Hi there

KillerB Oil pickup is probably best option and why they fracture,please have look on those threads

And what is involved to fit new or upgraded Oil pickup to working engine,you will need to remove oil sump and then you can replace oil pickup

Please have look on this

The car already has this issue fixed when Zen built it

the shreksta

would they have used an uprated pipe then?

fat-thomas

I would be very suprised if they haven't but I'm sure they have a record of the car and would know.

i will have to give paul a bell and give him the reg number,i want to know what type of 2.5 block was used aswell (odb/scdb etc)

fat-thomas

iTrader: (4)

Open

nevermind........

fat-thomas

iTrader: (4)

????? I know the exact car you are on about

the shreksta

iTrader: (20)

i meant nevermind that its an open deck block matey,shame really but hey-ho

yeah i know you know which car

hopefully going over to see it very soon and leave a deposit.

i will have to speak with paul @ zen either way as its running equal headers and i dont like the sound so will be changing to un-equal and possibly a bigger set of injectors and a map tweak.

would like to know what is the safest power level for that block

fat-thomas

iTrader: (4)

You would be better of just phoning Paul at Zen for advice, I know the car and its a decent motor but it obviously depends on your future expectations for it.

the shreksta

iTrader: (20)

yeah im gonna give him a bell soon.

not alot really,would like around 450bhp from it-the max its ever made was 436 as the 660 injectors were maxed,its been turned down now to 416bhp

it wont be an everyday car as i have a ****ty vectra for the daily grind

As above give the call Paul@Zen,he will let you know for sure if or what is or what will be fitted

Block should be SCBD,if its OEM,if I would use 2.5L lump them I would go with CDB insert from Alyn@ASP

Oil pickup I wanted to upgrade on 2.35L to KillerB Oil Pickup,which have good reviews there

Thanks,Jura

all i know is that on the reciept it states new ej257 block from subaru-doesnt say if open or semi

chubby tom-tom knows the car so i will take it that its an open deck

the car is running a standard location ball-bearing gt3071r turbo so its got a decent blower on there,will speak with paul and see what he says is a safe limit

jura11

iTrader: (7)

Standard block from Subaru EJ257 is SCBD,not open deck,open deck is only on the WRX 2.0L

This is EJ257



On SCBD I would don't go above 1.8bar,maybe bit less,most of mappers don't want to go above 1.65bar on 2.5L

Are you will be running ARP headstuds ?

Thanks,Jura

the shreksta

iTrader: (20)

heres the spec that ive been told matey

2.5 ej 257 engine (new from subaru)
Mahle competition pistons
Carillo rods
V9 crank ( new from subaru)
Balanced bottom end
Arp head stud kit
Acl race bearings
Cosworth head gasket kit

tommy,is this what your classing as an open deck block?

jura im sure i read that the 2.5 wrx was an open deck block

Hi there

Please read this thread

https://www.scoobynet.com/engine-man...abilities.html

EJ257 is semi closed and I think EJ255 is open deck block

This is EJ205 which is Open Deck Block



This is EJ207 which is classed as Semi Closed Deck



Spec is good and should be OK for 450-480bhp,above that you will need CDB insert for sure

Thanks,Jura

Although I know the car I don't know what block its built on,all I can say is its a very tidy car from a decent good reputation builder so you won't go far wrong.

just needs some decent wheels and a set of ap's up front now
