Default 2.5 Axis Stage 2 bottom end.... any good??

Hey guys,

Im wanting to swap out my V7 2ltr for one of these.

Anyone here run this block and what are your opinions, quality/performance etc?
I was going to match it to a 7cm Green and then maybe swap the hotside for an 8cm and note the difference.

What HP/torque will this take?

Cheers

Frayz

Axis motors are great and few people have had an issue with them. Do some SEARCHING and you will find plenty of people on here sporting an Axis motor with great succes. I myself am in the debate of buying a 2.5 shortblock and building a hybrid or purchasing a stage 2 motor from axis

Frayz,

I'm just wondering why do you want this motor, did u blow up ur motor or you just want that extra .5L of displacement? I'm pretty sure your current motor can handle the green turbo, is this the same V7 motor that the Japanese get, with forged internals?

Yes mate my current motor will handle a green. However i want the low down grunt from the 2.5 not to mention the extra spool on bigger turbos.

My STI 7 EJ207 has the forged internals but im convinced 2.5 is the way forward. You only have to look at the area under the graph to realise its gotta be a better setup.

Im not totally sold on the Axis route so i was going to build my own.

EJ257 SCD block
EJ257 sti forged crank
Wiseco pistons
Crower rods
ACL baerings
ARP studs
Worked heads
Stock cams

Think that should be strong enough for 500bhp???

If I would get there shortblock it would be the stage 3. its an extra 1500 or so but well worth it for all the extra stuff you get.

Maybe but if im 100% honest id rather build it myself.

I build engines for a living, but the stg2 interested me due to its price. Im hopefully looking at a bigger spec build now so would like to do it myself.

Its just that everything is so damn expensive this side of the pond
