Thread: Time to dispel some of the crap

Its was thre as it had to be because of homologation rules.

Nisom thrrew the N1 cams, pistons, valves and springs in the bin. They replaced them with their own.

Last time i enquired, its was 4100 AUD (380,000yen) per camshaft to be replicated from their motorsport catalogue. After that - i didnt bother asking about pistons.

very funny thread, i await the outcome of before and after testing on an actual dyno, in an actual car. Just because a flowbench tells you a head can flow xxxhp doesn't mean it will once you put things like, oh i don't know valves back in it.

If the difference between the 20ve and 16ve N1 were the bore then there could be a discussion around manifolds and head flows but that's not the case. The way the 1.6L consume's air is completely different. That's why timing is so different and that's why the IM can make power on a 1.6 but not a 2.0

All i ask is to put the head on a motor in a car, dyno then put on what ever intake and header you want then dyno again.

Oh yeah, make sure you have the cams that have the lift to equal your flow bench highest flow numbers.

Not really though. This head has a fair bit more work. The kelfords head flowed 270something from memory? where ours flowed over 300cfm. both on 86mm bores

I would like to go through my head next , I already have sleeved block I am running 87mm right now but when I do the head I want to throw in my 90MM pistons as well to get to 2.2L , I think it would rock ....then I can try my 20V cams with it as well

Subscribed for dyno numbers

i am ready to see some numbers!
great work on the head in the pictures!!

X2 any updates?

head is with a fellow member. Numbers should not be far off

can you share the specs of the motor or does the member not want that?
