FD has better balance, infinitely better handling and stock for stock more reliable than shitty RB's

Finding an unmolested example of either is very difficult these days

FD's consistently hosed GTR's in the 12hr races in early 90's. That should give you a clue.

Rb over a rotor any day.

More grip

350kw on stock motor

Don't have to put 2 stroke in it to stop it burning oil

Better fuel consumption

350kw? are you high? more like 270 MAX. Struggle to hit that on a stock R.

I would argue that stock for stock GTR's are much more reliable TBH. Rotors are more touchy than a woman on her period.

Basically with a rotor be ready to rebuild it. They have massive overheating issues that you need to address properly. They have the smallest heat margin i have ever seen. It's something like 10 degrees is the difference between all is well and bang. They can be trouble when trying to push too much power out of them.

In saying that GTR's have issues as well. It all depends under what application you are driving. The oil control comes into play if you want to move them in any way.

So it depends. Do you want to spend thousands fixing cooling issues in the RX7 or thousands fixing oil issues in the GTR.

Both cars will require another $5000 around that ontop of what you spend to buy it at least to make them reliable. This is not taking into account performance upgrades at all, this is the money i would spend to make them daily reliable. Provided the engines are in good condition to start with.

Also FD's are f**king tiny. No space what so ever, many people i know struggle to even fit in them. Trying to get the interior to look nice with the required gauges you need is almost impossible.

FD's do handle really nicely in stock form. You could get one and not have to touch the suspension. GTR's are not tooooo bad. In stock form they will understeer, sway bars will counter this issue.

One of my very good friends has 2001 FD3s RS currently on the boat coming here. It's going straight to Ric Shaw to get intercooler, radiator, and gauges done. He isn't even confident to drive it back to canberra without the radiator and intercooler done. They are that bad.

TL;DR they are both money pits. Don't buy 1 unless you can afford 2.

Apart from that it will be personal opinion. What one do you prefer? Do you want the braap braap of a rotor or the howl of an RB?

just my 2c.

You talking rotors in general, or FD's in particular? When I had cooling issues, then fan-belt alignment issues I saw my 12A spike over 120 deg lots of times, and it spent a lot of time over 110 deg. Never went Bang, nor did it need a rebuild. Must admit it was getting a bit tired by the time I sold it - I'd spent 5 years rallying it, and god knows how long since it had a rebuild before I bought it (I'd sorted the cooling issues by then, and it ran a comfortable 90 deg no matter what I did to it)

Well maintained rotors are as reliable as anything else on the road. I'm hearing a lot more reliability issues from RB's than I do about injected rotors. Of course bolting a huge turbo and running 800HP out of a rotor is going to make it wear out faster.

Very true comment about personal preference. The RX7 was built from ground up as a sports car. The Skyline is a converted family car (although build quality is admittedly very good - no doubt about that). Different cars for different markets. Personally I'd go a stock FD over a stock GTR but I've always preferred nimble cars to brute strength. I think for dollars spent on mods, an FD would be faster and more reliable.

Just realised who OP is.

Nothing more than another theoretical discussion point, then.

Ask this same question at OzRotor and see what responses you get

Rotang FTW.

Just as long as you like noise and buying petrol and rebuilding motors.

Depends if you like Rb's or Rotors

Also depends what car you like the look of

I will own a RX3 Savana one day.

Been trying to convince my uncle to sell me his, Been sitting in the gararge for the last 15 years with a 20b or 26b from memory

they also lied about their engine capacity to win races.

they don't go that we'll for the 3.9l engine they are.

Personally, as a stock daily, you don't need to touch the oil system on a gtr.

short blasts are fine, and that's all you'd be doing on the road.

never had a problem with mine.

Not sure about the rx7 as I've never driven one, but would like to one day.

      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.
