Really Bad Knock! ):

Just got the car off the trailer. I knew it didn't run I got it for a steal. There is a really bad knock in the engine. I believe that it is a crank rod or a barring in the crank? Any ideas? Also should I try to buy a new shortblock? A whole new engine? or tear the whole thing apart, fix it, and put it back? any ideas???

depends what you want to do long term,
if your just buying to sell then a cheap 2nd hand engine if your keeping it do it properly,
common to knock from 2500 to 2900 rpm.

Im going to be keeping it. and it is not a common knock it is terrible. I can hear the metal clanging and I instantly turned it off until I had a friend listen to it. I want to do it the best way possible money isn't an issue. I want it done right. I can save some pennies. lol

Re: Really Bad Knock! ):

your on about the death knock, like I say its very common on these Ive replaced a few engines for people with this issues,
as said budget is the limiting factor, no short cuts if you want it right,
why not look up a few local tuning shops and have a word what options are available at what costs,
the price of pistons, what crank and what brand of gaskets can really change the final budget costs if your looking to rebuild your lump, are you forging it or swapping like for like ?
are you sticking with the standard turbo or wanting more, it all adds to the cost and needs to be thought about before you start.

Re: Really Bad Knock! ):

I ethier want completely stock or a bump to 300 hp at the least.
and I most likely do the work myself. I have a friend who is going to help me and it isn't his first rodeo on a subie. so what would I need for the bump up? and what am I looking at price wise and what about stock? Should I replace piece by piece or order a nice shortblock?

Re: Really Bad Knock! ):

you need to know if you want a upgrade or not, the not sure mind set isnt going to work,
then budget, I like Cosworth and RCM parts but as Ive said im not sure what you can get hold of easy in your area, do any of your local tuning/engine shops do a short block, ours do, so once you know what power etc you want you can start to look at what you need,

its no good just buying a set of crappy pistons if you then say hmm I fancy 350 or 400 bhp after a few months, do you future proof the build so it could run say 400 bhp even though you dont want this power now ?

as your engine is dead id be tempted to start fresh (short engine wise) then throw your heads / manifold etc on,
Once done get it mapped.

Re: Really Bad Knock! ):

All my parts would have to come online because around here the closest Subaru dealership even is about 85 miles away. And there is one shop I know of that has worked on Subaru before. But my friends went there and they do a very cheap job. they snapped his rims center caps, bungie strapped his battery down and there garage isn't the nicest and I don't believe they have all the right tools. So what can I do for around 2500-3000? Or should I invest in and exhaust and suspension after I get the engine done stock?
