washed it, also gave the underbonnet a rinse. then the moment of truth, would it start when soaked?  started as usual after a few compressions & idled perfectly   gfycat.com/GreenUnimportantAukyou can see the puddle in the cam-cover gallery, it's deeper than the base of the coils! slightly soggy  Rich. |

Will the t9 be a lot stronger than a regular mx5 6spd or is it for sequential reasons?

Will the t9 be a lot stronger than a regular mx5 6spd or is it for sequential reasons? think the t9 with straight-cut gears is good for around 250hp BUT they have a weakness - the main gearcase is cast iron and is known to fail* there are aftermarket aluminium gearcases that are stronger but I have no idea what the next weak-link is apart from the gears themselves  I have no intrest in sequential, it's hard enough to drive a conventional 'H' pattern and re-learning to drive is probably beyond me my intrest in the Ford t9 gearbox is the availability of diferent ratio's & clutches, as mentioned previously I'm looking at a smaller diameter (184mm) multiplate clutch for lower rotational mass as well as the higher grip (AND more choice of suppliers like AP Racing, Tilton, Scahs etc. - can be quite cheap for replacement parts!) Rich. *one of the mk2 Escort road-rally cars I used to work on had one fail on a rallcar after a full-throttle / top gear landing that resulted in the case failing and the front of the laygear dropping out of mesh & retirement. the car did have a 2.4L engine & sticky road tyres (Avon Turbospeed CR28 Sport) and was a contender to win the rally |

Ah, it is an interesting exercise in engineering. Following with interest.

So, lastyear I bought a Jenvey inlet manifold with the intention of possible throttlebodies fun... today I bought a pair of Weber 40 DCOM Carburettors to adapt as throttlebodies   another ebay error maybe but from the photo's & listing they are new in boxes / unused so shiney at least. why carbs as throttlebodies you may ask? well, Jenvey (& Webcon) based their TB's around Weber's icponic DCOE series but removed the carburettor stuff & fitted injectors, I'm intending to seal the bodies & fit injectors in the manifold as luckily Jenvey cast suitable bosses there so a little drill / milling operation or two will sort this  also, these carbs were a lot cheaper than a pair of Jenvey TB's and similar priced to a set of bike TB's so no real contest. if they look to be a lot of work then I can re-sell them & sort another setup *luckily* I have a webcon throttle linkage & 4 'rampipes' (trumpets) for 40DCOE carbs in 'stock' from an un-started build on someone else's car (1963 Lotus7 1500Cosworth) so things are starting to come togther Hopefully....... And... ebay again. so, I decided to buy a cheap eps column & have a lookse.... HYUNDAI I10 eps column on ebay for the huge sum of £29.99 posted hopefully it will be as in the photo with the control-unit & driveshaft / universal-joints as the uj's will make adaption so much easier   I've chosen this as... 1, its cheap so not a huge loss if it does not look like it will work  2, it looks like it's small enough to easily fit in the space available? 3, it's not a Corsa column - the corsa 'b' column's are commanding a premium price as they have been the mainstay of EPS conversions forever & are now getting somewhat screar canoe compared to a few years ago... Corsa 'C' column's are cheaper but can have issues as they are mostly 'adjustable' with a coupling in the shaft so not so easy to adapt? 4, because? luckily I have a spare '5 steering-column so can make a jig for the mount positions & maybe 'borrow' some parts  now waiting to see what gets delivered Rich. |

Re Weber conversion to TB’s, I did exactly the same thing years back, will try and dig some pics out, also made an inlet manifold out of the 2.0xe manifold to match the ttb’s
I milled vast chunks off the Weber’s, but it worked.

I remember reading about the 'conversion' in CCC probably 30 years ago (not your car but something in 'Walkers Workshop' or whatever ) I've made a few manifolds, 1'4" steel for the faces & suitable tube (exhaust?) shaped for the runners. think I've still got some head-plates for Vauxhall 8V/2L in the garage from 15+ years ago when I was interested in that sort of thing  bring on the photo's, "we want information".... (said the new Number 2?) Rich. |

more ebay sillyness I've always disliked the route Mazda used for the lower radiator hose (okey, I understand it was standardisation for aircon pump clearance). but as my car had aircon removed before I bought it theres no reason to have the hose close to the exhaust manifold when theres plenty of room to reroute away from heat... so, ebay and looking at other things I tripped over the shape of the Lower Radiator Hose Water Outlet Elbow for Mazda 323F. part number B6BF-15-161 , found a seller in Cyprus that has new items for £16 posted (possibly plus import? will find out also, will UK Mazda dealers supplu for similar prices??? )  basicly aims straight out of the waterpump & has the port to take the metal heaterpipe so no further modifications. next to look more into diferent radiators, thinking 90's Polo and an expansion-tank system Rich. |

been diggin..... I had (somewhere) a Webcon twin-cable / lower mounted throttle linkage for DCOE type carburettors  also 4 off Weber rampipes for 40DCOE and 6 off 45mm Jenvey rampipes (fit Jenvey throttlebodies, Weber 45DCOE & Delorto 45DHLA carbs )  so, if I remember correctly, a 40 DCOE (& maybe DCOM?) carb with no aux venturi's or choke-tubes has an airfilter-side bore of 45mm, if this is correct then the jenvey rampipes can be used on 'empty' DCOM carbs used as throttle-bodies hopefully more bits coming togther Rich. |

EPS column stuff... mighty5s.com/thread/3163/eps?page=1&scrollTo=39642also the 40DCOM Weber carburettors arrived, now to sort converting to 'empty' or dummy Throttlebodies so... sorta fit.  BUT the carbs have longer throttle-spindles than Jenvey make to suit the 1.6 manifold  the angle that Jenvey make the throttlebody manifold to give clearance in an MX5's engine-bay (clutch master cylinder is sorta in the way on RHD cars) as I have horizontal carburettors they would not realy like to run at this angle efficiently not a problem using them 'empty' as throttlebodies and fitting the injectors in the inlet manifold.  into it's mouth, on the left are the carburettor's 'aux-venturi' & 'choke' tube, these are for the 40mm bore size. on the right I've removed them to show the 45mm bore that steps-down to the 40mm diameter of the throttle butterfly  more thinkin to be done Rich. |

so, after some thinking.... the Weber carbs will not work as I want, partly due to not wanting to chop up a new pair of carbs & partly due to their 'mixture-screws' (would have been used to ballance the throttles / as air bypass for tickover) are inline of where the injectors would live IF I use the bosses cast into the Jenvey manifold  so... plan B (well, plan B on throtlebodies anyway...) trawling ebay, looking at bike throttlebodies.... Triumph Speed Tripple have keihn individual bodies that house injectors post butterfly only problem is that there are three and I will need 4   so, a few 'best-offers' later & some were bought, one complete set with trumpets and one complete set without as annoyingly most breakers remove the trumpets (ram-pipes as I was taught) so I need to find a single to make the set when they arrive I will look into altering their centre-distance & making spacers / finding bolting to secure, also altering the throttle-spindle's 'ballance-linkages' to connect the seperates... then design & machine adaptors to mount on the Jenvey / weber manifold face. as a temporary trial I'm tempted to run these on a standard Mazda ecu but will need to 'trick' it into thinkin that there is an airflow-sensor operating (air-mass consumed is easy enough as it's a potentiometer in the sensor BUT theres also a fuel-pump deadman that needs thought - maybe relayed power feed triggered by oil-pressure or alternator output ) also, been playing with more EPS stuff Rich. |

Next... another consideration on Mazda's design of the '5 was the waterpump's coolant outlet to the radiator & heaterpipe as this sends the pipework near the exhaust manifold... I had intended to fabricate a replacement flange & pipe to aim foreward but I remember seeing a diferent shaped flange on the 323 cars (I used to work on & service a 323GTX rallycar) so ebay again and a new / old stock item was on the way from Cyprus    as you can see theres a bit of a shape diference! also, the diameter of the 'stub' that the flexi-pipe fits is a few mm smaller on the 323 item with the heaterpipe connection in a slightly diferent place also theres no metal pipe-stub for the thermostat bypass (although these shouldn't be an issue for me as I'm re-designing the cooling system & fitting a 'twin-pass' crossflow radiator that hopefully will be more efficient than the Mazda design huge item ) waiting for the radiator to arrive now, then the fun of making it fit and plumbing with the added extra of deciding on shape & position of the 'expansion-tank' that's needed for this setup fun. Rich. |

I used a Vauxhall Bosch motronic Ecu when I ran dellortos on my Westfield, fabricated a “box” that went over the intake trumpets, it had a single air inlet via the original AFM (I know it restricted airflow!) and also put the original TPS onto the carb spindle. It worked well, don’t ask me about power, I never dynoed it, but as an experiment it was fine. Have pics somewhere.... also used the original dizzy and coil, so basically the Ecu ran the ignition and the fuelling was via carbs.
