The control arm ones take that dead spot on the steering wheel away. Such crisp steering response.

Interesting article but a bit too theoretical. Real world experience with my bushings have been 95% positive (sway bar bushing gave out last year).
Thanks, looks like a spring time project.

Nice car.

But, on what planet is 15C a heat wave? I don't even like to get out of bed when it's only 15C, and I'm not even really happy if it's under 30C :D
I booked the appointment a few days in advance, the temps were averaging 15*C, but on the day of the run it was 34*C :eek:

Requirements:
Down Pipe, Cat-Back Exhaust, Front Mount Intercooler (FMIC), Larger Than Stock (Typically Hybrid) Turbo, Upgraded Injectors, Upgraded MAF
Additional Requirements:
Stock TCV or upgraded Pierburg valve. (Note: A MAC control valve or equivalent is not compatible with this product. If you are using one of these valves, ensure it is replaced with a Pierburg unit prior to tuning.)

Recommended:
Methanol Injection
http://hiltontuning.com/product/stage-3-tune/

My current setup consists of:
TD04HL-16t w/7cm^2 ex. housing‎, 11 blade compressor & turbine wheels
3" Downpipe w/high flow race cat.
EST Catback
Upgraded stock mount intercooler
Blue Injectors
IPD full line of intake and charge air piping
Manifold & Throttle body spacers
6"x8" Dry flow cone filter.

I haven't started data logging yet, so I may need more parts, but my current set up has most of the requirements except for the FMIC, mine is a upgraded stock mount intercooler. If I have problems with IATs (which I haven't so far), then I may sell this unit and go for the FMIC.

Also my "larger then stock" turbo isn't that much larger, it is a TD04HL-16T, there are other who have larger turbos on similar builds. If I want more some day I'll go for the 19T, or even 20T conversion. Gotta leave some room for upgrades :)

NICE! I'm still trying to learn these Volvo Turbos and what is what and what is equal to what power ratio.
16t? No clue. I don't even know what turbo is on my car :( 2002 V70T5. But its Autoi so I don't see me going nuts with Power adders. Possible a one up - upgraded turbo. TD04HL is a MHI turbo. I do have a MHI TD05H-20g siting in a box. I don't think my Auto V70 would handle that too well if I was to find a way to make it fit/work on the Volvo platform. I had it on my BTA4Avant.
I'm going to look into the stg2 tune by Hilton.
This may help

I think your model came stock with the 16t, but I'm not sure.

IIRC dougy has a 20G on his S60R, could look up his build thread for more information on how he made it work. A 20G should be ok, it all boils down to the tuning.

Rob at Hilton tuning discovered it and was able to tune nicely to the boost creep and the only reason why it worked out is my target boost of 22 psi is not lower than my 20 psi boost creep...

Missed out on that thread... So I guess my original statement is true, it all boils down to the tuning :D.

Is the next dougy mod a external WG, or keeping it the way it is being that the creep is acceptable? I always find your threads/posts a great read!

So I thought I'd post up some early experiences with the current Hilton Tune. I've not gone for any power runs as I'm waiting on a fresh fill with 94, but it does run well so far. Also with the tune the idle limit has been bumped up to 750-800rpm :thumbup: which feels more stable and less vibration with the poly mounts.

Anything is possible, but first I'd contact a tuner to see if they can tune that turbo with your setup, but I don't see the 20G posing a problem other then the one dougy has stated.

Also I've posted some information on you question thread pertaining to you motor and possible other sites you can mine for information. Good luck with modifying your Volvo and keep us posted on your progress.

Yay...

So I've got my car at my trusty Volvo indie to get:
- The steering rack replaced along with the lower steering U-joint (the U-joint is more of a why not)
- Front and rear control arm bushing replaced
- Spring seats replaced
- IPD Sway bars installed along with IPD end links

It's unfortunate that my steering rack needs to be replaced, it's the last thing I thought would go on this vehicle so soon. I wasn't leaking, the bushing on the PS side of the rack had worn and was causing a vibration.

Normally I'd like to take a job like this on myself, but I cannot do this on jack stands at this time of year, and my mechanic friend with a hoist is swamped so I can't book the time with him.

Angle gear is fine, oil had migrated from another location from the previous oil change.

Oh well, at least while the subframe is down it's a great time to get the swaybars installed. Everything else looks in great shape, and the shocks are still working properly, so hopefully this is the last service I need to do that is suspension/steering related for some time.
