Which should i get ? engine transplant

[PHaT MR30]

Ok so i am definatelly going to be transplating an RB of some sort into my MR30 skyline.

question is which one?

and RB20DET is around $2100 for engine/gbox/loom/ecu

as opposed to an RB25DET at more like $4500 for the same

have your say on why i should should not go with either one of these

[Rezz]

I say go the RB25... I love the mid-eighties Skylines, and to see a modded RB25 in an MR30 would be the dogs bollox... I guess I say that coz the RB20 was introduced in the R31, the R30`s replacement. But to have an engine from 2 generations up, would be the best old/new mix IMO. More power and a newer(ish) engine than the RB20 goes without saying.

cool thanks keep them comming, i really want to knowwhat ppl rate the engine as. i would only be looking at the ECCS R32 RB20 if i was to get one of these.

the car will also be changing, get rid of the pimp chromey, run some gold P1s and a front bar that i am hoping is getting made right about now

show your thoughts

I imagine the gearbox would have to be alot bloody stronger in the RB25 than the RB20, but i have heard they don't take much over 350-400rwhp could be wrong

Thats enough though, isn`t it?

Love the Gold Buddy Club P1 idea...

[PHaT MR30]

yeh but why is the box so much more expensive than the R32 box like $1000 more ($250 as opposed to $1250)

ive got some import DR30 taillights on the way and a JSS front bar comming eventually

I heard the rb25 box's are good for 700hp ??

RB25... i personally didn't like the RB20 a great deal.

and my gearbox is going along quite fine with over 200rwkw... Nothing wrong with it yet lol

I'm not sure if it's a 20 or 25 box, but it's lasting good.

touch wood.

where ya getting a 25 from?

(mine might be for sale for the right price...)

[PHaT MR30]

engine will be comming from japan in about 6 weeks through an importer i know i can trust

thats not saying i can't trust you, some importers are just plain dodgy though

[R31Nismoid]

mmm.. mines running in car lol!

not on a boat

[PHaT MR30]

maybe the gearboxes can handle 700hp im not really sure, thats why im asking you guys!

only reson i mentioned gearbox is cos Sub Zero tossed theirs cos it was getting weak?

Hmm, in an MR30 I'd be inclined to fit an SR20DET myself. But of the RB25/RB20, I dunno, if you bought the rb20 you'd have more money left to mod it, if you got the RB25 you'd have a slightly better base to begin with.

Too close to call. The RB20DET is more bang for your buck, but the RB2DET is definitely a superior engine.

cheers,

Dude i thought about the SR then went nahh alot of work. Doh! just realised that instead of using the Skyline crossmember us a pintara crossmember... piece of piss!

why didn't i think of that!

i can get heaps more stuff for SRs and the like

can i change the poll to include an SR?

[Chef_32]

the gearbox on my friends 33 is holding well at 250rwkw.

[PHaT MR30]

Yeh well all in all i think the RB25 is the thing to have... hmm wonder if i can get a NEO?
