lol, was guessing that would be the case...

Cheers for the quick reply Dave

Hey all, Wanting to know if the output splines are different for the jap boxes going from narrow to wide block? & whilst I'm at it, the wide block I have has the extension housing for the latter shifter, can you use the shifter assembly from a narrow block to bring the shifter back forward? Chee...

If you want to know number of splines of wide block borg & jap or narrow jap I've got a few things to count in the shed if need be

I've been running 3.5mm off the head for a fair while now. -Unlike cheater suggests, I haven't got the tensioner packed to take up the slack at idle, which is rather foolish of my self. But I'm still running factory 2lt cam etc etc, so no extreme loading of after market springs and aggressive ramps ...

What part of Victoria.....

Sorry to hear

Love seeing some enthusiasm in a new member; especially at that age when its all fun :thumpsup: ...but seeing that kind of rust in a structural part of a car kind of makes me cringe. Fixable? yeah, everything is fixable, but paying someone to repair that "properly" would blow out. Maybe lo...

All except GE & GN that were fitted with an auto.

Or did GE's come with them too pretty sure there max was the 2lt

If you don't mind my asking... whats it going to cost you to have this done?
-Have toyed with the idea myself (seems most have lol)

I've NEVER seen another Galant around here. Seems to be plenty of datsuns, the odd mazda, corolla etc, and of course plenty of Sigma's and even a rather nice scorpion I often see an old guy driving, but... not one Galant ? Even now i get people asking what year model Datsun is it ? :facepalm: No ide...

Should have a spare diaphragm here if that's all your after?

PM if so.

No such thing as a stupid question, that how we learn

As the astron engines run an alloy head, they are fitted with hardened valve seats.

So no need for additive.

Welcome to the site mate,

If you would be able to post up a few pictures of the hoses you are referring to, I'm sure there will be a few of us that can help point you in the right direction.

Did the engine cut out before hand, or is it mainly after you have changed a few things around?

Nick.

As above, these are a very different platform to the 4g6# Went and doubled checked my g94 & seems to measure up to a narrow block pattern. -When my shed is back in order... can try bolting a bell housing to it if your really wanting to know? Also worth a mention... If your planning on putting a ...

As far as I'm aware, these were engines supplied to dealers for change overs - in cases where it wasn't practical to have both on hand.

Thanks for your help... I am having the carby repaired at the 'Carby Shop' ..Nigel says there is a ball and spring valve adjoining the float bowl which will be the problem with the accelerator pump. Regarding the dizzy vacuum advance...what can be done to repair the diaphragm? Last time I checked n...

Can be a result from many factors, so bit hard to say "it's this" with out having the car to look at. Bit more information might help get to the bottom of it though. -when does it mainly do it? when cold? or at running temp? -Low RPM mid, or high? -Under gentle throttle or hard throttle? H...

My sigma has this exact same prolem. The problem can be brought on moreso if you're running additional accessories. For example, with it in neutral (and with the automatic choke worn off), the engine will happily idle @ 900rpm. If you turn on electrical accessories one by one (ie. wipers, cabin a/c...

Just curious... What are you wanting to know for?

dcoe even ? 40 45 48 ???

astron 1 2.6 are dished to suit the smaller head cc, as the 2lt use flat tops.

Not sure what your asking with the cams ? heads ?

Yes, the astron 2 head on a astron 1 block will yield an awesome comp ratio, but from a potential point of view... the astron 2 head is far better!

head to a wrecker and get your hands on a RWD astron 2 inlet manifold for a carby. Can be found on the GN sigma's, & some scorpions. Also some of the Pajeros & Tritons that used the astron 2 2.6 should have a suitable manifold. check it for corrosion. Ensure the rear water passage on the ast...

Why would you sit a freshly skimmed head in the dirt ???

Good to hear your on the road to recovery

Looking good mate.

Can't offer any advice one paint myself... i really need to learn though lol.

Keep the progress pics coming.

Keep in mind... that your technically not comparing a 2.6lt Vs 2lt there, its more an astron 1 Vs the astron 2.

& yeah... i have a similar modification on the bore

(could really use that 'wanker' icon we had at the moment ... lol)

Very nice!!!
Where did you get the head from Dan? ol' mate from ebay?

Nick.

astron 1 and 2 heads are identical apart from the cams (or so i believe) Quite a lot different actually. As you have already found, the chamber is a bit bigger on the astron 2's (and this will vary again depending on which casting of the head you have, above exhaust port 2 there is a casting like M...

30mm longer arms? NICE!
Got some pics of your new found camber?

Hmm... old thread? how'd i miss this

Thanks for sharing
