Hey anybody have a True 2 turbo setup on their FD. I was looking in the magazines and saw one. It looked very unique. I was curiuos of what kind of power the setup can produce and how much trouble it is to do the conversion. let me know of some feedbacks for those who have this kind of conversion.

Well FD's come stock with twin turbos operated in a sequential manner via a crazy mad mess of solenoids and vaccum hoses. Now if you mean non-sequential (both turbos operating at the same time) then yeah lots of people have done that. It sure makes everything a hell of a lot easier to work on and less stuff to go wrong plus there is apparently a little top end power gain as well.

No i'm talking about a True Twin setup like the ones Supra, VR4s, and 300zx uses. 2 individual turbos. Not a non-seq. setup.

Tobal...please go to your garage ..pop the hood...take a look..there are two indiv. turbos down there...

You mean twin parallel turbos - see this thread, Marcus' red 'street' (term used very loosely hehe) car.

I think he means twin after market turbos as sold by FEED and other jap companies. They are laid out on top of one another with a stainless manifold in the single turbo location of the engine bay.

Yes ... that's what he's talking about ... and as in the picture posted above this. I've seen 3 individual ones, too ... usually it's on 20Bs (900 hp range), but I've seen two 13B-REWs with three. Doesn't make much since with 3, though ... that's a complex manifold.

You mean like this one?

Yes ... that looks like the AXIA Sports 20B FD. I like that car ... clean and pretty simple.

Tobal

Yea thats the Setup i'm looking for. I guess the right terminology would be a Parallel twin setup. I heard that companies like Feed makes these setup. What kind of potential should i be looking at w/ a setup like this. Any experiences?

It's really limited to what a 13B-REW can handle boostwise and stresswise. 700 is about the upper limit of the 1.3 litre ... there's just only so much you can do with that tiny displacement.

Tobal

But with this kind of setup, is 500hp easily attained? Also what kind of lag would be expected. Looking for a good solution to high hp w/o much sacrifice of low/mid end. And with this type of setup i think it might be able to fulfill my needs. Don't want to be that greedy hehe.

just get the apex rx-6 single...form what ive heard its at as lagy as non-sequental twins(if not better) and can make 450 rwhp


the only prices ive seen were on the hks "twins"
and were arround 8-9k
the rx-6 is abt 3k..

EunosFD

Man I still can't get over how clean that 20b-3 turbo engine bay is. It's hard to believe they were able to get that much free space with all of that stuff under that hood. Granted it's not nearly as empty as the 13b above it, but still schweeet

radkins

Why woul you put a stock AST on a 20b, or it that my imagination.

Donovan

What would be the point of putting two turbos on a motor that is inline like the rotory or Supra. On a car like the Z (V6) or horizontally opposed (911)where you have 2 cylinder banks and one turbo for each side. before I get flamed I mean a non seq setup that is not just stock turbos set to run non seq. I get the point on sequental turbos. (If not Mazda's rat nest version)

I guess you should call up Nissan and ask them why they put them on the RB26DETT!

maxpesce

Because two small turbos will spool up quicker and have better part throttle response than a large single but the single will flow better at wot.Porsche offered both single and twin turbo versions of there race motors for just that reason - the twin turbo motors were better for low to mid speed tracks that put a premium on response and the single turbos were better for high speed tracks where the throttle is used basically like an ON/OFF Switch! and the the car spends lots of time at wot.

TOBAL lol here.... http://www.mkiv.com/techarticles/ettc/index.html

Ok, guys what tobal means is... Turbos stock run sequentially. 1 and then the 2nd after the pressure tank builds up. Running True Twin Turbo (TTC), allows you to have both turbos spooling at the same time even at idle. It elminates the kickstart the 2nd turbo gets during the transition from 1st to 2nd in stock sequential mode. TOBAL the link i gave you is set up to show you how to connect TTC up to a switch. Dont pay attention to the pictures cause its set up for a supra. Just read how to do it and which wires you connect the swtich to. Also find out which wires from the IACV and the EGRV lead to on the ECU. You cant get 500 HP just from runinng TTC but it does give you a bit more boost and a much stronger powerband. So happy boosting TOBAL, hope this helped.

No turbo setup spools at idle, and thank the maker for that.....
