I dont talk down on people. I was stating that themadscientist had already proven me wrong.

I dont change my opinion. here let me state it again for you to read:

"I think the RB25 is a great engine, but not THAT great of an engine" as in- its not the ultimat do-anything engine as people were implying.

Threre is no perfect engine, but in my opinion the rb series comes pretty close. Its powerful, reliable, and compact. Oh yeah and a streetable powerband that still has good peak HP.

so yeah, just wondering, has anyone done an RB swap into a 240 on there own, i mean not in a shop? bc i am looking for something for my 240. i bought it from a junk yard and it was pretty gutted. i am debating if i want the red top or the RB25, but if the RB is going to be a behotch to get in i would want to do the sr. so yeah any thoughts?

i would love to come see it when it is done.

like i said I am a fan of the rb series, but i have my doubts about the rb25.

When I see some cold hard facts (i.e. dyno sheets, exact parts list) then i will belive everything you guys are saying.

The RB25DET is just as easy as the SR is to get in, no real modification required....read the FAQ section I have posted on my site, it may answer some questions.

Night360-672-2415 Call if you have any questions.


Cool, you see, you have me more convinced now.

EDIT: it does look a tad harder to install if you are lifting the engine into the car from underneth.

Plastic would shred instantly unless it was super plastic. I have a R33 turbo....not the new R34 T28's.....not looking for a fight, just saying that there is no way the wheel is plastic.

The wheel in the early model R33 GTS-T turbo is P.L.A.S.T.I.C. It is obviously not Matchbox car window plastic, call it "resin" or "composite", whatever but it's just a fancy word for plastic. You have the later model R33 GTS-T turbo, the superior model, be glad, trust me. I know you are having to go on faith but I held it in my hand, I poked it, twisted it, threw it against the wall, Mad knows plastic when he sees it. Nissan quickly axed that idea, good move.

lol. Why is "plastic" given such a negative connotation? There are many mechanical components that are better suited for certain materials. Take ceramics for instance; they have a much higher melting point than metals, and thus are better suited for exteme temperature environments. Whether it's plastic, ceramic, or a composite of the two or more materials, is irrelevent to whether it does what it's meant to do; function and function consistently.

whatever it is, i read it is a nusance when boosting on the stock turbo and the concencus is that it should be replaced when you can do it.

when picking up a RB clip, how would you know if it has a plastic or metal compressor turbine without opening up the motor (if possible)?

not to call you stupid, but if you didn't know there are WAY more parts out there for the CA18DET at your local autozone than the SR. Heck you can't even get an SE-R (sr20de) oilfilter at the local nissan dealership in Merritti island.

the CA's all use the same headgasket, bearings, oil pump, waterpump, headbolts, cams, timing belt, CAS, Ignitor, lifters, rods, rings, block (with a slight mod) gasket set..... need I go on?

Try getting an SR waterpump at autozone.......

I bought a sr20de pump. it is going to work once i adjust where the pulley rides. it will take me about 2 minutes to do that. the ca18et has the same cam as the ca18det? heheh i'm just messin with you. so go for the rb.if i could do it over again??? i'd have a ca18det.if i could do it crazier? a q45 v8. or a vg30det with older style manifolds and have the tubo up front so that i could work on it. does anyone have the pic of the s13 with 350ci small block in it?that is cool.

i didn't get a sr20det to be different. i did it because it was cheap. the rb is neat. i can't go back now and change what i have done. i learned to work on the sr. i have lots of money invested already in the sr series. but i am not going to build my sr untill i have the stuff to make 450rwhp. if it blows, i don't give a crap. they are cheap and very easy to replace. the sr is easy to make power with, as is any motor. i have a friend that does everything himself. the thing has a t3t04e turbo and the stock manifold! he is a budget master!
