My WRX import engined VW Splitscreen -new boy on the block
Hi I wondered if you Subaru experts can help me with my build.
I currently have got hold of a Impreza 94 Jap import engine and wondered what size injectors it will have as standard.
The turbo is a TD05 - H.
I have a TD05-20g ready to fit but I think it might be an overkill in a 50year old bus !
I will be putting this engine in my 63 Splitscreen VW - I'll post some photos of my current 2.5 Legacy install, running Emerald ECU, Sweet as a nut.
Thanks chaps.

Ok cheers. Its not really about power for me more like an engineering challenge
No idea what the bus weighs- 1.6T something like that. Its an empty box
The current engine was mapped at 160 bhp. Not bad from an NA engine with emerald ecu.
So basically what your telling me is i should see at least another 100 bhp.
Blimey that should wake the old girl up a bit.

Tob job, I had been thinking about a similar conversion myself
You will find the 20g quite laggy. What's your plan for charge/intercooling?

I'm going to measure the volume of the std intercooler and go a little bigger. I will fit on the LHS of the bus and a scoop to duct the air.
I'm going to use a N75 valve boost controller from the VAG boys - custom exhaust, 2 bar map sensor, Walbro 255, Cotton Green, remap one and a bit bar boost and may go for the yellows....blah blah blah i'm sure you boys have heard it all before.....looking for something like 250BHP or maybe more lets see what happens. The turbo had to be TOTALLY moved, i've gone for a std stainless tubular manifold then a custom up pipe to the turbo and then v band via custom silencer.
I'm happy to post photos as I go if you are interested.

A few more pics, it's all in the development stage at the mo, the stainless pipe is much larger than required, it just gives the exhaust fabricators a guide of how much room i've got etc...... I know it looks a bit sh£ite at the mo ......I'm still developing guys. The engines off to the fabricators next week for then to fabricate the up pipe.

If i were you i would look to a smaller diameter up pipe to aid spooling, ps this will be an epic thread, keep us posted.
Oh and get rid of those headers mate, oe headers will perform better (ported) than the tubies you have on.

Where abouts in Dorset you from fella? Try out www.dsoc.co.nr (Dorset Subaru Owners Club)
Is the splitty using a subaru gearbox?

The up pipe will be smaller, the welded pipe is 62mm diameter so if they use smaller then it will be clear.
EO equipment is not possible on this build due to the shaping of the exhaust otherwise In would have used it - especially for cost.
Sorry about the confusion

Go for it mate - mines a 2.5 L no issues with cooling as long as you design the install properly. If you can't keep it cool - then you don't have a driveable bus.
Mines in between the chassis rails with custom scoop to duct the air. I've measured everything from temp at the engine, temp at the rad and temp going back to the engine.
I've also measured the wind speed under the bus for my install.
The rad is a 50mm core Cossie one.

Why would he want 860cc injectors ? , it would cost £200 to get them flowed by mark when on the other hand a set of £40 440's will max out his turbo/ engine and gearbox

Yes will do. There will be a short few months delay until i get the exhaust fabricated and then take the ej25 out and then put in the turbo lump.

As said above the tdo5-16G that you have already will make way more than your target 250bhp so i would stick with that and flog the 20g to get some money back. The money from that will easily pay for a set of 440cc injectors. Then that set up will make 340 - 350ish at the fly at 1.5bar assuming the custom exhaust flows ok.
I would be very careful with the boost though as i would suspect all that tourque is going to rip straight thru your gearbox and the reduction boxes on the wheels of the splitty. Unless you already have the Porsche gearbox conversion.
