Put on the polished water pump, thermostat and housing, romac balancer and ps pulley, oil filter.
Looks tougher. Getting the exhaust manifold and turbo housing ceramic coated.
Plenum was going to be finished Saturday but the bloody press was shitting itself against the rams when they were being pressed and the die needs to be slightly machined some more as it's about a milimeter off.... I wasn't too fussed but the fabricator is so fingers crossed until weekend.
Engine is about ready to be dumped in car, stated up NA and run in for a couple of thousand kays.
After that all the boost gear on.
Who are you get the polishing work done by?
an easy fix is get a mate to drive in front of you at 60 then 80 then 100 and mark in on your speedo with some liquid paper.
Ok, finally, the plenum is nearing completion.
Was a mission to get it out today all in one day pretty much. The pieces were individually finished prior hand but the fabricator is a one man show and with race season passing through he really got smashed by a lot people that would come unannounced.
They took up a lot of time and the small workshop upgrades he had to make and the custom making of presses, dies etc so he can do the runners properly all took time in his busy schedule.
I was pressing for this to be finished asap so this saw him go off his measurements and basically piece it all together yesterday and today and yet again he ran into another problem with the press jack shitting itself.
Anyway, deadlines were promised and deadlines were not met but here are some progress shots anyway.
Shot of base plate inside plenum with trumpets.
They're about 2-2.5 inch trumpets from memory and taper down into the runner pipe. He had to press out and flare the runner pipes to match the trumpets. This is also beneficial in his race car applications with creating a little air speed.
Another view of trumpets
And here with the plenum begining to be formed and rolled.
This is the the whole plenum all tacked up and measured up in a dummy xe.
Initially we thought we somehow made a mistake with the measurements as it was merely a centimeter off the shock tower and fouled against the power steering pump.
We then realized that the measurements we took were true horizontal and not perpendicular to the engine.
When he made the plenum he assumed that the head/engine would also be perpendicular to the ground but it's on a slight angle.
In this pic,
The throttle body will be positioned differently ie with the gas feed on the side and throttle cable bracket fabbed underneath.
I made a decision to get the hose bung and pop off plate welded to the inside base plate side of the plenum so that hoses can be mounted easier and removed easier and springs in pop off plate can be changed much easier than making it look all pretty and having it hide underneath but be highly impractical being hard to get too with little room there.
It's just you
Fabricator came around early in the morning as he got up at 6 am to sort it out.
He cut the angle properly and it came up the goods. Plenty of clearance as it was intended from the start once the angle was correct.
This is the raw finish for a mate.
Mine will come later as he needs to polish up every ram/runner individually, the plenum and other bits.
Looks sick in person too!
Why not just shim the passenger engine mount? I don't think anything on the driver's side would be so tight?
nice, that must have cost you a kidney or two.
Hr under construction
Nah, just a brush.
That one is the template. I'm getting mine done completely polished.
Hopefully can drop the engine in this weekend. Will be NA and run in that way for first couple of thousand before I put the gear on.
yep that's me.
Thanks heaps for the offer. Will let you know if I run into issues.
Yea cool as, between LTD351T and I we can get that LPG 250T humming!!!
best advice so far is avoid those shitty 90deg plastic fittings that come from GRA on the vapour line. get some nice 316 Stainless threaded fittings and smooth bore bends and get your fab mate to weld zem up.
Got a t04 split pulse rear housing for the gt35r turbo
Previously was original internal gated t3 flange from xr6 turbo.
This is amazingly impressive.
Computer half went in today. Rest of it and Ice ignition tomorrow hopefully. Fingers crossed rain holds out.
Putting it all in and running on the old NA engine first, sort out any bugs over the week. If all cool, next weekend drop the new engine in and run that in for a couple of weeks.
Then Exhaust, intercooler, turbo gear, plenum etc all go on..... perhaps in time for the supernats.
The Megasquirt computer is pretty much built and ready to go. We tried to get it in on the weekend on to the original engine along with the Ice ignition so as to teeth out issues on the old engine and not the new one but the MS was not speaking with the ICE and wasn't triggering, ie no spark. So we put all the old stuff back on.
A few words with Michael from Ice and we've figured it out so hopefully tomorrow after work the mega squirt computer and the ICE ignition will go in. Rephrase - Drew has figured it out.
If all good after a week of bugging out, tuning and driving will drop the new engine in after tidying up the bay a little and run it in NA.
Once that's done, get the exhaust fabbed, dump fabber, IC piping and extra gas converter as well as lines.
Some highlights of the day .... well low lights too
Figuring out ICE wiring prior to fitting
ECU being tested with tester board.
DREW putting final touches on ECU
Stayed up to 430am last night/morning and the results are like this for first start up
and then this for a slight tweak here and there running only on LPG
As i said, 430am and we had enough.
It hated petrol and didn't want to idle or run right. Something isn't right obviously and we both weren't fresh enough to keep trying.
On LPG we got it idling smooth, I took it for a drive and for the first 2000 revs I was almost gobsmacked! It felt like a BA engine, very... very alive but then backfired after 2K and ran like ****. Shot a backfire and I backed off
Back to tuning a little and backed off the advance and although it ran, it was very sluggy and felt as if there was no advance at all.
I could not be stuffed and didn't want to put a hole in the piston so we left it at that and I will plug in the lappy tonight to have a fresher look.
Some highlights of the night.
Firstly needed a small piece of pipe to put the air temp sensor in. At 8-9 pm where was I going to get it from? My fabricator of course lol!
All I wanted was a piece of 3 inch pipe 4 inches long and I'd do the rest. I called him up and asked and he said sure, come around.
Went there and he asked what it was for and then I told him. Being a perfectionist, he didn't want to give it to me because he knew I'd just put a hole in it and silastic it.... after all, it's only in there for a week or two.
So he drills a hole, gets a boss, taps the thread, welds it on and then smiles.
Couldn't ask for more at that time of night but talk about over-engineering lol. Top bloke and top work!
On the car
pairing up and sectioning off wires.
All in the car. Some wires/looms merely coiled up and zip tied to a section for temporary measure until we rip engine out and put new one in. and then cut everything to length to suit and hide as much as possible
Gotta thank my mate Drew for his hard work and patience and we're half way there I reckon.
Just a good tune now and let it go for a week.
Great project but I had to delete your sig.. That isn't how we roll over here bud.
Sorry... what did I have, I can't even remember.
Issues still with ECU timing. It's way retarded as the exhaust was glowing red and it's a slug to drive.
Will remove the wire to dizzy from ECU, take timing and set it to 10-15 degree advance incase in all the moving around we stuffed the base timing.
Then plug ECU back in and check at idle what timing is showing.
If it is out then there is something up with the ECU wiring or if it runs fine without the ECU again, something is wrong with the ECU wiring.
