hey guys,
i have my first impreza on the way from japan, pickin her up in 4 wks..its a 98 type R V4..grade 4, mint cond...anyway, im wondering exactly, what fuel do u use? 97 super unleaded is the best u can get here in ireland and thats hard enuf to find..i heard a few bad stories bout using octano booster in the long run etc..a friend or two have stis and run them on 95 with octane booster..its prob run on 100 or 102 in japan, so im wondering will it be grand me runnin her on 97 or wud u reccomend gettin it on the rollin road and the timing done to suit 97?
help wud be appreciated lads cheerS!!! any good or bad points experienced with ur stis feel free to mention aswell

use optimax + octane booster (millers,NF Race etc) until you can get a replacement remappable ecu.Also recommend investing in a knocklink to monitor for Det

fine choice by the way

flat4_ire

yeah il get a knocklink alright, i dont know of any scooby specialists in ireland..plenty in england,poor aul paddies left in the cold again! il give the 97 and millers a lash then and get an apexi ecu end of the summer

HOUSEQUAKE

Splash out on a remap and get the ignition altered to run on Optimax only

flat4_ire

optimax?? aint got there here in ireland, texacos 97 SUL is the best, that will have to do, can the standard ecu in the type r be remapped?

Iwan

If it's an STI5 Type R (MY99) then yes the standard ECU can be remapped (Tek3). I think everything older than MY99 needs a new ECU, but then an Apexi Power FC is similar money to a Tek3 - around £750.

flat4_ire

yup thats what i thought, shes july 98 V4, wait a while and get the apexi power fc

flat4_ire

whay exactly shud i expect from getin the apexi power fc? with 97 super unleaded

Iwan

Hard to say, the mapper should be able to increase the boost/fuelling to get more power - it's hard to give an exact figure. The main benefit will be safer running (no det) on 97 octane fuel, and if the mapper's good then it should run much smoother (and maybe more economically) too.

To give you an idea, an STI5 should be around 280bhp standard (on jap fuel). I had a de-cat, K&N cone filter and Tek3 done on mine and it went up to 320bhp. Also that's on Optimax with no det. A decat and Apexi ECU should be somewhere in that region.

lots of it!

flat4_ire

cheers man, yeah suppose that wud probably be a good idea £750 power fc supplied fitted and mapped, not bad is it..il look into that,probably worth the travel over from ireland..no real scooby specialists here that have a rep..shes type r v4...apexi power fc prob the best choice by the looks of it

My STi Type-R V5 is standard apart from a full de-cat and is pushing out 330bhp on 100octane fuel.

I'll second that. Before I went Apexi my V5 made 320bhp with only a decat, not had it on the rollers since but feels pretty samey.

CyprusScooby

Anybody know any places in Scotland that I can get my Scooby re-mapped for optimax?

Also how much does it cost?

There is one guy that springs to mind, PM me for details if you want

flat4_ire

100 octane sounds sweet now alirte, pity 97 is the best we can get here in ireland!

Carefull, you might wake the sleeping PSLewis monster, who will sweep down from his cave and burn us all with his throat mounted flamer kit.

If we get on our knees and start praying now, we might get away with only sacrificing a MAF.

im running an Apexi power fc on my V4 type R along with front mount intercooler,decat,induction kit and only made 285 on the last rolling road day so power does vary considerably.

flat4_ire

jaysus, thought with that gear ud be looking at a mininal 300 anyway?whats the craic with that? apexi power fc, FMIC and decat shud gain nice power?

That was with 98 ron (Optimax) and mikkers octane booster. 97 and booster should be close enough but get the knoclink like every one says. Could save you a lot of hassle.

flat4_ire

where can u buy millers booster online? none of u had any bad experiences with octane booster? a guy here who owns a tuning company said not to use it all the time, muck builds up in the valves after some time..what do yis reckon bout this?
