X16XE is an Ecotec version of the GM Family 1 engine. Designed by Opel and used on Daewoos, Vauxhalls, Fiats, Chevrolets

With sodium-filled exhaust valves and 10.5 compression, they make 105 hp @ 1.6 liters. So not as much as the old Nissan GA16DE with Variable Valve Timing, but very good nonetheless

camshaft are very mild but they can with a cam swap match the ca18de
as they are a Lotus designed head

Quote:
CYLINDER HEAD Best cylinder head Price: Haggle Where: Breaker's yard Vauxhall has tweaked the cylinder head design several times over the past 13 years. The early C16XE head (casting number: 90472726) is a cracker as it uses much larger ports, whereas the later X14XE and X16XE use smaller and different shaped ports that peg the power back. The very latest head casting (number: 90400187) uses triangular inlet ports, which work a lot better, gaining up to 12bp. Gas-flowed cylinder head Where: www.sbdev.co.uk The standard cylinder head is very efficient and will flow up to 180bhp on 1600 and 150bhp on a 1400 before headwork is required. Beyond the point SB Developments can supply a flowed item with heavily modified exhaust ports (they weld them up then re-machine them to alter the shape), new valves and guides to gain up to 20bhp.


215hp atw bad sounds but about 240hp ate

 Re: NOS x16xe head
What makes 215 hp?

The X16XE engine makes 105 hp stock. If the unmodified head is good for 180 hp, that's tremendously excellent. I'm guessing you'd need intake, cams and exhaust changes to make 180hp -- and rev it up really really high

What does it take to bolt one of these on an A12 block?

 Re: NOS x16xe head
Thats a fully worked unit that makes as much as Steve Newings ca18de but with less capacity

Just cams, and headers frees them up then modded inlets or Itbs or carbs etc

The bolt holes all line up to an A series and so do the bore spacings
even water jackets line up, oil passage is same mods as mazda head
and head even covers side oil drain & pusrod holes on the block
without blockind this area using the mazda head as head casting
has extra area to cover this so its an awesome alternative.

The factory cams are very restrictive to not compete with other vauxhalls
