I got the spacer off ebay for around $40. The seller's name was Kevin Harris...I'll send him an email to see if he can still get them. I won't be able to tell you what the performance difference is because I am installing it with the new engine.

I have a cold air intake for it as well...so with the Calmini cam, ported/polished head, Calmini header/exhaust and the fresh rebuild I'm hoping to feel a bit of a difference over stock ;)

Did it come with longer TB bolts?  I'm thinking there may be 1/2" available on the stock bolts, but probably not much more.

I was not able to find longer bolts at the local hardware stores.

I didn't look for threaded rod.  That would be a nice solution I think 'cause it'd be like having studs.  But, getting metric bolts/nuts/threaded rod/or anything metric in the states seems to be kind of tough.

I just got an email back from Kevin, he is expecting some in 'soon'. So anyone interested keep an eye out for them on ebay. Hopefully he'll send me an update when he gets them so I can let you know.

doesn't a spacer give more horsepower, but less torque, where a shorter intake does the opposite??

The length of the intake runner
changes the ram force of the intake
charge, think of it like stopping the
flow of water in a long pipe, and then
stopping the flow in a short one

Shorter I think is better for higher RPM
Horse Power, and longer is better for
lower RPM torque

Yep Wild has it right, it is designed to increase torque.

Theoretically, I'd like to see some one dyno test one on a Track/Kick. I played with manifold lengths on my old race bike. The shorter the manifold the more power I got everywhere. I spent ages making the longer manifold too!

There are other factors involved too,
size of intake runners, port and valve
sizes, shape of the port floor and even
the shape of the combustion chamber.

shorter intakes seem to be better on
high RPM engines, the ram affect has
lots to do with the speed of the intake
charge too, a speed of 220-300 feet
per second seems to work well, and
will increase power over a slower speed
intake charge, even at the same RPM and
Cam ect.

Ok well then a shorter intake would be better for the 1.3, since it is a higher rpm motor?

Higher RPM being defined as
6000-15000 RPM   :o

I don't think the Sammie is ready
for that yet  ;)

Hey Wild now that you've mentioned cams, I compared my Calmini to a stock cam last night. The Calmini has less lift but a more asymetric profile. The lead side of the lobe is almost flat, the trail side has a egg like curve to it. The stock cam is almost symetrical but definitely ramps faster on the lead side. Another oddity on the Calmini cam is the distributor end. The large flange is probably 1/4" closer to the front of the cam than it is on the stocker, even though both cams are the same length. We slipped the Calmini into the new head and it has about .035'' clearance to the back of the distributor housing.

I'm sure pumped about getting this engine together :)

can you use a dial gauge and degree disc once its installed and give us some numbers?

The guy that's building the engine is going to do just that...I just have to remember to relay that info here ;)

This is a real learning experience for me, he's letting me get my hands into all of the prep and he's explaining everything that we're doing and why....its kind of funny actually, we have my little 1.6 on one bench, then on another he's building an Olds 455...I'm pretty sure I could stuff the 1.6 block down one of the 455 bores  ;D
