jamesmark Posted September 5, 2007 Share Posted September 5, 2007 Stock is 0.7 ish If doing BPU you will run up to 1.2 bar, however it all depends on what condition your turbo's are in on how safely it will run at that. As previously mentioned you will also require FCD (not HKS) New SMIC or FMIC (FMIC is pointless for BPU) Restrictor Ring (best to go for 1 bar and use a boost controller to raise to 1.2bar) Quote Link to comment Share on other sites More sharing options...
mak07 Posted September 5, 2007 Author Share Posted September 5, 2007 can i ask why not HKS? also where can i get a 1 bar restrictor ring from? Quote Link to comment Share on other sites More sharing options...
jamesmark Posted September 5, 2007 Share Posted September 5, 2007 HKS is not the best when it comes to FCD's, the Greddy unit is better and if you can find a Thor unit then they are the best. FCD incase you do not know allows you to raise the boost past 1bar as the stock ecu cuts fuel to the engine if boost goes over 1 bar. and as for buying a 1 bar resrictor ring, I have a brand new one for sale http://www.mkivsupra.net/vbb/showthread.php?t=122310 Quote Link to comment Share on other sites More sharing options...
mak07 Posted September 5, 2007 Author Share Posted September 5, 2007 i have replied,i want it if itll work on a totally stock car Quote Link to comment Share on other sites More sharing options...
jamesmark Posted September 5, 2007 Share Posted September 5, 2007 Ok to get more power out of a stock car apart from going single/big twins is BPU. You will require to do the follow Double decat (remove both cats) Cat back exhaust FCD IK24 spark plugs boost guage Walbro fuel pump Restrictor ring 1.0 bar or 1.2 bar SMIC or FMIC Boost controller to raise the boost to desired 1.2bar Dunno if I have forgotten anything, keep the stock airbox.

mak07 Posted September 5, 2007 Author Share Posted September 5, 2007 im limited at 121 mph so will a FCD delimit me? btw cheers for the info and i will have the restrictor Quote Link to comment Share on other sites More sharing options...
jamesmark Posted September 5, 2007 Share Posted September 5, 2007 im limited at 121 mph so will a FCD delimit me? btw cheers for the info and i will have the restrictor You will require a delimiter/covertor, again the Thor unit is no longer made. I do not know what other SLD is available, contact jezz he owns a breakers I am sure he will be able to sort you out. Maybe an idea to buy some new dials too. If you want that resrictor ring just PM me. Quote Link to comment Share on other sites More sharing options...
tango Posted September 6, 2007 Share Posted September 6, 2007 Hi guys, just checking, I have a manual boots controler but Im still geting fuel cut on my tt, my question is if I get fcd to pass the fuel cut, will my stock engine going to run lean or will it be safe to run as the fuel just stock. cheers Quote Link to comment Share on other sites More sharing options...
tango Posted September 7, 2007 Share Posted September 7, 2007 Hi Jamesmark, hks fcd any problem? whats wrong with them, I was going to buy a 2nd one. Quote Link to comment Share on other sites More sharing options...
jamesmark Posted September 7, 2007 Share Posted September 7, 2007 I have read that they can stop working, short out iirc they also completely remove fuel cut which is not good. However with the amount that are sold it is few and far between. Buy the Greddy one. Quote Link to comment Share on other sites More sharing options...
tango Posted September 7, 2007 Share Posted September 7, 2007 Well, I just bought a greddy bcc, a bit more expensive then the 2nd hand £50 hks fcd, mine tt is just stock, and I just want a bit of fun around 17psi without the fuel cut, just a bit annoy when its cut in. will my stock tt cope with around 17psi, I mean fueling and turbo etc.... cheers Quote Link to comment Share on other sites More sharing options...
jamesmark Posted September 7, 2007 Share Posted September 7, 2007 Yes as long as you have the supporting mods, i.e. restrictor ring, new smic, optional but will help is a fuel controller and Apexi AFCR (I think thats the letters anyway) as you will run rich.

tango Posted September 10, 2007 Share Posted September 10, 2007 Hi there, I got it fitted, it work, that no more fuel cut when hit 17psi, I just measure the voltage before I fitted it, when on it just feed 4.1v constanly, really you can do just with some sort of voltage regulator to give out 4.1v will do. thats all it does....... cheers Quote Link to comment Share on other sites More sharing options...
