uestlove Posted June 21, 2008 Share Posted June 21, 2008 Hey guys, Doing some research and always reverts back to this site, so might aswell join! I have a 96 Series 2 TT RZ. This is my 3rd Supra, first I started off with an NA about 6 years ago, then I had a 97 TT RZ and now this one. So far, i have Tein SS, full exhaust, de-cat & TRD Cat back, Defi Boost Gauge, Wed Sports rims. I have a boost spiking issue tho, peaks at 1.8 bar!

bluecoup Posted June 21, 2008 Share Posted June 21, 2008 very nice if you got decat have you got a ring limiting boost ? Quote Link to comment Share on other sites More sharing options...
uestlove Posted June 21, 2008 Author Share Posted June 21, 2008 Nope, i have done research here and notice you guys mention that, but i have no idea what that is Also it was spiking with even just a cat back, with the stock front pipe and 2 cats, to 1.6 bar!! Thanks btw! Quote Link to comment Share on other sites More sharing options...

R Black Posted June 21, 2008 Share Posted June 21, 2008 A RR is just a ring that sits between both decats or cats in yr place, that limits the boost, by the diametre of the hole, yes it is very basic, but it works, you sure your cats were'nt hollow?

Supra-Brett Posted June 21, 2008 Share Posted June 21, 2008 Welcome fella this site certainly does have some knowledgable members. Nice place, Oz went once to mission beach in Queensland. Absolutley beautiful place, would love to go back again one day. One of the things that made it so great and interesting (the wildlife) also made it damn scary for a brit though. Most we have to deal with is foxes and a few hedgehogs, but with crocs, jellyfish, spiders, snakes etc etc i felt like i was constantly checking everything for danger. Fantastic place though, and great empty roads to drive on too !!! Quote Link to comment Share on other sites More sharing options...
Tom Posted June 21, 2008 Share Posted June 21, 2008 Welcome does the boost spike then drop down to safe level or does it hold over 1.6bar too? Quote Link to comment Share on other sites More sharing options...
Tom Posted June 21, 2008 Share Posted June 21, 2008 also if you were to floor it from say 5000rpm on, will it still spike then or does it just spike on the changeover between turbo's? from lower revs? if so its sounds very similar to a problem I had, I was peaking at 1.5bar with both cats in but only when putting my foot down from low revs, but if I floored it when the 2nd turbo was in rev range it never spiked.

uestlove Posted November 18, 2008 Author Share Posted November 18, 2008 Hi guys, we found out that the owner in Japan tampered with the wastegates hence the crazy spike, fixed it, but it still spiked. Got an HKS EVC 6, didnt help, then i put a power FC in, got it tune today and made 280rwkw because its still spiking to 20psi.... Now its maxing the stock 440 injectors out, making it run lean. Is there a link where i can get the ring? Also my mods are: Full 3" exhaust, Dump Pipe, Metal High Flow Cat, Trust Intercooler, Trust Cat Back. Thanks!

benkei Posted November 18, 2008 Share Posted November 18, 2008 My mate has boost creep on his MR2 Turbo. That peaks and holds at 1.8 bar too! The cause is the XS-Power exhaust manifold. Simple enough to fix, but he likes it boosting like crazy! Can't see the engine taking if for much longer though.. Nice looking Supe BTW!

uestlove Posted November 18, 2008 Author Share Posted November 18, 2008 Thanks. Yea, problem is, car runs lean, AFR at around 12.8, not healthy, especially as I want to track teh car. I think the only solution is the restrictor ring???? Will i loose much power with one on? Anyone have a picture of it? Fizzle, Im in Sydney, bout 5 mins from the airport. BTW lads, ive been a member for a few months now and have done a bit more work to my car hehe. Full Scale TRD Dash Quote Link to comment Share on other sites More sharing options...

Gaz6002 Posted November 18, 2008 Share Posted November 18, 2008 Now that is one lovely looking Supra. Well done. As said, you need a restrictor ring. Contact Chris Wilson on here by E-Mail to order. It's not big, so postage won't be silly. Quote Link to comment Share on other sites More sharing options...
