Simply get more power to get better times

It really depends on how much money you have to spend

First probably get a full exhaust, then air filter, then cooler and up the boost.

After doing those standard mods you can do bigger things like change the turbo

Also because you have a gtst it'll be hard to beat a wrx off the lights because they are AWD. You will catch up to them once you get traction after some simple mods

* Pineapples ($150)

Forget the bigger turbo, the extra power you make out of it will be lost in hitting boost and putting the power to the ground. You want a constant steady power curve to give you instant power and the stock turbo will deliver more than enuff power for this.

If your -really- after a 'bigger' turbo just get the stock turbo hiflowed, once again it will deliver more than enuff power and will boost up similar to the stock turbo.

Now how many people spend heaps of money on their engine but forget that somehow they actually have to put all that power to the ground? Do yourself a favour and buy a set of good quality tyres (back atleast).

Pineapples will give the rear end better squat and will force the car into launching harder in a straight line which is exactly what you need.

Note: The only experience I have is reading forums, not putting theory into practice. But thats only until I get a good set of tyres.

okay, nice wide wheels at the rear will help.. trust em i know.. i have shit tires and it sucks getting off the line. Even with minor mods and only 10psi i can boot it any surface or i get wheel spin :)

My car also has a different diff, which gives more accel, less top speed - to changing your diff to a higher ratio should also help. I think a std is a 4.11, so a 4.5 or more could be good. Only thing it will put your highway revs up a bit - mine revs at 3100rpm at 100km in 5th, compared to 2700 rpm std.

After exhaust and more boost, I'd look at getting the power to the ground.

Good tyres

Good alignment

Clutch/flywheel

Suspension setup for drags (pineapples etc)

Mechanical diif (2 way etc)

And as dAVE said, higher final ratio.

And lot's and lot's of practice.....

You may not need to do all these things to beat a WRX, but hay, why not :)

All you really need is some aftermarket management I reckon. A Super AFC or preferably a Power FC should give you that bit extra to get ahead in the 0-100. Just practice your launches. It's easier to launch a Skyline than a WRX (assuming they aren't doing a clutch dump - and if I owned a rex, I'd be taking care of my gearbox) as you can get some wheelspin to stop bogging off the line, and they can't.

You just need to get off the line better...

Pineapples...

Adjustable rear upper arms...

maybe bigger rubber rear but you could just try really good rubber first...

good clutch...lighten the flywheel while your changing it...

Maybe a mechanical diff if you're really serious or lock it if your too serious.

You may need more power but even iof you do later, you will still need these mods to get the power down effectively, they are cheap (relativly to some of the engine mods suggested above) and will get you off the line like a rocket...

I think you would be surprised at the difference this would make.

cheers

If you have enough power is it actually better to have longer gears so you dont waste time changing gears....ie you have enough power to spin the wheels way too much all through second and into third anyway...

If you had a very low ratio diff like a 5.1 it would technically accelerate faster in gear but you might have to be in third to get to 100km/h...wasting time changing gears and much wheel spin...if you had a 3.9 or a 3.7 you might just make it to 100km/h in first??

You have to have enough power though...

Not too sure

Get a set of wide normal profile soft sidewalled tyres.

I.e Simex in a 225 50' 16" grip on my car very well. I can launch with them up around the 4500rpm mark with bugger all wheel spin. Simex are cheap, not rotational and spin like hell in the wet, a very dangerous tyre in the wet. I almost lost it by ever so slightly coming on to high boost in third gear at a low rev.

For a decent amount of sidewall flex, so that the tyres is flattened out on to the road when you launch you need at least a width of 4 fingers. Side wall width that is. :)

It is pretty difficult to beat a WRX off the line.. Even GTR's have trouble.. WRX's are full time 4wd that is why they break so many gearboxes.

      gauge needle removal

      I can say to anyone thats doing this; having done a number of R clusters; just be careful if its an unknown cluster.  It takes a bit of force to pull up; but if it feels excessive then its probably stuck. I've had this and pulled the entire hair spring out; and I can tell you; its not easy getting the correct spring replacement with the correct inner diameter and winding. In my case someone had used some sort of adhesive to stick it to the spindle and it pulled the whole spindle out; which the force seperated the hairspring from the spindal and caused it to deform.  You may have to clean it (IPA); or in my case if i'd known i should have used some sort of solvent on it.  Also check out Cruizin Central on eBay. He does all sorts of dials; and you can email him with any custom designs you want. So if you want like certain logos etc...he'll send you a mock of what it will look like then you accept the order and he'll take care of the rest. Fantastic dials and he can do basically any design you want.

      R33 GTST Axles

      Have you confirmed its the actual axles? Also the wheel bearings that mount on the hubs to hold the axles wear out. I replaced mine as they got play in them. It sorted my play issue.

      R34 Speedo not working after manual swap

      By Jarsky · Posted

      Ive converted a few clusters for the R33 with 320km/h dials. On the back there are some pads which can be bridged or unbridged (using solder or wick braid) to calibrate it. There is one bridge which is for MPH <> KPH; and there are combinations of bridges to offset it. There is probably a diagram  For example; this is my conversion for a 180km/h dial to a 320km/h dial (I put custom GT-R dials on it with the GTS25t layout) If you have J2 soldered (assuming the S clusters have a similar config to the R clusters); you may need to remove that solder

      Back on topic 😉, these are some of the notable pages from the booklets that are supplied with each weekly parts update. I never knew the BNR32 test mule car had an S13 Silvia front end... *Edit: On closer inspection the test car still had the R32 body, but only the front end had Silvia panels etc.
