Sorry if this question has been asked a million times before.

What parts do I need to swap out the sohc motor in my 1st gen with a dohc from a first gen?

thanks for the link. I'm actually more interested in just swapping the motors as opposed to just doing the head swap. my motor feels a little loose and I'm lookinng to swap it out for a low mileage DOHC.

 

as long as you get a fuuly complete motor (manifolds, valve cover, egr, and everything) then the only things you will really need is the pcm and wiring harness

 

Pretty funny you'd waste your time swapping the SOHC out for a DOHC when your only going to gain less than 5hp and a drop in mid range torque....lol The DOHC isnt going to be a miracle drug for your Neon, get a flippin' turbo for your SOHC for the same price a DOHC engine costs and gain real power.If your doing itjust to swap a stock DOHC engine in your a fool and I don't care who says the otherway, I wouldn't waste a weekend for a5hp swap and lagy low end torque.

Chances are if your talking about swapping a DOHC head onto a SOHC block with performance in mind you are certainly being counter productive because you will lower the compression and have worse power than a SOHC running 85 bio fuel and by then you mine as well have kept your SOHC engine in.

The only time that swap would be worth it is if your SOHC head was cracked or fkd up somehow.

 

my 1st 4 neons were sohc, now i no longer buy sohc's....only dohc's

 

I'm not looking to swap for power at the moment. I want to swap because my motor is on it's way out. If I'm going to go through the trouble of doing the swap I might as well swap to a DOHC as it seems power modifiers are easier to obtain than SOHC parts.

That being said...If I swaped in another SOHC with DOHC heads will I still need to change the wiring harness and will a DOHC turbo setup than fit on the motor?

 

You gave up on the SOHC. The DOHC is a good enigine but I wouldn't swap, because both engines have about the same potential.

 

always hating on the DOHC

 

the dohc turbo setup will then work....you might need to extend some wires, but thats about it....

only remember that it wouldnt be to wise to swap a dohc head on a sohc block if you dont end up going turbo since the lower compression will drop your N/A power
