Mods for a 3S-FE

    I have a 3S-FE engine that needs rebuilding. What mods can I perform to gain more power, and is it worth the cost?

    Car is a convertible, and Turbo is out of the question since there is no roof support.

    Should I simply order a JDM and add a cold air intake?

    Thank you in advance for your comments and suggestions, Tripp

    I have done all the mods you suggested, without any significant gain. I am running JDM header with 2.25" exhaust throughout without a cat, and K&N panel filter with a 3" feeder pipe from behind the right headlight. Its all fun, but don't expect much.

    my first motor was a 3sfe and really for the money i don't consider it worth modding. i've also been there, cold air and exhaust and a little timing but that's about it.
    i don't see why a turbo can't go in with convertable. the frame is stiffer because of the no roof. a little suspension work and you should be fine.

    For same amount of HP gain and money for you to mod a 3S-FE you can get a 3S-GE. But for the same amount of HP and money to mod a 3S-GE you can get a 3S-GTE.

    Well, Toyota never built a Celica Convertible. They built the coupe and sent it to American Sunroof Corp (ASC) where it was converted. Believe me, it is the same body as the rest only without the roof support.

    You cannot even open the door when you put a jack under her, and besides, I like the fact that I can just park and turn off the engine. My other car is a Saab 9-5 Aero, and I love it, but the “turbo cool downâ€

    uhhhhhhhhhhh turbo timer? if the time is that annoying..... maybe they dont have those over there ;)

    Over there? :shock: Of course we don’t have Turbo Timers here. Only thing that we have here in South Carolina is the BMW Research and Development Department, which is located at the only BMW Z4 production plant in the world.

    Why on earth would you think that we would have Turbo Timers or any other automotive innovation? :roll:

    Honestly, I really don’t want to put that much stress on the body of this car. I really feel that 200+HP would provide too much stress to the body. To be quite honest with you the car can go from 0 to 60MPH in about 6.5 seconds, which is not bad for a 3S-FE. Of course, the car is very light and much of the area here is actually below sea level, which means that the air is really dense.

    The one thing that seems to slow me is the T-VIS. I can really feel a huge difference when the second valve opens. Perhaps I should just find a way to remove that stupid thing. Anyone know of a way to remove it and what happens when one does?

    Thanks for the comment, dude. The Turbo Timer is a great suggestion, and the sarcasm brought me a good laugh. :lol:

    First i was not aware that the 3sfe had t-vis ....
    Second , my 3sge wont do 0-60 in 6.5 sec i dont think ....
    :roll: whats goin on here ?

    um yeah the 3sfe doesn't have tvis.
    also stock 165 motor is only 190 hp
    hell throw in some frame conenctors and you'll be fine.
    talitha has a sw20 motor in her convertable and a molded kit and it seems to do just fine.

    I had an 88 All-Trac, and I guess that I got confused with the T-vis. I really miss that car; someone smacked me in the back right after I restored her, and, of course, the repairs were more than the value of the car even thought the damage wasn’t that bad (trunk and a side panel). Lucky for me, the insurance company, State Farm, did pay extra because I was able to prove through receipts that I had new equipment installed on her.

    Honestly, the car I have now can do 0 – 60 in 6.5 seconds. She is sluggish at start, and then once the revs get up she takes off. I can understand why your 3S-GE will not do that in San Fernando, California. First, you are 1000 feet or so above sea level, which means that the air is not as dense as it is here because I am actually below sea level in this part of Charleston. Second, you have more emission control stuff on your car than I do. We have no automobile inspections in South Carolina, and I am sure you understand that my Catalytic Converter just might :wink: have a big hole in the center, and I am missing weight from the roof, back window, etc.

    I actually was thinking about the ST165 as I agree that 190hp would be just fine and that it would be the best solution to gain what I want; however, replacement parts are now hard to find. It was a real pain when I restored mine, and I had to replace wires by hand rather than just being able to purchasing a new harness. Cost of a Turbo conversion is another question since I have already been down that road with an insurance company.

    I'm afraid that I am ignorant of the sw20 engine, but I will look online for the specs.

    Hey, thanks for the input. Thanks to your comments I have realized that the 3S-FE must go, and I must check to see if I can get parts and/or repair manuals for either the 2nd gen 3S-GE (170hp NA) or the first gen 3S-GTE (190hp-Turbo). It has been 3 years since I checked, but last time I did I found a JMD ST165 engine for $1100, and I don't have to worry about an EGR valve here.

    lol i own the last new harness. no shit.
    but i can get everything besides that and on the other hand you can use a 185/sw20 motor just as easy.

    With it being Christmas time aren't you feeling generous? If you send it to me, then you will have good feeling the year long. :lol:

    edit on last post....i didn't write poop, but oh well.

    and send you my new harness??? are you mad. it took 3 months to find it and 800 bucks. so i'm feeling good looking at it in my car.

    on the flip side. i do have a used harness with 90K on it. as soon as i get it from ashley i can inspect it and decide on a price for it, so we can talk then.

    The funny thing is ...now im not bashing
    I own a 99 mustang gt , which is considerably faster than my gts .
    You say you do 0-60 in 6.5 seconds in a (at-most) bolt-on 3s-fe.
    The mustang ...Verified is about 5.2-3 if i drive great to about 5.5-6 secs
    It weighs 3200lbs ..
    Have you seen my celica ?? hehe
    Its fully gutted,no cat,header,6pt cage,5 speed , 3sge w/t-vis
    Now im gonna have to go time myself tonight ...Just to see
    It weighs 26xx lbs verified on a public scale
    You do have 1000 feet ...but in my experience from racing out at palmdale which is about 2600 ft i believe ...A car thats faster at 2600 ft will be faster at 10 ft .....When should we race ?
    I like to think i know what im talking about ....
    Have you weighed the celica ?
    Is it a coupe or liftback ?
    What other cars have you raced ?
    Oh yea ..and i dont have Egr either ....No emissions equipment :twisted:

    believe it or not the fe should take you off the line. much better gear ratio and more pep to the motor. other than that you'll win.

    Well, I don’t race this Celica as she is a sports car and not a race car. She is a rag top. Soft top on a race car, no way.

    I’ve only raced American Muscle cars. There was a 74 Buick Le Sabre with a 455, an Olds Cutlas 442, Mercury Cugar and Montego both with a 351 Cleveland, etc.

    More horsepower doesn’t always get you better times. The Corvette has 400hp while the Mustang GT5000 (Shelby) has 500hp, but I would rather have the Corvette as it has better track times. No offense to you either, but I’ll take on your Mustang in my 2003 Saab 9-5 Aero with only a 2.3L 4 cylinder High Pressure Boost Turbocharged Engine. You want to see the track times for the 2001 which had 20hp less than the 2003?


    I have never had times as great as theses; mine will get to 30MPH in a couple of seconds, but takes more like 4-5 to get to 60; I’ve never timed her officially. I’ll tell you this, if you ever need an executive car for clients, etc., then you would love the Saab 9-5 Aero. She will not corner like a Celica, but she has awesome power with the high boost (sports mode), and there is no noticeable turbo lag. The new 9-3 with the modified Holden motor measures 0 turbo lag.

    Perhaps you should bring your Mustang to the South Carolina coast; I think that you would be very happy with how much more power you will have here.

    I understand that it is hard to believe, but I know what I have seen and timed several times. I am only unhappy with the 3S-FE because she feels sluggish for the first 2-3 seconds or so, but then she kicks in at the higher RPM’s and really takes off in second gear.

    Merry Christmas folks,

    Then why talk about how fast it is ?
    And if you dont race ??? whats up with the next quote ?


    Your opinion ...IMO id own the mustang ...

    Was this supposed to make me aware of a Re-bodied Wrx?
    15.9xx @ 88.xx mph is not too impressive IMO
    FYI the stang runs easily about 2 seconds faster without trying ...

    I have driven them ...and They are nice cars !!

    Hope you had a good one !

    If you want to avoid a turbo and just have horses in a N/A engine then why not opt for a beams engine, you would get good power out of it and if you wanted a little bit more you could swap in a lightweight flywheel, a good clutch and while the motor is out of the car you could pull the head and get it ported or do it yourself, all it takes is being careful and practice, after that you can just play with timing and add a header, performance exhaust and cold air intake to the mix.
