(Spesh with the reduced air flow because rear engine) If you can find the carb adapter from a C20 vannetre, that should fit. Then you can route a duct to somewhere cooler. Cold.air is free horsepower. For every eleven degrees farenheit that the temperature lowers you gain one percent power increase. Yeah totally correct. I'd even been into Nelson looking for alloy ducting but the place that stocks it didn't have the size I wanted. I'd bought a pod filter for the job but it was huge and ugly. I was going to mount it down low. I realise it's gonna be fucking hot up there so yeah.. I need to do something. However I just wanna drive the thing and check every thing out so a top mount filter will suffice for now. Ideally I'd be sticking side mounts in place given the huge amount of room I have there but again.. I just wanna drive it. Imps generate a big vacuum area and the engines get filthy quick (shame) . Certainly have to have a good filter system. The southern hemisphere cars actually ended up with a feed tube from the drivers door frame due to our dusty roads. But it's too tiny for a bigger engine so I removed it and welded over the hole. Id spotted the c20 top hat thing on datto wiki. Looks ideal. Easy to find?

yoeddynz Posted May 10, 2019 Author Share Posted May 10, 2019 This eh.... I could make one.. But later on Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted May 10, 2019 Share Posted May 10, 2019 Try datsun parts NZ datsun owners of new zealand, or new Zealand datsun club Inc on Facebook. Those three pages are the main go to. That an NZ datsun.com. I used to have one. But I gave it to @dirty_leppa. I don't know if he ever used it or not. (I also doubt he still has it either) Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted May 10, 2019 Author Share Posted May 10, 2019 I'm a member of the datsun FB group so yeah - I can try. But actually it'll be more fun and satisfying to make my own and then it can suit the spot perfectly. I have a feeling that the Datsun item will still be too tall. Must do sidedrafts..... 4 Quote Link to comment Share on other sites More sharing options...

Yowzer Posted May 12, 2019 Share Posted May 12, 2019 You mentioned it was previously supercharged? SC12s can be had for not a lot .. An air intake on the side like on an MR2 would allow for some super sweet induction noises Quote Link to comment Share on other sites More sharing options...
dmulally Posted May 13, 2019 Share Posted May 13, 2019 I have not only a C20 vanette, but an SC12 and a commer van carb hat. All can be had for rip off high prices. 2 Quote Link to comment Share on other sites More sharing options...

Its a sleeper. I don't want to give the game away that it has 68 ponies (gross..) waiting to be unleashed. 4 1 Quote Link to comment Share on other sites More sharing options...

Bluebear01 Posted May 19, 2019 Share Posted May 19, 2019 What an inspirational build, absolutely love your attention to detail with all the little things! Was the worry with the heater pipes to do with heater efficiency, or more to do with helping engine cooling? Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted May 19, 2019 Author Share Posted May 19, 2019 Hey thanks - glad you enjoyed the read Yeah it was more to do with making sure the cooling system works well. And it seems to so far but yet to take it up a good hill.... Quote Link to comment Share on other sites More sharing options...
h4nd Posted May 19, 2019 Share Posted May 19, 2019 I do seem to recall there's a good hill in your neighbourhood. I had a great time doing a thrash over it in Jan, even in the baby mover. 2 Quote Link to comment Share on other sites More sharing options...

azzurro Posted May 19, 2019 Share Posted May 19, 2019 great work man, as usual love the wee video, each time gaining a wee bit more speed and confidence. engine note is suitably angry, but in kind of a cute way, "ohhhh look at the cute widdle puppy trying to be tough and growly - whos a good boy? you are. yes you are" gggggrrrr 4 Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted May 19, 2019 Author Share Posted May 19, 2019 Cheers. Yeah it sounds meaner then 68bhp (gross...) should do. That little carb is certainly holding it back. At about 4500 it starts tailing off. I think also that the E15 electronic dizzy might not have the right advance, nor does the vacuum unit I've retrofitted from some ford. Basically I'm going to get a replacement main chip that's missing from the MS1 that I was given ages ago and at the very least run full lecky ignition. Injection won't be far away.. But for now.. Drive it. 4 Quote Link to comment Share on other sites More sharing options...
NickJ Posted May 20, 2019 Share Posted May 20, 2019 Forgive me for being too lazy to do the maths, but the contact area between the pipes is small compared to the surface exposed to the air/frame, i'd safely wager that any heat leak will be minimal compared to the cooling from such long runs. Imp looks pocket sized in some of the pictures, like it could be easily stored under a bench, the perfect car really! I wish you many pleasant adventures to come. Did they ever put SU carbs on the Datsun A series? 1 Quote Link to comment Share on other sites More sharing options...

yoeddynz Posted May 20, 2019 Author Share Posted May 20, 2019 yeah for sure those pipes were only just touching..but it was easy enough to squash them so every little helps I'm over carbs already... looking forward to injecting it. But for now I shall persevere... 1 Quote Link to comment Share on other sites More sharing options...
tortron Posted May 20, 2019 Share Posted May 20, 2019 Surprised you didn't spin up some phosbronze bearings for the throttle spindles I have done the o ring fix. But you could Barry out and tin the shaft and valve grinding paste lap it in to fit 3 Quote Link to comment Share on other sites More sharing options...
