I fired up the new engine on Monday and ran in the cam the head temp stabilised at 141 degrees C at number 4 spark plug, I have to get a muffler fitted before I can start tuning it up, some of the specs are
Type 4 case
Bore 105mm
Fat crank Stroke 80mm
Swept volume 2.77 litres
Inlet valves 44mm
Outlet valves 40mm
Match ported and polished
Scat C35 cam
Lifters Lube a Lobe
Swivel Rocker feet
Fly wheel 1800 lightened
Carbies two, two barrel Dellorto 48mm DRLA's with 40mm Venturis
BAS Porsche cooling kit
Distributor SDVA with Pertronix ignitor with MSD 6al2 digital Module
Spark plugs D6EA and 8mm HT leads
Rotor button has resistor remove as per MSD directions
I have a stinger for it for fun, it needs a 3 bolt mount and also needs the bung fitted for the Lambda sensor which will all be done when I get the muffler fitted.
Looking foward to some fun shortly

You have already seen it but here it is again

You can tell the difference because there is no stock oil cooler or filter, about the only thing I have to do now is make up some skirts to go around the spark plug caps and sika flex them in place.

This is a complete motor I just unbolt one and put in the other there is no swapping of parts. As soon as someone comes around thats strong enough I will put my 2.1 litre on my 1800 bell housing engine stand and I will be able to run it at will so there no chance of it seizing on the shelf.

Hey Tratty what is your oil filter setup as I have same exhaust just a bit smaller and i'm having trouble finding a remote oil filter setup to fit?

It goes first through a Z 9 oil filter mounted my to engine cage just low and to the left of the left hand carby, then to a rotax oil bypass thermostat (this regulates the oil temp to 90 degrees c), (do not use the cheap empi ones, you are better off not having one than using those) it then goes to 96 plate oil cooler mounted in behind the nose cone with a fan, a hole is cut in the nose cone and duct work to guide the air through (I found this absolutely essential) and then through a 47 plate cooler at the rear (Probably not needed). I don't know this be adequate on this motor yet, but it is more than satisfactory on my 2.1.
I will post a picture of it in the car when I get home which should make it self explanatory

Ok cool so where the factory filter goes do you have a block off plate? New motor looks like it should get along allright!

Yes if you look at the picture of the motor you can see the adaptor plate with its external connections just below and to the left of the distributor

Still haven't got my buggy back from the Muffler shop, I've given up on going to Stockton since I still have to tune the carbies yet, I might have to settle for a few drives closer to home :(

Well I've got it going now, only had it running for about an hour and i've had to reduce the idle 3 times, it was running excessively rich but it seems to be leaning out as it loosens up, having a few problems with next to no fly wheel, I had very little fuel in the front tank and I was trying to go through a gap in the traffic, I couldn't get it to go initially and as I ran out of time I gave it a bootful and pretty much dumped the clutch, the result a pretty big wheel stand across the traffic :oops:

No offence Tratty, but I thought you were going to break this one in gently?

I don't think wheelstands are a part of that procedure :lol: :lol: :lol:

Well I am but I had got my self a third of the way out in the traffic, I was starting to panic and needed to get moving, it was only 7 or 8 metres.
I'm pretty happy with the way its running at the moment although I am having trouble with it not firing at an idle on number 2 cylinder it's not a blocked idle jet and it's not spark, I suspect an air leak some where just need to track it down, I just need to wait till Tuesday so I can buy a few jets and trim it up a bit. I still haven't found any info on adjusting the trijet, I have been talking to Matt Berry and we tend to agree that maybe if you get the main jet right the trijet will look after itself, but if anybody has any info out there it would be gratefully appreciated.

Good work man!! Great to see you are nutting it all out!

Once you get it all sorted and run in, you'll have to come for another weekend visit. I've found plenty more local play areas since you were last up here :D
