Regular Posts: 280 Location: Nottinghamshire/Derbyshire | I have been toying with the idea of putting a 1600/1800 16v into my car, so bit the bullet and went for it. My good old jock friend also convinced me to go bike carbs in the future (he is a genius with megajolt and r1 carbs having done many conversions) so here it is.....I will update the progress so far when I get time away from work. Enjoy | ||

New user Posts: 7 | I'm the Jock mentioned above,keep waiting for metalmnan to update this thread, he has'nt so I will. Donor car, a badly abused MG ZR, but the engine had been rebuilt by a mate of mine a couple of years ago and hadn't been used much since the car had been crashed into a streetlamp, so we got it running and it ran sweet. Engine was looking scabby, so it was cleaned up. | ||

New user Posts: 7 | tidying the engine. It was treated to a new cam belt and vernier pulleys, these will help optomise the cam timing on the std cams just now and will really be needed when I get the spare head ported, ready for some fast road cams when the R1 conversion takes place. Here's the car. In all it's 1100cc glory. Bye bye 1100 The bolts holding the engine mounting bar had badly corroded heads, these were replaced with ones. 1600 flywheel was sourced and lightened. Lightened flywheel and old std one. 1600 fitted. | ||

Regular Posts: 280 Location: Nottinghamshire/Derbyshire | We think we have traced the running problem to a duff pump...will put pics of fuel pressure gauge up soon...will change pump and see what happens. | ||

Regular Posts: 280 Location: Nottinghamshire/Derbyshire | so..as a long overdue update to this. I had a custom manifold made. A few pics are below. The workmanship is unbelievable if I'm honest. Edited by *metalman* 17/2/2016 5:33 PM | ||

Regular Posts: 280 Location: Nottinghamshire/Derbyshire | And here are some of the manifold fitted up to the car... The real money shot! Its starting to look like a car again instead of a collection of parts. After this I decided to mock up the carbs onto the engine (excuse the poor fitment, I will be using proper R1 carb rubbers to fit them) | ||

Regular Posts: 280 Location: Nottinghamshire/Derbyshire | Since the manifold was now in place (held by a top secret rubberised compound - no gasket!), it was time to move on to rebuilding and rejetting the carbs. Step 1. Flip the carbs upside down and remove the underside of the float bowls. Step 2. Inspect. Dirty and full of crud! Step 3. Remove main jet (the slotted bit on top of the big hex) Step 4. Make the main jet bigger! Step 5. Refit enlarged main jet. Size depends on engine size and state of tune. Edited by *metalman* 17/2/2016 7:08 PM | ||

Expert Posts: 4458 Location: Jelling, Denmark | your new mainfold looks great but doesn't seem to have the small waterpipe at the cambelt end, will this be a problem? | ||
tom reid |
| ||
New user Posts: 7 | The water pipe fitting was not on the manifold at the time the pics were taken, it is now though. | ||
*metalman* |
| ||
Regular Posts: 280 Location: Nottinghamshire/Derbyshire | As Tom said, the manifold was fabricated without the small water pipe fitting,we added this before fitting the manifold to the car, so it all functions as intended. | ||

Elite Veteran Posts: 931 Location: west bromwich, birmingham | joshmk4 - 18/2/2016 6:55 AM One thing I've never done nor been advised to is drill out jets, that's all a bit silly haha,nice build how ever though done it several times over the years need good drills and a lathe to do it right, how it works ifjet is a 100 that is 1mm hole center so if u needed a 170 jet you would need a 1.70mm drill and so forth ect Alex | ||

Regular Posts: 145 Location: Lincolnshire | Makes sense, but different Carb manufactutes use different number ratings, seems a ballache calculating it? | ||
*metalman* |
| ||
Regular Posts: 280 Location: Nottinghamshire/Derbyshire | Having a good set of small sized drill bits works wonders. I have driven a couple of bike carb cars that have been done this way and I can assure you they respond very well. It may seem pikey drilling jets but it works. And as above, the induction roar is like nothing else. | ||

Elite Veteran Posts: 697 Location: leigh | How are you going to control the spark? | ||
*metalman* |
| ||
Regular Posts: 280 Location: Nottinghamshire/Derbyshire | Spark is controlled by Megajolt. Uses a Ford coilpack and edis and you can map the spark to whatever you like. Edited by *metalman* 2/4/2016 2:01 PM | ||

Regular Posts: 280 Location: Nottinghamshire/Derbyshire | Anyway. To crack on with the rebuild.... Step 6. Remove Idle jet. Step 7. Redrill idle jet a tad larger. Step 8. Refit idle jet. URL=http://s122.photobucket.com/user/turkey666_ak/media/received_10154015531710628.jpeg.html] Step 9. Lots of cleaning! To go from this: To this: Step 10. Refit float bowls. Step 11. Flip carbs over, remove plastic top and start to check the springs and needles. Hang on. This spring looks a little shorter than standard. (More on that later!) Step 12. Remove diaphragm and check for dirt/grit. Looks pretty clean, it wasn't! Step 13. Remove needle from diaphragm body. Hang on, how many grooves are on top of the needle? (we are almost there.....)
