Whats the pros and cons on sr20 and beams 3s
I've got nothing yet looking for a project car been looking at Sr20 rb25 beams 3s just something different not the normal v8 buildsd-peg wrote:Surely an SR20 in a mk2 would be hellishly more complex due to being longitudinally mounted whereas the 3S is transverse to start with? It will mean a new sump, baffling and pick up (available parts but will need sourcing)
EVERYTHING for the 3S will fit. No gearbox adapters, no special mounts, no special driveshafts etc.
I'm not knocking the SR20, it's a great engine. Just seems pointless when there is already a great engine to throw in there. The Beams to turbo would be a crazy amount of work. If you're looking for a 'better' 3S then perhaps start with a gen4 engine (found in the Caldina).

I've only just for quickness found these on eBay USA but there are UK companies that could source and install one for you.
In terms of 'better' it's newer, coil on plug, more modern etc. however, it depends on what you want to do with it. The Gen4's are not as strong as the earlier engine in piston and rod terms.
The beams turbo can and has been done. It is another pricey swap though, which ever way you look here you'll be spending a lot of money.
I wonder why you'd simply not go the Gen2 or 3 3SGTE turbo swap which will be out of the box and comparatively cheap. Unless of course, you already have a Beams
Dan, the Gen 4 has not been found to be weaker at all than the Gen 3 in any terms, in fact there are many Gen 4's over the pond running 400+ reliably with an unopened engine. Material science moved on a fair amount with the advent of the Beams and Gen 4, both of which use the same bottom end and both took advantage by having lighter rods which haven't found their limit yet. As good as the Gen 3 is, the Gen 4 is far superior, as you'd expect from a more modern engined-peg wrote:

I know exactly the thread you're referring to, you know how much boost that guy was running which then spiked don't you?! I'm sorry Jim but you're just quoting a very early thread (think it was 2008)!jimGTS wrote:sinjen wrote:Dan, the Gen 4 has not been found to be weaker at all than the Gen 3 in any terms, in fact there are many Gen 4's over the pond running 400+ reliably with an unopened engine.

i take it you dont look at any of the US forums??
the rods are the weakest area of the gen4 and have BLOWN straight through sumps and blocks!! the fact this has happened multipal times does not feel me with confidence.
ever seen a gen3 blown to actual pieces?
