Guest Usmann A Posted April 21, 2003 Share Posted April 21, 2003 The 2G price some of you quote, is this from JPS? and that must be for stage 1, that doesn't include fitting does it? Adam, I was merely suggesting, another route which had come into me head, where can the info for the TO4Z be found? What about one of the smaller SP turbos?

dude Posted April 21, 2003 Author Share Posted April 21, 2003 Usmann I believe Leon charges £1500 for the stage 3's and £350 fitting . John:flame Dev Quote Link to comment Share on other sites More sharing options...
Guest Usmann A Posted April 21, 2003 Share Posted April 21, 2003 Thanks, so are you proceeding down that avenue? Or...big singles Quote Link to comment Share on other sites More sharing options...
dude Posted April 21, 2003 Author Share Posted April 21, 2003 looks like its gonna be the hybrids , i will have a chat with leon on friday and i'll be able to make my mind up then . John:flame Dev Quote Link to comment Share on other sites More sharing options...
Guest Usmann A Posted April 21, 2003 Share Posted April 21, 2003 If me dad runs the hybrids, does he need to change the injectors to 550cc ones?, he's already got a new fuel pump and safc. Leons price seems very good. Will hava a chat with our tuner, then if no luck were shifting to JPS. Quote Link to comment Share on other sites More sharing options...

ChrisR Posted April 21, 2003 Share Posted April 21, 2003 Not sure if this is relevant. Taken from a link on Celica GT Four website regarding Turbo Upgrades. Obviously there talking about upgrading a single from the GT Four but i think the explantion regarding the different Hybrid stages could be of some interest -: Here Quote Link to comment Share on other sites More sharing options...
Matt Harwood Posted April 21, 2003 Share Posted April 21, 2003 Originally posted by Darren Matt was your car quickest from standing start? Darren At Pod on the 6th, yes. B But there's a guy on here called Robbie, he has hybrids and his time was only 4 hundredths of a second slower than me, and at present, his boost controller is plumbed in incorrectly. - Should be interesting next time. Incidently, his car's an auto too. The manuals seem to have difficulty getting off the line well with road tyres. Quote Link to comment Share on other sites More sharing options...
sinbad Posted April 21, 2003 Share Posted April 21, 2003 Leon's Stage 3's sound very tempting. What else would it be prudent to do at the same time on a UK Auto Car. The car would be run on the road only and I'm not into throwing good money away so what else is really required. Quote Link to comment Share on other sites More sharing options...
dude Posted April 21, 2003 Author Share Posted April 21, 2003 Usmann I think you will have to fit the uk injectors to be safe Paul you couldnt have hybrids the acceleration would make your bag split! John:flame Dev Quote Link to comment Share on other sites More sharing options...
Thorin Posted April 21, 2003 Share Posted April 21, 2003 Originally posted by Terminator Has anyone got any data on the torque, power, rpm delivery bands ect for the various levels of Hybrid. This would be very useful, does anyone know? Perhaps someone could ask Leon if he knows or could find out from his turbo guy? Quote Link to comment Share on other sites More sharing options...
MONKEYmark Posted April 21, 2003 Share Posted April 21, 2003 people are very cagey about specs on hybrids. its like its top secret stage 4`s or the best are about £2200 is 450bhp-500bhp about right for hybrids. how many people on here have hybrids Quote Link to comment Share on other sites More sharing options...
Thor Posted April 21, 2003 Share Posted April 21, 2003 It has been said time & again, that Hybrids are most viable once the stockers give up the ghost. 500 bhp is possible. You will increase lag with each stage as the wheels get progressively bigger. Stage 3's are excellent. Haven't tried stage 4's but the report is they are awesome but laggy.

Thorin Posted April 21, 2003 Share Posted April 21, 2003 If nothing else it would be useful to know the trim sizings of the different stages. Quote Link to comment Share on other sites More sharing options...

Branners Posted April 21, 2003 Share Posted April 21, 2003 I have been in a car with stage4s and it didnt feel much laggier than a normal UK spec, infact it wasnt noticeable from the passenger seat, might have been if I was driving.

Thorin Posted April 21, 2003 Share Posted April 21, 2003 At what revs does the second turbo kick in on a standard UK Supra? Isn't it later than a J-Spec? Quote Link to comment Share on other sites More sharing options...
Branners Posted April 21, 2003 Share Posted April 21, 2003 it is indeed later. There will be lag compared to an import, the ceramic turbine on the import is very light so spools up easily, the internals on JPS stage4s are 'considerably' larger but have been built to be as light as possible for their size.

Branners Posted April 21, 2003 Share Posted April 21, 2003 well my UK kicks properly at 4,200rpm, my import was at 3,800rpm I think. JB Quote Link to comment Share on other sites More sharing options...
dude Posted April 21, 2003 Author Share Posted April 21, 2003 And the stage 4's ?????, would the fact ive got a sbc-id make any difference as the gain can be used to bring in the turbos sooner but by how much >???? John:flame Dev Quote Link to comment Share on other sites More sharing options...
Thorin Posted April 21, 2003 Share Posted April 21, 2003 Mine kicks in properly at around 4200 too. So unless there's something up with mine there's not a lot in it. Quote Link to comment Share on other sites More sharing options...
Matt Harwood Posted April 21, 2003 Share Posted April 21, 2003 My stock J-spec ceramics definatly come in at 3800rpm. I stand to be corrected but I think a boost controllers gain just help to bring them in faster not earlier. (ie, come in at 3800 and full boost by 4200, and with a higher gain, come in at 3800 and on full boost by 3900... I believe... Just an example BTW) Quote Link to comment Share on other sites More sharing options...
Ian C Posted April 22, 2003 Share Posted April 22, 2003 Coming in late to this thread, here are a few bits of relevant info. I have a 6spd hybridded-up Supra and it was hopeless at Pod in 1st and 2nd gear. This is probably down to very stiff suspension, very stiff tyre sidewalls, and crapulous grip levels at pod. It was very frustrating as I've done enough traffic light grand prix's/standing starts to know it will accelerate better than that on a proper road surface My terminal speeds were 114-115mph, with no real grip until 3rd gear/about 50-60mph. That should give an indication of what hybrids will do for your power when set up reasonably well. I didn't see a higher terminal speed from any of the other Supra timing slips I saw on the day (not that I saw them all), Matt, what was your terminal speed like? Anyway, don't think for a moment that hybrids sacrifice midrange/bottom end for top end power. I don't want to go big single as I love the drivability that the sequential setup gives. The first turbo still allows you to ease away from people in 6th at 1500rpm, and with a 6spd you just drop down a couple of gears if you really need both turbos at once Having driven my car with j-spec and hybrid turbos on I can say they are a bit laggier, such as about half a second more spoolup time. As long as you change gear quickly you can keep them on song as well, with no percievable lag. Changing up at 4000rpm is a no no though as at this point all the plumbing is in the middle of single to parallel transition, so everything takes an age to get spinning again, compounded with the extra lag of the hybrids. If you go for hybrids, make sure your fuelling and intercooling is OK, get the fuelling properly sorted and checked, and get an EGT gauge fitted before going over about 1.3bar. -Ian Quote Link to comment Share on other sites More sharing options...
