berg Posted April 11, 2016 Share Posted April 11, 2016 Im looking at buying a precision 6266 single turbo kit for my car But it will be a couple of months before i can fund a standalone and fuel system Can someone just confirm providing afr are good that it will run fine with the kit fitted if the boost is set right down temporarily? Everyone on the U.S forums seem to be fine but judging by them stating 550rwhp etc from the setups makes me sceptical I believe supraleeturbo ran his t51r this way for a short time too? Im not bothered about numbers i just need to know it will run fine low boost if the afr's are good After driving the car today my turbo situation is in a worse state and i need the car for may-july so cant afford for it to break hence i cant really wait to fit the kit.

Its not about the boost level its about fuelling for the physical movement of air volume that's the issue. Quote Link to comment Share on other sites More sharing options...
Glanza_Mike Posted April 11, 2016 Share Posted April 11, 2016 I would think as long as your AFRs are fine you'll also be fine, you'll have to do several months of no high rpm driving though as i doubt the AFR's will be fine higher up the rev range even on low boost.

berg Posted April 11, 2016 Author Share Posted April 11, 2016 Thats what i thought ill buy a wideband gauge to monitor it Ive got 2 weddings which the car is being used for aswell as another event so if the current turbos break (which is looking likely) im doomed But i really dont want to go through the aggro of replacing them with oem turbos to then rip it all off again for a single in 2 months time when i can get the ecu and fuel parts lol Quote Link to comment Share on other sites More sharing options...

johnny g Posted April 11, 2016 Share Posted April 11, 2016 Drive on light throttle and don't allow it to spool more than a few psi, and you'll be fine. Quote Link to comment Share on other sites More sharing options...
Nic Posted April 11, 2016 Share Posted April 11, 2016 Everyone on the U.S forums seem to be fine but judging by them stating 550rwhp etc from the setups makes me sceptical US Supras have bigger injectors the same as the UK Supra, in theory they could deliver enough fuel for around 550fwhp but you wouldn't want to try doing that with a stock ECU. After driving the car today my turbo situation is in a worse state and i need the car for may-july so cant afford for it to break hence i cant really wait to fit the kit. I think you mentioned on another thread some smoke at idle has it got worse? Quote Link to comment Share on other sites More sharing options...

I would concur with above and say minimal boost 1bar should be fine. Do you have to upgrade now then rather than waiting to setup a single properly? What's up with your current system?

Ok thanks US Supras have bigger injectors the same as the UK Supra, in theory they could deliver enough fuel for around 550fwhp but you wouldn't want to try doing that with a stock ECU. I think you mentioned on another thread some smoke at idle has it got worse? Ah i see, Yer the smoke has got worse now and has started to appear while driving Ive noticed a small pool of oil inside the turbo pipe for the second turbo also which was not there 2 weeks ago Have you blown your turbos? Seems they are definately worn Quote Link to comment Share on other sites More sharing options...

Definately on the hunt for an aem gauge now Unfortunately i need the car for 3 events in the coming months so cannot have the car off the road, after recent findings im worried about them failing and leaving me stuck so i need to get it sorted before the 14th of may so the option of waiting is too risky for me In an ideal world id wait and fit it all when i have an ecu and fuel setup - - - Updated - - - You definitely need an AFR wideband in their mate to keep track of things.

j_jza80 Posted April 11, 2016 Share Posted April 11, 2016 Buy the turbokit, don't have it fitted until you can afford the ecu? Seems unnecessary to fit it first. Quote Link to comment Share on other sites More sharing options...
Nic Posted April 11, 2016 Share Posted April 11, 2016 Ah i see, Yer the smoke has got worse now and has started to appear while driving If it's just a bit of smoke it doesn't necessarily mean the turbos are going to let go, they could go on for years like that, if it's great plumes of smoke then I'd be worried. Fitting one or both of the cats back in and turning the boost down to stock pressure could get rid of the smoke completely. Personally I'd run it this way rather than fitting a single turbo without a mapped ECU. Quote Link to comment Share on other sites More sharing options...
berg Posted April 11, 2016 Author Share Posted April 11, 2016 Buy the turbokit, don't have it fitted until you can afford the ecu? Seems unnecessary to fit it first. Already explained above the reasons for needing the car, breaking down is not an option and with 300 miles to travel i feel its a risk especially carrying my mates fiance to their wedding, so its not unnecessary, its just not ideal If it's just a bit of smoke it doesn't necessarily mean the turbos are going to let go, they could go on for years like that, if it's great plumes of smoke then I'd be worried. Fitting one or both of the cats back in and turning the boost down to stock pressure could get rid of the smoke completely. Personally I'd run it this way rather than fitting a single turbo without a mapped ECU. Ill give that a try and see if it makes it any better, it was fine until i put the boost controller on, then gradually over the last 3 days im noticing it get worse, its not plooms of smoke constantly yet, as long as the cars running for the up coming weddings i need it for im happy and will gladly wait to fit the turbo Maybe thats the reason its only been 0.9 bar since i bought the car, masking a problem perhaps Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted April 11, 2016 Share Posted April 11, 2016 Ah, sorry I didn't get it. So you're convinced your current turbos are going to die? I have a set of stock Jspecs you can borrow to tide you over if you get stuck Quote Link to comment Share on other sites More sharing options...

I have a set of stock Jspecs you can borrow to tide you over if you get stuck Im not convinced, they could last years, im just worried about them letting go Im going to turn the boost down as advised and see what difference that makes if any Thanks for the offer appreciate it hi mate, yes i ran my single kit for around 8 months and it worked fine just ran waste gate pressure and felt just a bit faster than bpu and all i ran was a afr gauge. was awesome to drive and brill on fuel lol Ok thanks good to hear Mine would be 2 months maximum if i need to do it, time will tell i spose Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted April 11, 2016 Share Posted April 11, 2016 You could rig an AEM failsafe AFR gauge to a relay on the fuel pump, which would cut the engine if it runs dangerously lean? Quote Link to comment Share on other sites More sharing options...
Supraleeturbo Posted April 11, 2016 Share Posted April 11, 2016 Sorry was log in on my dads by mistake, like I said it's more than fine to run it like it and put your foot down I drove it hard for 8 months and was awesome I say do it mate just make sure your afr are spot on, Lee at Srd can supply you one for a brilliant price mate Quote Link to comment Share on other sites More sharing options...
