gotta agree with u on that one man..but at the end of the day i prefer to slip behind my Momo steerign wheel and crank up my RB25DET. its in a different league and was built for a different purpose to appeal to a different set of ppl.

The rear suspension parts are basically the same between all 32's, 33's, s13 etc and once you start modifying things (shocks springs etc) the handling characteristics change. The skylines have better front sus set up with double wishbone setup which is supposed to be better than the setup in the silvias.

The brakes on the lines are a step above the s13's and these are all things the need to be considered.

When they were made the s13 were a cheap preformance car made for as little as possibe (look at the interior) while the skyline was a more expensive luxury performance car. Both have similar performance possibilities but the s13 would need more spent on it to match a skyline in all areas.

Don't underestimate the SR20DET. Obviously this engine is not suited to lugging a heavy ass car around inark, hence it was not produced in a GTR or similar flagship model. It is like having a 6 cylinder flagship model for Holden, dosent make sense. However you could bring in the GTiR.. which in many cases can give a GTR a run for their money :D

A S13 or similar has not got as much to offer as the Skyline, but in my opinion is a better performance orientated machine.

SLY 33 : $$?? no i don't think so man,  $$ does not make a car go faster, If you know how to drive, then that can make a  car go faster.

In my 200sx i have been a R32 gtst with the same mods, i wasn't boosted, it was just exhaust and filter, i chopped him by yonks,  

Money ain't a thing,  

Or and btw SLY 33, dunno wat you drive but if its anything but a gtst that only rev til 7......don't rev too hard, or your engine mite end up like the silvias :0

Dude, Im speaking on the basis that the cars are being driven properly. But i know what your saying. There are a few tools out there that dont have a clue how to get going quik, and even change gears quick -and cant even drive with the pedal pushed ALL the way to the floor :D

BUT $ does not make a car go faster, and Money aint a thing??!?! cmon man, that statement is a joke! Obviously you need to know how to drive. And money certainly IS a "thing" when it comes to going quicker.

And when you went that 32, are you sure he was tryin? :D nah only joking, i know that with only those basic mods, the 200's are faster. Like that s13 that did me before he blew up. (not having a go btw!)

I'm putting this question out here cause I really don't know the answer.

Say if both motors were give the same sort of mods to make.....say 250~270kw at the fly wheel. Which one would be more reilable?

The larger capacity RB25DET or the smaller SR20DET ???

I know it's a very general question, but any ideas??

A mate has a GT4 and it is/was very very fast. Fast to the point of not bothering about draging cars cause it was a waste of time. He used to drag off bikes etc !!!!

But on the same hand, this same person has blown 2 motors already.

So I'm thinking that most motors can be pushed to amazing output powers, but not many can be reliable at those powers.

Now before anyone flames me, I know the SR20DET is a better motor than the 3SGTE. But I'm just using it as an example.

I'll be the first not to go on about SR vs. RB.

Skyline gets votes for handling. Double wishbone vs Strut, take your pick. I'd go wishbone.

Chassis. Not keen on R33 as it's not hardcore (personal preference), but the 180 doesn't feel that firm. Lines are have a more communicative chassis.

Brakes, 4 pot and 2 pot for lines, 2 and single for 180. I love my brakes, and bigger/more is always better.

I personally like skylines over 180's and silvia's.

Obviously, considering I own one. But I will say that the sr20 is a Fu.ckin Good engine. A few mods and the things run awsome.

But Skylines look better, sound better, the interior is nicer and chicks love 'em.

The 180sx shape has been in production from 89-99. That’s ten years without a major facelift. It’s testament to the 180’s classic good looks and performance pedigree. Not many other Japanese cars have such a long production run (300zx & Supra).

Compared to Skylines the 32, 33 and most probably the 34, will only be in production for less than half the time. Why does Nissan have to keep changing the Skyline line up? The 180sx was and still is a great package that has not needed to be changed.

If your comparing the rb25 to the sr20 the fact that you see so many heavily worked sr20s in Japan reaffirms that it’s a better engine. However, if exhaust note is what your after then yeah rb’s rock. Japanese tuners don’t touch the rb25 cause it’s an inferior engine, and also because they can use the rb26. There is no doubt that a GTR engine is better than the sr20 for power but not everyone can be rich enough to own one!

Skylines and 180s both great cars but id take a stock 180 over a stock skyline !

They didnt give it a face lift because they didnt want to waste money and time on it when they could be designing better skylines.

Nah, just joking. I like 180's, but im guessing there focus on the sr20 was the s14's and now s15's.

S13/S14/S15 SR20DET stock

R32(RB20DET)/R33/R34 RB25DET stock

which car is quicker in a straight line? which car is quicker around a certain track?

jtir: off the top of my head (can't find my HPI so can't quote the times from them) the quickest of those in stock form was the r34gtt

then... r33

s13

r32

s14

s15

all taken for manual

however if the s15 is the jap spec, then he'll be at the top of the list...by a long shot I think...

anyway I could be wrong, but that's what I can remember and noone else is trying to answer the qeustion, so if anyone has the perf data for these cars chuck them up and that'll sort out the debate :)

Given my time again id fo the SR.

Simple maths really. 4 cyl SR vs 6cyl RB. Come rebuild time 4 pistons/rods/rings vs 6 = cheaper.

That said i luv me ol R32, one day she will get the rebuild she deserves.

And my mates 200sx (S14) is quicker than my R32 GTST, with less mods. I think if my computer was mapped for fuel & mods though it would make a huge difference.

Comparing just rb25's and sr20's

I'll bet that you cant find more examples of heavily worked rb25's

Thats not what you said. Originally, you implied that Japanese tuners don't bother working RB25's because its an inferior engine, which is bollocks. From what I can tell, Jap tuners will work just about anything that goes round and round.

If you want to base engine quality soley on the number of worked examples of that engine, that would make the 350 chev a much better engine than either the RB25 or the SR20. Is it?

DON91E, the 98+ RB25 made 206kW, compare late model SR20s with that if you really must. But really, its pointless comparing stock outputs of differently sized engines.

you are ~~~ goiong to be shock but I seriously considerd putting an sr into my r32.

but the rb20 is a good motor my r32 with an r33 turbo has run14 flat I could with development run 13.5 with out changing to much

Ie same turbo injectors etc.

the skylines need some suspension work for thier take ooffs to improve mine has this and nwo lauches liek a rocket.

s13's 180 dont have the build quality of the the r32's and have a larger interior I know cause I had to make the choice when buying my car.

they are apples and oranges

but why not think about a cefiro

    • I am getting the same issue. Did you resolve it? I just got it after installing my new super coppermix and literally the same issue, new fork, new 18mm carrier, release bearing that came with the kit and replicated the exact same sound. 
    • If you like - I have the STL files so I can email em. There's a couple of gotchas (i.e the holes are not threaded so you might need/will need) to utilize some M3 melt-in threads for some of the points. However if you want to be super accurate, and are willing to remove your calipers and your SHOCKS it's a really good tool. You also might need to scale the part that measures the tyre width a bit wider. It defaults to a 7.5in tyre and I mean who is running that. Luckily with the magic of CAD this is very easy to rescale.
    • jeebus. glad you weren't under it while performing the stunt. Also thanks for the link to the wheel measurer, exactly what I needed
    • In the older stuff there were very significant differences 2wd to 4wd, for example Stagea had strut front end for 2wd and double wishbone for 4wd so it was not minor to swap. From poking around the 2wd v37, it *looks* like it might be more possible; some of the parts specifically have "2wd" stamped on them which suggests the platforms are more similar. You'd still want to start with a 4wd half cut to swap stuff from though. I'd suggest if you don't have a tune on the ECU you don't really need one on the trans either. Throttle mapping is in the ECU side (and you can always use a Roar Pedal if you want the throttle to actually respond to your foot), and really if you are happy with the stock power you probably accept the stock trans behaviour too....its all made to be "sporty" not racey.
    • So, updates. I have not washed the car since it came back from Tassie. I've driven it around a bit but not got around to actually sorting it out. I DID raise it because I cracked the rear bar leaving a hotel which was very distressing. Interestingly, the car drives more compliant now that it's raised a fair bit (5mm front, 15mm rear). Also noticed that my FR height was 10mm lower than FL. So that's now sorted out, too. I also bought this and had it printed: https://www.etsy.com/au/listing/1576422240/wheel-and-tire-fitment-tool-universal?ref=shop_home_feat_1&dd=1&logging_key=08f604d9fa4cc383550ba985e6ac85cd5cac7fbb%3A1576422240 Now, if I was smart I would have taken my brake calipers off to actually use this correctly but it was evident enough to me that in the region where the caliper was... there was nothing to hit suspension/guard/arm wise. So I'm going with "it'll be fine" after using the tool to hopefully very precisely measure the wheel clearance. Also while doing this, I had the very VERY bad idea of jacking one of the wheels/suspension arms up while the rest of the car was on jack stands. I did this to see how the arm would travel. This all was well and good until the car slid off the stands and went through a fence. So don't do that. Incredibly nobody was hurt and there was only minor damage to the rear bumper as the car didn't have far to slide, and had 3-4 wheels on it. The only damage turned out to be the fence itself which was easy to fix, and a little bit of damage to the fibreglass rear bumper trim. I had already planned to try a touch up paint kit to fix the time I drove into my garage door to see if it'd help in the interim before I get it fixed properly. I used the Dr Colorchip kit after looking online and seeing everyone talking about it. Yes it's made for chips and not huge broken missing pieces and I'll be 500% recommending it for stone chips after using it for stupid things like me. This took about ... 10 minutes and looking at the half assed photo the 30 second job I did on the bumper corner was almost perfect just by using the tiny little brush and painting it in. The sealact stuff to remove over-painting is really useful, so if/when I do it again I'll likely slather the touch up paint well over it and then clean it up with the cleaning solution. The wheels should arrive in a couple of weeks. I am still kinda confident after doing a stupid amount of measuring (and borrowing a set of 18x10.5+15) that they will not fit because I overlooked something, somehow and flew too close to the sun. ALSO R34 GTR guard liners do not fit on a GTT. I bought the undertray brake duct guides and had the wonderful problem of them not fitting my intake, my oil cooler and the liners themselves were even worse. Attempting to fit them won't work in general - You would have to cut them up as another poster mentioned as the bodywork is different on the GTT. At least I can try to resell them. So instead of cutting those up, I cut up my old already-cut-up GTT liners and extended them by using some PP plastic and drilling some 8mm holes for some nissan clips for the 'extra' bit. Because I was happy to cut them I was able to mount them pretty damn forward so I now have some semblance of guard liners, and the brake vents seal the bumper from the bottom. It sort-of-looks like this, to give some idea - If you look at the GTR and then the GTT this is when I realised that I needed to seriously measure as the inside of the rim area is entirely, entirely, entirely different and could not take any internet measurements for granted.
