Would depend on Launches, Auto vs Manual etc.

0-100 350z 6.1 seconds, NA Supra 6.5

Could be reasonably close I reckon. Manufacturer figures arent always spot on as shown by fifth gear. I've seen a NA supra crush a mates R33 GTST and a F6 so I reckon its a possibility.

This is an old reply but anyway..

I drive a stock xr6 turbo, its an auto so its faster than a manual. I cleaned up a stock supra tt on his best run and I ran a 13.8. Without a lot of work i don't see an NA supra beating an F6 which should be faster. Even an manual should run a similar time to mine.

actually manual xr6t's are consistently slower than the auto ones with equivalent power regardless of the driver, its common knowledge over on the xr forums. It takes a hell of a lot more power to get them down in the same time. Benefits including not dropping off boost, more favourable gear ratios, easier to launch all make them up to a full second ahead over an equivalent manual.

The cost to get a manual into the low 11s is waaaaaay more (5 figures territory) than getting a 6 speed auto to the same point which is relatively cheap. But thats a bit of a tangent from this topic anyway.

I'd love to do a high RPM awd launch like a GTR can ;)

of course getting the auto into the 11's will be easier, but that is a far cry from a stock car. maybe all the manual drivers over on the xr forums think that you have to double clutch them or something. and if you compare the 6 speed auto to the 4 speed you will find the 4 speed much slower due to less favourable gear ratios.

This will be my last post on this cos I dont want to hijack the thread any more. Mod for mod the auto (either 4 or 6 speed) is significantly faster than the manual 5 or 6 speed boxes. With the amount of guys that have tried i highly doubt its because of the driver, but you're welcome to join the forums and try to tell the guys over there that if you think you are right.

The 6 speed auto is pretty tricky to get a higher stall converter working in so the 4 speed actually stacks up well with a high stall. From a roll the 6 speed stands out much more.

If you want to continue this via PM thts fine but i suggest you do a bit more reading on the fords before trying to correct someone who has done all the reading. I'm not on here trying to correct you about skyline performance.

and because we all know that every single ford owner is on the forum, and that everything that is posted on a forum is 100% true and correct.....

just to clarify, i'm not saying that when you really start piling on the mods that the manual will be quicker over the 1/4 mile because i know it won't, but for a stock or mildly stock the manual will be just as quick or quicker. but yes, we have gotten off topic

Is this not something to do with the final drive ratio? I don't see how a slush box can be faster than the manual with a good driver...all other things being equal.

with all the torque that the falcons have it is hard to get them off the line cleanly as it is very easy to fry the tyres in the manual. the automatics are much easier to get off the line cleanly. i can tell you that it is easier to get an auto xr6t off the line than it is to get a manual non turbo older model falcon with much less power. but if you do nail it in the manual it will be fast. also in any auto it is much easier to be consistent

I'd be interested to see the finishing speeds then as that may reveal that it is all in the launch.

tony - building boost off the line helps in an auto but the other factor is the box itself. The 6 speed auto is way ahead of the average auto 'slush box', I'm a big manual fan so for me to actually buy an auto it had to be damn good. I dont think its much of a call to say that its one of if not the best auto in a reasonably priced (under 90k) performance car.

The 4 speeds that run decent times have usually been rebuilt and had a different stall converter installed.

Unless the car is a lag monster and you have slicks I am not sure that is going to make a difference?

I mean traction is the limiting factor for the launch on a regular street car right?

this can be done in a manual by stalling the car up on the handbrake

Guys what would a R33 GTS25 manual be comparable to performance wise, straight line performance that is. I've seen an auto one have trouble pulling away from a 1.8L Lancer.

um, i'm going to go with, SSS pulsar, manual v6 commodore (or straight 6 manual falcon) or maybe even a VRX lancer. now i know that a lot of people will post up saying how they can flog commodores, but most of them would be comparing a manual skyline to an auto commodore, which isn't really a fair fight.

Hey guys,

This may be useful:

I did a manual conversion in my R33 non turbo 2.5L and did some runs with my little bro sitting next to me with a stop watch.

I get 0-100 in about 9.4secs which I thought was slowish. (Though I was not launching properly, pretty much starting the car with no skidding and flooring it). I then realized that I could go faster skidding tyres to get off the mark, though I have not tried it as of yet.

All I had was a pod filter and heat shield with good platinum spark plugs. It has an RB30 box in there with worn bearings too.

0-65 in first :) and the rest in second...just hitting the red line in first so I thought that was rather high geared. Ratios would matter a lot also I would have thought.

Oh, and my engine has done about 230,000kms at the time so it is old but in good condition.

I think it needs a tune too? idling is a bit weird when warm. Rises to 2000 revs and then drops and sits at 1000-1100. I can even the the clutch out with no accelerator and it won't stall :laugh:

Considering all, I think it didn't do too bad really.

P.S.

Here is a great sight and seems interesting.

http://www.letstorquebhp.com/calculator.asp

It says my skyline should be doing around 0-100 in 7.4secs and a quarter in 15.8. I recon driven properly and a newer engine it would get close to that. Still a bit of grunt in them I think :D

Note: An N/A Supra is only running about 6.6 for 0-100 according to that site. Skyline not too far behind :( especially for a 2.5L as opposed. to a 3L.

I get weights of cars and power stats from here http://www.cars-directory.net/

Love to get my N/A Skyline to beat a Supra N/A LOL.

cheers

P.S.

I hope to slowly get some decent power out of a 2.5 N/A, there is lots I can do slowly. Anyone know a forum or place that talks about my ECU. Should I stick with this one when doing upgrades and get it re-tuned or do I have to get a new chip that can be re-tuned to match my upgrades like my extractors etc? I hear rumours that gts25's can't be remapped/tuned?

As you can see, I don't know a lot.

Well, I suppose .8 could be a long time. Never really had much experience, but thanks guys.

For weight/power ratios of the similar car years are:

1994 SZ 3L Supra: 1420kg with 225 Hp

1993 2.5L Skyline R33 GTS25: 1360kg with 190hp.

Unless my maths is wrong or real life is completely different to stats (thus possibly admitting a Supra is far better than a skyline), I should have not much problem attaining 20- 35 hp more from an N/A to equal a Supra.

LOL.

Weight for the NA Supra is 1460kg with 220-225hp. What you need to realise is that power:weight ratio isnt everything. Torque, gearing and driver skill all play a VERY important role.

Ignore driver skill, since we're comparing the cars as models (not two specific cars owned by two specific people). The rest I'd agree with, though.

Also, suspension design and weight distribution. Being able to get the car cleanly off the line can make up for minor power differences. As an example, all else being equal (e.g. power, torque, weight, tyres) a FI MR2 will run better 60' times than a FI Silvia and should therefore beat it to the trap.

NA, it might go the other way since a 2.0L would just bog in the MR car where the FR car would be able to get a little slip and keep the revs up.

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
