    Gt series turbos will spool up faster than older versions. Big jump between gt2860 - gt3076. Gt3076 good for 500bhp afaik, gt3071 for 400bhp+ so both too big for a 2ltr 8v motor imo. Bentley turbos are t3, .64 ex so will flow 300bhp+ and can use an internal wastegate. Personally for 300bhp+ I'd want to use an external wastegate, at least 38mm.

    Probably SFA in peak power for a given boost pressure, but it will be more efficient (lower outlet temp) and should be more responsive throughout the rev range with a much lower boost threshold level.

    It's basically taking advantage of the latest and greatest in aerodynamic and friction reduction technology.

    Most T3/4 turbo's have very old wheel designs.

    Yeah, sorry about that. It was a typo. The 3076 would be a touch laggy :biglaugh:

    It was supposed to be a GT3067. Should suit a 2.2 quite well.

    The new GTX Series look pretty sweet. Looking at a GTX3582 for my 21 :D

    It's a big old blower!

    your'll have to upgrade the front suspension after fitting that!
    Its more of a drag style turbo

    Next one down caps me to 430hp though. And I want more than 430hp.

    Would the 2.1 turbo diesel liners fit in a petrol 2.2 block?

    They are 86mm but could be bored out to 88mm and seem alot more meaty?

    They are 'cast iron' but I thought all the liners were cast iron?

    The other option is to keep them 86mm and use a different piston?

    IIRC Kieran Prentice asked the same many years ago and we decided no. Loooong time ago though. For all the messing about why not just import a set of Steel liners from the UK?

    Can you get suitable liners for the 2.2?
    The Diesel has the long stroke block so the liners are (presumably) the same length as the 2.2 liners.

    Ah, forgot it was a 2.2! Maybe they would have to be a bespoke item then. I've never seen a Diesel liner so couldnt comment, I wonder if they are the same outer diameter but a smaller inner diameter for extra strength...that would mean you boring them out would be pointless as you would just return them to the Petrol spec. Would need to see one to know for sure though!

    Oooof, wow thats a beast!

    Yeah. The peak pressure in a diesel is alot higher than petrol so I assume the extra meat is to prevent distortion on the thrust side. I'm trying to find out if the bare block is the same between a 2.2 petrol and a 2.1 diesel. If they are the same then I could use second hand 'stress releived' liners and just get them bored to 88mm.

    There many 21's in oz? Are they imports?
     
  15. DaveL485

    DaveL485 Staff Member

    A few, but no Turbos. Other than the Quadra I sent over last year.

    There is a couple of turbos in NZ but mine is the only one in Oz....

    Thread revival here. I'm piecing together the bits for the new motor build and got the new Wossner pistons this week. I'm still not sure about whether to try the Turbo Diesel liners and was wondering where the liners normally fail. Do they fail on the thin bit usually or on the thrust side, or is there no rhyme or reason?
    Im starting to wonder if I should get a set of 86mm pistons (or get mine machined) and fit the Diesel liners as is. With the 2.2 crank it would still give me over 2000cc displacement and the diesel liners would give me a bit more meat all around and a much stronger thrust side.
    I opened my big mouth and stated I was aiming for 400ponies but I want it to be as reliable as possible.
     
  18. DaveL485

    DaveL485 Staff Member

    Yes, they fail on the thin outer bits of No1 or No4. Do you not fancy buying a set of steel liners?

    I'd love to, but I dont think they are available for the 2.2.

    I've made that error before haven't I! You could get them made bespoke...worth asking Westwood cylinder liners if they can make the 21T ones but a little longer?
