Rb26Dett To Rb26De

[nltd]

Hi,

Most will probably say what the f**k are you doing.

but yes, i do want to convert my rb26dett to a 26de.

Reasoning: just finish the build on my 32gtr, and i want to enjoy that. however, i still have a standard rb26 sitting around....along with a standard 72' datsun 240z...so that should clear it up abit more.

I dont ever plan on selling the s30 and im tossing up between keeping it original l24 or going rb. my reasoning towards the rb conversion is that since i dont plan on selling it and keeping the L24. i might as well go all out...

What kind of things would need to be done to convert the standard rb26 to a na screamer. im awayre of the pistons to up the compression. but any thing else?

Buy one from japan.

Autech made a High comp RB26DE in a four door r32 special. Rocky Auto loves em, has heaps.

trying to keep costs to a minimum =\ and buying another engine would be abit pricey.. esp fr rocky auto, and then id have a stock one to sell.. stock ones arent so easy to sell either. ive tried.

Then leave it alone.

Your not going to get away cheap if you want to build an engine...

Gerg_31 was selling a full setup for normally aspirated RB26, see if he still has it but if not I'm sure he'll happily assist with any advice.

Make sure it has pipes like this-

imagine this...

a RB26DE, with super high comp, with HKS V Cam (optional if you want any low end), stupid duration cams, 6 flutes and a redline at 10k in a 240Z...

brap brap brap brap brap brap

I remember a guy on 31club who spent a hideous amount of money on a n/a rb26 and it was very disappointing. I seriously wouldn't bother.

[Dose Pipe Sutututu]

but say if you skimmed the head all the way to a 10:1 surely it wouldn't be "that" bad right?

10k redline N/A ITB would be sick.. and stupid as long duration cams, but of course will need some form of VCT to give it more poke down low.

imagine that with flutes, would sound sick

[nltd]

i would honestly rather keep the Z n/a. and what better engine for it than the rb. i dont really care about the power, my gtr is there for that. Im all down for the screaming high revs bouncing off trees when i go for a drive. i think it would be better if i just na a rb26dett rather than buy a 1 of 200 autech rb26? last i heard they were goin for 6k...IF you can find one. LOL. rb26/30 na would be affordable.. jsut swap over some parts n vwoahlah. (ok maybe not that easy) but within reach. ive been trying to source a autech rb26....not happening.. =\

[GH05T]

well he spent 20k on this engine, dunno if you wana go that far but i agree, if you can get it done for a reasonable cost it would be fun in tunnels.

[nltd]

i pm'd him. hopefully he replies. im hoping to go to his workshop since he is fr sydney, and check out his work. his build showed it got 170rwkw... which isnt much. but from a FR car that weighs 1000kg and an engine that can rev over 9k. mmmmm

Why not RB25DE NEO ?

Why not RB25DE NEO ?

Great option.

It's never going to be a power house like a turbo motor. But this would be a great option. Cheap motor, set it up using headers and ITBs. No need to even open it, besides cams. Enjoy the noise and cruise in a awesome sounding and looking car.

Leave the power to the R.

[nltd]

the only reason going this way is becausei have a spare rb26 long motor at home. no one wants the long motor so i might aswell chuck it in. its missing the turbos and the sump.. which is perfect. since i dont need both. everything else is still there.

[Dose Pipe Sutututu]

DO IT

skimmed the head because the 8.5:1 compression will suck donkey cock, bring it to like 9.5:1 or even more if the pistons don't foul the valves.

then mod the intake plenum and install 6 flutes, bring the rev limiter up to 10k (I'm sure it will spin easily to that safely as it's now making 1/2 the power)

then whack on some retarded long duration cams...

brap brap brap brap hahah
