Hi guys, yip I was at Euro central last month. Missed this one, due to being at my mates wedding on track a knockhill. Car is wrapped apple green. Been done for 3 years now, starting to fade bubble & rip. Time to tidy her up & paint her now she's being retired from track duty.

Cheers John

Spoke to him at fordfair this year. I'm a bit of a pain & like to have a go at doing things myself. But have his number in the emergency dial list.

I read that the VAG engines apart front some V8's all have the same bolt pattern. I was considering fitting a VR6 engine in my sierra as the MT75 has been mated to the VAG 20V before in some kit cars.

Think your right rob, from what I've read any way, all the 4 pot engines have the same bolt pattern.

Got the engine sitting in its final position. Took all measurements from the gearbox on my other rx8 & sat the head on to see where I stand with the bulkhead.



Cut pipes & sound deadening out the way.



Cut out some of the bulkhead, I'm going to have to remove the dash & see what I can do with the heater. Don't know if I'll have any room for it. Need to cut back a bit more to get the engine where I want it.

Decided it was time to strip out the beautiful interior. A job I really wasn't looking forward too.








May have to sacrifice the heater unit. It's massive.

Cut some more out the bulkhead to give me more room.


Inlet now on.


Exhaust manifold on. This won't be the one I'm using, have one with the turbo further forward.


Even enough room for the cam cover now.


View from inside. No need for fancy gauges. Passenger could just lean forward & feel inlet & exhaust temps.


Bonnet even closes.


Cheers John

Plenty of room for cam belt changes that's for sure.

These engines have coil packs mounted on each cylinder if memory serves correctly. They are prone to failure if they get too hot. Can you remove the rear most one with the engine in situ? Looks really tight!?



Cool project though, looking forward to seeing the result

Well coilpack, was a bit of an oversite. But after much head scratching, I've come up with a plan. With the cutting done, you can see the coilpack under the scuttle panel. So after its all welded back up, I'll leave an inspection panel to change the coil pack. Meaning you have to remove the scuttle (a couple of screws) not idea, but better than removing the engine. Well spotted, saves me a headache in the future.

With all that, I didn't do much else. Sat the standard strut brace on to see how far back the engine sits.


Could even put old engine cover back on.


Cheers John

Cool project. Couldn't you just mount the coilpack elsewhere?

It's on plug coilpacks on this engine. Should be all sorted now.

Yip, coil on plug. All the 1.8 20v turbos are.

Being a relatively modern engine, I don´t think you would need to change plugs that often unless you install crappy ones or run out of luck.

I have yet to change plugs on my tintop and it´s now 80000 km.
Manual states spark plug change @ 100000 IIRC...

But a fair point to consider.

Remote mounting the COP shouldn´t be a problem either.
It was the way engines were built back in the days...







Beware of what you wish.. for it may come true....

Nice project, to be watched with some interest.

A colleague had an RX8 a few years ago and I have to be honest, it was a disappointing car to drive fast - rather numb and never felt like it had any real oomph to it.

That's my main reason for doing it. Out on track in the corners , they're great. But get on a straight & you're done.

Hope to get some work done over the weekend, steel to make the adapter plate comes on Wednesday. D

Sorry guys not had much time to spend on the car. But managed to get some time during the week to make the adapter plate.


Made the new bulkhead this weekend. Have left a removable inspection plate, to allow access to the rear of the engine.


Should be enough room for the engine now.


Plan of action for this week is to get engine back in with proper plate, make engine mounts & take final measurments for flywheel.

Hope to keep this post moving & updated now.

Will update time spent ASAP.

Cheers John

Got the drivers side mount tacked up.

Mock up engine in, sitting on its own mounts. Still have proper spacers to make to replace washers.




What do you think so far guys?

Good work. Plenty of room for a big fat intercooler in front of the engine.
