The CS400 Cosworth uses forged internals to get to circa 395bhp over the 330s 340 ltd models, none forged but max 340 is really as much as you want to test those. I believe your car currently sits at 296Bhp so your immediate options are ECUTEK remap, cat back exhaust, hi flow panel filter (Suggest uprated fuel pump optional) will give you about 340bhp with launch control & antilag. This will give you an idea of the chassis performance with the additional power - I believe you will find it soft, front end will lift under acceleration and there will be quite a bit of body roll on the corners. Steering is not the quickest on your steering rack and as you start to get a shift on you will be crossing your arms more at teh wheel - look to replace the rack with a 15+ STI item You could then look at the chassis, when that can handle the 340bhp how you like - look to the engine As Tidgy said you are looking at a full tear down, replace the bearings, rods, pistons, head gasket and bolts. You will need to uprate the fuel pump and the injectors - an FPR to maintain the right pressure is essential. A turbo which can shift the extra air required as the standard one wont go that high. More air in = more air out - the standard exhaust is restrictive so look at a turbo back option with or without sport cat An aftemarket ECU with associated sensors will help pull the solution together plus the chassis mods you may want to particularly dependant on what you would like to use the car for - track days etc, build on road friendly changes that can handle the 340bhp I dont know what power your semi auto box can handle though? Buuuut then you could go for a sequemtial item and retain your paddle shift What ever you decide - feel free to create a build thread so we can follow etc

....ahhhhh..... So a helmet for xmas then 😉?

Somebody went home and kicked the dog 😁 The first but I am sure not the last 😉

Wotcha and welcome - Unfortunately Subaru do not do a great diesel engine, bearing failures are a regular occurance due to gearbox / crank misaligment - I would look for a petrol option if possible

A price and some photos normally help a sale - GLWTS 👍

Bargain - GLWTS 👍

Next up assembly of the twin injectors. Fuji Racing standard 550's as primaries, this should mean no lumpy idle or hesitation whilst driving at low revs. Injector Dynamics 1700's as the secondaries so on max chats we should be feeding with the flow capability of 2200's hmmm that isn't going to fit.... ahhhh so those red things are held on by the spring clip and can be removed (Thanks to Martyn @Enginetuner) Sad but I did like the look of the Radium finish with the four injectors visible 🙄

Agree with the OEM approach - maintain the stealth, the toucan is probably the way to go 👍

Wotcha and welcome - as above could be a number of things so if you can get some codes that will help this is what I use https://www.ebay.co.uk/itm/ELM327-ODB-ODB2-V2-1-Advanced-Bluetooth-Car-Auto-Diagnostic-Scanner-Tool-Ku/223293585680?hash=item33fd55b910:g:LgYAAOSwkNFcXFYz

Just had mine done - Exedy pink box and standard flywheel, billet oil separator & Piston Pin cover replacement (Fuji Racing) plus gearbox shaft & crank seals replaced which I supplied myself - they dropped the gearbox to do mine. £350 for labour and road test

Looking good 👍

Fitted the cylinder 4 cooling mod, I used the ICP supplied Fuji Racing kit. The kit was no problem to fit other than the usual fight with spring clips that are too meaty for your fingers but are in a location where you fight to get a set of pliers 😆 Plug to be removed Replaced by adapter tube Pipe goes on Splice into matrix heater feed after cutting the pipe a little

Again I found that there was movement of the wheel on the hub not anywhere near as bad as I found on the Silver hatch but non the less its a simple thing that it appears people get wrong - Spigot ring not the correct size The red one is the one that came with the car the grey is the replacement I got for the Silver hatch to correct that issue, only 1mm out but it means the wheel is not solid on the hub. I have ordered alloy items to replace the current plastic items

Ok so after a few miles the oil leak was still there so I pulled the unit. Looks like the core seals have gone so off for a refurb

replacement turbo arrived - couple of comparison shots Standard on the left, SC46 on the right, Garrett in the middle

Selling this turbo due to going rotated Garret setup No cracks, leaks or play in shaft Full details on SC website shop.scoobyclinic.com/index.php?route=product/product&product_id=131 This ran 505bhp with E85 I do know someone who allegedly got 530bhp on his hatch - all with associated mods of course. Looking for £1200 - please note the socket in some of the pictures is not included in the sale 😁

Then at least you will know the car is spot on 👍

Just make sure your rolling radius is the same as your main wheels 👍

Very nice indeed

you might be able to get a loom adapter, will any of these fit the connectors you have behind the console? https://www.dynamicsounds.co.uk/subaru-steering-wheel-interface-adaptors.html

Wow that looks in better shape than my 08 hatch - great platform to start 👍

615 in a fozzie - that is awesome - as Savage said, the fozzie owners on here don't tend to be doing the big hp builds. As suggested a build thread would be great, I would be interested to know more

Shame - there is a member on here who wants a 3.0 for towing his caravan, thought it might have been an opportunity

Looking good - and you know the kit works 👍

Welcome - Sales posts generally do better with photos - could you add some. Does it have a tow bar fitted?
