question on TII reliability
 
Hi i own an FD (i'm sure you all know how reliable those are:) ) ANyways i was just wondering how reliable the TII's are? Do they have many problems or shortcomings?
And if so, is the maintance as costly as maintaining an FD? Thanks alot for the help. -Jeff

I was going to make a post like this. If the vehicle is taken care of will it take care of you or no?

I don't think ANY car is as much $$ as maintaining an FD :D

A lot more reliable than an FD!

But are TIIs reliable? I mean is there a big difference between the TIIs and the NAs? I am really thinking of getting a TII but it will have to have a fresh rebuild or be cheap enough for me to afford a new engine. I want to start off right so problems don't come up(or as few as possible ;) ).

Well, IMO the most problems with TIIs come from the not-engine. The ABSV, BAC, thermowax, secondary injectors, ecu grounds, etc, etc are the source of 9/10ths of the common issues with these cars. If you can find a car that idles well and has good compression, chances are that you've found a good car - no new engine necessary :)

Keep in mind as well that 2nd-gens' problems are much more hands-on. They tend to not be the sort of thing that you would drive to a mechanic to fix. The wiper relay is a good example.

The turbo control system is much less complex, but still prone to boost fluctuation (guess how I know). The 87-88 models have purely mechanical wastegate control systems, while the 89+ have a "duty control solenoid" that loves to die (and thus cause low boost).

The 3rd-gen and the TII are two completely different cars, both with their own strengths and weaknesses. I find working on a TII to be very rewarding. You must also keep in mind that at the NEWEST, you're buying a 12-year-old car - things like master cylinders and vacuum hoses tend to die. On the whole, however, I would say that a TII can make a very good daily driver in which you won't have to worry about popping hoses or killing solenoids.

I'm tired, and I'll bet that was pretty incoherent. Cheers! :o:

It depends what you define "reliable"... :)

The engine and drivetrain are pretty stout.&nbsp Unless the car has been abuses by the previous owner, the drivetrain will endure.

Like any rotary power vehicle, overheating the motor is sure death.&nbsp If the engine was overheated, forget it...

Like any turbo engine (piston or rotary), if basic turbo "maintenance" is followed, the turbo should last.&nbsp By this I mean...no abrupt engine shutdowns after hard runs, use good quality motor oil, don't romp on it until engine is warmed up, don't run too much boost.

ALL the 2nd gens have their quirks.&nbsp Luckily, a lot of the fixes are relatively easy and "cheap".&nbsp I'm talking A/C Logicon, CPU, wiper cluster, power window switches, sunroof, etc...

If you're talking BIG power project (approaching 300hp or beyond), I'd highly recommend an engine rebuild if it's approaching 100,000 miles.&nbsp I've seen apex seals that come out of engines with this kinda mileage, and the apex seals are just too thin.&nbsp Asking to make such a motor with thin seals to make double the stock power is asking for trouble...
