Chikinhed's Mini Build

[chikinhed]

I like how I can order a part from England on a Sunday and I receive it on Tuesday. I’ve wanted these for a long time to deal with the issue of engine mounts that like to tear. Vibra-Technics claims they are ‘completely failsafe’. Too bad it will only fit on the drivers side.

if you switch to top-mount you can run both

[chikinhed]

Going top mount just exchanges these issues for those issues imho, but your right then I could use both.

I’ve made some progress on my engine build. The piston, rods and crank are in. Ring end gaps adjusted and bearing clearances checked. I’ve finally modified the S54 oil pump to be high volume. End clearance checked, pump assembled and installed.

Can you take a picture of the oil pump chain tensioner and explain the mod and the part source — Euro S52?

[NY98M3]

What ATI damper is that? Tensioner looks different too

[chikinhed]

The oil pump chain tensioner is from the S54 which is the same as the euro one. The ATI damper is from VAC. I bought that one because I wanted to keep the AC.

I was on a roll tonight until I discovered that I have an M52 head gasket instead of an S52 head gasket.

At least the block is back in the car and the transmission is all bolted up.

Lookin good!

[beeasy]

What rpm are you spinning in this?

[chikinhed]

7200 rpm....... for now.

The goal has been longevity so far.

[chikinhed]

I gave my car head tonight.





And some new exhaust studs.



I’m using the 11 mm ARP L19 head studs again but I’m going with 85 lbft instead of the 105 lbft that I did last time. All the head studs are torqued and I’ll recheck them all tomorrow.

I like that I’m slowly regaining space back in my garage as the parts go back on.

[chikinhed]

I didn’t notice that the head was missing a threaded hole that I use for the Autometer coolant temp gauge until after the head was installed. Luckily there was still enough room to drill and tap the head. It’s the fitting between the two coolant temp sensors.

[chikinhed]

Today I finished up installing everything on the intake side of the engine, did some cleaning up at the Steed wastegate port to try to improve flow out the EWG then installed it. It’s starting to look like an engine again.

[Mklock]

Always found it easier to set cams while engine was outside the car. Any reason why you waited after block was back in?

[chikinhed]

It’s just easier to get the block in.

The initial setting of the cams will be with the blocks. I’ll heat cycle it, then take the cams back out to retorque the head and then degree the cams to my favorite settings.

Great progress! Are you the one who changed from a turbosmart EWG to a Tial because the turbo smarts are inadequate on the steeds? Just wondering because im rebuilding everything also.

I did switch from the Turbosmart to the Tial. You need to notch the Tial valve seat bottom or trim the divider on the Steed. I notched the valve seat bottom and haven’t had any issues.

Ok, got it. What were the symptoms with the turbosmart that led you to switch?

Not as able to control the boost as the Tial.

[chikinhed]

Man, that EFR 9180 on the Steed 2.0 is a tight bitch to install and connect everything around it but it’s back on. I had to stop, maybe I’ll get more time later this week to finish the under car stuff, then onto the cams.

[chikinhed]

I just found a great article on how to set up the Turbosmart IWG75 that explains the set up procedure way better than the instructions that came with it. I had been experimenting trying to troubleshoot my boost control issues and since I still have access to the IWG75 (barely) I think I’ll finally resolve the issues.

Anymore info on the water injection pre compressor. Is that mounted to the silicon coupling?

[chikinhed]

The WI nozzle holder just sits in the coupler up against the turbo.

I’ve dressed the two supports so that they are symmetrical airfoil in shape, chamfered the the nozzle hole on the spray side for clearance to the spray cone pattern and TIG welded four raised bumps around the outer circumference to help stabilize it in the coupler. The turbo inlet tube has a short piece of 1/4” tubing welded though the side of the bend at an angle that the WI 4 mm nylon tubing passes through to prevent chafing and provide a easy way to seal up the potential unfiltered air leak.

[chikinhed]

Last night I got the turbo intake, driveshaft, down pipe and exhaust all installed. I also installed the cams and trays but the cams still need to be timed.

I’m going to see if I can make a tool that will allow me to torque the head studs with the cams and trays installed. Fingers crossed.
