The cars do give the power what Nissan say but as Jez and ourselves how found you do get an occasionally car that doesn't give the bhp it should and to be honest we cant work out why , you might be correct Neil run in procedure usage could all be the reason some cars don't give good stock bhp. We have found you need to give the car 4/5 runs on the dyno to get the car run consistent bhp.

Yes Direct replacement;

And if the cam/s was stuck it would throw a CEL anyway. Very strange. So what did you do to the map to gain all the BHP other than fitting de-cats , maybe the cats where struggling to flow the exhaust gas?

strange Jez, Maybe something to do with cam timing?

So what wheel bhp did the car run? Dyno dynamics rollers? Rotortest are the same idea as the dynapack , the website Wasso posted up was just a car being run on a Rotortest to get a stock car figure reading at the hubs. We normally see around 230bhp @ the hubs.

Milltek have now developed a system for the 370Z now ,We are just waiting for a price and delivery dates; Sneak preview of the system below thou; By abbeymotorsport at 2012-06-11

same as the counter shaft. If you have the workshop manual , it will show/tell you how to strip the gearbox.

Think we have spoken via PM before , to change the bearing is a complete gearbox strip , your need to remove the gear cluster from the gearbox casings , large press and a puller are required to get the gearbox apart; The input shaft bearing will always have play side to side as it is on located on the mainshaft only via a spigot but when it is fitted into the car the front of the shaft is supported by the spigot in the flywheel/crank thus supports the input shaft. I would say if the noise is always there when the gearbox is being deiven clutch up , it will be a constant motion shaft bearings as these are driven all the time.

LOl @ #hfb and SS reply, Yes hfb is a good friend of mine, we are all motorcyclists , well hfb was until he had his small accident a few weeks ago. My wife was on the ride with hfb when he had the accident; So I am involved in trying to find a Roadster.

Blue is Azure isn't it!

Got a customer that wants to buy a 350Zed Roadster; 2005/2006/2007 Blue/Grey/White Lowish mileage , good service history but can be main dealer or idependent serviced; willing to pay up to 9K. email mark(@)abbeymotorsport.co.uk o give me a ring on 01883 732331 ext 2. thanks;

On the bottom graph the lower dyno plots drops off early than the higher dyno plot? presume the finish run rpm where different. Also the top graph the higher number was on a short rpm span run so it isnt a true comparsion. I know Dan does a step and normal power runs but I cant understand these dyno plots? Also looks like he runs the car in 5th gear. We run all the Zeds in 4th gear so any one with a Abbey Dynapack run can compare there runs between them.

You cant compare the torque between the hub and wheel dyno but the gains are always approx the same.

flick the ignition on and off 3 or 4 times , that will prime the fuel system , then she will fire up all okay. If the car wont idle and was showing 40 miles I doubt the car has run out of fuel but something else will be causing the non running /bad running problem.

To make the most BHP from a Zed whatever model you need to run De-catted. Running Berks or any HFC's will always make more mid range Torque and a few more top end bhp but if a cat is fitted weather it is a HFC or a stock cat it will limit top end BHP on a N/A car. The stock exhaust and stock Cats will flow decent bhp especially if the car turboed or Super charged, I have just finished a TT 350Zed HR car still fitted with stock Exhaust and Cats and it made 420bhp hub and 400 lb/ft of torque easily.

To gain more than 25bhp on a N/A car is very hard. Look at your gains from before to after the dyno.

350Z all the adjustment is on the bottom 2 arms, rear link for the track front link for the camber, Eibach do a nice kit that works well. Graham, looking at the picture you have posted , all the cars look like they have to much right rear camber , but the road has a lot of camber as well so the car will be meaning over to the left as well which will make the car look like it has more camber. Both rear cambers on your car where as follows; left rear 1 deg 54 mins right rear 1 deg 59 mins. any questions ask away.

Hi, HKS have never produced a kit for the HR. Model car and the chargers used on the HKS kit now use a S/C kit made by HKS themselves. 2 kits are made for the 313 model cars 1, GTM kit that uses a Rotorex charger they do make a couple of kits but only 1 of the kits will fit our RHD cars. We will be fitting our 3rd kit later on this month both previous kits produced 440+ hub bhp very easily and safely I have no issues with pushing the motor's in the 313 model engines to this sort of bhp we even keep the stock clutch on this type of bhp/torque. 2, the Stillen kit that uses a Vortech charger, not fitted one of these ourselves but my friend in the US has fitted and tuned a kit, it doesn't produce the figures like the GTM kit. We always fit a fuel return system together with larger uprated injectors tuned with the Uprev software, keeps the cruise control, multi maps full normal car diagnostic's and car will run like a stock car. We advise a oil cooler and if your going to track the car a sump extension is advisable as well. We can run with either de-cats or HFC's and a stock exhaust can be used if needed. If you tune a totally stock car including oil cooler and sump yes you looking at a lot of money but we can tailor a staged conversion to make the upgrade more managable. Any questions ask away , email me mark(@)Abbeymotorsport.co.uk for more details or give me a ring to discuss. Mark

I never advise anyone to fit header unless the have the motor out for other work , the gain I feel isnt worth the money it costs to fit a set of headers to a Zed motor. SS had headers fitted as we had the motor out to rebuild .They are a easy fit when the motor is out; Mark

Darren been rather quiet on here , wonder what he has been up to.......more mods I bet!!!!!!

dyno plots are further up the thread. Pleased your Happy Darren.

I have a customer that wants to upgrade his HKS Supercharger kit very soon , so this low mileage kit will be for sale very soon; Would that be any good for you? , works really well on a stock Motored 350Zed with the supporting mods to handle the increased boost pressure;

Just had a Uprev delivery; just a quick reminder for you guys; As you know we have been tuning the Zeds both 350 and 370 Zeds with the Uprev software for over 2 years. We like to tune the car on our in house Dynapack dyno with good results. But there are people that would like to be able to tune there car there selves or that live to far away from Abbey to make the trip worth while, so we can supply Uprev equipment to allow; 1, For someone to be able to tune there own car with the Uprev software if they are happy to tune there own car. 2, Owners can log the ECU and then down load logs via a computer running Windows send me the logs I will then tweak the map and return the map to you for you to upload into your ECU ( the early JDM cars cant cant log the AFR so on these cars I will need a dyno pull with AFR on to enable me to remote tune these cars) I afraid I cant remote tune a F/I car and the 370Z will illuminate the bonnet lifter light , we are working on sorting this as we speak. Prices are as follow; Osiris Tuner £535-00 inc vat (comes with 1 car license) Osiris Standard £375-00 inc vat (comes with 1 car license) ( 3 tunes included, normally take 3 get get the map sorted , any other remote tuning after fitting other items will incur a charge of £72-00 per map. Cipher Cable is £160-00 inc vat only enables you to datalog or turn off CELS. any questions ask away
