Forester sti vs JDM 2002 wagon sti

2.35 is the best of the bunch but they are very expensive , you need to buy an ej22t at 1400 before you even start.

2.1 stroker is a good compromise.

Does that extra 25cc per cylinder really make that much of a difference? I guess it all helps.

The increase in torque and spool is much better than you would expect from the 100cc.

I guess it's just enough bump in torque to get the turbo boosting earlier.

So if an FSTi lump needs a 4k rebuild, one could source and fit say a 2.0 from a UK STi Impreza instead? It would bolt straight in?

Loom is all differnnt, heads are different, ecu is different, so basically no.

I can't remember if the 2.5 heads fit the 2.0 block, i don't think they do.

Heads from an 06/07 STi fit the earlier 2.0 models. Do the FSTi have fly by wire throttle?

So not plug'n'play but not beyond possible. Just a but more involved. A complete donor car would no doubt make it easier.

The larger capacity engines will always beat the smaller on torque and power potential. Its just that the closed deck block 2.0 and 2.2 engines are much stronger, the cylinder liners being supported both ends. That's why for power the 2.0 stroked to 2.1 and the 2.2 stroked to 2.35 are so popular.

yes.

Was chatting to a fellow owner at the weekend. He's owned his 2004 FSTi for years and years. It's now covered 170,000 miles and the engine is still perfect. That's been running 340 bhp for most of that time. He had to have the rear diff repaired recently but that's the only real problem he's had.

I'm absolutely loving mine at the moment. Winter tyres and AWD, the thing just grips and grips on any surface.

mine is locked away in a heated garage for winter hibernation probably come back out in the spring!

You're missing out - the FSTi shines more as conditions get worse

[vxr2010]

my 04 is on 150k miles , engine rebuild at 83k miles , other than usual servicing only slight issue is a slow drivers window , still really enjoy the car , snow tyres are on the wagon and that's current car , i have a spare set of snow tyres for the fsti , the wagon snow tyres were cheap and called ecosnow but are a good all year round tyre , the other fsti is hopfully back with its rebuilt engine , i punt not cane the cars around every so often and only when up to temp so sounds like i've been unlucky with engines max boost around 1.3 bar normally 1.25

Not been undersealed yet so need to keep the salt away from it. Infact, its not seen rain in the last 15 months either

Going to do the underside early next year. Have done all the arches while the wheels were off and away for refurb.

I was going to comment that I thought 1.2 bar was the safe boost limit. My car has been making this all summer/autumn. However, a couple of nights ago when the air was really cold and dense it was also boosting to 1.3. Should I be worried?

1.3 is fine on a mapped car

I bet that advice open to contention on a tuned Subaru Boxer

are you selling up? was browsing the for sale section and thought I saw yours

[vxr2010]

as above , 1.2 to 1.25 is fine peak is 1.3 , i've heard 1.35 is high on a 2.5 , but due to smaller turbo if you hit 1.3 you are doing well , the 1.25 being more realistic which improves in cold weather
