I agree there as our car is quite scary at times.

Took the car out today to get a bit of sun. Seemed a shame for it to miss out!

damnn.. that's looking fine :p
rather inspiring :)

i don't know if it has been mentioned already but just out of personal interest, what inter-cooler are you planning on using ? :)

Michael

Not sure what type of intercooler im going to be using yet, Probably a custom one.

Here is a little update of some bodywork. I have a load of work to do on the MNR nosecone and it will look alot different by the time its done. But that is the current length it will sit on the chassis.
Got a bit of a overhang on the scuttle. I thought i was going to have to pull it out now it seems i have to push it in a little lol ops. Anyone know the exact location the scuttle should sit and how much it should overhang the chassis rails?

The MNR nosecone is an odd thing - it doesn't look good in photos, but looks fine in real life.

It's probably a good idea to use a nose with a lot of air through-put - you'll need all the cold air you can get! (don't forget to give the air somewhere to get out again).

This is a fine project... :)

Indeed the mnr vortx race nose is a strange looker thats for sure. But the reason i love it is that its so tall and it will clear the front of my engine (just). The air will be split into two sections 1 (top) for intercooler and vent out of the top of the nose. 2 (bottom) to go into the radiator and two oil coolers some of this air mainly from the oil coolers will exit via the little wing bits.

Oh and just because it looks funky!

Reminds me a bit of the Xenomorph from Alien.

TT

I'm back! Due to all the moves working on the project has been hard but have not got access to an unused 60000 sq ft unit that I can use. So will be getting the project started up again! A friend offered me cash for it and made realise how much I don't want to let it go.

Anyhow will keep you all updated with progress!

Welcome back Alex....been a while:rolleyes:

Welcome back
 

What he said!

Good deal, glade to see your going to stay with it. Your build is one of the more interesting & well done builds. Here in the States there's a saying "Dare to be different".
I especially like your choice of power plant. It can't help but be a beast. I always found powerful cars to be more fun and challenging. Will be following your Turbo installation & tuning with partecular interest.

Good Luck & Keep the faith.:D

Roger

Thanks guys!

I need to make some sort of plan so I can crack on and get things done.

Right my mission is to get a floor on and chassis painted. To do this i need to do a few things...

• Make/fit light stalks.

• Plate under steering rack area (think will help stop stuff hitting front of engine while driving)

• Figure how to mount pedal box

• Fit pedal box

• Figure out how to properly mount seat rails.

• Fit seats

• Build steering frame in cockpit area to fit granada gear

• Build/Buy/Fit fuel tank. (With mounting brackets)

• Design and build a system for fuel/break lines

• As above but for wiring

• Paint under side of chassis ready for floor fitment

• Fit floor (will leave propshaft area with no floor)

That should give me quite a bit to do.

Welcome back Alex,

Its great to read that your build is to continue :cool:

Will watch your build with great interest ( as always have :) )

cheers

Nice solution to my cooling problem....
http://www.grsmotorsport.co.uk/westfieldcustom.html
Only problem is the Supercharged Duratec engine puts out less heat than the straight 6 skyline lump. So might need it modified to be a bit thicker. Unless you guys think that one would do?

That looks very nice indeed :cool:

I have no idea how much heat your straight 6 will create but if you were to use that rad then how about making the side panels either side of the engine bay flared out to allow the heat generated to escape & improve the air flow thru the engine bay? just a thought :)

cheers
andy

As you say may need to be a touch thicker, depends what power you are going to run? I dont suppose a standard mr2 turbo intercooler is any bigger than that capacity wise and they manage ok in a mild state of tune

You could always fit water injection if you get heat issues

OUCH that radiator and intercooler is £700. That would pay for alot of kit for the car

power would be standard would also be running two oil coolers so that should help a bit.

The power of the engine has a direct bearing on the cooling needs. If your engine knocks out 200hp it will make the same heat and require the same amount of cooling as a four pot of the same hp rating . All you need to find is what others have used to cool the equivalent. Convert hp into kw and thats your cooling needs. Any decent rad company should be able to advise on that.

Bob

Interesting. Thinking about it my one would be slightly different. As would be running a larger intercooler and a different skyline GTR plenum. Power would start at around 245 ish upto around 280.... ofc can push it right upto 500ish if wanted rofl but chassis would suffer i think.

http://www.ebay.co.uk/itm/MAZDA-RX7-...83911117022469 Possible intercooler that will fit :D

Have you looked up mr2 intercoolers?

They are small and fat, may do the job

After a load of research and a quick chat with Red16 from passion ford.
Have conculded the best option would be.........


RX7 FC3S
16" fan
Civic Rad 92-00

Pics from Red16's build




My only real worry is the fact that the civic rad might not be able to handle the load form the RB25DET. Not sure what i can do apart from possibly install a 2nd radiator somewhere or two oilcoolers to help bring down the temps a little.

I would of thought the rad is never going to get cool air mounted like that, you may need to duct air into and out of it. Neat looking rads though

Found ths article and it refers to a water to air charge cooler, never heard of or seen one before but are very compact. there is one at the back of this engine.

Bob

edit found this one which is good for 300 hp http://www.frozenboost.com/product_i...39391500bf49d1

here is the charge cooler I am going to use

The celica gt4 (94/99) charge cooler can handle a good amount of power for its size, its a common upgrade on the mr2s when you start going towards the 400bhp mark

Just means another rad and water circuit though

When using a ST205 GT4 water/air charge cooler (or any higher BHP charge cooler) you need quite a big radiator to get them working properly, like smal car size... A lot of the MR2 swaps use a Rover Metro radiator! plus there's the extra plumbing/complexity to consider

... For simpicity's sake a nomal air/air intercool would be the way to go. Top mount may be an option if you don't mind having a big bonnet scoop. The later 3S-GTE's in the ST215 went back to using air/air topmounts

But there must be reason why top mount air/air intercoolers are often called "interwarmers" - especially in car like Roadster, which rather don't go at high speeds, because of aerodynamics.
So - I think water/air intercooler could be very good way - small and efficient.

Big thanks to Skov for the great price on the fuel sender. If anyone wants a standard 1.6 mk1 mx5 fuel pump give me a shout!
As you can see a nice Walbro 255lph RX7 GSS342 33911-3 fuel pump. All i need now is the plug for the sender lol

No worries :D
There's a small chance I might still have the plug, I'll have a root through all the crap I cut out of my loom and see if I can spot it.


UPDATE: I had a look through my box of MX5 wiring this evening and couldn't find it :(
Have you tried the MX5Nutz forum?

Will see if i can find one on the MX5 forum

Nosecone now split and repositioned. Looks quite mean i think need to work out what to do with the center grill bit to split the air between intercooler and radiator. Can now organize the radiator and intercooler now i know how much space i have.

Also decided to go for a 2mm steel floor welded rather than ally.

Anyone see it being a problem with having the seat runners welded to the cross bars but then the bars bolted to the chassis?

Pedal box fitted at last!!! Can do seats next and steering wheel. Custom full cage will be ariving next week. Will order radiator and intercooler next week also. Fuel tank should arive in a week or so. With any luck can get the thing running over the next month or so.

Has anyone got a spare Sierra steering column? Will be ditching the granada one.

(Rob and his new toy!)

Full cage just arrived from Scorpion Car Parts it looks great can’t wait to get it down to the garage and installed. Will upload some pics soon!

Might i also add that the customer service there is fantastic and has a brilliant price considering most of its design is custom! Full on cage with front and rear hoop rear braces, harness brace, and top braces. WOW is all i can say and the bends are fantastic no kinks at all.

Also getting a custom MX5 fuel tank from them as well yet again another smashing deal! HIGHLY recommend them!

Hi there,
Must say car looks stunning...:cool:
Do you plan to use it for track days or road use or both, which ever it's going to be a handful by the looks of it.:eek:
I see you have a balance bar on your brake pedal but I'm sure I read somewhere that you have to lock this off once set so it cannot be adjusted for the IVA, maybe wrong but I'm sure somebody knows.
Some amazing work you have done there, whats your plan for the rest of the body kit.

Keep up the good work and the photos coming.... Johno

Balance bar is ok with a lock nut and a pin, and a sticker stating not to adjust it.

I agree its going to be a hand full, my little zx9r engine can kick the back end out and its probably got about a 10th of the torque LOL. Make sure you've got plenty of travel on the loud pedal, thts how TVR used to do traction control :D

:D its going to be great! Just ordered a load more metal today to make the trunking area for the lines. Also more 20x20 box to build a strong frame for radiator and intercooler. Oh and some 50x25 box to make the seat section.

One word.....

Beast!!

:D

Good news! i have found the perfect size factory made intercooler that can take a load of power! Sierra Cosworth woooo heh

Steering column fitted WOOOOOOO.... But bit of a bugger as the extention is VERY close to the engine mount. How close do you guys think i can go? Or should i do what i have mocked up in the picture and follow the internal chassis rail then go upto the column?
