Ok,... This isnt my 1st built motor that Ive had problems with, however its the first one that Ive had THIS problem.
I bought a 00 GSR with:
STOCK GSR BLOCK
STOCK GSR HEAD
STOCK CAMS
EAGLE H-BEAM RODS
CP 12.5:1 COMPRESSION PISTONS
SKUNK 2 INTAKE MANI
DC HEADER
EXEDY LIGHTWEIGHT CLUTCH & FLYWHEEL
I bought the car for $2500 because the guy that owned it didnt have the time/patience to put it back together (motor wasnt re-assembled or back in the car yet). He hydrolocked the bone stock motor over a year ago and for about 8-9 months he bought parts to re-build the motor. He is a friend of mine so I told him that he could park his car in my backyard until WE built his motor and I'd also help him put the motor back in (i have a shop behind my house to do it in). Things didnt go as planned,.... The car ended up sitting in back yard for 9 months without him so much as looking at it. The last time he was over I told him that he needed to get the car out of my backyard if he wasnt going to do anything with it. He said that he was tired of the headache and asked me if I wanted to buy it from him. I was like..."sure, I'll give you $2000.00 for it". I never thought he would say ok. He did,.... I ended up giving him $2500 for the car and all the parts.
O.K. so I got a great deal right?.... He had already assembled the bottom end so I asked him about all the torque specs and such just to check and see if he had done it right. He reassured me that everything wae PERFECT and that he had taken his time and done everything by the book. Sounded good to me,.... I went ahead and checked the torque on all the mains and cams just to triple check anyways. Everything checked out ok so I went ahead and finished the motor, put it in the car and went to crank it. It cranked up,.... sort of. The only way I could keep in running was to pat the gas. Hmmmmm,... ah-hah,... duh, stupid me. The car had been sitting for a year with 1/8 tank of gas in it,..... BAD GAS!! I drained the tank, replaced the fuel filter and put new spark plugs in,... cranked it up and this time I could keep it at a steady 1500-2500 rpms but couldnt give it more than 1/4 throttle or let off the gas because it would die. By this point Im thinking that it must be a bad sensor or something with all the emissions stuff I took off so I bought HONDATA w/a p-28 and conversion harness (was planning on doing that anyways). I put the HONDATA in and get the same symptoms. I checked the compression and get 180 on all 4. ok,.. theres something DEFINITELY wrong.... it should be 280 or higher right?... I inspected the spark plugs and found oil on all four of them,... oil in the cylinders, and oil on the wall behind the exhaust. So now Im thinking that when the guy I bought the car from put the rings on,.. he either put them on wrong or upside down or something.
O.K., the reason for this thread is to ask all of you guys if you have ever experienced the same thing and if so,.. what was the problem. If you want to put in your educated guess, thats welcome too. Im dedicating ALL DAY Thursday to getting this problem resolved so any help is appreciated. If you know of anything I should check before pulling the head and oil pan,.. tell me please.

Thanks

I found out today that the pistons arent 12.5:1 thay are 11.5:1 .
