someone!

 

you need more comp. who build this? Jerry built on your siq???

 

i wish. no jerry built did not, im taking it to him soon.

 

up for some help

 

Check with Dr. Jerry himself

 

Do a leakdown test

 

was the engine warm when you did this? fuel disabled? throttle open/closed? how many times did you let the engine turn over? Cyl. #4 looks to be a prob. Is the b20b stock bottom end?

 

maybe put a few drops of oil in it and do it over again a couple of times in a row. see if it comes up and stays consistent or drops every time you do it.

 

if theres no smoke or oil consumption, check your valves make sure there all at correct lash spec. prob around .006 in .007 ex (when motor is COLD)

-s

Leakdown test would also tell you very quickly where the problem is

 

cyl 4? the one next to the timing belt? if so my car is exactly the same 250-240 across and that one is at 220 no clue why

 

do a leak down test also. u can also try to put oil down that cylinder through the spark plug hole and check the compression if the number goes higher them you know that ur ring are gone on that cylinder. i believe thats rite.

cylinder order is 4-3-2-1 from distributor to timing belt.

no, #1 is closest to the timing belt. #4 is next to the dizzy.

 

i kno that dammit
my plug wires labled
was makin sure the way he did it

 

its cool, just for anybody that was confused on this matter when reading the CYLINDER ORDER IS 4-3-2-1 from distributor to timing belt. maybe some newbs will read it and learn something useful.

i did the test with car kinda warm, not too warm didnt want to blow the meter
thanx guys. i will do a leakdown test. shouldnt my compression be higher like atleast 190 or is it because my bottom end has such low compression?
B20B is completely stock time for a 12:1 sleeved bottom end and skunk stage 2 head

 

nah motors with around 9.0:1 and higher mileage are usually around the 150-170 range

 

well what is wrong with the setup?

compression numbers only tell us so much....

 

make sure the car is full warmed up, disable fuel, and open the throttle when you do it.

 

what do you mean by open throttle as in no intake? and the car ran a 15.2 at 95 mph at fontana on race gas and gutted, which isnt right for a b20v. actually what i think happened was the on of the sparkplugs was a 7. which caused cylinder #4 to go. i just don't know what i need to do now rebuild wise, the car runs good at low rpms, but at higher like 5-7 it struggles.

i mean step on the gas pedal while cranking the car to make sure the butterfly valve is open so the cylinder is actually filling completely with air. If you ran the car on race gas with low compression, your probably werent burning all the fuel and the vehicle would probably have run faster on 91 octane. I dont understand your comment about the spark plug causing cyl. 4 to go. If the vehicle runs good at low RPM, and it should, being a 2 liter, but struggles up high it sounds like a fuel issue. You could be running a tad bit lean, which is fine for low RPM operation, most smaller displacement 4 cyl. engines like to run a little lean down low, and its just not getting enough fuel up high. This is all speculation though. You should list a very detailed description of your setup including what size injectors, any fuel mods, etc. etc. if you want me to help you some more.

 

ok.

i felt the race gas was pointless also
hmm Honda Fiend helped me do it, he cranked the car about 6 times, tapping on the gas of course. it was professionally done test

If it helps anything my friends turbo engine checks in at 160 psi on 9:1 comp and it seems fine. Just ask jerry he will help you out and tell him Ernies ( me ) not to work so damn much
