R33 GTS25t Auto Vs R34 GT-T Auto?

[Myth33]

Ok I am currently buying an R34 (r34GT-T on its way from Japan) and as some people here have noticed I am selling my R33 GTS25t in this forum as well. In this thread I am really hoping some people can tell me how different the two cars drive?

(here is the link if you are interested in my R33- http://www.skylinesaustralia.com/forums/sh...167#post1234167 )

I believe the specs on my 1994 GTS25t 4 Door are around 187Kw (correct me if I am wrong) and the 1998 GTT also 4 Door is around 206Kw.

POWER TO WEIGHT RATIOS:

R34 GTT 4 Door - AUTO Tip-Tronic 1450 Kg Weight / 206Kw = 7.03Kg per 1Kw

R33 GTS25t 4 Door -AUTO 1380 Kg / 187Kw = 7.37Kg per 1Kw

By these figures the 34 GTT has only a slight power to weight advantage. So how much quicker is it really? Does it feel much quicker or does the Tip-tronic trans give it a notable advantage over the R33 equivelant?

Any opinions on this is greatly appreciated

You'll notice the difference when cornering.

I am asuming you are talking about the R34 being a better cornering machine? Oh no.... please dont' tell me that there is little to no difference in straight line performance .

I've never driven an R33, but I just so happen to have an R34 GT-T Tiptronic While I can't comment about the difference in performance between the two, I can tell you the tiptronic makes a big difference over the auto, I get much better pickup and response by choosing the gears myself then by letting the auto do it.

Other than the R34 having a more advanced auto box (helping snappier gear changes).. and slightly newer engine otherwise I would have though they would have been very similar in most situations. They both run a 2.5L, with the Neo version having a small few enhancements.

The R34 seems to respond better to the usual modifications in terms of power. 1/4 mile times are very similar though from what I've seen mod for mod compared to R33.

So it sounds like the Tip-Tronic is not just a gimmic that I'll never use! Cool Thanks for that Firefrog. Is yours a 4 Door? Does there feel like there is turbo lag at all?

My GTS25t feels like a N.a. car until about 3,500 rpm where it starts to build up steam and by about 4,500 rpm the car is boosting fairly hard and this continues through to the redline.

Like I said On-paper stats, can't tell a person like me who hasn't driven the car much at all. On-paper stats as we all know can be distorted (take the GTRs' On-paper power for example). Also On-paper the r34 GTT is has the same power as the GTR but we all know that is incorrect.

Can anyone confirm the power to weight figures that I worked off, or does anyone have standard 400m or 0-100 times for these two cars?

[Firefrog]

Yes, mine is four door, and the tiptronic is a whole lot of fun I've never driven a turbo car before, so I don't really notice the lag an incredible lot, although how you describe it sounds about right.

[Myth33]

Awesome a 98 4 door GTT, exactly what I've got comin! I noticed you live in Brissy too, gee I'd love to check out your car if you ever had some spare time or anything, it would be good not only to check out what I'm in for but also to compare with my existing R33, if your up for it let me know (btw I live southside).

The Tip-Tronic sure sounds like a quality item anyway

Well I'll be going down BWCP tomorrow night (sat), so if you wanna have a look/ride/drag send me a PM and I'll give you my mobile and we can sort something out

[Myth33]

Firefrog you have a PM

[Myth33]

Well firstly I must say thank you to Firefrog for giving me the opportunity to check out every aspect of his R34 GTT 4 Door. It was great to ride in your car and feel all that it had to offer (which is a lot btw ).

For those of you who are interested in how the 33 and 34 4 Door Auto's (turbo)compare in a real head to head comparison read on.

Here is my opinion.

In a one on one line up from stand still there is not much in it at all. We are talking not even half a cars length between us. Things to consider in this test run, my 33 has a 3" mandrel with dump as the only performance mod, the 34GTT was stock as a rock (performance wise). Also with no malice intended, Firefrog was still learning the best way to launch his car with not owning it for more than a couple of weeks, where as I had had my 33 launch down to as good as I can get it (after about a year worth of owning/driving it). Still it was neck in neck in that short run. On a longer stretch of road the 34 would consistently pull away slowly.

On the motorway we dropped it while rolling. Here the R34 demonstrates its superior tip-tronic box and top end grunt, slowly edging away further and further. It wasn't blow you out of the water difference but yes there is definate, real world improvements over the 33 (and remember mine had the exhaust modded as well).

I was most impressed with the 34 at the end of the night when Firefrog was nice enough to take me for a drive inside it. The very first thing you will notice hoping out of a 33 and into a 34 is the seats! The Seats hug you like a racing bucket yet still have a nice level of plushness. The Torque is truely an upgrade. The push you feel that keeps you back in your seat when the car accelerates, is without question stonger. But last and certainly not least the handling is superior in every aspect. The car has significantly less body roll and feels very up to the task compared to the 33 when it comes to the twisty stuff.

Now for a couple of comments on this Tip-tronic Box. I can't compare it against the manual in the 34 because I haven't been in one, however I've been in some nice euro cars with tip-tronic. The R34's Tip-tronic is a real gem. It is smooth and takes no-prisoners. From first gear it accelerates with easy to the Redline where you hit the next gear, it has a very brief moment as it finds the next gear to continue accelerating, but it is brief and not much different in my mind to the time it would take for a fast manual gear change, Yes VERY NICE! Infact the tip-tronic box felt like it could do it all day, every day it was that unfussed about using it manually. The change is also whisper quiet and there is absolutely no hint of shudder or harshness in the change. Nissan had obviously spent some time making sure the Tip-tronic was well integrated in the car.

Not considerng many other asthetic and functional advantages of the 34, it is a hell of a ride, although there is no question that both cars are great performers the 34 just feels more purposeful, sporty and overall stronger. Given though there is a big price difference in these two cars (approximately an extra $15,000 give or take between them) so for the money you would expect that the 34 has these improvements.

Thanks again Firefrog for giving me the opportunity to experience your ride, nice. looking foward to our future trips together.

Great write up Myth33, Tip-tronic is a real treat in the R34's

[paulsid]

Hey guys I have owned an R34 tiptronic 4 door for just on 2-3 weeks.

Although I have always driven manual turbo vehicles, the tiptronic is a pleasant change for now. I must say the car definatley picks up the pace much faster when using tiptronic as opposed to just planting the foot in auto mode.

Overall I think its a great car begging for more money to be spent on it ;-(

My biggest dissapointment in this whole equation approximately 300ks out of a tank for relatively easy driving out of a late model 2.5 litre!

I will be looking into better oil and plugs hoping to get some more k's out of the tank.

Also keen to find out what R33 parts if any can be used on the R34. eg pod filters, intercooler, exhaust etc.

My biggest challenge at the moment is trying to source stylish but tough looking aero parts at a half decent price..

Anyway look forward to reading your thoughts.

Out of curiosity how much did you guys pay for your R34? roughly? As I have seen them from 24-30K so dont know what the real market value is on a good condition one that is...

Mmm interesting read for a Thursday morning Well done on the write up, you've pretty much covered all corners (I think).

Anyways, here are a few of my own opinions; I also have a R34GTT auto, only it's the coupe version.

1) The R34GTT is a vast upgrade over the R33GTST; everything from engine to suspension to interior/exterior trim has been upgraded. It would be false to say that there is close to nothing between the two cars. Saying that, the RB25DET in the R33 is a NOT the same as the NEO RB25DET. You will find that once you begin to mod, a lot of the standard things you can do to the non-NEO will not work on the NEO engine.

2) The auto box with tip-tronic selector is a great way to a) get more power quickly, b) have a bit more control over the car and c) have more fun. Even in its stock form, the tip-tronic gearbox is very responsive provided that the ECU does not "prevent" you from changing gears.

Believe me, there has been many times when the ECU has just stood up and said NO to a up shift or down shift. However, this can be sorted with only a few simple modifications.

3) When you guys say that the tip-tronic gearbox gives you better acceleration etc etc. I used to believe this too but have come to discover that simply planting it in D gives a better result. If you don't believe me, feel free to try it out.

The one thing you will notice is that your boost will not drop off with each gear change, and you will be able to take your car to redline before it automatically shifts (don't be scared that you'll just bounce off rev-limiter) it will shift!

Anyhow, I'm sure you'll all come to your own conclusions about the auto in due course - it's been a very fast and steep learning curve for me personally. So many things you can do, so many things you can't do which adds to the challenge and learning experience in my opinion.

It'll be interesting to hear what some of your end-goals are for your cars - mine is to build a 300rwkw street-response machine. It will mean that it will be average on the track but unstoppable on the street which is OK as that is where I am most of the time.

Good to see great reviews by the fellow auto lovers...

A question for R33 GTST drivers: When trying to get the best launch of the line should you use the power mode and plant the foot down or? Also I believe there is a "hold gears" button as well... do you use that too?

[n15m0]

Anyone notice that this thread is a year old now?? Nevertheless a good read for those that have just come along. FYI, not long after the above was written, Myth has been the proud owner of a 4 Dr GTT for the past year.

[paulsid]

OOPs well it was quite late when I found the thread.. oh well..

My goal is to mod the car without too much compromise on;

1. consumption when not planting the foot

2. Pocket - lets not forget that money spent on cars never comes back! So affordable mods and second hand parts where suitable are desirable.

3. Reliability

4. Maintain my license!
