20g or st420?
hi,which is best for spool and power on a 2ltr.(non avcs)
the st420 is a turbo that area 52 motorsport supply but dont know too much about it.
the 20g in question is af td05 20g.
any thoughts guys
dont want to break the 400 mark but would like to get fairly close?
both options would be a used turbo.

20G is great turbo and should will make around 360-380bhp on V-power or T99,400bhp is possible
About the ST420 not sure,don't tried this turbo and don't know how will perform.
Those threads hope help

thanks for the info jura....i think the st420 i was thinking about buying made 400 bhp.BUT at 2bar!(on a 2ltr)
i dont know what they are capable of running but certainly puts me off purchasing it.
i think some of the later af 20g come with a billet wheel,and do they come supplied differently for a 2.5 or 2ltr,or is it the same turbo?

20G should come with same billet wheel,but for sure i would speak with the Andy F about the his 20G
What you are mean about the 2.0L and 2.5L difference is probably down to size of the exhaust housing,bigger exhaust housing will suit the 2.5L,smaller exhaust housing will suit the 2.0L

TD05-20G will be more suited to the 2.0L,TD06-20G will be more suited 2.5L.
Only US guys using bigger exhaust housing on the 20G,you will hardly buy them here in UK,if yes will be import 20G
TD05-20G will be best bet and if its possible billet will be good too,speak to the Andy F about the billet upgrade to the 20G

Yeah the owner said it as an Andy Forrest turbo but didn't know if it was a billet one or not. What do they spool like in comparison and what power are they good for on a 2.0 mon avs?

Hi gents was wondering if anyone could answer this for me, I have a Andy Forest td05 20g with Forge actuator but it's so laggy on my 2.0l and it's is an older model now was wondering if it could be changed into a billet?
Any help would be great

i have AF TD05 20G, bought it of a member on here, the turbo made over 400 on his 2.0l and currently at 366 on my 2.5l but thats due to injectors so i should see more power once i have 740cc.

I've seen a few posts where people say their 20G is very laggy. I don't understand it though, I run a AF 20G and don't find it laggy one bit, infact after fitting it along with GT spec manifold and up pipe it spools quicker than my old VF28.
And now with a splash of meth in the mix to bring up the torque Its fantastic, great turbo for the money IMO.
