decat will throw up a CEL on yours anyway, the code could well be a blocked cat. Best bet maybe full decat, y pipe,m fuel pump, panel filter then a map.
Ah k, have you got a budget in mind? Finding one in top nick will be very difficult, but you may be able to find one that needs work, really depends how much you wanna throw at it.
doers give you some time to find the right one, only issue is they will be going up in price now
shame it melted a piston cos it detted its **** off, but mpg for the win,,,,,,,,,,
vpower and momentum isn;t used because it gives better mpg, its used because it has better ron value so smoother more predictable burn
AS performance charge £450 + delivery for the conversion, give alyn a bell. Bear in mind its a proce for hte conversion, not inc the block.
Mines going else where but its just becuase scoobyclinic uses a different machinist and its being done through them.
not really, when you look at the head end its not so open, if that makes sence lol
the biggest improvement is the restraining of the top of the liner/bore
Track work is very different to road work, temps, pressures etc etc are all a massive step up.
The bores/liners on the 2.5 are not very strong when compared to the 2.0 and being open deck they are prone to flex, ovaling and splitting.
this is my 2.5 block being preped for machining and then converting to closed deck,
compare the bores to this,
Also the head stud location isn't ideal.
As said mine is being converted to closed deck,
It still has the same bore and wall thicknes, but is stronger due to the conversion.
There are also alot of other considerations to consider as mentioned, heat is a big biog issue on subaru's when drive hard, oil temps can easily take out an engine. Zen found this out when they cooked their engine in japan time attack the first year over there), that was a purpose built engine and it still fried itself due to 130 degree oil temps.
If your serious about using it on the ring regularly then i suggest you find a tuners whos well versed with race cars and speak to them about best route. Bear in in mind it wont be cheap
