Hey guys,

I just got my water pump and timming belt and fan belt replaced, and everything seems fine and much smoother then before, how ever when i slightly rev the car and let go of the thorttle, the car makes a weird flutter like sound. I do have a k&N Pod filter and its pretty loud, but this sound is nothing i've heard before. and the thing is i cant see how the sound would be linked with any of the repalcement parts. Its ahrd to tell if the sound comes from the Pod (cos its pretty distinctive) or the engine. If its the pod, im fine but if its from the engine i might be a bit worried. I wonder if anyone have a idea what it maybe? I appreciate that it is next to impossible to guess for you guys without actually hearing it.

cheers,

Din.

Do you have an aftermarket blow off valve? If so, adjust the spring tention and make it a little more loose. Let us know if it still does it.

Na man the cars auto so i just got a stock B/V! cheers for the reply though. I should Prob also add that the car is:

1993 R33 GTS-T Auto.

Engine Mods: K&N air filter, Apexi N1 catback exhuast and Boosted to 10 PSI through a Turbo Smart Bleed valve.

im pretty sure the engine wont idle with any vacumme hoses disconnected... it will stall... if all hoses are connected, try removing the BOV and make sure the spring isnt jammed or corroded...

good luck

If this happened straight after they worked on your car it will most likely be directly linked to the work they carried out. The chances of it being something unrelated are slim to none. Take it back to them and tell them to check it over.

      Because it is financially convenient for them lol. Why wouldn't they want to give you the lowest possible valuation for your car?

      Yep. @Duncan also shannons they will rip you dry and will be probably limited on how much you can drive. Also keep in mind that you always have to have it garaged with Shannons, with enthusiasts as per their PDS you can have it 2 times per week on the driveway for example.

      I had a generic 4" Varex rear box on my old V8, worked a treat for sneaking home late at night, it was as quite as stock when closed The car was "fairly" loud when open as it consisted of 1" 7/8 headers to 3" catted Y pipe, to 4" single, it did have a resonator in the mid pipe and only the Varex out the back I also hard wired in a Varex dash mount switch, as the key fob thing is a pain to use when driving I wouldn't recommend giving the beans when it is closed though as it creates a large restriction in the exhaust  It also can in very handy when pulled over for "random" breath tests or just cruising past the constabulary

      How To Fix Tacho, R33 (maybe)

      By stewart1 · Posted

      Here is the before and after of the scraping/sanding of the IC pads on the tachometer board for the fix mentioned in this thread. And yes it worked fine after. Just a note if you change any components on the board the tach calibration can be wrong showing the wrong idle etc...only problem is once it is installed back in the cluster you can't get to it to adjust...ouch! My fix was to cut out the calibration pot (the blue one) from the board and run it with two wires to the fuse panel under the dash where I could adjust the idle calibration once everything was installed. And yes I soldered everything up again including the half soldered components either side of the IC in my photos
