lehparmac Posted August 18, 2010 Report Share Posted August 18, 2010 Hey Guys, I have a Te72 T18 completely stock, i was just wondering is it possible to rip all the emissions stuff off to clean up the engine bay and is it worth cleaning up the Carb? I live in QLD and not sure about all the emissions laws ect... I don't know much about the 3tc's and am on my p's so can't do to much with it. In lamens terms, I want to make the engine bay nice and clean and maybe get a bit more performance out of her. Maybe a guide on how to tune the Carb would also be appreciated and also (N00b question) what is draw through to the Carb? (not sure if that is what its called) Cheers Tazz Quote Link to comment Share on other sites More sharing options...

The way I did was turn in the idle mixture screw till it runs rough then very slowly turn it out till it sounds smooth, then turn it out another 1/4-1/2 a turn. Thats how I did mine and now I'm getting about 10L/100kms, which I think is pretty good. If you live local I could give you a hand, where in QLD are you? Also got a picture of your car?

I live in Ipswich (unfortunatly) lol ill put some pictures up tomorow, its not very pretty yet though. isnt there some sort of ecu for the emissions? also what air pump and which lines? 3tc's arnt my strong point, I'm used to the ol' 4k motor. How do u reset dizzy points and timing? sorry if I sound a bit dumb but ive never played with carbies and dizzy's. thanks heaps for your help Tazz Quote Link to comment Share on other sites More sharing options...

Timing is again easy with the use of a timing light. Quote Link to comment Share on other sites More sharing options...

Timing is again easy with the use of a timing light. sweet thanks. the reason i think there is one is because there are sensor type things with wires hooked up to them lol i will take photos tomorow to explain what I mean. Is there a way of doing the timing without a timing light? Do you have a website that has some good information on it that i can use cause i can't find anything :D Quote Link to comment Share on other sites More sharing options...
lehparmac Posted August 19, 2010 Author Report Share Posted August 19, 2010 Heres the pictures you asked for... again, not very pretty the rear end has needed some personal attention as well :D lol and can someone tell me what all the things marks with red circles are, i have no f@$king idea. ;) Quote Link to comment Share on other sites More sharing options...
ke70dave Posted August 19, 2010 Report Share Posted August 19, 2010 (edited) the thing in the 2nd picture, attached to your block, is your oil pressure sender. (either a guage or light in your dash, prolly just a light) the other thing, I'm not sure, i had one on my old 4k, and unplugged it...and nothing changed.....its connected to the carby yeah?

Evan G Posted August 19, 2010 Report Share Posted August 19, 2010 if its a 5 speed, it has a switch on the box and opens one of those valves witch makes the engine run lean when cruising in 5th Quote Link to comment Share on other sites More sharing options...

Evan G Posted August 19, 2010 Report Share Posted August 19, 2010 mines plumbed under the battery so i could pass the roady LOL! i havent noticed a difference Quote Link to comment Share on other sites More sharing options...
lehparmac Posted August 19, 2010 Author Report Share Posted August 19, 2010 mines plumbed under the battery so i could pass the roady LOL! i havent noticed a difference can i just rip it out after i get the roady? or is it pointless removing it? also there is a red wire and black wire going to the carby, what are they for? i know i must soud like a dick right now but i honestly know f@$k all about carbys, just the basics of how they work.

Thank you so much for your help that explains alot :D yeh i didnt think it was worth pulling them off, i just like the look of really tidy engine bays. what type of weber would be the best, side draft or just standard? thanks again for your help.

ke70dave Posted August 19, 2010 Report Share Posted August 19, 2010 (edited) maybe something like this? http://www.rollaclub.com/board/index.php?showtopic=42930 i dunno ive never played with webbers, or 3tc's, but thats what i would be looking at. keep it looking pretty standard as well. you just might have to get it rejetted for the 3tc, i dunno. edit: here is an even cheaper one, though may need a rebuild apparnetly. http://www.rollaclub.com/board/index.php?showtopic=42669 Edited August 19, 2010 by ke70dave Quote Link to comment Share on other sites More sharing options...
