Hey guys I'm starting to really get into track racing - even though I've only been once haha. Anyway - I'm wanting to make my GA70 a fun, fast, and decent track car. I have no spoiler at all on the back. I have lowered the car and it sits on a slight rack from front to back. The front is...

Hey guys If some of you are unsure what TVIS is - here's a basic run-down Instead of 6 intake runners, there's 12 with butterflies on every second runner. These butterflies close at low RPM which intern increases the intake air/fuel's velocity giving more low down torque. The standard...

Hey guys I've uploaded a really awesome convert tool. Convert almost ANYTHING you can think of. Seriously amazing! http://supras.co.nz/temp/convert.zip

Not sure if this has been posted before: http://www.toyodiy.com/parts/

Hey all, Took my Supra round Pukekohe on the weekend. Its a bit of a power track, which was nice for the supra - but quick scary! Had an "interesting" day. My oil drain was leaking which I wrapped in heat wrap, turned into a smoke machine, almost catching fire. So after about 3 laps, I had...

First time racing since I've built my car. 13.63 @ 105.62mph The winning race, 7M vs 1G - awww yeah :) I generally span off the line (note tyre smoke in the first race!) or I'd bog HARD. And I was being slow and gentle with the changes. No flat shifting etc...

What would happen if your car was dyno'd in 3rd (being a manual it should be done in 4th)? Has anyone compared 3rd gear pulls to 4th and the power readings for each?

Hey all I'm in Londono till the 14th May. Who wants to come show me their car? :) :) I have no transport, other than public of course Email me: huntm@ddb.co.nz

Hey everyone: Take a look at this video. Ignore the text in the video and the miss etc - its an oldish video but the sound at the end of each pull is the same as now - is it compressor surge? Its NOT coming from the BOV - it's coming from the turbo. The BOV is opening - but it would...

Hey all, Dyno day went ok. Kept blowing intercooler pipes off. I really need to get rid of all the joiners I have and weld lips on the pipes. Boost controller isnt set up properly - (I have it set up as a bleed system rather than, well whatever the other way is where it applies pressure to...

Has anyone tried to used the rally mode of the anti lag option for the Stinger 4424 ECU? I can get drag mode anti lag to work but I cant get rally mode to work. My understanding is when I have it set to rally, I back off the throttle, the ECU changes the timing and the fueling so it...

Hey all I've got the diodes wired in proprely - the first 2 coils are fine but the 3rd is going nuts - and only on one side of that 3rd coil - i.e. number 2 cylinder is firing slower than the other cylinders, but number 5 cylinder is firing almost constantly - you can barely see it not...

Hey all I have a 1G-GTE with a 4424 Stinger. I have put this thread in the 7M-GTE section as I am using 7M injectors, ignitor and coils. I have a "very" bad miss from 2,300rpm right up till around 5,000 rpm when full boost is reached and the miss seems to go away a little. I say a little...

Using a Monza SSQ BOV. Running around 12-13psi in the video: http://www.youtube.com/watch?v=EFt05ck2iYg Any thoughts peeps? :1zhelp:

Didn’t hone the bores when putting new rings in, so they didn’t bed in properly. OOPS. Yes yes I know – stupid me. Anyway – pulled the engine apart – as it turns out number 5 middle ring was upside down also haha. Two ring landings on number 6 piston crumbled as I was taking the old rings off...

Hey, What would happen if the wastegate I have is too small? Boost creep? I have a fair bit of lag as it is due to large exhaust manifold runners and quite a chunky turbo. I'm only a 2 litre - so I wont need something as big as what you'd find on a 7M or 1J but the one I've got is off an Audi...

Do we (supramania) have a "team"? If not whose should I join? :)

Hey all, I'm posting in here because I sort of took over hottscennessey's "7M Stinger" thread. My appolgies hottscennessey, hope I didn't ruin your thread too much :icon_razz I've finally got my car going pretty well. Here's the details Stinger 4424 standalone ECU 1G-GTE core engine, DFL...

Hey all, Can the wideband sensor be hooked up directly to the stinger? Or does the sensor need to go through the wideband "brain" and then into the stinger? I'm using the W/B sensor that you get with a Zeitronix kit

Hey all, I am looking at mounting my 7M-GTE coils on the firewall lip like a lot of you have. My question is this, do you use a special brace under the coils? I would have thought the coils would be too heavy and would stress and bend the lip without a brace? I have a 1G-GTE engine, so I...
