Efi Supercharged Blow Through
Turbo Mini Forums

Hi all I've been registered for year but never posted a topic but now I think its time to show the progress and giving you an idea of how I'm converting from carburettor to multi point. So after hours searching on the forum trying to understand the problem in injecting an a-series engine and trying to find the best ecu that will work on a 5 port head, I came with a conclusion and bought a MS3X from Extraefi. As for injector I'm using siemense deka, two 480cc for primaries and two 875cc for secondary's.
The engine is 1275 A+ with omega forged +20 pistons, H section rods, standard balanced crank, med light weight non verto flywheel assembly, med rs camshaft, 1.5 roller rockers, ported and polished head, straight cut gears and the supercharger is a m45 mounted at the front of the engine.

This is the setup with the carburettor sorry for the poor image.

Sounds like a nice setup.

I presume it’s a clubman front end?

Its a steel round nose flip front but with 3 inch extra

Interesting looking project. Did it work ok on the carb?

Interesting cam sensor.
Hall switch I presume from the three wires but what is it looking at on the sprocket ?

Schrödinger's cat - so which one am I ???

Hi it worked well on carb but you now you always want to improve something
For cam sensor, yes its a hall type and its seeing a higher head of one of vernier cam sprocket locking bolt.
I want to ask a question how can i host pictures from google photos because when I put Img in square brackets at the beginning and at the end of the url the photos are not displayed in the post?

So finally I got hold on how to host pictures from google photos and now I can show the progress on the intake manifold.
Basically the manifold will be a dual plenum and here are a couple of virtual shots









And here is the progress in reality

First i started with the two runners, from a peace of solid aluminium block like this



after days using a chisel and hammer I managed to finish the two runners.





These are the trumpets

Here is the custom fuel rail







The runners, trumpets, injectors and fuel rail all together for the first time.

That's some nice DIY.

Impressive!

Someone stood at the mill a long time doing those pieces!

Where are you located? I feel like I've seen this mini before?

this looks like the install that was in the mini that JohnySTI used to have, it wasa Vmax blowthrough prototype IIRC.

Hi a little bit more update, here are some pics of the runners in place and cardboard model of the plenum just to have an idea of the clearance between the bulkhead and plenum.

Hi a little bit more update I've started to build a part of the plenum which is this



and this is the progress so far.

Nice build

In the 13's at last!.. Just

Hi today's update. After a little bit of grinding, polishing and adding an end plate the part ended like this.

Hi today I thought that I should also show some photos of the interior.

Hi a little bit more update, today I've finished the throttle body flange, its made from 10mm aluminium flat bar. The throttle body is from a renault megane, it has a 4 wire stepper motor for idle control.





And here is the flange

looking great so far!
