The mighty GB270
Hi all im very new to all this so please bare with me .
I have just bought my very first Subaru impreza wagon a gb270. I found this car for sale and it was like love at first sight and I had to have it.
Im really interested to now how far can you take these things i.e. performance wise whilst keeping the engine stock because I have heard a lot of story by people talking about chocolate pistons and all that tripe??
and every time I have to do a little modification I have to get it mapped all the time. so even if I change the air filter to a panel filter like a KnN I have to get it mapped and then again if I want to change the exhaust later on its life and so on and so forth. sorry for the rubbish questions but im brand new to all this and you alot have probably heard it all before.
just some advise would be great of anyone would be nice thank you for reading.

Id say panel filter and backbox be fine wont really effect car but yes a remap will bring out a few more horses. Its only when you change to decat/sports cat and induction kits that a remap is needed. If you plan on changing turbo,intercooler etc id either have it all done at once or collect the parts gradually then fit before you get it mapped. That way you will only pay for one map instead of a map then paying for a map tweak as you add uprated parts. Also depends how far you want to go with it. Dont forget brakes and suspension upgrades aswell.

The 300 is probably a limit id go with if you dont fancy rebuilding anytime soon, the 2.5 is a strange engine though could run for ever or it could crap itself even with no mods its the chance you take with it.
They are not crap but just have too many problems ie ring land failure and head gaskets the block is quite weak on them.

Its no different from a normal 2.5 wrx yeh could run a bit more with correct mods but more you push them the more chance of it failing, if you have money put by for a forged engine then yeh id just push it to the max, if it hold great but if it lets go then no big deal as money aside for a rebuild.

Nice one; best looking wagon, best colour imo. Welcome !
You don`t say what mileage and service history it has, which can have a bearing on it`s current engine condition. A custom map as it is will give a bit of peace of mind, but personally I didn't ever buy one because of living with the 2.5l fear; That is not to say that you will have any problems at all. It is still a wrx though, so you will have to change more than just the turbo to push above 290/300, as Jay said.

It's had one owner from new and full subaru history and it's got 83 thousand on the clock. Had timing belt done at 49 thousand. It feels really strong with no knocks or funny bangs starts up with no rattles or anything.

I do like a wagon and have had Impreza, Legacy and Foresters but all JDM and not UK specs.
I would look at getting a timing belt change done as they are changed every 50k or 5 years which ever comes first. The 2.5 is a bit of a stange fish in it's ability to self destruct or last for ages, no hard and fast rule. At 83k the bushes will start to ge tired and are worth replacing with polyurthene.
The GB270 is a standard WRX with some cosmetic nice bits and PPP added, the leather seats being the most desirable. A real shame considering what Subaru could have done.
Most of the points have been covered already but I would bin the coil overs and get a decent struts/spring combo for UK roads. Good quality tyres will be a must and the brakes are uprated so less of a worry.
How much did you pay by the way?

I thought you said it's already got Ksport brakes and BC coilovers? Unless you've added them already since buying it.
Either way it sounds pricey but if your happy with it then that's all that matters. It's a cracking looking car and if it wasn't for the 2.5 engine I'd have got one for sure! Look in the projects thread and someone is currently modding a hawkeye wagon in search of safe gains, should give you some ideas about what's manageable.

Nice looking wagon that pal.
£7800 is a bit eye watering but bodes well for my sh1tbox wagon
As above the 2.5L in the WRX seems to do a little better than the STI and the gearbox is apparently stronger than previous 5 speeds, so that's at least something positive for you.
There was one guy on here a while back with a 2.5L that made it to 240k and there is another in the milage thread with 150k on it so it's not all doom and gloom.
One thing is for sure though if you start modding it, then the risk will be increased as the more boost you add the greater the likely hood of the heads lifting under sustained use.
It's a roll of the dice and the only way to be sure is to go forged but you're looking at £2.5/3k plus while you're at it a new clutch as it would be silly not to, then may as well add a bigger turbo and remap, so all in probably closer to £5k all done and dusted, which really is eye watering and what puts most people on here off.
Anyway enough doom and gloom, who knows you may be one of the lucky ones, those seats are nice.

As its already been said don’t get hung up about the BHP
Torque's makes the difference with the 2.5 engine believe me, make it a very good fast road car following a map
BHP - is for top end speed
Torque’s - are for acceleration

Feel like a good friend died..still in shock.
Subaru garage had me so traded for another Subaru..a Forester. But at least I no longer have to slalom around pot holes!
