From memory, U dont have to take the camshaft out (but I'm running off an old, faded memory)

As far as replacing the head,it really comes down to the price of repairing the current head compared to replacing it...me personally, it repair the original head

G'day Peter, I've been following your channel since the the beginning of your XW restoration and always look forward to an update. I've been meaning to get in contact fact with you regarding the Sigma as I have plenty of Sigma literature (former mechanic at Dandenong Mitsubishi, former employee at P...

Certainly looking the goods

This is something I investigated for my project.... perfect for the situation of N/A or NLA/Obsolete etc......or if U just want to try it urself

As far as diffs go, Ur out of luck......like jamming a Colorado diff into a Torana Different stud patterns (4 to 6) different suspension (tritons are leaf sprung) Brake master cylinder would be way out of balance with the different brakes.....which will change from disc to drum There was a trick whe...

Yeah I've seen reviews of por15, none of them are -ve

Is this car road legal?

I doubt they go for more than scrap tbh.....there was never really anything rare, special or limited about them (apart from the handful of DOHC heads that were made in Japan.)

If a mate has a spare head around.....a slab of there fav drink is usually a fair exchange

Personally..for simplicity reasoning...id tickle the original '54 head to increase the compression

I didnt think the size of the combustion chamber Had a direct effect on the compression...that usually deck height and piston design.......Astron I '54's run dished pistons whereas the Astron II '54 has flat-top pistons, squaring off the deck and increasing compression

May I ask what benefits the '52 head gives over the '54??

Seems a bit of any unusual choice

Sedan is wider......I'm not sure of the dimensions but from memory it's a difference of about 2" (50mm)

Speak to Ur local diff specialist..... he may know of a regular build for Ur application

He may be able to guide you to a relevant car for a conversion

What about looking at something "outside the box" (pun not intended)

Getting a complete disc to disc rear-end from a smaller car.....say a base model impreza...what about an E30 BMW? (I'm not sure if these cars have IRS or not...more merely a suggestion)

Ever thought of it to be honest I'm not sure of the answer but if I was to take a guess (and I emphasise the word "guess" ) I'd say 1) it is possible that the exhaust valves have gone through some form of hardening process to tolerate the heat of the burnt gases 2) some form of chemical re...

Sedans me wagons are different widths....

About the only (asthetic) components that are interchangeable are the guards and front doors....and even then there may be some slight differences

I've heard that the galant VR-4 centre are good......and have heard that the starion centres aren't too bad......but I've had no personal experience with either of them

Anything from the 70s will suit the car IMO.....

As expensive as they are.....the XY GT Phase 3 mirrors would look good..... especially colour coded

.................dafuq?????

This Is a classic build!!!! I'm loving it!!!!!

As far as I'm aware.... production of such an engine stopped many years ago (automotive production doesn't exist in Australia anymore and I can't see the benefit of running the same engine that was built 3 decades ago.......) Also, this "can't run an older engine unless it's on lpg" law se...

Unless it's going on an original turbo sigma.....pretty much nothing these days......everyone is going for far more modern technology

I think a handful of scorpions have run an SR20 Personally I'd stick with the '63 for simplicity reasons U can look at basically anything if u drop enough money in them Ford Focus "Duratec" engines end up in a number of escorts U can look at various Hyundai/late model Kia engines as they a...

Diminishing numbers is no doubt a factor.....don't forget......we are aging also.....Sigma's and Galants aren't for the youth like they once were

Sadly yeah.....gone are the days where we used to get 12-15 people in the chat room

EFI conversion?
E85 tuning?
Turbocharging?

Avenues I'd look at before any "drastic"

Just set it up so it runs reliably......pace is irrelevant if the car breaks after its 1st run

I'm still around......in the process of offloading my Honda z360 for a Sigma wagon

Never heard of such a conversion......there are a handful of inline 6s getting about but they are either very poorly executed or are completely custom and have gone into the firewall to overcome the handling issue.. If u want to drift a Sigma/scorpion, pick another engine If Ur insistent in using th...

4G63 SOHC from an L300 is my 1st choice
