thinking turbo?

[TheJKS]

ok ive done the reasearch and realize turbos the best bang for your buck when it comes to performance. but i am by no means a gear head so i have a few questions for you techs out there ,if i were to turbo my 6 would there be any other parts i should upgrade in my engine i have about 210000km on my m30 i wanna do a rebuild at about 250 or 275000km, what componets would be weak and liable to break under a turbo?? or any parts i should conisider to achive more power from it?? im gonna go with the tcd kit only because i can buy stage 2 an add it later when my money is right. also im gonna lower my 6 with eibach springs and blistin sports thight the chassis with strut bars front and rear ,but i was woundering if there is any other componets like with the steering drive line or any thing anybody would recomend?? this is probally gonna be a three year project for me im getting it painted over winter and by spring it will be lovered with a set of 18" rims, then i plan on putting some money in to getting my baby ready for a turbo:buttrock
all help would be great like i said im no mechanic well actually i am a refridgeration mech/gas tech but the only skill i can use from that trade is gettin my hands dirty haha.

but anyway thanks for any input i will appriciate any an all help

Better brakes would be a good idea, and being fully caught up on all upkeep (like having every fluid changed, like trans, diff, etc.) would help preclude some failures. The TCD S1 kit is fine to start, but since you are already going to go stage 2 later, power-adder options added inbetween could mess up the tuning that TCD provides.

As long as you have good compression, your motor should be fine. If you want to do some preventative work, a new head gasket (unless there is a relatively new one in there already) would be a good idea.

Everything else on the 6 has been tested in the E28 extensively., so nothing should go terribly wrong unless it was already a problem.

if you're running an automatic,if there is a weak link there,it will show up with the added torque.also all mounts from the engine to the diff should probably be replaced.you will adding extra stress with your new found torque.i've had a couple of turbo volvos and spool up is great.that's when they really start to pull.an intercooler enhances turbo output.

Brakes and suspension. I've seen several auto 635's w/ Turbo. Talk to the guys at http://www.turbochargingdynamics.com

Internal engine changes should include lower compression pistons, or you'll be forced to run much lower boost and you'll need to install a waste gate to avoid over-boosting your engine and blowing a head gasket...or worse your engine.

Springs, shocks, swaybars and brake upgrades (as others have mentioned) are always nice when you add more power! Remember, power is nothing without control!

Have the turbo installed AND tuned by a person that is experienced, doing otherwise will most likely be a HUGE mistake!

Not with the M30. The highest compression M30 was the M30B35, which (in the US) had a ratio of 9:1. This ratio allows safe boost up to about 14psi on stock everything, incuding the head gasket, which is sufficient for more than 360rwhp.

The TCD kit comes with a wasegate. The stage 2 kit adds an intercooler to help prevent detonation. Also, the TCD kit comes with a proper tune, but true, additional tuning always helps.

i got a 86 5-speed so i shouldnt have any tranny problems, i shouldnt add nothing to the engine preformance wise? just do a rebuild?
i should replace all the bushings and mounts.
thighten the chasis sway bar front/rear.
tighten the suspension.
what brake upgrades do you guys suggest ive heard of the 740/540 set up but are there any after market that look real nice thu a set of rims?
how bout steering is there any parts that will need to be beefed up ?
thanks for all the input , i appreciate all the help
i just wanna make sure my 6 can handle what im gonna do to her i wanna own her another 20+ years , and it would be a shame just to drop in a turbo with out properly setting the car up for it and have some thing break at high speeds sendin me and my 6 to the graveyard.
thanks again

The only reason to do a rebuild is if you have poor compression. Considering the majority of M30s now have more than 100k miles, and most of the TCD boosted cars are not rebuilt, it isn't that big a deal, and will save you some cash.

There are a ton of E28 brake upgrade FAQs online, take a look for them. They offer the best band-for-the-buck solutions for more braking. There are additonal Willwood caliper/rotor sets, made by UUC and Ireland Engineering. Brembo kits are absurdedly expensive, almost as much as the TCD stage 1 kit. The UUC/Ireland kit still runs about 1k. Finding some OEM 750 calipers/rotors is the cheapest and best value way to go. Steering won't be a problem. You will need a better clutch, search around the FI section for the clutch options.

Racing Dynamics sways are good, and I personally like the Bil/Eibach suspension combo. There are a multitude of E28 suspension FAQs around; take a look.

If you want to know what can break, as over on the E28 forum, as that is where the majority of TCD owners are.

alright thanks for all the help im gonna check this out.
