not this one is it? https://www.gumtree.com/p/subaru/subaru-impreza-2.5-wrx-sti-spec.d-hawk-eye-2.5-black/1161232216

STI has hyperetic (or how ever its spelt) wrx had cast pistons. Both types are a back of crap though to be fair. Hyper is just a heat treated piston effectively. 2.5 short block hasn't changed much since it was first released, its now on revision 4 iirc but the changes were very minor and more to do with casting and additional fixings for things but they are mainly the same engine. Although as mentioned further up there is an open deck and semi open deck version.

Ah fair enough, think a couple of guys on here use martin.

welcome back, if you buy an xv expecting a performance cross over your in for a nasty surprise, but as far as spec and comparing it with other similar cars they are great, me and my dad looked at about 10 different cars when he was looking for a new car (quashqi, juke, kugar etc etc) and none of them were as well equiped or as roomy at the XV. He liked it so much that when he had his rammed off the road (he and mum were fine, pics in a thread in the XV section under possibly DOA XV) he replaced it with another new one.

Purely out of noseyness what garage is it at? As far as forged piston i would say its a must, headgaskets and ringlands are a big failure point on a 2.5 so you don't want to have it rebuilt and find it breaks again and your back to square 1 needing another build. Subaru changed the pistons from proper forged to heat treated cast and there pretty crap by comparison.

As above, if the headgasket on a 2.5 goes you want to be doing the bottom end 100%. Friend of mine went to a well known tuner who disagreed with that and less than 1000 miles after it dropped the bottom end. Personally i'd look at getting it closed decked while its out (i had the 2.5 in mine closed decked), its around £500 (speak to Alyn at AS Performance) so not bank breaking in the grand scheme of an engine but well worth doing. Also means 500bhp is a realistic reliable target if you ever want to got hat far.

wrx and sti's both suffer, neither is any worse than the other. It's pure pot luck whether it goes or not, i know cars that have had 3 engines in less than 10k miles and i know some that have been thrashed yet never failed.

lmao :D

whats the fuel pressure doing when it comes on boost?

swap the pump out as a starter, just because its new doesn't mean its not faulty.

Be very very wary of piggy back stuff, while i don;t know the fcon itself if its like typical bolt on stuff more then likely blow up your engine. 2001 will be ecutek mappable

take it elsewhere, sounds like he doesnt have a clue

So still up on the bay, but price is down to 4750. Advert is the same with the 'economical' truth on how bad the damage is.

welcome

You'll get away with a small turbo upgrade, but sc42 will be too much for the stock engine. much more than a 36 an your gonna need to have the engine rebuilt. How far you go really depends on budget, my goal is a reliable 500bhp so i've got a closed deck converted 2.5, forged pistons, uprated rods, acl bearings, arp headstuds and supertech valve kit in refurbed v5 heads along witha boat load of supporting mods like FMIC, syvecs etc

Dad didn't notice any difference between his 2015 and 2017, although that's petrol

welcome, which dealer did you buy it from?

will be main engine build i expect.

i've run oil coolers on my past few cars, just make sure its thermostatically controlled

welcome

welcome

sweet, glad it was an easy fix

Check your contract paperwork mate, there is normally a bit about reasonable wear and tear which that would be covered by.

are you sure its andy forrest your talking about, hes 400+ miles north of you in scotland.

wont be andy forrest, he doesn't travel for mapping any more. Scoobyclinic do all my work, ;)
