC O2 sensor can't be driven by the stock heater. Try plugging in only the signal wire for the MDC sensor and leaving the heater circuit disconnected. Verify the MDC is putting out a good 0-1v signal and see if the ECU code goes away. I'm not sure about 89+, but I know on...

Toyota makes standard and 20 over pistons (the ones you are referring to). I've also seen some aftermarket piston companies making as large as 40 over. Personally I wouldn't sleave the block.

Yes this could cause basically a massive exhaust pressure leak which might result in no boost. Most CT-26's I've seen do not have that crack, it appears to be related to excessive boost/excessive time boosting. Anything that will overheat the turbo to where it's glowing red will tend to crack...

Thanks guys. SM sure beats any of those other supra forums. Rajunz if I've got any free time I'd like to meet up. Gulfport is only about 2.5 hours from my house. We might even be able to make a little supra meet out of it. We've had a meet in Gulfport before, it's not too far for most...

You need to connect the EVC vacuum line to the port on the back of the intake plenum. That way you make sure you aren't behind any VSV's or interferring with the FPR. If you aren't throwing an O2 code, then I would guess the problem to be fouled plugs, weak ignition or small boost leak.

Stock gauge is both slow and inaccurate. I know you will lose some boost at higher altitudes however I don't know the formula.

Arthuricus, nice to see you posting. How's your car running?

The W58 will work until around the 400rwhp range. The ECU and most of the electronics are completely different.

Typically when the master and slave go out fluid leaks on the floor and under the tranny. You'll also experience the clutch pedal feeling mushy and sticking to the floor. It usually causes the opposite of slippage, it gets harder to shift gears b/c the slave cylinder isn't pushing the pressure...

Sounds like it could be either a small boost leak or a problematic wastegate. If you have access to a compressor with a regulator put 12psi on the wastegate actuator and see if it holds it.
