Thanks guys, got her going...

Had my dizzy out of my gh sigma, stuffed up the timing an now can't get it to fire, any tips on these electronic dizzies? Any help appreciated, it's starting to annoy me...

No worries, thanks. I retarded mine 2 degrees on the 2.6L when I fitted turbo etc up and she didn't miss a beat the couple of years it was on the road, but I'll keep it in mind for this one.
Cheers...

I see ACL list a range of head gaskets and spacers on there website, no specifics but I'll contact them with what I'm doing an they should be able to help me out with spacer thickness etc. My 2.6l ran its standard dizzy for a couple of years with the turbo set up on it with no dramas at all? Cheers ...

Yeh the 2.6l does run dished pistons, I was hoping the 6-7mm bore diameter difference between the 2L an 2.6L along with the dish in the head might compensate and lower it enough to run the turbo, but will have to compare heads once 2L one is removed. Any one no where I can get a thicker copper gaske...

cheers scorpma82, but I'm using a 2L engine this time which i understand are 9.5;1 non turbo and 7.8;1 turbo. but I'm putting my 2.6L head on the 2L and wondering if this will bring the compression down enough for the turbo, I'm thinking yes but curious if any one else has done it and or had to use ...

has any one out there had to decompression an astron 1, or has any other info on the matter?
cheers...

IS ANY ONE ABLE TO HELP ME WITH ANY INFO ON WERE I CAN GET A SPACER PLATE OR THICKER GASKET TO FIT A 4G52 BLOCK TO LOWER COMPRESSION FOR ORIGINAL TURBO FIT UP WITH 4G54 HEAD OR WOULD THE SERIES 1 4G54 HEAD POSSIBLY LOWER COMPRESSION ENOUGH WITH WHAT LOOKS LIKE FLAT TO PISTONS (THROUGH SPARK PLUG HOL...

hey guys, haven't been on here in a while as i blew the engine up in my gh an it just got parked at the back of the shed, but I'm back on its case now an doing some upgrades/conversions an have a few questions? first of all its a turbo 4g54 with 2.0l 5 speed gear box (very noisy) at the moment, but ...

Just a quick question. Has any one seen Original Power Steering on a GH as i have just picked up a whole car and the guy i got it from said it was original from the factory, and his dad had it from new. First one i have seen. :D :o :shock: I've got a GH with power steering but was fitted after fact...

Hey, i'm currently putting a stock turbo system on my 2.6L GH with a manual conversion as well. This has turned into more of a hassel than what i originally thought but has turned out to be doable dispite the hassels. But now im looking for a diff up grade as of i was assuming i would just be able t...
