easy - get a big gas cylinder - bolt it down, fill it with enough helium so as it doesnt turn to liquid, and
it makes it lighter....
easy.
Im going out now to port my ashtray and shave the dashboard.


Linc.

There once was a drunken Sparky called Linc,
Who enjoyed telling his mates 'I can think',
But a WD40 mental block,
Caused his head some serious vapour lock,
And he found himself feeling quite, ummmm..., stink.

Andy, I installed a NAPS Z-20 into my first 1200. It went in nicely and fit well. I had to move the radiator forward and build transmission and engine mounts but other than that it
wasn't too hard. I've been told that the KA is up to 1.5 inces longer than the NAPS Z so that might cause some problems. The KA makes a lot more torque but won't rev as high as a smaller
engine. As a side bar, have you made the move to San Antonio yet? Tim

I put a NapsZ engine into my old 1971 pickup. I took out the worn out L20 engine that was in it. It did not run as quick. Other than getting a motor that didn't burn oil, I
would much rather have the L20 motor. I thought the twin plugs and all would have been better but they just weren't. I was dissappointed. I sold the truck, a big mistake also.

I never used a hole saw on that car. Photos would probably show things more clearly. The front crossmember was removed and the bottom pick ups boxed into the chassis rails. Bottom suspension
arms were chrome moly tube. Struts were Ford Escort with integral steering arms and single bottom mount. The steering was replaced with an alloy Fiat 124 rack. The inner guards and front
panel were removed from the strut towers forward. The radiator was an alloy & plastic one out of a Mercedes 190. The steering column had it's housing removed. At the back the floor between
the chassis rails was removed and the crossmember behind the seats was replaced with a lighter tube one. The rear shocks picked up on the rollcage cross brace. All the steel panels were
attacked with a plasma cutter and only the skins remained. The window frame on the doors were chopped off and the exterior door handles shaved. The body structure inside the window pillars
can be removed it is often 3 layers and the cage can be snuggly fitted into the gaps in such a way it isn't clearly visable. The cars construction was a major exercise and I was pretty cut up
when it was destroyed though I was thankful that my good mate driving it was ok after regaining conciousness. There are plenty of other things that can be done to get a car light and that car
was an exercise to see just how light we could go without it falling apart. Progress on my new car was slowed yesterday when 2 low lifes visited my workshop attempting to buy one of my cars.
While I was out the back they grabbed a box of brand new parts for my car including a Tilton pedalbox, master cylinders, Willwood calipers etc. While leaving they also grabbed the adjustable
alloy strut tops and strut brace I had made. The brakes and stuff are easily replaced but it will take me hours to make the new stuff. The idiots even grabbed 4 of the stainless bottom arms
for the race car . All the stuff I made is useless to anyone as it was custom made to suit my car. If I catch the little bastards maybe I should try lightening them with the plasma
cutter!!!!!!

Thanks Stirling - would love to have checked out the engineering on that one.
Sorry to hear about the thefts - did these guys contact you by phone to answer an ad? If so get the phone record from Telecom - although I'm sure that's done already if the
police handling it are petrol heads!
Good luck.

No one call this man a dreamer cause i have had exactly the same idea, except putting one of these engines into a TINY suzuki 500? i think thats what theyre called, little 3 cyl things, very
very light. One important thing u have to take into account like someone else mentioned is that these engines are not built for torque low down, and thus internals can be lighter as they do
not experience as much stress. i would guess that an 1100cc motor would not hold up for very long pulling round a car weighing in the low 700kg mark. using the same gearbing would be a no
no! u would have to have a massive gearbox with ratios about 1000 rpm apart, in all about 20 gears just so that the bottom end holds together. An i dea that i often dream of is putting and
old renault F1 turbo V6 1.5L, one of the grenade qualifying engines with 1200hp in. very fun indeed.

Yeah I'm in San Antonio now, I've been here for 3 or 4 weeks now. On the drive down I cracked a piston somehow, so I have been patiently trying to get it fixed. I bought a brand new set of
pistons and am only waiting for my ARP rod bolts to come in the mail, they should've been here Thursday or Friday, but yet I wait. I must say that it is a PAIN in the butt trying to get
parts down here, either nobody stocks them or it takes 14 days to get here, I never had these problems up in Washington! Anyways, I am hoping to have it back up and running by the end of
this week IF I get the rod bolts by Monday. Anyways, talk to you later!

Hello Andy,where did you get the pistons from?

I've thought about this before.

I think the biggest problem you'll run into is getting the car moving from a stop. Modern 600cc motorcycles make up to 120hp, but not really enough torque to move a car
until maybe 7000rpm. A 150hp 1200cc motorcycle would be a better choice, but even then they don't make as much torque down low as a stock 1200 engine does.

It takes hp AND torque to make a car move. It sure would sound bitchin!!
