i have this problem too..... and made a thread about it a while ago so you might want to search for it as i think there were some answers there. incidentally i still havent fixed my problem but its better with new plugs and a service...

statewide!!!! thats it. they had that cool spec 2 with FMIC etc a while ago... the may even still have it!

i know people are always talking about which tuning shop to use etc etc well i think ive found mine! cypher had my car and fitted a fuel pump and boost controller, tuned on dyno and replaced a few odds and ends like belts/clamps etc power went up from 165rwhp @ 8psi to 226rwhp @ 12psi so im very happy!! if anyone is still looking for a good tuner then i highly recommend cypher, now its back down to the drags to improve on the 14.8 :burnout:

oscar he running a FMIC, 17psi through an s15 turbo, GTR fuel pump, pod, full exhaust and BOV the cars a bit of a time-bomb at 17psi though! he pulled a 14.001 at 12psi

yeh youve got to be pretty cool to blow up an engine:D hopefully thos days are behind me, it was actually taggart who said hed blown it up.... dodgey b!@#!rd

ok the 910 is in! tomorrow is time for boosting, hope to get around the 200rwkw mark... will keep ya posted! thanks for all the advice guys!

haha his car blew up... my mate ran a 13.4 in his white 180sx with 17psi...

yeh for a car here... c-red or the one down oxford st in leederville, i can remember the name though!!

not to worry, youve got an angle grinder havent you?

****! nice one! they look really good

put me down for that too!

do you modify the existing bracket to fabricate this new bracket? also the R32 one will be different-ish.... how hard was it to fit the new pump rating out of 10.... 1 being dead easy 10 being near to impossible:D

ok so its either the 040 or the 390.... which one is better??

what sort of air/fuel ratios are people here running? im after a balance of good power but also safeguarding against pinging/detonation on a hot day or as a result of some bad fuel, as happened last time if my turbo spikes it will blow the internals as im currently running the std fuel system. am going to upgrade soon but am going to boost it a little as 8psi and 10.8-11:1 A/F doesnt make for a very quick car! ive been told 12-12.2 is the best range for a safe yet powerful air/fuel mixture, any thought/opinions? thanks! adam

also do all these bigger fuel pumps need some sort of aftermarket management system to prevent from running too rich??

what sort of relationship is there between the speed you reach the line and the calculated ET you should have got ie does over 155=14-14.5sec 175=low 13 ??

do you know if bosch have a website/catalogue with all these pumps listed? or is there any order ie hp rating and price...?

at pretty much every single panel beater/spray shop so that would be 100+ locations

ok i rang a performance tuner here in perth, they reckon no bosch pumps will fit the std bracket and to fit a 390 you would have to go for a surge tank setup.... i might investigate the possibility of using a GTR or VL pump, does anyone know of anyone whos used these?

what was the highest boost you ran on the day mack, 11psi? why not higher?!

bosch 390 can fit into the std bracket it you modify it though. i know some pumps are WAY too big and need a completely new bracket to fit... is the 390 overkill?? im only after a 400hp pump... and with replacing the ful filter i just did that on my last service... do you need to replce it again or do they just say have anew filter present cos mines less than a week old!

im looking for a fuel pump upgrade which will fit into the existing bracket without too much messing around. im after one rated to around the 4-500hp mark (nothing too big!) so far ive been recommended the bosch motorsport 390 pump does anyone else have any ideas

youre not going to buy that are you?

yeh i understand that happens at 0.8bar which is around 12psi but why not find some middle ground ie 10psi cos at that boost the car would have run fine and you could have run a better time.... maybe just have to wait for wednesday nights to come back!

0.6bar = 8psi you should be able to run 10psi through the std intercooler no worries
