Unhappy Modifying 97 2.5?

I read in the FAQ that modifiying the 97 2.5 will shorten its life is this true? Because of the piston design it wears the engine out quicker. I just purchased my Legacy GT and plan on adding alot of mods. I got rid of my Civic because everyone and is dad has one. I was really hyped about upgrading the GT , but not at the expence of the engine. It only has 52000 on it.

Just save a little on the side for another engine and go for it! If you're engine goes, it just means it time to call Paeco industries and get a little juicier one!

Like Mike Sheilds says, "Speed is money. How fast do you want to go?"

Upgrading your suspension is relatively easy. There isn't much you can do about tht engine other than free up the exhaust and the intake. The 2.5 doesn't take too kindly to forced induction, but you can't afford it anyway. Me neither.

Underdrive pulley. For about $130, I got a noticeable midrange improvement. K&N air filter gave me better low-end.

Regarding seriously modding the engine, some people have had good luck and others haven't. There are a couple of spare 2.5l engines floating around for sale in the <$800 range; if you have the cash I'd buy one, mod it while it was out of the car, and drop it in, keeping the stock one as a spare. You can do cams and pistons from Paeco, headers from Jun, a lightened flywheel and stronger clutch from Primitive Racing, and underdrive pulley from JC Sports or Teague's Auto. Then start on the handling...

Try and blow up your engine before the powertrane warranty runs out at 60k. Then they will replace all of the broken stuff and throw in a Phase-II engine block.

Question 60K powertrain warranty

Guys,

I also have a '97 2.5l. What is the time limit on the 60K powertrain warranty? Does this warranty cover shortblock replacement if piston slap is a problem?

Thanks, Doug

subarurabbit - swapping a short block is less time consuming and cheaper overall (less labour) vs. installing new rods and pistons as well as machineing/honing the cylinderwalls.

Default phase II swap

So does this mean that if my phase I block goes, I can swap in a phase II w/ no other issues, ecu, etc...?
Thanks,

there won't be any probs, other than the fact that your tranny's bolts will be too few for the flywheel. No ECU problems etc... your starter may need to be custom mounted too.
