We had some guys in , where they paid for uprated fuel pumps to be fitted , but the Installer decided the hot wire process made them to noisy so he doesn’t do it any more , hot wiring ( supplying alternator voltage through adequate cable to support the amps the motorsport pump requires ) even a standard pump can net a massive flow gain on a standard fresh pump , but if you don’t want the noise fit a Std supra pump and wire it according . It seams there’s so much new info on line that the guys with 40yr experience are lost in the crowd . The info is out there you have to go to the right places

Sti running wiseco pistons, a new v7 rods and a set of AVCS heads all for a GC8 type-r . We had to strip nearly 3 engines to illuminate Wrx bits that had been cobbled together. It's faster and cheaper to jump up to the new engines than go through the mindfield of the older stuff , this took Std and tighter ACL bearings to achieve the required oil clearances along with good oil control from a ported 11mm oil pump and block to the Roger Clark sump baffle, should all go along way to the ej20 reliability

Seeing as everyone has to run 1.6 or lower to obtain the motorsport liesence we started with the cheapest engine to get to 200 bhp , 4age 20v , as the come with itb's out of the box and for now it's out the door with exhaust a M4 and our custom crank and cam pickups where cams and Pistons later will take it up to the 200

It's time I better finish up this , took me a while to get my head around the cam timing not use to working on tings with such a short stroke , valve springs were shot to hell only making half the service limit , then people wonder why it dropped a valve , far cheaper to catch in time
