2 new problems....

Japanese supra tt · 06-26-2007, 01:52 AM

yeah, the 1G has come kick to it, and it definatly gets the job done.
lets put it this way, the car can clutch kick in 3rd.
the twin turbos have some lag of course but its not anything thats too bad.
alrighty, when i go to the lift again, looks like im draining my radiator, installing foglights & wiring, checking for cracked/dried hoses, and checking torq on valve cover.

oh yeah, and yeah i relize most ppl have 7Ms or 1j's. its all good, you guys help out more than enough haha.

Wow, I just noticed that the 1G uses a VAF (Vane Air Flow) meter.... like the 7M-GE N/As. What a horrible restriction to put on a turbo car. I wonder how much of an increase that engine would see from just converting to a MAP setup... even without tuning there would probably be a decent gain. I'm stunned that Toyota would use that in that setup.

yeah ive noticed that too. need to get all my shit running like it should...or close to it before i go and start swapping parts for upgrades...
(oil leak, headlight relay, plug wires, foglights, all need to be installed/replaced)

im assuming you guys would reccomend MSD 8.5mm plug wires?
seems like the best out there.

opinions?

ohh yeah, ALSO IMPORTANT: my oil pressure is sky high, it reads around 6 to 8 sometimes, on the stock gauge if im just cruizing at about 40 KPH and 2k rpms...
wierd.

Yes MSD wires are the best you can buy for a MK3.

Look closer and you will see that the 1G shares another part with non-turbo 7M's, that would be a distributor. No DIS ignition system there. That hinders performace likewise, no wonder the engine was only rated at 210hp with twin turbos

So I would guess that you would use MSD wires for a non-turbo MK3. Because "turbo" 7M wires will be too short because the coils sit directly on top of the spark plugs and you need them to reach over to the distributor.

6 to 8 what? Bar? If its bar, then holy shit you have problems there. Thats like over 80psi. I don't know much about 1G's, but I know enough to know your oil pressure is too high.

*cough* Taylor */cough*

The down side is you have to build them yourself.

Yeah, 6 to 8 what? Kg/cm^2?

Japanese supra tt · 06-27-2007, 02:19 AM

6-8 kg/cm^2

thats what it says on the gauge.

sometimes it will be around 4 like its suppose to, its wierd.

cre · 06-27-2007, 02:38 AM

Wow, that's from 85 - 114psi. Bar, by the way, is damned close to the same as Kg/cm^2: 8bar = 116psi 8Kg/cm^2 = 114psi.

Keep in mind though that oil pressure is not static, some increase per higher engine speeds is normal (if it wasn't going up I'd be worried).

Any way, that's a lot higher than I would expect to see from a Toyota of that vintage. What weight oil are you running? Did the previous owner do any of their own work? They may have modified the oil pump's relief valving. Look for the pressure specs per RPM for that engine, it may be fine... I really don't know.
