right am looking for more power so some upgrading needed

car spec so far

wrx sti 1994
fmic
td05 16g
255 fuel pump
3" exhaust fully decatted turbo back
high flow oil pump
k7n induction
standard boost

currently running 331.8 bhp (fact) as been dynoed . i no it keeps getting undermined but it is what it is i was also surprised will try and put graph up but havent a photo yet.


plans

td05 18g
v3-4 inlet manifold
injectors
maybe fpr
esl live map

right basically the question is what cc injectors will i need for this and any1 got any?also will i need a fpr and any other mods. with all this what sort of bhp - torgue should i be looking at.

p.s was going to get racedynamix to do the esl map, any input would be greatly apreciated.

440's at a minimum, but, 550's will give you more headroom, IMO.

If you're going to get an FPR don't skimp on a cheap Ebay item, get a decent one, Fuelab, SX etc.

Mines been running 330bhp with 380cc injectors for 3 years on a standard ECU now.

Just noticed the 18g bit, 550's at a minimum IMO.

 

If you are going the adjustable FPR route then make sure you get a gauge with it. It means you can set the fuel pressure up right so only one variable is changing at a time. 550's will be fine.

Also be worth checking all coil packs are in good order before mapping as they have a distinct habit of cracking and spoiling the fun. New plugs would be good too. (NGK 7's)

Power wise, it really depends on what it is happy/safe at and how well things like your FMIC are working. The 18G should be happy enough doing 350-360 though (whether your gearbox will like this is a harder question)

 

No mention of changing air flow meter or map sensor ???

 

ESL boards now run mafless Andy but yea changing to a later model map sensor is a def worthwhile mod

 

I did not know this, awesome !

 

dont change your inlet manifold,ive been told the v1 manifold is the best for torque

 

It is optional but yes they can be mafless.

 

im new to tuning subarus, so bear with me.the figure of 330 you say you have would be perect for what i need.

yours is a sti engine tho where as mine is only wrx, but i have sti ecu (z4) fmic, induction kit,stainless,poss decat, and you say your running standard boost?

1. what differences are there between wrx and sti? pistons?

2. what is a sti ecus standard boost? what is yours?

3. how many cats are on these?


ive not had the chance to check it out underneath yet u c.

sorry to myther u guys.................

I know, thats why I said MAF -OR- MAP sensor, std map sensor would be no good on an ESL with a bigger turbo.

 

is the mafless esl a new board or a software up grade?
