1M power and cosmetic mods

[Rajvosa]

hi all,

new to the platform and have done lots of searching but wanted to check few things with you all

1) carbon boot spoiler- other than genuine, any other proven ebay etc items that fit good and look good?

2) i will be doing few power mods in the coming future, and have decided on a minimum:
- downpipes (any major brand is fine im guessing?)
- MHD tune
- aftermarket air intake necessary?
- is an intercooler necessary? its a weekend toy with ocassional light track day. not sure i need to add intercooler just yet (i know its good to have but is it a necessity?)
- other than those above, any other mods worth doing to free up the power?

thank you all

on the 1m the down pipes are not necessary on stock turbos

Custom mhd tune is best

air intake is a waste of money, no gains to be had below 380 rwk

Intercooler is a must, best one for stock turbos Wagner Evo comp 2

thanks for advice

out of curiosity why arent downpipes necessary? are 1M high flow so no need to swap on stock turbos?

who can do custom MHD tune? rough cost? so if i just add mhd tune its stage 1. and if i add intercooler, does it make it stage 2 tune?

thanks for advice on intercooler. i was looking at 7" or 7x5" vrsf ones. no good?

[martymil]

Get the mods you want and custom tune last.and cost depends on tuner

The vrsf ones are good but extremely heavy and if not racing unecessary
A good wangner evo comp 2 is far better suited for street and light track day

Down pipes in 1m's are high flow and there is limited gains in terms of power changing to catless ones whilst using stock turbos

Hey mate, I went with a CF bootlid spoiler from 'JBSpeed' that is a rep of the OEM offering.

Ive had it on for about 9 months and am very happy with the look and quality.

Approx US$220 delivered...

Yell out if you want to have a look at it, or come along to Targa West on Saturday or Sunday!

Cheers.

[martymil]

Talk to jd75 on these forums he can supply wagner and vrsf

[Rajvosa]

Hey mate, should have looked at it when you came over haha

So fitment qualify is good? No bad gaps etc? Carbon weave is decent? (I know it's a rep but still decent enough). Should probably have a look at it one of these days mate

i'd second what martymil said. a few extra points;

the stock IC is near useless in Perth summer, running 98. 98 is rubbish fuel and even worse with increased IATs. when my car was stock i used to get timing pulls on the ppk flash (similar or same power as 1M). i have the original 7" VRSF. It is heavy but good value for money.

w.r.t DCIs, for daily driving (and again on 98) they are probably worse than the stock airbox, despite what numerous threads would say in my experience. on track they are ok because the engine bay sees more clean air.

regarding cats, the other benefit of retaining your cats is that you will be less annoyed with wastegate rattle when it inevitably starts, if it hasn't already.

if i had my time again, the first two things i'd do would be a good IC and run ethanol mixes (i say mixes so as you are not up for fuel pump and ancillary fueling straight away). Like E20. Then a basic low pressure fuel pump upgrade so as you run ~E50. If you live south of the river then E85 access might not be so practical.

did you have that E46 M3 i saw earlier this year? no back seats? might be confusing you with someone else.

Red or blue?
He's an M tragic and has gone through quite a few E46 M3s haha.

honestly cant remember, i want to say blue. but it could have been red... had bucket seats.

have you got the new motor running?

[martymil]

I run 350-360 rwk with 8 deg of timing and no timing pull most of the time on 98 but sometimes I add a bottle of nulon pro strength octane booster when I do get it

The days of running meth and e85 to make decent power are gone with the current tunning available.

we are talking about his stock turbo's.

[martymil]

Stock or not with current tuning technology you dont need e85 to get the most out of them, yes on e85 you will get a little more but it comes at a price, more frequent maintenance and almost 30 to 50% extra fuel usage and its a pain in the arse

He can get the same power output on 98 as e20-30 when tuned correctly without the extra associated costs

Blends are a pain and pointless, either go one or the other

[JB4-335]

Meth and E85 FTW!! Sorry Marty. It's just a safety blanket for me. My car use to haul ass on a good combo. I do agree it can be a pain managing it all but I never minded.

I use to run 20psi on just 98 back in 2011 with the occasion octane booster but it's can be risky if not tuned correctly.

[martymil]

98 is not risky at all on our cars as long as your not running to lean and the ecu will take care of the rest with the current tuning capabilities

Tuning in 2011 is not the same as now, its come a long way

Meth is not safe and neither is e85 in the current way its integrated and running on our cars, the only way e85 can be safe if its di only.

Just because you had no issues dont think you are safe from a di shutdown

If you get a di shutdown and you melt a piston from a hyperlean because meth and/or e85 is still flowing you will wished you listen

But its your call if you think the gains are worth the risk, at the end of the day its your money.

Hey mate,

You can buy the genuine BMWP Carbon spoiler out of europe on ebay genuine and rather cheap now, along with the genuine tape it will fit perfect, for the sake of a few $$$ maybe get something that will fit perfect. Black grills are also found on ebay pretty cheap and genuine.

If this is the 1m im thinking it is from qld id probably get a walnut blast if you have never had one done on there car at 100,000ks. my motor at 20ks was filthy. before and after driving the car was night and day.

i modded my car all at once, turbos, intercooler, downpipes, intake and tune. im left to do fuel pump and a retune soon. you will love the car with a little more boost.

[Rajvosa]

Thank you all for the advice. Being my first turbo bmw (or any turbo for that matter) I'm still at the learning stages of the platform.

I am not after trying to squeeze every single hp possible at the cost of maybe damaging engine etc. I just want to give it a bump in power safely even if it means leaving hp on the table.

So running a IC and mhd tune on usual 98 fuel would be a good start right? Then I can get someone to further custom tune it if I choose to.

Thanks for that mate

Yeah it's the QLD one. Have been getting in touch with workshops here in Perth enquiring about walnut blasting. It's definitely on the go do list asap

[martymil]

A good ic and a custom tune will maximise you stock turbos on the 1m to around 90% of their max effiency and thats as far as you want to take it from a reliability standpoint

Also change your charge pipe and upgrade your clutch to a 550i one as soon as you detect slip

Now you will have a reliable everyday or fun weekend car that will last you a long time

[Rajvosa]

The previous owner put a new OEM charge pipe recently but I'm guessing I should upgrade.

Do I need to run a BOV or can I keep stock set up but just change pipe?

[martymil]

If custom tuning I would upgrade them because they can leak over 18psi

Dual plumb back turbo smart dv is the way to go on these cars

and if your going to tune you will have to upgrade the charge pipe as it will disintegrate eventually, they all do even when stock

[Rajvosa]

Cheers for that. !
