Hi All,

It's been a while but I thought I'd give an update on the mods due soon.

Image

Its an early 525e block (11:1 compression) with a ported & polished M20B25 head with a few extra goodies.

Image

284/272 cam

Image

There's also some Ireland Engineering oversized valves but no photos. The head also has a 3 angle cut on the seats, new gaskets, seals etc.

For anyone else who might attempt this frankenstein engine I can confirm the valve to piston clearance is an acceptable 1.75mm even with the oversized valves, domed piston and fast road cam.

Image
Apologies for my sons plasticine

Some preliminary images of the ported head - Inlet
Image

And Exhaust
Image

Bottom end has been deglazed with new bearings, piston rings, core plugs, gaskets, timing belt tensioner etc. Crank was polished etc.

Block before any work
Image

Bare Block
Image

Block assembled with new bearings and graphogen paste
Image

Painted Block with new core plugs
Image

I've made a start on port matching the inlet also as I'll be fitting an M30 AFM and M20B25 throttle body.
Image

I'll be fitting M52B28 injectors, remap, E30 fuel pump and relocating the battery to the boot thanks to Gedzors rear strut brace. Had to make some minor tweaks and I'm having issues with the fitment with the Compbrake adjustable rear mounts but I'm sure it will all pan out.

I have also managed to bag myself a Fritz bits manifold to go with this and I'll be running an E30 oil cooler and Evans waterless coolant for longevity. Booked into a local exhaust fabricator also.

My plan is to have it complete and in early august in time for the Retro Rides show at Shelsey Walsh. Hopefully I'll see some of you guys there!
