All things going right i am going to run a low 13 in my gf's S14 with ecu remap, 3"CES exhaust,pod filter&partion, 15psi boost,optimax or ultimate with octane booster!

Has run 13.75@102@willowbank (exhaust,pod&boost) but i am going to try retread slicks, ecu remap &tiny bit more boost plus it's auto!

4doorz from Queensland just ran a 12 in his black 4dr R33. It was a [email protected] with a 2.045 60ft time. Quite impressive considering the limited mods. Mods include FMIC, full 3in exhaust, Power FC, Pod filter with cold air box, 235/40 R18 Federal tyres at 25psi, DIY boost controller, Heavy Duty clutch. The rest is reportedly stock. Not a bad effort. I saw him run a 13.2 on the Wed night test and tune at Willowbank, then on the Saturday Test'n'Tune broke into the 12s. Not a bad effort. Not sure what boost he was running, he did tell me just can't remember.

Also ran [email protected], 1.988 60ft on the Saturday aswell.

I think a good result on such limited mods.

Geez the sau 1/4 times are a little slow! I would have though that with all the people on here someone would be doing a 11!

Don't get me wrong my sx only runs 13.75 but it's got stuff all mods. I mean I thought skylines were fast?? My mates auto 300zx with less mods than others in the list would be no3 on that list plus he ran more mph(116.5mph) with std turbos, std i/c's, std ecu other than speed cut removed & rev limiter 500rpm higher, 245/16 falken tyres grb & a few minor other mods. And this is in a heavy, unreliable, overheating piece of junk 300ZXTT !!!

You will find that their are alot more people in the 12's just that not everyone is aware of the thread or has PM'd me there details.

Also I think their is only 1 GTR that has his time posted. With afew more R's the times will drop into the 11-12's.

Hi guys, a few have asked questions, which I will try and answer....

When we go to the circuit I stick on a set of R tyres, Yoko A0323R's to be precise. While I have the car jacked up to change the wheels over, I crank on 1.5 degrees more negative camber (total 2.5 degrees) on the front. I also add 1.5 degrees to the rear (total 1.5 degrees). We use the Whiteline camber adjusting bushes for this, real easy.

The stabiliser bars are also adjustable, we run full soft on the rear for drags and the middle setting for circuit. Front we don't change much, unless the circuit is slippery raining or super grippy. So we basically tune the balance (oversteer/understeer) with the front bar. This is done while the car is jacket up changing the wheels. We use the Whiteline blade adjustable stabilisers bars for this, real easy.

Our shocks have adjustable bump and rebound rates, so all I do is add a bit more bump on the rear shock for the circuit. Rear rebound rate stays the same for drag or circuit as does the front bump and rebound. You guessed it we do this while it is jacked up as well.

I used to change the rear springs to harder ones for the circuit, but once we got over 600 bhp the softer (drag springs) power down better (less oversteer) and the shocks take care of the rest.

If we want to drift, I just whack the rear stabiliser bar on full hard, don't add any rear neg camber and back the front bar off to full soft and it slides like a 180.

I know it sounds like a lot of work, but it only takes a couple of minutes extra per wheel over compared to just changing the tyres. Jacking it up and removing the wheels is always the hard work, shame not to do more while it is up there.

Hope that adds to the thread and answered a few questions.

    • So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!
    • OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
    • OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers) Replacement of the Valve body (if you removed it) is the "reverse of assembly". Thread the electrical socket back up through the trans case, hold the valve body up and put in the bolts you removed, with the correct lengths in the correct locations Torque for the bolts in 8Nm only so I hope you have that torque wrench handy (it feels really loose). Plug the output speed sensor back in and clip the wiring into the 2 clips, replace the spring clip on the TCM socket and plug it back into the car loom. For the pan, the workshop manual states the following order: Again, the torque is 8Nm only.
    • One other thing to mention from my car before we reassemble and refill. Per that earlier diagram,   There should be 2x B length (40mm) and 6x C length (54mm). So I had incorrectly removed one extra bolt, which I assume was 40mm, but even so I have 4x B and 5x C.  Either, the factory made an assembly error (very unlikely), or someone had been in there before me. I vote for the latter because the TCM part number doesn't match my build date, I suspect the TCM was changed under warranty. This indeed led to much unbolting, rebolting, checking, measuring and swearing under the car.... In the end I left out 1x B bolt and put in a 54mm M6 bolt I already had to make sure it was all correct
    • A couple of notes about the TCM. Firstly, it is integrated into the valve body. If you need to replace the TCM for any reason you are following the procedure above The seppos say these fail all the time. I haven't seen or heard of one on here or locally, but that doesn't mean it can't happen. Finally, Ecutek are now offering tuning for the 7 speed TCM. It is basically like ECU tuning in that you have to buy a license for the computer, and then known parameters can be reset. This is all very new and at the moment they are focussing on more aggressive gear holding in sports or sports+ mode, 2 gear launches for drag racing etc. It doesn't seem to affect shift speed like you can on some transmissions. Importantly for me, by having controllable shift points you can now raise the shift point as well as the ECU rev limit, together allowing it to rev a little higher when that is useful. In manual mode, my car shifts up automatically regardless of what I do which is good (because I don't have to worry about it) but bad (because I can't choose to rev a little higher when convenient).  TCMs can only be tuned from late 2016 onwards, and mine is apparently not one of those although the car build date was August 2016 (presumably a batch of ADM cars were done together, so this will probably be the situation for most ADM cars). No idea about JDM cars, and I'm looking into importing a later model valve body I can swap in. This is the top of my TCM A couple of numbers but no part number. Amayama can't find my specific car but it does say the following for Asia-RHD (interestingly, all out of stock....): So it looks like programable TCM are probably post September 2018 for "Asia RHD". When I read my part number out from Ecutek it was 31705-75X6D which did not match Amayama for my build date (Aug-2016)
