Awesome tubular crossmember!
Little spendy, but less than I thought.

and only $99 shipping! That really isn't a bad deal at all.

Don't forget the oversize fee!

Not too bad, however I can get one for around that price, with a vin, and lots of other body panels!

That looks amazing. How did you get the tube ends curved and angled to mate so perfectly? Fly cutter?

I used the cheapest woodward fab tubing notcher and decent quality hole saws. Milwaukee hole saws have worked good.

It’s been awhile since my last update. I dropped my block off to MAP to be machined for the new 2.2L HD pistons and one thing led to another and MAP completed the entire long block for me! Alex did a great job measuring everything on the motor. I can’t say enough how happy I am with the precision measurement, over all quality and focus on details that Alex, Eric and the other MAP members have. I don’t trust too many people or shops, as I do everything that I can myself, but I can say with confidence that MAP’s engine program is world class.

The engine is an:
• Eagle 94mm 6-bolt crank
• 9.75:1 Wiesco HD2 pistons
• 1/2” head studs
• ¾ filled block
• R&R 153mm aluminum rods
• Stage 5 MAP cylinder head, with Inconel exhaust valves and the deck surface has been stinted.
• No O-rings, Felpro Permatorque gasket
• GSC S3 cams
• Kiggley HLA & 12 tooth trigger crank sensor
• 200W heater in the oil pan with an oil temperature sensor.

The motor is in the car now and all ready to be started.

This weekend I finished up the fabrication on the 3000Gt rearend. It’s huge compared to the factory 1G unit. My Pro Stage 5 axles will be custom machined for the new rear. The last rear end only lasted 5 passes. I kept breaking the spider gears and I didn’t want to weld the diff and have ring and pinion failures.

The car is almost down 100lbs too!

I want to break my cage certification. Sub 8.50’s here I come!!!!

What are the measurements on the 3kgt rear end compared to a 1g rear end? That rear end should hold a lot more better I would think.

Not exactly sure on the measurements, its way bigger with larger everything! I shouldn't have any issues.

Looks great mark !!

Amazing build.
Can't wait to see you beat that cage cert.

Another 100 pounds?!?!?! You crazy son!

I'll give a +1 to MAP's engine building program; Alex built both of the 2.0's for my X and I've had nothing but good luck and solid performance from them.

I love how you build most all your parts Mark. I wish I was more handy in the fabrication department to do that. It makes it that much more satisfying when you run what you do.

Re: Mark's 1G Winter Projects
 
Forgot to ask, how are you bolting up the rear section of the driveshaft? Do the 3kgt and 1g have the same pilot and mounting bolt on the pinion flange?

The pinion flange pilot is the same size, so it self-aligns. The bolt pattern on the flanges are different and the rear end needs another set of holes to adapt to the 1G driveshaft flange.

The mounting of the rear end is where it gets difficult. No bolt holes line up and you basically start over with the fabrication of the mounting. The rearend needs to be modified so that it fits the smaller 1G subframe. I ended up cutting two of the mounting points on the nose of the rearend because they protruded out too far and were interfering with the subframe. There a total of three points on each side, so I wasn’t too worried that I’m not using all the points.

I'm not familiar with 'stinting' the deck surface, can you explain or provide pictures?

what's the reason for the oil heater? Reduce warmup time before runs?

Mark Leasure 04-10-2015 09:21 PM
Re: Mark's 1G Winter Projects
 
Stinting reinforces the deck surface of the head in spots where head gaskets tend to fail. It is done by milling holes in the deck surface at the weak points around the deck. Then pressing in solid aluminum rod in the holes, the rod is tig welded into the head. There are two locations per cylinder. It was MAP's recommendation, as they had successful experience with it.
