yup..... probably needs the head lifting to inspect after the layup, was always my intention to replace the 45DCOE's with throttlebodies (Hyabusa tb's & DCOE pattern adapters like I've made for the 1600 Mazda engine?) and supposedly for another project...... but the more I think  easier & cheaper NA power (200hp+) than a Mazda engine, should be easily fitted without loosing the possibility of reverting to the Mazda engine  also, something I already own needing little expenditure and no development unlike NA tuning a Mazda engine  Rich. |

How about the gearbox, I used a type 9 with and adapter plate.
A modded Opel Manta winged sump gave me the ground clearance and oil capacity. You won’t need that though.
You know it makes sense and I don’t know of another Mazda using that engine, can’t think why not.

How about the gearbox, I used a type 9 with and adapter plate I've been thinking of the Mazda / Asin 6 speed (now 5 speed?) that I've already got, admittedly I've not done any measuring as this is very much a new tangent and may not progress further.... as a basic conversion without Mazda's 'ppf' its easily done, to use the ppf is going to be more complicated but not impossible... A modded Opel Manta winged sump gave me the ground clearance and oil capacity. You won’t need that though. I've always viewed the manta 1.8 sump as a 'sorta' sump, good in it's intended fitment but not the great fit-all that people claim  that said, I've used a manta sump in a Chevette roadrally car (2L 8v Astra engine), mk2 Escort stagerally car (2L 16v Astra engine) and the escort needed bulkhead modification to allow the sump to clear the suspension crossmember interestingly, SBD have advised removing the exhaust side wing from Manta sumps to give clearance for exhaust manifolds - without engine reliability due to less oil capacity as to the drysump, recently oil capacity in reservoirs have been dropped to ~~ 3 1/2 Litres for engines with belt-driven camshafts (chain-drives habe more oil flailing around inside so need larger reserves!) You know it makes sense and I don’t know of another Mazda using that engine, can’t think why not. ha. I believe theres a few XE'd 5's around, locally there was one rallying a few years ago and possibly another competing at the moment, theres also a later Vauxhall 2.0L 'Ecotec' I've seen mentioned on fb somewhere...

had a looksee into fitting a Mazda / Mx5 gearbox to a Vauxhall 'XE' engine...  a Mx5 gearbox bellhousing compared to an aftermarket Vauxhall to Ford bellhousing. similar looking with startermotor position in similar position.  the Vauxhall bellhousing overlaid on the Mazda setup. as it's similar then curiousity means theres scope for an adapter-plate....  Mazda bellhousing offered up to the Vauxhall engine.  BUT the gearbox's input-shaft is not long enough to enter the Vauxhall crankshaft's 'spiggot' bearing (actually a Ford bearing as the fwd Vauxhall never had one fitted)  the Vauxhall engine design has it's flywheel closer to the cylinderblock compared to the Mazda design - hence the distance seen in the previous photo...  on a slight tangent, this Vauxhall engine has been modified and has a 'skeleton' flywheel to fit a 184mm multiplate clutch. so. I've a problem here, I could cut & weld a Vauxhall bellhousing 'lip' onto a Mazda gearbox, could go for a hybrid gearbox using the 6/5 speed I already have for the tailhousing (fit the Mx5's ppf & gearstick hole in bodyshell) and an Rx8 6 speed gearbox as theres adapter-plates available to connect various engines... more thinking to come....

Great stuff, you know it makes sense! must resist...... subject of.... I'm desperately tryin to NOT work on this conversion BUT just removed the camcover & this is what I found...  was expecting it to be corroded after ~15 years in a wet garage...  big camshafts, very non-standard, lots of duration & 11.5 lift (exhaust) 12.5mm lift (inlet) Rich. |

Bugger, more re-thinking & planning...
reserch into gearboxes time, anyone know for a dead Mx5 mk2 / 6 speed as this could supply a front case / bellhousing for adaption (or maybe an Rx8 item?)
hummmmmmmm...

recording engine dimensions...  Mazda B6 1.6L cylinderbock length 372mm.  Vauxhall XE 2.0 cylinderblock length 420mm.  in the garage I've a few engines, heres another 2 XE's  did some Google-fu and identified the cams in the XE...  Catcams 4600864 profiles in both inlet & exhaust so not mild by any means (OK I knew the engine was modified but after I'd bought it time ,circumstances & priorities changed so it's been almost forgotten - much like it's spec!) I now have timing details so can lift the head off the block, hope it's just going to be a case of evicting spiders  can see some corrosion on the port floor - why I'm lifting the head... I'm going to remove the /mazda engine & drop the Vauxhall in to assess its fitment, hopefully will not clash with any Mx5 steering or suspension components. more waffle to follow Rich. |
