Trying to identify a motor

[Faldravan]

Ok i have a 1995 240sx with what is said to be a sr20 motor. How do i find out for sure which motor i have? Its a silver top with the oil cap on passenger side of vavle cover. The 2.4 is on the driver side of the valve cover that i have seen. Theres no turbo on the motor so im stumped on what i have and its hard to buy parts if u dont know what u have. So far all the parts that i have checked is the origanl 2.4 parts but there no setup right.(I mean that all the bolt holes dont line up. Mainly the power steering pump.)

Its a KA24DE.

You could Google image the motors and compare. You do have a KA24DE.

Nissan names their motors after displacement.
KA24DE has 24 in it. It is a 2.4L
SR20DET has 20 in it. It is a 2.0L
VQ35DE has 35 in it. It is a 3.5L

I could go on but I think you get the point. The first two letters are the motor family. KA, SR, VQ, RB.
The next two numbers are the displacement. ie above
The D stands for DOHC (Dual Over Head Cam). This means you have two cam shafts instead of one.
The E stands for ECCS (or electric fuel injection). This means you are fuel injected instead of carbureted.

thats an SR20DE.... its the non-turbo'd SR20

You have an N/A SR. SR20DE. Pretty cool!

so the others said 2.4 u say non turbo sr20. if it is the non turbo sr 20 can i put boost on it with out going in it. As long as its between 5-7

another thing how common is the sr20de for parts. And what would it come out of cause the power steering pump has only one bolt that lines up

Wow I think everybody got caught off guard about you having a SR20DE. You can't boost it. Modifications would be needed. SR20DET ECU, harness, TPS, Coil Packs etc.

Some Sentra FWD parts will fit the RWD SR20DE/DET. There's a write up somewhere on the forums.

of course it can be boosted .... just strap a turbo on and give it a tune. cant promise good results but saying "you cant boost it" is extremely false.... but if you want it to run like a stock sr20det then you would need all those modifications and them some more that lobo240sx listed....

It can be boosted, but LOW boost. You've got to remember that's running 9.5:1 compression, which means tuning will be a pain on pump gas, even with everything from a DET, it will have too much timing and will knock.

Maybe if you bolted all the DET gear to it and added a water injection setup, you'd be alright, but I'd still be leery to run more than 7 psi.

Or E85 if you have it available. I have a CA18DET with 10.2:1 compression and have run as much as 18psi on a S15 SR T28 with out issues. I have an HKS T4 turbo kit on there now and have it street tuned to 15psi (waaayy more power than the T28 @ 18) and still no issues with knock or having to retard the timing.
