I want to share what I've learned about this scam, to help you all avoid getting taken. First, many thanks to Andreas Miko, a forum member for most of this info. Thanks also to Todd C. (his topic "Pics of My New Engine" Toddles82 - 8/12/2001 02:18PM started it all for me)and Ben Davis who helped, and several others who offered suggestions & encouragement. To recap I was taken in a scam whereby a 1.8 liter SR18DE (not available in US as OE) was substituted for the SR20DE, I thought I was getting. 3 ways to tell the difference:
1) Hard but foolproof way - open the engine up and measure the crank throw / connecting rod length. All SR engines (there are at least 3: SR16, SR18, SR20) have same bore, but different stroke, so needless to say, crank throws & connecting rods are shorter, Valves are also smaller on the SR18 than the SR20.

2) Easiest way (unless it's altered as mine was) - Check the engine model stamped into the pad on the front side of block near the #4 cylinder. It should read SR20. If it reads anything else - beware. Mine had last 2 characters ground off, another example had RRRR stamped. An enterprising criminal could grind off all characters and re-stamp SR20, so watch that.

3) Almost certain way - Look for code cast into the Head in half inch high, raised letters, below and to side of distributor. It's fairly easy to spot (on my motor, at least) by sighting between the distributor and the coil. 64J = SR18DE low-port motor. 58Y = SR18DE high-port motor. I'll try to get codes for SR20 & SR16. I think it would be pretty difficult to alter these cast in codes, so this is probably best way to tell.

I'm told it's a pretty common scam -- I've become aware of 3 cases, without even trying. So beware, don't let those B#$%@&ds get you! (or mess things up for the honest engine importers).

Look at the exhaust header too. It will be a 4-Cat-1 if it's a 1.8 liter. It should be a 4-2 header if it's a 2.0 liter.

That's a 1.8 liter header.

I think its more of a mistake rather than a scam. The majority of this board didnt know what that engine was that toddles posted. How is the average reseller gonna know?

Not looking to argue, but I figure if somebody grinds off the engine code, it's not just an honest mistake.

In toddles case, nothing was ground off to my knowledge.

When I helping him out with trying to find info on the SR18, every site that had the SR20DE and the SR18DE for sale, were changing the exact same price.

That's very interesting. I'm wondering why would anybody pay as much for an SR18 as an SR20, why would anyone even want an SR18, and why would importers even list an engine that's less powerful, was never offered OE, and almost nobody's ever heard of? Beats me. Todd's engine had RRRR stamped where SR20 should go, I assumed it was altered, but who knows. Andreas Miko said "this a trick that a lot of importers are doing to make a larger profit because SR18DE motors are not wanted so they get them for 1/2 the price of SR20DE If they erased the # after the SR stamp then there is the bullshit right there."

Andreas, something is not adding up. My old engine head code is 94Y, now the new engine (which is a different port) is a 53J. According to your information they are both US motor.....confused....

Something is Deffinatly not adding up, my new engine which is 53J is a JDM engine, clearly..to be more specific it is a Primera engine. The engine has a completly diferent Header, and the intake manifold did not have the whole for the EGR (Which All US SR20's Have) and the valve cover is gold, typically found on the Primera engine....is it possible that you have you JDM and US mixed around?

Just an FYI on Forum use, when you edit a post, there is a check box that says delete posts.

Unfortunatly, that option is only available for Administrators, it seems. I've tried using the Delete Post option many times, to no avail. The following error message occurs: "Sorry, but only forum leaders are permitted to delete posts." On other message boards, the Delete Post option is available for all registered users.

No problem.
Do you think it would be possible to have that changed, so everyone was able to delete their own posts if they wanted to? That'd be a nice feature to have. I believe FreshAlloy.com has their board set up that way. Thanks.

SORRY GUYS THE 53J IS US AND JDM.

This head 53J will be found on all highport motors US, JDM and Blue Bird Turbo motors. The BB motor being diffrent with SODIUM filled valves that have a 7mm stem verses a non turbo head that has a standard 6mm valve stem.

Do you mind sharing with us who sold you the motor. Hopefully it will prevent people from buying motor from them again.

hey all, i lived in japan for a couple of years. in japan, the sr18 actually puts out more hp than us spec sr20's. the only reason no one wants them is because low torque is directly proportional to the amount of displacement. We in the states are so caught up in trying to get the most power from the lightest engine that we are missing so good motors that we have. but i am one of those peeps too, oh well
