stevie_b Posted May 8, 2012 Share Posted May 8, 2012 Good thread, enjoyed reading that! Unlikely to be the cause of your 100mph issue, but the car might have the 112mph speed limiter fitted: all the Jap ones have it (Japanese law possibly), although that would probably cause the indicated speed to stick at around 120mph ish (speedos are optimistic as I'm sure you know).

mknapman77 Posted May 8, 2012 Author Share Posted May 8, 2012 its not really like its being limited, as it takes forever to get there too, gonna run some injector cleaner through it tomorrow, and change the fuel pressure regulator if i can get one Quote Link to comment Share on other sites More sharing options...
mknapman77 Posted May 8, 2012 Author Share Posted May 8, 2012 id better add that it has no misfire and no unusual noises, no smoke, everything seems fine except that its slow. only engine fault cde that comes up is 42 which i believe is just a speed sensor?

stevie_b Posted May 8, 2012 Share Posted May 8, 2012 You're correct about code 42. That can be safely ignored for the time being. Quote Link to comment Share on other sites More sharing options...
mknapman77 Posted May 27, 2012 Author Share Posted May 27, 2012 Hi all, found the issue! Appears to have both turbos seized solid! Must be a testament to toyota that it ran so well like that! Im now faced with a predicament. Do i replace both turbos and keep it as a twin, or do i just forget it and go single? Where would be a good place to look for a single conversion, baring in mind i dont want to have to get a mortgage to do it! And where would be the best place to get 2 replacement turbos to stay as a twin? Quote Link to comment Share on other sites More sharing options...
mwilkinson Posted May 27, 2012 Share Posted May 27, 2012 Have the stock turbos rebuilt or find a decent second hand set. There is nothing about going single which is cheap. Quote Link to comment Share on other sites More sharing options...
mwilkinson Posted May 27, 2012 Share Posted May 27, 2012 Sorry just seen the part about where to get some turbos. Try any of the traders. I know Paul Whiffin does some hybrids. Quite a few people use CR Turbos. Can get a refurb set for approx £900. Quote Link to comment Share on other sites More sharing options...
mknapman77 Posted May 27, 2012 Author Share Posted May 27, 2012 youll have to excuse my ignorance, but im reasonably new to the supra and turbo world! what are hybrid turbos? Quote Link to comment Share on other sites More sharing options...
mwilkinson Posted May 28, 2012 Share Posted May 28, 2012 (edited) Sorry double post!! Edited May 28, 2012 by mwilkinson (see edit history) Quote Link to comment Share on other sites More sharing options...
mwilkinson Posted May 28, 2012 Share Posted May 28, 2012 (edited) Sorry only just seen this and I am aware you have another thread with similar question. Hybrid turbos are a stock set which have been modified. For example stock j-spec turbos with the ceramic blades replaced with steel or billet blades etc... Worth doing a search on the forum as this topic has been covered a fair few times. The only issue you will find is that historically hybrid turbos were not renowned for their longevity. But, I think there are a number of additional factors involved in that reputation such as increased boost etc.... People have tried to use hybrid turbos to obtain the mythical 500 bhp on a twin sequential setup. As such they are often used in conjunction with piggy back fuel computers, larger injectors etc...

stevie_b Posted May 28, 2012 Share Posted May 28, 2012 Hybrid turbos: I think they're J-Spec turbos that have been re-built with steel turbine blades. J-Spec turbos have ceramic blades. Quote Link to comment Share on other sites More sharing options...

EMPEROR Posted July 9, 2012 Share Posted July 9, 2012 I wonder how I have missed this thread... Great work man! Glad you brought the Supra back to life. Would have been a shame to let it just rot there... Cangrats!!! Quote Link to comment Share on other sites More sharing options...

mknapman77 Posted August 29, 2012 Author Share Posted August 29, 2012 Supra has been running a while now, but it is really lumpy and kind of cuts in and out quite violently in the second turbo? Anyone have any ideas? Want to try and sort it before tax runs out in october as im thinking of taking it off the road and repainting it! Also does anyone know if the paint that they come with is a single stage or a paint/lacqeur? Quote Link to comment Share on other sites More sharing options...
