The standard 'Supra' box (W55 etc) is more on par with the T5 and a lot cheaper, the R154 is commonly called the 'Supra Turbo' box

This thread should help with TKO info.

Evan was also selling a W58 conversion.

can anyone estimate the cost of the other parts that would be needed (Clutch kit, conversion kit etc)?

Could be a bit expensive (especially if you have a Holden pattern block rather than Chev), but no different to any other gearbox so has no bearing on which one you choose. All parts readily available.

I paid $800 odd (includes shipping and tax!) for my Muncie conversion bell housing from Dellow, this is the major saving if you have a Chev pattern block you can get something much cheaper. Clutches have gotten expensive, figure on $600+ for a full kit or $250 for decent heavy duty driven plate if that's all you need to change. Driveshaft yoke change could cost another couple hundred depending on what you have and what you can find cheap. Add some more for bits like clutch fork/mechanism and pedal if you need that stuff too.


Oh and to answer your question about the six cylinder Ford T5, its popular because the input shaft length and shifter position better suit the Holdens. Internally the boxes often have slightly different ratios between six and eight (and between Holden and Ford) but are basically the same.

Not to mention T5's can be tricky to find and expensive... especially V8 Holden ones

All the 6 cyl ones get snapped up here for the sallon car racers... they put PPG gearsets in them (about $5k) and race them to death
But they have alittle less torque than a big 8

Theres plenty of options... none are easy unless your wallet is fat

A forum member here recently upgraded his steel case celica set up to a R154. The box cost him $800 from memory.
The beauty of using the 154 is you can do a pretty cheap conversion as many of the bits are common to lesser celica and W series boxes. These bits come up for sale quite often.
My 154 has survived over a decade and 80,000k behind the 383 in the sedan despite the sticky drag radials and many a 1-2 slam shift.

I paid $400 for a R154 at local wreckers (I'm well known there, he wanted twice that) $80 for used bell housing on fee by (suit trimatic block) Statesman tailshaft $50 from same wrecker (will be cut down) $140 for front yoke. Haven't got to rear yet as thinking of BW diff. All to go in LJ 2 dr, took about a yr to get bits so far.

I picked up a 2nd hand r154 box from a jap wrecker on ebay for $750+freight, came with warranty. and its fine. so people paying 2k for a box are just not doing their homework.

Yes and no, if you have the luxury of time (or luck) to find the right conversion bell housing, clutch, driveshaft etc components then maybe around $1K but it wouldn't be hard at all for the complete cost to blow out to $2K+ if the gearbox itself is $750

[76lxhatch]

this is for a W series box.

Ah sorry I did misunderstand

How big is the R series compared to a W series??

Cheers.

A bit bigger and bulkier but not so much that it should cause fitting issues:

(main thing is the longer input shaft/bell housing)
