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 :P

I've never driven an R33, but I just so happen to have an R34 GT-T Tiptronic :P 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 :P 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?

Yes, mine is four door, and the tiptronic is a whole lot of fun

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 :P

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 :P

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 :P ).

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. :)

  • 1 year later...

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 :O 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?

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!

    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment. 
    • I was able to get some underside photos while the car was on the ramp The suspension is all Altezza/IS200/IS300 so getting part's will hopefully be less of a headache
    • Welcome to my 2004 Toyota Mark ii IR-V Fortuna (series 2) With a 1JZ-GTE powerplant under the bonnet (hood) it'll give me plenty of scope for power upgrades. For those who aren't familiar with imports, the 1JZ-GTE is a 2.5L 6 cylinder VVTi engine with a single turbocharger. This has the factory R154 5 speed gearbox, along with a aftermarket 2 way LSD differential (brand unknown). Under the arches are a set of CST Zero 1 alloys, 18x9 +30 225/40 up front and 18x9.5 +15 265/35 on the rear. The car was quite low in Japan and there's evidence of the wheels catching the rolled arches/fenders. The tyre's aren't great so I'm in two minds whether to replace both or just the tyres and put up with the wider wheels on the rear. The car still uses stock brakes with the addition of some braided hoses. The exterior is stock with the exception of a BN Sports front bumper and a replacement Fortuna grill  Moving to the interior, the steering wheel has been replaced with a dished MOMO steering wheel (which will get swapped for my Momo Tuner for the time being) Defi Link Gauges are mounted above the climate controls and on the A pillar, the Oil Temp,Oil Pressure,Water Temp and Boost gauges should help with spirited and track driving  The stock seats have been replaced with some retrimmed Recaro bucket seats. Being a larger build these are a little snug, unfortunately the orange isn't for me so I'll look into replacing these down the line. Other modifications include a twin plate clutch, Blitz intercooler, Evolve alloy radiator, a stainless exhaust with decat, HKS EVC-S boost controller and coil overs
    • Apologies for the long read My R34 GTT was up for sale at the beginning of spring due to a few repairs creeping up. The strut tops needed replacing, roof and bonnet (hood) painting (yay for 3 stage pearl) and the underside stripped and treated. I sold the car which allowed me to be in a much better place financially. Leading up to the sale I was already thinking about the replacement. In an ideal world it needed to be a good all-rounder. Something I can mess around with, modify, do track days, do the school run, go on long drives etc.  Options included but not limited to... Laurel C35, Evo 8/9, Civic FD2, Impreza Hawkeye, Aristo and even an Audi S4 Avant (I've already got the Mazda 6 wagon). But there was always one car at the top of the list The Toyota Mark ii JZX110 I found an advert on a Facebook group for an example in Japan, from a seller called Jon at Rising Sun Exports. A few messages back and forth and Jon calls me from Yokohama one morning (or afternoon in his case). He briefly explained the import process, the costs involved and a repeat of the advert. After much deliberation, the price was agreed and the sale was locked in. I've never imported a vehicle so I jumped into the unknown head first. The money transfer was completed through wise.com (fees apply), very easy to use and the money was with him within a day or two.  The car suspension was raised for the vessel and the car dropped off at the port. It was 7 weeks later when the bill of lading was received and the freight invoice sent to me, followed by the export certificate a couple of days after (both digital copies) In the mean time the port had been in contact. I needed an agent to deal with the NOVA (notification of vehicle arrival) along with the tax/duty invoice, this was £75.00. The port also had a fee of £100, I'm guessing to cover the cost of the 10 day 'free storage' and for moving the car off the boat etc. They need a copy of the vehicle invoice, freight invoice and export certificate to allow the vehicle to pass through customs. The vessel arrived on Tuesday 5th August, the tax/duty invoice was generated and sent over. This is generally tax 20% and duty 10% of the vehicle value. Although the invoice came in at a higher amount than I had calculated. Once HMRC had received the payment the vehicle could be released from customs. I thought once the tax/duty was paid you could collect at any point, that's not the case. Your agent will need to book a collection slot, I requested Thursday 7th which was accepted, with a 9:00am slot allocated. It was a 5:00am start from Norfolk heading to Southampton. We eventually found the compound, upon presenting the bill of lading and some ID they released the car (they drove it out of the compound to the front ready for us to load up). The email from the port stated each slot had a 10 minute window, which seemed abit farfetched but the staff said it's not a strict rule. We were there for approx. 30-40 mins in total. A week prior to collecting I contacted my garage and explained the situation, I was able to get an inspection slot that afternoon. For the registration, DVLA require the car to be insured, for this I used a company called Adrian Flux who can insure the vehicle using the VIN number. 
    • Hey guys, looking for these side skirts if anyone can help me out.
