how bout a supercharger, i saw one at lordco the other day for an 8v, wondering how it works

Trev, u got anymore info on this? price etc.?? brand.....

i say a cheap blower motor, that would rock!

Stu

i vote for rotary swap or a supercharger with clutch setup like on the Mr2's and benz;s.... this way you can turn it on like A/C to save gas.

I say either a 1.6 8v turbocharged or supercharged.

Either that or a solid build up to hitting 100hp in a 1.6L 8v.

     Check out the "Do it yerself engine build" that got us up over 90hp with a fairly stock set up. With some minor tweaks it would get you to 100hp.

    I didn't think the DIY 1600 was much more than a well built stock motor with pretty minor tweaks...or are you reffering to the one that ended up in the aircraft?

Everyone else...

     Swaps and blowers (turbo and super) seem to be the hot topics....any other suggestions?
Maybe if the budget can take it combining the two...say a 2.0L long block build with a turbo into an 1600/8valve Side kick.....because of the expense that would be a long term project not a quick build ( Thin budget guys).

Last call for input.

how bout a 18:1 compressionengine?  at that compression, we could run straight diesel fuel, have amazing torque without the weight.  may need bigger flywheel and stronger starter, but I always wanted a super high compression engine

You could go 16:1 and run Methanol 

Not an outragous idea!

2.0L, Turbo'd on Methanol......gonna have to see what industrial grade metnaol is worth for 45 gallons. I wouldn't need gasline anti freeze after that.

where is your adventourous side?  surely the top end can take 18:1, and the bottom end could with a bit of work.  With the stock ignition and injection inplace, diesel fuel can be used and wont have any problem igniting it.  Think of the possibilities, a high speed diesel engine with all the torque and high rpm capabilities.  If I had a garage and a good engine, I'd do it right now. Actually, I may have to read up on the subject at what compression is ideal, but I'm guesssing it's between 15:1 and 18:1 without having to worry about preignition on diesel.  I know diesel tends to smoke with low compression engines, but there is a sweet spot, I just have to find it.

you may laugh at me now, but I'm sure people laughed the first time they heard propane injected diesel setup, and now it's the cat's meow

1.6ltr with 1.3 DOHC head. From the pics I've seen that head looks like the valves could be a bit shrouded - still makes 100bhp. Open up the combustion chambers a little and rephase the cam to give a bit more bottom end.

i say do a 16v motor. do some porting and polishing, maybe a custom cam grind. see what gains you can get from simple modifications. maybe see if it's possible to even reprogram the ecu to get some gains.

Zag,

I think a 1.6 16v with some work would be the way to go as most here will either have an 8v or 16v engine and you've covered some of the 8v but there is next to no knowledge out there on what works with a 16v. Keeping it to what most people have to play with will be more useful. Obviously a decision needs to be made whether it will be a N/A or force fed setup. The build could be as a N/A engine to start with and then go low pressure (5-7psi) turbo or blower later to show a progressive build without the need to tear the engine down to change pistons. You could use a decompression spacer if needed to lower the compression. It may be that you could look at something like a Megasquirt to complement the mods as needed. It would be great to see the effects of things like cylinder head work, intakes, exhaust mods, cams, cam gears, underdrive pulleys, crank scrapers, windage trays, knife edging the crank etc on a 16v engine being quantified in some way. Don't forget the option of resleeving and going to an 78mm bore. Yes, the 1.3 DOHC head could be used but my understanding is that it needs quite a bit of work to get any gains over the 1.6 SOHC head in N/A form althouh it may be better for a Turbo setup.

I vote for blown 1.6L 8v

I may have to read up on the subject at what compression is ideal, but I'm guesssing it's between 15:1 and 18:1 without having to worry about preignition on diesel.

Uhh try 24:1 for good diesel performance, these aluminum
heads can't take that much compression, as well as the shape
is wrong. Diesel heads need almost no CCs and are built as
flat as they can, the pistons are made of cast iron in heavy
diesel engines, I don't know what is being used in the smaller
engines, and the piston shape has a doughnut shape hollow
with a tit in the center, the fuel ignites in the hollow.

If you go lower compression, like 15:1 or even 18:1 you will
need glow plugs to get it started. In short, you need a custom
head  and then the block would probably not hold up.
