This week in the shop… Sneaky Evo 8

So how do we do that then?
Well you can start off by increasing the displacement (there’s no replacement for displacement as the boys with the yank tanks say) by swapping out the 1997cc (85mm bore x 88mm stroke std) bottom end of the 4G63 block for the 2351cc (86.5mm x 100mm) of the 4G64 from the Eclipse (ya the one in 2FAST 2FURIOUS yuck but it was good for something). Not a bad start I suppose but just not good enough we’ll give it a little more with a Brian Crower billet crank increasing the stroke to 106mm when combined with Crower rods, some custom CP pistons and a Cometic metal head gasket bring us up to about 2.6l (now that’s a bit better).

A big bottom needs a big mouth so the help the engine breathe we had to do a little to the head. All Crower in the head this time springs with titanium (ooh titanium) retainers kit, 1mm oversized intake and exhaust valves. All finished off with a big lumpy stick aka a “Stage 3″ 280 degree Crower camshaft to open the mouth a little more.

As some may have noticed the girls with the big bottoms often wear big jewelery. So we given this girl a nice Garrett GT35 earing hanging off an equal length split-pulse hoop which feeds around through a PWR rad to the AMS VSR intake. Also included in the ensemble is an AMS fuel rail with 1000cc injectors and an OS Giken STR clutch.

All this is controlled by a Haltech PS1000 ecu otherwise you might as well chuck the whole lot in the skip without decent engine management.

After all that looking at the cars innocent smile and rosey red cheeks you’d never realise that there is a screaming bunny boiler underneath. Be careful she could take a leg off remember she’s sneaky.

Will update after the run in and a little bit more work with figures. P.S. I’m gonna be in so much trouble over the “big bottoms”.
