Looking For Some Advice On My First MKIII :)

Sorry for not replying sooner... I'm surprised no one else responded yet.

All I mean by this question (I know it's somewhat naive) is how strong should they be going up until I will start to probably look at replacing some things or it needing repairs if it is being maintained relatively well? I am just curious to know so that if I do come across some ads I can have a rough idea when I see a KM read... (or miles lol sorry I'm Canadian ). And I say this all knowing that mileage doesnt really mean too much if it's maintained and kept well but just using it as a rough estimate.

At 20 years and older it's not so much about mileage anymore. I've got a friend with a 300,000mile MKIII which runs insanely well. I've worked on a 70,000 mile MKIII which has cost the owner an absolute fortune due nothing more than poor aging of seals and hoses...

Find a car and don't buy it until you have a mechanic YOU know and trust do a complete inspection on (including compression test, leak down test and pH coolant test). If they're running anything heavier than 10W-40 in the engine (which really is even too thick for most of the climate up there) I might be inclined to walk... usually people only run thicker than the recommended 0W-30 or 5W-30 because they're trying to stop it from burning oil as quickly or they're ignorant, neither is a good thing. Pull and read the spark plugs, this will tell you a TON about the state of things... Don't stop at just one though, read all 6!

I know for most cars it isnt even worth it due to it costing sometimes more than the car itself is worth... but I am wondering if I was able to find a TT one and convert it, it may end up being equal to putting a TT in a stock manual?? Logic flaw?? I dunno lol.

An engine swap is usually much more of a headache than a tranny swap... a lot more parts involved and a lot more stuff to go wrong.

You won't know this until you get it home and start finding what's broken. As a student on a limited budget you should really forget about upgrades and focus more on getting the vehicle nice and rock solid. If it is in immaculate shape then focus on supporting upgrades first: fuel system, brake system, suspension...

It's definitely less expensive to buy a turbo'd Supra than to turbo a non-turbo model... in the long run. I know if I had it to do over again I would definitely not have bought an N/A or I would have sold it instead of turboing it.

There are no kits for adding a turbo to a N/A, there are only upgrade kits for already turbocharged Supras. The upgrade kits can be installed on a N/A but there is additional work such as adding oil cooling and pulling (or at least lifting) the engine to add an oil drain for the turbo and then you also need to beef up all of the fueling system.

Put simply... if you want a turbo'd Supra but can't afford one... then wait and keep saving.

For example here is a few that I found, it seems like such BS lol..

Good eye... they ARE complete crap. I'm not even going to bother with the specifics... they're a flat out waste of time and money (cost about $3 to build one and it's still useless).

1) Brakes (gotta be able to stop from those higher speeds).
2) Suspension... driving a trampoline at 120MPH is terrifying and deadly.
3) Fuel... nothing worse than going lean as hell in the middle of a hard run and warping something or melting a piston. This includes fuel management (Standalone ECU or a piggyback system).
4) Oil and water cooling systems.
5) Exhaust
6) Intercooler and piping.
7) Turbo



Good luck!
