  1. For those of you interested in seeing how the rest of my project progresses, pictures and everything, free of charge: http://opelownersforum.co.za/viewtopic.php?f=32&t=671
  2. I was going to update my thread until I saw that images are now limited to members only.. I'm not even allowed to see my own images.. don't think I'm going to continue this thread.. I'm out
  3. then again, the 1.9CIH did have a standard camshaft duration of 308degrees.. although it's quite a gentle profile, it should suite higher rpm's..
  4. Hi guys, I've been looking into camshaft options for my CIH project and the info that I have found seems completely off base with what i'm used to.. In OHC convention, the durations are usually as follows: standard: 240deg - 264deg mild road: 270deg - 276deg fast road: 280deg - 296deg full race: 300deg + Now i'm thinking, according to that I'd like something between a mild and a fast road cam, I can safely persue a higher duration because of my butterfly-per-cylinder setup, 288deg ideally, but now i'm looking at the cam specs for CIH engines, and it completely blows my conventional thinking out of the water.. according to this website (http://tekenaar.opelgt.com/Opel%20CIH%20Cams/gtcamspecs.html), standard CIH 19S: 308deg and 9.95mm now, Monzta mentioned that ENEM's Y12 (288deg, 11.1mm) would give a power increase of 10-20hp, but this seems impossible when you compare the specs of the std (308deg) vs Y12 (288deg). am i missing something? Also, I'm having difficulty understanding the @ 0.50" classification for camshafts.. the yanks all have these @ 0.50" denotions for the cams and I don't have a clue how to compare those to the conventional duration spec that i'm used to.. How does one convert: Torquer cam: .407" lift, 216° @ .050" Combo cam: .430" lift, 228° @ .050" Max Comp cam: .430" lift, 248° @ .050" ... into something I can understand?
  5. Thanks for the replies guys.. I was just wondering if i should make mine into a coffee table or sell.. What are the telltale signs of a 400 block?
  6. not so much a technical query, but those were built by cosworth right? how much are these blocks worth (bare) these days, and how widely available are they?
  7. Hey chaps, I saw this on a chev ascona B recently, and couldn't help but notice its almost the same as the ones on the ascona 400 rally cars.. Do these steering wheels have a specific name or brand they go by to help with the search, as i'd really like one for my manta..
  8. identifying blocks is easy yes, but are all the hang on parts the same? are there any physical differences apart from the bore and sleeve size? Also, how do you distinguish between the cylinder heads? i read somewhere that you count the number of "fins" at the front..
  9. Hey guys, apart from the bore and pistons, what other differences are there to these engines? obviously the 1.6 cylinder head also has a smaller combustion chamber, but is there any way to tell them apart? (numbers etc)
  10. Don't know the Nikki Carbs at all but idle generally depends on both the mixture screw and the idle jet itself.. idle jet determines the flowrate, mixture screw the ratio of air to fuel.. something could either be blocking the idle jet slightly, or it's just too small for the 1.9.. once again, not sure if that's an item that can be modified or interchanged on those carbs..
  11. and the difference between the "n" and "s" can be taken from the engine number?
  12. Hey guys, firstly, are there any differences in brakes between the 1.6 and 1.9 manta A's?
  13. Update.. I never thought it would be advantageous living in South Africa for modifying a manta A, but i stumbled onto something quite special recently.. As some of you might have seen, I was struggling to fit the sidedrafts to the current 1.9 setup as the RHD manta brake servo and master cylinders get in the way.. I vaguely remember seeing an article that pertained to the South African manta's, and the "manta S" conversion that was offered as an aftermarket option which included a more aggressive camshaft and sidedrafts.. Now, nowhere in this description there's any mention of relocating servo's and master cylinders, so 1st prize would've been one of these manifolds, which would be ULTRA rare as hens teeth (only a handful were ever converted).. I was acquianted with a chap that used to be quite involved in the manta scene in the 70's and 80's, and this was what he had for me: as you can see, the intake takes the sidedrafts over the top of the master cylinders so it's straight bolt-on, even gets the fuelling further away from the heat.. how many of these items do you reckon are still in existence? have any of you ever seen one??
  14. with the std top and bottom tank.. rover p6, thanks pal...
