okay to summarise, we have so far

1UZFE > T5
1UZFE > T56
1UZFE > TKO Tremec
1UZFE > R154 (being measured)
1UZFE sump flange
1UZFE header flange
1UZFE CAT flange

awaiting

1UZFE > W58
1UZFE > V160
I am alittle confused...

Is someone making the adapters or are these just PDF files to make your own. I am really interested in PDF files for the T5 trans if someone has them.

Just picked up a W58 so I'll be available for bellhousing/tranny measurements as well... if you need any more after the post above.

Drawing for 1uz to un1

Hi Striker, I have a 1uz joined up to a 016, but have been thinking about changing to a un1, to escape the useless 016 1st gear issue,would you be able to send a copy of the un1 and un5 that would be a great help. Sorry i don't have a drawing for the 016 it was custom made up but i could measure it up if someone could convert it to cad format.

Id really like to get hold of that un1->1uzfe plate dimensions too. It would save me a ton of trouble to just have the bolt positions etc to put in the mill to cut a plate out...
Lambo, not sure the un5 will be of much use to you. The un5 variant has a *really* low diff ratio and the diff bearings are a different size to the un1/369's, and nobody makes a aftermarket diff for them. They also come with two bellhousing patterns depending on what year the donor renault master van was.

for the UN1 conversion try Dave Short at countess mouldings.

his prices weren't to high I recall, he used Nissan clutchparts iirc

I don't have the UN1 anymore, i bought a G50.

accurate measurements

Okay - this may be obvious to some, what is the best way to measure centre to centre accurately with large items like bell housings? I'd hate to get the measurements wrong and make a bellhousing only to find it did not fit. Edz

hey Edz

turn down the correct amount of bolts down into a very sharp point, place those bolts into the bellhousing, put the belhousing down on a piece of new alloy sheet, and tap the belhousing around the bolt heads very gently so the points leave a mark. you have now got a template of the bolt pattern.
if the holes are not tapped, I usually turn plugs on the lathe that fit perfectly into the bellhousing holes, and centerbore them with a 1mm drill bit, I then tap the plugs into the bellhousing, put the "to-be" adapterplate on the housing with strong C-clamps and carfully drill the 1mm holes through using the plugs as a guide for staightness.
this is by far the quickest way to do very acurate work, but takes some time and you do need to have the right tools. best thing is you don't need to draw anything.

other way is to measure up the outer edges of 2 holes and calculate the lentgh inbetween them by taking of 1 hol diameter.

best obviously is to get it measured up by someone with a laser or pointfeeler(whatsit in english) CNC like bench, out comes a file that can be read by most CNC machines and you can go in production at once.

Yes so far I have used some 1mm alloy sheet..
Lucky that crank and Powerglide dia is the same..
After cutting hole in sheet the same size as centre ..
Fitted it to motor, drilled holes each side where bolts are and fittted some tight bolts with big washers.. Then drilled the other bolt holes including dowel if there is any on motor side...
On the Powerglide [GM 2 speed auto] I started at dowels, then drilled out holes for auto.. I made them 2mm larger and used metric sized bolts so there should be no clearance issues..
Done much the same with torque converter..
I used 13mm X 100 mild steel plate to adapt between the two..
There is approx 30mm gap between 1UZ bolt pattern and Powerglide which is larger.. I had to cut a small circle out at top of adapter plate to clear starter motor.. From memory I have reversed the bolts that go through starter motor so I don't have to pull adapter off to get to starter motor bolts.. By using larger bolts, drilling out starter motor threads and tapping motor..
Did I have to explain what a Powerglide is ??? Lol..
