(IMG:style_emoticons/default/biggrin.gif) Hello all!
Welcome to the "NANDO BUILD"! From this first page onward the saga of one mans quest for Uber reliable power will unfold.. My good friend Nando (martinef1963 - club member here) has experienced engine power problems. He has made the decision to rebuild for two primary purposes: 1 - Must be stone reliable and all things working (heat) 2 - Must make more power than stock. I went down to his house which is about 45 minutes away and helped him pull the engine. We then loaded the engine is his beast and brought it back to my skunk works: "Exhaustive Solutions". And thus began the teardown - But let me back up for a moment. Nando was unsure of just where to go with his motor. Size wise, power wise, money wise, etc, etc. So I took him for a ride in Black Sabbath - Here is what comprises my motor build: 1.7 liters Original 1971 90mm pistons and cylinders (almost worn out, I just did not have the money for upgrade when building, which is what many of you, are in the same predicament) These have a fair amount of blowby, and are probably affecting my overall compression ratio by -2 points by guessing..so prolly around 7.1:1 at least. A SCAT C20 cam - Weber 40mm IDF's with stock vents, 120 mains and 45 idles with F7 tubes. Short manifolds 2 liter headpipes with monza manta exhaust 009 with crane optical Now I am the first to admit, my motor is not "new", nor is it at full power levels had I had the money to do it the way I wanted.... I'll just let Nando tell you all what HE thought----- Back to the motor: This is one reason why low power---- These are the really small valve 1.8/2.0 heads. W/o cleaning thay look to be pretty good, will know more when cleaned --- I have some bolt-on power mods I have been working on for quite some time now, and a few will be incorporated into Nando's engine. I am using Black Sabbath as my on-road test bed. Everything I do is backed up by road tests and chassis dyno tests.......Stay tuned for info and pics. (IMG:style_emoticons/default/cool_shades.gif) |

1st would like thank JWalters for his help and savy on this project.
I did give him a brief history, or what I know of the engine. It is a California engine that my old mechanic (Domonic - on the board) procured for me back in 1997-1998. I drove the car from Vacaville CA to Atlanta and it stayed there for a year while I was off doing some contract work in BumFuckiStan (one of the Stans). I had some body work done on it, paint etc., but really just kept up w/ the oil changes, tune-ups, etc (nothing major). Bout two months ago it started to smoke real bad and died one day- later to find out that a plug or two were soaking in some oil. And here begins the Nando Build. I will also be doing some rust work in the hell hole - not bad. I will be posting some pictures today and of progress. Could kick myself in the arse for not taking some pictures of the before, but none the less the top side of the engine was a very basic 1.7 FI set up. Getting back to the ride I took/drove in Black Sabbath - WOW! The ride was unbelievable - I thought my car had it going on (NOT). The car had plenty of power w/ awsome response and it cornered incredibly! I can't wait to get my girl on the road. I will be posting some pictures of the work that I will be doing to her while the engine is pulled. Hood, and engine compartment. I did get a good mix of responses on my Powder Coat/Ceramic question/concerns and have decided to leave the SS alone (polish them), powder coat all of the heat related tin, engine compartment tin, and some other items. mz |
