Researching "Phase 3" on the Z4 advice.

[Machine monkey]

Jonny woots is 100% correct hear I have said it before V8 or V10 all the way buddy

My mate has a e30 with a V8 it's mental

No idea what I done there???

 

[Woots]

Stevie w did an M5 V10 conversion.

I still reckon, buy a Silver MR MC :evil: and go to town tuning that....

He won't sell his car, we've established that....so next best thing is to fit a v8/10
And I'll almost say it makes sense if he decides to fit a truly epic engine into it!

I'd love to find a really old zed for cheap and rip the engine out as a project! If I was rich obv!

Make me an offer or we could do a deal on your car woots???? Mine has a LSD coilovers Polly bushes all ready for track and modding fun????

Haha thanks bud but sadly if I get rid if the ///m it'll make way for a company car until I've paid off divorce stuff...then when I've reset myself I'll get an Italian v8

You can buy my car if you want tho

 

[Woots]

Jonny woots is 100% ore cat hear I have said it before V8 or V10 all the way buddy

My mate has a e30 with a V8 it's mental

For once I'm talking sense...

Keep car as is
Keep car and go epic engine
Sell and buy an ///m

Would love to see a corvette V8 in JE's Z.

I can vouch for Corvette power. Mines a Z06 comes with the hand built LS7 engine, 7.0L V8 with 505 BHP.
As standard the thing pulls like a rocket, these engines have so much torque, hence the 335 rear tyres that are needed to hold things in place!

I've spent a bit on this lump and we now have it up to around 760 BHP. These engines are born for tuning...

Jonny you keep talking about a 'M killer'.. how about a Ferrari, Lambo, killer for a bit more budget!

Here's my baby:

Yes she's in the UK now. I have a home in Texas US too and often buy and import American toys!

Here she is in UK..I'm currently eyeing up the new Corvette C7 Z06, so this one may not be around for much longer:

 

[Woots]

Awesome buddy!!!

Bet it sounds meaty!!!

If you are serious about your £15k budget there's a V10 engine on ebay for 6k http://www.ebay.co.uk/itm/06-BMW-E60-M5-COMPLETE-S85-5-0-V10-ENGINE-CAN-BE-HEARD-RUNNING-STILL-IN-CAR-/271464705876?_trksid=p2054897.l4275

That WOULD be a show stopper, the final word in Z4 modding and shut those who are calling you out. Or just go for these

Jonny if you bag it, I'm near South Wooden Ferrets next week and will gladly buy you a pint!

 

[domsz4]

mmm that v8 barble is great and can snap knicker elastic at 50 paces, you dont even need to drive it... just turn it on and listen to it cough and splutter.

 

[Mark-Z4]

I can't wait for 'Phase 5'......

 

[Adam D]

V8 with sport button?

So I'm probably going against the grain a bit here and suggesting you go for the 3.0 and supercharge it!

I'm going along the same direction and my inspiration is this by Simpsons -

http://www.simpsonmotorsport.co.uk/default.asp?id=77&pid=70&name=BMW+Z4+3.0+Supercharged&page=Projects

To be honest a 3.0i modified with some good coilovers, brakes, LSD and some good rubber will be as dynamically good if not superior to a Z4M.

I've recently had corner weighted AST's, Ksports with RS29's, R888 on forged Ultraleggera (without a doubt THE most noticeable upgrade for the car, the R888 almost wiped out the fuzzy steering feel) and pretty much a whole bush refresh on my Z4 and dynamically it's on par with my M3 running KW's, AP's a whole load of other goodies. Both cars have a track orientated setup with a Z4 being a bit harsher on public roads (AST spring rates need fine tuning) but the response is as good as the M3 and probably better than a stock Z4M (I don't have much experience with a Z4M but I know I preferred an M3 over one!)

My thought process was that supercharging the Z4 and blowing a couple of engines on track wouldn't be a big deal considering M54's a two a penny. Having an M car already I wanted to see how far I could take a non M with bolt on parts.

If you were that way inclined I'm sure you could remove the parts and sell them on separately when you're done with the car.

Stock v stock no doubt the Z4M is the more exciting car but once you start going towards the end of the tuning spectrum the difference is negligible.

It really depends which way you want to take the car, if you want it to be a compliant and predictable sports car I would advise against coilovers, stiffer anti roll bars and track orientated brakes because you won't like it much and for road use you'd get a much better performance/usability tradeoff with less focussed parts. I'd go bonkers if I had to drive the M3 or Z4 daily! I wouldn't be without my XFR or the dog mobile A6 3.0T for daily duties!

 

[srhutch]

Simpsons got rid of that car a long times a go. It was bought by a forum member after they returned to stock.

+1
I was just going to say the same thing... I see if i can find the chap that bought it... And it was completely bone stock.

Johnny, your z4 is in pretty much showroom condition, engine swaps open up a can of worms for reliability and all that and then factoring you're considering f/i as well, I know I'd be pretty gutted if I had to read a number of threads regarding that.

If power and forced induction is what you're after, why not get yourself a cheap e36 and turbo that up. There are a number of people running boosted 328 with relatively little effort and at least that way your Z4 stays true to it's nature of being OEM.

Plus parts for an e36 are significantly cheaper and more readily available (strengthening bars, suspension, big brakes etc)

 

[Zeld4]

Hi JE, I don't know of it's already been reccomended but why don't you go for the three litre turbo they put in the 335i and old 135i? These engines are easily tuned to 380hp just with a remap and with the torque in a straight line you would be able to destroy most things on the road! Also it would drop straight in to your car!!

I think it has been suggested and I agree it is an intriguing idea - it means you would be making something that isn't available from BMW and brings FI right out of the box. However, I imagine engines are a bit harder to come by and not cheap? I'd also question your "drop right in" comment ... are you sure? Has anyone done it?

 

[jimmybell]

I said this a few pages back, JE is basically bringing the E85 into the modern age by improving styling and handling, may aswell bring in the modern engines that are smoothly turbo'd from the factory, and yes - JB4 will bolt on ~80bhp with the learning map.

 

[Babw]

I'd be interested to know the N54B30 does fit into a an E85/46 and able to get it running without major engine management upgrades i.e Pectel or Motec.

If you want to increase performance then the proven ESS twin screw kits will give you plenty of go and a fraction of the labour costs involved with sourcing, fitting and tuning can be put towards making the M54 flow a bit better and strengthening the bottom end while it's off the car. You're in the perfect position because all the 3.0 engine work can be done while the engines off the car as ESS has proven tunes so you know it's going to run well without any major headaches. Tuning is the key part of any major engine upgrade as you probably know.

There are cars running north of 450bhp running the ESS kit with safe boost and road useable which is enough surely?

(I had a new 335i coupe with the N54, I traded it for the M3 after being stranded in Austria when the high pressure fuel pump went.)

The last paragraph contains possibly the most informative piece of advice on suspension tuning that I've seen on the forum, I used to prep' club road-rally cars and the thing you learn fast is that low weight, a stiff chassis, decent compliance and well controlled suspension travel = real-world cornering and traction on the road, not just lower, wider, stiffer etc ask a Lotus engineer, spot-on
