Pistons + Rods

[Yaris WRC]

If any one wants pistons and rods for turboing or NA tuning ELPrototypes in Cali USA can do them cheaper than it would be in the UK and in a shorter period of time, UK time for custom pistons is 14 weeks, ELP can have them to your door in 5 weeks.

there website is down so

Tell them Nick told you about internals

hi mate can they do oversized pistions too, cos im thinking of increasing the displacement in the future?

Cheers

top banana!

[Yaris WRC]

yes they can ...but the inside of the yaris block has a special coatin i think its Nickacil and it all needs to be re-coated etc if you oversize . its a lot of work basically

[SuperRetard]

Got to say, the similarities between the 1NZFE/2NZFE and motorcycle engines just keep stacking up:

1) oversquare (more bore than stroke, revs better)

2) nikasil coated cylinders

3) chain-driven cams

[Yaris WRC]

if we could only get them to rev out to 10000 RPM aswell

[Nizan]

ok enough of that im getting excited now :P

[SuperRetard]

Yeah, my bike engine revs to 8500rpm before the limiter, and the race version revs to 10,000rpm!

That's a bore'n'stroke of: 78mm x 67.2mm

Compression ratio of: 9.6:1

Compare that to the 1.3 Yaris 2NZ-FE: 75mm x 73.5mm

Compression ratio of: 10.5:1

Okay, the stroke is 5mm longer, but I reckon it could still rev to 7,500rpm safely... I don't know - but it makes sense!

[Nizan]

it does make sence i think

my K3 Gixer6 Reved to around 15K what sort of bore n stroke do they have mate??

[SuperRetard]

That is one oversquare motor!

67.0mm x 42.5mm and 15,500rpm rev-limit... proper little screamer!
