Everyone is strongly urging me to rering #4 before turboing.
I have a SC61 sitting around waiting for misc parts + fittings to come in.

comments or questions ?

 

+- 20 psi.

I would definantly fix the 163 before installing the turbo. otherwise you'll regret it.

man thats actually pretty damn strong, kinda like a stock itr numbers.. and with such low compression..

 

I ordered the rings, and I think I will just drill ball hone it. If I get even compression numbers after the break in I will be really happy. This was self tuned with an AEM. The A/F is flatter now (12.8) above 5500.

 

the last compression check was at 800 miles. At 1800 miles it has 180 190 200 175. I did this when I got home from work. I also noticed it burns oil when I rev it high, but dosent burn when I drive it normally. I set my shift light at 7500 since I dont really make power above that.
