13.4 second 1/4 for your 'stockish' R33. (A how to guide).


Recommended Posts

i got a 13.981 at calder last night... could have probably done better, but happy for a first real strip run. Set my 235/45 tyres to 16psi and I have pineapples on the back - seem to have less traction probs than some of the other gts-t boys who also ran.

What mods do you have??

a few :P its not really "stockish" though as the thread indicates...ah well..

S-AFC, cold air intake, dump pipe, hi-flow CAT, HKS Super Dragger II cat-back, blitz pod, HKS FMIC, ProfecB EBC, heavy duty clutch, pineapples, zeal coilovers, falken 235/45R17.. stock ECU, stock Turbo @ 13psi

i think some heat buildup and trying a bit too hard could have effected my later runs.. i'm gonna wrap some of my piping soonish to maybe fix that for next time.

thanx :( other runs were around mid-14 at higher MPH (~100).

Its all in the takeoff, which i'm sure you know, but its definitely what I found out on friday. The difference between a 14 sec run and a 13 second run is all in a good takeoff.

Easier just to just post the timesheet with the 60', etc.

If I can get that a bit lower (which I think I can next time), I think I may be able to get about a 13.6 or something with a perfect launch and my current mods. I'll be happy with that until I one day I upgrade the turbo, ecu and maybe a couple of other things which should push me into the 12's. 12's for a daily driver that is RWD would be pretty nice I reckon :(

anyway, enough about me.. back to general discussion

yeah.. other runs were worse launches, but better shifting after that, resulting in higher top speed of around 101mph

If i can pull both off in the one run i'll get somewhere around the mid-13 i think as well.. tyre pressure could have been a bit low @ 16psi for street tyres??

I ran 14.370 @ 98.79, 60' 2.407 with a pod (no cai) and a 3" cat back zorst. I believe that 60' time could come down a few tenths with a bit of practice (I only had 3 runs on the day).

I just dont get it. predator666 you've got some decent mods I'm guessing they'd be around $2k rrp? Surely to goodness your $2k mods are more than 0.3sec better than my $400 mods? It looks like you can launch it better than I can also.

A question for all: How much did you spend (and on what), and what affect did it have on your times???

Most of the stuff came on my car.. but if u added them up prolly $6000-$7000 or so :P read back a page for the full list. 0.3 is a reasonable difference.. and 1 second is a massive difference in terms of what you need to do to your car most of the time.

That run i felt like a pretty perfect launch, and i took it a lot more easy on the gear changes afterwards. Maybe i backed off right at the end? (no idea). Anyway, its all in the timesheet up above, i'm no expert, and i don't remember every single detail! I only had about 4 runs.. next time i go, i'll hopefully have some more runs, and hopefully get a better time as a result of the practise.

Waming up your tyres with a burnout is good for show, but not really going to help you on street tyres.

I ran at eastern creek again last night and got a 13.102 @ 108.46 mph, killing my old time of 13.7 @ 105. I was much happier. My 60ft this time was much better, of 2.114 over 2.365.

I walked away grinning from ear to ear (I was hoping for a 13.4) :) :) .

I have standard internals, injectors and fuel pump. I am running a custom plenum, XF trottle body, FMIC, EMS management, high flowed turbo (metal wheels, no bb centre), running 17psi boost, exhaust, etc.. The tyres are 255/35R18 Fulda street tyres let down to 20psi.

Here is a pic of my engine bay,

They are close but still handling it. We have looked at them closely on the Dyno, but they are still upto the task at the moment. I am looking at a bigger turbo at the moment, so I will have to do something about the fuel system soon.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
