Hay guys just got one of these ecu units and a TD05 for my uk but wanted to know do i really need to get 440cc injectours for 330bhp or can i use the one's already in the car?

Trying to keep cost down as its already at the £1000 mark!!!

2nd hand set of 440cc or 550cc (about £300) as you can run bigger injectors at lower duty.

you could always get a pressure regulator and run a higher pressure, however you would be better upgrading the injectors. If you check out Jollygreenmonsters website, I am sure he sells some higher spec injectors for a reasonable price. He also maps the apexi as well

I was told by the guys in the know that I would have to uprate injectors to break the 320 mark, was told to uprate the pump to a walbro even if I don't change injectors.

Trouble is second hand injectors are always a gamble and new ones aren't cheap.

I would recommend a Walbro on all classics and a TD05 will max 440's even with raised fuel pressure.

So are you saying i need 550's???

Yes 550s would be ideal.. 440s run to about 320 depending on whose rollers.. upping the fuel pressure will allow a little more. . but price of 440s + regulator (a decent one) you may as well just do 550s.

As said it is worth fitted a walbro fuel pump.. just for piece of mind and because they don't cost the earth.

I'm at 325 bhp and my 550s are at 73% duty IIRC. I could be wrong, but would assume this converts to 440s in the 90's% region. Not much to play with.

£1k really isnt very much in the world of Subaru tuning

monkeysan

was going to say - i've spent double that just on pissy little bits and havent even started on power!

defo go for 550's - would much rather have injectors running at lower duty cycle

You lot are rich thats why it aint much

I have 2 other cars and a wife and 2 kids to feed!

The subaru is just some weeknd fun and tell her im spending 2-3G on it is not going down to well!

But thanks guys for the help it looks like 550 it is!

For the projected 330 hp your after a decent top mount will be fine......

sc00bylee

Im using 89% duty cycle on 550's with a TD05 on standard fuel pressure.
would defo go for 550's

You will need 440cc + uprated Pressure for 330BHP (at least).
And also consider a larger TMIC or a FMIC as the standard ones get a bit inefficient above 300BHP.

If your car is a pre facelift then you already have a TD05 on it and defo need an intercooler to replace the slanty one..

Got this...


And some 550cc for £100!

Also got a fule pump on the way from ebay!

Off to barbados now but will see you when i get back for the remap simon!

P.s. Any ideas on a fitter for the injectors, TD05 turbo and the fuel pump in london?

P.P.s how save is it to drive the car for a few days with all this stuff on before i get the map done?

Barbados!! alright for some

I can organise the workshop I map out of near Maidstone to fit the parts and map it from there if that helps?

Thanks
