Impreza Inlet Manifolds

[Jon B]

just been lookin at an ej20 block here...http://cgi.ebay.co.uk/subaru-ej20-engine-block_W0QQitemZ230422190245QQcmdZViewItemQQptZUK_CarsParts_Vehicles_CarParts_SM?hash=item35a63b98a5

and i've noticed that there aint any core plugs at rear above bell housing which makes me think the manifolds are water cooled/heated....

would that be correct???

if that be the case then my manifold has blown the core plug which means cheap fix...will any turbo inlet manifold fit a 98 turbo 2000???

[Jon B]

dunno mate its a my 98 uk turbo 2000 classic facelift model.....

would i be right in saying that there is a core plug below the throttle body on the manifold???? the original hard return pipe for the dv runs just above it???

[Jon B]

cheers for that

thing is that when i take me i/c out and look down underneath the hard return pipe for the oem d/v there's a core plug which is fecked but looking at pictures of bare blocks it aint there... just wondering....if its on the manifold or ????... does anyone have an engine that aint in a car that they could maybe look at and give me the size of the core plug???

Can you post any pics up of what you are looking at mate, the throttle body and/or the iacv are the only parts of the intake manifold that has water passing through it.

no probs mate i heard that you know your stuff from stewartyboy....

to describe it....

after removing i/c

look down under throttlebody...you can see the hard return pipe from the factory d/v...

below that is a core plug about size of 10p piece....

looking at bare blocks its not there.....

core plug runs directly below throttlebody and is below the return pipe....kinda hard to get pics cos of hoses and **** in the way....

i'll get pics up the morra...... after i see to jef's avcr

thats the one mate

just that when i look at bare blocks i cant seem to see the core plug

hi, had a look at a couple of blocks i have lying about and cannot find any core plugs, there is a allen key plug to the left of the t/b but don't know if thats into a water way??? only thing that goes across the block is the big alloy water pipe

[john_stevenson2]

The Manifold is not water heated/cooled. The throttle body and Idle Valve are, but this is done via some external piping.

You won't find any water core plugs on the blocks.

looks like i'm gonna have to get pics up.....

the blocks i've looked at didn't have core plugs either....

i'm confused.com.....if the plug isn't for the block and isn't for the manifold then what can it be for?????.....

the core plug goes in the water crossover pipe that sits under the manifold...!!!!
