As Jon has said. Communication with your tuner is key.

Andy, Do not start up your car mate if you fit the Dastek Unichip as you will cause expensive damage. The Unichip will not revert to base map if it was mapped for FI. Fueling (injectors) and ignition being the main issues. Best leave it to the "experts" mate.

£883.12 each to be exact.

Is it the front sensors on the manifolds or the rear sensors after the cats ? If it is the rear sensors then you will not require to replace the sensors as I have a cheap fix for that as I posted previously. What were the fault codes ? Alex. Alex, I was told it was the front sensors, so maybe not so cheap a fix... It appears that it wasn't damage caused by bottoming out, but general wear and tear... (maybe scraping the underside of the car pushed it over the edge!) I haven't picked the car up yet, possibly this afternoon, but I'll definately post up fault codes if I can get them... Thanks again for your advice. Ross I doubt very much if the front sensors are faulty but if they are then I do have spares if you need them.

A pleasure to meet you as well Derek and glad that you had fun. That is the first time that I have run the low boost map (.85bar) Usually I run at 1.2 bar but I wanted to get some data to compare with. The car was 1.7560 secs per lap slower on the low map (which I ran with for the complete session) and my up gear changes were all at completely different positions on the track as it was taking longer to reach the desired rpm. All in all a great night and thanks for coming. Cheers, Alex.

Here you go mate. This set is as new with no marks, scratches or kerbing. Finished in black / chrome Drop me a pm if interested Cheers, Alex.

Ross, Best to get the car on a ramp and have a look at what bottomed out. The o2 sensors which screw into the cats are recessed and fairly high up so I doubt if you will have damaged them. The o2 sensor has a 12" cable attached which plugs into a block connector under the gearbox. This is where I would be looking. If there is nothing obvious, I would still unplug them and check and clean the connections. Failing that, you would be best dropping into Nissan and ask them to check for any current and archived fault codes on your car. Once you have a note of the codes ask the technician to delete all codes and to reset the ECU. Your light will now be out. Post the codes up here and lets have a look at them. If the engine check light has been thrown because of a cat issue then I have a cheap fix for you. Cheers, Alex.

I was not aware that there is a difference to the handbrake set up between the two models, please correct me if I am wrong. Firstly you will always get a bit of "drag" on the rears due to the driveshafts. The best way to adjust the handbrake is to remove the ash tray and back of the nut on the cable, you will require a deep socket for this. Then remove the rear wheels and the rubber plug in the disc/drum Turn the disc/drum until you can see handbrake adjuster. Flick the adjuster round one click at a time with a flat blade screwdriver until the disc/drum can not be turned. Back off the adjuster until the drum is free to turn. Now do the other side. Finally adjust the cable from inside the ashtray. Check that handbrake is not to tight and the disc/drum is free to turn. Alex.

Me to, so apologese to those that have been waiting on pm replies from me.

Okay here are some pics of the Performance Friction Rotors, I only have 2 sets left. I also have 1 set left of EBC Front Rotors. I have 2 sets of Brembo front Rotors. I have loads of Ferodo 2500 pads. I have 2 sets of Brembo pads. You all know what the Brembo and EBC rotors looks like so no pics. Sorry sold my last two sets of DBA today. If of interest then just drop me a pm. Cheers, Alex

Hi mate I have available Brembo, DBA and Performance Friction rotors available. I will post up some pictures for you shortly. Alex.

Some pictures from the weekends Avon Tyres British GT Championship at Knockhill. Superb event with glorious sunshine most of the time. Enjoy

Tappet clearances can be checked in situ but to adjust you need the cams off and to get the cams off you need the heads off and the best way to remove the heads is to take the engine out. The heads can be removed with the engine in situ but it is very fiddly and there is a big risk of oil leaks afterwords. I have done it both ways and I now remove engines every time. Good news is, I doubt that it is a tappet noise that you have. Other common engine noises on the VQ35 are fuel dampers. Alex.

If it is a Brembo set up you have then it is eazy peazy but the JDM set up does involve a bit more work. If you are running Brembos then a brake pad upgrade to Ferodo DS 2500 should seriously be considered. Ferodo DS 2500 in stock and available at £180.00. Brembo pads in stock and available at £125.00 Alex.

to the forum and great to have another Roadster owner aboard.

The noise description that you give leads me to agree that it is a wheel bearing issue. You do not specify which type of PF pads you are using and you appear to be running oem rotors. There should be no issues with your calliper pistons but I am concerned that there is a discharge of brake fluid from the bleed screws if in fact that really is the case. As regards a brake upgrade, there is so much available but it will all depend on how much track use you have planned and your budget. I have Brembo, DBA and Performance Friction Brake Rotors all available and Brembo, PF and Ferodo DS2500 pad kits to match all applications. Hel and Goodrich brake lines and Motul Fluid also all available. Alex.

There is no fan belt on the VQ35 as such. There are two belts, the main serpentine belt and the aircon belt, and both are adjustable. If the starter motor is only sticking then a clean will fix it, but if it is an internal electrical fault within the starter then a replacement starter will be required, or it may be a faulty starter motor soleniod which is part of the starter motor. A new starter motor from Nissan is £420.40. I have preowned starter motors available at £125.00. Also check that the ignition switch is not sticking. Alex.

to the forum. Lovely looking car that you have there

They are £100.00 mate

Sounds like the pre-engaged starter is sticking in the on position for a few seconds. Disconnect battery, remove starter motor, free off, clean up and lubricate, refit starter motor and reconnect battery.

I am assuming that you know the background to the Nissan Works Rally Raid involvement in Motorsport and that the originall engine spec. would be as below. Nissan were very guarded on there internals but it would not surprise me if they were stock. What internal upgrades that have been done since, if any, would be anyones guess. If you are planning to run big power then best to strip and have a look in side. I strip and refresh my engine every 12 months as a matter of course.
