felixx Posted May 30, 2011 Share Posted May 30, 2011 OK so I may have come accross a 28/36 that needs some love, I have the adaptor to stick it to my std 997cc inlet manifold. 1) Will it make any difference to the performance of my (otherwise standard) car? 2) Are jets available for a 997cc engine? Cost? 3)Porting and polishing my inlet manifold, will it make a noticeable gain? 4) Anything I need to know that I have missed? Quote Link to comment Share on other sites More sharing options...

felixx Posted May 30, 2011 Author Share Posted May 30, 2011 but a bit of lump in the cam would help? Quote Link to comment Share on other sites More sharing options...
Unclejake Posted May 30, 2011 Share Posted May 30, 2011 The best thing you could do to improve performance (without spending too much money or getting a cert) is to fit a 1500cc Mk1 Cortina engine. I can't see going to the effort of modifying your existing motor being particulary satisfying. Your existing motor is a three main bearing engine (instead of the Cortina's five bearings), so if you up the horsepower and revs too much it will fail Quote Link to comment Share on other sites More sharing options...
felixx Posted May 30, 2011 Author Share Posted May 30, 2011 cheers UJ. Not wanting to make her a 100hp beast, but 48hp would be nice LOL Quote Link to comment Share on other sites More sharing options...
Valiant Posted May 30, 2011 Share Posted May 30, 2011 Other than what Unclejake has said there is no easy of adding more power to your Anglia. You could build your 997cc up but I think you would be better off to convert to a more modern engine with more capacity. 1500cc Mk1/2 Cortina would be the easiest option. Otherwise a 1600 cross flow from an Escort or Cortina is a good option. You will find your self needing to get a cert with a crossflow swap though.

felixx Posted May 30, 2011 Author Share Posted May 30, 2011 thanks guys. Well I have a 28/36 and manifold adaptor, shall I put it on or sell it Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted May 30, 2011 Share Posted May 30, 2011 is it remotly close to the right jetting? if you don't know, go see palmside automotive, if its right then you could put it on and see how it runs, if its luck luster then just sell it. the weber was a worthy upgrade on my toyota though.

Mike-e Posted May 31, 2011 Share Posted May 31, 2011 are your brakes up to the task of stopping 50+ horsepower? Quote Link to comment Share on other sites More sharing options...
felixx Posted May 31, 2011 Author Share Posted May 31, 2011 Fliboi, The jets are for a 1500 but I will follow your suggestion when I fit it. Mike-e, Good question, this is a long term project (no $$) and I plan to lower her as well, lowering the front end of an anglia usually involves MkII cortina struts. Thankfully these have discs. cheers Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted May 31, 2011 Share Posted May 31, 2011 that jetting will probably run quite rich, this shouldn't cause any damage, but people may correct me? im not a huge expert on carbs yet, just getting there Quote Link to comment Share on other sites More sharing options...
105Speed Posted May 31, 2011 Share Posted May 31, 2011 OK so I may have come accross a 28/36 that needs some love, I have the adaptor to stick it to my std 997cc inlet manifold. 1) Will it make any difference to the performance of my (otherwise standard) car? 2) Are jets available for a 997cc engine? Cost? 3)Porting and polishing my inlet manifold, will it make a noticeable gain? 4) Anything I need to know that I have missed? 1) It will make it sound sportier and will consume more fuel and if you were really lucky possibly gain 2-3bhp. The power is all in the head on a pre-crossflow, you'd be better off having the head skimmed to up the compression a little and then doing some home porting on the inlet ports on the 997 head. Then you really need a cam upgrade too. 2) Yes, depends on where you buy them from NZ/AUS/UK Southern Carburettors in the UK will be able to supply you what you need. 3) No, but you could use the 1200 inlet manifold which is slightly bigger, the 997 inlet has two ribs on the main body of it, the 1200 is smooth, or ever better use the 1500GT inlet manifold but that will cause an issue with the exhaust manifold as that has a hole in the top of it which mates up to a core plug in the base of the inlet manifold. This forms a 'hot spot' so the fuel disperses evenly around the manifold. SO if you remove the original inlet you must knock out the core plug from the bottom, flip it over and stick it in the exhaust manifold to seal it. then secure it with a plate over the top to stop it getting blown clean out on the first fire of the engine. 4) Yes, you are wasting your time, money and effort. If all you want in your life is 48bhp of screaming death, then just fit a 1200cc engine from an Anglia Super or a MkI Cortina. Far easier than trying to squeeze 9bhp from the 997cc Then stick your 28/36 on that Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted June 2, 2011 Share Posted June 2, 2011 i whole heartily disagree with the pre-cross flow comment. when i slapped the weber (32/36) on my 18r the power increase was extremely noticeable, feels as fast as the gt familia i had which was 109hp and the 18r startd out at just under 90. at a guess it was easily over 10hp for $50, opened up my rev range an extra 1500rpm and made it a whole lot more slipery in the wet! i did do alot of research and knew the 32/36 was going to be a worthy upgrade as it was quite well matched. but i think if you can do alot of the work yourself, it can be quite cheap and quite enjoyable to play with.

Same carb upgrade is done on minis which has about same cc. polishing inlet side is a bad idear, has to be abit rough to help mix fuel/air. the only other thing is how to attach throtte cable. Good luck, planning on do upgrades on my big powerfull standard 997cc engine once body work is finished. Quote Link to comment Share on other sites More sharing options...

Was going to wait until I started working on it first. I have a house to finishes first. Which is very close, should be done in next couple of months. Yay. Been a very long build, about as long as my Anglia will take. Quote Link to comment Share on other sites More sharing options...
