Anyone know anything about RX7's - GT-R Register - Official Nissan Skyline and GTR Owners Club forum

Jags · 24th June 2009, 11:59 AM

As above, does anyone know much about RX7's? The FD3S last shape one. Are they really that bad on fuel consumption and oil useage? As I understand it they need rebuilds quite often and suffer from overheating quite badly.

Also has anyone done an engine conversion- say an SR2O? How easy/striaghtforward would something like this be? (or not as the case may be!)

Couple of RX owners on the board!

Miguel for starters has a lovely example.

Oh and REXtreme.. (http://rextremeii.blogspot.com/)

Basicly if you look at FD RX7s you look at a car that has been build for 10 years streight. A 2001 Spirit-R is probably the optiumum when you talk standard RX7s. It is refined engine wise, has better breaks, better interior, ex . . . . where first gen RX7s from 92 will largely suffer from the age. (Compression, Turbo, oil, cooling . . .).

Fuel is hell with RX7s and if you want to care them professionaly they will also empty your pockets with oil servicing, if driven on a daily basis.

Miguel can give the best quotes on them , as he is a long time owner.

^^That's what I was a bit woried about with regards to the engines- dont seem to be too great as a daily driver like the GTR is. What about engine conversions, anybody got any info on this? Ideally like an sr20 out of the s14 or something similar.

mifn21 · 24th June 2009, 05:04 PM

Don't ruin the car by putting in an sr20! 13B rebuilds aren't that expensive, budget for one when looking for a car.

If you go single turbo your mpg goes up quite a bit, the twin turbos (especially in sequential mode) spool up very quickly which hurts fuel economy, the single will come in later so if you're pottering about they aren't as bad on petrol

I want

Flamage is good, although too much flamage can has have some slightly unwanted effects.....

After doing some further research it appears that the 2jz or 1jz is a popular conversion over in the states using the tech2 kit. I think it would probably work out too costly to do this over here though.

If you love her, you can forgive her. It's all relative. I could have forgiven mine for almost anything, and I loved every little curve to her. The driving is something special with that low end torque, and the sound of the fibrillating rotary engine. ooohhh... why would anyone want to swap that out? Cabin quality is not great, and it's a pretty tight squeeze getting in and out, and there's not a lot of room for the shopping...

The only thing that I would say is try to find one that has known history and has been well looked after.

Hugo · 25th June 2009, 07:49 AM

Swapping the rotary is a sin!

You can do two rotary rebuilds for the price of one RB rebuild.

YokoAE86 · 25th June 2009, 08:58 AM

The FD3S 13B rotary engine is a great engine. The problem is that people do not know how to look after them properly, thus requiring engine rebuilt at a cost of £2-3K. The cars are now over 15 years old. Don't be fooled into buying low priced examples. I have seen too much of this. Rebuilds are usually required at 70-80K miles.

Firstly, the best you can do is buy a low mileage example that has been cared for. FSH and recent oil changes. Also the rex is known to flood the engine. Make sure that you warm the car up and down everytime. That way, you can start the at the click off a turn.

Start off with the twins and then go single if you need to. No need to change to another engine. You should get 20mpg.

matty32 · 25th June 2009, 09:18 AM

No go for a daily driver

Lovely cars if kitted up :-)

Fuel bills will kill you & factor in a rebuild on whatever one you get

That's the site I've been looking at ans also the tech 2 site.

Such a pretty car but I think it's going to be an absoloute killer for a daily drive (something that I need). The RX7 idea may have to go out of the window

Thrust · 25th June 2009, 01:50 PM

Sounds like you are shying away, and you may have gone for common sense, but an RX7 is a car that everyone should have the chance to try at least once in this lifetime. How could you sample all the various ethnic foods and avoid Thai for example?

Miguel - Newera · 25th June 2009, 03:38 PM

If you do a search, you'll find some long discussion I've posted before on RX-7's.

13B is not any more or less unreliable than an RB26. Much fewer moving parts in the engine too. Only people who have never owned a pukka one, or bought a cheap tired example tend to say they're unreliable...

Although I had an R33 GT-R V-Spec daily driver from about 2000 - 2003, I sold it a few months after the RX-7 came along. I just preferred the nimble handling and the rotary engine and the GT-R became sadly neglected as I always drove the RX-7...
I've still got a rotor shaped smile on my face

Still love it to bits and embarking on the 8th year of ownership now...I've no intention of ever selling my rex.
