Hey guys just looking for any useful information....
My setup consist of a b16a w/ wiseco 9.1-1 pistons/ eagle rods/arp head studs/ stock head and the motor has about 3500 miles on the rebuild..on 10-14 lbs

Started the other night I randomly boosted on the road and my car randomly started missing and overheating horribly...when I got out of boost I noticed the temp dropped a little bit...

So I got it back to my house changed the plugs and its no longer missing but is overheating when I enter boost..
Did a compression test and came up w/ Cylinder1-120/Cylinder2-160/cylinder3-162-165/cylinder4-150 that was a dry and cold motor test.
Checked coolant and the coolant level is fine,,fan is blowing correctly...Compression test is what scares me the most not sure if it being dry and a cold motor factors in at all.

Just let me know any information you still need as im sure I missed something...and let me know of any ideas you have plz...DD so gotta get it back running smoothly asap....thanks in advance guys

 

Well just tried to drive it a second again w/ my computer connected(s300) and noticed the water temp now immediately goes up when I start to move so I parked it again with it running and not soon after that it started to overheat..so Im hoping its just a headgasket..lmk what you think..

 

Check the thermostat..

 

Checked and its fine

 

Went ahead and installed a new thermostat..going to see if it overheats tomorrow...

 

It could be a head gasket or a water pump you can tell by driveing the car and hit full boost once so there is pressure and than check if your Coolant Overflow Reservoir Tank over fill if it does is a bad water pump or head gasket just change one at a time untill it stop that could cause your over heating problem or not enought coolant or your coolant system has air in it or try to run the car with out a Thermostat and see if that help!!!!!!
