Minesmith67 Posted May 7, 2015 Author Report Share Posted May 7, 2015 So what's the difference between the 36 and the 38 Quote Link to comment
datzenmike Posted May 7, 2015 Report Share Posted May 7, 2015 The 32/26 is a 32mm primary by 36mm secondary carb. It's known as a progressive carb with the secondary coming in as the primary opens above the 3/4? point. The The smaller primary gives good economy with the larger secondary for performance like passing on the highway. A good size for all 4 cylinder engines. The 38/38 is much larger and designed for larger displacement engines like 6s and small V8s. Both barrels open together so it drives best when 'stepped into' as the engine revs up. Slightly too large for most 4 cylinders and when gas economy isn't important. Quote Link to comment
84720FourWheel Posted May 7, 2015 Report Share Posted May 7, 2015 The 38/38 has 2 38mm barrels and IIRC is a synchronous carb. The 32/36 has one 32mm barrel and one 36mm barrel, and is a progressive carb. Synchronous=both barrels open at the same time Progressive=one barrel opens before the other. 2 Quote Link to comment
Minesmith67 Posted May 7, 2015 Author Report Share Posted May 7, 2015 Ok awesome I like progressive carbs anyway so I think I will go with the 36 Quote Link to comment
datzenmike Posted May 7, 2015 Report Share Posted May 7, 2015 Read carefully. The 32/36 is the progressive carb. Never over cam or over carb your engine. Better to have a smaller one and wish you had larger than to have the larger and wish it were the smaller one.

datzenmike Posted May 8, 2015 Report Share Posted May 8, 2015 http://www.turbodatsun.com/Z24%20Dyno%20Mule.htm This is GREAT stuff. All Z24 owners rave about the weber carb swap. The Hitachi is more for economy and emissions. Finally some dyno data. 1 Quote Link to comment
dogbolter Posted May 8, 2015 Report Share Posted May 8, 2015 Yeh the guys name is Ben he lives over east some place.... he's working on getting an inter-cooler working with it as well once he finalises everything (The turbo kit is complete) i'm gonna get one ... i have an engine in my shed which i am gonna build for trubo.. wiseco rods... stroked crank... scoop out some piston-top meat to lower compression.... Blow the turbo thru the 32/36 etc.. it's gonna fly ... however--- i'm not really interested in speed i just want more power in the bush and for pulling out stumps LOL... oh yeh look at this... https://www.calmini.com/detail.php?b=1&m=4&t=3&p=916&n= I went to look at a house a few months back and had to get into 1st low 4wheel drive to get up the dam drive-way... shit it was steep... the little z24 didn't like it much so i reckon with the turbo and the reduction gears it will climb trees ...

dogbolter Posted May 10, 2015 Report Share Posted May 10, 2015 Parts to get for the Turbo Engine Mod I'd be happy to answer any questions about the mods above .. a bit of a tip might be to think carefully about what you are going to add or change then plan it as carefully as you can and make sure you have all the parts on hand else you might create other problems that might not have been necessary had time been taken to think it though. During my own work i had to have my Ute running the next day as i use it for work everyday. The Old Girl Work Horse She works her ass off Her ass fell off Quote Link to comment
dogbolter Posted May 10, 2015 Report Share Posted May 10, 2015 I wish i had taken more pics during the rebuild .. but there you go everything is good in hind sight Quote Link to comment
dogbolter Posted May 10, 2015 Report Share Posted May 10, 2015 Oh yeh when you are fitting electrical stuff make sure you put fuses in every circuit as close to the battery as you can so that the fuse will blow before your wiring is damaged or worse still a fire breaks out. What i did was put in an extra fuse panel for the electrical stuff under the bonnet ... power that up after then get all your power of that then you have a fuse for every circuit. also make sure you have 100amp fuses between your aux battery and your battery controlled as well as between your battery controller and your main battery. With thermo Fans make sure you have each fan on its own relayed and fused circuit e.g run a given fan from a relay that has a fuse in line prior to the relay also watch that you plugs to the fan are good mine melted ... i did all my own wiring but had an auto-electrician put in a diode so the power from the fans would not feedback thru the various switched circuits ... e.g you need a circuit for the thermo switch, the manual switch, and the aircon switch to run all independent of each other because you need the fans for aircon, for temp control in isolation from aircon (when aircon is off) and for manual when both temp and aircon is off this is useful for 4x4ing also good if the thermo switch or relay fails as mine did on a few occasions.. remember you doing away with the mechanical cooling device.
