IMHO this project would make for a very bad road car. I mean bad bad, as in rubbish bad, not as in wicked bad which might mean good (or even cool?), oh crikey I am too old for all this modern slang stuff :paperbag: Conclusion = race it! :driving:

I will just mention it in passing that whilst everyone is aghast at the price of the Toyo R888 225/45/15, the price for a 215/50/15 is half the money! Camskill will do you a set for about £410 delivered and looking at the Toyo specification sheets the overall width of the tyre is very comparable to the 225 width. The only downside to me is that the tyre is heavier but for any track day user that should not be a concern. Worth looking into guys!

Anyway my real reason for posting today is to say I am pleased to have found an anti vibration mount for my fuel tank. Last thing I wanted to happen was having built a great tank for it to crack up as it was too rigidly mounted. I have found these

http://www.polymax.c...ded_Mount.shtml

and I think they should fit the bill perfectly.

Other news is that I spoke to Jenvey today and was told that the production of the inlet manifold is coming along well. The first one was being machined today and then to be tested over the next week or so. I hope to have mine this side of Christmas.

I am switching ECU plans from Emerald to DTA. I am now planning on running the DTA S80 ecu which will give me more toys to play with :whistle: plus it also plugs straight into my dash/logger system. I think it a more race orientated piece of kit that will meet my needs better so not knocking the Emerald at all, its just a horses for courses thing. ECU web link is here:

http://www.dtafast.co.uk/S_80_PRO.htm

So with ECU, tyres and inlet system being bought very soon, Christmas will be coming early for me! Also beats the bloody VAT rise.....

Cheers for that Malcolm, I may have a look at the 215/50, I'm guessing the extra height will alow for the bit of stretch... and for me at my level I'm sure it will be plenty grippy enough!!

Good news that all the other bits and pieces are coming together, so who will be doing the mapping for you?... and more importantly for all of us watchers... when!!!

DTA is a much better choice than Emerald. May I just say though that if data logging is something you will want to do then, IMHO, the much greater cost of Motec, is worth considering. Data logging is second to none for such an ecu, with exemplary support. Along with it's amazing re-sale value, it makes Motec worth the extra. Most of these ecu's will do as much, if not far more than you will ever need, it's support and data logging that you pay the extra for.

I agree that Motec stuff is great but already have the Race Technology logger and dash. We have used Race Technology stuff before and it is ok and is fine for my level of driving. The switch to DTA however will give me a gain in performance, or at least that is my expectation! There are DTA specialists out there with rolling roads who will set the car up for me. When is a very good question.

Looking very good indeed Malcom. B)

If you wanna make double sure on that rear bumper you'll find a perfectly positioned hole in the rear panel, directly above the centre tab on the bumper skin.

See about 2/3rds down this page:

http://jasonoshart.w...26/monday-26th/

For the effort and weight involved might be worth doing?

With mine like that I've never had any issues with it at all - after three months use it's still on tight.

Hi Harty

Looked at your solution and I think that we have done the same sort of thing with minor design detail differences. Good to hear it is still working on your car so hopefully will stay that way on mine too!

Went to an Abingdon airfield track day today. Its been a long time since I drove on track so thanks to Jon for letting me loose in his Mk2 Golf. Great fun. Nice to chat to some chaps with a red MX5 NA, quite standard except running full on Dunlop Slicks. Would be very keen to try some of those later on.

Following on from the chat on tyres, Mark (Jibberingloon) from NCB Motorsport can do these tyres cheaper!! He is really competitive on the motorsports Toyos.

Have you had any thoughts on wet weather tyres? I'm assuming you'll have to have some?

Wet tyres are just unused R888s unless there is standing water or monsoon conditions. If the latter conditions exist then I have a set of regular road tyres on 7 inch rims to whack on. Whilst this is England and it rains a lot, actually I have had way more damp or dry races than ones where I have even needed to comptemplate switching tyres.

I have now placed an order for lots of 215/50/15 Toyo R888 from Jibberingloon at NCB Motorsport plus some other stuff (more on that when it arrives) so am pleased to report that NCB Motorsport were the best priced supplier I could find for R888s and I found Mark and his staff very good to deal with. :thumb-up: from me!

I have just been sent some automotive porn which I think you should all should see! Only a couple of pictures but I think you will like.... :drool:

Ok, here we go!

Today I had a good chat with Simon from Jenvey who has my inlet manifold and TB set sitting on his desk! :woohoo: He has sent me a couple of pictures of what Jenvey are now offering as a standard kit so this is available to all and sundry from now on. And the great news is that there is a kit for FI cars as well as NA cars.

The first picture is of a NA kit on a 1.8 development car.

Posted Image

The air horns are 40mm air horns to obtain clearance from all the standard bits you find in the engine bay. Because I don't have anything to worry about in that regard I will be using 90mm air horns to gain a bit more power etc. :whistle:

For you FI guys Jenvey have made this set up

Posted Image

Not being an FI chap I don't know how this compares to a typical set up but the injectors go in the inlet manifold instead of the head which I beleive to be an improvement and also the plenum chamber is designed for FI rather than a NA one converted to FI.

Cost wise both kits will be £611 plus vat and include manifold, throttle bodies, fuel rail, and air horns. Also included will be the plugs to bung up the injector ports in the cylinder head. For us NA chaps, the TBs are 45mm bodies and are good for flowing for 250 bhp.

I weighed the OEM full induction set up on my 1.8 engine and it came in at about 12 kgs. With this set up I am expecting about a 75% weight loss item for item. Works for me. :goodjob:

Some other developments that Jenvey are working on include doing a 1.6 engine set up in the near future so don't feel left out if you have a 1.6 over a 1.8 engine. I also know that Jenvey are working with OMEX the ecu guys to do a complete package of inlet system (as above) and ecu electronics to replace the OEM ecu so no more piggy backing ecu's. Don't know the cost of that yet but I am sure if you spoke to Simon at Jenvey he can guide you as to the latest developments of that package.

Oh and one last exciting this..... If you are a Nutzer or MX5 OC forum member, Jenvey will give you 10% off the prices I just mentioned above. :goodjob:

I doubt any of this has reached the web sites of Jenvey or Omex yet but links to their pages are here

Very pleased these bits are coming to me soon :driving:

Cracking stuff, certainly looks like well made kit at a decent price from Jenvey as ever...

Only concern on the FI stuff. I used to have a TB's and FI'd setup before on a Pug 106, and it was a nightmare to setup and get drivable.... the throttle was VERY sensitive due to opening 4 TB's instead of one all at once, made slow speed driving hard to modulate the throttle on.... Looks nice though! ^_^

I would say you have it right Jon, a single TB for FI applications.

Great news about ITB's and seriously capable price! That quality looks great!
Malcolm you said that you will be using 90mm air horns? How will the #4/closest to brakebooster fit? I had maybe 20mm space between the horn and brakelines in my fuji racing ITBs, you dont have brakebooster?

Great stuff, really interesting news and some great pics... I'm watching this with even more interest now!! :popcorn:

I'm tempted by the idea of a Mk2 1.8 engine transplant with a bit of headwork, some cams and this TB setup... nothing too over the top, but it should get decent power, certainly way up from my 116!!
Saying that, I'm also looking at a Rotary conversion, or a V8... or maybe a 2.3 Duratec... you get the idea, too much time and not enough money at the moment!!!!!
