Hell, that's nothing.. We've seen far worse:

Good name for them... In most older systems it's based upon simple mileage. There are a few newer systems (BMW's Condition Based Service System and GM's Oil Life System as examples) that factor in driving conditions. The BMW system also performs an "oil quality test" via the electrical...

Good name for them... In most older systems it's based upon simple mileage. There area few newer systems (BMW's Condition Based Service System and GM's Oil Life System as examples) that factor in driving conditions. However they are all "guesses". None of these cars are running around with a...

It's simple math. All you really care about is the final compression ratio... A simple (slightly inaccurate) formula for final compression ratio (FCR) at sea level is (Boost / 14.7) + 1) x CR For example, if you can run 10 psi on 8.5:1 pistons safely on your fuel, your final compression ratio...

Don't Goggle Dave!

DO NOT Google image search for felching. You will regret it.

Shit, this isn't the mod forum is it...

Eh, we've devoted more bandwidth to worse. Need I remind you of Hommers dashboard?

There are quite a few people around here that have been messing with these cars for longer that two years who I would rate at a knowledge level of "doesn't know their own ass from a hole in the wall". And no, I'm not naming names - do a little reading - they stick out like a sore thumb...

Exhaust cams on both engines are identical. Turbo cams have more lift and about 10 degrees more duration (opens earlier) on the intake. Running a GE intake cam in a GTE produces a slight increase in low end torque and loses horsepower up top. Here are the actual profiles as measured (ignore...

Differences: Different pistons. (8.4:1-turbo vs. 9.2:1 for the N/A) Different intake cam (Turbo cam has .0074 more lift) No oil squirters (oil galley not drilled & tapped for them) Turbo oiling system missing. Turbo coolant system missing. Turbo has 2 knock sensors (NA has one, but...

Have you considered the stock compression ratio on a 7M-GTE is 8.4:1 and the 7M-GE is 9.2:1? In most NA-T applications I've done, we've always used a 3mm MHG to drop the compression ratio down. Also, the cam profile on the GE motor isn't really the best one for turbo use. Why not do a...

Here's what I did: Drained off 3 gallons of gas from the tank, then added a gallon of methanol and 2 gallons of xylene (Not Zylene, which is apparently some quack weight loss remedy). Drove the car very gently, mostly around town (no highway miles) until I was down to 1/2 a tank. It went pretty...

Tell him walk.. No. Run away...

There's a whole subforum dedicated to the topic of oil, etc: http://www.supramania.com/forums/forumdisplay.php?108-Motor-Oil-Lubricants-amp-Filtration Everything you need to know about oil for your Supra is in that forum.

Here's something I posted a long time ago (see bolded text below) when talking about BHG's on the 7M that may apply here: The absolute most common failure mode of the 7M head gasket is to get compression into the water jacket. When they fail like this they tend to run fine and push coolant out...

Not to mention the vendor who asked the original question has been out of business for a few years....

PM sent.

Funny, thier contact email on the About Us page is the same email you registered your account with... Nice try spamboy, you're out of here.

Folks - that's a decent apology, so end it here and and drop the infighting. Let's get this thread back on track.
