guys i am building one from crank up and am planning on turbo charging it. I was wondering if there would be any advantage to twin charging it or would this be a waste. I would like some points of view on this pros and cons if you have them. My goal is to have a r50 that will hang with the best of them. Thanks in advance for your thoughts. Oh and all of the internals will be changed out to take the beating i throw there way.

 

Twins will spool quicker because you'll be using 2 smaller units and will act a lot better down low. But, with 2x the turbos will come 2x the cost. All out (and I mean all out), usually go with a big single. A single done properly will spool just as quickly, cost less, and be a lot less fabrication. On the other hand, how many twin turbo 4cyl's are there running around? IMO, go with a properly sized and scienced out single.

 

A twin would be a lot harder and more expensive to fabricate and would be completely inefficient. Go with the Single.

 

Here's your twin turbo I-4. The only one ive ever seen in person. He is having a heck of a time getting it tuned properly and really isnt producing much more HP then the rest of us single turboer's. He basically only did it to see if it could be done in a Miata

 

I've seen 1 other pic of an I4 with twins and that was a Honda done totally as a show car. It's overkill on a 4 banger, never worth the time, effort, and money that gets put into it unless you want the shock factor.

 

built this over 10yrs ago - first twin turbo B16A CRX street car. Made over 450whp, ran 11.1 ET at 127 MPH at Pomona in 1998.

 

You my wise friend have no clue what your talking about...

 

tough being a "NOOB"

 

sequential twins or true twins? how would you do twins? 1 turbo for each 2 cylinders? sequential would be a nightmare to control. sounds really ambitious

 

The setup I saw was 2 header pipes sharing a common flange and then plumbed like a typical twin turbo setup. It was 2 pipes that ran out the exhaust and 2 more that ran boost into a dual inlet intercooler and a single larger outlet.

 

Please keep in touch with me on how the turboing goes.

Im really looking at turboing my R50

lol Turbo R50 ftw...

 

R50 TURBO KIT USING R53 INTAKE AND WATER/AIR INTERCOOLER.

 

Ooo... price/availability?

Maybe when Dougal is out of warranty...

(Jerseygirl then leans over and smacks me... )

 

yay for r50 love

 

I can see a twin turbo going wrong very fast with only 4 cylinders. But then again the fireball mini is using a supercharger and a turbo charger isnt it?

And when is that turbo kit (in the red mini two posts before) going to be available? Im very interested

 

What else had to be done? Whoa. I want. Too bad the camera and scuba gear is going keep me from doing such a thing.
