hi any idea what my next step is to get 320bhp these are the mods so far???thanks.........ive got an uprated fuel pump fmic yellow injectors which i think are the upgraded ones not sure tho also got a full decat an induction kit hks blow off valve a tdo5 16g an uprated headers i think and im running 285 i have an old rr print out ov it at 291 but dont no why its lost abit ov hp,not sure what ecu ive got coz i aint had time to have a look yet but i was told that a live remap would get me to 320bhp any advice welcome

 

What model Subaru is it?

 

its a late 94 classic wrx mate

 

Need to add:-

550s... FMIC... big cone filter... NGK PFR7B plugs... uprated MAP sensor... remap... for <=350bhp.

Will need ESL Live (now MAFless! )... or the similarly MAFless Simtek (plus dual full maps ) as your mappable ECU option...

 

he beat me to it....

 

...by a few seconds!

 

lol..thanks for the help..where to i get a better map sensor from?and how much are they?also i thought the yellow injectors were 550s?thanks

 

MAP sensor can be obtained form a MY97/98 or MY99/00 car that's being broken. I'd go for the one off the MY99/00 as it offers a higher boost cut target (so may future proof you better for a higher boost target later on, should you need it).

The OEM Subaru yellows are 440s - they should see you to 330-340... but might not. Best to go for 550s and be done with it lol.

The Nismo yellows (and possibly other brands too?) could be 550s... but could equally be 440s too.

 

The only way you can determine for sure what they are is to pull them out and post some pics and some of the lot on here may be able to help.

You may also get away with increasing the static fuel pressure to them by using an uprated FPR to give you that extra head room (this will be mapper dependent, as i know some mappers rather go the uprated injector route).

You need to find out what ECU you have, as the standard ECU in its standard form will not run 440CC injectors.

 

yeah i looked at the ecu and its got prova on it,is this a standard ecu??

 

im thinking ov getting a esl board and having it remaped at the mo to get more power and more boost out ov it but dont no if this is the best thing to do next?lol

 

Nope not standard>>>

I'd personally get all those mentioned mods first and get them all fitted and remapped together on the MAFless ESL Live, so as to get the optimum bhp/torque/drivabilty from your 16g.

Otherwise, you'll only want to do it sooner or later, further down the line...!!

 

I would certainly do that if i was you, as the PRova ecus are 98 Ron + ECU's and perform at their best at 100 octane which we do not have. They also run a few more degrees of ignition advance than the prodrives as far as i know.

I would definitely say speak to a mapper local to you who is competent with SUbaru mapping and tell him what your after and see what he advises....as remember it will be him/her you will be relying upon in the end.

 

Lol....a few seconds in it again huh....

 

thanks for all the advice its been very usefuil im now going to go find a decent maper and speak with them,cheers

 

Race Dynamics ("dynamix" on here) is mobile and is based in East Anglia.

"Jolly Green Monster" is another 'mobiler' and based a bit futher away in Kent.

Won't go wrong with either....
