Project Na 300Zx

[Super Drager]

Hey guys, the plan with this car is basically to run a low 14/high 13 second pass while staying completely naturally aspirated so no nitrous/SC/turbo etc and while staying in street trim, so no stripping its guts out. Kinda want to do this just to prove it can be done and to stop people from calling NA cars slow, while they can't compete with a turbo $ for $, they do quite well for what they are.

Here are the Specs:

1990 Nissan 300ZX Z32 "Slicktop"

1430kg

131.4rwkw Dyno tested(previous owner)

Mods:

2.5" Twin UAS Catback Exhaust

2.5" Custom Front Pipes

K&N Pod Filter

Go Fast Bits Underdrive Pulley

F1 Racing "stage 3" 6 button clutch

Bought the car back in 2009 with a 2.5" Custom catback, UDP, Pod & standard clutch for $6200. Was a very nice looking car, atleast to me, and the motor was in perfect nick so i decided to buy it.

From when i first bought it

Not long after i bought it did i have my first go at the dragstrip, here are some photo's

After 5 runs the best i could come up with was a 15.017 @ 97.22MPH . My clutch was slipping on anything more then a 2500rpm launch so i had to take off really easy.

About 5 months after that my clutch decided to call it quits, held up well for a stock clutch IMO. After looking for hours i decided on my new clutch, a "Gripforce F1" racing Stage 3 Button Clutch. Oh boy did this take some getting use to for the first day, soon as i picked up the car i got stuck in peakhour traffic!

A good 1500k's had passed and the clutch had been well worn in i decided to have another crack at the drags, i HAD to get that 14 second pass!

Decided i would take it easy on my first run so i wouldn't stuff up, managed a 14.847 @ 95MPH first try! What was even funnier was that i had tried to select 4th but had trouble so i let off a bit before the finish line. Ok Second run, was really excited to see what i could get, time to see what it was capable of

Timeslip, a 14.6!:

Not Bad considering a lot of first gear was wheelspin and i hit the rev limiter before the finish line!

Video of the run

Rear tyres are chinese 235/45R17's and were set to 25psi during my runs. After taking my car to Unigroup Engineering, Yavuz concluded that i should be able to run a 14.4 Second pass with a slightly better launch as my 60footer was a pathetic 2.315 seconds.

Mods coming up:

1 Piece Lightweigh Tailshaft

Decat Pipes for the track only

Piggyback Ecu of some sort, Either an APEXi SAFC or NIStune.

Kumho KU36 Semi Slicks.

Looking to get that 60footer down to 2.1 - 2.0 to see what i can squeeze out of it, no internal work done standard heads & bottom end. I'm fairly confident it will pull a low 14 second pass, just have to wait and see, will keep you guys updated!
