hi everyone at the moment i drive an integra type r want to change to rwd or 4wd turbo jap import but am getting worried about all sorts mainly will irish fuel mess up my engine does a remap work and is it worth it cars im thinking off are r34 impreza sti s14 s15 r33gts are these going to break my heart isee other people with them so it has to be possable

Every one i know who has a jap turbo car (myself included) has not had any isseus with fuel. With the octane difference all that happens is a small loss in power. Its not bad for the car and your car will run fine. The actual turbo reliability depends on the type of car and how hard you drive it.

With a fresh import, you'd be mad not to get it remapped to 95 octane, eventually it will do damage to your engine, i know of numerous impreza's ect that have detonated because they did not get a remap!!!

regarding a remap, It depends on the setup. If the ECU is standard it should be able to adjust to the slightly lower octane rating for Irish fuel. The ECU will adjust the fuel/air ratio appropiately(I think). If you notice the car does not handle Irish fuel well a remap would be best. This may be needed if he ECU was changed to an aftermarket one. The best bet would be to call up places that do remaps. Firstly you should get the car dyno tested to see if there is a loss in power, and it would also give the guys an idea if a remap is needed to improve engine life.

Alternativerly, you can use an octane additative to increase the octane rating of your fuel every time you fill up. If the car is a daily driver though this will be a pain and also be expensive.


As for reliabiliy, it depends on each car, its mileage, service history and how it has been driven. Things such as a turbo timer, ensuring the engine stays running after you shut down the car to allow the turbo to cool will increase reliability. Just ensure any mods on the engine are correctly carried out and you should be ok. Each of the models above have different charactistics, so you best bet is to ask on specialist sites for each.

The cars you mentioned won't break your heart once you look after them, with turbo cars its especialy important to let the car warm up and cool down to lengthen turbo life. Starting the car 5 mins before you drive off in the morning and leaving it tick over, and doing the same when you return home(or fitting a turbo timer as above) should really help. It may sound a bit excessive but many of the owners of these cars do it. Also a service history of the car since its been in the country would be good. Regular oil changes essential for turbo cars.

Hope that helps!:)

sound lads all i need now is the money lol

Octane boost is ridiculously expensive stuff too. Apparently you can use something called toluene which is like paint stripper and it does the same job. WAY cheaper but hard to get here.

no its not, jap turbo cars are ok on irish petrol if its a glanza or GT turbo, NOT a 4wd car like an Evo ot STi impreza FULLSTOP.

sorry for my harsh words but you will need a remap for irish petrol, the standard ecu in an impreza will not retard enough for 95 ron petrol and you WILL blow your engine within the year.

theres a few option, including an apexi power FC, Ecutek remap to name but a few.

the problem is not the power loss, but the detonation due to the lower octane fuel and boosters simply just dont work.

have a look over on http://www.dtdirl.com/forums/index.php to get some ideas on what the best option for that particular car you get.

i drive an Evo 5 so i know what the best options for the evo's are so contact me if you need to discuss further!

I've heard that the impreza's don't handle 95 well at all, im not sure about the other 2 but either way they'll all bound to suffer from a certain amount of knocking so the first thing id get done is a full remap. I wouldn't buy one in this country from someone who hasn't bothered to get it done either.

Ever hear of detonation, not good for your car at all.

Anything i've ever read on these said they made flock all difference. If your going out and spending your head earned money on a car, I wouldn't be trusting this stuff to keep it protected.

I have an impreza i bought a few weeks ago, id like to get it remapped but dont have the money right now. At the same time i was talking to a guy in westfield engineering which i have been told by several people including performance car mechanics that they are the best people to get a remap done, anyway the guy said its not really worth getting done and the engine will be ok if its running on standered boost.

Im not sure about this, sometimes when im accelerating there is a loss of power, i think this is from knocking though im guessing really. Most octane boosters are supposed to be very bad, silkolene pro boost is supposed to be one ofthe best, its 30 euro for a litre, you can use between 500 ml and 1.5L to 50L of petrol and each 500ml will raise the Ron level by 1. Im putting half a tin into each tank of petrol, does seem to make a big defference though i changed the oil, oil filter and air filter at hte same time as starting to use it so its hard to tell.

You can get it in a place in blanchardstown called proparts and also in a place in stillorgan near the shopping center im not sure exactly where.

In terms of hte economy of a remap though an fc power ecu is about 700 euro, more like `900 if you get it in ireland, then a remap will cost about 300 depending on how you want it mapped. so say 1200 euro, silkolene pro boost at 15 euro per tank of petrol is cheap in comparison.
