STI engine

[Aldo the Apache]

What's going on guys? New to the site here. I'm very excited for the ft86 it looks amazing! I'm VERY concerned that they will manage to **** it up before the production car but let's keep our fingers crossed.

So who here thinks it will be relatively easy to drop an sti motor in here? I thought this car was going to be turbocharged stock. Hell when I drive one I might very well find they picked the right motor from the start. But just for S&G who thinks it will bolt up or do you reckon itll need some fabrication?

[old greg]

It will need fabrication.

At the very least you'll need modified wiring harness, custom headers, oil pan, downpipe, IC piping, IC mounting (and/or bumper beam if you want anything of worthwhile size). On the plus side, the EJ257 longblock should bolt right up to the stock motor mounts and bellhousing.

But, there won't be enough room between the engine and the firewall to plumb the exhaust in the same way as it has always been done on the Impreza. The turbo will need to be mounted out front like on a 2010+ Legacy GT. The problem is that the EJ will be ~1" longer than the stock engine (EJ = Timing Belt, FA = Timing Chain), and there might not be enough room left to stick a turbo between the accessory belt and the radiator.

I wonder if any parts will be sharable between the 2 engines. EJ207 and FA20

Where the engine sits

just put a porsche engine in ...and make a custom exhaust to come out from the front fenders.

Just as long as I can spray close spectators with my nitrous as Luda admires my timely arrival I'll be happy.

Okay no but seriously fairly sure there'll be turby ones later down the track anyway. Haven't they already released that there's a possibility of a 1.6T a year after initial release?

What the hell? Does anyone else think that the oil filter that is mounted on the FB20 and concept car looks like a disaster waiting to happen? That looks like it will make a mess of the engine bay. I notice that there is a lip there, but it can't possibly hold all the oil that will come out of that filter?

That was the best thing about the EJ series motors, the oil filter was mounted on the bottom of the motor pointing straight down...

Never seen recent V engine trucks? they have filter like that & it's working perfectly

[Aurex]

I haven't. I don't really pay any attention to trucks at all. I'm also not 100% up to date with current\future Subaru tech.

My concern when I saw the above picture(s) was that the filter would still be full of oil and when you take it off it would drain out of the filter, fill that recessed area and spill down the block.

When you shut the motor off the oil must drain out of the filter then?

Under the oil filter mount, there is a small nipple which you can pull off to drain that catch area. Some put a small disposable bottle or cup directly under it to catch the oil that drips out. Some others have even gone as far as to run a hose all the way down by the oil pan.

Perfect! Thank you sir, for taking the time to explain how it works.

No problem :happy0180:

[Marrk]

Slightly OT: Anybody have a guess as to whether the cams on the FT-86 will be chain driven or belt driven? What does Subaru usually use?

[ichitaka05]

^Expect to have it chain. Older model was belt, but recently been chain
