Depends what kind of jap import it is, if it's a Hiace you might be alright.

BLACK V5

It should run on 100-102 ron. So no not good. Atleast sul or optimax & octane booster is best unless its remapped. Car will be well down on power on 95 & not very good for the engine at all.

Hiace Turbo!

What kinda booster do you recommend?

BLACK V5

Alot of people say NF. Never tried it think you have to measure out so much per tank. I use millers. Just chuck the whole bottle in then fill up.

Melted piston is never nice...

I ran mine on it for 3 months when I first bought it as I didnt know any different, until I found scoobynet. Hasnt shown any the worse for it and the first 3 months are always the hardest when you get a different car

Not that I'd recommend it though

gerryirl

it s a mate of mine has a type r.. is this the same for all jap imports then.. can it really screw up your pistons

Its more likely to destroy the big-end bearings than hole a piston. Running any JDM Impreza on 95RON fuel is foolish, in fact its stupid.

Depends how old the scooby is as to how bad it is....if it's an old 240ps then things may not be so bad...but if its a 280ps, well as above - not clever at all!

If you were to talk to any of the specialist companies who advertise on here such as API, Powerstation, Scoobyclinic etc, I'm sure that they could tell you that 9 out of 10 engine rebuilds they have to do are from jap import cars run on incorrect fuel, eg 95 ron.

GC8

I agree, but its a Type-R..... When the 'A' series Impreza WRXs were produced Japan didnt have 100RON fuel. I still wouldnt chance 95RON though...

Ahh didn't see the type-R bit.

Tell your mate to get it remapped for UK fuel if he intends to use 95ron. Otherwise in the long run it will hammer the big ends, and may melt a piston on a good blast down the lanes or motorway.

Dave makes good money out of peeps who do not bother remapping their imports for UK fuel. Or take other precautions (97ron+ booster +cocklink ).

It 'll only slow you down a little bit, if it doesnt go bang.

man you're a ********, ive been reading some threads with u and all ur replies are negative crap!
what if u havent got a choice?? i live in southern ireland and we aint got nothin but 95ron! there might be one or two places in the country still selling 97 sul.. 5 of my friends run sti's, wrx's, and 22b on 95 ron and with no mapping or aftermarket ecu's! some of them dont even use booster and they still runnin strong all these years!the later scoobs will automatically retard the timing if it senses a knock, earlier models are fine on 95..one of my best friends has a 95 wrx import with 195,000 kms on it! and its runnin grand, never rebuild or anything, and he uses 95 with no booster. this is the most negative damn site ive come across

me again - glad to see your still as fookin stoopid as you ever were

@flat 4 where in Ireland are you.. i'm in Roscommon.. no 98 petrol up here at all .. all the japs are run on 95 here . I think there is a place in clane that do remaps for 95

flat4_ire

ah not you again, im just giving facts man, obviously runnin on 97 is goin to be better for her..im just giving the results from what ive seen so far lad..maybe if u stop bouncing ur scoobies off the limiter ya wont be going through 2 engines a yr

flat4_ire

well man, im in carlow, 95 it is, i use NF Race aswell, seems ok stuff, i have an apexi power fc here waiting to be mapped, i wudnt trust too many lads over here to do it, westward engineering in enfield,co meath do it i think, and trackday performance(**** them tho)

gerryirl

@flat 4... where in ireland are you... i'm in Roscommon... no 98petrol round here either just the 95 stuff.. all the jap imports around here are on the 95

gerryirl

sorry about the double post .. ya I think the remap seems a good job.. how much will it set you back

flat4_ire

got the apexi power fc with commander for €800 delivered from japan which is very good, will cost me 200 sterling or so to get the car mapped then, not too bad i guess considering

gerryirl

sorry for askin a dumb question i'm new to all this stuff .. what doea the power fc do.. is it for fuel an boost an all that

flat4_ire

its a replacement ecu for your standard one, it can be mapped to run on any fuel u want, ignition timing etc, i havent got any experience of using aftermarket ecus and this will be the first, hopefully itl b a good job, what scoob u got

gerryirl

can you just get the remap without the power fc... don't have impreza I'm afraid would love a typre r .. the girlfriends brother bought one a few weeks back an I love it but I do alot of drivin so as you know a typre r an the price of petrol over here ain't good.. I'm a toyota man myself have had a couple of celicas. have one at the minute but would like the impreza.. maybe next year i'll be working nearer home so maybe then i'll be in a position to get one then

flat4_ire

the newer scoobs have different ecu which can be remapped, versions 1-4 need an aftermarket ecu unfortunately, i import myself, sold a few starlets and celica ss3's, gt4 is a nice job
