How can these be fitted to A series in line engine as there is the oil pipe up bowl
@MEDEngineeringTechVideos 3 күн бұрын
Hi Peter, the Sprite pickup pipe can be fitted with just one tab, no problem at all.

It alarms me that you choose not to use a torque plate. Also, by "A" series, I suppose you mean a Toyota 4AEF or 7AEF?? Attention to details please!!

I have a MPI that has an original JCW Si conversion done, this is giving it 80bhp currently. If i install your stage 3 cam kit what improvement would it give?
@MEDEngineeringTechVideos 3 ай бұрын
You're almost at the limits of what the standard ECU will be able to cope with. You'll find more low-down torque with the performance road MPi cam, but have to be careful with emissions if the car already has a set of 1.5 rockers.

The SPi works really well with the HT and 1.5 rockers, or RS and 1.3s. Anymore than this and the ECU will struggle. With a lightly ported head and the above combination, you will go from around 63bhp to 75-80bhp.

@MEDEngineeringTechVideos 3 ай бұрын
The key to good performance on these engines is to optimise everything. So get the valves all cut to the same height, spring seats cut to give perfectly even spring pressure all the way along, and the rockers to give precise lift at each valve. Follow this ethos through the build and it will give considerably more power than a cobbled-together engine. In short, yes it will make a difference on a carefully spec'd and built engine.

@michalchlup6758 3 ай бұрын
I get the benefit of the rockers being directly over the valve stem, but I heard some time ago that rocker pushing only on one side of it also has a benefit - it makes the valve rotate which should help from carbon deposit only in some specific place of the valve, since it will sort of continuously "lap" itself?
@MEDEngineeringTechVideos 3 ай бұрын
It's an interesting thought, but the single collet valves typically do not rotate on the seats. Overall, these make a good upgrade over standard.

I'm thinking about all of this. I'm looking at a 948 Morris Minor, and I can't help but think how much better I can do with a modified crank, rods, and pistons. The pistons have a fairly tall pin height and skirt compared to modern engines, so I imagine a longer rod and a modern piston would reduce a ton of stress
