Cheers mate, think ill go with the bypass trick had a look at the guide and not looking forward to pulling entire dash out, so ill bypass it tommorow, can someone confirm a couple of things for me, According to the bypassing guide, they used a inner hose of diameter @21mm, is it possible just to join the hoses with two barbs and another hose, if so what would the diameter of the barbs be, would they be the same at 21 mm, or go for 20 mm barbs to really clamp the b@sterd of the thing down

Stupid bloody heater thing, lucky not so needed up here in QLD as much as down south, also after this i need to source a wet carpet cleaning service, so they can wash the carpet or a self service carpet cleaner similar to the one at 8 mile plains carlovers but i think that one is out of service STIl|LL last time i checked it was. or on another note would it be worth while to replace the underlay/sound deading stuff with new stuff or let it dry? as far as i know ethylene glycol substances are acidic? ie. radiator fluids,

Hi just did mine .didnt do all this though. just took out the glovebox and air con part. unscrewed the plastic hoses from the core (4 screws in each) slid the core out the side. slid the new one in , put some silicone gasket round the silicon o rings and screwed the plasic hoses back on. DASH not touched. might just be that all is wrong with yours is those silicon seals either way if you can get the 300zx one its a quicker way of fitting

when we have heater core leaks at work, they generally try and just dry the carpet first! hot air gun and a bit bit of deodouriser for example... it's alot easier than replacing the carpet especially if you have just had the pleasure of removing the dash!

i'd say dry it and see how it goes... should be sweet!

Mine did the same thing about a year ago, and had it bypassed. Now I have bought a replacement core to go in and will, eventually, one day, maybe this centry, pull my finger out and look at whacking it into my stagea. But I really dont want to take apart the whole dash to, so going to look at accessing it through removing the glove box and trying that angle, mainly because I have a front passenger side airbag, and dont really want that going off at all :D

Waiting for a copy of FAST so I can try to firgure out how big a job it is going to be.

Good luck with yours!

      Biggest thing is you're okay!   It sounds like between the accident, and the drive home, it was a pretty torturous trip again! On the bright side, you took the opportunity to enjoy the event more from the perspective of a spectator, than as an entrant!   Sad to see so much damage to the car. It really has taken a HUGE hit in the front end. If/when you choose to repair, hopefully the rails are straight (At least from shock tower backwards). Hopefully the extra cage coming through there has save most of the chassis rails, and HOPEFULLY saved the motor too. Best of luck when you eventually get motivated to start pulling it down to check it all out

      Slight brake pedal stutter after new pads

      By MBS206 · Posted

      Sounds more like what Brad said, that it's mainly transfer. What pad bed in procedure did you use, and did you replace/machine the rotors, or just swap pads?

      By PranK · Posted

      The stutter is almost entirely in the pedal. I don't feel the brakes release and reapply as you would with ABS engaging but the pedal feels that way, without the brakes releasing. It only lasts for less than a second and the pedal is fine again. It's hard to explain, sorry.  I'll get under this weekend and just double check everything is tight. Fluid is at max where I left it.

      What bedding in procedure did you use?   When you say stutter, what exactly do you mean? Like it feels like someone letting go of the brakes momentarily and regrabbing them again to get you to stop? Re-reading your post, and that is what it kind of makes me think you're explaining, like theres a little bit of a jolt, likely just as you're reaching a stop. I've only had this issue once. And if its caused by what caused mine, you will want to get the car up on stands again and check it over. Mine was a case of a caliper mounting bolt coming out and letting the caliper rotate on the other remaining bolt and gave play in a wheel as it came to a stop. But not every stop either!

      Yeop... binned it   This will be a summary will not many pics atm and cbf  Fixed the samsonas - it was totally munched Put a new precision 7675 T4 on with proper split pulse mani Got to Sydney to get to car - drove to canberra to get racecar - drive back to sydney that night Next day all day at Plasmaman putting on new clamps cleaning some things up and adding another large engine oil cooler sitting at the rear above diffuser to keep things cooler Next day - Tuesday - on Dyno - killer wikid awesome pumped out really good numbers - more mid range and on lower boost levels Wednesday - first prac - all day again getting the suspension right - had to borrow front suspension again - out do a lap come in - out do a lap - in - what i had just couldnt handle the load at the more consistent higher speeds - got a lap in at the end of the day that was pretty reasonable  Put it this way that lap wouldve had me in 4th in Pro am for the whole event - with only 700 hp and used tyres Thurs first official prac day - lap out warm up - then entered a hotlap with above setting and 80% effort took corners 1,2,3 and into 4 car felt awesome -  rear came around out of nowhere bang into the wall near front on at whatever 140 kmph Done, over, gone Just one of those how did that happen apparently as all indications show nothing out of the ordinary Got to spend the rest of the time at the event like I hadnt done before - was actually Ok mainly as I had my family and my boy is 9 and got treated like a rockstar Long trip home, lost a trailer wheel in nowhere land, X5 airbag suspension gave up half way across nullabour and rode on bumps stops (its now completely fine) had to do a 19 hr drive day on day 3 as accommodation got screwed up so just had to keep driving till found a town with some Now to reassess - hopefully the motor and other things are OK but yet to be seen too. There is no easy fix there is no i'll just order that part and get it sent - we'll have a talk to people see what can happen and what the go is but at minimum its rebuild from scratch struts forward and alot of time effort and $ should and if I return and if but maybe/ when  I have the cage tied into the front strut towers - if I didnt have that things couldnt been worse you can say its just a front end but if you know what goes into these cars... you'll know what that actually means in reality   Car was very fast. Disappointing we just didnt get to show it Effort doesnt win you races though     Apparently this is motorsport !
