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.

Why don't you go an odd 7? :thumbsup:

6 running off the engine and 1 runningoff all of the combined wastegate collections. Wouldn't be that hard and cheap too?

This guy did a car with 8. BEAT THAT MOFOZZZ!!! It has 50 hundered horsepowers.

Eidt - damn grammar.

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:

    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
    • Well they got my money but they are not getting my gearbox ! 
    • It's needed for rolling idle up, and I think it is a decider on VCT also.
    • I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it.
