Thanks Ben,

It's 42mm OD X 3mm wall

[allpaw4]

Nice. That ain't gonna move, especially given the shortness of the tubing.

[JDWhiteWRX]

The engine mounts are finished!

 

Here is the process.

 

Started by notching some tube to join the engine plates to the shackle mounts. 

 

I tacked the position on the car and then removed them to weld the main part of the tube that joins the plate on the bench.

 

 

 

Back on the car and some more tack welds to get the final position.

 

 

The whole time I am checking the alignment of the motor with the diff using a laser pointer.

 

 

After that I had to press the poly bushings back out so I could finish all the welding and then gave them a coat of paint.

 

 

After they were dry I pressed the bushings back in and installed them on the car.

 

 

 

 

 

It's 51mm behind the original firewall as per the WTAC pro-am rules.

 

 

The crossmember fits around the dry sump pan perfectly

 

 

This last photo shows how nothing sits below the frame rails, the lowest point is actually the trans adapter plate and I shaved about 10mm off that to get everything as low as possible.

 

 

I have actually made a pretty good start on the transmission mount but I'll save that for another update.

Very nicely done!

 

I love how there is a ton of room between the engine block and the inboard struts. Are exhaust manifolds free under the rules? If so, that amount of space will be handy!

[allpaw4]

Wow. Keep the updates coming! This is epic. I find myself coming back and checking this thread every day or two... Some pretty amazing work!

Looks like it's all coming together.

Cheers,
Ben

Getting very exciting now with the main mechanicals going in! Still loads to do.

Can the radiator be mounted in the rear, or is there no advantage to that in this application? I guess the best cooling it’ll get is behind a fat intercooler. And yes, correct fat term used

Keep up the good work. You make my efforts look like child’s play in the sandpit!

Yes I plan to mount the turbo as low as possible to benefit the COG and build my own manifold to suit.

Thanks mate.

Yes a lot to go, probably not even half way yet realistically.

 

Rear mount radiator is more a drift car thing, not really ideal for aerodynamics. There is plenty of room out front for a properly ducted radiator/intercooler combo.

I worked on the transmission mounts yesterday but ran out of time before finishing them. I got a fair bit done so here is the progress so far.

 

I didn't want anything below the frame rails as my flat bottom will be bolted up hard against it. So the mount is to stay up inside the tunnel. This is easy with a track car because I can access the bolts from inside the car.

 

I start by reinforcing the ultra thin sheet metal that the tunnel is made from with some additional 1.6mm sheet to tie into that existing reinforcing bracket.

 

 

My mig welding still sucks but it will hold, penetration looks good on the other side, its just not pretty. I use a 3mm plate over the top of the reinforced tunnel.

 

 

I have a matching 3mm plate inside the tunnel.

 

 

 

I've welded the nuts to the plate, makes it simple to install plus one of them will be inside the tube so I won't be able to get a spanner on it later.

 

 

Then its just a length of 1.75" roll cage tube to span the gap, very light and very stiff.

 

 

I welded the majority of it lying on my back under the car, it came out nice.

 

 

So this is as far as I got. All I need to do now is extend some plate out to those poly mounts and add some gussets and its done.

 

[RX25SE]

Neat!

[allpaw4]

Wow. That's cool. Keep it up man!

Cheers,
Ben

The transmission mount is now finished so the engine and trans are 100% in the chassis.

 

Here is what it took to finish it off.

 

Start by cutting out some 5mm thick flat bar and drilling a hole for the trans mounts.

 

 

Get them in position resting against the tube, make sure everything is lined up with the laser pointer.

 

 

Put a few tack welds on them to hold the position then remove the crossmember for welding.

 

 

Make some gussets from 3mm steel using CAD

 

 

Drill a couple of holes to add lightness

 

 

Weld it all together

 

 

Some paint

 

 

and reinstall back on the car. The total weight was only 1.5kg

Nice work! Looking great!

Keen to see more of this beast!

Cheers,

Nicely done!

My KPower Industries RWD intake manifold arrived yesterday, it's a really nice looking piece and the price was much better than other options on the market.

 

I also added a little custom touch with some wrinkle red paint to match the valve cover.

My dry sump kit arrived today from AT Power ordered via my local distributor which is Manon Racing Products in New Zealand. 

It's their Honda belt driven dry sump kit minus the machined billet aluminium oil pan since I fabricated my own from the OEM pan to save some money.

 

I have been waiting on this kit so I can get the steering rack mounted. The steering rack will sit as close as possible to the crank pulley in front of the engine but the belt drive pulley for the dry sump oil pump also sits on the front of the crank pulley so I couldn't mount the steering rack until I knew how far out it protrudes.

What Barbs said.

It’s all coming together bit by bit. I wish my projects moved this quickly!

Keep up the good effort, don’t get distracted with the upcoming snow season

Thanks for the update with pics!

Cheers

[RX25SE]

Looking good as usual. Keep the updates coming!

So is that pump 2 scavenge and one pressure?

Thanks mate, yes 2 scavenge stages sucking from the pan I made.

 

I just have to make my own bracket to attach it to the engine block and run all the lines. I haven't decided if I will buy or build the oil tank yet.

[El_Freddo]

No brainer with your skills! Build one, and one that’s VERY custom for “good measure”

Either way, can’t wait to see what you come up with.

Cheers
