New engine parts

[victrolakid]

First off, I would like to thank everybody that has helped me up to this point, i really appreciate it. I would like to ask just a few more questions, my engine is out of my car and is going to go back in in a relatively short amount of time. It is at this time that I would like to ask everyone about what they think of the pertronix ignition kit, I would like to know if it is a worth wile part. Also I would like to know if there is any other small modifications that can be made to get the horses that i so desperately want. I already know that i am going with all standard parts, but if there is any little changes that anyone knows of and could let me know that would be great.
Thanks
Sterling

Definitely worth the money as it will save you time and money on points. It is more reliable and will give you better service.

I think most will second that. But be sure and read all the threads about Pertronix on this site as there is a lot.

Get rid of the slowwlex
Electronic ignition
dump the stock fan
change the tranny fluid to syn. and the rearend
cold air intake
Oh man this list could get long but its a start.
BTW to all the father's out there Happy Fathers Day !!!!

Everything stated previously, especially the Weber (as the alternative to the Slowwlex!), but a larger exhaust. At least 2" dia. from the point where it becomes one pipe. The stock exhaust manifold is okay to use (not ideal, but okay), but the stock exhaust from there on is going to limit the effect of your modifications.

port the intake..........easiest bang for the buck. IF you have a Weber. IMHO

Well thanks for the info. There are some really good ideas that i have been provided with, and i did take the advice that was given and get the pertronix ignition kit. I am going to change the carb to the weber but i have 2 one is a manual choke and the other is a eater choke and i am wondering which one go with. Also i noticed that it was said to change the stock fan, is that just the bladesor is that the whole thing, and what am i supposed to change the fan to. also I spoke with Gill over at Opel GT source and he said that having the automatic with the air conditioning, and only going with the weber 32-36 not the 38 dgas, that I wouldnt notice an improvment equal to the amount of money that it cost me to have the work done.

If you change to a Weber, go with a water choke. And yes 32/36 not a 38.

The reason people are saying replace the fan, is because the fan is directly driven off the water pump. This is fine for idling or very low speeds. However as the car is traveling faster, say 35-40mph, the fan is no longer needed and the fan is just robbing HP and sucking gas. The options are switching over to the 75 model water pump/fan and clutch or removing the fan from the early style pump and installing an electric fan.

With an auto tranny, it will be difficult getting great fuel milage. But any improvement is worth it in my book.

Don't forget to clean and repack the front wheel bearings with Redline CV-2 synthetic wheel bearing gease and use Redline synthetic in the rear end.

To repeat what Yellowopelgt stated above, the single best HP improvement bang for the buck... port the intake manifold per RallyBob's street porting article. This should be done when the Weber is installed.

The next thing I'd do, since you have the engine out and you are probably having the head worked on anyway... you are at least putting new, hardened exhaust seats in right? ... Buy some intake valves from an Opel 2.0 liter and install them in the place of the stock 1.9 intakes. Then have the machine shop blend the bowls and cut about 1/8" off the valve guide protrustion, but don't let them do any "porting".

Next install the Isky/OGTS Torquer cam shaft.

These mods should work well with the auto tranny buy adding low end torque and extending the power band of the engine significantly. These mods will really wake the engine up and with no loss of fuel milage.
