Any one out there with an R32 or S13? You sick of the rear axle tramp on hard launches? Want better take off? OR How bout making the rear more predictable for drifting?

I HAVE YOUR ANSWER => PINEAPPLES

These are urethane rings that solid mount, and modify the angle of, your rear sub-frame. There are two methods of installation, GRIP and DRIFT. This modification to your car is completely reversable, can be changed between GRIP and DRIFT in around an hour or so, and greatly reduces axle tramping.

These 'PINEAPPLES' have been marketed by Japanese Motorsports in Adelaide for $150 for a while now. I have found a local source, and can supply them for $110 WITH ENGLISH INSTRUCTIONS.

I can also fit these to your car if your in the melbourne area.

PM me, E-Mail me at [email protected], or call me on 0411 878 961 if you are interested.

Nope, axle tramp is when you get wheel spin and your wheels and subframe 'bounce' a bit and cause major vibrations through your car. Of course bouncing wheels are not good for take off. If you need further explaination call me on 0411 878 961.

Doc,

Can you explain where and how they mount. I've seen the pineapples on JMS that your talking about, but I could never workout where and how they work.

Do they work like a shock absorber for your sub frame or something?

And how do you change them between grip and drift? Is it just locating them in a different part of the sub frame?

And the big question (and last - sorry :P ) are they legal???

Thanks

Ok, There's four main bolts that hold your subframe on. All of these bolts have rubber bushes in them that allow the entire rear sub-frame to move around. Pinapples reduce the movement of these bushes.

You can mount the pinapples either above or below the subframe to take up the movement. These particular ones are designed to mount diagonally opposite, IE Front Top & Rear Bottom OR Front Bottom & Rear Top.... When you take up the slack in this manner it will slightly rotate the entire rear subframe, and hence your lower control arms. I believe it is this change in angle of the lower control arms that gives you your different handling characteristics.

Switching them over is a simple matter of removing and refitting by the other method.

LEGALITY => I have no idea, and refuse to 'guess'. You would need to speak to an engieeer for approval. I would simply paint them black when fitted and plead ignorance if it becomes a problem.

J, Hope this helped your curiosity. The JMS instructions are in Japanese and difficult to interpret. Call me if you want to discuss? 0411 878 961

J,

What sort of car is it? Changing tyres wont help, I've tried it. Some of it is due to shockies but most is due to your subframe moving aroung.... Keep me posted if you want me to order a set.

Doc,

At the moment I'm running Sava Raptex's - I must say that they are the worst tyres I have ever run on ANY car !!! But when I got them I was strapped for cash and needed to go over the pits - I really can't complain as they cost me $93 each (225/50/16's) and I've got 12 months from them.

I'll be getting the Dunlop FM901's in the same size so I'm hoping for a massive increase in traction :P but as you said, I'm not sure if they will fix the axle tramp. The suspension is pretty tight in the back (which doesn't help).

I'll let you know how I go after the new tyres go on.

Thanks

Jayson

The car is a R33 GTS-t.

Dig this - just did the phone around to get some FM901's (225/50/16). Prices range from $200 each to $271 each!!!!

Apparently Dunlop have put their price up as of tomorrow, so for any store that needs to order them in they have to quote the higher (after increase) price !!!!

I've found a place that has them in stock so I'm hoping to get them before the weekend........

Sorry - that was a bit off topic - I was just shocked !!

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.

      Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
