Guys, have a problem here..just need some advice..i have been waiting since June for a nice japanese performance car...i was choosing between the R33 GTS25T and the S15 JDM...right now the JDM is taking ages to come from japan. Firstly, the JDM is going to be really cheap because i am getting it from a friend in Japan who owns the JDM..however it is still going to cost more than a R33 plus i will not be able to test drive it...

I didn't want the skyline because i thought they are pretty old and might have problems...but right now..i feel that i really need a car fast because it is very inconvenient...Can someone tell me in what ways are the R33 GTS25T S2 better than the JDM S15? Thanks! please don't --> :flamer:

It's much bigger inside. Outside is bigger too (reads wheel base wider). More weight. Therefore more stability on the freeway etc. I have had the pleasure of semi owning both cars and i'd say they are both very nice cars.

If you get a nice sII r33 that is in good condition, you most likely won't run into problems. So many people own r32s and don't have too many problems.

well lastly it all comes down to power...the S15 is much lighter than skylines..but skylines if i'm not wrong has more power stock than the S15..i know this topic might have been covered before, i dunno how to use the search option...:P Is R33GTST faster than S15?

unless you get a R33 with a sunroof, autotrust on the forums owns an R33 GTSt 4 door with a sunroof, and he's around the 6'4" mark and he's constantly complaining about not being able to spike his hair, neck problems etc

I have an R33 Gts-t and my mate has a Aus S15 so when mine was stock, it was faster but your JSpec one will be faster than a stock Gts-t.

His does feel a lot lighter to drive though although less stable at high speeds. He commented how it started shaking a bit when he took it up to 180km/h and felt a little unstable whereas my 1994 R33 pulls over 200km/h without shaking one bit.

I'm a very conservative driver so there's no way I'd take my car that fast unless I felt completely safe doing so, and I do.

However, if I had the choice of car, I would go for the S15 hands down. Far far newer, and once you start modifying, from what I have heard it will be faster as well. Although you pay about 10k extra.

Keep in mind that if you're going to be modifying this car then the power advantage of JSpec over Aus S15 will not matter as the restrictive parts in the Aus S15 will be removed leaving you with pretty much the same car (Jap/Aus).

the bad part about S15 is that it's pretty small..i'm a tall bloke at 6ft 4...i think the skyline fits me better...

Im 6ft 3 and have a r33 no sunroof, sunroofs will give you less headroom mate. I cant fit comfortly into a 32 but my 33 is fine. I have sat in a S15 (no sunroof)at the melbourne motor show a couple of years ago and I fitted fine because the seats seem to be a lot lower in the silvias.

Both have the about the same power stock so the s15 is a bit quicker due to weight. Id test drive both cars if you can mate then make your desision.

I see the skyline as a grand tourer andt he silvia as a sports car

:P

I was in a mates Spec-R yesterday - I'm 6'0" and found the sunroof *just* low enough to be a pain. It was enough to turn me off one right away. I'd recommend finding one in a dealership and having a test 'sit' to see if it works for you.

Other than that, the S15 looked beautiful. Very modern inside, if you can fit inside, you'll love it. Performance is much of a muchness - choose the car you like then modify the engine/susp/whatever until it drives and performs how you like.

what's a grand tourer??? i always see people using that phrase...

A grand tourer is more of a luxury sports car, rather than an all-out racer. The best term I've ever heard used for it is "gentleman's sports car". Something that's swift and enjoyable to drive in ways that your average family hack aren't, but not as visceral as a dedicated sports racer.

Think about what Jaguar and Aston Martin offer. Or the larger Ferraris (456, 550/575, etc). They're not cars you'd go attacking touge in, but if you're on a country road with lots of sweepers you can carry a fair amount of speed through them while still having a plush interior with all the creature comforts, good NVH, etc.

As such, they tend to be a bit larger. This gives them stability at higher speeds and in open flowing corners, as well as more interior room.

In that class, you'd have vehicles on the sportier end of comfort (like Skylines) or the more comfortable end of sporty (like Soarers), they're still a more enjoyable drive than a Maxima or Camry. But if you're carving through a set of hairpins cut in to the side of a mountain, you're not likely to keep up with the sporty and nimble, but far less comfortable, Silvias, MR2s and Integra Type-Rs.

The R33 will be a roomier car. It'll have more space, and it should be more comfortable. The S15 gets quite cramped, especially up back.

If going at high speeds is your thing, the R33 will be more stable. The question is how often you're planning on hitting 160km/hr+. I've driven an S15 at freeway speeds and the car's fine.

I find the S15 suspension a little firmer than the R33s I've been in (stock in both cases). Depending on your requirements from a vehicle, this might matter. On less than perfect surfaces, the R33 does a better job of keeping the tyres in contact with the ground while not causing you pain.

well said mate:cheers:

I originally was after a S14 but opted out due to me not being able to fit comfortably in one. I'm around 6". Having said that, the S14 had a sunroof which was probably the issue, however they still feel quite cramped, i'd hate to have a crash in one....

The R33 is nice and comfortable to sit in, more room up front as ppl say (the back is still useless). I've heard that the S15 has a "cheap" interior which rattles to shit, and that the 6sp box isn't that great.

The S15 interior looks nice, but I've found it maks easily. Most of the S15s I've seen have scratches or scuffs around the shifter area, just from normal wear and tear.

The 6 speed box is OK, but it has some known issues with breaking a circlip and rendering 5th gear? (can't remember which one, but its a high gear). Since its also the same physical size as the older 'boxes, but with an extra gear, there's also less room for oil and so it does suffer more heat issues under sustained load.

    • Bit of an update to this one. Having some issues on the dyno that held us back (boost spiking) and I want to pass some info over you guys and see what you think is wrong with my setup. The current readout on this dyno is 462rwkw on a low reading dyno so keep in mind it is a real world 500rwkw setup on a hub dyno. Don't read into the power figure too much as a sign of the issue. The short and curly of it is: 2.8 Litre Racepace build RB25 NEO N/A Head with VCT (internally standard however ) Borgwarner EFR 8474  Turbosmart 50mm Straight Gate + Mac valve 6Boost Manifold 4" dump to full 4" exhaust (nil restrictions) Wastegate plumbed back in and all angles in the exhaust system are acceptable and not too sharp. GFB SV52 BOV in cooler piping  Turbosmart BOV in EFR Housing   The issue we are having is it comes onto full boost for example at 4000rpm and spikes to 24/25psi, before dropping down to 17psi before slowly rising back up to the target boost of 23psi. It was extremely uncontrollable and the tuner actually had to ramp in boost progrssively with each 1000rpm on each boost setting we selected to try and reduce the amount of spiking. Sometimes we would see a drop of 10psi from the peak at the beginning of the run, to the low, until it took the next 500-1000rpm to stabilise back up to the target boost. The tuner is pretty confident that the straight gate is just a poorly designed product and leaks too much boost upon cracking the gate open and theres no way to fix it other than going to a poppet valve. He's also confient theres no ignition breakdown or floating valves. The fueling is extremely stable as well. Turbo speed is somewhere around the 109,000rpm area. The spanner in the works for me is that prior to this Borgwarner and StraightGate, the car was tuned on -5 twins at a diferent tuner, and he also had issues controlling the boost with it spiking around the same rpm range, so to me this sounds like the same issue and it can't be anything on the turbo side as this was all changed and I think the behaviour is extremely similar, if not the same. We also removed the mac valve and did a run on wastegate pressure and it still spiked and had the same behaviour. My thoughts on possibilities are: Boost Leak VCT Cam Gear isn't reliably activating consistently - (On this however, we did a run with the VCT disabled and the boost still spiked) Turbosmart BOV is not handling the boost? However this seems unlikely to not be able to handle 20psi. I have a couple of logs that I can't make sense of if anybody knows how to read them and can obtain further logs of other parameters if they are not enough, happy to pay for anyones time. The dyno readout with the power figure is the most recent last week. The other picture is from two weeks prior to that where we couldn't break 400kw (we removed the cat), however the issue of the boost control persisted. @Lithium @Piggaz @burn4005 @GTSBoy @discopotato03 I've tagged those that were quite active in recent pages here, no disrespect to those that know turbos well but I missed tagging. Cheers 
    • I recently purchased a 2018 Infiniti Q60, which has an SD card navigation map. I can see my system has options for real time traffic updates etc, and am wondering if there is something I can purchase to get this working? I can see there are at least updated maps for USA and Canada, but nothing for Australia. Surely Infiniti took changing road systems and city expansions into account when they decided to use an inbuilt navigation over Android Auto/Apple Car Play, or are we doomed to drive on streets that don't exist in the navigation system if you drive to a new area?
    • Luckily I didn't put in etch primer as I just found out it's not compatible with my body filler lol. Also just need to sand the panel anywhere between 150-400 grit so I'm in the clear there. It does say to not apply to soft old paint, I assume that means paint that is flaking, peeling,etc
    • @dbm7 and @GTSBoy thank you both very much! will give that a shot!
