   A pretty low spec turbo build would see you there. Then you could save and go crazy!

   If you can afford a turbo, I am sure you can afford to upgrade the exhaust. You will never achieve that power N/A
   
   A VTS will struggle to see that N/A

    whats involved with supercharging it? is headwork nessecery? and does it require special fuelling?

    hence theres several vts running over 200 on here n/a
    
    to get a vtr there n/a it would be very peaky and have a very small poerband high in the revs
    so would be hard to keep in the power

    headwork benefits it
    youd need low comp pistons and an ecu to run it (its basically the same as a turbo setup for the motor itself and fueling)

    vtr's also have a lower compression than the 16v don't they to start with?

    iirc they run the samew pistons so id have thought the same compression but im not an expert on compression ratios

    are we talking about at the wheels or at the fly ? i hope not wheels lol! you will need a hell of a lot of money and a lot of work , best bets getting a forged 1.8 stroker kit for the vtr with a turbo maybe a t28 ? and nos muhaha

    different pistons, hence why you cant use 16v head with 8v pistons as they will clash
    
    RE the main question, boost is the only way on the 8v unless you have very deep pockets for a NA race engine

    Theres a lad on the rallye reg with a s2 8v with a sandy brown/mark shillaber engine thats suppose to be 162 at the fly.
    
    He has:
    DTA ecu
    QEP big valve ported 8v head
    newmans phase 4 cam
    catcam springs
    16v bottom end with valve cut outs in the pistons 11.6:1 CR
    Supersprint exhaust manifold and pug sport/scorpion system
    SB inlet manifold and R1 bike bodies with larger injectors
    
    IIRC it made 136 atw with sandy
    
    Not bad for a touch over £3000 with mapping etc. BUT what could you get out of a 16v with £3k spent on it? Alot more user friendly power with scope for more is what

    well some people prefer the lightweight of the 8v engine so you get a better balanced car.
    Personally if the bore size is the same (i dont have any details to hand. I would ditch the vtr engine block, look at the rallye or 205 xs alloy block for lightness then fit all the parts VTStom mentioned.
    16v is not the only answer.
    
    I'm working out a lightweight engine for my car and it will cost a lot more than buying a vts engine, but sometimes theres more than just cost as a consideration.

    i was looking at the s1 rallye block with a wild cam and a bit of fettling with pistons/headwork. i know its easy to do the 16v conversion but i like to be a bit different... i think im going to get the running gear right then get a bit more out of the engine
