How much for a STI ver 5 engine?? New or second hand.

Gidney&Knowlesy

Grade A for second hand call Andy on 01663744114; though usually they are few & far between

ALternatively David @ API may have one waiting to go on the shelf

Or source a short block circa £1600

Though best to shop around....

If you are willing to remap the ECU then a US EJ257 2.5 litre short motor is about 1400-1600+VAT landed in the UK, less if you import one yourself. It would also be new. If your STi heads are in good condition this could make a gorgeously torquey motor using very low boost indeed.

would it be a straight swop over to fit a turbo to the 2.5 or does that one already have a turbo fitted to it?

john banks

The short motor is a ready assembled block with crank, bearings, rods and pistons, needs headgasket (std thickness raises the CR to 8.7:1 approx see CarlosH's posts on this here and on 22b). You need to transfer everything off your old block, but beware what you reuse if you had a failure. Check the heads, use a new oil pump. You would reuse the heads if possible, all the ancillaries, turbo, inlet and exhaust manifolds etc.

is it worth doing it just as much as if you have goosed the motor in some way or another? i take it also, that you would be far better using STI internals over standard UK?

john banks

Depends if you want more power and less lag, and if you have the supporting components including ECU, fuel system, turbo to take advantage of it.

John,

"You need to transfer everything off your old block, but beware what you reuse if you had a failure. Check the heads, use a new oil pump. You would reuse the heads if possible, all the ancillaries, turbo, inlet and exhaust manifolds etc."

You should replace the oil to water heat exchanger doughnut if the engine has failed. Like external oil cooler matrix units you should replace this after a failure as you cannot guarantee that you have removed all debris fromt he unit.

I would also get the turbo checked over after an engine failure... there is supposedly a small debris filter in the oil feed line to the core, but this may not catch the smaller stuff, and would need to be cleaned anyway. Also, if molten piston gets as far as the turbine wheel, it will put the core off balance and consequently bugger the bearing.

The oil pump could be completely dismantled and cleaned... the state of the oil pressure relief valve assembly being the issue that may require the pump be replaced.

i've just learned that you used to remap ecutek ecu's. may i ask where you learned how to do it?

john banks

Ecutek training on their software & advice from lots of others, practice, reading, and a lot of prior experimentation with DIY piggyback/monitoring devices and boost control.

this ain't gonna be an easy thing then, to do fairly quick then is it?

john banks

If you want to play with your own ECU, best plan might be to get a Link ECU from BRDevelopments. You will learn a lot from the mapping, and can then tweak it yourself later on as your mods progress. The Link is competent, but also fairly user friendly/adjustable.

honestly?!!!!

take it i would need a laptop and buy the software for it?

AlanG

You can use either the hand held controller or a laptop depending on what chipset is in the car.

You can see how it works on mine if you want.

cheers alang

so all i do is dl the software and get a portable handheld thingamayjig and footer about with it when i have a link installed?

i'm just not technically minded at all!

john banks

In that case get it mapped professionally first, mess about later when you are more informed.

i thought that's what you guy's ment or did you think i had the link already fitted?

Do any of you know where I can get datailed diagrams of a Ver5 STI engine, locating internal components etc. Searched the web but couldn't find any.
Just that I'm not to clued up on the Scooby engines yet!! Might be buying one, but it may have some engine damage.

john banks

Look in the Link ECU manual which has wiring diagram and sensor locations for a start - version 5 suits your model year. Other material on the web such as service manuals has a lot of useful information although the 99/00 Turbo (uk/euro or STi) model year service manual is not available on line that I've been able to find. You can subscribe to a download service for 48 hours or so on the Subaru USA site, which gives lots of service manual info, but again not for this model year.

AlanG

I wouldn't footer about with it if /when you get the Link installed, but downloading the software will let you see what the ECU can do and what items you can adjust.

As John says, if you get one, get it mapped professionally. Over a period of time and familiarisation of the ECU, if you think you are confident about what differences changing the parameters on the ECU can do, then by all means have a go. We all had to start somewhere.

Alan

You can change or view settings in the ECU with either a handheld tuning module or via laptop.Whatever you choose.

S/H STI 6 Engine cost me £2300+ VAT .

Don't Know where from though. As I entrusted garage that fittsd it.


This is in my STI 5 Type R.

cheers lads for all the help. but where can i get a hand held tuning module?

and sg72...who are u asking where they're from in scotland?
