davidh Posted November 19, 2003 Author Share Posted November 19, 2003 what would be the most hp you can get with a well tuned carb on the street, you know daily driven and and with the best gas milage? Quote Link to comment Share on other sites More sharing options...
Guest Nic-Rebel450CA Posted November 19, 2003 Share Posted November 19, 2003 What engine do you have in your Z? How much HP do you want? There really isnt a limit just because it is a carb, it just depends on how you build everything. Gas mileage is more a factor of what engine you have than anything else. If you can tune a carb then this wont be an issue. Try searching and browsing the forums, you might be suprised by how much info you can find...

brokebolt Posted November 27, 2003 Share Posted November 27, 2003 I'll toss in my opinion. Yes engine dynamics does play a big roll in engine performance and fuel economy. If your looking for an easy to tune and reliable set up that provideds good fuel economy and reliable performance I always tell people to start with an early set of SU's (bell tops not the bucket tops). These carbs are relatively inexpensive, provide resonable power and good fuel economy. They still have parts readabily available so parts hunting for nozzles and needles isn't an issue. If your more leaning towards performance than a well tunes 4bbl is aslo good. Parts are cheap and avalibility is good. If your looking for maximum HP than tripple carbs are better. There is also the twin downdraft as an option and larger SU's can be adapted from a Jag. Price is also a factor as the performance level goes up so does the price tag. Fuel usage on the SU's was around 19 MPG on a 3.1L with headers and 298 duration cam 44mm intake valve 35 exh. BUT if you opened it up and drove like a owned stock in a large refinery than it went down to about 12 MPG The other inducitons I never drove them conservitely enough or used them as a daily driver long enough to get good MPG numbers, but with wide open throttle it was low like 7MPG.

Guest bastaad525 Posted November 28, 2003 Share Posted November 28, 2003 If you have the Nissan straight six go and are going to be driving on the street go with SU's. If you're gonna be racing on the track, and not driving on the street much if at all, and want good power at high revs, go with triple carbs. SU's are the best all around carbs for the straight 6, and are incredibly easy to tune and maintain and even rebuild. Quote Link to comment Share on other sites More sharing options...
