Beachcomber's 940 Estate project

[beachcomber]

Just tried to post up - but it vanished into the ether.

Rather than waste another 30 minutes of my life - I'll try this small post to see if it works this time.

Car is a 1991 940 SE Turbo / Auto in superbly maintained condition.

Currently off for MOT [ tailpipe / back box ] before the fun begins in a week or so.

As bought

thanks for the pictures - What turbo is that?

E-Bay special !!!! £125.00 "buy it now". Well made - I'm guessing Chinese.

So here’s my 940 SE Turbo / auto Estate project.

It’s based on a 1991 model that has had absolute fortunes spent by the PO – including new Turbo, cylinder head, radiator, power Steering rack and pump, brakes, hoses – you get the picture. All within the last 18K miles.

Due to an ongoing health issue this will undoubtedly be my last project / plaything – I’ve had to sell off all my motorcycle [ x 3 ] and Hot Rod projects since receiving the diagnosis.

After a life of designing, manufacturing and marketing my own range of Porsche, Jag and Cobra replicas [ and still do design consultancy ] – tinkering is firmly in my blood, and to have NO project to work with [ no matter how small ] is to lose interest in life.

So, the 940 will be it. Initially mods will be cosmetically based – lowering, Jag 5 spoke wheels [ 7.5” x 16” ], relevant spacers, roof spoiler, etc.

I’ve ordered 40mm and 50mm thick alloy billet blanks for the spacers and the 25mm longer wheel studs arrived today.

The car’s due back from MOT work next week [ tailpipe and back box ] so I’ll make a proper start then.

Originally [ pre- diagnosis ] plans were for a Supercharged V6 [ Volvo ] or supercharged Lexus V8. Due to the long term nature of such a conversion – those plans had to be shelved, and after a good talking to by the Turbo freaks on another Volvo forum, I’ve decided to go down that route. Good V6 + trans’ [ manual and auto ] anyone ?

Speed / ultimate performance isn’t the goal here – been there, done that and got several Tee shirts, just a mild engineering challenge.

I’ve been given a new T3 Turbo by a pal, who no longer needs it and a suitable T3 manifold from another. A 2.3 Turbo lump came up at silly cheap money – so that was snagged for the build. Just need to get my head around the alien subject of turbos and associated squitter and collect the rest of the parts I need.

Funds are tight – OAP pension doesn’t stretch far ! That’s supplemented by various E-Bay sales of 50 odd years of collecting and now, redundant parts.

Progress will be relatively slow, but the plan is to use this as a daily driver / project and to sell my V70 as soon as practical.

Although the paint and body are again in remarkably good condition [ NO rust ] – I can’t stand yet ANOTHER Silver car – so a colour change will be considered down the line.

BTW – I need an o/s rear light lens that doesn’t involve remortgaging the house and I could do with a set of bolt on [ ? ] roof rails.

No Dave - been a lifelong auto freak ! Even my Drag Race cars were auto. I have a tame auto man I've used for 40 years who will do the neccessaries to my spare ZF box down the line. Like I said - ultimate performance is NOt the issue here.

Some nice toys there :D :D

Moved to projects for you.

LOL, ta. Haven't you buggered off to oz yet :P

In the USA they all use autos on the 940 and do a accumulate mod to help pick up and kick down .go on tbricks and put in accumulater mod and that gives you all details on how to do it .i would use the 940 manifold because it flows a lot better than the old t3 manifolds .all you have to do is mill the mating surface flat

Thanx for the headsup - I'm new to Volvo 4 bangers and Turbos !

The guy who is helping me out with these specific mods knows his way around these items.

I'll check out the Auto box mods, but my auto doctor will no doubt have just the fixes I need.

Thanx again.

I haven't got much knowledge regarding volvos it's just what I have read that's all .you are also local to me too .im in Birmingham

[beachcomber]

Smithy,

I've noticed there's quite a "nest" of modified bricks / projects in the Midlands and around the Birmingham area.

Have to arrange an informal meet when everyone's on the road !

Yes the does seem to be a few around with reading here and voc

[beachcomber]

Would that be "Brummie Bricks" then !!!!!!!!!!!:slap:

DD - thanx for moving the thread - I guessed I was in the wrong spot !

Yes, I've been blessed with building / owning many off the wall cars - Race and Road.

My "day job" for the past 40 years [ retired in 2003 ] has been involved with designing / manufacturing Cobras, Jags, Porsches [ replicas ] and having a hand in many others.

Naturally, I was forced to drive these around !!!!

I still carry out consultancy work for my pal at Realm Engineering Ltd.[ C Type and D Type Jags ] and a German pal who builds Cobras and Gullwing Mercs and Roadsters.

[beachcomber]

To my surprise [ being Easter Saturday and all ] my new back box and tailpipe arrived today, so I'll be able to drop them off to the workshop on Tuesday so my pal can get on with the MOT.

£38 delivered - not too bad eh ?

BTW - anyone know of relevant referrence / history books covering the 940 ?

[beachcomber]

Exhaust now dropped off to workshop and I also collected the billet alloy blanks for the wheel spacers. In the end I played safe [ ? ] and ordered an extra set in 50mm as I haven't got the car to hand to make final checks on clearance. Looks like the fronts will require 48mm for my Jag wheels.

I've actually got 43mm and 53mm thick so that a "Hubcentric" flange can be added.

However as stated previously - that does open the door for a whole variety of possible OEM 5 on 108mm wheels down the line - still fancy the Alfa Teledials !.

[beachcomber]

Oh futtox ................. what's that about trusting information that hasn't been verified personally ?

I dug out one of my spare Jag 5 spokes today to offer up the billet blanks and double check preliminary measurements. I was given information that the Jag wheels had a 6" backspacing = 48mm spacer [ front ]. I based the data for the blanks based on that as I didn't have the wheels to hand at the time. After I dropped the blank in place - it was obvious that the backspace was NOT 6" - nearer 7" [ 6 3/4" ] ..................... oh dear me.

[beachcomber]

I've just spent the last hour or so going through the various what will / will not fit threads.

I've now come away with a serious headache due to information overload and contradictions.

Here's where I am and the info I want.

I have 7.5" x 16" Jag 5 spoke wheels [ 5 on 108mm ] with brand new premium tyres. They are surplus from another project and owe me nothing - ergo I want to use them.

Let's forget inset, offset, underset and any other bloody set - my wheels have 172mm back spacing - the ONLY masurement I'm really interested in - as that will determine [ with relevant spacers ] what will fit and still clear the strut etc.

As peeps have fitted 8" and even 9" wheels - my 7.5" wheels MUST fit under the wheel arch lip.

What I ideally need is the measurement from the hub face to the nearest point of obstruction [ strut ? ].:nod:

Why don't I just measure it myself ? Simples - the car is away for a couple of weeks awaiting MOT and I have no access to it. However, I would very much like to get the spacers underway. I have purchased billet blanks and aftermarket wheel studs [ +25mm ] and I've found a guy that will machine them for less than the National debt required here in the UK to buy off the shelf spacers [ if they even exist in the size I need ].

So ............... if ayone has the time I would very much appreciate that dimension - hub mounting face to nearest obstruction.

Incidentally there's a whole bunch of good looking OEM 5 on 108mm wheels out there from European manufacturers. - and cheap !

[beachcomber]

Some progress anyway.

I collected the 2.3 Turbo engine Thursday. looks really clean and apparantly was "running well [ no noises ] but losing a bit of water". Well, it's being stripped as a donor lump to set up the new Turbo and other mods so we'll see what damage has been done - if any. The plan is to build up a complete unit with my ZF gearbox all ready to drop in - then a quick swap over, it says here in the script !

I have some info courtesy of another forum re: the backspace of various Volvo rims, and I'm now certain my 7.5" x 16" Jag wheels can be persuaded to fit.

[beachcomber]

Well that's the longest "two weeks" ever ! Due to my pal's overload of real paying work [ !! ] and a mutaual arrangement, we decided to leave the MOT until the end of the month [ April ] so I could tax / insure it from the 1st May.

The car sailed through the MOT - the back box we knew about + 2 wipers - not bad for a 26 year old car. The MOT guy said it was one of the best cars of that age he'd ever seen [ underneath / mechs etc ].

In the interim I unloaded the 2.3 lump out of the back of the V70 [ eventually ] and bought a set of -40mm Kilen springs and Bilsteins [ new and unused ] from a member of another Volvo forum. I'm pretty certain I need 50mm and 70mm spacers to fit my Jag wheels, but I'll take an accurate measurement once the car is back - don't want to get them wrong !

Looking forward to some real hands on work - even if it is only cosmetic to begin with.

70 mm spacer sounds a lot..good site below for comparing effect of different offsets

http://www.willtheyfit.com/

Internet says 940 wheels were 25 offset & those jag wheels 61 offset. so a 40 mm space would bring the face of the jag wheel out 4 mm further than stock ones. I looked for some info on spacers increasing scrub radius vs handling also, not for scare mongering just for some thoughts on it.

I've been down this road before - there are obviously at least two different offsets / backspacings for various Jag wheels of that era.

Without question - mine measure 72mm back space. I based my original billet blank order on the info listed on some sites.

The reason for ordering the larger thickness blanks is so they can be machined down as required with a "Hubcentric" flange. At this stage, I'd rather have them too thick and machine to size !

However, my car is hopefully coming back from the workshop today, so all the guesswork can be remedied this coming weekend.

BTW - "scrub" is measured using the CENTRE of the tyre as one referrence point. That is only altered by the width of the tyre within the wheel well. The other referrence is the "Steering Axis Inclination" - which is fixed. Don't blame me for the inacurate [ NTS ] drawing I whizzed off the internet - the "centreline" on the right hand drawing - obviously isn't ! But that's the general idea.

Thanx for everyone's input.

Fair enough about the machining down, I was thinking you were adding a 70 mm spacer somewhere....hence was thinking scrub radius would be increased if on the front - https://en.wikipedia.org/wiki/Scrub_radius
Scrub radius is changed whenever there is a change in wheel offset. For example, when the wheels are pushed out from the body of the car the scrub radius becomes more positive

(or a more long winded reference Competition Car Suspension by Alan Staniworth.....3rd edition available on the net - search for "Competition_Car_Suspension.pdf")

ps can you see CH 60 stamped on the back of your wheels somewhere - that should mean offset is 60

Thanx for your continued input.

To be clear - I'm talking about the "BACKSPACE", not the offset. The backspace is the only measurement that is of any interest to me as that determines the spacial position of the wheel and the clearance to any restrictions - struts, wheel arch lip etc.

I know the Staniforth book [ and Alan ] very well, I have a 1st edition personally signed copy in my library.

All will become clear [ or not ] in the coming weeks when I can physically check the car against my wheels!

Yes understood about the backspace it is easier to measure than the offset. If any use I have a spreadsheet of the calcs in Chapter 8 of the book mentioned, I was using it to work out different corner loads depending on anti-roll bar thickness

[beachcomber]

Just collected the car from 5 week's hibernation having MOT and various bits done. What a pleasure to drive. I had a direct back to back comparison as I drove up to my pal's workshop [ 10 miles ] in my V70 [ which I left there for a service ] and 30 odd miles back - just for the hell of it ! The 5 week delay was no fault of my pal BTW.

Thanx for the offer of the spreadsheet - but as stated - I have an original signed copy of Alan's book in my personal library. I also did a lot of the original "string computer" work when Alan was devloping his "Terrapin" race cars.

I've decided to go ahead and get the -40mm Killen springs and Bilsteins fitted [ all round initially ], then I'll start in earnest on the wheel swap. I know peeps have fitted up to 9" wide wheels on the front - so I know my 7.5"s will fit.

OK fella no probs I meant a Microsoft Excel file with all of the load transfer formulae so you can input your own numbers to complement the book. Sounds like you have no need

[beachcomber]

Hey .................always learning !

The first 50 years just gives you the groundwork !

[beachcomber]

After several delays the car is now fitted with the -40mm Kilen springs and Bilstein dampers and I'm collecting it from the workshop tomorrow with a 13 month MOT.

Then I'm off for a short chill break to Saxony and on my return it's full steam ahead.

First job is to FINALLY measure the available space from the hub face and the Jag wheels so the spacers can be accurately determined and I can get them made. Rears are not a problem - just a case of placing the wheel spacially to fill the wheel arch up, so the billets I already have will do for that [ I have 40mm and 50mm]. That just leaves the front to be determined.

Insured today [£135 Fully comp ] so I will be putting my V70 Auto on the market soon and using the 940 full time.

BTW - the "-40mm" springs actually yield 1 3/4" at the front and only 3/4" at the back. Looks OK, but another 1" or so would be better !
