So what are you going to do with the dremel? On my 20r head there was core shift in the bowls which benefitted from porting and the ports stepped down in size about half way in the port which I smoothed the step, amongst other work. I suggest not touching the floor, roughing up the intake to about 40-60 hand finish for fuel atomisation, smooth finish on the short side radius for fuel seperation, and removing and plugging the egr ports in the exhaust. Remove as little material as possible to keep the velocity of the air/fuel mix the same and don't waste too much time on the finish of the exhaust port (polishing), in my opinion (gains vs time spent). Have fun and keep posting, love your threads!
I envy the flexxy thing. My dremel is pretty limited as far as trying to port an intake.
Picked up my timing chain. Ended up being $31. In a Napa box, not an OSK but it says USA on it. Now we need something from say Europe, maybe Australia so we can get a few more nationalities on this build. Has the solid pins like the OSK instead of the rivets like the lousy one I had in the original 22r.New Total: $430.47
Hey Gillesdetrail,Have you done much porting or polishing? Did you test with a flow bench and dyno?Gnarls.
I'd save the cam for pinky and run the stock bump stick
Made some great progress this weekend but I forgot my camera so you guys will have to wait one more day to see what happened...
..I have on that Putney 282 cam, it falls right smack in between Comp cams 268S ("Solid-Performance use. Wide powerband. Smooth idle.") and 280S Magnum grind ("Solid-Best cam for street performance with 5 speed. Good mid-range and top-end.)"...
Thursday night I scuffed and painted the block. I wanted a light color for visibility but they were all out of earth tones and diesel colors at the parts store, so my choices were metallic gold, really red and annoying orange. I chose annoying orange...
Hey you did a better job bracketing that than I did in my mind. I was just glancing at the comp cams website where the duration on the 280S is 242 @ .50. Sadly no, Jim will not share any more information on that cam.I got this: "The lift on both is 433. Duration @ .050 is 226 and the LS is 110." I tried nicely to get more data for you to play with but he said he had been ripped off a few times in the past so he just doesn't give out any more than the bare minimum. He then offered this bit: "The Lobe center line is 105. Yeah other specs are kept locked up. If he had all specs he could go in business for himself or pass it on the forum. You will like the cam." I understand there is way more to it than the lift and duration but we will run it and see how it is. I am staying focused on the "You will like the cam." part . We all know Jim knows his stuff and it gets tested on dynos and in the real world, so I am not worried about the cam exactly. A am a bit curious about using it in the 4runner but that's where I am trusting Glen's experiences and giving it the benefit of the doubt.
