JohnA Posted April 22, 2005 Author Share Posted April 22, 2005 John there are huge amounts of BS talked in the Supra community, here and abroad. It gets worse the further up the modifying tree you go.It is just a matter of sifting and making informed decisions. I couldn't agree more mate. You can see from my website that I don't suffer fools gladly, neither can advertisers piss all over me and tell me it's raining. Hence my BPU- designation, apart from the stainless exhaust I can't keep any of this 'bpu' crap, it's all useless. What little really works people aren't keen on, because it's no 'bling' and is not glamourous. (Pass on the dump valve for n/a engines mate. Diesels, too. I kid you not!)

Jake Posted April 22, 2005 Share Posted April 22, 2005 Knightrider, start a new thread mate. You need help (quickly) but this thread is about something else so just start a new one. Welcome, BTW Link to comment Share on other sites More sharing options...

Jake Posted April 22, 2005 Share Posted April 22, 2005 Lol ! Jake - I know you weren't being sarcy - but I did find that funny! I see what you mean You're right though, I wasn't being sarcky and the guy IS gonna kill his motor if he's running 1.4 bar on stock turbos and injectors Link to comment Share on other sites More sharing options...
JohnK Posted April 22, 2005 Share Posted April 22, 2005 Sounds like he is hitting fuel cut, so wont be hitting those boost figures for more than a second or 2. I agree start a new thread (quickly). Link to comment Share on other sites More sharing options...
dude Posted April 22, 2005 Share Posted April 22, 2005 very diplomatic I know, been through them, but as more 'hard' evidence comes to light and more people experience first hand, the more accurately this can be weighed... Ill take you out in a single equiped car tommorrow John , its the starter pack as i like to call it , real world stuff , mine is at the shop but having to do some fab work to get the new 'larger' turbo to sit where i want it to so its not running at present , you are welcome to a ride in that when it is just bring spare pants !!! its even made certain people !! hasnt it Paul !!!

JohnA Posted April 22, 2005 Author Share Posted April 22, 2005 Dude, years ago I had a kawasaki1100 turbo, well over 250bhp (limit of the dyno, lol) Lethal, weighed 7-8 times less than a supra. Now that needed spare pants over 6K rpm Link to comment Share on other sites More sharing options...
Toms Supra Posted April 22, 2005 Share Posted April 22, 2005 how much would it cost all in on average? Link to comment Share on other sites More sharing options...
Alex Posted April 22, 2005 Share Posted April 22, 2005 Tom, that totally depends on the spec, and how much you can do yourself. Labour costs a lot! Link to comment Share on other sites More sharing options...
Toms Supra Posted April 22, 2005 Share Posted April 22, 2005 er... I cant do it!! Yeh im guessing nearly 3k including EVERYTHING (the single, emanage etc etc) plus labour? Link to comment Share on other sites More sharing options...
paul mac Posted April 22, 2005 Share Posted April 22, 2005 i have just done this, and done it the hard way meaning i bought all the bits seperate to save money and i enjoy the challenge, but it is still feckin expensive i have a tubular manifold and a T61, i already had a FMIC, AFC, ITC, FSE, 550's, brakes etc so it was the logical step to go single, if it is your long term aim to go single build up the parts over a year or so, i started with a pace intercooler and made the end tanks myself (cost £350 in total) and went from there, i hate to say it and this may upset some of the traders on here but if you go this route get all your stuff from the USA, i would say i have spent £2000 doing this and thats not counting all the supporting mods Link to comment Share on other sites More sharing options...
JohnA Posted April 23, 2005 Author Share Posted April 23, 2005 I've seen a few routes through the States to source these as 'kits' OK, you'll also need mapping etc afterwards, but most of the matching/fabricating work has already been done for you. (Thank God for the car being available in the States as well.) However the purpose of this thread is to evaluate the concept of going single, not the cost of doing so. I like 'mods' that complement the character of a car, not ones that look or sound 'kewl' but try to make it something that it isn't (and eventually nature wins, always) The Supra's claim to fame (so to speak) is the sequential system (only used in the last RX7 I think) which tries to make a 3.0 lt engine behave like a 5.0. Just look at the stock torque curve. Now trying to make it behave like a big two-stroke will inevitably change the character, such a big heavy beast needs power at low revs or else it crawls like a snake until it picks up at silly revs (and by that time you've lost half of the clutch). That's an extreme example of course, I'm sure most 'single' designs try to find some middle ground. Link to comment Share on other sites More sharing options...
Gamer Posted April 23, 2005 Share Posted April 23, 2005 Have you ever taken a ride in a single conversion yet ? I don't think you will find that it "crawls" at all. There is a touch of hesitation, then the instant grin from ear to ear. Link to comment Share on other sites More sharing options...
JohnA Posted April 23, 2005 Author Share Posted April 23, 2005 Have you ever taken a ride in a single conversion yet ? nope I don't think you will find that it "crawls" at all. There is a touch of hesitation, then the instant grin from ear to ear. So you're saying that the low-down pull and midrange are not affected? Or they are affected, but not really missed, considering the high-rev rush? And is that a 'small' single conversion you're talking about then? To see where I'm coming from, I've had people praise the 'true twin' conversion, claiming that it makes more power, better feeling/handling overall, blah blah (which is utter bollox of course, just goes to show how much a different power delivery can deceive the 'seat of pants' dyno) Link to comment Share on other sites More sharing options...

I would not mind having a small shot of nitrous on a progressive controller to help with the initial spool up. All in all though it is still streetable as it is now and I am happy with the upgrade.

JohnA Posted April 23, 2005 Author Share Posted April 23, 2005 Terrys has so much Torque that when it leaves the line the chassis twists !! wrong forum, Pizza boy Just been through this thread from last year Enjoyable, , nice to see people sharing non-trivial info. I wonder if that silly camcover filter is still there --- bad for the braincells, bad for turbo longevity too. Otherwise (unsheilded air filter apart) looks like a neat little project.
