Good idea. Fine engine, the 1.9 - based on the one BMW used to build their 1000bhp Grand Prix motors

Which is the point made above by WCA, Smash and Mr T, and is why Richard has commissioned special lower offset spline adapters. But even so, you're going to need extended arches or a narrow rear hub conversion of you want to fit wheels with a large offset.

I'm sticking to my guns on this. Its the way I have always worked out wheel fitment , it can be calculated both ways .
You can only go so far with the hub adaptors. You have to look at other options if that still isn't enough.
It wouldn't be too difficult to narrow the axle on the Z3. The mounting points for the rear arm could be moved in an inch or two. Along with a short drive shaft you could easily fit the 6" Cobra 289 wires.

Must not bite, Must not bite, Must not bite, Must not bite, Must not bite, Must not bite, Must not bite...
Damn it, I can't help myself
Fine engine, the 1.9 - based on the one BMW used to build their 1000bhp Grand Prix motors
The Hippo and the Horse share the same basic starting point, just like the engines in a 1.9 Z3 and the GP motor...

HaHa, you were resisting it so well for a while ;-)
But don't forget that the M43/44 series motor that you so hate so much is based on the M10 which derived the M12 Grand Prix motor that produced 1500bhp or more (there wasn't a Dyno available in the 80s that could measure more than 1500 horse) in qualifying trim from 1500cc!
Info here if you could care less

Good for you , and of course you can calculate it from the backspace dimension but it's not a sensible way to measure the poke of the wheel, particularly as you have to take off a wheel and physically measure the backspace from the hub mounting face and then subtract this from the overall width of the wheel to find out how much it pokes out!! Backspace is used to measure inside clearance.
The ET and wheel dimensions are cast on the wheel so no measuring is needed using the method I suggested!

Get a grip! This can be much more easily done by replacing the rear hubs and drums from our beloved 2.8 cars with those from the hateful 1.9.

Reason: Deleted E30 as it has 4 stud hubs except the M3

I seem to recall seeing an early 1.9 with an E30 325i straight six grafted in on ebay recently. I think it sold for about £750.
Could be an option worth considering: MOT failed 320i or 325i plus engine blown/damaged/missing Z3 1.9 = cheap donor for 250SWB + pile of cash from selling off unwanted parts from both cars.
And hopefully no hate-mail about your engine choice...

I thought we were all being nice to each other now!
I'm not sure if the 1.9 conversion would give you enough space or not.
Yes you could convert the 1.9 to a straight 6 but it would be loads of work by the time everything is connected up. Just bite the bullet and buy a straight 6 from the word go!!

Can i just confess that I don't care what car or engine anyone uses. Richard's better half (Nubodi) has a lovely 1.9 Z300S.
I base all of my prejudice and bile on a couple of back-to-back tests when looking for donors plus a load of internet banter and alcohol*.

*I have decided to cut down my drinking for January to pay for the paint job on my Z300SWB bonnet. This explains my confession. Normal ranting will be resumed when I am back on the booze.

Didn't mean to upset you, just offering another way to do things
Importantly, you don't have to listen as your opinion is equally as important as mine. Though mine is better

That's what powers the Internet At least you've done back-to-back testing which is more than most do before professing hatred, prejudice and bile!

Well SNG Barratt, whilst exclusive UK dealers for Dayton wheels - they actually only do the Jag ones and then only splined, not the bolt ons.
Turrino came back and quoted....£850 plus VAT per wheel for bespoke but said most economic would be start from "stock" jag and machine the spiggot so we'll see what the price comes in like.

Have you asked MWS to quote for building you something bespoke too? In my experience (of looking not buying), they'll be cheaper than Turrino - who appear only to do chromed wheels/

Sorry, should've made myself clearer - the suggestion to fit a straight six into a 1.9 was in response to a question about narrowing the back end to accommodate splined wires while ending up with a car with the (more desirable) six cylinder motor rather than a criticism of the 1.9 engine.
Despite the obvious risk of it all being a bit of a ballache, I have a gut feeling that changing a 1.9's engine (and gearbox?) for a six pot is going to be easier and more likely to have been tried and tested than swapping the rear axle assembly. After all, there are a number of Z3's on you-know-what-tube running BMW or American V8 motors if you must have the full wind in the ponytail experience. Just watch out for the ground clearance and traction on your kitchen floor issues it creates though... -

Mind you, I still think a six pot sounds better.

Turrino have come back on their "stock" jag wheels
We can supply the 7 x 16 Jag bolt on wire wheels for £310 + VAT in chrome, or £410 + VAT each in stainless. They have an inset of 22mm.
So actually slightly cheaper than MWS.
Third email attempt to Dayton....

That sounds like a good price, and with an offset only an inch more than standard they should fit within the arches.
I had a quote for 17" wheels from Dayton about a year ago that was more than the Turrino quote. I'll see if I can find it.

Found a quote from a March last year for 7x17" Truespoke with spinners - not Dayton as I thought - at $650 each plus carriage from the States, so Turrino sounds cheaper.

Well I've taken a deep breath and amended my excel spreadsheet to budget for 2k on wheels - at the end of the day they're a massive part of the overall appearance and impact of the vehicle.
I am however, no longer scrolling down to the total at the bottom!!
