ANY INFO ON A RB20DET with a RB26 head?

[sillyvia13]

Hey guys, wondering if any ones has any info on a rb20det engine with a rb26dett head?
I know there is ALOT of machine work needed seeing bore is almost 8mm difference.
I know that probly no one in the states has ever heard of this due to my 3 hours search on info, so hoping that somoeone here knows a bit about it? maybe some guys in japan? any info would be great...
ie...machine work needed?
crank? rb26?
etc...

My buddy just got it, today, and I am really curious how they got it done?

the intake was modded to high heavens...rb26dett intake mani weld to itb's without itb's! rb20det throlle body welded to intake!
coolant system modded to high heavens...pretty cool he included a coolant bleeder into system with a coolant sensor into pipe alos for aftermarket gauge
also has the stock bov moved to infront of mani with a recirc tube, bov is welded to the gredyy intercooler pipe!
looks "stock" other than custom welding...if you didn't have a knowledge of engines ie rb's you may think this was a stock engine, very clean engine, no major power mods. very interesting!
We have swapped 20' 25's and 26's and this engine makes a sound like no other...I have a "test chassis" I install engines in before cars, was a old front clip I did some modding to, any who we got it going 1 hour after having it in shop and again sounds GREAT, deep, powerfull sounds!!!
rb26dett engines sound very smooth and just plain beautiful~
rb20det sound real raw and bad ass...this one sounds more raw and x2 BA! lol...

umm.. that motor looks like shit.

that intake manifold is just scary.

and i dont understand what your question even is.

and i think what your friend has is a rb20det with rb26 parts(ie covers intake mani, and possibly swapped to the twin turbo setup.

lol...have you ever seen a rb26? there is clearly one turbo on this engine!
its a single turbo. from a rb20. the HEAD is 26. mani 26 welded to itb bracket...

you must get BRAND NEW ENGINES cause I often recieve engines and all in all this is CLEAN. esp for a modded engine. front main seal is not covered in oil debris, no coolant or oil leaks seeps or any trace of...lol...your work must be TOP NOTCH to make comments like that...lol...

What makes you think thats a 26 head? The 26 mani could just be welded to the 20/25 runners. Have seen many that way and even seen many 20/25 engines using the 26 valve covers. Anyway, not sure about the 20 but the head can be and has been used on the 25. you just need to seal the extra oil port in the block. the studs are smaller but the head will stay in place when torqued. teh block should say what it is and if you swap you should be able to tell what head you have if you remove the valve covers.

block says rb20.

[hashiriya13]

My 26 had a 20 plate on the block because I had it in a type m. a way to fool the JCI peeps. here is a pic of a 26 head. take note of the number on the head and the pattern of the manifold bolts. If mani bolts don't match the pic its not a 26 head.

no kidding. but damn.. it look like a dr suess creation:keke:

i have a rb20 in my car :)

i was about to laugh at those comments to but u beat me to it russ! lol.... you never heard of the twin conversion back to single turbo conversion? duh!

Age: 19..... makes sense now

obviously in the intake and stuff will look a lilttle off..... ITS BEEN CUSTOM MODDED to make this work.... cut weld.... cut braze.... etc etc.... its not gonna look oem

jon dont bring age into this, age doesnt always=ignorance.

as far as the engine looking like shit, who car? FUNCTION OVER FASHION.

okay okay your not understanding.

engine looking like shit means- those welds are scary, the coolant lines little scary.

i know motors are dirty shiet.

welds are not PRETTY but function WELL!
coolant lines to me look AWESOME! if you see what this guy had to do to make it happen! you would have a different pov...
I will make sure all is good in head area and see!

[Grenade180sx]

well. enough non sense more power to you if it truly is a rb20 with a 26 head...

but ill just steal sum 26 internals for my 20. and make it transform into a rb24 :)

edit...more power to him not me! I got nothing but jealousy (sp?)
rb20 head flow like turd from my research...25/26 head flows bettererest!

[Grenade180sx]

yeah 20 valves next to a 25 look like childs play.

but i love my 20.

[hijack3d]

My hunch is RB26 parts, not an RB26 head... But I could be wrong, just skeptical :) Cool though for your friend already getting an engine already like that... regardless if it's really a 26 head. I just hope he didn't pay too much extra for that..

About RB24...I wrote a little bit about this on another forum I used to mod when doing my 20 build (like 2yrs ago)... Very hard to do, need crank, rods, and 82mm pistons to get a displacement of approx 2335cc. I had everything sitting there, but all the time/money/Motrin that I would've had to worry about.. Let's just say it's cheaper and less of a headache to buy and turbo charge an RB25DE :)

no it was $1100 shipped with all but mafs...
NASTY DEAL. compression is good.
fired right up first try.
prepping car for it now!
this is his drift engine...a track only s13 coupe.

[projectRDM]

I agree, that's probably an RB20 head with a chopped up RB26 plenum and exhaust manifold. Pull the head and see.

[300hp owen]

mos def a chopped RB20 intake to accept the RB26 plenum.


whoopdeedoooo .
thats almost ghetto rigged.

[DC5RACER]

i dont see the nissan vvt valve on that head...does it have one? cause to my understanding most 25's do and all 26's do. and i think 25/26 vavle covers all are flat.

[Grenade180sx]

covers are interchangeable on all models.

meaning you can have rb26 cam covers on a rb20 head.

This is what it looks like to me, snip.... edit time :D after looking at RB26's again that is a 26 front cover and valve covers though, but I still don't know. A RB20 would easily take a a 26 front cover and 26 valve covers. That motor looks might odd to me.
I personally would not buy a engine like that.

listen to this dude, these studs will tell you whats up.........note their location and the numbers on the head.

[sillyvia13]

it's a 20 head and block.
oh well.
still will be fun blowing it up!

[blu808]

Fail.

I want my 3 minutes back. lol

[Felix180sx]

im actually interested how much power that engine is gonna make with that RB26 head, you should Dyno the engine once its in a car. if you got the RB26 head cant you run a twin turbo set-up?

your understanding fails.

go back to dc5's

first off, RB26's didnt have vct, unless its an aftermarket hks V-cam

and rb26 valve covers about as flat as carmen electra's chest.

[sillyvia13]

Fail.

I want my 3 minutes back. lol
lol...you should undersatnd how my buddy feels after buying an engine advertised as a rb20 with a rb26dett head...
Damn importers lieing to make a buck! all in all it will pull, and we will like it. drift car engine, the driver is REAL HEAVY footed, not a real good thing but it is sure fun to watch!

The 26 never came with VVT. The Neo engines did but none were 26's.
