SE 6b cosworth 24v

Post by shortjedi » Fri Feb 26, 2010 5:38 pm

Here we go then, my experiences of converting a 6b to cossy power....I'll start by giving a quick overview of my scimitar history....First one a 1972 5a. then a 6b that I converted to 2.9 inj. and did a few hillclimbs in. then an ss1 turbo that I did a lot more hillclimbing in (best car I've owned). In between I'd run a westfield
(to scary) a couple of Elises(brilliant) and a Grifith 500 (beast) That brings us back to the latest 6b an ebay £500 runner with galv chassis.
Having already done a sucessful 2.9 swap several years ago, thought I'd have a go at the cossy...As Clarkson would say "how hard can it be?
Well..... I'll start with a bit of a shopping list and the rough costs:-
1. Engine. £300 ebay. nice man who'd stripped it from the granny complete with entire loom and (autobox sold on for £100), to put into his ford pop then decided to go chevy LS1. (nutter)
2. Gearbox.£300 you need an Mt75 hybrid. XR4x4 front, diesel transit rear with tall top gear. got mine from topboss in derby along with (xr4i) flywheel and clutch slave mount. it's a common mod.see caprisport website.or they do come up on ebay.
3. Propshaft. £120 custom made by local propshop
4.Radiator.£20 topboss had an odd one that fitted after slight mod and pressure check.
5.PAS pump.£100 this is a saxo electric/hyd pas pump new off ebay. Astra or polo will also work.(not much room for belt drive pump)
6.Exhaust. £800 custom built inc manifolds. Flanges supplied by topboss £60....this was a big expense, but was a lot of work and beyond my welding skills.
Sold most of the removed big bits on ebay. recouped about £450 so far. I'll go into more detail over the next few weeks.

those are some good numbers - are you Scottish? :D

500 for a running galv 6b :shock:

20 for a custom rad :shock:

with another 25-50% on bits and bobs (?) plus a respray - not counting your manhours, it'll still be a bargain when it's done :D

Nice work mate. I am wanting to do a conversion after taking my engine for a rebuild and got my quote back and realised that it would be better do to a conversion as it would prob be cheaper, faster!! and more effcient.

Im looking on ebay and they've got plenty of parts available and was just wondering could you do the gearbox conversion yourself and is it easy. Do you need 2 gear boxes. 1 xr4x4 and a diesel box and mate the front and back together. Or easier see if 'topboss' have got one for sale.

cheers

Sam

That looks fantastic! Top work! I would love to do the same to mine eventually. Do you think a Capri 2.8injection gearbox, prop (suitably modified) and axle be used instead? I have to say that K&N filter looks suspiciously small for such a big engine though! :o

Hi craig, yes we've met a few times, mainly at loton. I used to run the yellow ss1 turbo. Sold you a blank hardtop..Can't see me racing this car but I plan to do some sort of competition with the Ginetta G15 when I get round to rebuilding it. The bits are slowly coming together. Just not sure which direction to go engine wise, blown, injected or webers. Maybe even a bike motor.. See what turns up.
.......Back to cosy motors. According to the capri boys, 2.8i gearboxes (type 9) are not up to the job. Don't know why you would want to swap the axle over, more work than a custom prop and weaker.
.......Hybrid MT75 is a common mod. I don't see why you couldn't diy it, the info is out there. best info is on caprisport.com he also supplies some of the bits.
.......As for doing this conversion rather than rebuiling the original engine, I'd do your homework first. Bear in mind that I've used a lot of used parts and fully expect to have some associated problems. If you have a duff engine and limited funds why not fit a used motor whilst rebuilding the original yourself? Or, if you're looking for more power with less work maybe a 2.9, 3.5 or 4.0 cologne is worth a look.

Getting close to road worthy but still waiting for new shocks/springs from protec. I'm trying to identify the paint code from the chassis plate. which bit is the code out of this lot? SCD 190155EK005821. It's a solid red, think it's original.

The colour will be "55", but i've no idea what that is (don't have my reference tables to hand ATM).

I think 55 is the same as mine: Carmen.

Although yours looks a lot redder.

Not lived outside so much, I guess?

SCD = Reliant
19=GTE
01=Overdrive
55=Carmen
E=1984
K=October
005821=chassis number - yours is 15 before the one that became the Middlebridge prototype (5836 - Dans not Michaels) and 44 before the last (which went to Princess Anne)

Thanks for the info guys, great stuff. Done a bit of fetteling this week. Removed the gear linkage to fit a quick shifter as the throw was to long and hitting the arm rest/handbrake in reverse. So here are a few photos of the linkage. ImageImage
This is a shot taken of it fitted from under side, the propshaft is removed for access and the finished article. I made up a finishing plate and covered it with some black leather cloth. just needs a clean and some polish on the leather bits.Image Image
This is a poor shot of the pas pump in situ. it's mounted under the rack just behind the radiatorImage

Hi, don't suppose you have any measurements for the BOA and/or the Essex? Highest and widest would be good too Cheers Tee

I'll have a measure of the boa I've fitted when I get it back from Phil Brad exhausts, he's fitting center boxes as it's a bit to loud.
I've not posted an update for a while so here it is:-
The car has been on the road for about a month now, and is going very well. I fitted the new shocks and springs (protec)and Danny fitted the new anti roll bar. Which means it goes round corners very well. Huge amounts of grip. I now need some more supportive seats as I'm getting thown out of the originals. any ideas? not fixed buckets as I still need access to rear. Looks like the paint job and recarpet will have to wait a while as my daughters wedding is eating all my spare cash. thanks for the replys about the colour codes.
