Out with the old and in with the new. It took 4 straight hours of grinding to get the frame rails smooth again. I now need to mount the steering rack so I can make the new engine mount brackets.

Mad fuking skills man.

Another long weekend but i got the engine mounts done and steering done.

Is there much of the original truck left?

Yea... The blue parts

Finally got a hold of Rimac to get a replacement scale for my spring compressor. They said they are no longer available, so I made my own with a metal adhesive backed tape and a hacksaw blade. The head is back from the machine shop so it won't be long now until its running. finished drilling all the holes and pressing the in all the pins in the oil holes of all the buckets with my home made pliers. I put the buckets in the lathe after and turned the pins .015" below the surface. The lifter shims are only in .05mm increments so there will be a lot off polishing/sanding the shims to get all the valve clearances perfect. Oddly enough with nothing being available for these engines Gates still makes racing timing belts for them.

I was so surprised that they are available and reasonably priced. no one makes anything for this engine.

OH ok that make sense

All the valve clearances are finally set. What a pain in the ass. They are in .05mm increments which is .002". The specs for the intake are .008"-.009" so I had to sand them down. Those tiny little pucks are so hard it took about half an hour each to take off .001" using the 250 grit diamond honing stone.

I forgot my Playdoh to check piston to valve clearance. I'll hopefully remember it tomorrow to verify everything and start assembling the engine.

Wow that looks like a lot of work, I see somebody drinks Space Dust IPA bier.

fastivab6tg25mr · « **Reply #312 on:** December 29, 2022, 10:32:03 AM »

Space Dust is the best. And yes, so much work. I remembered my Play-Doh and was able to check valve clearance. I have 1mm on the intake and .060" interference on the exhaust. I'm going over options as to how to move forward. Either I'm gonna try to get a 3mm thick head gasket which seems way too thick or contact Wiseco to see if the dome thickness is enough to cut the valve reliefs

92CXyD · « **Reply #313 on:** December 31, 2022, 05:56:56 PM »

Good thing you checked

fastivab6tg25mr · « **Reply #314 on:** January 05, 2023, 10:55:15 AM »

Verified there's plenty of room for machining the pockets deeper from Wiseco. I ordered an angle plate for my Bridgeport mill that will be here Monday. Can't wait to actually finish this engine.

fastivab6tg25mr · « **Reply #315 on:** January 08, 2023, 01:20:07 AM »

Angle plate got here early. Made some soft jaws by annealing some copper plumbing couplers so my toe clamps cant mar the pistons. Had to open the slots in the base cause they're 12mm and not 1/2". Broke a tap making new T-slot nuts out of some grade 10.9 bolts. Luckily the tap broke high enough to grind it back and tap a second one. Got a test piston cut. Gonna clamp up the Wisecos tomorrow and hopefully they come out as nice.

Finished machining the pistons and started the final assembly. More issues with the head I bought, they only cut one gear to make it adjustable. Luckily, I have a lathe at work and was able to cut it but it's still very frustrating. With the head torqued I reconfirmed that it is a non-interference engine. I needed to know that the pistons 100% can't touch the valves just in case something goes wrong. I made a new CAS extender to fit the FE5A camshaft. Had to reduce the diameter of the offset wing piece without touching the wings which was pretty sketchy operation then machined down a lug bolt to make up the extra 30mm pin to pin distance.

Nice work I like look of those gears

Pulled the wrap off to re-rap it and found my #1 runner split in half. welded it back together and found the exhaust flange badly warped. No machine shops would put it on their belt grinder so I spent 4 hours with a surface plate and 80 grit sandpaper to get it to within .005" of flatness.

Hopefully this is the last finishing touches on my mustang 2 front end. Turns out my upper control arm height was an inch high, and the lower edge of my cross member was an inch low. Proper suspension geometry and ground clearance has been restored. I just need to do more clean up, shoot some paint on it so it doesn't rust and finish the final touches on the motor so I can drop it in.

92CXyD · « **Reply #321 on:** January 31, 2023, 10:38:06 AM »

Nice!

What size WG you using?

Looks like a 44m?

fastivab6tg25mr · « **Reply #322 on:** January 31, 2023, 10:39:33 AM »

It's an MVS 38mm

Congrats, the contrast of the vid, make the coil packs look like they aren't even connected.... almost like wireless

They're bluetooth, it's the same technology that the SEMA trucks use for their front drive shafts lol

Tying up all the loose ends. Condenser is mounted, oversized slave from a 86 4Runner SR5 installed. There is a massive improvement going to a 13/16 master vs the stock 3/4 master. Brake hydraulics are all finished and leak free. I've been driving it for the last few days with my shop floor alignment using a toe bar, tape measure, and a digital angle finder to set camber. I need to get 500 miles on it to break it in before final tuning.

Had to do a double take, then blow up the 1st hood picture, thought you had the vent openings towards the front and not the other way.

Where did you get the vents?

What calipers are you using?

fastivab6tg25mr · « **Reply #329 on:** February 15, 2023, 08:32:31 PM »

the vents are from rodlouvers.com front brakes are S10 metric calipers on mustang 2 adapters to run Grenada 11" rotors
