Is there such a thing as a dash that is not cracked? Mine is more like cracks with a bit of dash on it.

Mine had no cracks. They do exist.

 

I know the 1UZFE is a good engine but it's so, um, Toyota. Have you ever heard a Trumpy with PI or triple Webers with a 6-3-1 manifold at full song? It will make your pants wet. I miss my Triumph and part of the reason I loved it is the shit engineering. I loved spending my time trying to make an overweight badly breathing cast iron relic do more than it was designed to. 

However, if you must, I endorse the comments about using an R200 and upgraded driveshafts and sticking with a stock(ish) rear end. The Triumph setup works as well as any trailing arm design.

Do you have any photos? I feel some dejavu... I might have asked in a previous thread.

Which sump did you use? My engine is a front sump, but I managed to source a Soarer 'rear' sump out of 'Murica. Initial measurements make it too close to be sure(current engine is in the way of measuring). So it will either just fit behind the cross member, or the crossmember/sump pan might require some modifications.

Yeh, I've heard the Nissan diff is a common upgrade. But I don't know if I will find a suitable ratio without having to find some rare as obscure model.

Have you done any final drive calculations with wheel/tyre size and your ideal engine rpm at particular speeds?
Because your range of suitable ratios is quite broad due to the difficulty of finding a suitable diff which offers a low 3 ratio.
You might find that around 3.5 is actually suitable.

Or you could find any other IRS diff head and axles (BMW, Holden, Toyota etc) that is relatively easy to obtain and look at fitting it, if it comes in the ratio you desire.
I wouldn't bother fitting another IRS rear subframe or rear end into your car because the one you have will be more than adequate for a 1UZ.

Just done some quick spreadsheeting. Ideal ratio are between 3.3 and 3.5. This gives me 100kph at 2600 - 2750rpm in 5th. Internet seems to think the 1UZ likes this rev range at 100kph.

My lexus to triumph sump was a 10mm thick flange with the pick up points for the trans at the back end, then welded the pan off an old small block chev i had floating around and modded pickup to suit.

If you have a front sump supposedly possible to carefully cut the gearbox mounts off the ass end rotate the thing 180 degrees then weld back on for a rear sump. Not forgetting pickup mods too. Pretty sure steering rack will be in your way if front sump is tried i could be wrong though.

Triumph 2500 was 3.54 iirc.  Nissan Z33 350ZX (2002-2009) manual had R200V with 3.538, auto had 3.357, should be reasonably easy to find.

Triumph is 3.45:1 but yeah a 3.357 auto Z33 rear end would be ideal. Have seen a few of them being parted out too.

Also the IRS is not good it's flappy chicken wing semi trailing arm insta-toe camber gang garbage. But it's sweet for fitting wide wheels. Doing away with the shitty rear hub arangement would be dreamy to boot. But fitting another subframe is gonna be a massive dick of a job. Time is free I guess.

I have an acceptable center console you can have. It isn't cracked near the choke but does have a mangled hole for oem demister switch and the holed for the gear boot clips have done their usual shit themselves thing.

Look forward to seeing a UZ in the hole. It's my ideal swap too.

I have a good center console on the way, thanks anyway.

While your attacking the firewall should recess it 100mm so a Barra will fit.....

Probably better to fit heater unit out of something 90's spec and Japanese the triumph units fill with leaves and rust out, or the internal gates seize and give you full time hot feet or wind in your face.

I have considered both of these things. If I recess the firewall, I'll have to change the heater because it won't fit anymore.

But retrofitting a modern heater to the existing inlet hole and vents seems like it could be a lot of work.

Mayte,  should be a dawdle by comparison. 

Nar. Engine transplant is easier. Just needs brackets, all the connector bits like hoses/wires are flexible so stuff doesn't really need to line up.

Heater is big fucking plastic thing full of flappy doors to make hacking it up not really feasible and vents in the wrong place but you can't move them because flappy doors won't work right and mechanical levers for flappy doors that you need to actuate somehow.

I think my options are:

  • Fix existing heater maybe try upgrade motor to insane brushless mode.
  • Get better condition std heater maybe try upgrade motor to insane brushless mode.
  • Replace with something really basic that only does the windscreen. But then I am left with useless vents in the middle and on either side of the dash.

Remember I don't want this to be another racecar.
