Hello i am new to the scooby scene and need some info ,start of with i have just bought a rb5 with a supposed hole in piston and i have just found out that the ecu has been robbed so my questions are my mate has just offerd me a 2.5 twin turbo legasy engine is this any use at all like using the bottom end with the rb5 heads? or is their to much hasle involved,Now for the ecu ,i take it i need the ecu,blackbox,chip in key and the bit round the barrel or can you get them unlocked and what type of ecu am i looking for?

 

No such thing as a 2.5 twin turbo engine. the legacy B4 engine is a 2 litre twin turbo

 

ohhh ok he just said it was a 2.5 twin turbo so if it is a 2.0 is this any use?

 

Right am not fooking about with another engine now the offer just came up am just getting new pistons,shells,seals,etc but any ideas on what ecu to go for and also how can i tell my car has ppp,were the prodrive sticker would be has a badge saying sti ? sorry if i am asking stupid questions but i have worked on everything apart from honda and subaru.

 

280hp from the factory in manual trim

Yeah a lot of people think they are 2.5 . Unless in was converted its a 2.0litre.

Have a look underneath the altenator if it says EJ20 in the block it a 2litre , EJ25 is a 2.5

Also will need the legacy loom ecu , down pipes etc etc so not worth it, you need an impreza engine from a similar year car

 

Can't be a sti and rb5, rb5 is based on a uk2000, they are Grey in colour. Have a different spoiler and interior trim, alloys was different too. Sti would be a jap import. So
Look for the rear wiper? Does it have rear fog lights? Clocks been changed from kms to mph? Best thing is too look at the log book (v5) and post some photos, imprezas had loads of different ecu's and engine changes.
Best start would be to work out what you have.

 

nana staying away from that then haha i dont no anything about the engine anyway so am better of just replaceing everything so i no what i have got on its own engine, i have a receipt with he car saying it had a new short motor back in 2006/40000 mile ago is this just the same as a new bottom end ? I have rebuilt most engine but never flat 4,s so i have no clue about them

 

Thats what i am trying to do blackvenom i will put some piks up she is a rb5 i have all the paper work going back years she doesent have a rear wiper and clock,s are in mpr and km she is number 374 but she does have a sti badge on the boot the interior is blue and she is a gray color

 

also has impreza turbo 2000 awd rb on docu

I have a 3 plug ecu for your car my car had a ppp pack yellow injectors etc will replace your existing ecu £160 delivered

 

is it unlocked or do you have the chip,box,etc

 

When i changed my ecu it wasnt neccesary to unlock or change any of them... as mine is a very simple spec to an rb5 as mine is a wr sport v reg classic uk which if im correct Will literally just plug in and away you go

 

I live inanchester so if you live close i would be happy to let you come and try it

 

live in aberdeenshire wish i was close ,,,,the lad i got it from is sending me the ecu haha cuz ad drive the **** bak up to get the **** but dont need to go back to jail
