TTONEFOURTWO Posted September 23, 2012 Share Posted September 23, 2012 Hi guys. I recently picked up an S14 F/L SR20de motor off a friend for my corona. I've had a change of heart over the Ca18det turbo setup that I've almost completed and decided to run it NA. I've read about people using Minuki 44 side drafts and an MSD ignition. Has anyone on here done or know much about putting side drafts on an SR20de and could give some advise? I've seen similar setups like this one on speedhunters: http://www.speedhunters.com/2012/06/carbed-s15/ No spam please. Thanks. Quote Link to comment Share on other sites More sharing options...
Taistorm Posted September 23, 2012 Share Posted September 23, 2012 Give Murray at Weber Specialties a call, he'll be able to point you in the right direction. Quote Link to comment Share on other sites More sharing options...
keltik Posted September 23, 2012 Share Posted September 23, 2012 I slammed a weber on my EJ20. Was surprised how well it worked. Only word of advice from me is if you do use a downdraught carb for some reason - dont forget to orient the float bowl the right way round. Weber specs guy is a champ so +1 for him.

TTONEFOURTWO Posted September 23, 2012 Author Share Posted September 23, 2012 Thanks guys will give him a call. If I do then it will definitely be side drafts. Its weird that theres not a lot of info out there about this, just found of pics of S13's with the side draft conversion... I guess it would be unique in NZ?

Gaz Posted September 23, 2012 Share Posted September 23, 2012 Wouldn't you be better off to run ITBs. Whats the point of going to carbs, to make wiring easy? so you can tune it yourself? Gaz Quote Link to comment Share on other sites More sharing options...
TTONEFOURTWO Posted September 23, 2012 Author Share Posted September 23, 2012 In theory ITB's would be the way to go, just been seeing a few drift cars in japan with carbs got me thinking. It looks so clean and is really raw sounding. Will also be easier with less wiring/expensive ecu tuning. Just really wanted to know if anyone in NZ has done this before and if its a dumb idea or not. Its just something different... Quote Link to comment Share on other sites More sharing options...
nzstato Posted September 23, 2012 Share Posted September 23, 2012 When it comes to multiple webers... it is NEVER a dumb idea... Quote Link to comment Share on other sites More sharing options...
HighLUX Posted September 23, 2012 Share Posted September 23, 2012 Bike carbs? Use a megajolt or similar for ignition Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted September 24, 2012 Share Posted September 24, 2012 bike carbs are a very cheap way into 40mm side draughts. and personally i would love to see that. it should make some decent numbers with that setup. and manifolds are very very easy to make.

TTONEFOURTWO Posted September 24, 2012 Author Share Posted September 24, 2012 What kind of bike carbs would you recommend? Are 40mm big enough for the motor? I was thinking about the manifold, would the easiest way to do it be to get the flanges cut out of alloy and then use tube to make the runners? Or make it out of steel?

This.There are a couple of threads on the forum for converting to bike carbs that go through what you need. Sounds like you have the right idea though. Biggest issue will be getting spark because you'll probably have to ditch the ecu, as it won't be seeing all the necessary inputs without the intake.

TTONEFOURTWO Posted September 24, 2012 Author Share Posted September 24, 2012 Just been reading up about Yamaha R1 carbs and they seem like the go. Seem fairly cheap to buy/tune (buy jets etc). And manifold for them shouldn't be to hard to make. Will definitely be ditching the ecu. Would something like this MSD unit be tunable enough to run on the factory distributor? http://www.trademe.co.nz/motors/car-par ... 116060.htm Thanks for all the help!

R3spct Posted September 24, 2012 Share Posted September 24, 2012 You would need a distributor setup to activate it by the looks of the diagram. Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted September 25, 2012 Share Posted September 25, 2012 R1 carbs would be my flavor of choice (they will end up on my car one day too) and i also inteded on either getting a flange cut and welding a small bit of pipe for each intake and then hosing it up, or even cutting a factory manifold in half and hosing the carbs up to the stock flange. i dont see any issue with this if you do it smooth and tidily.
