Toyparts Industries Posted July 11, 2007 Report Share Posted July 11, 2007 hey all... onto yet another good idea for ae71... 4age carb'd... idea was to have a gze bottom end for strength and reliability and then 20v head with quad motorbike carbs and trumpets... havent done much research into it so any information or opinions on the idea would be great... :) Quote Link to comment Share on other sites More sharing options...
NoPsi Posted July 11, 2007 Report Share Posted July 11, 2007 They go well with carbs. I had a std 16v 4ag with twin webers and bluebird serIII dizzy. It went harder than a std 4ag with injection. Quote Link to comment Share on other sites More sharing options...
Toyparts Industries Posted July 11, 2007 Author Report Share Posted July 11, 2007 thanks mate keen for any info i can get my hands on... relatively new to performance engine with carbs idea... not looking for outright hp just clean responsive engine i can thrash all day and has that wicked inductions noise every enthusiast loves to here Quote Link to comment Share on other sites More sharing options...
andro0o Posted July 11, 2007 Report Share Posted July 11, 2007 carby 4age's are the gayness, have fun retuning ur car every cold morning, my mate built one and converted it back to efi in 3 days, its abit of a mission to build the thing anyways, you need to plug up the injector holes and a whole mess of other shit, its not worth it and you'll get over it VERY quickly. though i must admit, they sound AWESOME!!!!!

NoPsi Posted July 11, 2007 Report Share Posted July 11, 2007 Sounds like your mate's setup wasn't sorted right. I had no such problems. Quote Link to comment Share on other sites More sharing options...
Redwarf Posted July 11, 2007 Report Share Posted July 11, 2007 (edited) Concur. My sister had carbs on her 35 and it was a good thing. Carbs are not something you put on and expect to work. A dyno trip is a must, and after that you shouldn't ever have to touch them again. Don't root around with bike carbs. Other people have tried, and if they were a good thing, everybody would be using them. Get a good pair of carbs (Webers or Dellortos, try and stay away from Solexs), a manifold, bolt them on and off you go to the dyno man.

Toyparts Industries Posted July 12, 2007 Author Report Share Posted July 12, 2007 cheers for all the input... sounds like everyone has their own opinions... seems most are more into the twin webers/delortos tho... I'm all good with that as long as they are good for the hp i wanna try and run... like say 150 hp atw... I'm gonna build the motor high comp everything aiming for maybe 11-11.5:1 and race head like O/S valves race valve springs good port and polish big cams probably 288...

Sam_Q Posted July 13, 2007 Report Share Posted July 13, 2007 a 4agze bottom end wont be more reliable unless you have forced induction Quote Link to comment Share on other sites More sharing options...
Toyparts Industries Posted July 13, 2007 Author Report Share Posted July 13, 2007 yeah have come to that conclusion have decided to just use a small port engine rebuild high compression like 11.5:1... the paradise racing head... and strap on some twin webers probably 40mm or a bit bigger depending on what size i will need to run 150hp atw...

Redwarf Posted July 13, 2007 Report Share Posted July 13, 2007 150 Hp ATW in an NA will be an ugly thing to drive. 11.5 to 1 and your looking at the top end of what pump fuel can do for you. 40mm Webers maybe a bit small, I'd suggest 45's, as they'll do it easy for you. Is this going to be an everyday car? Quote Link to comment Share on other sites More sharing options...
Toyparts Industries Posted July 13, 2007 Author Report Share Posted July 13, 2007 planning as an everyday... don't mind a car that is a bit of a pig tho... i wanna go half decent thats all... not something that will be average and have to flog to be happy... i wanna build it to get flogged... but i have a daily 121ski for everyday duties so yea...

MRMOPARMAN Posted July 14, 2007 Report Share Posted July 14, 2007 my mate runs a carbed 4ag bigport in a 1.6l hydroplane racing boat with 45mm webers. as redwarf says, 40's will be too small. 45's are the go, but by the time you find a good matching pair, and a manifold to go, you may aswell have gone and bought silvertop quads aqnd a 2nd hand ecu. the webers will support that sort of power not a worry. i can get the specs of his webbers for a baseline for you if your interested. btw he has zero cold start problems, runs clean all the time and rarely needs adjusting. its all in the initial tune, and the quality of webers yoiu've bought.

Toyparts Industries Posted July 14, 2007 Author Report Share Posted July 14, 2007 well there is a kit with manifold carbs and all linkages and shit ready to bolt on basically on ebay for 1300 but they are only twin 40's... so yeah will be looking out for manifold etc or make one up... but yeah as stated before don't wanna go carbs because its the best option just cause it will be a challenge... and the induction sound is second to none not even ITB's sound like em... but yeah keen on specs... i know carbs can be a bitch at time but have a couple of motorbike mechanic mates and know one of the best weber tuners in brisbane...

bullet79 Posted July 14, 2007 Report Share Posted July 14, 2007 4AGZE bottom on n/a motor will robs power, (gze got lower C:R)... hav anyone ever seen a 'KEIHIN' carbs.. Quote Link to comment Share on other sites More sharing options...
andro0o Posted July 14, 2007 Report Share Posted July 14, 2007 twin dellortos ftw. still convinced carby'd 4ag's are gay though. why bother tuning carby's all the time when you can jsut go efi and set all those problems to rest. sure you'll say because its a novelty but its all been done.
