right im in a right muddle here. my 95 wrx has a 93 engine and i thought a supposed 93 ecu too. the ecu in my car is a "u8" one and i thought this was rated at 240ps, but after seeing this thread http://https://www.scoobynet.com/cla...e-t539318.html where jim.cooper has a 94 sti ecu for sale (also a u8 one) im now in much doubt as to what the power output of my car is!! didnt 94 stis have 250-260ps standard?

ive never driven another turbo scoob so have nothing to compare. could someone please clear this up for me as i havent had chance to do a rolling road, plus ive got a full 2.5" decat system on her now and shes fekin fast in my eyes lol.

any info or facts/figures/stats etc would be great... does my car have a sti ecu??? or was the same ecu used for different models?

Hi mate, i own an 94 Sti and the ecu's there use are SA pink bagde type and the 94 STi-RA use SB types both have an aggressive boost/fuel map and SA/SB boosts to 1.1bar (mine does with only a de-cat) (U8 are 0.8bar). Im not sure if STi ecu's would blow an WRX engine after long term use though. There's sum clever guys on here who would be more help.

only a cosmetic thing mate but when i got the car it came wih the original pink 6 star badge too, although i suppose this could have been altered. also on the side of the nearside passenger door i recently noticed while waxing and polishing, score marks to suggest graphics were once there... spelling out... you got it... sti lol.

il be getting her serviced soon enough by a subaru specialist so i will ask whoever does it for me to try find out, incase something is a miss...

I'm pretty sure STI badges weren't put on the side on the doors ( i could be wrong).
The first model STI was just a modified wrx so could possibly use the same ecu with a few tweaks.
Even taking it onto a RR doesn't prove anything had my 93wrx with just a decat/IK and made 250bhp yet another one (same model same mods)only made 220bhp.
Best thing to do get a z4 ecu, just fitted one and goes like stink.

if i had a better camera i would show you proof of the score marks. they clearly spell out sti on the n/s rear door (doubt that they were standard however, probably previous owner put them on the took them off)... the mrs noticed it not me... and there is a u8 ecu here http://cgi.ebay.co.uk/SUBARU-IMPREZA...QQcmdZViewItem which a guy has a u8 ecu for sale from a 92 impreza...

im looking at a remap eventually anyway, as ive got a full decat too and yep, she goes like stink. wish i ad another scoob to compare acceleration so i could maybe get to the bottom of this...

There were 4 ecus used in the first WRXs (u8 and w6 can't remember the other 2 were all rated at 240ps with the same boost levels) cos i've got both at home both taken from 93/94 wrxs.
The easiest way to get a remap is the Apexi power fc (£750 approx) uprate fuel pump (£95) late model TMIC and possibly do the injectors.

ooof, what sort of power would i be looking at then? all i was looking at doing was going to scoobyclinic and getting one of their "simple" remaps, so i dont have to upgrade loads of parts. i just want my car a little faster and somewhere round the 280-300bhp mark. im led to believe that upto a power output of around that, i shouldnt have to upgrade anything really?

Over 300bhp ( but it depends when you get it remapped my mate had his Apexi mapped in winter still had standard fuel pump and injectors made 310bhp but in the summer the injectors started hitting 98% not good and had to remapped and only made 270bhp).
Even if you don't get a remappable ECU change the brakes (if you still have 2 pots) cos they are ****e great going fast but i find it better to stop quicker

i know that mate. looing at some different discs and pads, mine are very worn but im not in the money league to get a big brake conversion as of yet!! plus my car is old so wont really have a sell on value either so more subtle removable mods...

myblackwrx

4 pots from a late model will set you back about £250 possibly with discs just bought a set for 93 wrx

are they 295mm brakes? whats about the rears????

myblackwrx

iTrader: (1)

As far as i know yes (haven't had mine fitted yet) don't worry about changing the rears just uprate the pads( even the discs if you're feeling flush).
Uprate the hoses (at the front) and fluid and the braking is so much better (although not done to my car yet i've driven one with the improvements and damn its so much better)

chocolate_o_brian

iTrader: (22)

what if i upgrade the normal discs and pads, or is it really the 4 pots i need for better braking? i was looking at some grooved but not drilled discs and then decent pads, but not redstuff, theyre ****ty in the cold. ive got rear vented on mine now 266mm so decent pads will be fine for that, but its the front that needs operating on.

ok so in simple terms, what would i need to buy regarding upgrading from 2 posts to 4 pots... calipers and discs/pads. and how do i replace them when warn, as they are none standard. would i go by the year of car they came off???

myblackwrx

iTrader: (1)

Buy a set of 4 pots of any classic (you have to have 16" wheels minimum) and they should fit with regards to discs/pads you're right go by what cay they were taken off.
Best to buy grooved as you said, pads mintex 1144s good but squeal badly Ferodo are highly rated.

i have a horrible feeling they wouldnt. ive got speedline st2 wheels on at the moment... 16s and 277mm brakes/2 pot calipers and this is how close they are to the inner of the rim...

myblackwrx

iTrader: (1)

Looks like you have a bit of space to play with the STIs have 16" wheels and 4 pots.
I'm having mine fitted in the next week or so so i'll get some piccies up ( the guy who sold me the brakes had 16" Volks fitted)

chocolate_o_brian

iTrader: (22)

maybe. i cant really find any 4pots anywhere. looked on here and ebay... i only need two really for the front and then some decent discs and pads... well even if the discs and pads came with that would be good....

API sell them for £300 (www.apiengines.com)
Glenburgie worth a look (www.glenburgie-subaru.co.uk)
Grade a subaru (www.gradea-subaru.co.uk) they sell them as a kit with new pads and discs but not too sure on their pricing.

Like i said i'll hopefully have some piccies in a week or two
