I'm falling behind again....

     I'm a little worried about going 10-10.5:1 c/r with the fuel thats availabile...I was kinda thinking around 9.5-10.0:1 as a max.
 
    Remember I llike to make these build rookies can copy.

     That said I like the idea of a 10.5:1, high revving 1.6/16v with one of the new style progressive cams I've been researching.

     In Oz and England is anyone doing any kind of racing with the Sidekick/Vitara, Rally, other?

Comp. ratio with the machined 78mm pistons is 10:1, not a lot more than the stock 9.5:1 but it helps especially with the larger bore.

I have seen photos of a swb Kick used in Offroad racing here but don't know anyy details as it's done in other States.

Zag, I know you're talking about doing a build that others can copy but no matter which way you go, stroker, big bore, turbo etc. there's bound to work that will need to shopped out and 10:1 comp ratio on these engines with their alloy head and decent gas shouldn't pose any real problems I would have thought. I mean if you're chasing real power gains and it means using premium fuels so be it. Even if you can't always get it you can always carry some octane booster with you to add to regular gas if need be. Just my thoughts.

I don't disagree CJ
     I guess I am just trying to get enough ideas together to come up with the most practical build and try to keep it real world and attainable.
     I hate the magazines that show these awesome engines...and then when you see the details it would take a years wages to build it.
     What do you guys think the average guy can really afford to spend to do a first class build?
Bearing in mind he/she is going to have to do the bulk of the dirty work.

Trying to balance power/practicality/attainability with a real budget.

Also bear in mind, I won't be starting this build for acouple months.

I can't really say on cost given where I am but I think it's going to be a matter of "bang for buck". I suppose it will need to be decided N/A or Forced Induction and that means making some assumptions on what figures can realistically be acheived with reliability ie. if we build a stroker engine how much would it cost for what power/torque improvement and the same for a big bore or a high compression stock bore and stroke or any combination of these and look at a Turbo or Supercharger build in the same light.  Will the forced induction use stock compression and a low boost setup or will some lower compressionn pistons be used meaning a tear down is required or what about using a decompression spacer and the turbo or blower used would need to able to found easily and cheaply enough by most users.

I have been thinking this is going to be the way to go,
I can get coper gaskets for a reasonable cost $100-150
if I remember right.

Might really solve your c/r problem....

     It's also interesting that it can let you play around with different types of pistons with out major machining...neat idea.

My handbook says CR is 8.9:1. Ignition Timing 8deg vor p.m.s. (Spanish eh, they forgot to translate that bit, lol) 91 Octane RON or higher. Our lowest grade fuel is 95 octane RON so I reckon theres scope for 10:1 no problems, maybe back the timing off a little bit if it pinks. I don't think I'd want to go over that on a 2V per cylinder motor for the street, I don't have any numbers to back that up it just seems to have traditionally been the limit for a street motor over here since they dropped 100 octane fuel years ago.

I know of one that has competed in the last few years in Safari racing (I would imagine its a bit like what you were /are planning), won its class too. Mainly we do low speed trials type driving, the sort where the spectators walk faster than you can drive  Most sites have a 5mph or 10mph speed limit which is usually pretty optimistic.

My fuel concern is here posted octanes are

-87 Regular
-92-95 Premium

My Alfa is 11.0:1 and I have to blend avgas and premium to keep factory settings and that is a pain.

Rhino the 8.9:1 is for the 8v and we are talking about the 16v which is 9.5:1

Zag, we have 98 RON which is about your 93 and that should be fine for a 10:1 but yeah I wouldn't want to try 11.0:1 on it.

Yeah but CJ

     Premium just went to 1.099 a litre, and I'm cheap! lol

oops  Not concentrating again. The figures for the 16V were right in the next column too 

So the interest level is for the 1.6/16v?

     CJ and Rhinoman, you guys would like to see the build kicked up a notch from your comments.
     Whats everyone else think?

Personally I'm waiting for the 2ltr conversion. I'm interested in how the others go because I'm always interested in that kind of stuff. I don't think it would be worth my while fitting a 1.6 16V to my 8V but the 2ltr would be worth it and the old 1.6 8V could always go in either the Jimny (using the Jimny top end and MPI) or the 410. At the moment my insurance is a killer because of some naughtiness on the bike, but it will come down a bit next year or the year after.

Ah my 1/2 built 2.0L swap

     That along with other projects is on hold due to business problems, but you and my wife are waiting for it. Shes not as patient, she wants that 135hp in a big way!
     I will keep you posted when I get back to it.

Yep, I looked at doing a 2.0 swap but right now a worked over 1.6 16v is of more interest as it's no drama doing some tweaking to the original engine but a swap is more involved down here as we need to deal with Engineers Approvals on these sort of mods plus it won't alter the insurance. Also there's probably a lot more 1.6's running around that guys would like to get some more power out off. The 2.0 will start to be more popular as the prices drop and availability improves. But I have been toying with the idea of buying a 2.0 swb as we had this model
