Was 6 Turbo's Topic Now Twin Turbo Ideas


Recommended Posts

I read up in a mag that some guy in the US "I think" Has made a 4 cil per piston turbo engine.

Just wondering if I did a rebuild and made the 20 a 24 put 6 T25's or maybe the 28 how would it go.

Also what would I need to do

I know I would need a aftermarket CPU or chip the 32 one

Bigger injectors and Fuel pump

what do you guys think?

This is a what if BTW.

You are kidding right.....

you want to put 6 turbos on an RB20? where exactly? 3 in the boot and 3 in the passanger seat?

Even If you managed via some technical mastery to fit 6 turbos on the side of an rb20 it would not spool untill 9000+ rpm....

Perhaps you should buy yourself a bag of HKS sand and give the head a port and polish first...

Here is a really good guide on doing it

the rb20 has enough trouble pushing 1 of it's own turbos let alone 6.

Anything bigger than a 2510/2530 and the rb20 sucks starts becoming quite low in response. Especially in the low rpm range.

people have done 2 stock rb20 turbos on an rb20 and it was laggy as hell. 6 - you have to be dreaming.

an rb20 is already to laggy with the stock turbo!, No stroke combined with no compression, combined with no displacement doesnt make for the most driveable combo, and you want to add 6 turbos?, you smoke rock?

like i said just a play around also the stock turbo isnt that bad mine was full boost at 2500 rpm the one i have on now is 3500 so not as bad as some

k, that 1 turbo spools full boost at 2500 (watever that boost is) off 6 cylinders lol. 6 Turbo's at 1 cyl a piece would mean that each turbo should come on boost at about 15,000RPM lol

well whats I was thinking was 6 T05's you know the small exar turbo's off the 1.6 they are very small hey and cheap so if they blow who cares

Edit: I downloaded that guys Engine run Sounds sooooo sweet even for a V8

given its a what if ill throw in my what if solution..

forget 6 t25's or the like, ideally what you'd be better of looking at is something like the turbos found on either starlets, or more preferably, the 600cc k cars out of japan, something really small...

a few reasons for this

size, the physical turbo's themsleves are not big, and ideally, with smart plumbing, you could possibly pull it off, without having to chop apart the firewall/strut towers to get them all in, probably involve some careateive manifold runners and a careful think through

response, given the 600cc jobs are driven by very little, ideally, with 2.4l of capacity, you'd still end up with a car that actually had boost below 6k

tuning it would be mighty interesting but itd be fairly exciting to pull off.. if i had wads of cash laying around and was bored id go do it for a giggle myself

I don't think there are turbos small enough to make it doable. You will be feeding each turbo with ~330-400cc cylinders, each of which are not good turbo spool cylinders. 6 T25s would be ridiculously laggy. No way near worth the effort or expense.

Here is a pic of an EVO 4G63 with 4 turbos though, to give a rough idea of what a "clean" turbo per cylinder setup looks like:

    • It depends on what the guy who bought its Ratio is. Mine is a 4.36 Jus Jap told me anything above a 3:9 has equal length shafts which the Nismo center's shafts were not.
    • If those shafts in the last 2 photos are the ones that came with the diff, you have no hope of fitting the other ones because they are completely different 
    • I have recently fitted a Nismo GT Pro Center second Hand buy still in the box i got stubs with it but they are 5 bolt and I need 6 (3x2) I was told by Just Jap that for a 4:36 ratio the stub axles are equal length sku 38220-0V161. They didn't have any in stock but I picked up the ones pictured. The one with 5 bolt are the ones that came with the LSD. The right side went in no issues but the right....I have happened the fk out of it put it in a press and it still sticks out about 5mm too far. It was sticking out about 25mm but after bashing it like Chris Brown did to Rhianna I managed to get it a bit further in but seems stuck again now. Any ideas? Should I just leave it 5mm out and send it?        
    • Meh. I "see" a typo above, that should have been "sell".
    • The clutch pedal has a procedure for adjustment. This can only be done after you are 100% sure the system is absolutely free of air bubbles. You must bleed the clutch master cylinder first, then the "separation pipe" which is the clutch damper line, then the operating cylinder as detailed in the service manual. Also, you must fully depress the clutch pedal between shifts. Just because you can't feel it grabbing does not mean the input shaft is truly decoupled from the crank. At high RPM clutch plates are vibrating and moving around, you need to give it the best possible chance of success. On the BCNR33 Nissan revises these adjustment procedures slightly but not by much: I would be careful with trying to play games with these adjustments. As for the Nismo operating cylinder they say a lot of things. In practice the twin plate clutch needs less movement on the clutch fork to disengage because the whole stackup of the flywheel + friction plates + pressure plate is much taller. Personally if you find that the clutch still disengages too high at the top of the travel I would try the Nismo operating cylinder. Make sure to follow the air bleed procedures.
