Will parts for the SR20det work in an SR18de?
things like:
Camshafts, Valves, Valve seals, maybe the engine rebuild gasket kit

I don't think many people can help from here, pay your money and take your chance, and check stuff as you go...

i believe the camshafts should work but i was told the valves wont work because the sr20 bore/stroke is different to the sr18...but anyone with any more information would be helpful

scroll down a bit. this is the third sr18/20 comparison thread in a week.

your better off to use the sr20 block and head... sr18 short blocks i have found a waste of time... better power and torque out of an sr20. max torque i think in a sr18 is only around 6800rpm, whereas the sr20 i think is 7000rpm so naturaly the sr20 has the upside.

As i said in another thread, you could use sr20 short block with sr18 cams as they are more agressive.

I beleive you should be able to get a good 130kw (roughly) out of a sr20 with sr18 cam's, bored throttle body, and pod, with good ignition and exhaust.

I don't think that there's a lot that you can do with the SR18DE that you have. I mean, there isn't much more for the SR20DE, but the thing is I personally think that a 1.8L engine isn't made for any sort of aftermarket stuff.

With that said, if you want to or are kind of stuck with that platform (I'm stuck with my SR20DE which is great in a sense), then the best that I can tell you is to get the small aftermarket stuff. For example, I'd get a 2.5" Cold-air intake from K&N or something and then get the ECU flashed. Well, maybe don't flash the ECU. I'm just thinking that there should be a way for you to take off the rev limiter on your engine which will allow you to have more control over it.

In terms of other stuff, I'd suggest looking for mufflers. Greddy and Tanabe are my favorite two to look at. In terms of a nice aftermarket look and not all out performance, go Tanabe. Tein suspension systems might work if you have an '01-'06 platform. I'm sure there's a bit more than what I've stated, but your best bet is to just wait 'till the engine dies and then get a SR20DE, SR20VE, or the SE-R engine (QR25DET?). In that way you're not restricted as much.

Hope that helps.

another options is bolt-on-turbo onto the SR18DE, swap with SR20DET LSD gbox, would make a great machine

Hi
I would like to present myself, just new here, searching for info n getting to know my car more.
Gr8 site and real good feedbacks from all of u... ;-)

Now maybe some 1 has the energy 2 help me out, my case is:
I own a 100nx w a 1.6l, 16v. Saw an add on an sr20, bought it, when I received it, I realized its not an sr20, think its an sr18 after comparing pix on the internet. My knowledge in engines is limited, sorry... so to make a long story short i need advice on 2 things:
1st: how can I make sure its an sr18?
2nd: As I was waiting for the sr20 to arrive I purchased fidanza flywheel,manifolds and clutch....Will be able to use these on the sr18 at all?

Thx for any relies
Mike

Check the engine number. If its not obvious post here and someone will help.

 

[IanH]

here you are ..


The breakdown of the engine code is as follows:

* SR - Engine Code
* 20 - 2.0 Litres
* D - Dual Overhead Cam
* E - Electronic Fuel Injection
* e - SR20DE LEV-version
* RR - Roller rocker motor

 

[100NX]

Thx 4 info ;-)
I searched for the serial number as ur pix show, but no number there. but i found a 5 or 6 digit number beneath the manifold, the 6th digit has eroded if it even is a digit.
i know what the sr20de and sr18de and ga16 codes stands for but i still cant tell an sr18 from a ga16, i only see the air filter being different after comparing. should these codes be on the engines by any chance?
hope i aint too much a bother...
appreciate ur help..

yes its normally on a flange on the block by the head to block joint.

You can easily tell the GA from the SR, there are pics on here.

Simply if the valve cover is one dome its a GA and if there are two visible cam covers its an SR.

the diagrams show the number at the front right near the thermostat housing. look slightly below the exhaust manifold gasket to the right at the clutch end.
