service 03 wrx blobeye

Tmoro im going to service my car I want to change the plugs what do you recommend,going to change fuel filter,also I noticed that the gearbox oil level is low can I top it up.any advice please.

I use NGK iridiums mate, if your changing box oil I'd drop it and refill with new and p whilst it's up I'd do diff aswell

NGK PFR6B for standard and PFR7B if modified I believe

NGK PFR6B or 7B plugs. Cant member which is suitable. Think 6B though.
People on here recommend miller oil all round but its personal preference.
For the gearbox unless your draining it all out just top it up with (i think) 75w90 gearbox oil, mine was low before so i topped it up by the gearbox dipstick located under the intercooler.
Hope this helps, others will correct me if wrong lol

mine has had a uprated exhaust and filter but doesn't seem to been mapped do i need this done now .when I put my foot down it hesitates a bit .

That's what mine does but I have not changed my plugs in 3 years

Could be numerous things, plugs,ht leads,coil, boost solinoid lol
I change plugs every service

^^^or sell the car   

lol ive checked it out no fault codes .I just got rid of a focus st with a stage 1 remap about 270bhp.i would be happy with the same this is a learning curve for me.

anyone local to check these out boost etc

anyone used durham remaps he said he could do it for 250

There are a few recommended mappers on here I would stick with them

Yes mate but there are regular mapping sessions run down here every 6 - 8 weeks

Andy Kindon gets Bob Rawle up to Chester Le Street
GIPA gets Andy Forrest to LG MOT Boldon

to name a couple

ok so if I do that what do I need on the car.what am I looking at price wise.

remember its new to me so go easy lol

Level 1 260-280 bhp

Full Decat or Sportscat exhaust from turbo back 2.5 or 3” bore
Ecutek Custom ECU recalibration (similar to PPP)
Twin boost set up for high/low power switchable in-car
Walbro 255 l/hr uprated fuel pump
K+N panel filter



Level 2 290-310 bhp

Full Decat or Sportscat exhaust from turbo back 2.5 or 3” bore.
Decat uppipe Pre turbo
Walbro 255 l/hr uprated fuel pump
K+N panel filter
Ecutek Custom ECU recalibration
Twin boost set up for high/low power switchable in-car
AFP 04-H custom ported hybrid turbo
High Flow multi spray fuel injectors 550cc (380cc as std)
Uprated turbo to intercooler 'Y' pipe
NGK PFR 7B uprated spark plugs



Level 2(a) 300-320 bhp

Substitute VF34/35 or TD05-16G turbo in place of AFP04H for additional 10-20bhp but with slightly later turbo spool up.


Level 3 360-390 bhp

Full Decat turbo back 3” bore exhaust system
Tubular exhaust headers and flow matched uppipe
Walbro 255 l/hr uprated fuel pump
K+N panel filter

Level 3 Power may shorten the life of the transmission system this will depend on use and driving style. The 01 onwards UK 5 speeds do currently seem to be coping well with this level of output although as mileage increases this may become more of an issue.

Full Decat turbo back 3” bore exhaust system
Tubular exhaust headers and flow matched uppipe

Note We do not recommended level 4-5 on standard internals, clutch or gearbox. As a mimium we recommend forged pistons
and steel rods, steel head gaskets, uprated clutch. We also recommend either a PPG gear kit or 6 speed gearbox conversion ( from later STI)

thanks that's a lot easier for me.

1 or 2 looks good to me

Don't worry mate - we look after new members - there are no nasty people on here.

Has your car ever been remapped before or is it totally untouched? This makes a big difference as you will need to pay for an EcuTEK license on top of the mapping cost charged by the mapper. The license is a one time only charge. Subsequent remaps from the same mapper will cost about £200 ish. I am not sure how much exactly an EcuTEK license is but I think it's around £400. If your car has been remapped before then it will already have a license and the mapping will cost around £300 ish

going by how the car is at the moment it I say not but im only going on my last car how it felt.

how would you find out if it had

Have you not got any paperwork, invoices from previous owner? Might be a dyno graph printout or did the sales advert mention anything about it being tuned? Did the sales advert just list the standard power for the 03 WRX? That's all I can think of - the more techie people on here may be able to tell you more - I am at my limit of mapping knowledge mate
