Hey what's up, im fairly new to this forum and I am in the beginning stages of starting my sr20det swap into a 240sx. Well here is my problem. I just bought a 1990 240sx, i know it isnt the DOHC but the motor will be out soon anyways.

From what the guy told me the only thing that is wrong with this SOHC motor is that the cam timing is off causing the car to not start. He said it "cranks just doesnt turn over"

Well, here is my problem...I called the bank for a loan on the SR20DET and I need a co-signer and thats where i am running into problems...So, how could i fix the cam timing just to get this car on the road? thanks for the help

Tell you the truth, I do not know how many miles it has on it, I just bought it this weekend and it is still at my cousins house 45 miles away. It is a fastback. I do not know how the previous owner managed to jump the timing. I will be getting the car to my house in about 2 weeks, at that point i will know how many miles it has

He was redoing the interior when he took those pics. It looks better now. Not a bad deal for $500

Sorry, I should have updated earlier. I have just decided to pull the motor and junk it since it has 250K miles on it. I am going to swap the sr20det motor in there. Thanks for the help anyways though.

i have a problem..i have a 1989 nissan 240sx... cant get it into time no matter what i do. i replaced the head gasket and all timing components as the guides snapped off. so i also had to put a new oil pan gasket on. now i rotoated the cam when it was off the block. (was checking the valves) now i cant get the distributor in time dont know if thats the problem... every time i time it it jumps to cylinder 4. so i figured i was 180 off so i turned the cam a full rotation and still nothing....can anyone help please...been tryin to do it for 4 days now..

First of all you need to set the cam timing properly; once that's set, check the ignition distributor setting. It's not really difficult but you should have an FSM which gives you all the details. I'll just give you the highlights. First disconnect the ignition coil wire, remove all the spark plugs and remove the valve cover. Have someone tap the starter while you have your thumb over the #1 spark plug hole. Once you feel compression, insure that the block timing pointer at the front pulley is pointing to the zero mark on the pulley. Remove distributor cap and insure that the rotor is pointing to #1 firing position. The #1 piston is now sitting at TDC compression stroke. Make sure the engine is NOT TURNED from this point on until everything is reassembled. At this point you need to install a wedge down between the two sides of the chain so that the chain doesn't drop down and disengage from the bottom crank sprocket or it will lose it's timing position. The wedge should have a wire attached to it which will hang over the edge of the timing cover so that it can be pulled easily. Locate the timing marks on the cam sprocket and chain and make sure they match.

I agree with the above, although there might be an easier way...

Here's a picture of my perfectly timed KA24E valvetrain. I'm sure this doesn't help, but it's a pretty picture. Notice the complete lack of power steering, A/C, vaccuum lines, or any kind of spark system on this motor... Fantastic!

timing and fuel i think

now i rotated the cam when i had the head off the car. now the cam gear aint lining up where it spose to be. and i have no idea where the cam lobes are spose to be what valves are open or anything all i know is that the number one cylinder valves are closed. now the car will fire if i soray starting fluid in the throttle body and only run for a moment then quit. but i know its still outta time and i dont kn ow what to do anymore im outta possibilities. i dont wanna pull the whole from of the motor apart again. i dont have the money for any more gaskets. i just put 400 into it for a head gasket set and timing components. what do i do? im stuck.

I pulled the KA24E to replace it with a better powerplant. The new motor is a 1997 KA24DE with OBD-II ECU (FCD removed) and a top mount T04E turbo. Lol, when my timing's off, I just use it as an excuse to swap in a motor that can handle 21psi.
