Are they mapping it with HP Tuners? I struggled with EFI Live to find the right tables to modify to lower the idle. The live control works fine and it'll happily idle much lower than stock, but despite setting the desired idle tables etc. it wouldn't even consider dropping to it... Bit weird.

There are quite a few tables that affect idle, you have to consider the accuracy of your VE table (in the relevant cells), the control parameters which adjust how tightly it tries to maintain the commanded idle speed, base spark, and a few others I can't list off the top of my head. {...}

It may be worth considering LS3 heads and intake. The cost of an LS2 FAST intake would go quite some way to getting the LS3 top end. They flow well out of the box and would suit your cam spec.

Interesting how LS3 heads are fairly well priced, a set of ported heads even from Summit inc valves are just under $600 a side, mmmm!Any advantage in say ported LS3 heads against a ported set of 243 LS2 heads or say even LS2 PRC heads?

The bonus of buying new heads is that you can sell your LS2 heads to an LS1 owner, as it's a popular upgrade.
Judging by your power/torque figures, there's a restriction high up in the RPM range, so think air flow and the potential restrictions. Your stock LS2 intake is a current bottleneck. Once you upgrade that, your heads/filter will likely be the next bottleneck.
Yep, so I am on the hunt for new cylinder heads and intake.
To be honest it will be a little budget directed (as with everything), so if I find a good deal using LS2 heads like PRC or TSP and intake over LS3 then ill stick with LS2 heads.
I dont want to build a N/A monster just something that does improve the engine but also does give options if I do go supercharged at some point. Hence the choice in cam as it works well in both applications
Intake wise I think it is just going to be simpler to go for a Fast 102, in november my brother in law is heading back over to Vegas so it maybe another time for shopping....
Now I have had a chance to drive the car it really pulls strong, a BIG difference to how it was before. 3k up you really start to feel the torque. Rev limit is a bit high for my liking as itll pull 70mph in 2nd with needle nearing 7k, but that just maybe me being cautious!
Showed a clean set of heals to a flappy paddle E90 M3, so a big improvement to my heavy turd.
I will get the car on Surrey Rolling Road at somepoint too
Anyway, picture time...
I went to Players show at the weekend with my friend, it has a bad reputation but there are some interesting cars that go
Im terrible at cleaning cars and doing it at 1am in the morning isnt fun either, but atleast I think it came up well this time.
Still a few things to do on the car, I really need to spend a day underneath cleaning it up and also the engine bay as it is a little tatty.
My friends Porsche makes my car look huge

Again its about time I should update this thread!
I got bored of the oval pipes on the exhaust so I had my friends garage change them for some straight duals on either side.
Now the have blackend up a bit with the fumes they look great.
I never realized that the Wortec tips were baffled, so the car is louder now and has a much edgier note which I love
Once a year my brother in law and sister go to America for a few of the geeky computer conferences in Las Vegas, last time they went I got my camshaft kit shipped to them to bring back for me, as it saves so much in tax!
This year I got a little carried away with the black friday sales and ended up ordering my bucket list of parts.
I got some really good deals.
I first found some used Dart heads, with 2k use, they were pretty good and fully cnc ported
So I picked up a fast 102, billet lines, ls7 lifters and trays, also some new BTR dual springs with TI retainers
I also managed to pick up a new air filter set up, I went with the XAIR kit from NZ which had just arrived in America. Its HUGE, quality of it is really good and all the reviews of these seem to be rather impressive
As I am going to be changing the clutch at the same time I ordered the rear oil cover gasket and rear main oil seal
I hunted for a new slave cylinder but couldnt get one in time, I was going to use the F-body cylinder and change the fittings however I called Summit and they were expecting a shipment in of new Gto cylinders for $70 so went for those. Now i just need to order a few bits from MF and rip the poor car completely apart
No idea what power to expect but im sure ill be happy with it and hopefully I can get it all done in time for the SRR meet!

That is a lovely looking Monaro you have,I would love to get mine to a similar spec....one day!
I have to say that when I saw the picture of your XAIR filter I was a bit concerned about the jar of mint jelly and apple sauce! I think they would screw up your MAF sensor. Better off with some proper cleaning fluid.

You can see my priorities, food and car parts!!
Decided tonight to build up my cylinder heads
I needed to replace the springs as my cam is .595 lift and the springs that were in the heads have done a few thousand and are a .600 lift.
First I needed to take off the existing springs, valve seats and locators
Relatively simple
Once all the springs are off its just some pliers to remove the seals and locators
I went with the BTR dual springs with Titanium retainers as the were on a really good black friday deal
When using the dual springs the valve spring locators need to be changed to stop the inner spring binding.
Unfortunately mine are the wrong size, somewhere along the line I have been sent the wrong size. BTR were great to chat to and have sent another set out in the correct size, cant fault them apart from the shipping charges at 60$!!
Whilst I am waiting atleast I can get the heads cleaned up nice

Be certain the retainers are wider then the springs by a proper amount. I've come across one race engine where the outer spring ended up outside the retainer with only the inner spring doing it's job. It was a failure about to happen.

Not good!Edited by Boosted LS1 on Wednesday 4th January 20:26
Yep, checked out all the rest of the setup incase any other parts had been picked out incorrectly!
Must say the BTR kit is miles better quality then my previous PAC spring set
You could probably have had the centres of the spring platforms all machined out.
Not even sure why some dont fit over the guides. I've a set here that wont fit too....and have not a clue where they even came from as I've only had a couple of different heads over the years.
The stem seals are a ballix to get off too !
