Hi all checking my oil tonight and noticed my car has yellow injectors fitted what size are these mine is a 99 uk turbo are these the correct ones i gather different colours are the sizes but correct me if im wrong cheers

 

440cc
Standard for your car.

 

Brill thanks whats a sensible size to go upto its making 279 bhp at the min just looking at further mods

 

Depends what final power your looking at,decide that and you can get a more comprehensive answer.SJ.

 

Hi i would like 300 to 320 if poss what mods would i be looking at im in the dark a bit really dont know whats been done and what hasnt i know it has a sti intercooler thats about all i know im going to be uprating the fuel pump nxt but dont know where to go from there i was looking at sti inlet manifolds but dont know if there any different from standard ie throttle bodies and bore etc aby pointers suggestions would be great

 

You can see those bhp figures on 440cc injectors.SJ.

 

Thanks for that what about the sti manifold worthwhile or not

 

only if you prefer the RED hue.........................


an STi manifold is identical to yours

 

Ha ha brill save a few quid thanks

 

For around 330 ish . Get your ecu updraded with ecutek, remapped, turbo from an sti - i reccomend a vf23, upgraded fuel pump, exhaust and air filter.

 

Your 440s are good enought for 320bhp but your car will have a tdo4 turbo, good turbo but your wont see much more than 285bhp, you should upgrade this next. Vf23 is ok but but are all getting old, you would be better off buying a vf34/35 from a newage sti. Fit directly to your car. Your sti topmount will be good enough for 320bhp. I would suggest a shopping list for 320bhp ( if you havent got these)a K&N panel filter, silicon inlet pipe, silicon y intercooler pipe. 255ltr fuel pump either walbro or hrc. Ngk 7bs plugs. Decat downpipe and centre ,Vf35 turbo and a remap.

 

But if your going for power make sure you can stop. You should have the subaru 4pots. They are ok but I would suggest a decent pad and disk setup. For peace of mind I would look into some newage brembos or ksport upgrade

 

Yeh i have subaru 4 pots and i think there crap tbh brembos were on my shopping list ive just come from a porsche 911 carrera and the brembos on that were superb touch the pedal abnd your eyes popped out

 

The subaru 4 pots are ok. But they probably need a rebuild as the pistons seize. So rebuilt with quality pads and discs should be fine at that level.

 

Yes your right i was looking at getting them rebuilt its had new discs and pads fitted just before i got it but the brakes feel very wooden to me and i know 1 caliper is deffo sticking the guy did give me a new seal kit when i picked the car up i will be getting some stainless pistons aswell i think

 

imo it's worthwhile doing a full rebuild as I've had it done on my calipers

Stainless steel pistons
New seals
Godspeed grooved discs and kevlar pads
Uprated brake hoses
Good quality brake fluid.

Stops my car a treat (only a 300bhp Type R) but the work very well on spirited B road drives

 

Yes i think i will it has new pagid grooved discs fitted so i think i will try decent pads and get the calipers rebuilt and maybe some braided hoses
