hi guys - just after your thoughts on which model will suit better.

it will be a daily driver with the occasional track day or autocross.

my current car is an xr6t - so am concerned the rb20 will lack some power (but will be better on fuel)

the 33 is obviously a tad newer and more powerful but will cost more to run as a daily drive.

on a side note - do the rb's suffer any oil starvation issues under cornering? or should they be fine on the occasional track day?

Depends on how old you like your cars...Do not underestimate an R32 GTST compared to your XR6....as gutless as R32s are off boost...when the revs are there they are certainly capable of giving the XR6 a fright.I know my old one did.Fuel economy is nothing special...it runs lower comp than a R33...As much as I Love R32s I would recommend the R33...fresher car for close to the same money, lots more low end torque also

so similar in performance because of the extra weight in the 33?

i dont underestimate the power of the 32 - i've just become accustomed to having the 450nm from 2k rpm in the xr6t. lazy power.

im just a tad under 6 foot - will a 32 with sunroof have enough room for a helmet?

u can under estimate the r32 gtst, unless it has mods such as turbo, cooler, exhaust..

most ppl just do a cooler and exhaust mod, and they are so bloody slow its not funny. i was going to buy one @ one stage when i had my rx7, and i made the mistake of driving my rx7 to the road test.. it was a fairly stock gtst with cooler and exhaust mods only runnin 10psi...

it was the most disappointing drive of my life. Driving an Integra Type R was more exciting then again, they are faster stock for stock.

until u do mods like turbos and so forth, they arent even worth a mention.

The R33 on the other hand, has enough torque (read 340nm+.. dont know exact figure but im sure its more than 340nm) and power from factory to give ur xr6t a good run for its money.. factor in exhaust and cooler upgrades and some boost and they can be pretty darn fast..

Ive never liked the R33 gtst.. ever but i gotta say that they are a far superior car to the r32 gtst in every single way

i would pick a RB25 over a RB20 any day of the week

the RB20 does very pretty hard but wat ive noticed to be its biggest let down is when u start modifying for more power is the RB20 doesnt spool up turbo's very well

ive driven RB20's with GT30's and they have big lag where as if u bolt a GT35 to a Rb25 it isnt no where near as laggy

The 2.0 litre inline 6 motor dates back to the Hakosuka GTR (1969-1972) with a N/A 2.0 litre inline 6,

which produced an awesome sound from the exhaust and won 58 races.

I've searched and found this link to what the Hakosuka GTR sounds like and the race history of

this amazing car -

RB20 in the GTS-R (1987-1989) continued this awesome sound and is why most buy the GTS-R and

lightly mod it.

Here's what the GTS-R sounds like -

R32 GTS-T (1989-1993) inherited the victory spec version of RB20DET from the GTS-R. The R32 GTS-T had bigger

brakes than GTS-R and better chassis, suspension setup but engine was detuned for road use.

For sound = RB20

For power = RB25, RB26, RB30

Since you like torque and are used to it, I would say R33 or R34 GTT with RB30 (3.0 litre bottomend).

If Rb20 are so bad why is all the R33 and R34 rwd track cars are slower then my GTSt with a turbo upograde on an internally std engine. Is the RB25 a better motor? Hell yes. By the margin ppl make out? NO WAY.

You have to look at the whole picture to understand why an RB20 powered R32 can easily punch with an R33 RB25. First you have the weight, only small advantage, but its basically an extra passenger so is measurable.

But the main reason is the old two stroke style gearing. When R33 owners are grabbing 4th gear at abour 170km.h the R32 driver is grabbing 5th gear. The R32 has much shorter gearing, so everyone that is obsessed about response...well who cares, for a given road speed you have more revs on board so you are making boost and power. So dont get obsessed with rpm where it makes boost, thats why we have manual gearboxes and diff ratios, worry abou tthe road speed where it makes boost. And on that front....have a look at the comparison of

- My internally std RB20 running PFc and TD06-20G

- An R34 GTT with Poncams and GCG Hi FLow and PFc (same tuner and dyno as me)

- Another R34 GTT with Hi-Flow and i think this dyno sheet is on a fully built motor with cams. But lets just say its an internally std Neo sa the sheet could be an old one for the car.

Either way, once you stop worrying about revs where you make power and consider road speed. Then the R32s slightly less weight and shorter gearing ensures you can still do the job.

R33 for sure... RB20 engines are piss weak (if stock for stock) and they look hideous (excluding the GTR).

riiight....u think r33's look good??? haha yeh chek this beauty out...

pffffft....

wat u want is one of these... :)

minor mods on an 32gtst get it moving fairly swiftly

r32 punches an r33? lol ive never read something so silly in my life.

stock for stock r32 is the slowest rubbish box in the world from factory theyre what? 7 secs 0-100?

theyre 15yo+ cars and they wish they could pull those numbers

the r33 is faster and its been proven millions of times.

do the exact same mods to each car and the r32 just gets left further behind

Didn't take you long did it Roy? Ha ha :)

I have to say owning the R32 gtst was a good experience. The beauty of the Rb20 is the low cost replacement meaning you can lean on them with little fear of financial backlash :laugh:

I think if your going to stay at or below 240rwkw the RB20 with the right turbo doesn't make a bad unit for a budget compromise, on standard internals.

ROFL

u didnt choose the right color man, shooda been burgundy, lol

but seriously, the 33 s2 in black looks teh goodz

no1 should underestimate the 32 though, its physically smaller, lighter, and as above mentioned, shorter ratios

which means huge advantages on track

now to add a few huge generalisations to go with the flow

1. get a 32 for track

2. get a 33 for str8 line spammmmmmmmmmmmmmmmm

:)

Well there are some drawbacks with the stocker R32's despite the gearbox ratios the gearboxes are weak. Despite the weight saving the chassis stiffness needs a little more help and they are less aerodynamic. The brakes are also not as good.

Depending on what you do tho' those things may not actually matter.

Ok then, if Aurace is in Vic, you are welcome to a drive of my car to help you form your own opinion. Best get some personal experience...its your dime, go with what you find to be right. If you find the right R32 GTSt you shoudl not dismiss it because it has an RB20. That said, find a nice R33 then you should grab it provided the premium $$$ over the R32 can justify it.

Bumblebee...care to come to Phillip Island on Anzac weekend and see if i can change your mind about RB20s :) If i spank your GTR then you have to wash my car in a bikini at the next club meeting....and vice versa :)t

Hey, they are weaker then other boxes. But they are by no means weak as in they break when you start the car. They are reasonably durable provided yo udrive with some care. Mine has +190,000kms on it, its on its 3rd clutch...god knows how many track days i have done in this car (possibly +75 in total, 8 years of track work, 3 years of motorkhanas, a few hill climbs, some runs at the drags where it has done a 12.9 @114mph, two Dutton Rallys)

You just need to respect the fact that they will break if abused....secret to getting a long life out of the box is good Castrol Syntrax 75W/90 . Cant beat it. But yes, unlike most other Skylines which are all but bullet proof in teh drivetrain, the RB20 box is the weakest of the breed. :wub:

Re oil starvation, i just give it an extra 500ml of oil so that when you are up it and some oil gets caught in the head, you still have plenty of oil in the sump. I have run an internally std engine since buying the car. I did spin a bottom end bearign on an engine, but that was only because whilst the car was at the mechanics the car was jacked from the sump and there was a massive dent put in the sump right where the pick up was...that and when they tuned it they didnt put Castrol Edge 10W60 but some Penszoil shit...so the recipe was there for trouble, cheap oil and damage to the sump. Was not happy with the service i got at that mechanics :D

As for daily driver going to the track,

Car 36 -18th And that was with me udner the weather lapping 2 seconds of what i can comfortably do.

Car 36-15th

Thats in a GTSt with a turbo upgrade and basic suspension mods.

LOL, not saying RB20s are the best, they are actually the worst of the twin cams RBs for making power. But they can still get great, reliable results to the point that their use need not be a handicap. But a benefit in that you get to spend the money in areas that actually make the car far quicker.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
