DIrtyTorque's odd corner.

Post by dirtytorque on Sun Oct 19, 2008 10:44 am

Hello
Base car.

1992 Corrdo g60 in Flash( Lol) red.

[You must be registered and logged in to see this image.]

My ulitmate aim is a ghetto 2.0 litre 16vg60 build running MS.
I'm just going to add little bits each day to this thread.It will be nice to have it documented somewhere,like a diary.

MS setup:
I am running the Vanilla MS2 code.Running fuel and spark.MS is triggered off the stock digifant Hall sender trigger and uses the Onboard vb921 to fire the standard g60 coil.
No TPS,using MAPdot acceleration enrichment.Acceleration and throttle response is fine.More consistent than with Digifant.
ISV is controlled onboard too.
No closed loop idle control att,the isv is just used to introduce extra air on cold starting.
Idle is very steady.You wouldn't know it wasn't digifant.
I am currently bedding in MS on my 8v 1.8 g60.I am getting to the stage where i am happy with it.

2000g6016v Engine Build:


Base engine Audi 80 3a "Bubble block" chosen as it has the same deck height as the kr block.I am using a late Kr head as found on the 6a engines.
[You must be registered and logged in to see this image.]

As I am using an 8v bottom end the compression ratio drops by about one point as the kr head has a combustion chamber about 13cc's larger than the audi 80 head.
With the valve pockets that had to be cut to stop interfearance i should be at about 8.0:1 which gives me plenty of room for maneuver.

target this month.
Finish the tensioner setup.

Thanks for reading.
Lets see if it blows.
More soon.

All you need to know is they spin really really fast and add lots of power.

What's the Vanilla MS2 code dude? Your MS hardware looks like it has a few extra internal mods?

By vanilla I just mean I am running the stock MS2 code.
Not the MSextra code.

The only mods I am running are the TPIC120/121/122 pwm mod for the bosch ISV.
I have replaced the ignition driver chip once(during fault finding when I was trying to start the car,It wasn't the issue.Rolling Eyes) and so that may be the other thing your seeing that looks foreign?!!

I just went for a drive to get some current logs to show you guys but the laptop died.
I think I need a new one. No

nah,my mind has been elsewhere,checking out a few things on my megasquirt config and changing all my engine mounts which I have finished today.
Just need to check if it has resolved my gear change problem under sudden acceleration.

EDIT:

which it didn't.it was the pesky circlip.
Always check the simple things 1st Lol.
New mounts are a good investment though.Mine were worn I used to get a heavy bang on hard acceleration.

New tensioner setup incorporating an idler I found on a vauxhall vectra

It has a lip on the outside edge but ot the inside.Not ideal but I am going to run with it for now.
[You must be registered and logged in to see this image.]

As you can see I need to get 6mm shaved from the crank v belt pulley for proper alignment due to the wider 16v crank sprocket.
[You must be registered and logged in to see this image.]

As long as the pulleys align nicely there shouldn't be any belt walk.
I hope. Smile

I'm getting there I think now.I'll get the crank pulley machined tomorrow me'thinks.
Then I'll start building up the bottom end.
stick it in the car start it tune it and flog it to death.

that is all.

ok i have been re checking my valve clearance this afternoon.Originally i was told that you should be able to turn the engine over with the head on the block with no gasket and you should get no interferance.
It was while doing this test that i concluded that I needed valve reliefs.
However with my new valve reliefs the engine still does not spin without the head gasket.
On closer inspection the cam lobes havn't started to effect the hydralic buckets yet anyway so it is as if the pistons themselves are touching the head!??????

With a headgasket in place I have no problems and can spin the engine over fine.
Hmmm..
Tomorrow I am going to put the original 8v audi head on there without a head gasket and see if I can turn it over.

Have you got the timing belt fitted? Do the camshafts spin ok? Have you got the head bolted down?

Hmmm. You tried sitting the head on the block with some pistons at tdc to see if it will sit flush?

The compression lump that is present on the 8v pistons will be proud of the block by some 0.7 mm and will contact the 8v head. With the head gasket in place it will not. The valve reliefs are to prevent contact due valve float as I now understand. I would of had the 8v CR lump milled from the piston but then that's just me. I also think it was me who suggested turning the engine over without the gasket present to see if the valves contacted the pistons. But I forgot about the CR lump. Embarassed Sorry!

I think I was also told that by the guy who does my engine work so no foul.
By the sounds of it it is probably best that those vale reliefs are there.

I'll see how much it will be to get the CR lump milled off.
I remeber you moaning about getting them removed b4.


Good work

So, the 16v is going in this weekend then?

Are you sticking with the dizzy or are you going toothed wheel and coilpack?
