I got the steel through work as only cost me just over 50quid

So well happy with that, just that I've been working away for a few weeks and then at weekends had no energy to do anything. But now I have started I should have a bit of motivation to get on with it now it's taking shape (sorry for the rubbish phone pics)..

But here's the beasty that's gonna power it..

Cost me £75 with the gearbox but no dizzy, guy that sold it to me said it was an old 12A as it had the Nikki carb and manifold. I got home and found out it was a 13B but someone had got an adapter plate to use that carb and manifold so I was happy with that. I later found a 12A and got it for £25 with a dizzy so got it just for that.
I've since made a little test bed for it so I can run and set it up, not gonna keep this carb, a 48DCOE is going on it later or maybe a set of 34/36mm bike carbs depending on how easy it is to set them up.
As it's an old '85(ish) FB motor they were supposed to push out about 120 horses but with a free flowing exhaust and a weber you get about 180. But this bad boy has had a bit of flow work done so hoping for either a street port (200hp) or even better a bridge port (250hp) should make for an interesting little screamer :D

Have you had a chance to rest this little lot in the chassis yet to see how it all looks?

No not yet, will see if I can get an engine hoist though as I'm going to need one sooner or later so may as well do it sooner :D

These rotary lumps are something else. the guy I got my rx7 hubs from reckoned there are some 600hp rx7`s out there. I took that as pub or magazine hp but they really do exist. This one is N/A http://www.streetfire.net/video/allm...en-rx7_549.htm. :eek:

Bob

Yeah but thats a quad rotor Bob, PPort 13b's can hit 300bhp. 20b triple rotors can hit 450bhp.
Then you start on the turbos... stock twin turbo 13b's hit 300bhp, max stock twin turbos hit 400bhp, massive single turbos hit 4-600bhp. Turbo 20b's hit 8-1000bhp, 26b's (quad turbos) hit 1k-1600bhp.!

But then you get one of these that comes along....

12 rotor anyone.? 2600bhp+ turbocharged :eek:

And here's a straight 6 one off..

God I love these engines..!! :D

I can see the attraction:eek: :eek: :)

I've always said these engines in a roadster would be phenomenal, much better than a bike engine. They just need someone to go out there and build one to show what they can do.

If i had the money mine would be coming together in the garage now - should have stuck to my original one with Saturn but changed strategy half way through, deeply regret that now.

All the Best with the build and ENJOY.........AndyH

Thanks Andy. :)

Page 3, hell it's been a while but been working weekends most of the time but really nice to get time off.

So update time, I'm still tacking up but got a bit of the back end done and the transmission tunnel done. I need to get some 3mm plate so I can start making brackets and plates.
Need to re-do TT8 and 6 as I cut it to the MX5 amendment but it's not done as the up and over done in front of it but I'll cut it out and make it with 45 angles on it so I don't have to cap it off now I know how it all lies and is also square.
Going to go around and make sure every single box section end has 4 tacks on it before I start to weld it all up so it doesn't pull.
The sharp eyed amongst you may have noticed that U7 has moved :D

Come on put us out of our misery.:) Shove that lump in the frame at once and take some piccies:) :) :) .Dont think I can wait any longer.

bob

loving the framework :) any chance of a close up, middle of the wall about half way up :D :D :D

Been a while, but I'm starting to get time and also get back into playing again.
I managed to clear some space and get the frame on some tressels but the one at the front is too wide so when I tried to get my engine in it was a no go so I lowered it onto an old toolbox and some axle stands but I got the engine in.!
Though I still have a bit to do as I have to cut and re-enforce the top rail as the clutch slave is gonna go clang and also it will go a further couple of inches back.

One good thing to see is the the only thing above the chassis rails will be the alternator (may move this to the side), oil filter and my carb (not sure what route I'm going to take with this yet).

I treated myself to a cheap usb endoscope for my lappy, all though the resolution is not fantastic I managed to jam it into my ports and see that I do have a large street port. I shoved it into the exhaust too and it just saw a large grey area as it is immaculate inside, no scores marks, just some lapping marks from when it was rebuilt and by the looks of it it's done nowt since it was done, I'm a very happy bunny :D
