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:

    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
