thanks, so if the vr wires are not used then do i use the white wire? and where to?

hi, just wondering if anyone has installed an msd 6a to a holden black 202 with delco before? i can't figure out how to hook the dizzy up to the msd, any help is much appreciated, thanks

hi , just a quick question on the fuel ratio now i have taken the manifold off and match ported everything and also ported the rear turbo housing i have now noticed when it receives positive pressure the wideband sits on 13.0 or round abouts instead of 12. it obviously is breathing heaps better but ...

thanks for the diagnosis and it was just an exhaust manifold gasket making all the fuss.

air/fuel ratio is spot on at 14 psi as i have an innovate wideband guage and 42lb injectors so how could it be a lean backfire? and if the turbo has a 1.00 bar actuator then one would think the turbo should be able to handle this boost.

yeah it seems to be getting a bit of a hiding trying to get it right but i guess i am learning from my mistakes. i have the water meth hooked up at 5psi so that should be cooling the charge some what. and the car stiil makes boost normally but just makes the noise, i will pull it off tommorrow and s...

today my turbo spiked at 15psi and a huge backfire came out the turbo and now when ever it spools there is a strange wooshing or whirring noise, any thoughts as to what i have done?

my exhaust consists of the usual 6 bolt rear turbo housing witch is a 2.5 outlet i think then goes into a 3inch dump down to the 2.5 straight through muffler and it then went to twin 2in pipes which dumped infront of the rear tyres. today i removed the twin pipes from the muffler and in place instal...

just a bit more of an update, i had the exhaust cut off at the muffler which is up front around the gearbox area so it got rid of a fair few bends etc and it acted like a new car again and now will lose traction in second at around 8psi as i have wound the boost right down again. so for a start i ob...

yeah right could be the timing which i have been a bit worried about coz this engine is a standard black 202 and i think that the compression for these engines is 8.5.1 so i was wondering how it could handle so much boost without pinging and no cooler, maybe i should be trying for less boost but mor...
