should i get a single or twin turbo?

[AtomicRex]

Yes. ALL RX-7\'s were twin turbo from the factory. Any single turbo rex is aftermarket.
 
I\'m led to believe singles are slightly better on mpg. I could be wrong. Hopefully someone with more rotary experience can correct me if i\'m wrong.

I get less than 4mpg out of ours.....so Id hate to think what it would have done on twins!

if you mod your car to 400bhp and mine is stock. yours will blow up before mine:WaveBye

Most likely a car making 400bhp with equal servicing and driving to a stocker will see higher wear and tear, but that wasn\'t what you said.

You said more mods = less reliable, thats cr4p.

If you take a stock motor, add a bigger rad, a better intercooler and a decent map, it should be much more reliable.

Remove the complicated / problematic twins and replace with a properly set up small / medium single at stock-ish boost and you have the optimum setup for reliability, with extra power and lower temps to boot.

Get a single if you can find one with the right mods done. just make sure the turbo DOES NOT have XS power wirtten on it.

Agreed, I\'ve had both and I believe my single is more reliable - lower inlet temps, less likely parts will fail (as 16year old parts replaced with uprated newer ones), premix instead of relying on omp, etc etc. Drive both before deciding, the twin turbo kick is a novelty at first but I prefer single:Thumbsup!

i get a about 230 240 miles out of a full tank of vpower at 112 a litre if your down this way mate happy to meet up and have a chat im on a single gt35r at the mo with a v mount

[strange_days_uk]

single is the best, if properly setup

My twin turbo is for sale if your interested.  Running just over 300bhp at the flywheel and fully tuned by WGT.
Plus I\'m only in Newport :-)

Twins are the best for a smooth drive and good low down torque and they have instant acceleration.

With some single turbos your waiting for them to spool up and if you wanted to accelerate at a half decent pace while your pootling about in a single turbo rex you would have to knock it down a gear. I would probably find that a bit annoying. Although you wouldnt have a big problem with this if it had a smaller size turbo.

However if you wanted a seriously fun RX7 id say that uprated twins are the best such as the knightsports or the BNR\'s. ive driven one on uprated twins and it was good stuff.

I never seen any boost issues with mine, and as i use mine as a weekend toy it never gets boring for me to warrant spending a grand or two on a single conversion. Even as stock the Rx7 is a really fast car.

You best off taking both types out for a drive, and reading up in the FAQ section on this here site.

And drive a non-sequential too

hey how much u want for it? how many miles it done? have it had a rebuild?

[jamie_supra]

test drive both and decide what feels better for you. ih had both and i personally think that the singles are more fun. also i have found it more fuel efficient ( if you drive carefully) - as the turbo doesnt kick in until 4500 .  im not sure how having a single effects reliability though........... i am on my 3rd engine in a year!!!!

[AshRX]

Owned both now.

Even on a T51 i get better mpg and on mine its a lot smoother boost over 3k and a lot nicer to drive

Stocks are good for instant power but only power up to 7k ish as per a single on mine where i can take the boost till 8200.

In my experience of owning both the single turbo causes me less hassle than twins as if something does go wrong its easier to work out to get to the bottom of the problem.

I agree with the others though better supporting mods and a good map will see an engine of any spec last just as long as twins
