my mistake i just assumed it was a 1Jz since youre in japan, im not familiar with the G series engines, how does it compare to 7Ms and 1JZs?

ive heard good things about the g series, high reving and fun to drive.

jap sup: most people on here have a 7m so we may not be able to help you to much, but we will certainly try

The 1G was fairly uncommon... an underdog of the MKIII world. They're definitely a rev happy engine with decent (but not phenominal) potential with some upgrading. I don't think that engine even made it to Europe. There has been a lot of speculation about how much power they're capable of, but the few people who've tried building it here in North America have all bailed on it. Parts aren't easy to source, they're expensive to ship in and the 1JZ and 2JZ offer greater gains from the same amount of work.

While a BHG is not big concern on the 1JZ, 2JZ and 1G the potential always exists.

Oil leaks on the top (upper half) of the engine are most likely coming from loose valve covers, dried and shrunken seals (such as the one on the CPS or dist. or cam/valve cover seals), or cracked hoses.

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.
