[drftns14]

ok im putting an rb26dett in my s14 the ? list:

1-can i bolt up an rb20 trans to the rb262-what clutch and flywheel do i have to use for it to work3-can i use my stock s14 non abs drivesaft with the rb20 trans4-im looking into pgrading to a big twin turbo setup (t3/t4) will they fit in the engineb bay5-im looking for great powerband and great quick boost response are the twin t3/t4 good for this?

im a noob at this swap done supra sc300 jz swaps and lots and lots of sr and ka swaps but no rb's. i know u need mount kits and wiring and maybe a custom drive shaft depending on trans but is there anything eles i should be aware of?

6-what is the best hp # out of stock setup and what is need to get around the 400whp range?pleae the more info the better!thanks,paul

All r32 and most r33 rb26's suffer from the crank collar issue. That is the olney problem with rb26's as long as you do proper maintenance. Like water pump, timing belt, gasket set ect...... Think of how long the engine has probly sat. I use to have a rb20 trans on my rb26. The rb26 clutch and flywheel will work as long as its a push type clutch. Im running a os giken clutch that was originally on a rb26 on my rb20. People use rb25 trans because they are like twice as strong as long as you use the correct fluids. The rb20 trans is the same as a ka/sr trans. Ive seen too many shattered gears in drift cars from my friend's sr's. But rb20 trans are easy to fix you just swap bell housings with a ka trans. Ka trans can be found for 40-100. ALL I HAVE TO SAY IS USE THE FLASHING SEARCH BUTTON ON TOP CENTER OF YOUR SCREEN. You will learn more by just reading old posts then asking dum questions about something you know nothing about. Learn about the engine then ask questions. Just putting big turbos on the engine is going to get you no were. You have to have all the other supporting mods to make then work. The car is olney as strong as its weakest link. One could tune the car for 350 hp with stock turbos, upgraded air filters and nice exhaust. I would spend money on things to tune your engine and make it run good before one blows money on turbos. 350hp is more than enough to blow apart a rb20 trans. Spend the money making the swap work correctly not on dum parts that you don't need. Or you will be half way into your swap broke as a joke and with a crappy engine that just going to blow up and cost you more money. I hope you have 10k saved to do the swap correctly. This is not a budget ballin swap. The engine is olney as good as its tune so make sure you have money for tuning and parts once you do get the swap running. Im real sick of typing JUST SEARCH you will be best off. A post like yours comes once a week by noobs. It gets real old your lucky I even responded or anybody.

geez dude, take it easy, maybe he is new at these thing, nobody was born knowing everything, so thats why we should help out every1, cuz we are one big nissan family

I was once in his shoes it's time he gets a kick in the back side and comes to reality on stuff. Im still a noob when it comes to engine building. Im in no way saying i know everything but in just leading him down the fast road to reality in rb swaps. He will lean fastest if he doesn't get vague replies like your first one. But best thing is to just sit down and read for a good day. look at what others have done and how there engines ended up in the long run. How does he know that you or even anybody that replies to his question speaks the truth it could all be hear say ect...... THATS MY TWO CENTS

RB20s break RB20 transmissions.

i don't know if the s14 driveshaft fits an rb20, but even if it did why would you use it?? the purpose of upgrading to a one piece driveshaft with the rb26 is about strength as much as fitment - remember you are almost doubling your torque and hp. good luck.

no the purpose is because the stock shaft doesnt work in a RB25 transmission (what usually goes in with a RB26)

the stock driveshaft works fine even at high horsepower levels.

[skylinegrl13]

do people keep the stock DS when they do the ka24de-t?? do you have an idea what the DS is good to (300hp, 400hp, etc)? very interesting...

[Joe]

lots of people do, but i dont know how many for sure

strength isnt the reason most of the time people upgrade, its the fact the stock driveshaft is HEAVY, and not designed for quick power response and delivery. its designed to reduce drivetrain noise and vibration.

an aftermarket one will free up a few HP but give a decent noticeable change in throttle response. its like going to a lightened flywheel, same principal.

[themadscientist]

carrier bearings FTL. I want a 1-piece aluminum shaft. Who is everyone getting thier driveshafts through?

[skylinegrl13]

i got mine from mckinney. i think their are other places too. google.

[Carl H]

almost any competent dirveline shop can make a dirveshaft for you, offroading stores are good bets because they have to make new driveline for lifted vehicles.

[dsm]

I get them made locally for around $200, so just get the phone book and start calling transmission shops.

[themadscientist]

I have to do it over the net, I am in the backwoods of Japan. They don't even balance shafts here, it sucks.

All r32 and most r33 rb26's suffer from the crank collar issue.

correct me if i'm wrong, but that's only for the r32 rb26dett's never on the r33+ rb26dett's1- iirc rb20 trans should bolt on to the 26 block2- rb25 flywheel/clutch 'push' type, late r32 rb26's and up are pull type3- i believe you can use your stock driveshaft, my friend has a stock rb20 in his s13 and he's using the stock driveshaft, i don't see why it wouldn't apply for s14 as well6- i sold some left over parts to someone with an gtr33 skyline vspec, @12 psi i believe he said 306 awhp? somewhere around there to ALL FOUR wheels..most you can boost on stock turbos is 15/16 then the ceramic wheels start to fall apart, not sure how much hp difference each psi can bring but you don't have to do much to get around 400..

I currently have an r33 rb26dett vspec and i'm using the rb26 transmission, it's set at 14ish psi, don't know how much hp i have but i'd say over 3XX for sure. i had to get a custom driveshaft made, gave them the measurements, mine cost around $242 at some driveline shop, i provided one end/flange that attaches to my trans and they basically cut it off the driveshaft, ordered the other flange assembly that bolted on to the differential which cost me around 30ish, (could've saved 30 bucks if i provided it) welded a tube in between the two flanges with a slip-yolk in between. You could save some money if you give them your driveshaft and have them modify it

[Joe]

yes the 20 trans will fir on a 26, but dont.

all RB clutches were push till the R34. then both the NEO RB25 and the RB26 went pull

yes the stock driveshaft will work, but dont put a rb20 trans on a rb26.

[skylinegrl13]

some R33's, mostly earlier ones from what i've heard, do have the crank collar issue, the problem wasn't completely phased out until the R34. i have a 95 RB26 with a short collar.

also, i've seen both push and pull type clutches for the r33, so i guess there are both types.

i have an r33 rb26 trans, all r33's are pull type unless the conversion is done, which is rougly around $100, most of the parts can be ordered here in the states, but one or two parts aren't available here, i got/most of my info from the skyline gts/gtr forum on freshalloy, so the list of parts can be found there

[Carl H]

r32 gtr early transmissions were push then facelift on they were pull.then sometime in the r33 generation they went back to pull then back to push...retarded if you ask me.

[Joe]

so im not crazy! i knew i had seen a push r33 26. lol

[HxC_Nismo]

so im not crazy! i knew i had seen a push r33 26. lol

my r33 rb26 trans is pull style
