Yep. I am planning to port and polish, especially now that I have a small manifold leak. So when i fix the leak i will P & P while manifold is off. Don't suppose there is anyway to get right inside...

Evening everyone,

Just wanted to write a quick thread/info warning others about these rubbish Chinese Stainless Steel manifolds as available on Ebay.

I bought one a while back and was distorted...

Mudski is right. I tried a chinese stainless manifold and was total rubbish. Ended up with DTS cast Iron and even though was $530 you get what you pay for. I use a Kinugawa Turbo and am very happy...

Hi all,

Just thought I would create a new thread with my info fitting Turbo to GQ TB42E LPG in case anyone was considering it as follows:-

I have just taken my rubbish 'maid in china' stainless turbo exhaust manifolds as available on ebay. DON'T BUY ONE. They are absolute rubbish. I only paid $185 app, so I pity any poor sole who pays...

I went and bought a TB48 to do just what you are proposing which I still have and it is for sale. It needs a full rebuild and I would suggest you are better rebuilding an engine, rather than buying a...

Well it has been some time and after a lot of consideration, I decided given the cost of rebuilding the 4.8, to take yr advice three dogs and fitted a kaniguwa turbo. Results/prerformance is beyond...

Howdy, want some advice on best Turbo size/configuration to fit up to a 4.2EFI on gas and petrol. Not looking for max power increase, after more torgue than anything else. Extra 40 to 50kw/30 to 40%...

Much better if you could put a TB48 head on it. Got me thinking. Actually, very hard prob impossible considering TB48 is Twin Overhead Cam. ie different timing cover/chains/etc. Prob best to get...

Afternoon all,
Wondering whether anyone has or knows any info/anyone has had any oil or other issues causing engine failure in TB48. The one I have has 2 buggered big ends and cracks to front alloy...

Haven't upgrade from one to the other but have had both carby and now have an EFI model. Much better to drive/response. A good mod to also do is to fit electric rad fans and although reliability...

Especially female change room lockers!!

Could be a vacum leak. My Gq TB42 had one recently. Mine is EFI so many places for a leak. But yrs is carby? Still plenty of places for leaks. Look for splits close to where hoses fit up to manifold,...

G'day, Looking for - 6 x coil packs, Manual bellhousing, flywheel & bolts, starter, alternator, MAF. If anyone has any of these and wants to sell or knows someone who has. Can give me a call on...

I'd like to know how you get on with any info, as I would like to know what year model my TB48E came out of

Have thought a lot about what I prefer. Considered going down the turbo path. But no gain in economy. But fitting a GQ with the far more efficient and powerfull (50% more power & a lot more torque)...

Morning fellas (and gals if any), Preparing a 4.8 to go into a GQ. I need- manual bellhousing, coil packs, starter, alternator, engine mounts, general engine bolts, and other engine parts for a...

Hey Robo,

I can tell you that my KME system now that it is sorted, runs really well and is almost on par with petrol as far as performance/driveability goes. I can give you the name of the guy that helped me...

Might seem like a silly thing to say, but how old is the petrol in your tank. Apparently 91 octane starts losing its octane level/ability after just 1month, 95 after 3 months, and 98 lasts longest. I...

Yep, first need to make sure converter is empty of gas. Run engine on gas and turn of isolating valve at LPG tank. Usually a round brass knurled knob found on tank. Engine will falter and switch back...

Hi Shaun100,
Yep looks the same as system on my GQ TB42E. Although I would need to see a pic of your gas ECU which should be in the engine bay there close to the Converter pic you are showing. If it...

Thanks nissannewby. Will give him a call.
