....we all make misstakes , the petrol we have here , smells more like paint stripper and actone ,and has no lead , and you have to keep an eye on hoses that they havent melted....with the advance , the idle has to be lowered but the main one is the crank sprocket triggers and the number one cam triggers are in the right position so the computer thinks nothing has changed , the nock sensor takes care of to much advance and shows that is working ....

just a wee note to update things , I'm still having good fuel savings of just over a third and every things fine

in my country we dont have highoctane fuel , its all crap , my cars running great , there's no nocking or anything , temps good , it good on fuel no no matter how much I stand on it ..I never said I was the top dog here , just if you have nothing to lose , it dosnt hurt to try something , my other car run for years on more advance than my latest one ..the old colin mcrae derek ringer car .....I'm only advancing the crank and not the camshaft , I know the difference ...what Im saying is this stuff can be moded with simple hand tools

one of the problems with electronic ignition systems is there is no way to adjust the timing to make up for poor feul quality ....and with old school , if you have highoctane fuel , you retard the timing and with low octane fuel you advance the timing ...but we dont have the same fuel as in Japan , what we have is not real fuel , its a cheap copy made to hit eveyone in the pocket $$$ and with ignition timing set for good fuel , our cars will only drink more to make up the power loss and give you very poor miles per gallon or klms per litre.....

I can make my own pins and theres no point buying anything when the pin hole can be moved easy with a chainsaw file

ok I will keep everyone informed on my engine and how long it lasts for ...I have a spare cam sprocket that I'm retarding the camshaft key to keep the cam timing close to original spec as possible....and it too! is made from mild steel and can be filed by hand

my car drove like a pice of crap befor I changed the timing , so its hard to tell , if I lost any top end , and with changing the exhaust to that of a 1991 and repacing a faulty air meter 22680 AA160 , top end is still there , its just quicker to get there , and harder to keep at the speed limit with it wanting to go and go

my car still has all its standard exhaust setup from behind the engine , so it should read less poluting carbon emitions with a improved flame speed in the combustion chambers ...the car gets off its arse without heaps of throtle down low and uptop

I put a new cambelt in for the quad cam engine at the same time , so the cams are set correct ...only changing the ignition timing

yes thats the idear , so the ecu still thinks nothing has happened , but the ignition timing is advanced to your setup

hi , I have found a simple way to increase the performance of the 250t and all other subarus , the crank cam belt timing sprocket is only made from mild steel and you can re-cut the keyway slot with a flat file to your advanced spec for your fuel ...and weld a blob on the key with a mig welder and file to suit and ovoid contact with the generator pullys and there you have it , instant horspower gains and improve fuel economy , yes you will have to lower the engine idle , I'm very happy to pass any help to those who need any help ...just be carfull filling , 2.5 mm to 3.5 mm max ...mines set at 2.5 mm advance get a spare sprocket and modify that one so you still have the orignal ...and reset your ecu and happy motoring
