Just cut the rusty part cut off , slide a piece of tubing the correct size over where the joint used to be and weld it on, all sorted then , it is the only part that goes rusty on the 350Z cars. Only takes around an hour or so , so pretty cheap. Mark

Ian, whats the AFR when crusing on the motorway? 15mpg sounds like you may have a problem somewhere? Mark

Anlid, The trouble with a well set up plate diff is they can snatch on tight low speed corners , they require maintenance, they get super hot when used on a track (so much I would advise a diff cooler for extended track work) A Quaife will work best for a road car , they dont snatch like a plate diff , they dont wear out like a plate type diff. And are a reasonable price. Mark

We are still cheaper than any Nissan dealer and we do know the cars, £70-50 inc vat an hour in the workshop and £98-88 inc vat an hour in the dyno. We are still busy with Skylines still get a lot of cars that have been to cheaper workshops to have a job done and then they come to us to be sorted 100%. But beggers cant be chossers you get what you pay for in this world , cheap jobs aren't the best way forward. Whats up with the clutch? pedal sticking down? or going spongy? Mark

Buy a car that can have multi maps , so you need a car with cruise control All JDM cars if they have cruise can have multi maps and all late 05 (296bhp) UK cars can have multi maps if they have cruise control, we can then do you a map for 98 and 95 fuel, the cars if tunedwhen totally stock get better MPG than a stock car , we remap the part throttle part of the maps, to run leaner this makes the car give better mid-range torque and throttle response. Mark

In my opinon these cams wont work on a N/A car without raising the compression ratio. You need to rev these motors to make any more BHP. The stock valve retaining caps dont like over 7200rpm , the stock rod doesnt like 7500+ rpm. I feel if your going to fit cams , get the motor out, fit rods and pistons raisde the compression ratio to 13+ to 1. rebuild the heads with the correct valve caps. then the motor will give some better top end BHP but you will lose the great midrange the stock motors give with a good tune. Mark

Couple of questions, 1, how many runs did they do before they gave you your final figures? 2, how long where the runs? 3, Any AFR readings? These cars do give vastly different figures from car to car , when we dyno these cars we always get 6+ runs before we get an idea on the BHP output. We find the Revup/HR cars the worst for giving very low bhp output figures. Your find just bolting stuff on like air filter can or will not make any difference , the main thing in these cars giving go power output is a remap to suit your fitted mods. This has been covered more than a few times on this forum. Have you check if there is any stored CEL codes in the ECU? Any questions ask away.

ALL 350z,s will retune to the air fuel ratio that is in the template in the ECU this is what we tweak when we remap , the JDM is no different to any other 350Z I am afraid. I should know a JDM is my daily driver. I tuned this car, what he hasnt said we have priced to fit decat pipes and a XYZ Y pipe with a race cat , this is the preferred route will tell customers that works and isnt to noisy.

We carry the plenum spacers in stock they are £179-77 inc vat , no postage if from us we can fit it before we run your ca ron the dyno. Clutch wont be stressed any more than a stock car We have tuned approx 40+ cars now never had any hassle with any cars after we have tuned them. Mark

LOL, really but the HKS only makes half the nosie as well.

never seen a DE give 250+ lb/ft torque , what was the un corrected wheel bhp figures?

Plastic pipe works best as well , anything alloy holds heat so raising the inlet charge temp. Stock 06 box is best.

STOCK airboxes will beat any air filter system available. Mark

recon over 4K to reapir properly, definitely jig job , major damage.

Thanks for the compliment , I do use a keyboard but my spelling isn't very good normally only playing with figures on the keyboard so you lot are happy with the output of your Z,s. Motordyne dont make the Gamma anymore....;-( but we are working on a new system for the UK nice and quiet but with a sporty noise. Yes Dyla your car went very well for very basic mods , these Z,s do tend to vary in output depends how they have been run in and driven prior to tuning. I would say to go any quicker just drop the stock cats fit de-cat pipes and a XYZ fitted with race cat and a tweak on the map and you should see an increase in midrange torque and the BHP will carry on climbing to the rev limiter. have fun. Mark

Any fitment of Cats will hinder the output and spool of the turbo,s alot. We find that to stop the droan your have to add a couple of large exhaust silencers somewhere , which on a 350Z T/T there isnt a lot of room. Maybe worth looking at having another system made woth a rear silncer like a stock car across the rear of the car and put each bank exhaust into the side the exit on the opposite side. mark

not if you tune the car properly , just fitting the injectors without a remap will make your car run very badly. Cams we only say to fit if you going to rebuild the motor with higher compression to much work just to fit cams and get a very small return.

As Bodyboarder says running a straight through pipe will make the car a little louder , running the resonated silencer keeps the edge from the noisy doesn't sound as harsh as running with the straight throu pipe Mark

All 3 set ups will fit your car , the XYZ Y pipe, fit in between the stock cars and stock exhaust section. So the only thing you need to decided if you still running the stock postion cats if you want to run a straight throu pipe or a resonated silencer. These are priced as follows; With a straight throu pipe £428-23 inc vat With a resonated silencer £ 487-61 inc vat We have these both in stock.

.

We type do you require? , we are carrying stock off all 3 set ups @ the moment. Mark

Ben P, I presume you mean the De-cats; Resonated de-cats- these knock the edge of the exhaust noise if running without catalytic convertor in XYZ Y pipe they also give a gain in the mid range torque over running normal non resonated de-cats i.e the Berks. Stock De-cats will make the exhaust noise a little more agressive if running without a race cat in the xyz again will not give the midrange torque as the resonated Motordyne de-cats. Waitng , depends if I have any stock in, I think I have a couple of XYZ Y pipes with race cats , 2 sets of Berks on there way and only 1 set of resonated de-cats at the moment . Resonated De-cats are on order but will take 5/7 weeks to come back in stock. Hoping to have a exhaust from Motordyne to try out , we have had a think about what is needed from a Z exhaust , so we going to hopefully modify the TDX to run rear Gamma silencers hopefully this will keep the exhaust to a reasonable level. mark

Any uprev dealer can remap the UK cars , but we are able to LIVE map the UK cars now, which makes tuning FI cars a lot easier and safer. A UK car cant be lived mappd so you log tweak and send the map. All 350Z ECU,s self learn, thats what we play with when we remap a ECU we get the triming part of the map closer to the template AFR map. If you have fitted a Plenum spacer it will slowly revert to the mapped map , but if you reset it it will perform a little better for a while. Tricky once you see a ECU working live your understand how it all owrks and what I have been talking about over the last few months ( Fuel has 2 maps 1 , template AFR and 2, compensation. if the compensation is miles out it takes longer for the car to read the correct templated AFR ratio , if you add a mod, the compensation map needs tweaking so it is closer to the Templated AFR.) hope this helps. If you reset the ECU is cancels out the learnt fuelling so makes the car feel a little faster for a while till the ECU learns again

wouldn't be able to tell you but another hassle would be your need to fit a throttle cable stock ECU can work with fly by wire but your also need a vacuum pump to suuply vacuum for the brakes. In my view on a road car waste of time and money.

Drive in drive out. Mark
