Yeah, a 3-year old car is generally more reliable than 23-year old car.

More of a joke than anything.

I did a 9 hour endurance race with a 1G DSM. Went fine. Run a 9 hour race with a 100% stock STI and I bet the pistons don't live through it.

Well geeze maybe i should take out the reliability part. Its not like the car is going to be a full on race car.

If you don't build your engine in a sandbox and put on worn out used Ebay parts, DSM's are actually very reliable.

And flog the piss out of it like a dirty old whore.


Start saving for a rebuild Tyler! Factory tunes and internals on these things are scary.

It only took Subaru 20 years to figure out how to make an engine when they came out with the FA20

[dsmDolney]

I agree dsms are reliable if you do them right and accually. Spend the money on reliable parts.

And mike ill be getting another block to start a build on this winter for it

My old panda car was reliable with 90k miles over 400/400 on that motor, stock bottom end that had 120 compression across the board.

That motor got pushed past 500whp and went MN to TX about 10 times.

The pistons just suck on the EJ25. I don't know why Subaru never fixed the problem, but they did some many other things wrong with that engine also that it didn't matter. They had to add an exception to the Rally America rules for the STI in the Stock Production class to allow them to use aftermarket pistons because even though they run race gas and make less than stock HP(due to the turbo restrictor), they still broke pistons. The FA 20 motor seems a bit better and now the turbo is in a much close location to the heads to cut down on the lag caused by the 5 feet of piping to the turbo.
