The precat was not the issue of the engine failing. It were the piston rings and piston design. Piston rings getting stucked by old oil leading to burning oil. Burning oil leads the precat inside to worn out fast and material getting then sucked by the engine leading to ultimate engine failure. Pre and facelift engines suffered by this design (even with the first 2 revised versions of the rings and piston), only the so called "optifit" shortblock which was provided after production time delivered no issues anymore. 5 speed gearbox for example where in europe equipped by factory with an LSD. ;)
100% agree with getting a hardtop. especially if u park outside i own a miata, installed new softtop 6 years ago and its already fukd up. GET A HARDTOP
Good and informative video! Just a few things to clear up tho. The pre-cat failure in the early cars is caused by the piston rings letting oil by in the cilinder. This oil doesn’t burn up and over time damages the pre-cats in the exhaust manifold, causing them to disintegrate and get sucked back into the engine. They fixed this issue on the facelift cars. At some point, most of the pre facelift cars will start burning some oil over time. As long as the pre-cats are dealt with this isn’t a massive concern. As far as I’m aware, the limited slip differential actually came standerd on the pre facelift cars aswel! I have an original Dutch Toyota brochure for the 2000 MR2 model year that under the specs and options lists the limited slip diff as standard. I also have a 2002 MR2 myself and can confirm, it has a limited slip also.
A 2zz swap makes this car come alive like you wouldn't believe it, and it's fairly straightforward as swaps go. Though with the original gearing it feels like a 1zz. I think it's the best way to fix the oil burning issue!
@@Dutch_Fake_Ferrari true - mine was a good used motor for 2500 euros. They are becoming rare unfortunately. You can always swap a VW 1.8T or a Honda K in it ...
Nice Video ! I can tell you tried to cover all bases, and you did it very well ! I'm a MRS owner, in France, ( they scrapped the "2" of MR2 here because mr2 means "shit" in french !) To just reassure people, I wouldn't be so arsh on the SMT gearbox. Mine has one, and I like it. It's essentially the manual gearbox with an electronic actuator so the gearbox is the same, but controls are different. It's prone to be a little more complicated to troubleshoot if it fails, I agree, but it never failed me so far, and I haven't heard a SMT owner complain about the added bonus of having it. What about the fun to drive a MR2 with the SMT?? You focus on the curves, and the instructions to gear. The SMT switches gears for you, but will not do it if not asked for, also does (pretty fast) double clutching with revs up on down shifting, which just print a smile on your face ! The car is very fun to drive, and she is your best buddy on the road (that's how I call mine), but also, she's always pushing YOU, you don't have to ask, she wants it ! Which, as a hands on car lover for a long time, I can say that I love this car. It's a semi modern car, that stayed simple, pure, and provocative all the while not blushing to anyone in performance. The SMT was a less purist move to the roadster spirit, but is absolutely not a drawback, because very capable for fun purposes, and the performance of the MR2-S justifies it! That SMT was made to show Porshe they could do PDK-like boxes, and shifting time wise, the SMT is not far behind a PDK. ;-)

Pinned this comment, thanks for the additional and useful info!

This is a fantastic video, very necessary info.
Thanks!

Sadly the most expensive one as well 💸🥲

I want to try one now haha
@@Dutch_Fake_Ferrari Come on down ! I'll let you have a taste !
@@benjaminrohrbach5547 Sounds like a good idea! Can you contact me on instagram? Then we maybe can work some things out!
