7AFTE, Check out page 3, one last question before the car goes to the shop Options

quick question about the 7afte, oil all around your turbo isnt a good thing or is tht normal?

[trd94]

most of my hp figures are on motor, and DD is Daily Driven.

no it is not normal, did you install the oil reducers to help limit the oil pressure to the turbo if not then i would say you just blew yous seals. also make sure your return line does not have any sharp turns and is at least 1/2in if you are trying to run 3/8 you well be choking the turbo . atleast that is what mine did with the 3/8 line, i run 1/2 now and no problems ,no smoke , no oil loss.

[pabel89]

idk why all that oil was in the turbo, i clean it up and ran for about 30 mins no oil , i just got my car back from my mechanic, mayb they move something idk but its not happenin again after i ran it.

[mikecelica]

got your car back from the mechanic? as in already problems are beggining with the 7afte? Plus dont you think 10psi DD is a bit too much for these motors?

Plus i was wondering can i use the stock oil pan from a 3sgte thats turbo ready? Would it fit easy?

i dont think the 3s will bolt up to a 7a, differant motor family and 10 psi would be ok to run on a DD if it is tune good. i run mine at 10-12psi DD but i dont beat on her at every light and it only had 55,000 on her at the start of being turbo. now it is at 97,000 and ran for three years with me learning with this setup .... i think if i knew what i know now 3 years ago i would not of been worried about my rings

[trd94]

the only reason i am did the rings and bearings is i have the motor up & out getting the head done to help with flow, and i had a set of bearing made for me in japan when i was there for work. now i should not worry about the bottom , as far as that goes, still cant put to much on the stock rods and pistons.

I got about 105 miles on mine.. thing is i work at a toyota dealership (nothing mechanic related) just driving shuttle, picking up parts stuff like that..anyways i asked the mechanics and they all say the 7afe will not handle boost and say your gona blow your engine.. One of them actualy done it on a corolla and blew the motor at 12lbs i think... Plus what i meant was the 4agze oil pan sorry. Could i not take it off the mr2 and use it instead? We got an mr2 supercharged at work everyone uses for parts. thanks for the help

well i can prove that the 7a well handle 17 psi , but can it take it all the time. no not with out a little help in the bottom and at a good tune 12 psi is do able . if you do the research you will find out that most motors blow not because of the turbo but because of the tune ,and the lack of doing it right the first time. i have guys at the track tell me all the time i am going to blow my motor and at the shops around here they say it cant be running with turbo, but for three years now they have been wrong. if the pan will match up with you bottom and is not to deep ,clears everything then it could work. ... if i remember correctly i think it may be to deep and wont work with your oil pump also at 105,000 i would check compression and do a timing belt ,replace any seals that leak or looks like they may leak, also do a tranny filter change if you are auto , and flush the cooling system and check for any leaks. the turbo well put more stress on your cooling system as it adds more heat in the cylinders.

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?

[mikecelica]

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

[mikecelica]

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

[trd94]

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.
