For alternative EMU chips, ask your local Vauxhall dealer.

For performance exhausts, buy "Car and Car Conversions" magazine and look
through all the ads...

    Ian,
    
    Just curious, what are the differences between the SRI and the SRI
    130.  What sort of speed, depreciation and trimming?
    
    I've always wanted to know, whenever I notice one!
        
    Rob.

    The SRi 130 has a 2.0i engine in it and the standard SRi has a 1.8i
    engine. As for other differences. I think different alloys are about
    it.
    
    
    			Ian.

    Re -1
    
    Really, I always thought they were both 2.0i but the 130 had 130 BHP
    and the other had 115 BHP...
    
    Or mabie this is only on the latest models ??
    
    ..Craig

    I`ve got magazines at home with all the details i.e, 0-60 etc
    I`ll put them in here when i`m next in. The difference in engines is
    definately 1.8 and 2.0 in the mkII Cavalier.
    
    Ian.

    
    Re .8
    
    Oh no it isn't! :^)
    
    The late model SRi's both had 2.0 injection engines, but one gave 130
    bhp and the other only 115 (like in the CD model). As the 130 was a
    late model, I suspect it was bought out to test the new SRi engine 
    before the new style Cavalier arrived.

    Hi,
    
    
    I have just received all the details about the PMC conversions for
    Astra GTE's and SRI's.
    
    There are two types 140BHP version and 158BHP version.
    
    If anybody is interested I'll write up the details here.

    Hi,
    
    Here is info that PMC sent me.
    
    PMC 158BHP "POWER KIT"
    
    Consists of Uprated Electronic control unit to soop up the engine
    management system. Although apparently the smoothness and reliability
    are not affected.
    
    Sebring Performance exhaust. Austrian made with 2" diameter bore
    designed to reduce back pressure improving this application by 48%.
    The system doesn't increase the in-car noise level as it is
    alluminiumised also carrying a 18 month warranty. Has twin 70mm
    diameter chrome tailpipes.
    
    Sebring four branch: coupled with the exhaust the four into one
    manifold inproves low speed torque. Quality is said to be excellent
    zinc plated for durability.
    
    Stage 3 modified cylinder head: The head casting receives modification
    to the valve throats and combustion chambers. The valves are replaced
    with larger ones. (43mm Inlet, 38mm Exhaust). These are manufactured
    from a lightweight material and are of a "rimflow" design for maximum
    effeciency heavy duty valve springs also included.
    
    PMC 281 high torque cam kit: Made form a genuine GM blank with heat
    treatment. The profile is designed to give excellent flexibility
    through the rev range. Total valve duration is 270 and the valve
    lift is increased to 12.5mm. New cam followers are also included.
    
    When fitted the car retains its low speed refinement, but dramatic
    mid and top range improvements. Especially noticed when overtaking
    in 4th/5th.
    
    All this comes with new necessary gaskets, fittings, spark plugs
    and pipercross filter element.
    
    
    The 140BHP "CITY KIT" utilises the same components as the power
    kit without cam and head improvements.
    
    
    PRICES:
    
    158bhp Power Kit = 1199
    kit fitted       = 1450
    140bhp City kit  =  675 (No fitting)

    improvements/body styling accesories etc.
    
    Lastly I have a copy of the review that Car & car conversions conducted
    I can send you this also if you wish...Probably be easier though
    to send it internally cos the a couple of pages of gumpf...Really
    good review though....They report that it is better than the 16V
    version ....

    	Can anyone help me?,I drive a Vauxhall Nova 1.2L 1983.Everything is 
    	sweet in the garden until i decide to change into third gear at 
    	around 30-40 mph,I find that my car really growls.When i say growl
    	i mean the exhaust sounds really rough,but it only seems to happen
    	at between 30-40 mph.Has any of you Vauxhall Nova owners had
    	similar trouble.I wondered if it was just a case of getting a new
        exhaust box?????
    	
    	HELP
    
    	CHEERS!
    	ANDY>>
    

If it also ahppens at around 75 mph, then you've got a resonance growl.

Check the timing.  Retarded timing can cause exhaust growling.

     R.E.16	
    	 Fortunatly It doesn't growl at 75mph,so do you think it could be
    the exhaust??????
    
    
                ANDY.
          

Are you sure it's not vibrating against the bodywork?

    
    		Hi i'm back!!!!
    
    
    	Well i replaced my exhaust and again everything is hunky doryyyyy.
    		
    	cheers
    	
    p.s. to any nova owners at Kwik fit the exhaust systems costs 60 quid
    not bad????????????????????????????
    
    	Andy.
    

    I had a chat with an acquaintance last night who used to have a
    Cosworth RS500 with various mods that put the power well over 500bhp.
    
    This person owns a Rolls Royce which is used for Weddings and the like.
    He also owns an Espace, which is often hired out for the same functions
    to carry the rest of the entourage around.
    
    Besides hearing tales of these vehicles and their problems, he has also
    owned a number of motorbikes of 750-to-1100 cc sized engines.  Further,
    he used to compete in off-shore powerboat racing (not the top class).
    All enough to make you quite sick...  A real power freak.
    
    Anyhow, it seems that going around in the Renault got to him in the end,
    he has now changed that for a Ford.  Another RS500, this time with only
    480bhp claimed power output.  What a b*st*rd !   ;-)
    
    He needs a new exhaust for this, so checked around.  He has ended up
    deciding on a system from Turbo Technics, which has a 4-inch bore.
    They also felt that the tailpipe wasn't big enough, so fit one of 5
    inches in diameter !  O.T.T. or what ?
    
    They do claim this system can increase power output by up to 20bhp,
    depending on the state of tune (or number of modifications) of the engine.
    
    He did talk with them about various conversions that they have done,
    or that they know of.  Of course, being a competitor, they had something
    to say about Brodie Brittain Racing (BBR) and their conversions.
    What they said wasn't exactly bad news though.  They claimed that their
    own conversions on the Cosworth engine can get something like 800bhp.
    They then said that BBR claim to do a 900bhp version.  This they dispute,
    saying they had one of these BBR cars on their rolling road and it put
    out 'ONLY 860bhp' !!!  All this on a rear wheel drive vehicle ?
    
    J.R.   (sounds like fun, expensive, but fun)
    
    
    PS, This person blew up the previous RS500, so feels that the lower
        power put out by this one may be a bit more reliable...

    
    800-900 BHP from a 2 litre 4 cylinder engine?
    
    How do they get such figures? Even the works Turbo Sauber-Mercedes had 
    trouble attaining such figures and that was with a 5 litre V8!!!!!
    
    Mark 

>>                  -< Was this chat in a pub, by any chance? >-
    
    Sort of - but as I said, this info was definitely not first hand.
    
    The owner of the RS500 told me what he had been told by Turbo Technics.
    (he wasn't drunk at the time, and nor was I for that matter ;-)
    
    T.T. also claimed some tales of a road going Gartrac 4WD Escort that
    can do 0-60 times in the 2 second region - rallycross performance.
    
    
    Anyone in contact with BBR of late, who might ask what they quote as
    their maximum figure for the Cossie engine ?
    
>>    800-900 BHP from a 2 litre 4 cylinder engine?
    
    With a big turbo, silly cam profiles, double injectors and a
    bl**dy clever engine management system.  Even then, it does sound like
    a lot of bragging, and not a lot of fact.
    
    Still thought it worth mulling over in Notes.
    
    I do know that 600 bhp is a figure available from the RS500 engine,
    with all the mega-mods that can be made.  Half as much again - how ?
    
>>    How do they get such figures? Even the works Turbo Sauber-Mercedes had 
>>    trouble attaining such figures and that was with a 5 litre V8!!!!!
    
    But the F1 guys got this level of power from smaller engines when
    they used turbos, so it is possible (but not likely from a Cossie).
    
    J.R.

    Can anyone recall the absolute power output that David Vizard
    managed to get out of a Pinto engine on a test bed (quoted in CCC) ?
    
    In his case, he had all sorts of head/valve work, with concrete in
    the waterways to give the block added strength.  I also cannot remember
    what sort of induction was used - carbs/inj/turbo/super/nitrous.
    
    J.R.

    Oh well, CCC have an article this month on some *serious* Cosworths.
    
    Highest power quoted is 540 bhp...  (max speed of 179mph also quoted !)

    I have had an ANSA exhaust fitted to my GTV6 recently and thought it
    may be worth a mention if anyone is considering this 'brand'.
    
    The quality of this exhaust (rear two sections/boxes of my system)
    appears to be very good, with a black 'powder coated' paint finish.
    
    It is supposedly a 'proper' fit in comparison with original parts,
    and there certainly were no problems in fitting it to the car
    (although I did cheat and take it to a local exhaust centre).
    
    It has a 'tarty' rear end with a couple of shiny tailpipes from the
    silencer, with orange paint on the inside of these !  Anyhow, that
    colour is no longer visible inside my exhaust (burning oil)...
    
    As for the sound, it is a bit louder than a standard exhaust would
    normally be - but mine had been blowing for some time so it is now
    quieter than before it was fitted.  The sound-proofing on the car
    also means that it is not really noticeable, unless you open the
    window to listen to it - a nice sound on this car  ;-)
    
    There are also claims that their exhausts will increase power by
    about 10 to 15%, but I read that against almost all aftermarket
    'go-faster' exhausts.  I guess there is a certain amount of truth
    in these claims, if the engine is able to utilise the increase in
    gas-flow that these exhausts can provide.  Not always the case.
    
    I certainly cannot tell if my engine is any more powerful now than
    before then change, but with ten percent, that would be *very* hard
    to detect other than under controlled race-circuit type of conditions.
    
    
    Anyhow, if anybody is considering the purchase of a 'non-standard'
    exhaust, this particular make gets my recommendation.
    
    J.R.

    I think you'll find that ANSA are fitted as standard to many Italian
    cars including Ferrari.
    
    Cheers Ian...

>>    I think you'll find that ANSA are fitted as standard to many Italian
    
    An advert of theirs shows them fitted on the Cizeta...
    
    Also states that they are standard fitment on Bugatti and Lamborghini.
    
    
    I bought it because I had heard that they were 'good', they are
    supplied from (via) an auto factors in Aldershot High Street, and they
    cost less than either the dealer part or an 'unknown' pattern part...
