Ok guys I think i am in the right area.

My 89 Ceffy has been great, BUT recently only in the mornings when taking off it feels as though someone is pulling the handbrake on at about 2000 to 3000rpm but as I drive through it it goes away, and then starts over again in the next gear so on and so forth till the engine warms up about 15mins or so later.

pls help with this issue as it is giving me the shits as well as the G/F

Mine does the same... its as if it retards the timing then all of a sudden goes back to normal and gives you a nice swift kick in the pants! Again, only happens when the motor is cold. Doesnt retarding the timing increase cylinder temps therefore warming the motor up quicker... might make sense?

Yea mine does the same thing for about 5-10 mins (depending on weather), i think its just the engine retarding the timing to create more heat and warm the engine up faster, you would probalby find that if your cefiro is turbo the turbo starts spooling up earlier and with alot less throttle.

Does anyone know what sensor triggers this, is it oil pressure/temp or water temp or both?

i know this could be way off and slightly off topic, but would the fact that most of us are probally running the original auto computers (assuming with the limited amount of genuine manual ceffy's that were made) with now manual change anything with the timing when starting/warming up? (eg are the ignition maps different?)

anyway dude as i have mentioned and as jaik also touched on, check ur thermostat (could be siezed open) and coolant temp sensor (could be old and faulty/corroded).

other then that might be best to post ur issue up in the tech area as alot of r32 drivers would prob have experience/knowledge with such an issue aswel.

mine is a stock manual and it surges when cold for the first 5 to 10 minutes or until the temp needle reaches the middled of the temp guage ..then it stops ...so i dont think its that

I have had a 32gtst, tt300 and the cefiro and they all have done it, if you find out what it is then your up for a noble prise in my opinion. I think its the timing being retarded, or a faulty sensor as latley I havent had it everytime I have started the car when its cold. I did go for a thrash and that seems to help it for a little while. The other thing my car gets is a slight splutter at cold idle as well, so the retarding seems to be right.

hope someone fixes this dilema

      High temp brake fluid?

      By Komdotkom · Posted

      Reasonably hard, although I haven't run it with the new Endless setup yet. The old brakes were F50's on 335mm rotors and the car did a 1:40.6 at Phillip Island which is a reasonable time, I'm seeing high 600s on the temperature paint. A guy I know ran the Endless fluid at WTAC without issues and he was doing 1:33's I think (Evo) with a 355/332 setup. I don't get out to the track as much as I'd like but we put the car on the hoist and spanner check every bolt and re-paint mark everything, bleed the brakes, change the fuel, check the coolant system and re-bleed blah blah blah before every event. Motorsport is expensive, RB's are expensive so a couple of hours before an event is time well spent. It's also a net time saving because if you can keep your RB from self destructing it saves you time in the long term!

      Hello! I'm new here, I have an R33 GTST that is currently being finished up! Last year was pretty rough, blew two stock turbos so I decided to build the car. Has been down since November, but I get it back next weekend!

      Hello, I believe my car was imported to America in the 2000s by Kaizo Industries. Would anyone be able to help me find more info on them? I've only found all the basic stuff like that paul walker bnr34, them being shutdown by feds, just stuff like that. Any help would be much appreciated, thanks!

      HKS Vcam Step Pro Issues

      By believer · Posted

      I am using Motec M150.  I am not working on the car myself actually.  My workshop is giving all these info, they are quite reputable in the industry and are very familiar with Motec and RBs and have done a few big setups with VCam and single turbo on RBs.  In fact, they built and tuned my engine from day one.  But they are stumped with my engine at the moment and cannot work out how come the compression is so low with the VCam. They told me that they have now swapped in some Kelford cams (without the VCam) and can achieve around 130psi compression and the low end torque is better, but now the engine is doughy as.  It boosts and peaks at more than 1000rpm slower, with twin HKS GTIII RS, it doesn't get full boost until over 5000rpm. I have always thought the VCam was a bit disappointing at the low rpm. To a point I had to ride the clutch a fair bit to get up a small hill from stand still.  That was when I had a clutch.  Now changing to a 8HP, I don't have that luxury and this problem has become a major issue. I am beginning to think the VCam never work since the day it was installed.  Maybe it was just sitting at the most advanced point, that is why it went good at top end but very ordinary at the bottom.  Therefore, with the help of the Holinger 6 speed and paddle shift, as long as it was moving, it drove pretty good.
