About time you updated your cars! Ever get one of the people who you helped with your cars to help you with the 940?

I'd run the 300mm clutch, going bigger just because causes more delays, though the motor does look crusty.

Dauntless

The NPC 1300mm kit is also 300mm, however it comes with a billet flywheel. They are an off the shelf item and readily available, unfortunately I don't have the budget right now.

Factory 300mm clutches are known to slip at about 450Nm, and I plan to exceed that figure by quite a bit. The 1HD-T currently has an Exedy Sports Tuff clutch, (worth around $800). Not sure how much torque they can handle. It appears to be near new, but I'll take it apart to inspect. How bad an idea would it be to replace the friction disc only?

Vee_Que

They are known to be a lot better when hd. I'm sure it doesn't definitely slip at that torque, just like any other clutch it's down to use.

Dauntless

The stock units definitely do slip at around 450Nm, and are often replaced under warranty.

Vee_Que

What is being done to increase torque for you? The hd clutch would have been fitted because of the reasons you're mentioning then. So it's possibly over thinking it.

The engine is essentially stock at the moment, which means a 120kw/360Nm rating with a boost compensated 12mm pump and about 10psi. I'll initially be running the FTE CT20B at 15psi from the 1HZ.

The plan after that is to have the CT26 high flowed by Munro Racing and run it at 20-25psi with a PDI FMIC. Depending on where the stock pump maxes out at, I might send it off for a rebuild. Realistically this should achieve over 600Nm.

So little power for so much effort

Dauntless

Should be more than adequate, I'd expect it to outperform a fairly standard VDJ79.

The FTE engine has more potential for power, but it needs so much work that it isn't worth doing right now.

The 1HZ is running well enough at the moment apart from cold running and fuel economy issues, but for the price of injectors and glow plugs I could have the 1HD-T in there.

Dauntless

1HD-T with starter and bellhousing are at Cruiser Nut's place. Expecting it to be tested any day now.

Dauntless

I sense somehow that with yoda tax... that would pay for a built B230ft

Sounds like you need bottom end kit, not individual bits. So this is for the motor that you just pulled out?

Dauntless

Yeah, pretty much every gasket/seal apart from the head gasket. Unfortunately Toyota doesn't offer a kit, and I'll be going with ACL bearings as they should last longer than the factory items.

Vee_Que

Factory parts are better quality, why do you think you need them? Is the motor apart?

Dauntless

Vee_Que;137550 wroteFactory parts are better quality, why do you think you need them? Is the motor apart?

Why wouldn't I use genuine parts if they're reasonably priced? The engine is not apart, just doing what I think should be done to avoid issues later.

Vee_Que

So why use Acl? The Toyota bearings unless seized, usually are really good on an engine.

PaddlerEd

1HD-T's are notorious for doing BEB's, so the norm is to fit ACLs as they are supposed to last better, and fit them in advance and then it can be done without some extra major works.

This.

Vee_Que

Interesting.
