[E85 335]

Heres My Build Story.....

Bought the car last year in March for $25k cash which is a 2006 335i stock standard car with 152,000km on the clock with all services maintained fro a doctor in Brisbane. The paint work was pretty good and all panels when straight with no dents. The bonnet had some marks but I was cool with that. Inside was pretty tidy except the backseat centre console and the power window switches where the coating was starting to peel off.

First thing I did was to get an oil change, new spark plugs and coolant change done. About a month later bought the following:

- CPE Charge pipe with Trial BOV
- T20Map
- Stage 3 LPFP
- BMS OCC
- AFE Sccops
- AMS Intercooler ($1200) Now swap to a 7.5" Setup from BMS
- JB4 ($700)
- RB PCV Valve ($50)
- AFE DCI ($600)
- AR Design Cattless 3" DP ($1100)
- BMS Meth Kit ($700) Dual CM7 Nozzles
- Waterpump
- Thermostat
- O2 sensors x 4 (walkers) - Shit dont get them
- Akabarno ceramic pads with new break indicators

At this stage I was running Stock Turbos and after these mods the dreaded wastegate rattle started. Decided to take the plunge and get new turbos. I was researching like no tomorrow to decided who to go with RB's. I spoke to Rob from RB and decided to go with his product and ordered all options (billet wheels, thrust and clipping). It took nearly 8 weeks later before I received the turbos which sort of annoyed me but hey I got them.

My car took a week to get them installed. The worse thing was when I get a call and the mechanic said that my sump has a crack in it. The original place I took to get the dps installed had put a lever on the sump to get the steering rack back in and cracked it so $1500 later i got a new sump from BMW install.

Once I picked the car up it was a totally different machine. So much spool and power. The first thing I noticed though was a slight tinny ticking sound which was similar to a wastegate rattle. Took back into the shop a couple of times and they could find the rattle. Anyway I will get back to this sound later...lol...

Put the car on the dyno and pulled 430rwhp on map 7 with Terry's e85 flash running meth and 50:50 e85. Was pretty happy since I didn't have custom tune.

Contact Trebila and we started on a custom tune together. Anyone reading this and has a jb4 this guys is the best at what he does so get in contact with him. We started to max out everything and was only 4 days out when I was driving normally to lunch and I heard a pop and then noticed smoke coming out the back. I shit myself but the funny thing is I still had the power but on the safe side i got it towed back to the shop.

- RB Turbos ($6500)
- Sump Gasket

The mechanic did some checks and realised that the rear turbo had movement up and to the side. His words the "Turbine is like a sloppy sock in there". Now remember that sould before from day one..... That what was ticking... Contacted Rob from RB and he said get them off and send them straight back as I had only 1200km on them. We agreed on getting a new set of RB Next Gen's as replacements with all the options since only having them on for a short period. So I got them off and sent them back. I at this stage saw RB was doing a group buy on the new release of there inlets so I decided to buy them thinking they would be deliver in 3 to 4 weeks. Well yet again 2.5 months later after my install I get them in the mail.

It was going to take forever to get the turbos back from Rob so I spoke to Justin from Advan one night and took the plunge and bought yet another set of Pure Stage 2+ and he convinced me to get the TFT inlet system RHD kit since my RB inlets had not arrived so I could continue with the install. I also got the remus race exhaust muffles with quad tips and got the guys to do a twin stainless custom exhaust with 200 cel high flow catts.

- RB Inlets ($550)
- Pure Stage 2+ ($7500)
- TFT Inlets ($2000)
- Injectors Index 12 x 6 ($1000)
- Remus exhuast muffles ($2100)
- Custom Stainless exhaust with 200 Cels ($3000)
- HPFP ($400)
- oil line and coolant hoses
- belt and pullyes new
- transmission filter and oil (not cheap)
- Coils (Bosch)
- O2 sensors x 4 (BMW)
- All gaskets for oil housing etc

Oh Before it went to the mechanic, bought M3 front bar, M3 Rear bumper carbon fiber front lip and got bonnet, roof and bars stripped back to metal and respayed for $2100 and even got a loan car while it was getting done. lol

Now my car once picking it up from the mechanic said valve seals needs to be done cause there is a bit of smoke so come back after New Year and get it sorted. My car sat at this shop getting all the work done for nearly 8 weeks prior to getting the Pures done.

When I started to tune it again with Trebial the smoke got worse and worse. The power was huge but the bloody thing was chewing a litre of oil a day. My friend recommended me to another place to take my car who have been fantastic. They did a leak down and compression test and found nothing. Changed the valve seals and while they were their got them to replace all the valve lifters as a couple were on there way out with a ticking noise. My mechanic noticed oil on the spark plug in cylinder 5 which he was concerned about. thought it might the stem seals but once he put everything back together it was still smoking.

After more investigation the rings on the pistons are stuffed so the head has come off and I have ordered forge pistons and rods from Pure Performance in Melbourne.
- Valve Guides ($550)
- Valve Steam seals ($200)
- Valve Lifters ($849)
- Forge Pistons ($1200)
- Forge Conrods ($1700)
- Bearing Kit
- Full rebuild + head reco ($5000)

If I had my choice from day one again I would have done all forge straight up, then turbos etc after.

Waiting from pistons and rods to be produced which is 2-4 weeks away then we should be back in action.

Total Labour ($10,500 roughly but probably more lol)

Wish list to come:

- CPE Port Injection (Bought this for $2500) 2016
- Wavtac LSD
- LPFP Stage 3 (bought 2016)

DAT you are the mod King. Most peeps take a year or more to do the work you have done. Pure awesome. I hope get the rod upgrade done so you can finally enjoy the car. Awesome build mate!!!

[JB4-335]

One of Australia's craziest 335's.

[DR-JEKL]

Nice build mate, and some serious $ spent!

What have you done for tyre, chassis mods?!?

I was only putting out 270rwkw at one stage and hated the elastic band feeling of the stock suspension! With 320 ish rwkw it was bloody terrible, cant imagine what it would be like with 400+ rwkw

[E85 335]

Cheers everyone. Has been frustrating at times that's for sure. I am running 20x8 on the front and 20x10 on rear. Haven't really had any issues since changing to pirelli's for traction, best choice of tire I believe. Suspension feels great so not really looking to change.

Also some pics of certain progress overtime

Nice build thread A lot of mods and $$$ spent, hope all goes well with the upgraded internals from Melbourne. Might hit them up myself to get some info.

[7smurfs]

Very impressive build you've got there. Shame a lot of it was due to fixing issues but...

[E85 335]

It has been a costly experience but hey gotta spend the money to get the best performance

[iliketurtl3s]

Fastest n54 335 here?

[E85 335]

Nah. There is faster. Need the last couple of mods on the wish list to take that title out haha.. once I get it back I will tune it and throw it back on the dyno and see what she does.

[vtl]

Wow, I wouldn't be able to stand that much power on the stock suspension and open differential.

Will be much nicer to drive once you get that Wavetrac LSD installed. I would highly suggest swapping out the subframe bushings for some polyurethane ones as well. Will stop the car from rear steering under power.

Are you on the gold coast?

Yep

[EB89]

Are those resonators in your exhaust?

[E85 335]

Nope 200 cel catts I need them though cause the car exhaust is way to loud and drones when on the highway

Ok, fair enough, hows it sound now with those in? Any videos?

Firstly, twenty five f*cking thousand?!?!???!!!! Fuck me in the beeepppppp...... That's super cheap!

I know there's a couple of built n54 motors out there in AU, but none of them documented online, till now...

Will be interesting to follow how you go with it all and how the motor handles it.

[E85 335]

Yeah I am looking forward to seeing what power it produces and how far I can go. Probably won't do the additional wish list till after July but you never know I might have some spare cash once I get back from Italy in may. I have some other pics I will load and also I am heading tomorrow to take some pics of the head off and what it looks like.

Is there a danger that the engine might implode at these power levels Inky?? Or will the transmission or gearbox clutch need upgrading above 500 hp?? I would have thought the drive train would fail before the motor

[E85 335]

Motor will be solid. Tranny might be an issue but if the tune is correct that should be ok what I have seen on the forums. Mines an auto aswell.

Sweet apparently there is a group in Mellb working on a transmission upgrade but looks to be pretty expensive 5K plus from memory !!!
