I know there is a general consensus on Bilsteins for the suspension. Is there a similar consensus for exhaust? I have a stock 1972 1.7 FI. Now I have a monza four tip exhaust of unknown quality (it seems too loud) with three of the four chrome tips cut off (from PO). I am pre-smog and use the car as a weekend driver (and hopefully an autoX or two per year).

You should install this exaust!
(from the 914 1.7l turbo thread) (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif) http://wwwhttp://www.914world.com/bbs2/ind...=ST&f=2&t=17090 Attached image(s)

I am attempting to copy this design for my 1.7 Just finished doing a side shifter swap on the transaxle. Once the Mega Squirt unit is installed and tuned, I get to start the fun!!!

What about the compression of the non-73 1.7 engines? I was all convinced that I wanted to do the same thing to my 1.7 until someone pointed out that unless its a 73 1.7 it has higher compression ratio. Is this really critical? Otherwise I was planning on turboing my 75 1.8 engine which has low compression..

it all depends on the amount of boost. if its wild lower compression might be good (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif) really simple exhaust design, i want to try a type4 turbo some day |

8.2/1 CR is not THAT high. It's like jd74914 was saying, as long as you keep the boost down, it's not that critical. I will only be looking for 8-10psi boost. The other thing is that I will be running Mega Squirt. The brain will take an input from a knock sensor...MUHAHAHAHA (IMG:http://www.914world.com/bbs2/html/emoticons/burnout.gif) |
