Another Sigma Build (lots of pics)

[sigma-turbo]

a 9 inch ...is very hard to get here..what vehicle is the BTR from....

BTR (formerly borg warner)

BTR cast diffs can be found in Holden VL onwards Commodores, 1990 onwards Ford Falcons and Aussie R31 Skylines, im sure theres other cars that have them

[sigma-turbo]

well engine and trans are in, had to give the trans tunnel a slight tap

No mods to the sump or to the cross member to fit engine but i did cut the std mounts off the cross member and hat to add a 60mm plate to the gearbox cross member to line up with the mount

Engine is mounted via an engine plate

[nigie]

I wont post pics of the corty in here though I think theres some already on TT

have made some progress on the Sigma though not as much as I would like due to the rain

I swapped the factory Sigma brake booster for a smaller unit from a 1981 Datsun Stanza this give me more room to fit tall rocker covers to clear my roller rockers






Made some tube headers, well I modified a set I had they're not the best design but will do for now, I'll make some 4 into 1's later or I may even fit this GT4202 turbo I have sitting here




A few pics of the finished engine mount plate/alternator bracket not the cut and shut water pump, I had to do this to get enough room to fit a 50mm radiator shroud and electric fans, I will be using a Davies Craig EWP 80 to pump engine coolant





Just need to pull the engine down and put a gasket kit through it and put it back in the car

[nigie]

Great...i had the same problem with the booster whereby i have less tha .5 inch clearance with the chevy tall covers ...i guess if i had used the short it would not have been a problem im using a master cylinder from a nissan wingroad. yeah headers were also a very tight fit have less that .5 inch clearance there also.

[nigie]

Aye sigma any progress?

besides 81 nissan stanza u know of any other small workable booster..

[fatts]

nigie daz not too much heat from the headders?

[nigie]

yes thats why a smaller booster is needed

[droppa]

nigie that booster changed alredy, looks like a b14 or so....try using a jimny turbo one, small and effective...

[nigie]

Yes its a wing road booster....was the smallest i could get at the time well except for 1 jimny which was $800...ill keep looking..anybody knows whos has jimny boosters...

[droppa]

yeah nigie i may be able to link a booster for u, ill check if they hav and the price, i have a EP82 Starlet one, its kinda small and slim, was keeping for a project but will let it for a $150. its more than than in the bamboo, oh and i have galant parts if yuh intrested, not best fu parts but some ok stuff....i kinda scrap my project galant, 4 round lights, was aiming for a VG30DETT and box......

yeah its 99% done i'll be firing it up tomorrow then i just need to make a hand brake cable then off to be engineered and registered

[droppa]

Front still sits pretty high, the S13 coilover is a common upgrade, that would have suit u fine, but i gues u can go up on tire size and raise the back a bit...........i see ur front wheel will be off the ground....heheheh

It sits better than that now as the rear has been raised

S13 coil overs aren't really an option many have no ADR (Australian design rules) approval then theres the problem of getting the correct rate springs and shocks to cope with the weight

If i want it lower i can just get off the shelf Chrysler Centura springs

[nigie]

what are u doing for cooling?

[sigma-turbo]

Well i fired it up today and have taken it on its shake down run, drives well

Cooling is taken care of by a 3 core Holden V8 VK commodore radiator and a davies craig EWP 115 thats mounted under the battery tray theres also two 10" davies craig electric fans, fans and pump are controlled by a digital controller

you can see the alloy pipe that goes from the engine to the water pump




Vid of 2nd start (it started first attempt) still needs a tune

[nigie]

[nigie]

[MISHI]
