give jms a ring they faxed me a quote about 3 weeks ago gearbox was $1700 and all the other little bits was about $525 and $50 for freight... So you're looking at $2275 just for parts so with labour you'd be looking easy $3000....Or you give Yarra Valley Automatics a ring and you can have ur auto strengthened with 2800rpm stall converter with an auto cooler all for $2500 which is including labour 3 day job aswell and if u take ur car down the quarter mile u'll get better times than if u had a manual cause with man u gonna need a bit of practice before u expect good times, and going by the price I'd stick with the auto which is what'll be doing....

I had mine converted by Hills Motorsport earlier this year.

cost me about $2700 for parts (got a HD clutch which was $500) and another $1000 for labour.

was a much bigger job than they had expected, having only converted r32s in the past. Mine was the first r33 they'd done, and it turned out there were many more incompatible parts between auto and manual in 33s than 32s.

it took about 6 weeks for them to do the job, 5 weeks of which was waiting for parts.

before you get it done make sure they have converted EXACTLY your type of car before. Mark at Hills would be a good choice now that he's done one, but if I'd known he hadn't done an r33 I would have gone to someone else.

I heartily recommend doing it , it's MUCH more fun to drive now, even if it is a bit slower (i can't shift as fast as the auto...at least not all day every day)

I spoke to UAS , they quoted 3k drive in drive out which seemed to be quite good considering the cost of auto r33s in comparison to manuals . Also Im hoping that the autos probably were not as thrashed as the manuals .

I did this conversion to my 180sx and it went pretty well especially considering the front cut the manual came from had only done 40000ks so it was a pretty good box to start with .

Are there differences in the final diff ratios between the autos and manuals ?

Sorry top_secret but rs73 wanted to know this!

Final Drive Ratio

The reduction ratio of the transmission gear(differential) set furthest from the engine. In other words, the ratio of the number of rotations of the drive shaft for one rotation of a wheel. In general, a low final drive ratio results in better fuel efficiency, and higher final drive ratio results in better performance!!!

The ratio expresses the number of turns required by the pinion (which is attached to the output shaft of the transmission) to turn the drive axle one revolution, i.e. 2.73:1 means the pinion must turn 2.73 times to turn the drive axle once. A higher number means a lower (or shorter) gear. Short gearing gives quicker acceleration, but because the engine must turn faster, gas mileage and top speed are lower. Tall gears give better acceleration and higher top speed, at the expense of acceleration.

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
