Onnaj's 1998 Celica ST to 4AGE 20V Blacktop conversion, Next project: C160 LSD 6-speed gearbox :) Options

[onnaj]

Follow my topic cause in the next months i'm going to put a 4AGE 20V Blacktop engine in my 1998 Celica 7AFE. I just love the noise and revs of the Blacktop. I was also doubting about the Beams, but that engine was much more expensive, so the Blacktop wil be the one for me at the moment. Thought also about the 1MZ-FE, but it hasn't been done a lot in Holland and the engines cannot be find over here.

So i've order the blacktop with all the ancillaries, i think at least, and through club4ag.com i've ordered an uncut wiring harness and ECU from a 6 speed m/t. I'm going to use my own C52 gearbox.

So will be continued soon.....

Update time with better pix

Have been really busy with washing the head again and again. After it was time for grinding the valves. Yes, there still was some time left What i've done then? What you think of cleaning the intake and exhaust ports with a dremel and a little wire brush. My girlfriend still wasn't home so what i did next what getting started with polishing (not porting) the exhaust side of the head. I don't think it will give me loads of HP, but the air will flow better and get the heat out of it a bit quicker. The inlet i won't touch. The inlet ports are pretty smooth already from the valve guides till the combustion chamber. Only flow that could do a bit better will be the flow from the throttle bodies to the valve guides. If that has any advantage? I don't know. Opinions vary about that, so i'm sticking with the exhaust side.

But again, photo's will tell the story

For your memory, the uncleaned head:
