A question for you guys who have done a turbo setup in a civic/delsol/crx and kept the AC - I have a fully rebuilt turboed b18c1 in a Del Sol and it is a REALLY tight fit with the big turbo and the A/C compressor and fan all crammed up front. The work is all careful and professional (Sportcar Motion did everything).

The weird thing is we're still running hot - but not at idle - only at high speeds or when there's enough load on the engine. Things we're investigating:

-stock temp gauge is wacko
-ecu has the car running lean @3-4K and hence hot
-water pump is dying


hopefully one of these will turn out to be the problem - but if not i'm being told that they may have to pull the A/C. We've already spent so much time and energy to get this setup to work w/AC installed that I would hate to pull it at this point - so if any of you have done tight turbo setups that kept the A/C please give us any pointers you might have to help troubleshoot.

Thanks in advance
chris


PS. The other odd thing is that after the original turbo install the car would overheat in traffic but not at freeway speeds. After switching out slimfan for the stock one and rebuilding the entire engine - it now overheats after ~2-3 miles on the freeway. In both cases the A/C was installed. Huh? Does not compute!

 

check for air bubbles in coolant, also check your headgasket with a compression check

coolant's been flushed and refilled several times and any bubbles bled out - headgasket is literally brand new...!

 

anyone?

 

maybe change thermostat and make sure the fan was rewired the correct way.
