The alternative of a drilled sprocket is cheaper and more durable as the mounting bolt and dowel on the cam are the only things keeping it from moving (I'm pretty sure you can still get them). Just like these ones http://imageshack.us/a/img391/1853/camgear2.jpg these are the gears I redrill , quite...

Where can we get Whiteline sway bar? Hard to source suit GK

Cheers Mic

Do you have more details on fitting inserts? I like the Porsche lashes and are cheap.

I was hoping to go the same path. My machinist currently has my head. M6 mild port, double valve springs, roller rockers and hydraulic lifters. He sent a new cam away to Crow to be reground to suit turbo with roller rockers. Will see how it looks when I take delivery later this week.

Its a Hybrid T3 ebay item 251320003752. I cant find the GT30 internal gate I was looking at. Or its not too late to modify the custom manifold and use an external gate like ebay item 121209924344. I don't want a turbo too big its laggy nor a turbo too small it will choke under 6500rpm. The work done...

Not sure how to read the specs. It says turbine Trim 73 inducer 65.5 exducer 55.9. Need something with internal gate and budget bit over $500.

Now looking at turbo's and have a choice of 2. The GT30 and the Hybrid T3. The GT30 has compressor .70 and turbine .63, and Hybrid T3 has compressor .50 and turbine .63. Whats the effect on compressor size and which one will spool quicker

Cheers

Awsome work you have done. I'm guessing by several part numbers there are varying thicknesses. Just now need to cc the head and choose the right one. I'll call Aaron Monday and have a chat.

Much appreciated Cheers

Where can we find a ICS Copper gasket ?? Not keen on O ring the block or using solid copper gasket unless no other choice. The bottom end is now assembled

Hi all
Currently building new engine, What head gasket are people using?. Boost up to 18 psi and will be using ARP head studs. My parts guy says cometic don't make one!!

Thanks all for the advise T28 will run out of puff early in the rev range but would be great down low gt30 would be nicer IMO. Better off with a xf throttle body but not necessary. Camshaft talk to camtech. I was given 2 turbos T28 from a mate in a shed cleanout. If too small I could upgrade later. ...

Hi all, Siggy is currently running a 128rwhp NA 4G54, which this engine is now 3 years old and has been run hard in nearly 50 local competition events. Siggy isnt for the street, its used for Motorkana, Kanacross, Autocross, Rallysprint, Hillclimb and might try Drifting. Time for another upgrade to ...

Cheers SS

I just emailed them for freight quote. Hope they can be here in 6 weeks for Hill climb

Thanks

Yeah Sounds good.

Thanks

Having trouble sourcing performance Starion front brake pads. Suitable for a modest Sigma in Hillclimb. Does anyone use a decent pad with success?

Cheeers

No worries

Thanks again for your help. Just now need to find the right thrust bearing

Thanks for the reply

I use MMC gearboxes. Borg warner not suitable as I use reverse to 1st change reguarly.

Does the 5mm difference between the block and flywheel effect the starter throw out? or can I put a 5mm spacer in there?

Cheers

Evening all I am looking into fitting a Starion Flywheel onto Astron 2 wide block. These flywheels are 7kg lighter than sigma. The questions I have are : Starion 4g63 uses a harmonic balancer. Do I need to use this with the starion Flywheel? The starion clutchplate is slightly smaller than sigma, th...

Nice pics Mr D. Good enough for me to copy to my computer. Bugger the standard axles, another 1 broken 8o. Cant wait till I build the falcon 4.1 diff.
Anyway good to meet you. Till next time

Dion

Unless you have a pit or hoist, use the engine crane and pull it all out and split the gearbox on the floor. Only use a new standard clutch for replacement, they are good for standard street use. I still use them in very stressfull race days.

Changing front springs and shocks is as easy as changing ya jocks. Just need spring compressors and some tools. You have done good yourself so far and should be capable.

Cheers
