LSA weak points
 

I'm looking at buying a high-mileage ZL1. What are the common failure points on the LSA motor? I'm fairly familiar with GM's engines, just not the LSA. Just trying to figure out what to expect.

The only thing I can think of is the supercharger rattle, but that probably has been fixed. It has been a solid motor, on the car check the struts, they seem to go out early. The rearend if it is making noise, again if yours us high mileage probably already corrected.

I don't know about this. Lots of these cars were modded, beat on and brought back to stock for sale. I would go lower mileage.

Could have the Vin checked or if it has a maintenance history it might help.

What do you consider high mileage?

If you send me the VIN I can run it through the GM warranty system to see what history it has.

If you trade or buy a ZL1 and you have been in that Miata you are going to think you died and went to high performance heaven! These cars are tough as it gets and as said above PM the person your vin number and they will check it out and tell you everything that has been done to that car. Good luck!

For a supercharged motor, they are amazing strength. Ls3 is very good block for supercharging.

That being said gm makes a hell of a lot of v8s. Imo the only things to worry about are supercharger and related components that arent on other v8s (but they are very good, and as much as people are afraid its not that expensive to rebuild a supercharger if need be down the road) and suspension since it has the dynamic mag ride stuff in it.

But you don't need to worry about that stuff cause you will need to be saving money for more tires. They "may" not last too long. This car has a way of slapping on hilarious, huge smile on your face, so much so that you forget how much those roasting tires cost!

100K. Obviously, lots of highway driving. I don't have a vin, but I'll keep the offer in mind. Thanks!

I was trying to remember who did this, there was a guy on another thread wondering the history of a car. Thanks for doing that!

None that I know of. The only weakness will be the high mileage. LS motors are very flexible, and the LSA/LS3 and the LS6 seem to be the best examples of the GM all aluminum LS engines.

Is this a red bay area car?

No. Why?

@Bigtime53, "Miata" is a little misleading. It is a fully prepped, not street legal, racecar. Stock motor due to class rules.

Just asking because there is a high mileage stock one in the bay area. It has been very well cared for. I thought maybe he put it up for sale but I guess not.
