20v/ke20 conversion

[dan05k]

has anybody out there got any info on putting a 20v into a ke20?
i have rwd engine mounts and gerbox from a ae71, do i need to make a new gearbox crossmember?
i have also heard that the plenum above the rear trumpet may foul the master cylinder, can anyone confirm this?
i have alot of info in regards to cooling system, so no problems there, just concerned about the actual fitment of the engine and gearbox.
any info would be a great help, thanks.

search next time mate.....

thanks, ive seen that article. its seems to mailny deal with the cooling system side of things.
like i said, thats not the problem,
was more interested if anybody had problems with master cylinder clearance and crossmembers, ect. in a Ke20 specifically, as the engine bay is a bit smaller than that of the celica in that article.

i think you will find that the car in that article is actually a ke20 dude im pretty sure ta22's dont have those top bonnet vents like there is in the first photo.

the only real way your going to be able to tell is if you mount it all up. you shouldnt have too much of a problem with brake master but you will probably have to have a remove clutch master.

my 20v clears my brake booster and clutch master only jsut with the 45mm trumpets on it.

ok, so this is thread number two for this....
why not keep it all in one thread?

i stand corrected, does appear to be a ke20. still he dosent mention what crossmember he uses or anything else other than cooling system issues.
yes, this is a second thread. reson for that is i have posted on a few different forums and forgot i already posted one at toymods, sorry about that.
i have taken into consideration info provided before, one guy said he has some engine mounts to fit a 4a onto a crossmember orginally desiged for a K series motor.
waiting for a email from him now.
anyone else with info or experience with this conversion, input would be greatly appreciated.

well.. AE70 mounts are further apart than KE70... and KE70 are further apart than KE20, so it stands to reason that AE70 mounts are much further apart than KE20.

KE10 is different to KE20, KE70 is different again, but am not sure about KE30 widths.

just do it the easy way.. get motor, get crossmember, space engine off crosmember in correct position and angle and get thick cardboard and make up correct size and shape mounts then take to engineering shop/mate and get them welded up...
mounts are easy.... just need to be the right shape... but the right shape is not too hard to work out

or check the Flame in members rides. KE20 with 4A and some other crossmember perhaps (can't remember )

he'd be using standard crossmember, ta22 rubber mounts and custom side engine mounts which arent very hard to get made up.

if you use AE71/AE86 side engine mounts and weld in the matching crossmember mounts the engine will sit too high and you probably wont be able to close the bonnet.

the block is the same as any other 4age as far as mounting is concerned so if you currently have a 4age bolted into you ke20 you should be able to use the same mounts.

pretty much one of the hardest parts of a RWD 20v conversion is sorting out the cooling issues, apart from that obviously you have to worry about clearance issues for your throttle bodies. take some measurements of your engine bay from the crossmemeber ect from the block to the area of the brake master and ill see if i can get some corresponding measurements of my 20v once i get it back from the exhaust shop.

AS Dom said you need to get custom mounts made. I have a ke25 w/4age 16v, i got custom mounts made also which allowed me to use the standard gear box x-member. U can either do them yourself which isn't too hard if you've got a hoist and a lot of patience! Or get a engineers place to make them, but that is gonna cost you! Me and my brother tried to fit a 20v in a ke20 with my mounts but found that the head is a bit longer than a 16v so it didn't fit.
Anything else PM me,

Yes i made KE70 crossmember and allmost full steering ans suspension to fit KE20, BUT mu engine mounts are welded straight to chassis rails!

Maybe smartest thing would be getting a AE85/86 crossmember and bolt it on. This way you get right engine mounts and steering rack at same time(only the track width is wider on KE70 than KE20, fwd wheels or flares needed).

Assuming this is legal for you... mine it would not been, but Flame is an Track car

[oldcorollas]

oh, i forgot that

AE71 crossmember doesn't fit between chassis rails of KE10... ie the outside of the mounts foul on the rails by an inch or two (iirc).. as KE20 rails are only 0.5" wider, methinks they would also foul...
KE70 fits tho, but then the mounts are closer in and you need custom jobbies anyway

[Toycrash]

Eh... Isn't KE,TE and AE 7-series the exact same body and rails?

Mine didnt fit straight, but i only had to cut about 1/2" per side and make new holes to crossmember. Then again, i didnt need to make it look like a factory fit

Anyhow i will make the same crossbreed to my KE26 eventually, that i have to make look like stock tho...

[oldcorollas]

in the 70 family they probably are, but they are also angled out, ie the rail bolt points are 30" and 31" apart.
the KE30 (and i think KE20) and 28.5", and the KE10 (and maybe KE20) are 28"
this is for the bolt spacing (ie the crush tubes), not the distance between the insides of the rails.

edit: relating to \/\/\/\/\/\/ the angled out rails measn the ENGINE mounts are further out and don't fit between the earlier rails.. but as said before, the KE70 ones do.. the AE71 (and i imagine the AE86 ones) do not fit KE10, and will probably not fit KE20.. but if someone wnts to actually take measurements, please do..

[Toycrash]

in the 70 family they probably are, but they are also angled out.

So? Pay attention mate

Mine didnt fit straight, but i only had to cut about 1/2" per side and make new holes to crossmember

So the old holes were gone and i made new holes to suite KE20 rails

Mike your forgetting that you had to redrill your mounts when u put ur motor in too! so it probably would have had clearance.....
