Vl Commo Engine

[blind_elk]

There's "technically" no such engine. They are hybrids, achieved by bolting the DE(T) head from (usually) a RB25 onto a RB30 block.

ok...

lets say i have a RB30E motor

which is SOHC and i wanted to change turn this motor into a DOHC

can i do this? how? and with RB25/26 DOHC's?

also, the rocker cover... do you use the RB25/26 covers?

go ask member cubes

he has done this himself and has a very handy pdf guide on what to do and what not to do

search is ur best friend - look under forced induction section for a whole shit load of stuff about it

[Tebie]

oh yeah

ive found that now

wicked!

[Flash89]

what i dont get is why it went from a 3l to a 2l and the GTRs being 2.6l

[342Four]

what do u mean gordo?

[Bl4cK32]

nissan sold the 3lt design to holden and that meant not using it in their own cars hence all the lower variants...

Secondly dont bother cubes with q's as it gets boring answering the 50 pm's a week about the 3lt. DO research. It will cost u just under 10k if u skimp on all parts, more if u go nuts. building motors for cars that lose value aint fun

thats what i thought, i thought it would be rb30de

but apparently the rb30de is something completely different....

the picture below is a rb30de i believe

that pic of the motor with the redtop, iv read up on these they are a racing engine

hence the triple webbers hanging off the side, were used in sprint cars, track cars etc..

there is a web site about it, the one i seen was producing 300hp natually asperated.

im sure no one is purposely trying to annoy cubes by asking questions,

and i mean there is only some much information you can find by researching and if there is any other questions to ask, who better to ask than someone who actually has an idea on what they are talking about?

that might be a very rare rb24s which indeed is a race engine (have a look at wikipedia - they have something about it, maybe?)

its a rb20 that had a gtr crank etc etc in it

the carbs meant that it could rev harder or something - and yeah it made like 300hp at some crazy rpm

taken from wikipedia:

This is a relatively unknown engine, as it was not produced for the Japanese domestic market. These were fitted to some left hand drive Nissan Cefiros exported from Japan new. Mechanically it is made from an RB30E head, RB25DE/DET block and RB20DE/DET crank with 34 mm height pistons. This engine used carburretors instead of the Nissan ECCS fuel injection system. This has the outcome of it being able to rev harder than the RB25DE/DET (as it has the same stroke as the RB20DE/DET) as well as being almost the same displacment as the RB25DE/DET. A common modification is to fit a twin cam head from other RB series motors while retaining the carburreted set-up. The standard single cam form produced 141 PS @ 5000 rpm and 20.1 kgf·m of torque @ 4,400 rpm.
