Hi guys ,
i was looking around the net for 3.5LT cylinder liners and found some in the UK
has anyone bought a set of West wood ?

I've not, but remember you'll need pistons (dur ::) ) but me thinks the head gaskets will be the biggest hurdle.

i know of a guy who makes copper head gaskets lol
Piston "no" ill just get bigger rings lol, i have already have researched them out of the US mate
have a great day
Well keep the forum in the loop if you can.
What 100-101mm pistons are you looking at? The pure cost of doing a big bore is so off putting, but if it could be more realistic, that'd be a great performance upgrade. So long as it's real world reliable, tho.

Some time ago i saw a you tube clip; it was a 164 with a Savail 3.5LT motor
I have always want to build one so I would like to collect the bits so I am can when I rebuild my Q motor
even thought it a 12v.
It should have Plenty of "POWER" to quote Jeremy Clarkson.
cheers
I purchased a block with liners inserted, pistons and head gaskets from Dawie in SA.
PM me if you want
Mine was 24v
Savali 3.5LT 164 https://youtu.be/jJoSx-byP_I
I found this look very cool :D
HP on information from the previous owner of 240 KM. Engine 3.5V6 differs only in the diameter of the sleeve and compression ratio, the rest in 3.0.
3.0 has a sleeve 93mm and 3.5 101

Found this on the 3.5 head gaskets
The gaskets are 2mm thick, at least when I meassure them now after they have been used for a couple of years. The rings are 2.15mm thick now. I was told that they were 2.7mm when they were new, which I sort of doubt. Not that I am a metallurgist or anything, but compressing them from 2.7mm to 2.15mm would take quite a lot of force, and as far as I know the tops aren't torqued hard enough to do that.
don't know if you solved the issue with the head gaskets already, I've got a 3.5 V6 Savali as well, all in pieces but ready for assembly.
Got it from a friend who purchased the engine to fit his HAWK Stratos Replica but the HAWK was sold last year without this engine.
Through a friend who does mainly US cars / engines he got some new specially made head gaskets for a reasonalbe price (71 USD a piece, left and right bank).
I just checked out the gaskets, they are 1.5 mm thick (base layer) the cylinder rings slightly thicker, which is the same as for the old 3.5 gasket (I have one as well).
3 liter gaskets are slightly thicker, 1.8 mm for the base layer and 2.1 mm for the cylinder rings (I got a new set of these as well).
The US gasket supplier (Cometic) used 1.5 mm Reinz base material for the gasket and look OK, only the copper seals for the oil channel are missing and now rubber seal all round is applied but this seems to be not to much of an issue.

Have you emailed the liner manufacturer in your first post to get an idea of costs?
Duk mate
Yes I am waiting for a response
Cheers
I got a response to an equirey:
"We have the 101.00mm in stock @ £90.00 GBP Each. The 100.00mm would have to be a special order @ £120.00 GBP Each."
So about $165 to $220 each at the time of posting.

Finding someone to do the machining on the block is the biggest hurdle IMO.
I agree with LaStregaNera, unless you already have a machinist tucked away somewhere.
There's nothing technically difficult about machining the block. Who can do it with the head studs in, that's probebly the big challenge.
hi
It's going to be a challenge .But that's were the fun is guys
I personally love a good challenge but just in to proceed slowly one job at a time
and it with all come together in the end
If anyone see's parts please fill free to post it.
I'm pretty sure water jackets need welding as well.
I'll take some shots of my block Next week... again, 24v not 12v
A few people over the years on GTV6.com have said that water passages in the heads need to be welded up and moved outwards.
Apparently more effort is needed on the 2 valve heads than the 4 valve heads.
Pistons and head gaskets still look to be the biggest hurdle, in my opinion.
If someone was getting keen, having pistons that raise the gudgeon pin as high as possible and finding/have made suitably longer conrods would help chase more horses out of the stable too.
Just to give this a little nudge.
I emailed Lewis Engines here in SA about some other work I want done and at the same time asked about their ability to bore the Alfa engine with the studs still in place.
They said that they could do such work.
No price was quoted, but as maybe some idea of cost, getting a 6 cylinder engine bored and honed costs $520 and the Alfa block would only need boring.
I assume that is you supplying the bare torn down block ready to bore?

That would be the way I'd go about it, yes.
