Guys iv pretty much got my car looking sweet mechanical and visual, next im after some engine mods that are pre remap friendly, so far i got magnex backbox and k&n panel filter!

Please can someone say what else to do before spending hundreds on a remap!

God bless rs days buy a turbo stick it on, buy induction kit stick it on!!!!

 

How much you are looking spend?

Decatted exhaust will be needed for extra bhp(at least decatted downpipe and STi up pipe)

3-port boost solenoid(this will fit mapper)

Walbro pump as you are suggest

Panel filter you have

And you should be have around 270-280bhp

So a decat, 3 port boost solonoid, and pump can be done without remapping????

 

No for these mods you will need remap,without the remap you can put only Fuel pump,decatted downpipe and center pipe.

If you want extra BHP,remap will be required.Running un-mapped 3-port boost solenoid will cause more problems,due this i would put 3port before remap or on mapping day.

Oh ok mate, can you send link to a good centre pipe and decatted down pipe and good place for fuel pump!

In time i will get a remap but just building up to it!

Thanks for your help!

 

Cobra Exhaust UK have good prices for decatted downpipe and center pipe

i wouldnt fit a straight through exhaust with out a map,if i was you id collect all the bits you want untill you can afford to map it then do it all in 1 go its the safest way! also walbro pumps arent recomended anymore rcm do a good 1 but its twice the price... you get what you pay for.

 

i find it strange that some people all of a sudden are reporting their walbro 255lph developed issues once they were a few years old as they found then they didnt cope with fuel delivery past 1.5 bar boost and were leaning out.???

 

New age ECU is different from older classic ECU and New Age ECU will be OK with decatted exhaust and fuel pump...

Who told you Walbro pump are not recommended anymore?
Walbro are most used and RCM is just re-badge'd Walbro with stamp of RCM.

hi jura,
i read on a different forum recently a post from a respected engine tuner ,he said allegedly " Bob rawle has seen this more frequently on the older fitted pumps as past 1.5 bar on a map the fuelling went out the window"?? obviously i have only read this and i for one wont be replacing my two year old walbro anytime soon

 

Agreed older Walbro fuel pump will fail,but don't think 2 year fuel pump will fail after raising boost to 1.5bar...

Older car or new age impreza has have as standard 190lph and some are old 10-15 years.


Jura

 

the newer walbro,s have problems also,as i was going to have 1fitted last week but bob said no only an rcm 1! and there not just walbro,s with an rcm name!


didnt realsie it was a new age

 

I was run "cheap" ebay walbro on 350bhp without the problem few months and i'm using HRC fuel pump 340lph on 500bhp.


Jura

 

i believe boost above 1.5 bar was the issue but till i hear that from Bob himself im choosing to keep mine for a few years longer !!!
want Bob to ecutek mine but thats next year so ill see then

 

i think newage have a oscilating fuel pump voltage 8-12v ,???is that correct ??

 

This will help,this is test of fuel pumps in USA.
