1600 Rebuild - Stock or Modified?
My father and I (mathcg) are rebuilding his 67' Giulia GTV. The car is currently at the bodyshop, however within a few weeks we should be receiving the engine (which we were unable to pull since we do not own an engine lift). For those unaware, it is our intention to rebuild the car ourselves (with the exception of the body / chassis work). Our next step will be to rebuild the engine. My main question here stems from a conversation I had with my father. I thought it would be better to do a "stock" rebuild, whereas he leaned towards adding some performance while we were rebuilding it anyways.
- For those that have driven both stock and modified 1600 engines, which would you prefer for a weekend street driven car?
Some backstory for why I'm asking. I feel that the engine really determines the "feel" of the car to a large part. I used to own a modified 91' 300ZX Twin-Turbo. The car was seriously fast, probably ranging from 400-500 bhp on high-boost. However, for me it was too much. The power was rarely usable on the street and mostly went to waste. I could use a very small percentage of it's available power. The un-reliability that ensued from owning a modified turbo car was also too much for me to afford. My current car is a stock 83' RX-7. The car has a meager 100 bhp, but I find it much more enjoyable to drive. For the most part I can use 100% of it's power in a legal, safe way while driving on the street. For me this is much more fulfilling. I don't want my father's car to have a peaky race engine that can hardly be enjoyed or used to it's full potential on the street.
So for those that have driven both, which would you prefer? There's probably no "right" answer here, but since neither my father nor I have ever driven the car, we don't have much to go by. I'm of the opinion that the car is probably a real joy to drive in stock form, but again I have nothing to really go by. If we did decide to modify it, my idea would be to do a free-flowing exhaust (we probably plan on doing this anyways), upping the compression a bit and putting a mild cam in the engine. Nothing crazy. My father is not wanting to do anything crazy either.
- We're set on keeping the stock 1600 engine, and aren't interested in swapping to a 1750 or 2000 engine. Originality is important to both my father and myself. We also own two 1600 engines anyways.
- Neither my father nor I have ever taken apart an engine and rebuilt it. We're intentionally trying to do this ourselves (that's part of the point of this car), so please don't suggest we pay someone to do it for us. I can't imagine we won't be able to figure it out, at least with a bit of help.
As an addendum: if we do decide to go the stock route, what can be reused, or would people recommend reusing? Should we be able to reuse the rods and pistons? Either way should we have a machine shop balance everything?
Thanks in advance!
