Rob_Mitchell Posted May 31, 2013 Share Posted May 31, 2013 So the syvecs is the no1 ecu for the supra. yep!! Quote Link to comment Share on other sites More sharing options...
DaveR Posted May 31, 2013 Share Posted May 31, 2013 What boost pressure was that at Dave? 1.6bar. So the syvecs is the no1 ecu for the supra. Hell yes! Quote Link to comment Share on other sites More sharing options...
sdistc Posted May 31, 2013 Share Posted May 31, 2013 I've had a single turbo for nearly 10 years now and I wouldn't go back to the sequential system. I've driven them since and that artificial lag to 4000rpm no matter what the gear you're in drives me mental. Have a look here for some raw performance stats of a T67DBB - it's a Garrett GT35R unit, and a GTX version would spool even better by all accounts. 50mph to 90mph in 3 seconds is a lot of fun. http://www.mkivsupra.net/vbb/showthread.php?68090-Dual-ball-bearing-turbo I have found that the power my car is pushing out with this setup is ideal. It'll get a bit squiffy in 3rd gear at 70mph, so I can't see why I'd ever want more power, and I feel like things would just start breaking anyway. It's bonkers daft on the road but still perfectly tractable if you don't go balls-out as well. The power is easily controlled by the right foot, the power comes in smoothly but rapidly, it's got reasonable poke below 4000rpm. Fuel economy actually improves slightly off-boost when you go single as the exhaust system is far less restrictive. You can negate that with bigger cams and more overlap, but I've since found that overlap is just bad in a turbo car at all stages so you tune that out with adjustable cam gears. As for reliability, well, it's got that annoying warm start problem but it always starts second go It might depend on how you drive it, but I've had little trouble with the single setup. It definitely depends on parts quality, what you choose to change and what you leave alone, how it's all fitted together and the tuning afterwards. It's no good banging on a fat HKS turbo kit and then using crap oil lines or a MAP ECU, or wiring it up with scotchloks. All the stuff I was paranoid about when I did the install has been absolutely fine because I paid attention to what could go wrong - hoses rubbing, leaks, vibration of wires, water ingress, all that jazz. UK spec brakes are fine, an non-trick RPS clutch is fine (mine is from 2004 and going strong). Stock intake system is fine, drop in 650cc injectors are fine, 600bhp or less is fine. An e-manage will happily run the car if you can get someone who knows how they work. Decent tyres and suspension are a good idea. RLTC is a must have for me, others may think running any traction control isn't manly enough -Ian This. I don't understand how people feel a BPU car is scary or fast, or how 500 hp is, either. But then, I liked my Supra to have enough power to scare me so I respected it. Perfect Supra is, for me, quick spooling 550 whp with road racing setup for brakes/suspension/tyres - simply because you can't use the top end of 600+ almost anywhere legally/safely/responsibly.

sdistc Posted May 31, 2013 Share Posted May 31, 2013 this does depend on what single turbo you have lets say I daily drove my 71mm Garrett 4294R for a year. No issues, except excessive tyre wear Quote Link to comment Share on other sites More sharing options...
Chris Bailey Posted May 31, 2013 Share Posted May 31, 2013 yes chris. sorry should have quoted Standard rebuilt engine with ARP head studs, ARP main studs and ARP rod bolts.
