Looks good man!

I know you mentioned using standard Altezza 4-2-1, but is there any chance that the exhaust manifold you've got there would fit with modification at some point? Or are the port spacings etc a bit different?

The port spacings are different, but I may have to do it anyway. The Altezza manifold won't clear the starter motor, so I'll get a flange cut up and try to make the old ones fit.

The problem is that I think the old manifold loses a lot of torque... Since it has 2" primaries, 2.25 secondries and a 3" collector. It should be just as good as a standard manifold for the time being though.

**Touches wood**

I'd touchin' my wood if this was my car too!

Was having a pplay around with my mrs' caldina on the weekend, and I couldn't see any dizzy, I assume spark is controlled by the ecu? Unless its tucked around on the inlet side somewhere?

What have you decided to do in the ECU department?

this just looks way too much like plug in play for something on oldschool. something will have to go wrong and you will have to take it apart and re do everything backwards/lefthanded. :rolleyes::wink:

plug in play lol, yea right.

its not mitzi lego

What Jase means is, yes, it's all plug and play thanks to my pro as fuck engineered custom adapters in the form of mounts / drive gears / manifolds / everything.

They have no Dizzy, it's all run by the ECU through a crank angle sensor and coils, but we've done it differently. Jase has machined bits for me so the Gen3 Dizzy would slot into the back of the head, meaning the old wiring and ECU could be used.

He also did a mint job of the intake cam gear, which is a bit more complex than your average adj gear...

So I spose, after a few days worth of Machining, welding and other custom work it is now Plug and Play (Fingers crossed).

Oh, I cranked it over today as well... But the battery and jumper battery were too flat to get the oil pressure up (with the plugs in).

Cheers man!

Got approximate lengths for the headers now.

Primaries - 450mm from the flange to the start of the collector, 45MM ID.

4-2 Collectors - ~100mm long, 45mm ID entries > 50mm Exit

Secondaries - 340mm from collector exit to collector entry - 50mm.

2-1 Collector - ~100mm long, 50mm entries > 55mm exit

Taper from 55-60mm 100MM long, then 2.5" for the rest of the exhaust.

so is that the ideal lenghts for high rpm??

i would like to make the collectors a little bit longer if pos?
