Wow! What clucth are they running? I know Blizzy was thinking about using the transmission.

About 500 USD, not bad for us who cant afford a 2k tranny!


So what clutch now?

just BTW you can bolt up an r154 to eric's adaptor plates too they are the same bolt pattern..... no one seems to understand that

Edit: you can also make any regular r154 clutch work easily with those adaptor plates but i suppose no one has figured that one out either

xirforever

well if someone was going to use a r154, i would rather use a new bellhousing than buy adapter plates

how can you make regular r154 clutches work easily? You need a special flywheel.

no you can use a stock flywheel and get it drilled or call up fidanza and get them to drill the pattern on a mk3 supra flywheel then there is a little something else that helps as well but why waste the money on a new bell housing over buying some plates???? the bell housings from australia are way more expensive.

There's no magic way to make the SC400 or GS400/430 a manual transmission. There's always going to be work and expense involved in a manual swap. We firmly believe the adapters are very competative with the bellhousings from AU in both price and ease of use. The thick of it in the case of the V160 is the cost of the tranny, plain and simple. If that can be overcome, then the reward is greater than using any other tranny if nothing else for the fact that your car runs the V160 6 speed.

I personally would not redril a 6 bolt flywheel to an 8 bolt pattern, but thats just me. Nor would i use a fidanza flywheel.

Also, i think you are forgetting about a very important piece on the flywheel called the ring gear....

well since you have something against fidanza call up any other flywheel company most will be happy to build a custom fly wheel bolt pattern ring gear and all depending on who you go with its not expensive. ive had it done before. erics plates really are nice and easy to use.

as for the conversion kit that thor company makes it seems pretty decent but im not a fan of the release bearing system they use. no real reason behind it ive just has bad luck with them in the past.

xirforever

that is essentially what i will be doing, but with RPS, and i will be making a mock up flywheel first for them to copy. Ive just heard bad things about fidanza and it makes sense what people since, at least the physics part.

Unfortunately, this adapter plate is no different from Eric's in that his would bolt to any JZ tranny (V160, R154, or W58).

The issue is the clutch-flywheel as most of us do not need the 1000hp capacities of the 13lb V160 clutch in Eric's kit (although it is indeed totally bad ***).

I have emailed those British folks to see if they have a clutch-flywheel combo available for the 1UZ/R154 union. In addition, I emailed a handful of custom flywheel manufacturers in the states to get a rough estimate on making a custom flywheel for either the W58 or R154 for the 1UZ.

The advantages to the W58 and R154 are clearly practicality. Both are cheaper than the V160 with more realistic horsepower capacities (375+whp and 550+whp respectively). Both were also mated to rear ends in the range of the 3.91 drive ratio on the 1UZ (~4.0 on the MKIV W58 and 3.7-3.9 on the MKIII R154). Thus, no rear end swap is required to maintain street manners. In addition, some driveshaft manipulation from either the SC300 or Supra driveshaft may be able to bypass the necessity of a totally custom shaft.

If a custom flywheel can be sourced reasonably, I will begin trying to make it happen. I think the W58 makes the most sense since it will come through the tranny tunnel without modification and the shifting is super smooth in relation to the R154. Ultimately, I have a 260hp n/a car that is not going to see F/I for some time. I just want to throw a few gears around.

I will keep everyone posted on what I hear.

Buyer beware when dealing with Thor Racing, and that's all I'll say about it. Consult mkiv.co.uk to read more.

custom flywheel? lol...

expensive. i have already spoken to a few companies personally. Most flywheels companies get their flywheels from other companies. I heard there was 1 major aluminum flywheel supplier in the USA.

anyway, if any of you can get us a custom flywheel and its not too expensive i will be down to buy one as well.

flywheel companies are quoting me upwards of $1500 for a custom flywheel with 12-15 weeks of downtime. this is astounding to me.

a custom clutch is even more impossible as people were just telling me, "No."

I may have a couple more tricks up my sleeve...

ps. thor racing admitted to not even having had success with their own 1UZ Supra and an R154.
