As above i have a 1995 WRX import,

have a few mods, but am going to fit a few more then go for a remap, but think with these mods i understand i could raise the boost a bit. was thinking no more than 1.5 bar

the mods are
hybrid FMIC
standard td05 16g
440cc injectors
warlboro
tubular headers
3" turbo back exhaust with sports cat.
fuel press reg (if needed??)
HKS F-CONS ecu

now i understand my (map sensor?) is limited to 0.89 bar of boost. if i fit a later one i.e a 1999 one can i then raise the boost to 1.5?
or do i need to get a seperate boost controller and the 1999 map sensor?

i dont fully understand what a map sensor is, and if it controls the boost, or if i need to buy a seperate controller before the remap?

can anyone shed a bit of light on the above, as im a little confused

Your map sensor will limit max boost to about 1.2bar (standard ecu for a 95 wrx is running just under 0.9 bar).

ok cool,

if i take a map sensor off a 1999 sti, do i also need a boost controller to raise the boost.

can anyone reccommend a good one? dont want to spends loads, but also dont want an absolute rubbish ebay jobbie

well you can raise the boost with the ecu when it gets remapped.

Greddy Profec SpecB II
Apexi AVCR (think this is very popular)
Harvey does Hybrid boost controllers (he posts on here as Harvey or he has his advert on scoobynet) these are only about £100ish

i think you've asked this question before haven't you

hi, just wasnt sure if that could be done with my hks f cons

but if it can, ill just get a later map sensor and get it raised on the remap

Didn't you say Regal were going to do it i always thought they strictly a Vauxhall tuner?

regal never got back to me, but Geff from reworx.com in portsmouth can remap hks f cons

just had a look at their site and they do mazda rx7's but said he could do the imp so guessing its pretty similar

I guess you looked at this list HKS European Dealers

Re worx are very good with Rx7s my mate has a hill climb RX7 mapped by them (well last time i saw him which was a couple of years ago now)

Are you on standard internals? Pistons will turn to mush pretty soon running that boost, if the head gaskets don't fail first. Don't want to sound negative but you need a sound bottom end before anything else.

hmmm.. ok what sort of boost do you reckon would be safe runnig through standard internals?

a guy off here reccommeneded around 1.5 would be around the limits of safe

1.1-1.2bar.
1.5 bar is normally the limit of a td05 turbo.

Don't forget thought the extra stress put on the gearbox and clutch

ok great reckon ill go for a safe 1.2 bar then with 440cc injectors

and i mailed geff and hes gona look into the software whether the f con s can be remapped to raise boost aswel.

Question with 440cc injectors and the above mods, am i gona need a FPR or will i get away without? and would a £30 ebay jobbie be okay, and what would i want pressure set at
