So tuners, if you guys could shed some light. Which engine would be more reliable/economical for everyday use in a c33?

RB25
cheaper engine, cheaper parts, more common

Economical as a daily doesn't really apply to these engines. Yes the 25 is cheaper to run,maintain and repair but if you're going from a NA to DET as a daily then you might be in for a rude awakening.

I don't use mine as a daily but for mileage on 1bar it's pretty good I think compared to a gas hungry evo or sti.

buy a rb25 and use a rb26 crankshaft in it.....simple stroker kit....

lol hear what you're calling simple. the parts and money to get that running.
S1 Rb25, decent engine, nice set of upgrades available by ace shops

if i was to use the 26 crank on the rb25det what other mods i may have to do to keep it running???

26 rods and pistons one time unless you get the NEO RB25DET. Those carry same rods and pistons as 26(proven, i have both 26 and 25 rods/pistons and same part number also from my last build...NEO 25 that is)

Then u need headgasket once you scrap and well, a piggyback for proper tuneup.

The best thing to do is buy a STOCK 25, leave it stock, run a decent turbo like a gt30 and emanage and run 14psi....you wont really want more. You might just need a walbro fuel pump, front mount intercooler and 3" exhaust for best results.

I ran a neo 25 stock on a t67 for 2 years, never had to scrap the engine, just had to change turbo to a gt40 and still no issues, but a big difference in power
