    So can I just weld the actuator flap shut ? only running 6 psi I want to see what the bare minimum I can use to boost I have spare engine any way fir my main priject this is just fir exoeriment
    I'm going to run compleatly standared engine ( I have bigger injectors tho ) bo inter cooler or anything just bolt on and go till it goes bang so it will be 6psi or less

    What! No.

    You need an actuator on this turbo.

    Fitting is easy. Just go on eBay for a t25/t28 actuator and make sure you get the bracket too. There's a link rod that will connect to your wastegate flap.


    Actuator

    bracket

    Connection is easy as long as you get the correct actuator and bracket.

    If you weld your wastegate shut as advised you will need an external wastegate = more expense and hassle to install, especially if you're using a cast exhaust manifold like pictured. Please don't weld it shut...

    The actuator bracket bolts to the compressor housing and is fairly universal across the range. There are some differences to the actuator though (and its arm length/shape) depending on exact turbo model. You're best phoning some place like CR Turbos who know the details of every model and talking to them - they'll have the right parts on the shelf. Won't be as cheap as eBay obviously but you'll have the right parts, first time.

    Dear DJVTR,
    That is an awfull lot of work, to fit a turbo to a standard engined car. First item I would be seriously looking into, is if your cars electrical and the electronics are well capable of running a fully running turbo ?
    Rather than just bolting on each mechanical part and hoping to see if it works.
    In the 1990,s I worked on SAAB,s including turbo "S"s with water injection kits fitted. very complex cars to work on as a mechanic.
    You have boost pressure guages to fit and get working properly before you can get the mechanicals to bolt on, and lots of extra engine valves and more electronic sensors to fit etc etc.
    Vince,

    Thanks for the Info Vince but this is purely an experiment to see what levels ( if any) will a standard vtr engine will take.
    as said above this is a spare engine to experiment with and my main one will be built over time.
    Witch will be run by a standalone / forged internals / decompression plate ect
    But tthanks anyway
