now thats what i call throttle response. listen to how quick it revs.

is the ecu mapped to suit the z32 yet? if not then i don't know if that would cause a problem. what is it doing that makes you think it is running rich? if it is poping and farting then it is running lean, not rich. if it isn't reading the afm it won't idle, or if it does it will hunt really bad (sound like it has the lumpiest set of cams you have ever heard). was the map sensor hose from the wolf blocked when the wolf was removed?

thats not quite right. the laws of gravity and inertia still act on the car so the outside tyres will still get more load as the force of turning still loads up the outside. however the inside of the tyres will lift off the ground. if having solid suspension meant that all 4 wheels had even loading even around corners the car would literally handle like it was on rails. they aren't registered as road cars, but under a class of sports vehicles. they are only allowed to do limited driving on the road. you can't just pop down to the shops in it. and the missfire system you are talking about is anti-lag. ash was almost spot on. the system is designed so that at low load (like when decellerating) the timing is retarded so much that the fuel isn't ignited by the spark plug. instead on the exhaust stroke the unburnt fuel gets pushed out onto the hot headers and explodes. this keeps the turbo spinning much faster and means that the car is never running vacuum. they can be setup to run 5, 10 or even 15psi at idle. but when driven on the road they usually change the ecu settings to remove the anti-lag.

i know people with pfc's piggybacked so that they still can use all the features of the stock ecu, like cold start, etc. don't know who did the work.

1. might work if you were racing on 100% pure flat concrete. 2. hate to tow a trailer with a 1.6L v10 . 3. need to find out what your weight balance is first. then you need to get it at the right height, and get it centred so it doesn't affect your left/right balance. but you'd be better off relocating current parts to help the balance. then retune your suspension. 4. as ash said, legality, and to maintain power. you will hear people talking about 'tuned length headers'. you need a certain length of exhaust to create a scavenging effect. this syphons the air out of the chamber.

wouldn't surprise me if it was due to production of parts being ceased. a lot of various factories in asia have been shutting down.

probably warped rotors. and when you get on the brakes hard they warp out, and until they cool down they are hitting on the pads. get them machined.

a new fuel filter can make it run a bit leaner. if the old filter wasn't very dirty, but had done a bit of work it probably didn't filter as well as it should and let more fuel through than in filtered. then when you put the new filter in it is a bit more restrictive.

wind as much timing into it as possible. that will help.

if the tune is lean on decel it can do it also. i had a pop at idle due to a vacuum leak, which was making the car run lean. but just having a big exhaust usually adds a slight pop since when backing off air is trying to force its way back up the exhaust.

best to change it, to be on the safe side. even if you just get a stronger pressure plate. the clutch plate itself will hold fine with a stronger pressure plate.

if it is a drift pig, or drag pig that you are after then they are great. if you want to be able to turn in a car park without it pushing the front, and squealing the inside tyre then don't get one. also wears your tyres more.

it could be the springs on the clutch rattling.

as wrxhoon said, twin plate clutches are on the noisey side.

i'm not a big fan of front facing manifolds that aren't aftermarket. choping the stock manifold means that number 1 and 2 don't get nearly as much air as 5 and 6. even though it is pressurised, there is still little airflow going to the first cylinder. and number 6 will be running rather lean. your afr's will stay the same, but each individual cylinders afr will be screwed up.

if it is the same car with the same turbo and you change the boost from 15psi to 20psi (using a wastegate set at those 2 pressures) then there will be no power difference untill the boost goes above 15psi when you have the boost wound up. from the moment the second setup goes above 15psi the power and torque will change. below that the will be 100% the same. if it is 2 different turbos then it comes down the compressor properties.

other causes are tps in the wrong spot (not set correctly), no cat/empty cat, exhaust leak.

this is going to sound stupid, but is it a fuel problem? i had to fix a mates 180sx that had dropped number 2, i pulled the plugs out, taped up the coils and all that. it would spark when i grounded the plug and turned the car over (with another plug in the hole) but i couldn't get number 2 to fire. eventually i checked the injector plug on number 2 and it wasn't on properly. the moment i toughed in it went back into place and the car ran fine.

thats the engine number, not the vin number.

pretty sure itsnot genuine, and been built by some guy here is australia. i'm sure i have that car in a magazine somewhere. he got a stock 4 door gts-t and replaced everything with gtr items.

could be tons of things. afm is a good start. i would also try checking the injector plugs to make sure 1 hasn't come loose. seen it before.

road bike frames are generally larger than mtb. the bearings are the same. and if you get a bike with 2" slick tyres, then change them to 1" slick tyres you will still roll tons faster. i am a qualified bike mechanic, so i know my stuff. and when they first did the testing when they brought the grooved tyres into F1 they found that they lowered corner speed (which was the reason they brought them in) but they raised top speed down the straights. so to lower the corner speed more to try to lower the top speed they reduced downforce, which just raised the top speed more.

i call shenanigans! sounds like the gauge is cactus. my work car at mold old work (it was a 1954 morris panel van) used to do 15mph when it was parked.

it would just be the ignition wire to the ecu that you would need to cut.

hahaha the owner comes in and sees the car hanging off the hoist and starts crying. chopper comes over and says... "harden the f**k up!"
