I'm used to the ultra-reliable cars that Honda and Toyota offer when it comes to commuting, trips and overall use. Knowing about some of the weak spots in the 3rd generation RX-7 and my resistance to use one as a daily driver leaves me questioning the 2nd generation turbo cars as well.



1.) Granted any rotary engine is going to require more maintainence, what do you guys think of using a Turbo II as a daily driver?



2.) Would you say the Turbo II cars are more, less or of comparable reliability as the 3rd generation RX-7?



3.) Would you contribute the weaknesses of the 3rd generation to the complex turbo system and regard the Turbo II as "safe" considering that the Turbo II is not sequential?



4.) Are there any known weaknesses on the Turbo II models that need to be addressed and looked for?



Any and all information is appreciated.



Thanks.

1) it is fine i did it for six months....

2) T2 is more reliable

3) A T2 with boost under 10 psi is a happy reliable T2

4) Don't boost past 10psi or you will need a new engine

I heard you can boost pass 10psi with a FCD and still be reliable?I guess the injectors might be the limiting factor to reliability tho.

above 10 psi = new motor. ask me how i know https://www.nopistons.com/forums/pub...>/rolleyes.gif

Anyone know if it is typical to run into spiking and overboosting with breathing modifications? Like, could you install exhaust and an intake or what have you without having to find a way to control boost? Or is the Turbo II in the same boat as the FD?



Thanks.

Keep the fluids changed, dont overheat, and a Turbo II will last anywhere from 130k to 180k. I daily drove my TII to work every day and it didnt, and has yet to, give me any problems.



They are far more reliable than the FDs comparing stock to stock.







Other TurboII/FC problems;





The pinion seal on the rear diff has been known to leak.



Theres a pulsation dampener on the fuel rail that can cause a fire if not replaced.



Thats all I can think of for the moment, any other questions just post up!

basically they cannot control boost on a full exhaust..... you do TID and full exhaust it will hit atleast 15-16psi and then you will need to port the wastegate... to control boost

the TII is pretty susceptible to boost creep.



If you run a full exhaust, you'll be needing to upgrade the injectors, fuel pump, and ECU because the turbo will be wanting to see over 10 PSI probably. 10 PSI is the maximum safe limit of the stock fuel system.

Theres also the factory boost cut that you can get by with the FCD you mentioned, but I consider that a really half ass bandaid, and you are heading towards a rebuild if you get one.

What does the Turbo II run as stock boost?



Thanks.

5.5 psi for the 87-88 model years, 6.5 for the 89-91s. Plus the 89-91 turbo gives better power and has a larger wastegate to better control bosst creep.

above 10 psi = new motor. ask me how i know https://www.nopistons.com/forums/pub...>/rolleyes.gif [/quote]

anything speical about that new engine to handle higher boost? ..or is it just a normal 13B?



what if i were to take a street ported 13B and put some really big injectors on it, would it handle 10+ psi then?

bigger injectors and a programmable ecu, haltech, new fcon s, motec... etc https://www.nopistons.com/forums/pub...IR#>/smile.png

daily drivin the turbo two...

picked up the rb full exhaust as the factory exhaust is disintegrating...

although having yet to determine to go piggyback or standalone...

its not on yet...full exhaust just provides for a domino effect...

as others have already indicated..inj..fp..wg porting..dual alt pulley..etc...etc...

lookin for stock exhaust right now to squeeze out 50k on the 115k motor....

contemplated on installin the full exh too and lay off the throttle..

but itd be hard pressed for me to lose the weight off my right foot...

I know of one TII that is daily driven, it has a high flow converter, and a RB cat back, and a FCD. I think the guy is easy on the car, but he has been daily driving it for a few years now.

right now if i still had my TII i'd probably go with the new FCON-S ..... supposed to be pretty good!

My 87 TurboII was daily driven for the 2 years I had it and was still running strong at 120k miles when I sold it. The only problems I had were the tps was dirty or sticking and caused bucking on occasion. Usually a spray down with electrical parts cleaner would fix that problem for another month. The other problem was flooding. It happened only a couple times. Once actually wasnt really the flooding problem, it was failure of the cold weather starting system dumping a quart of antifreeze into the engine. I only experienced the real flooding problem once and was able to get it started without too much fooling around. Just be sure to completely warm up the car before shutting it off and it will never leave you stranded.

my 7 is my only car and i use it as a daily driver and it werks just fine

read the topic of the thread, and the thread itself, is a TURBO II

good for a daily driver.



Stop post whoring.

honestly....for a daily driven car that is fun and reliable, leave it stock. If you want to, put an intake on it for that little hp/thrill factor. Some all-season Toyo FZ4's and you have a above-par daily driver

My TII is a daily driver, and I have the folllowing mods:

DP/MP, Cat-Back, TID w/ cone filter, FCD, an accurate boost gauge (GReddy), and a Walbro 255lph pump. It's reliable as all hell as a daily driver; doesn't flood, doesn't overheat, etc. I keep my foot light on the pedal when i drive it normally, and only push it HARD every once in a while. It has, in fact, been more reliable than my convertible was. Easier to work on, too. I am going to upgrade the injectors and get a Fuel Computer this spring, just to be on the safe side, and I am porting my wastegate this week or next. I'd say get the TII as a daily, just be knowledgeable about it and don't overboost it.
