all advice welcome

thanks scott

 

get a roger clakre upratded oil pump or from some like that scooby clinic so on 130-150 quid better in the long run

 

thts cheap where would i find them tht price beacuse they are all nearer the 200 mark

 

maybe they have gone up since i got my a few years ago go on roger clarke web site dude

 

or send your old one to API and have it re-conditioned with the PRV mod and receive it back painted red, dont forget you will also need a new modine.

 

do u know how much this costs mate cos ive been offered a uprated api red oil pump and what do you mean by i'll need a new modine sorry to sound stupid but am new to the impreza turbo ownership lol keen to learn though.

thanks scott

 

i couldn't tell how much one costs but i think around £100 exchange springs to mind,

this is the modine it is oil cooler and is 100% necessary if you have had bearing failure, not cheap either although sometimes you can pick them up unused from e-bay,

As your engine builder said any 10mm pump with a modified Pressure Relief Valve (PRV).

These can be had from:

Lateral Performance
API
Graham Goode
RCM

Just ring around mate and i'm sure someone will sort you out....

 

nice one thanks matey thtswht i was stuck on weather to get 10mm,11mm or 12 but the 11 and 12 are 4 track use thanks 4 the recomendations ive just been offered an api uprated red one for £50 quid cos the lad built lets say a rapid type r and got board and broke it b4 finish so tht'll do me thinks.

thanks again for all ur help people of scoobynet

 

for the sake of a few quid i wouldn't use a second hand oil pump you just cant trust it to be in good order, i dont think the api ones are that much more new.

 

i got a 12mm cosworth one in mine which was £295

 

what differences to do the sizes make? or what applications are they supposed to be used for?

 

i believe they come in 8 10 11 12mm

forget about the 8mm, the 10mm was fitted to classics and i think non avcs newage wrx's and and the 11/12mm were fitted to the new age sti's fitted with avcs heads, although i could be be wrong on the sizes for new ages weather they are 11 or 12mm, your best bet is to ring David at api as he will know better.

 

Its strange that your engine builder insisted you get an uprated oil pump but did not mention the modine!

 

Indeed the modine should be replaced especially if the engine suffered a failure not doing so could result in another expensive rebuild. Speak to your engine builderand ensure this is replaced.

 

cheers mate

 

david at API supplied mine.
