Road Runner SR2 build

Get those felt tip marks off asap as they will stain the gel coat.
In your case you may well be cutting that material away so not a problem but as a rule it is best to do any markings on masking tape.

Slow month due to working on other projects... as you do!

I've taken the engine back out to do some work on it, my sump has been sent of to be chemically cleaned along with the baffle plate, since coming back i've primed and painted it.

Im replacing the standard mx5 crank pickup points for a proper 60 tooth trigger wheel, its been sent of to the machine shop to fit perfectly on the back of the pulley.

the centre console is fitted, although I still need to put the gear surround on. after this the side panels will need a final trim then they can be finally fitted for pictures!

I've fitted some heat matting to the other side of the battery now the engines out.

Also fitted a core plug to the back of the engine for the coolant re route.

then some general cleaning with the engine....









scrubbed the inside of the gearbox, fitted new release bearing and slave cylinder

I've seen the car in the mag and in the flesh at Autosport in january... very nice car!

[petrol head ash]

lots of little jobs done over the last few weeks...

fitted the engine back in for the last time, front suspension etc all fitted.

Also painted the manifold and down pipe in heatproof paint, I will look at getting it cam coated soon but I'll need a cat for IVA so won't do it until I know it will pass emissions and noise.

I've purchased an intercooler, Im going to mount it underneath the top bonnet vents then hopefully in the future fit a fan underneath the intercooler that activates when boosting. The intercooler isn't permanently fitted yet but roughly sitting were I'll mount it.

Cut the whole round the supercharger, this will need a final trim to finish off then the outlet pipe will need painting.

I bought some 'D' shape rubber to lift the rear panels level with the rest or the car, it also gives it a slightly more finished look. The centre panel in the pic is slightly lower due to panels placed on.

Fitted an inline high flow fuel filter in the back... you never know with supermarket petrol!

Hopfully the engine will fire into life within the next week...

I've ordered my ECU, I had plans to fit Emerald or Omex as I've had these on previous cars but since talking to 'Canems' at Autosport my mind was made up. Any questions I had were answered with no worries what so ever. Also, out of all the different companies I spoke to (Dave, owner of Canems) was by far the most helpful, and to top it off he had already done a supercharged mazda setup.

Still need to do some finishing here but its mostly in place, the plan is to fit everything, make sure everything is ok then after start up do some final finishing/tidying.

Next is the water pipes,

Also front indicators in this pic...

Theres one more water pipe to fit then a few vacuum pipes..... then... hopefully I can turn the key!!

I couldn't resist pushing the car outside for a few pics...









The car looks nearly finished here but theres still a long list of lobs to do yet.

Looking good.
May be worth checking your front flasher position as they look to be more than 400mm in from the edge of the car. The rear wings are likely wider than the front so that is the dimension you must use. Also check that the flasher can be seen from 80 degrees outwards and 45 degrees inwards. I think your current position will fail on the inwards as the nose will be in the way. This may be resolved if you put them on stalks to meet the 400.

Stunning work Ash! Dose the intercooler get its own air feed or is it air thats already been throguh the rad?

[Furyblade_Lee]

That is really really nice. Well done!

[petrol head ash]

Thanks for the nice comments, I've really enjoyed building the car and hope to be track daying this year!

Thanks steve, I have looked into the front indicators but others have passed with no issues so I think I'll leave it for now then when I take the car back to RoadRunner for it's suspension setup before IVA I can look at it then, see what they recommend.

The intercooler will have a fan underneath to pull air through, then an aluminium plate from the top or the rad to the back edge of the intercooler to reduce heat soak. If it works I don't know but it was the only way I could see it keeping the charge as cool as possible... unless its fitted at the front but its pretty tight under there and I didn't want the long pipes, plus, I quite like looking at the intercooler from above through the mesh.
The same engine in the Mazda made 200BHP so I'm hoping by running a stand alone ECU and an intercooler I hope to achieve 220. but to be honest Im happy with 200BHP! Its just nice to say I've got a supercharger when filling up at the petrol station, most peoples jaw dropped when I said I had a 2.0l in my striker! Funny really.

[chuntington101]

Ash have you concidered using a pusher fan under the intercooler? Just thinking the vents in the noce are probably in a low-ish presure area and it will therefore be easier to push air through the intercooler and out the top and pull air in the top vents?...

[MG CHRIS]

That's looks stunning may be tempted do build one, not a big lover of 7 reps but that is very nice especially in orange and black.

Keep up the work.

I can see what you mean but I think I'd be a bit concerned what the engine bay temperature was getting pushed through the intercooler? although the heat from the rad will hopefully be ducted under the cooler I thought the colder air from outside the car (through the vent) would be better pulled through?...

...but, this will be a future mod, just something I thought about to get the most out of the motor.

Great build Ash, been following this one with much interest since a colleague is considering an S2000 powered SR2. He is currently in talks with Mike regarding the modifications required to take the Honda lump over the more traditional Mazda engine. As for myself, this is looking a likely candidate for building to commence in about 2-3 years' time. It just looks so purposeful, and the inboard suspension system is just a work of art! Good luck with the remainder of the build.

Hi, thanks for the compliment.

The S2000 engine will be such a good setup in a light weight car, I almost decided to go that way myself at one point but couldn't turn away the supercharger. I don't think there will be much trouble getting the S2000 engine in the SR2.... Mike's a great fabricator, he managed to get a V8 in there so the Honda should be a walk in the park!

Ash what v8 did mike fit? Would love to see a GM Ls engine in something like this!

[jeffw]

I'm not sure how effective that intercooler will be. If you pull the air up from the nose it will be heated via the radiator and, as has been said, the top is a low pressure area. I guess you will need a scoop to make it work at all (like an Impreza).

GM LS1....

406hp, 425ft lbs, bit of internal tweaks running a Canems ECU, engine built by Tim Adams Racing engines,

T56 gearbox..... I Love it, I want one!!





The second 'nutter' put a LS2 in his car, I saw the cars when I picked up some parts... The green car sounded amazing....
