ok so i have just put my new motor in its a b16a now the block has been decked and the head has beeen shaved timing is dead on and its runs like **** no power feels sluggish vtec doesnt seem to be there but no check engine light or nothing oil is full also. i am running an obd0 manifold with obd1 map sensor also it idles ok idle surge which is because of my iac but besides that anyone have any answers now i havent done a valve adjustment but it has brand new valves in i know this has valve adjustment written all over it but that much loss in power? and it sounds like a ****in subaru at bout 1000 to 4000 rpm under a load but not at idle

any kind of tune or atleast a basemap? valve adjustment is a must, shoulda never even started it tell that was done first.

Thats just retarded. New valves and you didn't do an adjustment?

That thing should have CEL's all over by the sounds of it. Fix what you know needs to be done before you ask what it could be.

Check to make sure none of your spark plug wires are mixed around. Also check to make sure the injector plugs are on the right injectors and and check to make sure your tps and map plugs are mixed up.

ok so i did a compression test today and cyl#1 220 #2 220 #3 75 #4 130 how gay we did a leakdown but i dont understand why when you fill the 3rd cyl with air it goes out the throttle body and comes out of cylinder 4? anything

IhateworkingoncaRs

Leaking out the throttle body is a valve problem. I'm willing to bet its entering in the 4th cylinder thru open valves also.

NvUsEG6

yeah but i just put new valves in

IhateworkingoncaRs

Valve adjustments being off can cause valves to be slightly open when suppose to be closed.

NvUsEG6

yeah we did that also idk

IhateworkingoncaRs

Well, lets see here. When cylinder 3 is at TDC on compression stoke(which is what you should have it at to do a leak down) cylinder 4 should be at the bottom of the intake stroke wich would mean the intake valve would be open. I guess a possibility would be a bad leak between the 2 cylinders.

well lmk if i can use a ls head on my b16 block i dont know if it will work or not but lmk just till i get the b16 head fixed

IhateworkingoncaRs

I'm not sure but a b16 head can be modified to work on a Ls block so I'm sure you can go the other way with some modification.
