Rick I agree. For road use the standard exhaust manifold on an L16 isn't too bad, and its a lot quieter thasn extractors. Its not going to restrict breathing as much as what follows it. The puny stock exhaust system should be simply up graded to a 2 inch one. The other big restriction is the intake breathing. Buy a pair of twin SU's including the aircleaner, linkages and manifold from a 180BSSS for about $100-$150 and you will get another real improvement. That's about $400 all up, but both mods will be able to bolt on to your new L18 engine (with a good breathing head and cam) when it comes.
If all this seems too expensive how about going back to basics. Is your current engine in tune? Good plugs, and particularly points with the right settings? Distributor advancing correctly? Clean airfilter? Valve tappets set correctly? Cam chain not stretched to the point where cam timing is badly retarded? These all reduce the performance and carbs and exhausts wont help if these basics are crook. ----- Original Message ----- From: "Rick White" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, 8 July 2002 0:47 AM Subject: Re: extractors for l16 > James. > Here is what I know about extractors and the pro's and con's of them. > My mate has sspent years building race engines (honda ones unfortunatly) > And this is what he told me. > Extractors can give you either more responsive engine - More revvie > Or they can give you more torque - loosing your responsiveness. > (great for towing though) > I took some I bought of some one a while ago and he measured them up and he was sure they would actually rob my 1600 wagon of responsiveness as they were designed for torque. > Hense the reason they are not on the car or will ever be on it. > He also has had a little experiance with Datto's and he was quite adament that on a stock L series the factory manifold with a decent 2 inch system would be quite a good thing. > As my wagon is stock I won't be bolting any extractors on my wagon until she needs a rebuild. > Then I will be doing a bit of headwork to her with a nice cam and some heavy duty springs. > I also have a genuine 1971 1600SSS 4 door and the factory extractors are totally different in design to the ones I bought for my wagon. > So I guess I will be taking the SSS in with me when the wagons engine is rebuilt so they can copy Mr Datsuns extractor design. > Maybee Terry or Errol can elaborate more on the pro's and cons of extractors but I wouldn't be rushing out to buy the first pair I found as they might not be such a good thing. > Any how take it easy. > P.S Take your car in to a retuable tuner you will be amased what a little tuning can do for performance. > I know as I have spent months tinkering with my wagon and on a cold morning WOW I LOVE IT!! > Later. > Rick White. > > --- "Chris Simpson" <[EMAIL PROTECTED]> wrote: > > > >Well yes they are a bolt on, to the head that is, but you'll then have to > >go down to your local exhaust shop to get them to weld the extractors to > >the current exhaust you have.
