rb26de 240z
« on: April 07, 2011, 01:58:30 AM »
Hi,
wanting a project. Considering a rb26de into a 1981 or 84 240z.

Iv heard the rb26de engines are super rare but can I just strip the turbo bits off a DETT and change the compression or is there a lot more to it than that.

wouldnt mind putting in a DETT if it was going to be considerably easier/cheaper but would prefer the NA just for something different.

any thoughts would be awesome.
thanks

Just buy an RB25 and stick a 26 crank in it since you presumably want 2wd.   but why not just put the Rb26DETT in it - would not be easier or cheaper though. For real fun get a VH41.

A 240Z is 1970 to 1978! also there were 260Z's an 280Z's which went up untill 1979 and there is no such thing as a 81-84 240Z or do you mean the ugly(well ugly when compared to a 240Z) 280ZX? they are 1979 to 1983!

Anyway a RB26DE or DETT is going to cost heaps no matter how you go and with the same money put into a R33 RB25DE you will have more power in N/A form easly!
Your cheapest option to get good power is a RB20 or 25DET conversion but then even with standard turbo power you will need a suspension and brake upgrade. So lots to weigh up there

Yeah that's a RB30 with a RB26 head triple carb.

Rocky Auto Carbon S30 if you wanna read more about it, there's heaps of info out there.

That Rocky Auto car is awesome!
Only thing is you were commenting on if something was cheaper so kinda hints that you dont have alot to spend? and geting even half decent power from a N/A costs quite alot and so does being different most of the time.
Carbs are a waste of time an effort in this day an age and if your kidding yourself that using them is being different in a 240Z all it will do is cause you problems! and in NZ having a 240Z with a RB in it would be different enough in itself.
RB26DE engines hardly ever come up for sale in NZ but the RB26DETT is available every day for around $4000 for a complete motor conversion and you can recover some costs selling off the turbos if you were to go N/A.
For a budget setup with good power I would go for RB30 block 10:1 comp, std RB26DETT head and ITB's etc etc for around 150rwkw or if it was a big $ build I would go full dry sump RB26DETT with custom crank, alloy rods, forged pistons for 12.5:1 comp, full cnc ported head, 1mm oversize valves, huge cams, custom intake manifold with big custom slide throttles and all the other jazz for maybe 220rwkw.
Do you have a car lined up?

would the triple carb setup have issues when running hot?  only sucking in hot air on the input side?

Not really - turbos have a problem with high intake temps because the turbo (which is a compressor) heats the air even more.

Yes and no! you need some good heat sheilding either way no matter what! but yes carbs dont take as well to heat soak as injecton of the same nature does!

Ummm? NO! yes they can really! as a turbo can have the option of a intercooler yet a carby can not!
