3t In A Ke70

[southcoastrolla]

i just got a very tidy ke70 with a 3k engine and a stuffed auto box. ive found aTE72 T18 SE with a 3T engine and a 5 speed that is full of rust but it is mechanically very good. i don't know much about the TE72 and i was wondering if the engine, gear box, tail shaft, and diff will bolt straight into the ke70. cheers

i think if you get the t18 engine crossmember and the gear box crossmember the motor and box will bolt in.

 

but the diff and shaft I'm not sure about.

does the KE70 have rack and pinion? does the T-18 have rack and pinion?

 

if you do it, stap on a 2TG head to the 3T block.

are you sure your 70 has a 3k?

 

the 70 is rack and pinion, whilst the t18 is steering box. diff and box and whatever fit with different x members and waht not.

 

 

edit: wheres the t18 located, i've got dibs if you decide to sell it.

 

jsut another t series to add to my ever growing collection of them muaahhahahaahhaahhaah...

everything is bolt in! evept maybe the steering..

 

as long as you swap EVERYTHING so thats, enigine, box, tailshaft diff, and engine/box corssmembers and mounts. also put the t-18 struts into the ke70 because they have better brakes. t-18 seats are also alot better than ke70 seat and they will also BOLT IN.

 

i would cut the tabs off that go on the cross member (ke70) and weld them onto the t-18 one so you keep the rack.

yeahsorry its got a 4k. but the engine was in one million bits in the boot. we are building the car for competition rallying so i don't know if we will put the 3t in yet cos will have to pass scrutineering. do you know what gear box is in the t18. cheers

T-50 with the rear position shifter.

on the contrary my latest ke70 had steering box instead of rack and pinion. so if fits if you can be fukd. and you have to machine t18 struts so they fit into a ke70.

that was the ponit behind my post :wink:

got your reading glasses on ;) (hope your not dyslexic) :)

 

most parts will bolt over to the new chassis but that all depends which model E7 you have.

what's required, depends if your ke70 has a rack and if it is a wagon or not.

all te71/te72 have recirculating ball steering

NOT ALL KE70 HAVE A RACK!

if your ke70 has recirculating ball R/B steering it makes it easier to fit the T series engine.

 

the other thing that definately needs mods is the firewall.. as the T50 5speed gearbox uses a hydraulic clutch.. and the pedal box is different than ke70.. you need to drill/cut 3 holes in the firewall next to the brake master cylinder for the hydraulic clutch. you will know where to put these with the te7# pedal box bolted up.. you will first need to drill one hole to let the clutch master mounting stud poke thru the firewall.

 

if you have a rack in the ke70.. keep it!

easiest way to do it (and looks factory too) is either

# cut the engine mounts off the ke70 engine crossmember and cut/weld the te72 mounts on there.

or

# cut the rack mounts off the ke70 crossmember and weld onto the te72 xmember.

when using a rack with a 2t/3t engine you need to remove the gearbox brace that bolts to the engine block as it contacts the rack. also rear of the 3t sump will contact a tiny bit on the rack mount. give the sump a wee beating or section if you need to.

 

the driveshaft varies depending on which gearbox and diff you have. a 3t will most likely have a 22spline T50 (count the output shaft splines where the driveshaft fits in).

up to about 1982, the te71 2t and 2tgeu had a 20spline T50 which will fit the std ke70 (K40/K50) driveshaft. some 1983 te71 have a 22spline T50 like the te72 3t (and '83+ ta61 2tgeu, tt141 3t etc). so you could theoretically bolt the T engine a T50 in without changing the driveshaft or diff.

A 22spline T50 will need the te72 driveshaft if also using the te7# diff. otherwise you'll need to have the driveshaft cut/weld with a 22spline yolk on the front.

 

Different sized diffs have different length driveshafts.. a bigger diff has a shorter shaft. your te72 shaft will be shorter than the ke70.

te71/te72 diff will bolt into a ke70 sedan, liftback, coupe or hardtop but NOT a wagon as they have leaf mounts.

 

if you have a whole te7# as a donor car.. swap the diff and front struts together so it doesnt affect your brake bias. the te7 diff will likely have bigger drums therefore if you only swap the diff.. it'll bias the brakes to the rear so they'll lock up earlier than the front which you don't want.

you may be able to swap the ke70 drums to the te7# diff? or install an adjustable brake bias valve.

 

if swapping in both the te7# struts and rear brakes.. it may help to swap in the larger te7# brake master cylinder too if its not already 13/16 size.

 

Swapping struts... you don't have to mod anything to swap te71 struts in, just swap parts round to suit your car.. you'll need to use the te71 steering arms (knuckles) as they have a different bolt spacing to bolt to the strut. this may then cause an issue with steering arm length if you have a rack.. because ke70's with rack often have shorter steering arms than te71. there are other arms available that are shorter to suit tho. also...

79-82 ke70/te71 etc have equilaterally spaced bolts on the strut top-hat (at the top of strut).. '83-'88 E7 have unequal spaced mounting same as ae85/ae86. use which ever one fits your car. ie if the struts you're putting in are different.. take the ones off your original ke70 struts and fit them to the te71 struts.

the springs on te71 struts should be stronger to account for the extra weight of the T engine. if you use the ke70 struts/springs and your front end drops a bit lower when fitting the 3t... you'll know why heehee

 

the wiring looms are a little different but not heaps between ke70 and carby T engine (efi is totally different). and also may have different holes in the engine bay that they come through. use the te7# loom if you can as it'll have all the correct lengths of wire etc. you may need to cut extra holes in the engine bay inner guards for it... and take your dash out to fit the loom under there.. it takes a little while.. and if you do it make sure to label the plugs when you unplug them from te72 so you know what they connect to later on.

early and late E7's have different plugs so if you're changing between the two.. you may have to swap the heater fan, guage cluster, heater control panel etc so the plugs match up.

 

sedan and wagon have similar dash.. whereas liftback, hardtop and coupe are similar to each other. so can't swap dash/instruments between say a sedan and liftback due to different dash shapes.

 

then theres the radiator, exhaust, ignition etc.. use all the te71/te72 stuff

 

Hope that helps!!! i've been thru all that conversion stuff before in my own ke70 so if you need to know anything, fire me a PM.

I wrote this also.. so have a read. it should clear more things up requarding fitting 2t/3t into a ke70

tho i went from a 4k, to a 2tgeu, to a 3tgte

oh and for you left hook drivers.. this applies to RHD!

cheers man. you have been very helpful.
