Never heard of that issue...

Yes, I sanded them down with a dremel. It's the edges of the valve reliefs that we're talking about. Probe made the reliefs oversize in case the customer went with bigger valves. Peoblem is, it leaves a sharp little ridge next to the edge of the piston. Sharp edges= hotspots=pre-ignition=...

Well, like I said- I don't know why people were throwing around lower numbers for the Probes. If stock pistons can handle 400+, I don't see why forged probes couldn't handle some much bigger numbers.

I kinda think that a stock na MkIII will always beat a stock pre-84 MkII, and you're turbo, so... And, you have $3500 in automatic transmission A340 upgrades??? How is that even possible? You know what a $500 A340 upgrade is? An R154 swap. ;)

He kept up because you hit fuel cut 3 or 4 times. That's a HUGE disadvantage. Sounds like a big turbo and no fuel/ air mods is what's limiting you.

What's the fine for getting caught shimmying up a camera pole with a jar of vaseline?

well? I wanna see these pictures.

You're putting Probes in a 700hp buildup? I have Probes, but I wouldn't use them for that hp target. I vaguely remember the consensus during the group buy was that these were intended for the sub-500hp range., but I don't really know why people were arriving at that number. I'm going with...

I'm guessing that rolling the fenders could help a bit for most of your driving.

Nah- judging by the offsets, those are for old-school rwd- RX-7's, 510's, Z-cars, AE-86's, AW11's... Anything from 70's - early 80's.

I would try lowering Fp by maybe 3 or 4 psi, and just see if there's a benefit. My pressure is set ~38psi.

ps- I just noticed that you're using a bigger turbo. I'm on a stock CT(for now).

I think i've mentioned to you before that I have almost the exact same setup as you, right down to blow-thru mode and 560's. I would simply check for boost leaks, as that it the most common cause of FC. I have not pushed my boost past 16psi, but I have yet to hit FC at that level.

I think I read just recently that ferrea makes keepers// locks, and they claim you should use them specifically with their valves.

Do a leak down test. It might isolate the problem to a particular cylinder.

Got it. Out of curiosity, I'll email them about it.

Hey- you were totally right! http://www.horsepowerfreaks.com/performanceparts/Toyota/Supra_MK3/Body/Front_Lip_Spoilers I don't really care so much about the ducting, I just want a new front lip, and everything from shineauto is too low for my taste. Thanks- looks like I'm saving my money for...

Am I correct in thinking that the JDM 89-92 lip came with small brake ducts? And if so, Does anyone know what direction I should look to for sourcing one? PS-! Does anyone have a pic of one? thanks.

Yeah- I think Driftmotion sells it for $36.

I assume we re all talking about the spherical bearing at the lower rearmost point on the hub. Can anyone tell me the secret to removing this bearing, preferably on the car? I tried using a 2 arm puller, but couldn't keep the puller stabilized. Do I need to remove the entire hub, and throw it on...
