Is the extra coolant tank advisable if engine upgraded?
Discussion
I am currently trying to price up exactly what I want/need to go with a Powers Performance engine upgrade.
I think it may be wise to buy a new radiator and silicon/SS coolant hoses/pipes, and have those changed while the engine's out.
But what about the extra expansion tank that some cars seem to have? Would this be considered a wise upgrade for the higher output of the engine, and if yes, what's involved/how much would that be roughly?
Cheers

Yeah did that myself.. You could ask Dom I guess or get him to quote you on doing it 
That was DEI Floor and tunnel. It has a rigid front so can be cleaned off easily and has a fibre glass barrier backing to reduce heat and sound.

Dom is expensive, so only want to use his hourly rate when I absolutely need to..

Mine has the extra coolant tank as standard so can,t help you there but if you go for the 4.5 Dom puts bigger fans in anyway, not sure about the 4.3
Its silly not to get the hoses changed to silicone while the engine is out, I did, whish I had the heat shields renewed
Here is another one for just to increase your headache, I should have got the exhaust wrapped as well
I have also had the 330mm grooved brake upgrade as well, its ok going faster but you need to stop faster, far better than the original wooden brakes the bigger ones stop much better and you can feel the brakes and apply differing pressure to the pedal rather than on or off
Bet your glad I replied
Picking mine up Saturday after 6000 miles
Well, I have decided to have a £12k loan to cover the engine upgrade before or just after Xmas. I am hoping this will cover the extras required, and I can have on the proviso that I won't be spending much more on the car after this - so I have to make the upgrades count.Its silly not to get the hoses changed to silicone while the engine is out, I did, whish I had the heat shields renewed

I am seriously thinking of buying brand new cats (£600 for the pair) too, as I know that old cats can be a bottleneck (and de-cats are just too damned noisy..), and perhaps having the manifolds ceramic coated.
As for the brakes, I may just get the Tuscan S/Sag discs, I don't know yet, but these are things I can get anytime. I am hoping that once I've had the upgrade to the engine, I won't need to spend so much in one go again...I hope..

Have a look on the Tuscan parts Wiki...there are alternative CATs there @ about £300/pair. They are perfect btw.ETA - Couldn't find the cat from the Tuscan link - but I found this:

Are they as good as OEM though? I worry when buying stuff from EBay, especially something that could bork the engine if it fails...

Someone did say that ceramic coating the cats wasn't a good idea - is that right?
Have to be careful, have £12k to play with, not £20k - I know I was charged a small fortune just to have the TB gaskets changed, while the TB's were off, so have to be very careful with the labour charges...

Dom will only warranty his rebuild with his approved Cats or none.Have to be careful, have £12k to play with, not £20k - I know I was charged a small fortune just to have the TB gaskets changed, while the TB's were off, so have to be very careful with the labour charges...
So, if I wanted to have the cats changed (or they needed changing after inspection), I would have to buy Dom's stock, rather than the £600 per pair OEM from HHC?
It is increasingly looking like I will have the upgrade, rad and hoses and nothing more - but I will email Dom nearer the time to ask for a complete price breakdown of what I want.
For me, I figured the important upgrades to go with the engine will be coolant system and ensuring cats and lambdas are in tip-top condition.
As my clutch seems perfectly fine, I may even not have that changed, but buy the clutch, flywheel and slave cylinder kit afterwards, along with new speed transducer, and have them fitted at David Geralds, and while the gearbox is out, get Readman Racing to pick it up and upgrade it to CR - about £3-3.5k in all. But I could have this done later.
I am now assuming the extra coolant tank isn't really needed....

Why don't you email , Dom now and ask him what he recommends based on your budget, he does know what he is talking about
Don't forget you get a warranty
I will - I just wanted to know anyone's experiences and costs of adding the extra expansion tank (initially..).Why don't you email , Dom now and ask him what he recommends based on your budget, he does know what he is talking about
Don't forget you get a warranty
From what I gather, it's not too necessary.
Will certainly ask Dom's advice regarding cats, though..

I would not worry too much about extra expansion tank, Dom has designed his engines too destruction, that's why he offers such a good warranty
The problem posting on here is there will be people with their own ideas, which is fair enough but you need to speak direct to Dom, as I said tell him your budget
Don,t forget the price of the 4.3 does not include large injectors and heavy duty starter motor which is about £1000 so that takes it to about £9500 plus you need to allow for unforeseen things, you might need a new clutch etc so allow another £1000 that takes it up to £10,500, I would put new silicon hoses with fitting is about £350, so your £12,000 budget is getting near, have you factored in the 1000 mile service after it has been run in which is about another £500
Cheers, I know the basic upgrade is just over £9.3k (including the starter and injectors). I am not too bothered about the clutch for now, as I plan to have the gearbox refurbed and CR gears added anyway - so it's gonna come out again at some point. I will order the SS pipes, silicon hoses from ACT, and the rad from here:The problem posting on here is there will be people with their own ideas, which is fair enough but you need to speak direct to Dom, as I said tell him your budget

So all I'll need extra from Dom are engine mounts (which I assume will need changing) and perhaps new connectors on the rad fans. That's the plan, anyway.

How old is your clutch ?
Chris
Trust me on this, once Dom takes your engine out to upgrade it there will be things that need doing to coup with the extra power and some things that have worn out
No point in getting a big engine put in and spend all that money then a week later something brakes and it's back with Dom
I don't know how old the current clutch is, to be honest - but I figured that, if I have the 4.3 done in around December time, as I understand it, there is then a 1000 mile run-in period where you can't go above 3k rpm (is that right)?Chris

Over the Winder months, I will not cover that run-in mileage, so am assuming it would be perhaps March before I have the service - and by that time, I'll have more than enough savings to cover remaining upgrades, like gearbox, clutch (if not done before), new tyres (40's on the front) and finally, the icing on the cake, a full geo set-up to help sort my new crappy Nitrons.
That's the plan, anyway - and barring me being out of a job in the meantime, I'll stick to it..

Yes the run in is 1000 miles, and no you can,t go above 3000 Revs Over the Winder months, I will not cover that run-in mileage, so am assuming it would be perhaps March before I have the service - and by that time, I'll have more than enough savings to cover remaining upgrades, like gearbox, clutch (if not done before), new tyres (40's on the front) and finally, the icing on the cake, a full geo set-up to help sort my new crappy Nitrons.

What's wrong with the existing gearbox works fine for me, I would leave the existing gearbox and get the clutch done while the engine is out, but that's my opinion and save the money for other uprades,
Is there a problem with the Nitrons, biggest issue I had with Nitrons on my Cerb the rear springs was too soft and I got it set up a few times and it still grounded out till I got stiffer springs but by then the Nitrons was f---ked so had to get them rebuilt £480 and that was just the rears , fronts was £120
Seems like you have a plan and your going to stick to it anyway
P.S. You will love the 4.3
I loved the three CR gears in my first Tam - especially changing down to second on the motorway to overtake!
My Nitrons are too hard right now, making anything other than smooth roads a nightmare - and I have never minded a hard set-up before, but these take it to a whole new level - great for track days, bone-jarring for normal crappy UK roads. That is the only upgrade I have thus far regretted.

The 4.3 is so much different than the 3.6 (obviously) it has far more torque so you don,t need to rev the nuts off it to get it going or constantly up and down the gears as you do with the 3.6 so overtaking is far easier
Its up to you but I would get Dom to check the clutch, he will anyway and advise you if it needs changing, personally I would get it changed as the engine is out then try the new engine then decide if you need to change the gearbox, I am only thinking of saving you money
That's unusual with Nitrons being too hard have you turned them down a few notches
I am running Gaz Monotubes and I am really impressed

I will see what it's like after the upgrade, regarding the gearbox. I would imagine 1st on the standard box would be virtually redundant though, with that extra torque!
