Funny that!

Bought valves, springs, locks, retainers, guides and seals today. Got a great deal from Fabre on the lot and it was all in stock.

Head being disassembled tomorrow and the block arrives tomorrow to begin prep too.

Very cool.

Do you have an approx completion date?

ASAP. I've dragged my feet with other pursuits in the time I've had it. It's all systems go now. I'd like to race at Sydney Jambo in March with testing prior.

Precision Gen-2 8891 and 66mm gate:

Enough assembly lube for 8 RBs:

Dirty, dirty diesel:

This is unnaturally attractive:

Almost all of this is staying out. Anyone need any airbag stuff?

All caged up:

Lots left to do:

Diesel block? (RD28)

[2rismo]

Yes.

I'm curious to see the machine work required to fit the RB head.

Any reason you are going the TH400 over a lighter option?

Will be sweet to see this car ripping huge skids again

Mother of God. Awesome, subscribed

I'll have photos of the entire process of adapting the head to the diesel block. Will also be machining up and fitting plugs for the head so there is no water near the deck at all. The block will also be filled to the deck.

TH400 was chosen because the power I expect this to make will be more than what my prefered trans will take (C4). The aftermarket support for TH400 is now so strong that they can be made unbreakable at this power level and application. They're just such a known quantity.

Yeah fair call on the Strength of the turbo 400

Going to change the stupid tall 1st gear ratio? or not a factor with this 3.4L mouse trap?

[2rismo]

Ratios in the 400 are almost identical to the C4 but with radial tyres I don't want to shock them at the hit so it won't be a problem.

[UWISSH!]

geez this will be a monster

how come you didn't just continue with the old car?

[2rismo]

The street car ran 10s pretty easy and needed a cage, GTR rear end, different suspension etc. It has since had 30psi jammed into it and it made 415kW. It will run 9s soon.

This car was offered to me as a roller with everything already done. As hard as it was to sell the red car, I have a history with this car too so it was an easy decision.

Kyle from 6Boost is making the exhaust manifold for this engine. Will fit a 5in dump without cutting up the bay and include the 6 x EGT bosses. Stoked.

Going for his 'pro-mod' manifold?

[2rismo]

This minus the V-band.

This should be amazing!

Out of curiosity what sort of rpm are you thinking of turning it to? I'm keen to know what sort of piston speeds people think are possible, especially with a 94mm stroke.

We currently turn ours to 8000rpm in our circuit car and that works out about 25m/s which is getting up there. Your engine being for drag purposes I suspect you are intending to turn it a little harder??

Manifold all tacked up and ready to weld. 6Boost really don't mess around!
