Latest Dyno R33 Auto

Very nice power output. Also my primary long term target & no doubt would hit 300 on a cooler day.

im not concerned at not hitting 300 in the slightest..

its only a matter of changing the boost up another 2 psi and i will be back up to 320rwkw

simple...

but i asked shaun for a strong everyday tune thats why we left it where it is now.

Yeah absolutely. 0.1KW extra is hardly gonna be noticeable when ur cruising the 'burbs. Right now I'd be very happy with 200KW, but of course that will only last so long....

anything past 260 rwkw's is next to useless with the auto anyway.

If i hit the go pedal in first as you come on boost it spins the wheels hits 7000rpm changes into second hits 7000 rpm changes into drive hits 7000 rpm then changes into overdrive...

1st gear to get any sort of traction i MUST stay below half throttle, second gear is about 2/3rd throttle so i cant really plant it until im doing over 100klms, then i back of at 110!

so whats the point?

maybee manual conversion ... but you might love auto and auto is tough box

Na its my wifes car and she prefers the auto...

Hmmm would a better suspension setup help with traction?? just a random thought...

Sounds like its time to buy a Stagea and transfer your mods across...now THAT would be quick!!

A little extra weight, but your traction issues would disappear

Nice result however...

You need to change the diff gears by the sounds of it,

mine did exactly the same with 4.11's, went to 3.45's and problem

solved, even with 370rwkw on shauns dyno.

cheers

hmm mines the standard r33 auto sedan so guessing 4.3's

where can i get somthing in the low 3 range? that would be heaps better.

what other diffs with 3 ? ratio will bolt into the r33 gtst?

cheers

[sky30]

Im pretty sure certain models of s13 silvias had either 3.7 or 3.9 diffs, not sure which was auto or manual.

so what did you get your 3.45 from?

[Cubes]

It appears to be a Darren thing.

They 'work' their missus car.

Darrens car is an R31.

[Madaz]

try pete from willal racing they have some lower gears arround sometimes

if you need phone number pm me

Theres defintly a 3.9 ratio you can get for the R200's, and i am pretty sure you can get 3.7's.

I think silvia autos had 4.44's and manuals had 4.11's, i'm no R200/180 guru though.

If you have 4.3's, that would be bloody horrible, 3.7's would be the pick of the bunch if you get them,

Mines a aus R31, so i just got the gears out of a vl.

cheers

The S13 180 SR20DET's manuals ran with 3.9's.

47 teeth ring gear, 12 teeth pinion.

The Q45 Infinity R200 VLSD runs a 3.7 ratio.

Whats also interesting is the Q45 run the same larger GTR 31spline GTR 6 bolt (1x6) axles.

so what are you telling me?

what do i need from a q45 infinity to run the 3.7 in my 33?

is it just the centre? or do i need to change axles etc.

thanks heaps for the info!

[Cubes]

You have a few choices...

1. Use your pumpkin, center, half shafts and axles.

Grab the crown and pinion from the Q45 lsd and drop them in to yours. You'll have to get the backlash etc setup so thats more $$.

2. Use the Q45 Pumpkin, q45 half shafts with a set of GTR axles.

Grab the whole pumpkin (from memory they run the same front pumpkin mounts as the R33) and bolt it in with a set of GTR axles and hubs for stronger arse end. Still more $$ but not wasted on setting up backlash but rather a set of nice fat splines.

3. Use the Q45 Pumpkin with your existing Axles and half shafts.

Grab the whole pumpkin, rip the center out, pull it apart and drop in the guts from your origional lsd (viscus hub, spider gears etc) and bolt it together and not have to worry about setting up the backlash as you haven't played with swapping the actual centers. 'Shouldn't' cost you any more than the cost of the q45 pumpkin.

Did you follow that last one? Not sure if I was too clear.

The idea of the last one is you need to swap the spider gears and vlsd hub around as the q45/gtr's run a bigger more spliney half shaft. Using your origional spider gears and viscus hub you can simply slide in your existing 5 bolt half shafts

Obviously with the usual R200 swaps you'll have to use the backplate off your existing diff.

You'll also have to double check the front mounts. I'm certian they looked the same as the 33 pumpkin.

Thats if you want to retain the vlsd. It should still be in fairly good nick.

[dangerman4]

thanks Joel

whats the story with 300 zx tt diff's

aren't they 3.4 ratio r200 diffs?

and any idea in adelaide where to find such pumpkins? lol

Darren

[Cubes]

The 300ZX diffs are an R230. 230mm so a 9" diff.

They are tough as but unfortunately they don't bolt up. The 300zx diff's from memory are a 3.69 ratio and run the same chunky axles as the gtr/q45's.

In the SA section there's a stickied wrecker listing.

http://www.skylinesaustralia.com/forums/in...howtopic=123889

Ring every wrecker and see what they can do a pumpkin for.

The going price is generally around the $250-$300 mark. 'SOME" absolutely rip people off.

A good example is D1 garage.. $500 for a GTR Pumpkin, another *won't name publicly* wants $500 for a VLSD S13 pumpkin. :S

So ring around, some may also be able to supply just the ring and pinion depending on which way you want to go.

You may be able to pick one up for cheaper over at www.nissansilvia.com, remember to double check the ratio either way.

Simply pop the rear cover off, on the crown wheel there should be stamped something along the lines of 47:12 with a few other numbers. Simply divide 47 by 12 to give you your ratio.
