Engine builder likely has started my engine. Dropped in on Tuesday or Monday? retired so it doesnt matter lol to give him a painted and clean sump. Also emailed him heaps of info from forums.

He is a thinker- thats what I like. He expressed how he will "investigate" various avenues re: pistons including the EJ20 type etc.

With the 16/56 cam he cant go too high on compression though.

Engine builder has been delayed however initial observations revealed that number one cylinder has "dropped" a ring. Some head damage but will clean up ok. more info to come.

The auto looks awesome mate! Time to buy some cloths to keep that thing spit polished

Your engine will come in time... Just have to wait

It's nice to install a fully gasketted transaxle painted and adjusted. So have been cleaning up all the electrics. Tweety is wired to charge the camper battery with 100amp fuses and solonoid etc so there were wires all over. Remounted all of that.

Yesterday mounted the KNF cone filter finally out of the way on a proper mount. Extra structural items to cater for the weight of the 50kgm roof, the trike wasnt designed for. Although I had an engineer build the roof there have been gremlins in the design for the trike to take the weight. Now I'll have no issues there.

The engine builder is to clean the outside of the engine and am going to paint it clear. The rocker covers have been sent away to be coppered and double chromed. Should look spick! The adapter carbie to SPFI manifold is being donw this week by "portable machine tool Australia" a fellow trike mat eof mine in Carrum Downs. That will have the carbie fully level and not on an angle. and with dizzy clearance!!.

Sounds like it's all coming along well!

Can't wait to see Tweety back on the road!

No Jonno, havent got the donk back yet, but, in the meantime I thought I'd check my rear brakes.

The front single Harley caliper was replaced last year.

The four rear calipers (two each wheel) had new pads put in last year by a 'reputable' brake 'specialist ' last year also. They are near Epping plaze north of Melbourne.

First problem- a circlip was missing on one caliper. This circlip retains a bolt inside the piston allowing the piston to retract. Without it the piston places more pressure on the pads and hence the disk.

2/ the lower caliper had the pads on upside down. Means that the corner steel of the pads wouldnt penetrate the steel sliding frame. Results in the pads being jammed and placing pressure on the disk.

3/ A bolt holding the caliper onto the bracket didnt have a washer. Result...the end of the bolt was scraping on the disk.

The other wheel calipers were perfect.

I wont take it back. Not worth it. But I will from now on do it all myself. I'm tired of booking my vehicles in with young guys doing the work and not someone with maturity and knowledge. Or I'll take it to Coolomon motors near Wagga, a trike owner "buck" who knows how to take things apart and put them together...

Here are pics of the SPFI and adapter. Was nearly finished. Will be sent tot the engine builder so he can attach to the donk.

That is just what forums are for - sharing that sort of porn!

A bit of thought go into that . or copy something from USMB?

Great bit of work for Tweety.
Comparing it to other adapters, would it be better to polish the steps out, to allow smooth flow?

Tweety · Post by **Tweety** » Thu Sep 04, 2014 8:54 pm

Hi Steptoe and Tambox

I got the impression he hadnt quite finished it off before it was to be sent to the builder. So maybe smoothing out the steps was planned.

Something similar might be on USMB but I didnt see it. Purely my own set up this one Jonno. Carbie will be nice and level. Dont know how much space there is extra but must be double the stock ea81 intake hole.

steptoe · Post by **steptoe** » Thu Sep 04, 2014 10:21 pm

neah, the steps might help air get rippin' and and the right sort of turbulence. Doubt you could see or feel, or measure any performance difference between the steps or polished.

That's a sweet looking adaptor there mate!

Will there be enough room between the carb and the dizzy? I don't know if there will or won't, I'm just asking the question more than anything!

This will be one very interesting setup once it's complete mate - I can't wait to see it!!

Cheers

Yes, plenty of room. See the first pic of the adapter. Notice the thermostat housing top left. So the pick is looking from the alternater side. My friend Peter was instructed to machine the adapter so the carbie sits towards the ring gear end so as not to get in the way of the dizzy and that small chrome alternator that sits directly above the water pump rather than way out there.

Chroming is the go to. The alt, rocker covers, maybe coil cover etc.

Is there enough room there for the butterfly's to open completely?

the steps will make for more turbulence which will help mix the fuel and air better

Turbulence in the right amount in the right place is fine, the length and rough finish inside Subaru manifold will allow plenty of time and tubulance for the air and fuel to mix.
A problem you may get with the steps, is relative to which way the butterflies open over them and how close they get. These can cause flow problems with the way the carburettor works.
This is possibly only a minor issue, but out of all the motors fitted with carburettors I have seen, never seen a "properly set up" one, with steps under the carbie.
Could be a new concept:rolleyes:

Went and had a look at the new 38. The butterflies open (both) from the inside. eg both butterflies appear at the bottom of the carbie from the inside so they wont be hindered from any outside rim of the adapter.

I wont know until I see the adapter if my friend smoothed out the steps. At this stage I'm not concerned but its a good discussion.

EYE CANDY.

Update, engine is at a location where its being balanced.

There was a revelation. One side of the block the piston was 11 thou from the top. The other side was 30 thou. 19 thou difference.

He has asked for a can of clear engine paint so he can paint it after bead blasting apparently. makes it easier he says.

The new engine will have a compression ratio of 9.47 to one.

And it will have these.

Ooo ... shiny bits ...

Yep painting the engine block in clear will help with keeping it clean & maintain the 'fresh' Aluminium look ...

Cheers, Bantum ...

I take it the halves have been milled so the difference is gone

Nice bling I can't wait to see this engine and transmission in place.
