no i been driving my 7afte for a month or so, no problems yet. i go to my mechanic for my weekly check on my car...check everything is up and running the way it suppose to. what is the percentage of a 7afte blow the engine? let say i have 160k miles on my car, what are the chances the engine will blow?

yeah i thought so too... alot of ppl i know said the same thing about how its not the turbo that makes problems but not getting it tuned properly. BTW do any of you guys have a spare 3s map sensor? Im looking eveywhere for one.. cant spend too mcuh though.

depends on your tune and how much you push it. how healthy the motor was befor turbo, and how well it is taken care of . may last for years, or months. or even just days biggest thing is to make sure you dont get any detenation in the motor and keep everything cool.

check the mr2 boards, i am using the boost sensor for the emanage, so i dont have any expierence with the 3s map

what do you mean by detonation on the motor?

ok i dont want to sound mean but you should of knew what this means if you where even thinking about turboing your car.....detonation is where the gas and air mix gets pushed into the cylinders and ignites before the ignition fires spark to the spark plugs. it does this because of the cylinder chambers have to much heat in them because there is not enough fuel in the air/fuel mix. fuel helps cool the chambers just before it is ignited to burn. this is a very quick answer and i would recomend you doing a search on it there are a lot of good write ups on it on the web

just did a compression test done today and was 192,193,189,189 how's that? are those good #s ?

looks good to me, now i would make sure your timing belt is good and that all your seals are in good shape.

just had a quick question is it the 2nd gen 3sgte or 3rd gen 3sgte map sensor that will direct fit with the 6gc? Plus what year mr2's would have the 3rd gen and 2nd gen 3sgte motor? Im just not 100% sure. thanks

both would work, the 2nd gen map is alot more common over here, so its normally quite a but cheaper, usually a 2nd gen map goes ~70-75$ while a 3rd gen will normally go ~200.
all US mr2T's got 2nd gen 3sgtes.
IIRC JDM 94+ mr2T's got the 3rd gen 3s.

got it thanks/

OK i think im finally done the buying process, ive gathered eveerything i could think of now a quick check to make sure. ppl with 7afte, please check my list for final time before i take my car to the shop if theres ntyhing i am missing. thanks

wideband 02 sensor
make sure those probe injectors will work
get rid of the manual boost controller you control your boost by what size spring you put in the wastegate

remember to gap ur plugs a lil smaller after the turbo,the boost will blow the spark out
