hey people
after seeing a lexus V8 in the back of a kombi and hearing the note of the engine i love it!!!
anyone have any good sites on this conversion and secondly my question about the renualt 5 speed which is making its way into a few kombi's anyone know anymore of it??? i think bris conversion are making a kit?
cheers

dellow and caslemaine rod shop both do bellhousing kits to fit the 1UZFE (lexus 4.0L) V8 to the Renault R30 gearbox.

awesome conversion! the renault box handles it no worries according to the guys at http://www.carbontech.com (.au?) who make the lamborghini replicas using this combo.

the diff can be flipped with no major drama other than the speedo drive on the box no longer mating, but as VW uses the speedo off the front wheel anyway it's no big deal.

you can get a 1UZ front cut from a Crown or Soarer for under $2500 these days which gives you every electrical gizmo to run the motor complete, all you'd need is the renault box and fabricate the mounts and linkage. apparently the 100mm kombi CV's mate straight up to the R30 drive flanges, though I don't know if the width of the box is the same.

The renault box you need is designated as an UN1 gearbox, and is found in the R25, R25 turbo, R30, Audi 100 and Audi 80 (I think) as well as some renault vans. some are LSD and asll have different ratios, so some time with google is needed.

top idea for a kombi conversion! you'd be damn hard pressed to find a better combo I recon.

To date I have killed with this donk

3 x 9 " usa diffs
4 x trick usa autos
4 x tail shafts
2 x trees
1 x river bank
3 x rear ends snaped
2 x usa drive shafts 4 k +
4 x usa stub axels 6 k +
6 x tyers
2 front ends

and the toyota has not stoped once

to let you know when you go to the bank !

What sort of money do these boxes go for

the gear set cost 4 K + shipping
the box is hard to find , mmm my shed has two !

The r30 box cv these are made 2k +
you must under stand this IS BIG HP No bull shit Our stock donk eats a 5.7 holden donk no problems !

these engines produce around 190Kw right???
seagull u dont reacon the box will handle the power of the V8???
cheers
rhys

you the diff that I have replaced ,we went 500mtr snaped the pinon like a carrot ,you can not buy any thing better in the world .I have seen many blown boxes ,we have raced ours for three years now .The r30 will not stand the power !!!! thats why I have the renault turbo gear for sale .DONT WAST YOUR TIME LOL !

made to manual shift bolwn that up gee I have lost count now .

well obviously i will not race my kombi just for cruisin in and occasionally spinning the wheels (being 17 you do these things) so yer it would handle it ok then hey?
cheers
rhys

would give you that boost , so would the MR2 1.3 turbo kit to kombi :thumb:party

are you sure it's a UN1 box and not a 359?

359 is R20 and won't cope with huge power.

even ford 9" diffs will break when given enough abuse.

ok so i wont to look for a R25turbo box or the R30 box???
you dont know what cars these came out of do you?
cheers
rhys

if you want to use a renault box, then you want a UN1 box, not a 35x box. UN1 is from Renault 30, Renault 25 turbo and a few others

Renault 20 and Renault 17 etc used a 35x box and it will not cope with big power.

thanks again i will get them pics over to ya ASAP
cheers
rhys

I know some on that has the R30 box grafted the 9" to it and wears it out in one race ,as the 2K clutch plate .
racing costs $$$$

I found you a box secoh its in the for sale postings seagull

use guys must race hard!!!
cheers
rhys

seagull thanks I saw that, it's about $1500 overpriced for me though.

how does one graft on a 9"? if it that sort of thing isnt done to very fine tolerances it'd last 30 seconds.

abuse will kill anything too. a G50 would last no longer.

This car is Wa number one ,It not abuse mate its HP I try and a photo of it .It is no where close to me but I will get there one day . If you find a R30 close ratio box ,get two I have never seen one for a 1K the gear set we have is worth 4K ( it is new ) the box does brake ,the 2ltr turbo renault motor we had build would not go far with out shiting the R30 ,there has been many that tryed over here . The box also had oil injection fitted .
They are not strong at all !!
The 9 " conversion is IRS power turbo V6 nissan .

I suspect your comparing apples and oranges in what most of us want to use one for.

I've had enough. you people make up your own freaking minds and do your own fokk3n research.

i agree may your R30 box come at the right price and you never have to pull it apart
if you do find on for a 1 K let us all know seagull :jesus

so far I have a R20 359 box ($200, came with a complete car which I sold $200 of bits off) and I have lined up a audi 5+5 5sp transaxle in a complete driveable and registered car for...you guessed it....$300.

neither are as strong as a UN1, but for street use or a light car on the circuit they might be fine. And a damn sight cheaper than $2500.

we'll see. this is all meaningless until I have one in the car and am flogging the arse off it.

Hi

Slightly of the subject, those front wheel drive Merc vans have a 5 speed transaxle in them, wonder what they are like, strenght and ratios wise.

1302Steve

apparently the ratios are pretty wide, but someone said they were actually one of the reccommended boxes, though I can't remember if it was UN1 or Audi 016. For some reason UN1 rings a bell....

Hey guys found this for sale, it's not mine, by the sounds of this thread it's cheap if he still has it make an offer?

Renault 25 (UN1) gearbox
Clean box come out of wrecked car.
$1600 with one drive shaft and 2 stub axles.

Ok so lets talk Box's

I see the UN1 is the pick for some but I have to ask why ?? With a 3.88 diff centre electronic speedo sender anmd gear ratios that don't really seem what I am after.

The UN5 seems liek a better option. It take 300 honest HP and still goes strong. Has a 5.85 diff with a good set of 5 speed ratios and a 0.683 5th gear. LSD is also availible and a good option. As they come out of the Reno Master Commercial Van they have seen some heavy work already an dproven themselved quite strong.

AT 720 mm long with 220 of these being face to center of axle and 500 from centre of axle to nose cone and aside cable shifter there are a few small problems with the conversion. Namely an extra 200mm to cope with ..

But I have seen them fitted so it can be done. Cost wise I can get them all day long at $1650

Here it is in a Kombi ..

I was quoted 3K at xmas time
the gears are wide apart ????
Adapter plate MMMM here we go again ! another late night in the shed .


Can you get some mesurments of the belhousing on CAD ?

I do some asking over here as to there bad points ,ok seagull

so thats what was in that bus i wasnt sure of the box that was in it (secoh this is the one i said i had pics of!)
whats the distance from the bellhousing to the centre of the CV???just curious on where that extra 200mm is!!
cheers
rhys

Gee, thanks for telling us this sooner!! :P

Has someone already made a bellhousing for them, or do I still have to do it from scratch?
