@Swelegacy can you post some photos just for clarity?

Ah didn't know that ok will follow that up then see if they are happy to ship international - mind you it will be probably cheaper for me to take a short California break with the blocks in my baggage

Wotcha and welcome!!

RA motorsports do a CDB engine off the shelf for about the same price - site appears to be down at the moment though

yup, I would have to see the cost as a research investment as I would be shipping the block back and forth to the US or buying one from them directly - I have seen billet blocks.... soooooo shiny

going slightly off topic but I was researching a US company that resleeves the standard 2.5 block and reckon their product / work significantly increases what the standard block will take power wise without going semi closed or full CDB conversion - I have a link somewhere I think... but was considering that as an option down the line also

Wotcha and welcome - we have forum stands at some of the shows and there are various regional meets - check out the forum section on this subject - if nothing local to you feel free to use the section to set one up in your area

The block I was referring to in this instance is the ej22 with a 2.35 kit and yes the machining work needs to be top notch

you may want to consider a tablet for the apexi datalogging stuff purely for the size / portability etc

What a transformation - great result

Yes there are coil pack conversions you can do to newage items - yes the map could be off but when it was originally completed they would have test driven it / rolling road so chances are it is something that has gone defective since the session however as already suggested get it booked in for a diagnostic session - running mafless wont affect just two gears it would impact across each of the gears and only real problems it would throw up are engine running rich at lower revs / idle so nothing dramatic. ESL solution will retain the code functions and if you can get the ESL software it will list the faults for you as they have a code table included.

with that scoop you will need some bonnet pins - mahhhhhoooosive

Taking the staged approach is cost effective but as Tidgy says if you look at the end state total cost that is realistic - a good CDB stroker short block build capable of 700bhp will cost you about 7.5K with all named / quality components - you can use a lot of your existing engine ancillaries and replace / upgrade as appropriate. A point of note though is consideration for the other bits - yes you can generate the power but keeping your build alive means investing in protection - things like a dry sump system , air oil separators etc - this is where unexpected additional cost can lie.

Wotcha and welcome - plenty of wagon love on here

Wotcha and welcome - great backdrop shot there and in a cracking part of the country to test the chassis out

Wotcha and welcome - look at uprating ARB's and STI spec springs and dampers that should stiffen it up Consider some koni's as an alternative to OEM dampers with Eibach springs https://www.dcperformance.co.uk/uprated/koni-sport-front-dampers/subaru/impreza.html

Wotcha and welcome - great way to get back into it - awesome motor

wow - a little oil contamination then

Wotcha and welcome - feel free to post some shots of your motor - any issues, plans??

nice touches there

Wotcha and welcome - lowered just the right height IMO

I certainly don't want to put you off getting a subaru - they are addictive however have a browse around the site - petrol fuel economy can be achieved if you take it easy with your right foot - although that is a challenge There are a few threads on diesel engines on this site Mr B has been able to share some real world experience about faults with them. If you go for an earlier 2.0 petrol that falls into the lower tax bracket. A remap without changing anything else on the car generally takes out the manufacturers generic map which contains parameters for working in a wide variety of conditions, bad quality fuel / temperature extremes etc. So your motor will get a little more power as Subaru's tend to be set to run a little richer (compensate for crap fuel) leaner mixture is closer to the optimum ratio, generates a little more power, can give better midrange, drive throughout the rev range and potentially better fuel economy. If you are looking at a new motor you will be covered by warranties etc if watch for issues with DPF's, injectors, main bearing (gearbox alignment from factory) How many miles are you planning on doing? Is it mostly motorway or local start stop? Any need to be driving in London?

just make sure it is adjusted the same as existing or else your boost profile will not be the same (eg wastegate opening too early etc)

Wotcha and welcome - what are you planning to do other than the map - exhaust, filter etc? The Subaru diesel lump isnt the best and has suffered with issues - are you set on a diesel or could you opt for a petrol motor instead? The results will vary slightly dependant on state of engine, weather conditions on the day etc but having a remap will give you a setup specific to your motor

JPN stuff is all metric, wont be imperial - couldn't tell you about the material - used to be copper but not sure nowadays
