dave hard Posted November 4, 2003 Share Posted November 4, 2003 I'm aware there are a few cosworth powered 7s out there. As I am looking into swapping the K for one of these are there any specific issues to bear in mind? Obviously more power means more heat to try and lose but what else should I be worrying about? I have already decided to drop out the 6 speed and replace it with a 5 speed box. Due to a near complete lack of necessary spannering skills my role in this will be restricted to management and test drives 😬 oh and supplying the funds   Caterham 21 VHPD - one of the few Link to comment Share on other sites More sharing options...
Bananaman Posted November 4, 2003 Share Posted November 4, 2003 From what I can gather, Cossie Turbo Power can be a bit of a hadfull & needs a fair bit of space The only 7 I would think about installing this engine would be a Dax 4x4, due to larger size & 4x4 traction. Have you thought of the Duratec / VX route? Only a thought. SEiW500, see ya later......... Link to comment Share on other sites More sharing options...
dino ferrana Posted November 4, 2003 Share Posted November 4, 2003 Go Duratec Dave it will be much easier and will I think be a nicer car to drive. Also means you can keep the 6 speed. Link to comment Share on other sites More sharing options...
dave hard Posted November 4, 2003 Author Share Posted November 4, 2003 ah yes Duratec - the engine of the moment. As the bandwaggon went past I gave it a long hard look and then decided that it was going to be far too expensive to justify in terms of "bangs per buck." Easier to fit? hmmm not sure about that. Possibly easier to fit to a 21 than a 7 due to less exhaust hassles but still tricky. VX is still an option - there is a 21 floating around with one and very nice it is too. Keep wondering if I could squeeze in a V6, the Alfa Romeo 250bhp perhaps.  Caterham 21 VHPD - one of the few Link to comment Share on other sites More sharing options...
KevSull Too Posted November 4, 2003 Share Posted November 4, 2003 Dave, normalbloke29 has a quite remarkable cossie 7. Unbelievable how it all fits in, but it does. He's probably your bet bet. 😬You laugh at me because I'm different, I laugh at you because you're all the same. 😬 Link to comment Share on other sites More sharing options...
DanB Posted November 4, 2003 Share Posted November 4, 2003 'ullo DH3, Don't worry about the power - if SteveW can survive with a 260bhp Striker on Goodyear granite-compound 185 section tyres, I'm sure you'll be fine in the Nippy Truck. I imagine that, as you said, heat and more particularly cooling, would be an issue. Not only will you need a chunky rad to cool the engine, you'll also need somewhere to put a decent sized intercooler - either that or a seriously chunky rad and use a chargecooler to cool the air/fuel mixture. The exhaust will be on the other side, but I don't see that that should be a particular problem. You'll have to uprate the springs at the front to take account of the heavier engine, but that should be about it. Dan Link to comment Share on other sites More sharing options...
Joe 90 Posted November 4, 2003 Share Posted November 4, 2003 The cosworth turbo engine is too tall to fit under the bonnet and there's no room for the turbo. the 50 extra kg up front will mean that you will have to sort out the spring rates and handling afterwards. The duratec is definitely easier to install, but we'd all be interested in the result if you succeed. About to unpick the wiring loom Link to comment Share on other sites More sharing options...

Dobuy Posted November 4, 2003 Share Posted November 4, 2003 Slightly OT, but I scanned the CCC article on the Raceline and Minister Duratecs.

jackb_ms Posted November 4, 2003 Share Posted November 4, 2003 Dave  Do Something different fit the twin spark 2.5 V6 by Alfa. It would be very interesting and i'm sure you have the room, if Clive and Andrew wanted to fit a V8 in MLE 😬 Have fun Jack    Emily, The Very Yellow 21 Link to comment Share on other sites More sharing options...
paul w Posted November 5, 2003 Share Posted November 5, 2003  A little off topic but here is a turbo-ford powered '7' with 570bhp/tonne. It is a lesser '7' but looks like great fun nonetheless! Had one of these Chevrons years before the S4 and whilst being a little agricultural they are great cars, I've seen them rolled and cartwheeled and running again a week or two later. http://www.f40.co.nz/f40/Chevron.htm Link to comment Share on other sites More sharing options...
