SupraDan24 Posted December 14, 2011 Share Posted December 14, 2011 They come up pretty often in the For Sale section bud, and buying second hand will get you more for your money. Thats where i'd be putting my money anyway. Quote Link to comment Share on other sites More sharing options...
mellonman Posted December 14, 2011 Share Posted December 14, 2011 Shiiiiiiiiiiiiit!!!! Running 1.6 seems extremely high on hybrids doesn't it? I heard that 1.5 should be max? 1.6 was the spec i only ran them at 1.4 and had a spike at 1.49 i think it was but i had spiked before to 1.6 it pays to keep a eye out when things feel different Quote Link to comment Share on other sites More sharing options...
Nic Posted December 14, 2011 Share Posted December 14, 2011 Ok, so what model would you recommend now? I like the idea of a digital booster better though as i can play with it whilst in the car! Good threads by the way! Cheers chaps! My thoughts on the subject HERE. The best EBC's available are the HKS EVC VI and the Blitz SBC i-color, not cheap but they make a significant difference to how quickly the turbos spool up and allow you to make peak boost through all gears.

Chris Wilson Posted December 14, 2011 Share Posted December 14, 2011 Removing exhaust restriction to raise boost to the desired level is far less stressful on the turbos and head chamber heat generation than working the turbos harder to make more boost into an excessive restriction with a boost controller. Do you really want to push the boundaries to the limit on an old engine? Just quietly reflect how a £4K bill will go down if you blow the turbos. New ones are well over £1100 plus VAT each, then a full gasket set, oils and labour..... Rebuilt turbos are risky, and you'll probably find the number one turbo already cracked around the wastegate port, making it a very poor candidate to base a rebuild on, new is DEFINITELY the only safe way to go these days.

Good advice, had 2 sets of stock turbos let go, not a cheap fix Quote Link to comment Share on other sites More sharing options...
Jellybean Posted December 14, 2011 Share Posted December 14, 2011 Just want to ask a Q, wheres is the most accurate place to measure Boost pressure? I run my AVCR Boost controller and Defi off the same Vacuum pipe but get differenct readings; I go with the Defi becasue the AVCR just read 0.3 bar at 1.2 on the Defi! Is it common for the sensor's in boost controllers to go? The unit is relatively new and definetly no boost leaks so I presume it is the sensor, I think the cold winter last year killed it.

Chris Wilson Posted December 14, 2011 Share Posted December 14, 2011 One will be reading gauge pressure, one absolute, Google the terms, it's confusing until you what they are doing, we live in an atmosphere of circa 1 bar, some instruments read only pressures above atmospheric, some include this pressure in the readout.

Chris Wilson Posted December 14, 2011 Share Posted December 14, 2011 Best to read boost in the manifold /plenum after the throttle body. If you read it before and after on full boost you can see how restrictive (or not...) the stock TB is. Quote Link to comment Share on other sites More sharing options...
Supra Kong Posted December 15, 2011 Author Share Posted December 15, 2011 So is it easy to adjust the restrictor ring to say 1.2 bar? What needs to be done? Quote Link to comment Share on other sites More sharing options...
Nic Posted December 15, 2011 Share Posted December 15, 2011 So is it easy to adjust the restrictor ring to say 1.2 bar? What needs to be done? The hole in the restrictor ring restricts the exhaust gas flow which in turn restricts the peak boost that the turbos produce, increase the diameter of the hole in the restrictor ring, the restriction will be reduced and the peak boost will rise. What peak boost is the car making in 4th or 5th gear at the moment? Quote Link to comment Share on other sites More sharing options...
