Here are a few comments, and questions. Your 16v project only gives 16 lbs more torque, and the same hp at a lower rpm. 

I'd be interested in how flat the torque curve is too. 16lbs more peak torque might not sound a lot but if it is a flat torque curve then it can be a much bigger improvement elsewhere. Years ago one of the car mags over here used to take an integral of the area under the power curve to give a better representation of how much overall power an engine made, it is a useful comparison.  I ended up doing this with my bike engine too to get an accurate idea of the total power made in the usable rpm range. For the race bike (600cc single cylinder 4 stroke 5 speed road gearbox) the useful power range was 5000-8500rpm in the dry 4000-8500 in the wet. One time I made a cam change and I got 10% more power, lap times at my local circuit were the same. Taking an integral over the 3000rpm range used showed the bike made the same total power - it was just peakier and more difficult to ride. I hope this makes sense cos I've had a few drinks  ;D

hey Zaggy on the subject of engine mods, you said you read a lot of stuff down the library. Have you got any good recomendations for books or white papers. The only stuff I have is bike stuff (4 stroke) a lot of which still applies but i was looking to read up on some more car focused stuff. I have at least one engine to rebuild (1500 Ford - not Zuk I'm afraid).

Peak power figures don't really tell the whole story. I agree the torque curve has to be looked at. We need to remember that Power is Torque x RPM so if you have more torque created anywhere in the rev range you have more power at those revs and more power means we can go faster. A nice big flat torque curve would be great even if the peak power barely changes. Zag I know in some of testing you have done you have used standing start acceleration times to measure gains but may I suggest that you also consider doing some "in gear acceleration times" in different gears as this will give a good indication of the driving characteristics to be had.

Hi gang

CJ and Rhinoman
     You are absolutely right when it comes to torque...the more the flatter the better. Interesting Ideal on the area under the power curve, I like it and it makes sense.

Rhinoman
     Playing with Fords eh. Must be for that limited production sports car I saw on your website.
I'm at the shop right now finishing some stuff up but remind me and I will see if I have any good references.
     1500 Ford, that would be the Kent engine, 1100, 1300, 1500 and of course the 1600.
Anglia, Cortina, Escort and the infamous formula fords and Lotus 7 series 1 through 3... Super little engine. I'd suggest check out the guys racing sedans and Formula Fords....these guys have forgotten more about those motors than I will ever know.
     You live in the land that did all the performance and developement work on these engines. I'll bet parts will be cheap and easy to get.
     Jim Russel had some good prep books on these. Also most 65-70 Cortina GT parts should swap......cool project I'll check my stuff too.

You lose that bet, lol. Stuff for these old motors costs a lot as the historic racing boys want it all. Its a 1500cc 120E engine, the early pre-crossflow engine that later evolved into the crossflow.

Holy Smokes

     That one is older than I thought! As far as good basic books..........
- Smokey Yunicks power secrets is one of my favorites, covers the basics on most topics.
- Preparing to win, last name Smith, is also a good basic book.
- Of course the manual for any given engine is always a must.
- Basic engine design by Paul Lamar

The books I get out of the library are genrally reference books....
- Sound waves and Sonic waves
- Mathmatics of Automotive engineering....SAE manual
- Hydralic flow and design...SAE manual
- Aerodynamics...SAE manual

I might have some of the titles screw3d up as I end up looking them up by topic but this should help.

You might also want to check out....
- Building the Nissan A-12....Nissan motor sports
- Race prepraing the Datsun 1200/B210/210

The engine is of a very similar design and a lot of the information should transfer. (it's rumored to be a rip off of the english engine)

Hope that helps

About 15 years ago, A friend of mine in Montana had a sammy.  He towed in behind his motorhome.  Once he went to Yellowstone.  He camped at one end and drove the sammy to the other end.  His fuel pump went out, so he hooked up the window washer to the fuel line.  He had to keep squirting it all the way back.  What does this have to do with this thread?  He always wanted to put a B210 engine in.  He finally did, but he moved before I got  to see it.  He was in the Air Force.  I had a B210 for 9years.  I thought it was not that much of a power boost.  But 60hp to 80hp is a 30% increase, so I guess thats not too bad.

You friend is amazing.........

     I never would have thought of using the W/S washer for a fuel pump...that is cool. The old B210/210 A series was a good old girl and are still being actively raced.

Thanks Echo

Project RallyKick is back in action

     So I am quietly starting to gather parts for this project.......it will become the 2nd engine for project RallyKick!

The fellow the ended up with the "Do it yerself engine" was just by for coffee

After a couple trips up North it's all broke in and on it's second oil change.

-Perforance as per last reports
-Gas mileage up to 37mpg Cdn, about 31-32 US
-Loves the engine
-Hates the Pacesetter header, had to have it repaired twice, switching to a Calmini next time
 it fails (be interesting to hear the difference)
-Adding a full low restriction aircleaner set up instead of just the K&N insert

All in all a happy camper

With all the new members I thought I would bump this up as it should answer alot of the questions that have been coming up.

Hope it helps

I am new to modifying engines but would it be a possible mod for the 1.3ltr sierra/samuri and remain reliable. Use the 1.6ltr Crank with the 1.3ltr rods and higher crowned pistons (possably Domed topped pistons) also to use the Swift GTi head. so you arrive at a stroker 1.3 that will have higher compression with twin cams? What are your thoughts? I currently have extractors with 2 1/4' exhaust and a k&N hi flo pod

never use oven cleaner that contains LYE , it distroys aluminum
old fashon EasyOFF has  pure LYE.

it is the best grease cutter,  that is true.

ware goggles , cuz it remove Eyes too.
