Even fully built and everything, there are a lot of horror stories pertaining to its long term reliability. And thats just scary when you put a ton of money into it and dont know when itll fail, like cracked block, oil starvation etc. And about 700 hp is about its theoritical limit, and torque wont be extremely high
The nature of the low stroke L6 is something to be desired by everyone, how quickly itll reach high rpms and how awesome it pulls. Ideally good choice on skipping the 4 banger, and not going with the typical ohv.
Good luck though, i wont even say what engine i would be using if I had 10 - 15k, but chances are i wouldnt continue with the rb25. I wouldnt not consider the rb25 a "waste" whatsoever in its current stage of life and how cheap it was for me to do the swap, and how it hasnt had a single issue yet.
And i think for me it was the best bang for the buck, but fully built- might be a risk im not willing to take.

Why I decided to go RB25? I had enough buddies in Japan that are running stock bottom end RB25 with stock HG and ARP studs pushing over 600hp on Holset HX40 turbo.
I've ridden in a couple LS1 swapped S14 and I wasnt too impressed. I like boosted engines better. Then again, when you've have a 500 hp'd SR and you sit in a stock LS swapped S14, it wont really be exciting.
My goals is 400-450 hp RB. I think for that power level, an RB25 would just be barely breaking a sweat, while the SR is pushed to its limit.
