RB20DET motor

[rbsileighty]

Does anyone know if some of these japanese salvage places (such as Venus, Jarco, Night etc) would sell the motor by itself with no wiring, trans, or intercooler? If so how much should it be going for?

hey i jus saw one on ebay today for 850 jsu engine and transmission i believe said less then 60k kilometers. could be something to checkout. only thing i have against is its on ebay. which is usuallg buy at own risk. well its an option

I've got a spare engine, its been stripped down though. i was going to do a stroker out of it but I can sell it too you for the right price, if your interested that is.

Reason I'm asking is because I was thinking of going ahead and getting the Haltech and RB25 trans when I get the motor. We will see what happens around April. I already have access to a parted out RB20, but thanks for the offer.

hmmm...haltech and rb25trans.....sounds like a fun ride. rbsileighty are u gonna do the 8.5 C/R pistons too. I wish somone would do them to see the power diff between them and the 9.0 stock. IF its big enuff i might go for that instead.

The 20 is already 8.5:1. What happens has a lot to do on how nice Uncle Sam decides to be with tax returns. I would like to do suspension as well, so we will see how "enhanced" the motor goes in when I find what I'm getting back.

This also makes me think, what is the difference between the port/bolt design of the intake side of the 25 and 20? Someone with both heads should take a pic of both motors intake sides to see what it would take to put the Greddy intake plenum on the 20. If the bolts are different and the ports are bigger, maybe it would be possible to make a spacer/adaptor that moves the bolt locations (like the nice wheel spacers with bolts in both directions) and a tapered bore if the ports are that much different so they would match. Just a thought.

DOH...i had em reversed...sorry

[gani]

i think unstable hybrids make an intake plenum for the rb20...

[PROJECTRB240SX]

I HAVE ALL THE PARTS TO IT, IT JUST NEEDS GASKETS AND BEARINGS.

[PROJECTRB240SX]

I HAVE BOTH ENGINES AND THE RB25 INTAKE PORTS ARE LONGER, THE WATER INLETS ARE DIFFERENT, AND THE BOLT PATTERN IS TOTALLY OFF. I HAVE PICTURES BUT I HAVEN'T HAD THE TIME TO UPLOAD THEM. WHEN I GET A CHANCE I'LL POST THEM.

[rbsileighty]

What should the safe max power for a 20 on pump gas (92-3)? This is not running water/alcohol injection or anthing similar.

I have an RB25DET longblock for sale if you're interested in that.. very clean too!
