SirCharlesworth Posted June 30, 2004 Share Posted June 30, 2004 So i'm guessing its the same trouble as the fd rx's have (my dads got one of these ) you loose the pre and main cats and the wastegate isn't big enough to vent off the larger amounts of exhaust gas. Therefore causing boost creep. I presume ported wastegate is a little expensive for the situation and to be honest, although i know the twin sequential on an rx like the back of my hand, i have absolutely no idea how it works on a supra, would like to find a diagram of the system but i can't. Incedently, some of the rx guys fit a "pop-off valve" to their cars, its like a bov but preset to a pressure to prevent overboost or damage from boost creep.

Suprash Posted June 30, 2004 Share Posted June 30, 2004 There are diags somewhere of the turbo layout, some very good ones, Im sure someone will post one, either that or PM Pete Sharp, he's always good for technical info and links...... Link to comment Share on other sites More sharing options...
secondjump Posted June 30, 2004 Author Share Posted June 30, 2004 Well i've got tyres being put on tomorrow at £158 each for 235/40 18's (rang everywhere, all were cheaper but none could sort me for tomorrow:mad: ). Hopefully the guy is going to have a go at fitting the restrictor ring at the same time. After that a friend working in a local garage is checking the tracking and alignment. ..........I think I want my corrado back:looney: Link to comment Share on other sites More sharing options...
dangerous brain Posted June 30, 2004 Share Posted June 30, 2004 Laser track dood thats what you want. Don't go paying wedges for tyres and then trash em for the sake of a few quid on a laser track. Unless of course local garage guy has the laser track jobber:p If he starts with a mirror setup run like fook!!! Link to comment Share on other sites More sharing options...

Only tends to affect the j-spec supra as the uk-spec has a larger waste gate as standard. Check this link out for a diagram of the turbo system.

Tyres have to be changed now to make her safe to drive and then i can take the car down to cousin-Jerimia, who's pretty nifty with a ball of string and plastic 12" ruler.

Mitcheldever uses laser, but they also have mirrors, the mirrors are bolted onto the wheels, and the laser bounces off of them. Should we be running from these setups ?????

Should we be running from these setups ????? Ashley, my problem stems from having a car that is very low therefore serious compromises are involved. I can feel CW shaking his head at some of the low set-ups some of us run. Unfortunately, I bought it this way not knowing any better. I guess its a case of change tyres more frequently or spend a handsome wedge on a more suitable suspension set-up. To be honest I reckon laser alignment wouldn't solve all my problems.
