mikeyb10supra Posted July 13, 2006 Share Posted July 13, 2006 seeing as you a UK spec, you will need a Boost controller + FCD to start with, walbro fuel pump if your stock pump is on its way out and a decent intercooler, if its in anyway knackred change it, I would fit a boost and EGT gauge as well Quote Link to comment Share on other sites More sharing options...
AntD Posted July 13, 2006 Author Share Posted July 13, 2006 Thanx mate,however,I thought a boost controller would only be a necessity for the Jspec. Quote Link to comment Share on other sites More sharing options...
hob Posted July 13, 2006 Share Posted July 13, 2006 Thanx mate,however,I thought a boost controller would only be a necessity for the Jspec. I thought so too, thought the standard wastegate on the turbo was enough? Quote Link to comment Share on other sites More sharing options...
sleeky Posted July 13, 2006 Share Posted July 13, 2006 Have you bought the decat pipe yet? if not i highly recommend the Megan Downpipe I got mine for £60 off Ebay from 2fast2cool and it was brilliant. 3.1" diamater IIRC and very straight....

Homer Posted July 13, 2006 Share Posted July 13, 2006 Thanx mate,however,I thought a boost controller would only be a necessity for the Jspec. Wrong way round mate. A jspec doesn’t need a boost controller since the wastegate is tiny and therefore allows it to over boost. It needs a restriction in the exhaust top bring the boost down to a reasonable level. A boost controller can only increase boost, not decrease it hence it is not required for a jspec to go 'BPU' A UK Spec has a larger wastegate which can better control the boost. As such , when decatting the boost will not run-away like the Jspec. A boost controller is required to keep the wastegate closed to allow higher boost levels. This subject has been done to death.

They're okay, but with the new MOT's they require full replacement to properly pass an MOT or roadside test. Best off getting a 2-piece so you have the option of using a cat (or sports cat in future) Quote Link to comment Share on other sites More sharing options...
Homer Posted July 14, 2006 Share Posted July 14, 2006 stuff BTW Welcome Lee. Nice to see you paid up after years dodging the sign up fee Why didn't you just enable your original account(s) though? Quote Link to comment Share on other sites More sharing options...
Nic Posted July 14, 2006 Share Posted July 14, 2006 seeing as you a UK spec, you will need a Boost controller + FCD to start with, walbro fuel pump if your stock pump is on its way out and a decent intercooler, if its in anyway knackred change it, I would fit a boost and EGT gauge as well The UK pumps flow more (260l/hr vs 255l/hr) and are silent, compared to the noisy Walbro pumps. If you do replace the fuel pump, I'd replace with a new OEM pump personally. Give me a shout if you want prices. Quote Link to comment Share on other sites More sharing options...

Well i only paid up to advertise my aristo But seeing as im starting a huge supra project which will undoubtable end up in a magazine or too in the future i guess its best to base myself somewhere now that i've turned away from Toyota Owners Club btw i forgot the password for my original account lol so i thought stuff it and started a new one Hows the car going?

Jspec Germany Posted July 14, 2006 Share Posted July 14, 2006 Anybody on here running a Bosch unit on a jspec? I've heard from a U.S. supplier that it's a better pump and is not as loud as the Walbro. Quote Link to comment Share on other sites More sharing options...
Feakins Posted July 14, 2006 Share Posted July 14, 2006 When u say the walbro is loud, u mean while the cars running u can actually hear it??? Quote Link to comment Share on other sites More sharing options...
tbourner Posted July 14, 2006 Share Posted July 14, 2006 Yep it sounds like a lawnmower in the boot. Quote Link to comment Share on other sites More sharing options...
tbourner Posted July 14, 2006 Share Posted July 14, 2006 The above is my opinion and shouldn't be taken as fact. I reserve the right to remove my opinion should anyone decide to sue my arse! Quote Link to comment Share on other sites More sharing options...
Feakins Posted July 14, 2006 Share Posted July 14, 2006 Lol, so I guess its best to just get a new standard one when I go BPU. Quote Link to comment Share on other sites More sharing options...
cashpoint Posted July 14, 2006 Share Posted July 14, 2006 couldn't hear my walbro over the Nur Spec exhaust so it not that noisy Quote Link to comment Share on other sites More sharing options...
tbourner Posted July 14, 2006 Share Posted July 14, 2006 No TBH I couldn't hear mine either, and I had no back seat!! Quote Link to comment Share on other sites More sharing options...
Feakins Posted July 14, 2006 Share Posted July 14, 2006 I want to keep my exhaust quiet tho. Quote Link to comment Share on other sites More sharing options...
Mcgoo Posted July 14, 2006 Share Posted July 14, 2006 My soop is decatted with a nur spec and i can still hear mine whining away at times, usually on idle. Its not an intrusive noise though so dont worry about it. Quote Link to comment Share on other sites More sharing options...
Nic Posted July 15, 2006 Share Posted July 15, 2006 If anyone wants price for a UK spec fuel pump give me a shout as I can get them at a very good price. They are more than a Walbro pump, but flow more fuel and are silent. If there is enough interest I could even organise a group buy. Quote Link to comment Share on other sites More sharing options...
Jspec Germany Posted July 15, 2006 Share Posted July 15, 2006 Nic, what about prices for the high-flow Bosch unit for a jspec? Quote Link to comment Share on other sites More sharing options...
Nic Posted July 15, 2006 Share Posted July 15, 2006 Nic, what about prices for the high-flow Bosch unit for a jspec? Bosch being a German company, I'm sure you'll be able to get better prices there, I can only really get good prices on Japanese brands here.
