All the way on stock internals....

[JekylandHyde]

Absolutely agreed. Both, a proper intercooler and water injection, would be recommended. They compliment each other. They are not doing the exact same thing.

[^Trickster^]

To be honest, my water injection gives me good peace of mind! And lets not forget how it keeps the cylinders nice and clean!

How do you have it set up?
IE boost related, rev related, manually opperated?

[^Trickster^]

Mine comes in at 10psi when its on.

Thinks Jeffs is pretty much the same?

Graeme

[JekylandHyde]

Exactly ~ boost activated at 10 psi.

[nutter]

I've always wondered why you'd need uprated internals on a car, aslong as everything inside is happening as it should I can't see the danger.

Well, I'll carry on with bolt ons till I get to the point of opening it up I think.

Ahh but how do you know everything inside the engine is happening as it should. Let me tell you a story

Stock rev 2 engine apart from a metal head gasket. ATS TD06, Pace CC. Link XLEM ECU. Engine was running fine on the standard ECU with the Wastegate setting the boost to ten psi. i ran 1000 miles like that. I saved my cash then went to Thor. Had my Link ECU fitted and the boost raised to 1.25 bar. The extra boost highlighted a fault with the cooling system on the cylinder head. result. a days mapping fee wasted, and an engine to rebuild.

Now i'm not saying you can't run 25psi on the standard engine, but i would advise have the engine checked over. The problem is i believe to check an engine properly it's got to come apart so whilst you're checking the engine over you may as well have some forged pistons fitted no?

just my 2p of course feel free to ignore me

Hi Dean,

I agree with you to an extent... But anyone who wants to Mod an engine should a matter of course check the Cooling System Works Properly, Check you Cambelt and Tensioner, Get a compression and Leakdown Test Done..

It really should be known as Standard Practice....

but anyone who wants to run 25psi should either tear everything apart and check it (what about water pump bearings oil pressure relief valves etc??) or start saving for the day that will enevitably come, when the engine will go bye bye

For one i dont care about being safe!!! I want to play to the limit

[^Trickster^]

What was the fault with the cooling system?

You said it had a metal headgasket, was the coolant bled properly?

Was it the correct headgasket, it has been known for people to fit headgaskets that are for a different year which can cause overheating in the cylinder head, eg the rev 3 steel headgasket when fitted to a rev 1/2 engine needs an extra hole drilling for a water gallery.

Why was the headgasket replaced in the first place?

Like i was saying, its definitly luck of the draw with any engine really, plenty of people have spent thousands and thousands on engines and they have failed for no apparent reason, yet you get people who hardly maintin their engine, run low on oil, coolant the works, and they live forever.

It turned out to be a fault with the cylinder head. The fault was minor until the engine was subject to a halfway reasonable pressure. then it would leak the cylinder contents into the coolant system and push all the coolant out of the overflow.

I admit this was a freak accident and i agree that its the "luck of the draw" in most cases. Its just that i know how much extra time, money and effort i have had to spend doing what i should really have done in the first place .

Did you not get a leakdown test done when you bought the car?

[nutter]

yep a test was done. But showed nothing, the garage i took it to could only simulate non boost pressure (about 80psi in the cylinders i think he said). Jsut the way things go sometimes!

Hmmmm ideal is between 5 to 10% compression loss between cylinders... anything more than that you have problems.....

I guess its just one of those things

[matt_mr2t]

Whens yours gonna be ready Nutter?
Your not far from me, wouldn't mind seeing it

[AM TUNING]

i just cant see the logic here,,

unless u have a fully rebuilt engine waiting to go in and want to find out how long your old tired block lasts before it goes bang..

yes u can run 25psi on a tdo6 with good management but what will it prove ,, it will prove to u that it WILL cost u more money in the long run when u not only need new pistons u also need a rebore, and possably a new block if it goes big time,,,

sorry but if u want 25psi then put forgies in the and get a good head gasket in there at least,,

Erm, the question was not "What should I do to run 25psi reliably was it? So lets not all get up each other.

The question was...

I'm going for 25psi with my ats td06 kit..... most of you will think i'm nuts.... but with the right amount of cooling and fuel and a good state on tune why not.....

He made a statement of what was going to be done, If I thought it was 100% ideal then I wouldnt of fitted forged pistons myself.

The discussion was about stock internals.

I suppose it would have to be tuned by AM Tuning aswell?

It'd be hard as he only does mechanical work.

And what's the b!tchy comment for anyway?

IT's all in the state of Tune.... Its nothing to do with how strong things are..!!! Our Engines and internals are strong if tuned right with the right compliment of fuel and cooling..

If my engine blows then i will eat my words... but im making sure everything is done properly whilst tuning.


It has allready been proved that Stock Internals can take a high amount of boost on a high mileage engine.
