Swapping Rb25de To Rb25det

[1R34SON]

Anyone done it that can give advice? I love my R34 and plan on keeping it for a while, I dont want to just buy a GTT. How expensive is it to swap entire motors? cost of motor or cut off etc. Id convert it but i think it will perform better with a motor swap. Conversion might just make the RB25DE motor struggle ay?

Its pretty expensive. I was looking at doing it to my R33, and decided I'd be saving money by selling it and buying an R34 GTT. So that gives you a bit of an idea

my advice is as follows and i'm speaking on the matter cos i did it

if you really want to upgrade to turbo

just buy a turbo kit and put it on the motor yourself

i am running an RB20de+T and it hammers nice and hard, and because of the high compression cylinders i still keep the lower torque and boost is basically instant, as instant as a turbo can be...

keep in mind, RB engines keep the same block, so the oil feed/return lines are already there they're just plugged up

it's not THAT hard to do, not somehting i would rush out to do again though,

but the results are, my rb20 will beat rb25., and most important of all, it's reliable as anything,

i love my RB20de+T

free revving, high compression, instant boost response,

well i bascially did the whole RB25de to RB25det conversion....mine cost me a total of maybe 4k including engine? i seriously don't think its too challenging to transplant an engine as my mechanic did it in 2 days hahaha but yeah i mean the turbo motor is cool ill never go back my next plans is doing a 26 conversion or a RB30 but overall im happy wiht it i still got hte NA gear box diff in there but with the brake rotors etc.... i just redrilled them to 4 stud *done by mechanical engineering place* so i save some coin there retaining 4 stud ! and R33-GTS is weak ! hahah nah jk i guess everyone has different ways of doing stuff lol

[NISZILA]

lol Chi. The difference is I was looking at changing the engine, gearbox, diff and also doing five stud conversion with bigger brakes. With all of that cost I just figured I'd buy a new car

what i dont get it is if turbos have 5 stud patterns why is mine a N/A 5 stud?
