Performance Hello i have a 300zx turbo and she runs great,but i want to start to re-dew parts of the engine for more power and performance,ware should i start first? Shaun from cleveland ohio

never ever let any NISSAN engine CAM belt fail
or bend the valves over in the heads, or worse.
gee the engine is listed and maker as the only cars made that all their engines are INTERFERENCE engines.
5 engines used that year world wide, here they all are.

2.0 L VG20ET V6 Turbo (200Z, 200ZG, 200ZS)
2.0 L RB20DET I6 Turbo (200ZR)
3.0 L VG30E V6 (300ZX)
3.0 L VG30ET V6 Turbo (300ZX Turbo)<<<< bingo i guess.
3.0 L VG30DE V6 (300ZR)

this is normal. for high performance engines
to run 2 cams and huge valves and super high CR compression ratio's and lost of extra power (say from old push rod engines)
the Pistons, chase the exh valves closed super close.
this gains huge power, this act. (cam timing did)
so are interference.
but no engine told or country, told.
so no exact answers are possible. lacking that, or USA VIN if is USA>
in some countries they de-tune and engine for marketing reasons.
or what ever. IDK.

what a shop does is not crank it more and bend it more.
we do a BY HAND cylinder leak down test. or just inspect the cam timing using just EYEBALLS.
the manual for the car SM says do not move crank with cams not timed. clear as day. ever read a SM service manual?
page 1 , on timing belt page states this../

All 1984-88 Nissan Z and ZX engines are equipped with timing belts. Since these engines are of an "interference type'' design, if the timing belt breaks, the valves may contact the piston heads and cause extensive engine damage. Therefore, regular timing belt inspection and replacement is very important.!!!! oops <ignored this?
60k to 100k miles they fail, use Gates belts to run 100k.
MILES. if not in USA covert that to KMeters>
better engines are chain drive cams and not mix/belt/chain.
some cams need cam locks to do it.

cam wheels are at 11am left and 1pm right
and crank is very odd this. engine



belt tension is 22lbs (top center) RTM read the manual carefully

Hey, Give your reference some information about those tools ,performance and gas mileage,http://www.xcardiag.com/search/?q=Flowtech+50051FLT+Raptor+Turbo+Performance+Muffler

Sort of.
There should be a relay that provides power to the pump when you first turn the key on.
Then once the engine starts power is provided by way of the oil pressure switch. That way the pump won't run in an accident.
The oil pressure switch grounds the fuel pump relay on some models.

The cheapest way to get some increased horsepower out of your vehicle is the change the plug and wires to an upgraded aftermarket, also change the cap and rotor is your vehicle has on again after market performance. Those are the cheapest way, remapping the ECU could cause you issues with other parts in your vehicle.

Yes, replacement can be pricey. The engine is de tuned to allow for the pressure of the turbo, so without one you will not have much performance.

Have you had your mass air meter checked or replaced? This is the unit attached to the air intake hose behind your air filter. It senses the air temperature, speed, density, etc... and adjusts the fuel/air ratio to keep the vehicle running at "peak" performance. Also, check your TPS (throttle positioning sensor) it can also cause the problem you speak of. The TPS adjusts your engine speed/idle etc. and also compensates for hot/cold changes etc. This is roughly a $35.00 part and in most cases usually an easy fix.

its running very RICH !!!! TOO MUCH GAS!
check the air fuel mix & the air filter!
it needs a good tune up!
& get the injectors either cleaned or replaced
the fuel injectors from the factory are renound for leaking & setting fire to this model!
you can buy aftermrket injectors that eliminate the this

sound like transmission slipping .fuel filter clogged.turbo stop woking.dirty fuel injectors.

I might have a solution. I have the same problem. I just got an 09 accent and I think it is going to be a great project car to performance up but have problems finding parts because it is so new. I found a company that can help us with our problem. They are called KFX Performance, it is a specialty company for Korean aftermarket car parts. The only problem the representative told me, which you can get his info. on the website, is that they are having trouble bringing out the parts because I believe he said of either patent or demand problems. He did state that soon they are going to put the parts on sale. When I talked to him on the phone I stated that they would have plenty of people buying their parts because of the growing accent community, So do me a favor and help me spread the word so we can get some good parts going for this car, I am with you on the performance thing. The representative stated that in the future they are going to bring out the headers and possible turbo kit, I know nice. They offer headers now for a 1.6L engine but it is for the 06 Kia Rio. He told me to go to a Kia dealer and find out if the 06 Rio and the 09 accent share the same engine set up, if they do then I can be gold for a custom header job or I can just wait until they come out for the accent. He did state that just with their headers that they offer now you can get 9hp and if you get a high flow cat you can get another 9hp as well, very nice and with a AEM short ram intake that is a great start. Let me know what you think.

What engine do you have? If you have the 1.8 turbo engine, you absolutely need to run synthetic - the 1.8T engine is known for oil sludge issues, and running synthetic will stem that a bit. You'll still have sludge issues, but they can be held at bay. Use synthetic oil only, and do a treatment with SeaFoam (available at parts stores) every third oil change, and you should be fine.

Now, just because you need synthetic oil, does not mean you need to pay $13/qt for it from a dealer. Mobil1 synthetic is excellent oil (I used it for years in my 500+hp twin turbo 300ZX), and it's on the official Audi list of approved oils (Audi and VW are part of the same conglomerate). It runs less than $5/qt. Get Mobil1, and your oil filter, at the parts store, and change your oil at home - it'll take you 20 minutes or so and save you a bundle.
