Yes of course it is a staged testing campaign. All initial tests will be with our current GTX35 set-up.

Once that is maxed we will try one of the new 37's..

Do you know the weight penalty with the billet block? What will you use as a rev limit with that 83mm crank?

Will know exact weight limit in a couple weeks when we can weigh one of each at same level of completion..

Rev limit for 83mm crank is exactly the same as with std block. Very dependent on supporting mods and rod ratio chosen.. We generally limit them to around 8900-9000

Thought as much,
Still can't get my brain around the idea of a 1000hp 4 cyl ej motor in a time attack car, if you guys pull it off there's going to be jaws dropping around the world that's for sure.

Hope to do final assembly of first proto-type next week. Probably 3 weeks before we run it though.

Go ahead and front me one of these blocks, I'll pull the wastegate line on the 6766, then we will see what this block can handle.

I'm sure it shouldn't have a problem with a few 65+psi spikes

Because the cars don't handle well enough to compete on the track with all that weight forward of the front axel.

Front me some cash and the block is yours to abuse as you like.

As good as the block's design is, addressing the many weaknesses in the OEM cast item, I think we all know that accurate tuning and adequate boost control will still be required.

...you've popped a sleeve on a standard H6?

there's around a $10,000 difference between this engine and an H6 swap. despite the few kg's more in weight there's no way you couldn't spend $10,000 somewhere else on the car and make up the difference. this is really only an "infinite budget" part.

That's what I mean by full span main cradles. It's also pinned and more main case bolts. Have a look at how the OEM main cradles swing in the breeze and then you'll understand why there is movement and nasty irregular wear on your main bearings.

That won't be happening here.


I have a few questions regarding engine lubrication. Will this be running a standard wet sump and oil pump or will it be dry sumped? If not dry sumped with main bearing cradles extending all the way down, where will the windage tray and/or oil pump pick up tube connect to? As I do not see the provisioning on the bottom of the block, unless the machining is not complete in the posted picture. Thanks

Yes this product can be set up for std sump and pick up.

Initially we are testing one of each. Although we already know that for any circuit racing, you really need a dry sump set-up to guarantee accurate oiling. We use and recommend the Daily EJ Dry Sump kit.

We do already have a customer car that will be running Cosworth dry sump set-up, which is like a hybrid system combining a Cosworth vacuum/scavenge pump, with the OEM style oil pressure pump. So I guess we can accommodate all needs here. But we're only doing this one like this because the customer already had the cossie system.

Having said all that we strongly recommend the Daily system for all customer engines as we know it works great and has facility to scavenge from the heads as well as the sump, which is a big bonus on circuit driven applications.

Yes H-6's pop sleaves also.

But hey it's horses for courses. This is not for everybody. Just like H-6 transplant is not for everybody..

How about a challenge, can you build a H-6, put it in a GDB and take one of these babies down at the circuit? I'll allow you an infinite budget.

See you in October

I thought you guys had already gotten one of these to Ben? Although I haven't gotten an update from him on the WTAC car in a while...?

Edit: Just looked to see where he tagged me in it on the face machine, circa March 2012.
