You obviously have your head screwed on the right way Grant...reinforcing the engine prior to upping boost etc shows a very sensible and thorough way of getting horsepower and keeping it.

It's a pity that people these days don;t think it through a bit more, but I guess it must be just "old fashioned dinosaur talk" to build a strong motor before working it hard.

The 440 in the Dodge has been built in exactly the same way. I have used the best possible gear that is either aftermarket or MOPAR (Chrysler).

I know that I can give the engine a thorough work out and it will still be as strong and as powerful as it was when it first came out of the engine builders shop!

I constantly come across the 'bolt on brigade' though my work and they figure by bolting a Garret TO4 onto their standard Pulsar ET, throwing in extra injectors and piggyback ECU's, all V8's should go and hide because they would get their American asses kicked by Jap Turbo Tech.

Pity they are always being repaired with broken gearboxes, broken drive dogs (wheels just fall off), melted pistons, broken rods etc etc They spend more money on the repairs than by thinking it through in the first place, picking the righ gear and getting people who know what they're doing to do the machine work.

To come first in a race, first one must finish!

Just had Unichip fitted no other mods 190kw to 225kw rear wheels

XR6T is one impressive vehicle standard but this simple mod improved it right across the rev range and in everyday driving conditions :D

Lot of respect for Rob Harrods opinion though.

Ford has used cast eutectic (spelling?) pistons in the turbo which are the best you can get for the job.

Turbo6man.

The pistons you have commented on,What is the composition and how are they casted?.Why are they better then Forged pistons?.

I saw the motor on the T that let go in Sydney and they commented they are excellant as well but will not withstand anything touching them like a valve etc as they just bascilly explode.The forged pistons I think will withstand a knock or a slight touch if you were unfortunate to have this happen to you.

As I understand it they are an alloy piston - the type of material and the casting is especially suited to turbo motors. I am not aware of the exact composition of the alloy but certainly have had no probs with the ones in my motor which has now done about 100,000 km in the last five years since being turboed. I did a lot of research before working my motor as I didn't want it breaking, and I was told by several turbo engine builders that they were better than a forged piston in this application, and I have no reason as yet to doubt their advice.

Sorry I can't offer more specifics ...

I agree with turbo6man. Those pistons are excellent and you only need to change the rods at 500+ rwhp. In my opinion when a shop gives this advice then they are trying to bleed money $$$ out of you. Did he ask you what power level you were aiming for?. There are a dozen more important modifications you need to do before the rods are replaced with stronger ones. To name a first, high flow injectors/high flow fuel pump/ engine management issues/ larger intercooller/larger turbo, better inlet exhaust manifolding and most important in the case of a manual is a stronger replacement box.

Lets set this straight ,I do not try and bleed money from anybody.I had a phone call the otherday from a guy that stated that he wanted to start with changing the internals of his engine to start with ,then start putting some more boost into the engine.We spoke about warranty issues and he is happy to loose his ford warranty.He spoke about all the things that he mentioned and I agreed with him.I sugested that we speek more indepth and that was as far as our conversation went.So please dont start stupid threads that are damaging to peoples reputations.

Guys, just to reiterate, Rob has a great reputation and when you consider the groups that he does work for then I am completely happy to put myself in his hands.

If you're opinion is that you don't need to do the things he is suggesting, then don't. I just know that a year or two down the track I won't have an engine that's fallen to bits because the internals couldn't cope with the load.

No digs at anyone by the way, I just think it's funny that people who own and drive these cars would think that they have more of an idea than Rob.

(Apologies to the mechanics/engineers amongst us)

Cheers
