940 front end on my 740

[kevro]

I would really like to upodate my car 1990 740t with an s90 front end or something similiar. i am able to find random pics, but no info so far. anyone know the whole process or some of it?
Thanks

costs alot

I attempted the conversion.

just parts alone made me decide to drop it.

but its not that hard, just lot of money cause they didn't sell that many S90 in North America, and few of them end up in junkyard.

Here's a little info from a guy who's done nearly everything to change the look of a 745.

Juha P... has done this to his car. www.volvonet.org/tpc/

There isn't any info on his site, but you can email him. He used to have all the steps in picture form on the internet.

^^ Juha did a 940 front end conversion.

its pratically a bolt on , it doesn't require much modification other than the bumper support.

S90 front end require to chop inner fender support, bumper support, healights bracket, and if u want to use S90 hood, u need to modifie the firewall.

I want to do this too, convert 940 to V90

Some discussion in Off Topic - Volvo owners in UK

[ThinkDifferent]

Chigga, how much would it have been??

Cheers

For the last few years I was looking into it. Parts aren't that much, you just need to look. for 90+ the stock hood works with the fenders, the bumper is the only hard part to put on. If you want the S90 i think some plates needed to be welded for the hood i believe i spoke with Peter M on it, I have sourced a front clip but I am not planning it on the car I have now.

It takes time to install it and thats about it, unless you have a pre 90 car.

Late.

Ok so I am looking around to determine whether the windshields are different from the 940 to 960, and whether the post 95 960 hood is the same as the pre 95 960/760 hood. Welp they appear to be identical;

The hoods look the same, if you look closely you can use any hood from a 760/960 88-98. Odd that volvo never seemed to change the hoods for safety reasons. That is also odd is that you can use a 940 hood in conjusntion with the front of a V90. Instead of the hood comming up the the windshield it meets a cowl and the winshield wipers are mounted on the cowl instead of below the hood. I am doing this hood mod for sure. I don't plan on goind as far a V90 front end, but I like the way the hood that goes up the the windshield looks better, and the way the windshield wipers tuck under, looks really sharp. If you look at this car you can see that the fender design as others said doesn't have to be changed if you own a 940 or 90+ 740 seems to work too. This car oviously uses the same fenders but uses a 740/940 hood:
http://www.volvonet.org/tpc/vall/images/vall02_069.jpg
I don't think you need to touch the firewall or change the windshield since there are some cars with stock 940 winshields and stock 940 wipers just tucked under the longer style hood.
I hope Juha doesn't mind me posting his pictures, I would use pictures of my car if I had a digital camera. I will make sure to take pictures of my car in future examples. I don't like posting Juha's pictures, so if he wants me to remove them I would absolutely do that.

[JuhaP]

The difference between 940 and 760 '88+/960/90 hoods is actually quite big. Fenders are different, a-pillars are different, ofcourse the hood is longer, there are no hood springs but hydraulic shocks, the wiper system is completely different and so on. A lot of work.

But as you can see on the last picture (black 700 or 900 converted to s90 -look), this guy has used fenders, bumper, lights and grille from 960/90-series and the hood is from 940. So you can mix the parts.

PS: You can post the pics, no problem, as long as the website address is on them :-).

[945ti]

Cool response. Now looking very carefully I can see that the 960 fenders are a little different than the 940 ones. This is odd since they look almost exactly the same. The white car in the first pic looks just like a 91-94 960 in the US. I plan to almost exactly replicate the look of the white car, but I will keep my all black 'wagon' bumpers. IT looks like the finders have a slight tiny overhang where they meet the hood, in a way that the 940 fenders lack. A-pillars are different? where? Would I have to move the windshied seal down or something? The windscreens seem to be very similar between 940 and 960, just the way the cowl meets it seems a little different on a 940. Is there any way I could do this swap without changing fenders, or would it look silly? I know I have to change the cowl and wipers, but I actually want to, so that is not an issue. Ok so looking very carefully at my also white 940 it appears that the fenders simply meet the A-pillar. On this 940 it looks as though the fender overlaps the windshield a little more. If you are willing to wait a few days I will take some pictures. IT would be nice if you could discribe what I can get away with not changing. Ie. windshield, A-pillar are the big issues. It seems that it just wouldn't work with 940 fenders. Hydraulic shocks must be the rage on euro cars, I prefer the spring. It looks as though you can still open the hood 90 degrees though which is a really cool feature of the 7/9 series volvos.

[Chigga 744SE]

I say ur best bet is to source the fender, bumper, lights and wiring for it.

the hood is just way too complicated, except if you doing a ground up restoration.

I'm sticking w/my SE look. althought I do wonder wats the drag co-efficient on the S90 compares to 700/900

[945ti]

[quote:1025aa3872] I do wonder wats the drag co-efficient on the S90 compares to 700/900[/quote:1025aa3872]
.30 or .31 on those cars depending on roof rack or sedan or wagon. Very slick indeed. I would bet with no rear spoiler no roof rack seam weld things and cover up some of the plugs on a V90 and you could acheive .29 or .28 or something. Also tucking the wipers as much below the hood and removing headlight washers and that junk will make it roll through the air better. The 945 has a c/d of .32 from the factory so there isn't a ton of improvement to be had, since most V90 are about .31. The post 90 740 is very similar to the 940, but there is a subtle difference in the slope of the headlights and turn signals and such. This is only slight though so the aerodynamic penalty if there is any must likely be small. The pre 90 740 has a c/d of .39 or something I think. Sedans tend to fare worse like the 944 at .33, but they make up for it in weight savings. Tucking up the exhaust and lowering the car tend to make a pretty big difference, it also lets you get the diff out of the airstream. I think you can mix the parts is various ways, so even though the fenders are different between my car and a 94 960 according to Juha and others you can still mix the parts. THis is evidenced by the S90 bumper fenders blah blah blah with a 740 hood on the bottom of my other post as Juha points out. I actually don't really like the S90 look as much as the euro white 900 look in the first picture. I just want to tuck in those wipers and eliminate the air grille in teh cowl. Makes for a neater look. It seems to me that there is virtually no aerodynamic gain between the pre 95 to post 95 960. Ofcourse the rounded fenders will let the air hug them a little better, but the front spoiler is more show then go. Not to say the S90 front spoiler is bad, but if the 940 is .32 and most S90/V90 are .31 or so then that more rounded spoiler must be pretty moot IMHO. What I am now curious about is this rumor that some 960's got an aluminum hood, but it occurs to me that it may not crumple properly if hit when used in conjunction with 940 fenders. This may also be pretty moot though. A lighter hood would always be nice, just need to know which if any cars they came on. It is alot of work, but iff all I had to do is fake the look by mixin the 940 fenders a-pillars blah blah, with a lighter better looking mroe aerrodynamic hood then I am all game. You may wonder why someone interested in aeroddynamics would buy a volvo, but the fact that the c/d is so low on a 940 atleast for a car that looks like a box and can hold so much stuff it is cool to me. Anyway I would like to hear more for sure.
[edit] about the S90 front spoiler, it may be that though the C/d is about the same/ slightly better, that for the same C/d the S90 generates more downforce then teh 940 or pre 95 960. A spoiler expert or someone whois more nuts about aerodynamics than me will have to answer that.[edit/]
[edit edit] Now that I look at it the S90 front end has slightly more frontal area then the 940/960 and a slightly more pronounced lip on the front which would lead me to think that the down force on an S90 would be greater relative to the drag. [edit edit/]
Sorry for sort of turning this into a performance thread, but who say looks and performance can't mesh a little eh?

[ThinkDifferent]

Yeah, in fact when the 850's came out and Volvo beefed up their Touring Car presence, they gave them estate (wagon y'all) versions of the 850R's as these not only had a lower drag coefficient but also made a really nasty hole in the air behind. Interestingly, the rear lip spoiler is supposed to make a big difference and I think they look good. Got any figures that say wether it increases or decreases drag and by how much anyone???

How do upost a pciture casue ill post picturs of my 1990 760 volvo last year of the them.. as u all know

The front end conversion is pretty straight-forward....nothing rocket science. The real fun begins when you try to swap a later 760/960 dash into an older 740......I've been mapping wires for about 2 months now. I hope to have the awesome dash (with tilt-wheel) by spring.

:roll:

[ThinkDifferent]

Swede242, please educate us more! If you've had the bumpers off your car we'd like to know all about it! With photos if possible...

Do you mean late 960/V90 or the earlier version that's like a 940?

Thanks

Which is the best to change a 850 spoiler onto a 760 or a 960 spoiler onto a 760?

[affa]

All 760, 960 and s/v90 hood are made of aluminium <- correct spelling :-P (while we are on this topic, all wagon tailgates and sunroofs are also made of aluminium)

It contains 3% magnesium to improve its rigidity.

The above information came from my volvo factory service manual.

I don't think there will be much difference in a crash situation as far as crumpling is concerned because there are next to no structural difference between a pre-95 960/760 and 940/740 in the same era.

Post-95 960/s/v90 has longer frame rail up front and does not use the gas impact absorbers behind the bumpers (it uses foam instead). So there will be some work involved when you're trying to mount the newer 95+ bumper onto an earlier car. But thats no biggie.

Windscreens are different, but not really enough to cause trouble me thinks. 760/780/960/s/v/90 uses PUR as the aheasive (740/ -94 940 uses butyl instead). They also used different mouldings around the glass. I also believe the glass is a little longer (taller). From 94 onwards volvo updated the 940 glass to a longer version and only the new versions are kept in stock. I am not certain if this makes it the same as the s90's but I suspect it will make the wipers sit better/ lower if you went to this glass ($$).

if you have a pre-89 car then you'll have to chop a bit of metal off the inner fender (no-biggie and volvo actually specifies it if you do repairs there anyway) The newer fenders will then bolt on just fine.

need new headlight, turn signal clusters, grill

Headlight light support/radiator bridge is 1-piece with 95+ 960/s/v90. But I think you can do a hack job to make things fit.

What I am not clear about:

1. If I decide to go the "long" 960 hood, The hinges actually bolts onto a different place in the inner fender (up where the cowl panel is) compared to 7/940. What kind of mods do I need to do to accomodate it (is this the firewall mod?)?

2. The cowl panel should be replaced by the plastic unit like the 7/960/s/v90. does this plastic panel fit once I remove the existing metal cowl panel?

3. How different are the wiper system? can I just shorten the 940 system's shafts and bolt on the 960 style wipers?

4. What is the difference in the A-pillars?

^^^^^^^If you know the answers to any of these questions, please answer!!!

.....Then there's the paint-job, door handles, tailgate handle, door and fender mouldings.....

.....Then if you feel really sporting you can start tackling the dash and interior (95+ doors have different inner panel, door trim and latches)

.....Then if you are still bored you can go to the IRS.

But I think I'll do it anyway. :-D

well ive been scavenging and all i need now is fenders!! then the brick goes under the knife! :badboy:

[JuhaP]

By the way, I have brand new S/V90 headlights, turn signals and grille in stock, if anyone is interested... :wink:

[kevro]

just found an s90 ripe for being gutted, i got all the interior panels, the glass roof assy, the whole front end minus hood, also got the side skirts. any tips on the swap of the sunroof assy would be apprec i know some one in here has it done to a red wagon it seems pretty straight forward but everrything always gets tougher when the car is in parts. I ve also seen somone put the s90 inner door panels in to a 740 any tips on that end would be greatly apprec.
For now ill wait until the az sun cools off a bit and then get some b4 pictures for everyone to admire the b4 and after pics.

strange, today i saw a late model 740 turbo with the wipers in the stock postion but with a 940 front.

2. The cowl panel should be replaced by the plastic unit like the 7/960/s/v90. does this plastic panel fit once I remove the existing metal cowl panel?

In my Volvo brochure for '90 740 and 760, there are photos of the car in its basic chassis framework, and you can clearly see that the 740 and 760's firewall is quite different. I don't think you can just bolt on the plastic cowl panel from a late-760 / 960 onto a 740 / 940 once you remove the scuttle panel, unless you are planning to modify the firewall as well. I can scan and post those photos if any of you guys are interested.

The '90 Volvo 740 Turbo and 740 GLT 16V came standard with 940 front, with black egg-crate grille.

The late model 700s came with the 700 series hood and a 940 front.

[V-Jet]

I posted the image here - http://www.pbase.com/sabredog/inbox

Note the area just in front of the windscreen and the firewall - it's evident that the 740's is different to the 760's. As 740 and 760 evolved into 940 and 960 respectively, I believe they are the same as the 900 series.

The '90 Volvo 740 Turbo and 740 GLT 16V came standard with 940 front, with black egg-crate grille.
Sorry, I should've clarified that I was referring to the European release of '90 Volvo 740 Turbo and 740 GLT 16V...

Okay, when 740 got a facelift in 1990, there were 2 front ends. The "base" front end without fog-lights, also called "Alt-1" and the one with fog-lights next to the grille also called "Alt-2". In fact "Alt-2" was first introduced 2 years earlier on the new 760, except on the 760 it had an aluminium hood while on the 740 it still had a steel hood. The steel hoods for "Alt-1" and "Alt-2" are different, as well as different front bumper and grille.

In 1991 when the 900 series was released, it received the "Alt-2" front end as standard (with aluminium hood on the 960), while 740 lost the "Alt-2" front end and was only available with the "Alt-1" front (960 replaced 760 in '91). Furthermore, the "Alt-1" front on '91 and later 740 now has the same hood as the "Alt-2", persumably to reduce part variety. As a result, the '91 and later "Alt-1" frond end has a different hood, grille and headlight trim panel compared to the '90 "Alt-1" front end.

[WindowsBreakerG4]

OK I know this is a super old thread but I am trying to figure out about changing hood and cowl on a 91 940 to make it a 960/760 lookalike, I like the obscured wipers better and it seems like the aero would be much better. I am having a hard time getting a clear answer on what must me done here to make this work.
