i remember this being a hot topic of discussion several months ago. the main arguement against doing it (as far as i could tell) was all the custom fabrication that needed to be done, but in light of new developments like mckinney motorsports' mount kit, this has become a fairly bolt in affair... what's everyone's thoughts on this swap? i've been debating which way i want to go, either s14 sr20 or an rb25... also, what's the stock turbo on the rb25? t3?

 

i was concidering it myself, something different but now i`m thinking about finding a 300zr front clip and dropping a rb30det (or is it an "et"? need to do more research obviously)

 

i believe the stock turbo is a t3 and its rated at 250 i think. definetly go RB if u want ultimate potential. probably cheaper to go sr20 but the newer sr20's are more expensive. rb26 can go in too but u need an rb25 tranny and rb25 oil pan cuz the rb26 pan would hang too low on a 240. call shaun at upgrade performance (www.upgradeperformance.com) he's done rb25's before and i think he was quoting 5500 out the door for a swap. id say rb all the way. good luck with whatever u choose.

 

i always thought that on stock block, the sr20det > rb25det, potentially. Of course, in the end w/ some rebuilding, the added displacement will help. But who has the $$ to actually do that?

What's the rb25det tranny capable of?

It's kinda funny how ppl wanna be "different" and they now have a kit to make it plug and play.
I dunno, to each his own.

 

got nothing to do with being different. it's got to do with an inline 6 vs. an inline 4

its got to do with t25 flange vs. t3 flange out of the box

its got to do with torque

its got to do with displacement

and now that they have mount kits, its not really different, is it?

 

engine code on 300zx motors is vg30dett

 

rb30 is a hybrid bastardization of an rb30de (or e i dont remember) block and rb25 or 26 head (dont know which or if both work). dont know anything except that its been done. aussie style.

 

what car did the rb30 come in? i've heard the engine code thrown around once or twice...

 

RB30 was in the commadore me thinks..... whatever it is its a big nissan sedan....

 

allow me to correct myself...

i meant an rb20det, as found in the japanese (and other right hand drive countries) 200zr. the rb30e was found in the commodor and can have the rb25 or 26 head swapped onto it, depending on your turboing desires. the rb20det was a i-6 2.0 liter, with @214 hp at the wheels and all the potential of it`s offspring (rb series motors) and i just read on the www that an rb30 will bolt right into an s14 with an r32 crossmember, jfyi.

also there was a 300zr, but it had a vg30xxxx motor

pic is an rb20det in a 200zr

vg30dett is the engine code for 90-96 300zx, 84-89 (which is what i have) is a det.
