 Post subject: Big Bore Sleeves
PostPosted: Sat Aug 02, 2003 12:19 pm 
Hi folks. I have started installing Darton sleeves in Hondas. I have been thinking about doing a similar sleeve for Suzukis. We could provide sleeves, pistons and machining instructions. Or I could convert your block. If there were sufficient interest, I would tear one of mine apart and start engineering the sleeves/pistons. I presently do stroker kits for Jeep 4.0l engines and spoke with my piston vendor about this. He said that If I do the engineering he can provide the parts. I was thinking about producing kits for G13 & G16 blocks, sleeve length corresponding with the deck heights. I haven't looked too close yet, but I' sure we could get 2mm or so extra bore. The Dartons for Hondas also provide a steel deck surface that substantially strengthens this area. I would likely do the same. I have 1.3's from an '87 Samurai, GTi, '96 Metro and a Sidekick 1.6 8v. I'm sure I can figure out a hot set-up for these. Anybody interested ? How much more bore would make it worthwhile? Give me a sign. "Build it, and they will come" isn't enough. I'll be investing a good bit of time & money to make these happen. Thanks for your input, MIKE

Mike,<br><br>This sounds great, the only think will be the head gasket since the biggest bore gasket is the one from the G16 and is only 76mm.<br><br>A good bore will be something like 78-80mm or more since 77mm is the max safe bore on G13 blocks.<br><br>Bolivar <p></p><i></i>

Bolivar,<br>thanks for the reply. There are some custom gasket folks out there. If I move forward on this, I'll probably get batches of gaskets to match. There are also custom-cut copper gaskets. The drawback being the need (sometimes) to o-ring to get a good seal. Either way the gasket thing is surmountable. I was kinda thinking 80mm'ish as well. Enjoy, Mike <p></p><i></i>

For cooper gasket you need to o-ring, I have one that I try to install and ended up installing a OEM one.<br><br>If you can make head gasket it will be excelent if they are metal ones that don't requiered o-ring. <br><br>Bolivar <p></p><i></i>

I am interested. I know LA Sleeve Co. (LASCO) make sleeves for the 1.3 and 1.6. But just to go back to standard bore apparently. I am checking into it. Please keep me informed. I would love to get more bore range on the 1.3 and 1.6. Cheap stroke is to offset machine the crank a 1/4 inch and move the wrist pin up. This in the 1.6 piston bore, get you about 1.5. In the G13b block. How much bigger are you thinking? How many mm in bore?<br>jbmcgalli@yahoo.com<br> <p></p><i></i>

moved to group purchases as this is too cool a post to let it disappear in the usual daily turnover ..<br>sounds like a great chance for gti owners & all the samurai guys who've made the swap, of course these aren't really expensive sports cars, so pricing will be a big factor in the kits success.<br> <p></p><i>Edited by: <A HREF=http://pub83.ezboard.com/bteamswift.showUserPublicProfile?gid=n1tr0>n1tr0</A> at: 8/4/03 11:24 pm<br></i>

I would be very interested to see if you could go out to 80mm .Looking at the g13b block there is approx 3mm steel liner and 7mm alloy jacket around the std 74mm bore.does this sleeve do away with the aluminium casting altogether or is it installed in the alloy?.I have just bored a block out to 76mm leaving approx 2mm steel wall thickness,as this is going to be a high boost drag engine I am a bit concerned that the wall thickness may become a problem,so any more info/input on these liners would be appreaciated.<br> cheers dave <p></p><i></i>

On the Hondas we do, the aluminum cylinder casting is removed. The sleeves include a steel deck area and, locate in a step on the bottom. Thanks for the input, MIKE <p></p><i></i>

The sleeves are "wet". They are in direct contact with the coolant. This works for many other engines that are designed that way. MIKE <p></p><i></i>

Darton calls it "modular integrated deck".<br>The sleeve locates in a "step" machined in the bottom of the block and the steel deck locates in a step machined in the top. The sleeves also interlock with each other. Look at this link: <!--EZCODE AUTOLINK START--><a href="http://www.dartonsleeves.com/mid.htm">www.dartonsleeves.com/mid.htm</a><!--EZCODE AUTOLINK END--> for an idea of how they work. I was going to do the legwork to make a similar product for Zuk's. <p></p><i></i>

that's sweet looking alright.. have you taken a good look @ our blocks to see if they're a real possibility. i'll probably need a better job before i can afford a rebuild like that, but it's still sweet. <p></p><i></i>

AccurateMike, What size bore are you hoping to get to. On the 1.3 and 1.6 block. minimum and maxium. Plus any kind of cost guess. Just to get an idea. For the sleeves alone. Also are you looking at a hardened steel sleeve. Or just a mild steel or cast iron. Also can we get them setup already for o-rings. Also you or someone may need to look at some sort of upper cyl. bracing. The Honda people call them block protectors. Basicly connects the block to the cyl. Making it like a full deck top surface. This would be for the 1.3.. Well just for the people that may want to go for it all in boost. <p></p><i></i>

The sleeves incorporate the deck plate. See the link above. Bore would be limited by combustion chamber diameter at some point. Several mm's overstock is possible. Thanks, MIKE <p></p><i></i>

Drop me an e-mail when you get some more details. Price and max bore. Also if we will be able to get them pre o-ringed.<br>jbmcgalli@yahoo.com<br> <p></p><i></i>

to get them pre O ringed you will need to know the ring land width on the gasket and as these will have to be made to suit the bore sizes that is not very practical. <p></p><i></i>

Biggest problem is the g13b head doesnt flow more than a certain cfm and the vitara single cam 16v flows around 28cfm more straight out of the box for the g16`s 90mm stroke. Hence Suzuki Carbusters here in Melbourne are getting 196hp at 10,500rpm from a destroked g13b with custom scat crank and pistons to 1070cc, QT bodies, electromotive HPX and modded baleno or vitara SOHC 16v head. They swore that the g13b gti head can never flow what a SOCH baleno 16v head can. Hence their High output their speedway engine.
Why do you Zook lovers think g16 block and twin cam gti heads have been so disapointing???

Bore and stroke ratios are very important and so is cfm.

If its possible to get 81mm then factory hayabusa could probably be used.
Therefore making necessary savings?
