camerondownunder88 Posted June 26, 2006 Report Share Posted June 26, 2006 Hi rolla fans, About 3 months ago now I was given a KE30 rolla with a 3K motor in it sporting a 100% stock parts and a K40 trans and standard axle. But the car has 375,000 KM on it and has never had a rebuild and is still going good and blows no smoke. But it is starting to die now :) As in a cold morning I can run battery flat starting and it has lost nearly all power and the clutch is heavily worn. So I figured time for a rebuild but then though it easier to install a new motor. I was able to pick up a 4K that has 100,00Km on it and a 6 spring racing clutch after market hardened valve seat and a minor head shave for AU$50. But first a few questions. It was mounted on a 5 speed box so will the input shaft fit my 4 speed box? Also my KE30 is a 1976 I think off top of head and it is from a KE70 built in 83 so will it all go in? Also I noticed the pollution control on the motor is a nightmare. Can I use the one of my KE30 motor that is horrendously simple compare to it? And when removing the 4K motor from the donor car is the anti pollution system hooked into any body bits or can i leave it untouched on body? Also for future mods can I just remove the timing chains from the 3K and place on the 4K motor and the head with easy and no fuss? Also what model K motor had the electronic ignition as I want to ditch the points system as they are a shit of a thing to work with. Also if I use my 3K head on motor what HP will I expect to see from the motor? Thanks Cameron Quote Link to comment Share on other sites More sharing options...

Also I noticed the pollution control on the motor is a nightmare. Can I use the one of my KE30 motor that is horrendously simple compare to it? And when removing the 4K motor from the donor car is the anti pollution system hooked into any body bits or can i leave it untouched on body? Lose the pollution gear and use the carb off the 3K. Put a kit through it, or fit a Weber. (Alot of people in here use them, I don't, I'm not a fan) Also for future mods can I just remove the timing chains from the 3K and place on the 4K motor and the head with easy and no fuss? Also what model K motor had the electronic ignition as I want to ditch the points system as they are a shit of a thing to work with. Also if I use my 3K head on motor what HP will I expect to see from the motor? Thanks Cameron Don't ever put a used timing chain on another engine. Buy a new two row, they're not that expensive. 3k head will bolt onto a 4K. Wiki has more info. I also haven't had much success with electronic ignition on my race motors. I still use points and have no issues with them. They came on 5K engines and some import 4K's. Call someone like Just Jap. Power increase by a straight change over will not be great. There is a good "how to" bit in the wiki. R Quote Link to comment Share on other sites More sharing options...
camerondownunder88 Posted June 30, 2006 Author Report Share Posted June 30, 2006 Hi, Thanks for all the replies. Unfortunately my friends mum wont let him sell the corolla in pieces no more ;) but a whole car, but for whole KE30 he wants $300 not bad but. I got my corolla..lol So I went to the wrecker and asked for a 4K motor. They had one minus carby, distributor and pollution gear (no loss.lol) $380. GET REAL. So for now ill stick with my 3K motor. As I see the 4K is only 200cc bigger. As I am short on money so ill leave it for now. But I was curious to know is the 4K just a bored out 3K block or did Toyota redo a whole new block? And does anyone know of a person in the Brisbane district that has an old KE1X or KE2X that would have one for sale? As I prefer the body shape and there smaller so I would like to do one of these up. Also reading at Wiki the 2T-G motor produced 124HP in the KE30. Can these motors fit onto the K40 trans or were they a different transition? As I would like to get one day an old KE1x/KE2X and have a hot 4K or 5K motor in it or if possible with minimal hassle a 2T-G motor. But for my final question the 5K to install legally into my car I need to upgrade brakes but can go to a 4K with no changes so for power would it really be worth adding a 5K motor to the car? And can it be done up as much? Or if possible has anyone used a 7K? Thanks Cameron Quote Link to comment Share on other sites More sharing options...
irokin Posted June 30, 2006 Report Share Posted June 30, 2006 T motors use T series gearboxes i.e. T40, T50, but off celicas etc not AE series RWD corollas Quote Link to comment Share on other sites More sharing options...
pozman Posted July 1, 2006 Report Share Posted July 1, 2006 T motors use T series gearboxes i.e. T40, T50, but off celicas etc not AE series RWD corollas what is the difference between the celica ans ae series boxes, is it just bell housing?

irokin Posted July 1, 2006 Report Share Posted July 1, 2006 what is the difference between the celica ans ae series boxes, is it just bell housing? While Ive never personally compared them I think theres a slight change in the positioning of the input shaft. Someone like Demuire whos used both boxes behind an A series (there were problems with the celica T50s if I remember correctly) will be able to comment with more detail.

Redwarf Posted July 1, 2006 Report Share Posted July 1, 2006 I know AE86's have a larger input bearing, and a T housing won't fit where an A housing will. Hence my t bell housing wouldn't fit Tony's box when we tried at Willowbank. Quote Link to comment Share on other sites More sharing options...
love ke70 Posted July 2, 2006 Report Share Posted July 2, 2006 celica boxes have a 20 spline and ae boxes have 22 spline shaft can't remember which shaft hehe Quote Link to comment Share on other sites More sharing options...
bruce Posted July 3, 2006 Report Share Posted July 3, 2006 I think the gear shifter of the celica gearboxes are further forward than the AE gearboxes. If a AE gearbox is put in a ke3x, the shifter hole might need to be cut. There are some pictures of it here: http://fookseung.fotki.com/automotive-1/ke35/engine_install/ With the celica gearbox the shifter comes out through the original shifter hole in the ke3x. I wonder if the extension housing can be changed over from the celica gearbox to the AE gearbox, so that the shifter position is in the right position for a ke3x? :dance: Quote Link to comment Share on other sites More sharing options...
camerondownunder88 Posted July 3, 2006 Author Report Share Posted July 3, 2006 Hi, Nice work on the rolla in the photos with the celica box going in. I think I would rather stay with the K range of motors so it is easier to get rego as in QLD if u put wild seat covers on u risk having to up grade your car to make it legal it is so tight..lol But I was able to find a good wrecker in Ipswich today that sells a fair amount of corolla stuff so I am trying to get an old KE1X or KE2X from him as I like them more as there lighter so faster. But I saw one guy said that he was at willobank once and couldn't get a box to ft in his rolla. Do you guys meet at Willowbank as I am a 10 minute drive away so would love to pop in one day? Also with the distributor off the 5K motor will it fit into a 3K with no hassle eg gear on end of shaft ratio..etc as I want to go electric dizzy in rolla to ditch points . And I have heard from some people that the end of the run KE70 with the 4K did get some electric ignition modules in them is this true? Thanks Cameron Quote Link to comment Share on other sites More sharing options...

Do you guys meet at Willowbank as I am a 10 minute drive away so would love to pop in one day? He wasn't trying hard enough. I have a T50 in my 20, and a T50 in my 55. Bit harder to make them fit into a 10. Quote Link to comment Share on other sites More sharing options...
