Om605 compound turbo build, my Corolla Ke70 tracktoy
Hi, I have spacers on the intake valves if it is theese you are thinking of;
They are only on the intake side, this is because the hydraulic lifters only makes about 1mm more lift than oem. The exhaust side have about 1mm more lift, so the lifters take that, and the intake have about 2mm more lift, så they are spaced 1mm
When I was at KM cams and picked up cams, he had taken one N/A cam and one turbo cam and measured them, and he said that the N/A cam had about 1mm more lift, but that the duration or what it is (not my field) made ha cam so much milder, that he could not se any gain in performance using N/A cam. He ment that it might be some slightly difference if you got them timed good, but cams must be grinded to get performance
Now; a little update
Picked up my new driving Chair
And the manifolds have been machined so the flenges are straight, and I was out on a local farm and had them sand blasted. So than I just had to Mount them Here with new coppergasket, exhaust pressure and backpressure on Place
wrapped the last bits
first turbo mounted, and the supportbar on the underside
now it startet to get a bit tighter... The tube to the wastegate was the only tube that was made outside the car, and the only that did not fit in the car..... So had to make som more room with the hammer!
suddenly much more room, Next turbo pleace!
Had to remake the fittings to the oilreturn, it hit with the support bar to the turbo etc. But I made it. Its tight to get Down 2x oilreturn etc. Engine have run with both turbos on This will start building pressure from the first touch on the trothle
Took out the rear axle to get the diff swapped. The oil had a rather fancy color :p
part out on the table
well... dont have to tell you what have made noise here
Had 3.73:1 ratio but are now swapping to 3.54:1 to get it a bit longer
