supra90turbo - Shameless! LOL :biglaugh: Tell me about them...how do they compare?

Need opinions on plug wires...MSD, NGK, etc Advantages...disadvantages. Thanks! JW

I got something kinda the same at high boost (16+ psi). I'm running a Lex/550 set up with a Aeromotive FPR. I installed a Walbro FP and it fixed the problem w/ ~30 psi on the FRP (vac line connected). I still hit fuel cut at +18 psi boost :icon_conf

Use new bearings...rod & crank. Cheap insurance!

This one is nice...dual core and cheaper than the Fluidyne. http://www.coolradiator.com/HPAToyotaSupraTurbo3.htm

PM me if ya want to add a little under hood :bling: I do ceramic chroming (2000 deg commerical grade) :naughty:

I don't have the Greddy, but I did pretty extensive mods to a stock '89 bumper (see pic). I have a TruCool tranny cooler w/ Spal fan under the drivers side and use the pass side as a cold air intake...didn't want the stock fog lights to block the airflow. So, I used Oplilux (Hella) after...

Mine idles at 15.5-16.5. 30 psi on the FPR with vac attached (Lex/550's) No issues...smooth idle at 650 rpm warm.

You need the '90-91, 2.0L Turbo w/ powersteering. This MR2 has electro/hydraulic powersteering, hence the need for a 100 Amp Alt.

OMG...I NEED that :bigthumb: Nice!

The VSV that controls the FPR is part of the "Fuel Pressure Control System"...it has a harness connection to the ECU labeled VSV2. http://www.cygnusx1.net/supra/library/TSRM/fi/FI_116.html To be honest...I'm not real sure of the function, but it's not part of the EGR system. That might be...

Follow-up: This discussion got me thinking, so I looked it up in the TSRM here: http://www.cygnusx1.net/supra/library/TSRM/fi/FI_073.html The fuel pressure with the vac hose disconnected should be 33-40 psi for the GTE motor and 23-30 psi with the vac hose connected to the VSV. This is...

That would be it! :drink1:

Did that too. Took the shield off to ceramic coat it and while it was off, still got the buzz :dunno: Drivin me nuts trying to find it!

Yeah...bugs the crap out of me too. Thought it might be the seals and/or the support tabs on the hatch. Replaced both and it's still there. Can't find the buzz...it only happens at certain times. I do get a rumbling noised from the center bearing. Got a 3.9 LSD with a TRD casing I need to...

I was having a problem approaching 18 psi boost (I hit fuel cut at ~ 20 psi); the motor would "hesitate" kinda like a mini fuel cut, but only for a split second. Also had the following readings at 18 psi: AFR ~ 13.5 Idle was 14.5, normal cruise 14.5 EGT 750 deg C (~ 1380 deg F) at boost...

Yeah! I get that buzz too...only at certain rpm, mostly in the 50-60 mph range on the highway. Kinda sounds like a resonance based on the exhaust note. You got a Blitz NUR Cat-back?

Hey thanks! I thought it was something that sounded like "Rubic" LOL Yeah, the guys car I saw it on was veerrry old school...had his '89 since it was new. He's a master mechanic; loves to adjust and fiddle with that stuff. Knows what he's talking about though...he's the only guy I'll let...

If it's a clicking sound, you might be hearing your new injectors :naughty: If you're getting normal oil pressure like in the past, it's probably not a problem.

Aggghhh...wouldn't it be nice to be able to go to the parts store and buy an alternator that WORKED. You spend the time fixing your car and install a "NEW" part that doesn't friggin work...then you get to re-do it all over again. Well...done venting...thanks for the help guys!
