Thats what I'm doing

Hi guys some help needed please I want to degree my tomei poncams B's My setup is flowed and ported head with a set of -5's So from some searching I see setting them 2 degrees advanced on intake and 4 degrees retard on exhaust side, I,m happy to try those settings for the initial setup but would like to k ow if that is 2 degrees on the cams or 2 degrees on the crank Just want to be sure on my starting point and don't want fcuk something up thanks

I sparyed some quick start in the bovs while idling with no change in idle paid so much attention to the timing when assembling the motor but will chack again does anybody know what would be safe degrees to start off with when degreeing these cams could maybe close some of the overlap cam specs below B 260° 260° 9.15mm 9.15mm 110° 115° 0.45mm 0.38mm You can calculate overlap here https://www.rbracing-rsr.com/camshaft.html with these settings Tomei Poncam B Intake 260 degrees 20 BTDC 60 ABDC 110 degrees Exhaust 260 degrees 65 BBDC 15 ATDC 115 degrees

I have initialized the apexi so with stock injectors and mafs you would expect it to idle like normal but no luck, its just beyond rich and adjusting the correction does not lean it out I am thinking that the ovelap of the cams 35degrees is maybe losing some of the air in the chamber and causing the richness but driving at low RPM is also horrid so much hesitation

Thanks Apexi PFC L-jetro with Mine's AFM's

HI Guys some help here please so I have rebuilt my rb26 from scratch, flowed and ported head with Tomei poncam type-b so first install with rc750cc injectors and Mine's mafs brings no joy, idle is rough afr erratic, i can lean the afr out completly and it would still run rich replaced the mafs with old mafs and old injectors still the same problem the car came with bov's that vent to atmosphere I have disconnected them they are not leaking at all when disconnected when driving the car it hesitates alot but when turbo's start making neutral pressure 0bar the AFR starts to lean out then when on boost its start riching up like You would expect and it feels pretty solid on boost with no issues any suggestions could the cams perhaps be out to overlap and cause an issue like this? Thanks hope somebody can shed some light
