Shehan" Date: 13 Jan 96 12:54:39 EST Subject: Re: Frozen parking brake on MKII I've experienced the frozen parking brake problem on more than one occasion. Apparently the problem is moisture entering the parking brake cable sleeve near the caliper and freezing onto the cable. I haven't been able to fix the problem yet. I simply don't use the parking brake if the temps are expected to get below freezing in the near future. It avoids a MAJOR headached trying to free up the cable afterwards. You may want to try spraying a sealant or silicone grease on/around the mechanism at the caliper.

Or have you considered Michelin MXX3? Would like to use 16" aftermarket wheels since IMHO oem brake discs look puny w/ larger than 16's. Would like to mount Potenza S-02 205/55ZR-16's front and 225/50ZR-16's rear or MXX3 205/50ZR-16's front and 245/45ZR-16's rear. Will these sizes/combinations work/fit? What wheels similar in design to stock would you consider? Any comments, suggestions, railings at my lunacy will be most appreciated.

Ordered from John Broderick @ Mr.2 Performance Products w/ HB2 100/55W replacement lamps. WHAT A DIFFERENCE-I CAN SEE!!! For those of you who still can't see or need other upgrades, highly recommend giving John a call. Excellent service - all parts arrived intact in 3 days in spite of the UPS gorillas. Thanks, John!!! (Will be talking to you soon abt Tokico replacement shocks - that is, once I get rf wheel that was destroyed by Tire Engineers here in process of mounting new AO22 replaced. Long story abt wheel and AM I P.O.'D. YOU AIN"T SEEN P.O.'D BEFORE!#*!**!! Tire Enginees wants to replace the wheel w/ one taken from a wrecked MR2 out of Miami. Don't know abt that!) Sorry, got side tracked there - back to headlights. Installation very easy. Essentially, just remove oem sealed beams and put semisealed units in their place. Refer to Owner's Manual for replacing headlights and follow all directions listed there. Also, apply vaseline to connector pins prior to plugging in connector - will make future connector removal much easier and will help water proof connection. ------------------------------ From: "Kostas G.

If you connect a resistor in parallel to the thermistor (temp sensor) this will bring the activation temp to a lower value, the fan will turn on at say 45 deg C . In addition a much lower resistor connected in parallel again through a manually activated switch could operate the fan at will from the front panel. It is a simple alternative to increased intercooler efficiency. - --------------------------------------- >.

I must check sometime this but are you sure that this second pressure tap on the canister is internally related to the first one. Why run a second tap if so and not use a T on the feed line? I think this second tap runs in a chamber counteracting the first tap. When boost is present in the second tap it counter balances the boost in the first tap and the wastegate remains closed...boost being built up. I think this is to make sure that the wastgate will not open gradually from a much lower level but abruptly at the pre-fixed value of 0.8 BAR where the pressure on the second tap is instantly removed by function of the VSV valve . I think this theory makes much more sense. Also HKS requires removal of the VSV to wastegate second tap connection since their system will control the wastegate in a short of ON-OFF operation without any gradual...progressive... way at the pre-determined levels the control unit is adjusted to. - ------------------------------------- > Here's the way I think it works: When the ECU senses really high boost, >it kicks the voltage up on the fuel-pump.

They know 17.5+ psi of boost >on 91-octane pump-gas will blow a 3S-GTE unless it is run WAY rich. One has to take into consideration that the FUEL PRESSURE REGULATOR has a tap on its top that connects to the plenum. Through this tap the fuel pressure is adjusted to the rail in relation to the boost. The ECU will only control the duration the injectors are switched on-off but that is not enough at higher boost. So the increased boost means increased fuel pressure by which for a max on time of the injectors, more fuel is provided. The pump receives a voltage boost by removal of the in series limiting resistors to keep the fuel system pressure at a higher level to supply the increased fuel demand.... that is the input fuel pressure to the regulator must stay at a higher level to sustain coverage of the fuel demand without fuel pressure drop which could lead to a lean supply...very bad at high boost levels. It is very interesting to note that the stock turbo at least on my 91 model will NOT produce more than 1.2 BAR of boost at normal ambient temperatures which is a situation that the engine can handle. Without a FCD though this boost will activate fuel cut off. The FCD all it does is follow the PIM voltage into the ECU up to the point where the ECU would activate fuel cut off and just prior to this voltage level will limit the PIM voltage which at further boost would keep rising, to this level so as NOT to activate the fuel cut off at the ECU. I think that long before this happens, the determination of the fuel input to the engine is being controlled by the fuel pressure regulator through its connection to the plenum (boost conditions) than by the ECU via injector time control. >'91T > >P.S.

You can do equal or better with a more stiff rear sway bar. Best would be a fully blocked differential but that would limit your overall driveability of your car...no more street use!! If you change to a 93 unit, you will have to run mods in the speed sensor unit as it was changed from mechanical to electronic. A TRD LSD would be best...I have heard of another make...a truly mechanical unit...CHRISS gave me a hint but I cannot locate it. Say CHRISS could you look into this and let us know since TRD seems not very cooperative??????? ___________ ________________ ________ __ ___/__ | / /__< /___ __ )___ __/ _____ \ __ | / / __ / __ __ |__ / ____/ / __ |/ / _ / _ /_/ / _ / /____/ _____/ /_/ /_____/ /_/ (Kostas G.

Ahhh.. how nice. Now that it's gone bimonthly, it's a little rare for this to happen :) Inside was some rather interesting stuff. There's an article on an aluminum bodied, $42k celica GT-Four that will be marketed in Japan only. 3SGTE putting out 250hp in stock trim. "30hp more than the current Celica Turbo" I've heard these numbers bandied about quite a bit, although TRD will nearly rip your head off should you mention them, or ask what's different between the engines.... So, 95 Celica turbo (3SGTE) 220hp 96 Celica GT-Four (3SGTE) 250hp. Is the 220 number from intake restriction changes, maybe a slight boost increase? the 250 from that plus the head change? Any unfounded speculation :) ? I went througha list of about 20 major engine components with my dealer a few months ago to be sure the engines really were part compatible (between 92 celica and 93 mr2) such as heads, cams, pistons, etc - same part numbers are listed for both. - -mike +----------------------------------------------------------------------------+ | mikep@diane.csg.mot.com | Email to mr2_faq_request@diane.csg.mot.com | +--------------------------+ with subject "FAQ" for a copy of the most recent| |1993 MR2Turbo #223 FRINGE1| MR2 FAQ.

I suspect that it was taken off the road for the winters, but I can't be sure. Last winter had little ice or snow here in Northeast Ohio, so the car saw little road salt. This year is much worse, with the car appearing white rather than its actual red most of the time. Because I don't have the option to use another car during the winter and it is pretty dicey driving the MR2 anyway, I am considering trading for a better year round car (like a Saab 900 turbo or Audi A4 Quattro) on a lease basis. One part of the decision is: when the loan is up on the car in 9/97, will it be starting to rust and therefore worth little? How good is the corrosion protection on these cars? There certainly isn't a trace of corrosion now. I sort of feel guilty exposing such a nice car to salt, especially since it cannot be replaced with a new model. Anyone interested in rescuing a (still) pristine 91T from the salty Cleveland winter? Michael S.
