Hi,

For the future, I would like to build a turbo engine which is bigger than 76-78mm.... must be cheap!
I have read people bore std G13B out to 76mm with success, but this will make bore meat too thin.

So, I'm thinking of machining out OEM cast sleeves and install new set of sleeves.
Can anyone tell me how to do this?
I read GT_,s post below link.
http://www.teamswift.net/viewtopic.php?f=6&t=47209&start=50

I can get hold of 75mm bore as well as 80mm bore but externally same size.
So if I use this sleeves, I can bore it out to 80mm and it will be safe to turbo it as they have turbo engine with this bore size.
It is Rover K-series engine. I'm still trying to find out their bore centre to centre.

Has anyone tried similar?

Cheers
Atchi

Hi,

I got 1 off my friend.
It has 87mm outside diameter and I will need to shave 1.5mm to able to fit sleeves side by side for 84mm spacing.
I arranged all this machining in my friendly machine shop for few tins of chocolates and cockies!

Oh, Std K-series sleeves are £20 each or $30 to you people.

Cheers
Atchi

Hi,

I have checked few bits and bobs.
K-sereis 1.4 engine used to come with 2 different types of liners but both of the 75mm bore.
Both of them is 82mm OD at lower section but top has 87mm.
Older liner has 87mm bit which is 6mm from top may suit better than the other type which has almost approx.40mm from top is 87mm.

[urImage

Small lip liner is stronger one as my friend has been running "BIG" boost with it. I think he said almost as much as 30psi. Bigger lip is the one you can buy on ebay.

What I would like to know is that which type will be better for my application?
Bigger lip, I will have to machine a lot and will take out block deeper but it will have a good location and hopefully strong top end. But these are poorer quality material compares to small lip liners.

If I go for small lip ones, I can only get them in 2nd hand.

Cheers
Atchi

Hi,

I'm still in research and collecting part stage at the moment but here goes.

I have 2 sets of std 2nd hand Vitara pistons.
So, I did some measuring and compare it to std G13B.

Here goes the result.
Left is Vitara
Image

Piston is almost 1mm difference.
Image

Vitara piston has 5.5mm -1mm ruler thickness. So it is 4.5mm deeper than std.
Image

Liner length is 132mm length, so I will need to make it shorter, I think.
Image

Just checked if piston goes in OK or not.... it's in!
Image

It is very good fit as it was pressurised when I installed piston into K-liner.

I only have 1 liner now, so I will need ask my mate to dig out rest of them!

Cheers
Atchi

Keep up the good work Atchi.

Has anyone suggested Kubota tractor sleeves to you?

Hi Dattman,

No, I didn't think about Kubota tractors.
I don't think we have them in UK.

I have 76mm in order too and when I bore it out to that size, thickness of wall will be 3mm.
So I think it will be OK. Then again, I think I can try with 75mm first :huh: .

Cheers
Atchi
