1972 Manta SR

Recommended Posts

Hi, im new to the forum as this project is my first manta. I have aquired it off good old ebay after it had been shoved through the garage wall. I decided i would be better with a few bent panels than a lifetime of rot and am glad i made that choice because she's a beauty and becoming straight no sweat

its an auto so thats got to go and even though the engine is a minter i think il change it allong with the gearbox. My thoughts ar 16 valver and getrag box, but the red top with the coscast head seems so hard to find, does it really matter and are the later ones ok too?

I intend to leave the bodywork original (un bent of course) appart from i think i must have one of those turbo front spoilers!

As soon as i find a way of posting some progress pics or a link i will

dont worry about the coscast, its nice to have but not vital. just make sure its a 16v xe and not an ecotec. If its the green A Series I suspect that you've done well there. Yes a lot of straightening but like you say probably easier than a lot of rot. Good luck, make sure you join the club as you'll find theres a lot of good people with a lot of great advice!

Ah, ive done it! check out this link to see some pics of my car as I got her and after a little reverse bashing.

Ive decided that i need the upper front pannel in front of the bonnet. looked on dr manta and this item is about £200. This would not be so bad if it included the bit under the front edge up to the light fixings, but i cant tell if its just the skin or not.

Doesent look like you can get the bit between the light fixings and the vallance so i guess il have to reconstruct that.

Front vallance will survive, especially if i can cover it with a spoiler!

You cant get the part of the front valance that the lights bolt into, for that you would have to buy a complete front and thats silly money, the top part you mention is the complete bit doen as far as the top of the lights.

Spoiler isnt a problem as there is a guy in the Uk who makes them I got one lately thanks to Russ, so if you need the info I can pop it up for you.

As for the 16V conversion that getting expensive some people are paying over £200 for the sump alone which in mental. The other thing I have noticed is that nearly all A series cars lately that people buy get modified engine wise, I'm a culprid there as well [:D] I have started another one and I,m doing my best to keep it on a standard track [:)] To pick up a manual gearbox, pedal box and clutch cable should not be to hard. It might be worth sitting back on the engine mods and seeing where u really wantto go with the car.

Cheers Robbie, that helps a lot. it doesent seem such silly money if it includes the piece underneath rather than just the skin. As far as the other bit goes a little fabrication should fettle that no bother.

think the spoiler is a must though!

The standard CIH engines are nice torquey units and really pleasant to drive with the 4 speed gearbox. I'd stick with that for a start and see if you like it or not.

I've a spare 4 speed 'box if you need one.

You could also consider fitting a Frontera 2.4 CIH engine which would keep it looking original but with loads more umph. Ask 'Paulmanta' (one of my fellow Moderators) on here about that.

Handy workshop by the way!

Cheers,

Joe.

Thanks for the offer of the box Joe, I can see I have some serious thinking to do!

Only thing is the original engine is running on lead replacement and getting the cylinder head converted to unleaded is an extra cost, which I thought I might be as well investing in an engine with a little better economy. I heard mid 30's mpg is achievable with an injection red top while still having plenty of poke when wanted. With a five speed I was hoping I could cruise along quite nicely at lowish revs when on motorway journeys.

Does the four speed not run out of steam quite quickly, and would I be reving rather hard on the motorway guzzling fuel. This 2.4 Frontera sounds like a bit of a guzzler, is that the case? Plus the red top sounds like too good an engine not to have one. My experience is with diesel engines but didn't really want to resort to putting on of those in!

I've never given the fuel economy of the 2.4 any thought to be honest. I wonder if it would be better than the 2.0 as it's a big engine in a small car, or whether it would simply use more due to the increase in capacity. The 2.4's will all be unleaded but you'd need a late 2.0 for that to be safe.

We must be very environmentally unfriendly one here. I can hardly ever remember anyone asking about MPG!

I think the 5th gear in the 5 speed box is a higher ratio than 4th in the 4 speed so yes, you might be revving well on the motorway.

If you want a cheaper alternative to the redtop, the 2.0 SOHC 8V (Cavalier SRi etc) engine is another option, and they'll certainly be okay on unleaded.

I must admit I do still fancy an 'A'.

Cheers,

Joe.

Joe...Buy an A !!

John, the 2.4 doesnt drink much more than a standard GTE, and can make around 170 bhp if you do a little work, not expensive work either, just time ! i have done the conversion for a friend and we were amazed by the transformation from mild 1900 to fire breathing 2.4.

I used a 2 litre 5 speed box, modified the tunnel a little, and used a 2.2 carlton injection system with 2.4 injectors. very torquey and extreme fun, am going to find out if the car will be at Billing this year.

Climbed a mountain and turned around

Keep all these snippets about the 2.4 coming Paul and I'll end up being able to write that article for Manta Magic you promised me (ahem...) for you!

Cheers,

Joe.

when I decided to get a 2ltr, 20 yr old coupe with more miles than the space shuttle moaning about crappy MPG seemed a bit ridiculous.....

Maybe so, but whats the point in having a cool car if you cant afford to drive it. Thats ridiculous, ends up being parked up and no one gets to see it, now that would be a shame!

Why should it cost you more to get less power, seems simple to me, especially when their are more modern alternatives around that dont require detremental alteration of the car.

If I ever get my hands on a jag v6 diesel, that will be straight in!A little too rare at the moment unfortunately.

Hi John

Nice to see that car getting saved. It did look mint underneath[:)].

I have 1.9s and 4 speed, I think it was close to 4.500 revs at 70mph and I think it was 109mph flat out.

Did the 2.0 16v conversion and it's very expensive! And I've still used mostly second hand parts. But I'm looking at 200bhp now[:D]. You've got engine, a bloody £200+ big wing sump, engine management, exhaust, manifold, radiator and fan, hoses, fuel system, intake (I used throttle bodys so I could do away with dizzy and clear the brake sevo)and loads of other stuff to get right and hunt for parts. There are so many things to do and I'm still at it!

Take a look at what I've done and had done to my 'A' John: manta73.zoomshare.com, I'm doing the mods first getting it all right, then next winter strip down and restore the underside and new paint. And maybe a fat chrome rollcage[8D].

Don't worry about mpg, NO TAX[:D] and VERY CHEAP INSURANCE[:D]

See yu

Never, ever, bloody anything, ever!!!!!

Ive posted a couple more photos on http://72mantasr.blogspot.com/ As can be seen from the photos the boot area is more or less straight now. I managed to pull the lower vallance fairly well by wellding a nut on to the panel, then using a threaded rod to pull the panel out. I just cut the nut off and moved it allong. This saved me from drilling the panel with a load of holes.

I got the front panel removed also. This took ages drilling and grinding all the spot welds. Im glad the wings are bolt on! I think I might rivet the replacement panel back on as this will allow me to get a nice amount of paint and waxoil in the seams. It should save some hassle too as I dont have a propper spot welder.

Haven't made my mind up on the engine front yet. I do have a couple of ideas up my sleave but of course more power does of course lead to the requirement of better brakes. Rally Design (http://www.rallydesign.co.uk/catalog/default.php) have a nice wilwood four pot front brake kit for the chevette and manta but all these costs add up. Thought I could save some money by moving the front brakes to the back and run a hydraulic hand brake, but it seems the mot requires a cable one. May see how an Audi caliper looks on the back.
