Got a Holden/Daewoo/Suzuki TS20D engine undergoing a rebuild right now. I don't have much of a budget but I'd like to improve the performance while its out. No boost right now. There aren't that many of these engines in road racing/time attack and the TS20's little brother, the 1.5L D-Tech, wasn't real good with oil temperatures. If this one is better I might boost later, but I want to test first. I'm already unshrouding the valves and doing some minor porting.
I already have a CAI and it's a piece of cake to do a header later, so there's no reason to do it now while I'm financially tight.
Any other ideas for cheap/free upgrades?
