BlownCorona, another question for you if you don't mind? My steering column has a ton of play at the top (I've had the rack rebuilt so I know that's good). Did you figure out what bearing you need to replace? It sounded as though you had the same issue. Thanks.

I managed to track down my Chevron alignment info. It's on old and faded fax paper! Hope you can read it.

I've also just bought a shroud for the pull through fan (not tried yet though) and will likely reinstall the heater core as another rad. Wish I went for the 3 core civic rad. I'll report back once I've got this thing rebuilt and on track again to test it.

Replied to: BlownCorona Hey mate. i did sort the steering centering by winding in some more caster (mine was set at 0 degrees) that said id be keen to see your alignment numbers. As for the overheating, I've not done too much on that front while ive been trying to buy a house and all my stuff is in storage. i pulled the waterpump hoping to find missing fins, it was rough but not too bad but it could have been causing cavitation so ill still replace it. the radiator was not blocked either. my assumption was that the heater bypass which runs very high nearly above the valve cover was struggling with air bubbles and ill reroute it lower and with a bleed point. your experience worries me to a degree though. i may look to get a larger radiator for it. DaleRous: I actually put a new water pump in when I did the radiator but still no joy. The first track day it overheated, I noticed the belt was chewed up, a bit melted so had obviously been slipping at the high revs. It was 1mm under width. I had hoped that was the problem but I changed the belt and did another track day. This time it only managed 2 half sessions before there was overheating. I'll track down the aligment specs for you and post.

And one of the radiator setup.

Hi mate, I just posted this in your build thread. Sorry, think this is the right place. I also have an 18rg powered chevron that I've had for 4 years. It's a 1989 build. It seems we've come up against some of the same issues! Did you ever sort out your steering not centering properly? The previous owner of my car kept a book of notes for his 17 years of ownership, he sorted his steering not centering with an alignment. I could dig them out for you if you'd like them? My car is the same build, viva front end and holden HR/HQ rear end so the specs should be helpful. Did you ever sort your overheating on the track? I had the same original radiator as yours (it also had the heater matrix hooked up as an additional rad) but it sprung a leak 3 years ago. I also changed to civic half rad, 48mm thick, 2 core, fan mounted to pull through and I got rid of the secondary heater matrix/rad. I did work to create a shroud at the front (between rad and nosecone) to channel air into the rad. It was fine on the street though I felt was marginal. Took it on track and got 4 sessions in before it was overheating. I don't think the gauge is very accurate. The head gasket is now blown...engine is hooked up to the hoist as we speak and engine will come out for a rebuild. If you sorted your overheating problems and could share what you did, that would be awesome! Cheers, Dale 021645352
