just took my Soarer out for a quick blat and photo shoot and thought I would test 0-100 kmp/h times and got consistent low 8's only mod is BFI does this sound right bear in mind it was also pretty hot so I'm sure this could be improved with colder weather and also I'm still getting used to the auto box and I'm Probably not getting the most efficient take off basically just mashing it in drive from standstill. would probably get better launch if I got the revs up then slammed it into gear but I'm not keen to try that without some feed back on better launch technics ? what do you guys think ?

Do not rev then slam into gear! Unless you like breaking things.

Warm the car up, do an ECU reset, do some mash to the floor starts - just to 60-80kph is good enough. Briefly remove your air filter, then do some times runs. For best results, squeeze the pedal to about 1/2 way down, then as the car gets going, press all the way down. Don't forget to put the air filter back in, and you can then do another test and see if it was any slower - which could mean you need to replace the filter.

cheers Pete this is exactly why I didn't want to try slamming it into gear as I was sure there would be someone on hear who would know how to get the best out of these Auto's. Just for the record I don't like breaking things =) P.S my air filter is in good nick. will do the ECU reset as I don't know if it has been done at all on this girl. basically I was just wondering if the times were on par with what a UZZ31 should be doing and from the sounds of it it's not bad for a warm weather run ?

Haha to the suggested shifting method.

8 Seconds is probably about right, you have to remember the age of the car is how 19 years.

So naturally things are not going to be performing at their peak unless you replace or rebuild them.

However, my Soarer V8's all were good for low 7's to 100 and with a few modification 6.5 or so, the Celsior more in the 8 second bracket, these were all very tidy cars however which makes a difference.

The only way to get the most out of the auto is to bin it and get a W58 manual fitted. :-)

yeah Mike for sure I just lack the coin for that sort of conversion at the moment and would probably spend it on a supercharger if I did have it first. I also think I would get better times if I had cooler weather and also still to try ECU reset and slightly different launching technic as suggested by Pete should see me into the 7's I think my car is in very good condition and has been very well maintained one of probably only a few I'm Sure.

how are you measuring the times?

video and stopwatch van be very inaccurate

i have a gtech pro you could use but your in NZ lol

mine 100% stock was around 8.4

then with catback average 8.2 sec... they are pretty sluggish off the line

since unplugged the maf and it's around 7.8sec IF.... if it shifts reasonably, there is a trick to it with the maf unplugged as it retards the timing big time on the shifts, but all the time is made up in the 0-50km/h range, where as before stalling it up a few rpm would make no difference and it was quicker to just stand on the go pedal now it will spin the 265s off the line.... i though it went pretty good untill i got my new car though lol

A cheap way to get better acceleration is to replace the Diff with a shorter ratio so go to a TT diff, they are 4.08 I think so a bit better for off the line acceleration.

Jesus, my lowley JZZ31 manages a pretty consistent mid to low 8's! I guess they really are getting tired now.

I'd say check compression, if thats good there is no reason why you should't get some good performance out of it. Clean & test injectors, replace plugs, test/replace HT leads, inspect/replace distributor caps and rotors, test/replace coils, flush transmission with T-IV, drain and replace diff oil, flush power steering, replace air filter, oil filter, (use quality oil), fuel filter etc. Remove or replace cats (they will be rooted by now) - even better fit a new exhaust.

These are all the jobs that typically never get done on NZ cars and many of them sap performance significantly, especially one on top of the other.

I guess it'll never be quite as quick as a good UZZ30 because of the weight difference, but it does sound like its struggling a bit?

G tech timing and I thought low 8's was pretty good considering the weather and my lack of auto launch experience ? also being a UZZ31 being a little overweight ? I'm pretty sure i could get a better launch out of it once reset ECU and try different launch technic as has already been recommended.

Mike: I am on the look out for a tt diff for it's limited slip abilities but waiting for one at the right price

Well my 3.0GT Soarer like Matts could do high 7's on the GT2 timer I had when doing a good start, but with ease in the low 8's

You should do a dyno run, see what sort of power yours is making, If its under 125rwkw then it is under performing, ideally you would be wanting between 130-140rwkw from a stock car.

Yeah Diffs... often hard to find at a reasonable price. Often over priced and have an unknown history.

Well here's one:
http://www.trademe.co.nz/Trade-Me-Motors/Car-parts-accessories/Toyota/Diffs-axles/auction-273805393. htm

I would expect some sort of guarantee, installation and new diff oil for that price.
It's in your area too Daniel. Go see them and haggle.

Yeah, the TT sixes are more around 6 sec or so to 100. Fast bastards, but they are not a V8 hence why I never bought one!

Turbo inline sixes are too common for my taste.

I have a 31 Daniel, and on a slow run I get about 7.2-7.5.
Best was 5 seconds flat.
When I can next do it, I will post a video.
However, your ecu needs a reset. Do that and your times will drop.
Make sure you do it properly

Wow, fairly pricey Evan.

I nearly got a wrecked TT with big brakes and a TT LSD all for $800 a couple of years ago, but I just missed the sale by one day.

Quite unfortunate.

Yeah it is pricey.

If it doesn't sell he may drop the price.

If it does sell I might consider pulling the factory LSD out of the TT, selling it for a similar price, and then puling the JZA80 LSD out of the 31, put that in the TT and then putting the original 31 open diff back in.
Then I could use the cash to buy a TRD centre
and put that in the spare JZA80 weld diff that seems to be kickin around the workshop.
But then, I should just get my ar$e into gear and put the 1jz back in the TT.

Joe I find it hard to believe you could get 5 seconds flat acceleration out of a UZZ, thats faster than a twin turbo. Unless yours was heavily modified?

It would have to be supercharged to get that on a flat road.

have dealt with empire imports before and they are rip off merchants charging huge prices for second hand gear with unknown history. for that price I would go for a new genuine TRD center but that's out of my budget at the moment so I'm on the look out for a second hand one but I'm not paying that sort of coin for one !

Empire imports are okay, they will negotiate on price.

That price of $1400 from Bond on trademe is for a brand new centre only. Then you still need to get the 4.08 gear and swap it over.

I would pay around 1k for a used 4.08 Torsen. These are pretty reliable. Not too many get broken so milage isn't an issue.

over a grand is too much to pay for a second hand diff in any case I would expect $800ish and I have not had great feed back about empire nor personal satisfaction from them I was quoted $200 for a small orange indicator for the front bumper that I subsequently bought on Trade me the next day for $25.00 from another seller the only reason the price was so high I can assume is because it is essential for WOF this is not great way to attract new customers.

It sounds crazy doesn't it. I wouldn't believe me either, except I saw it. I've done it three times, largely stock motor and car.
But seriously, I have no proof, wait until I put up a video before you make up your mind fully.

Best I ever got out of my UZZ30 was around 6.5, with a good tailwind on a very good piece of road, and it was a very good motor compared to some of the others I've driven.

You'd have to be driving down a cliff to get a 5 I would think!
