So, I decided to switch classes this year and do a turbo build. I'm hoping for 225 whp and a lot of torque down low. If I make much more than that, I'll have to dial it back a bit. There is a such thing as too much power for what I'm doing. My compression should be 10.9:1. I wanted to use E85 as fuel but the race season will be here in 5 weeks and I'll be lucky to have this together/tuned in time on pump gas.
9-10:1 + tiny turbo = should make for a very very responsive turbo motor/set-up... though i wouldnt be surprised if you went a size up on the turbo to keep the wheels from always spinning....
High comprerssion head with a 22cc chamber ftw! I don't see the point in using a ratio lower than 9.5:1 for a turbo engine but, almost 11:1 is high enough for me. I've never tuned a turbo engine before. So, I figured I might as well go for broke and see if I can tune this one. I hope I don't blow it up.
Sweet! Cant wait till I get my milled head back myself How much did you take off the head to get 22cc? And you dont happen to have pics that shows how the valves hits into the vitara reliefs?
i dont know how much of the beans im allowed to spill so ill just spill a couple, the block was milled .007 to get it straight which put the vitara's .005 above the deck. and as far the head i wont say how much its milled ill leave that to 90civichillclimber, but i will say it looks crazy with the tiny chambers, i have the head in the back seat of my truck right now id take a couple pics but i dont have a camara
I didn't take any pics of the claying. I never think of snapping pics while I'm working. On the stock y8 cam the exhaust valves didn't even touch the clay. The intake valves on the vtec lobe hit the clay but it was so thick we didn't even bother to measure it. The valve mark in the clay was right in line with the relief. I always clay my engines with a thinner head gasket than I'm using for a built in safety margin.
With a head gasket but thinner than the one I'm going to use. I can't clay this engine without a head gasket because the pistons would hit the head.
