please! if that is so then how about this instead

 

A closer look at the holes drilled in the Star pressure plate. This reduces the surface area enough to "soften" the hit of the Kevlar for the street. They also serve as a vacuum break for quicker disengagement.

I don't feel the engineering in the design of the steel cover would be that far over that you could go drilling holes in it.

 

I'm actually pretty happy with the weight of the flywheel.

 

The blacktop flywheel on the 20v is a little lighter that this unit, not much. I think with the higher capacity and the ability the larger motor has to rotate it, it should be about right. With the torque spread of the stock cams and vvti, it wont need to achieve massive rpm change to go forwards.

the longer stroke has all the torque you need just wondering thats all as drilling holes strategically could be cheap but you are right rpm changes are minimal with what you are achieving already

Just got Neg camber roll centre adjusters in the post. :lovin:

whoa, why would you run those? you know their not good for your suspension right?

Explain.

 

I think they might be needed. Depending on what I do with front brakes. I'm using ra40 struts and am looking at different brake options. It might be a way to get a little clearance if I need it between lca and rotor.

Heli coil in the back of the motor has just been fitted.

 

Also had Danny the heli coil guru tap the threads in the block for the mounts. Not heli coiled at this stage, but with this equipment he was able to tap the entire depth of the hole.

 

When I visited my mechanic mid week he showed me a 2azfe that had been completely cooked in a rental car after the driver got a stick in the radiator. The bore blew out between cylinder 2 and 3, all the valves ruined, coils all died, manifolds warped. Pretty much a massive ʞ©$ɟ up, but it was interesting to examine how the thing failed.

Is it just firewall and gaurd clearance that is an issue Sam?

 

I have cusco camber plates, lca camber bolts, ae86 and ra40 lcas and the ncrcas. So between all that I should be able to make something work nicely.

I did more work on the bell-housing union today.

 

I examined every hole for its suitability and I ended up making a 5 bolt and 2 stud union thats perfectly strong. I was able to tap into the meaty rim of the bell-housing for the most part.

 

I have a photo with all the holes numbered around the bell-housing and some notes about doing it if anyone wants to see them.

My xt strut rotors hit the LCA but I put in xt steering arms as the ball joint hole is offset. Obvious issue is the steering arm length.

Bit of a setback. Gearbox shop didn't get the box finished. Have to wait till next year.

Bugger, no good! Ah well, great things take time. Looking forward to seeing it together - it's an impressive build so far!

Thank you.

 

I appreciate the interest lots of people have shown.

 

Speaking of setbacks, I also have a a hernia I need fixed and the cost of the operation is going to eat my ecu money plus another 3 grand on top during the holidays.

Went and did a few more small things.

 

Drilled a couple of holes in some of the larger steel plate areas of the mounts, just to shed some precious grams.

 

I also got finer emery cloth and made a jig to polish inside the inlet manifold and the inside of the oil pipe. Its like a mirror in there now. Should be nice and smooth to flow air and oil respectively. Now that I have a disc and linisher sander combo machine i was able to face the flanges on the oil pipe too, came up a treat.

be real careful about that pickup surface, its not something i would use a sander machine on.

 

love your work all the same thinga are going well.
