I'm wondering how much are used NSX engines run these days.. and how hard is it to find one in good shape.

I'm wondering how much are used NSX engines run these days.. and how hard is it to find one in good shape.

There are some questions to which I wish I didn't know the answers. :frown:

Depending on what happened to your engine, you may not need an entire engine. For example, if you just bend some valves, it's probably worth just getting the parts and rebuilding. But if you damage the lower end, too, replacing the engine may be your best bet.

Used 3.0-liter engines typically go for $4-6K. At the low end of the range (sometimes even less than $4K), you'll mostly find very-high-mileage engines without a complete maintenance history. At the upper end you'll find low-mileage, well-maintained engines.

Used 3.2-liter engines typically go for $9-11K and you typically don't find high-mileage 3.2-liter engines (because they're newer).

I recently found a nice one within 2-3 hours of deciding I needed one. I had several other offers; in particular, Joe at ERZ had several available in various price ranges.

nsxtasy, Thanks for that answer. I'm debating about maybe picking up a used NSX as a daily and wondering if its worth buying high mileage for cheap vs. low mileage NSX and pay premium.

Another question.. what are the average life span of NSX engines?? Anyone seen 200+K miles? I've had my Legend coupe for past 7 years as a daily and still runs great (225+K).

Barring an unexpected catastrophe (like mine), a well-maintained NSX engine should last forever, basically. There's no need to be concerned about the cost of an engine replacement. You don't think about that when buying a Legend, and you don't need to think about that when buying an NSX.

That being said, I think that the difference in price between a high-mileage and a low-mileage NSX is small enough that the low-mileage car is the better value. Not super low mileage (say, below 20K miles) but below average (average is 5K miles per year).

Anyone seen 200+K miles?

Lots of folks have. There's even some guy on here somewhere who, like a year or so ago, was at 350k+. Most failures aren't from age but from things like oil starvation, over-modding (pre-ignition from lots of boost, trying to get over 380 RWHP with stock internals), over-revving via downshift, etc.

Fellow Prime member Hugh has 179,xxx on his '93 NSX. I know he's trying to hit 250,000 by NSXPO 2007. His engine has never been out of the car and all he does is routine maintanence by the book. The greatest attribute about these cars is their bullet proof reliability, bar some unfortunate, rare, and unexpected failure. Right Ken?? :wink:

You can get te engine rebuilt for about $7500.00 and that is from a dealership. Or you can buy another used motor......I rather just rebuild the motor and add some goodies to it. :smile: Talk to Jon Martin at Cerritos Acura if you have any questions. He is the unabridged version book on the NSX.

It may cost far more than that. Of course, there are rebuilds, and there are rebuilds; for example, if you only need the top end (e.g. valves) rebuilt, it's not as expensive as if you also need the bottom end (e.g. pistons) rebuilt. Bottom line: if it's a lot less expensive to buy a used engine than to rebuild the engine, then go that route and save the money.

Mine is currently there, blew a sparkplug out!
Well not exactly since the frickin coil is sitting on top of it, so up and down and up and down and small pieces in my cylinder and out comes the engine and down to buddy Chris for a makeover!
Its funny how I can laugh at this situation.
A little mad at the last Acura mechanic who took out the plugs three years ago.

Something to be said for doing your own work!!!!! Don't forget the anti-seize on the spark plug threads.......use a torque wrench also!!!!

Spoken from a true aircraft mech! I've never known anyone else to use a torque wrench on spark plugs. :biggrin:

 

[simonprelude]

Really ??

I use a torque wrench on virtually everything ??

Also make sure it's calibrated often.

Refresh, but not rebuild. For example, if your engine is damaged, the replacement of damaged parts is not included in the cost. (For example, I believe the pistons alone list for $750 each.)

I'm not knocking their refresh program. Just don't think you can get away with spending only $4300 if your engine is seriously damaged.

(The Science of Speed factory-spec engine refresh program is described on their website here.)

Sues coming to town today, going to use the torque wrench for sure!
Was just talking about a refresh, and yes, rebuild with broken parts would be a lot of doh rah me!
But if he buys a car with some milage and wants to refresh it, He certainly can do, can do, yes he, can do!
Enjoy the day my friends.

p.s. Yah on the pistons, up here with rods run about 900.00 cdn x 6 = yikes!
Sos has some aftermarket pistons though where you break the old ones off
the old rods and reused them with some machine'n.
