faultless motoring since running the 12, but the clutch was a bit torched so finally thought it was time to replace it.
while the motor was out to do the clutch i fitted a powertune twin scroll manifold with 2 38mm tial mvs gates topped with a gt3076. 82 rear
the old intercooler piping was absolutely terrible. the guy i used was an apprentice fabricator. you can see ho he didnt have the right size tube for the iac so he just welded a nut on and rounded it off.
i bought a welder a while back and have been teaching myself to tig stainless on my other car that I'm building. so i thought it was a good opportunity to make new pipework.
spent the last week and a half making a bunch of stuff, first off i had to modify the dump and make new screamer pipes. it was quite tight getting a 3 inch dump and 2 x 1.5 inch screamers, ensuring there was as much distance to the idler arm as possible. got the dump wrapped in titanium heat wrap, came out very nice in the end.
next was new 2.5" cooler piping and a 3" intake. the old intake setup consisted of a 90 degree bend, small pod and no bov so it suffered from reverberation stalling. basically when you jump off the throttle abruptly the air coming back thru the turbo causes the afm to get some hectic signals and it dumps fuel in and stalls. so to remedy this ive made the intake as long as possible with a few 90 degree bends and a 25mm bov port thats hidden and points towards the turbo/away from the z32 afm. on the plus side, air filter now sits behind the headlight. down side - gotta shift the battery.
here you can see the bov port behind the intake
throttlebody side piping, also with bov port hidden underneath. i have a turbosmart kompact plumb back to use, or if i want the zutututu ill just chuck a bung over the ports and you wont be able to see them.
then made a new hardline to the heater core around the back of the motor as the rubber hose was looking tired.
excuse the absolute mess
next step is to replace the lower rad hose with stainless as its currently 2 hoses joined together. then shift the battery and neaten up the wiring because it bugs the shit out of me. after that it will be time to fire it up and go in for a tune. stock cams will limit the power, I'm guessing it will go 315 ish rwhp.
i have also made a couple other things that i will post up once its out of the shed.
