[QUOTE=C6C6CH3vo]What procedure, 'remove and replace cams' or 'remove and replace Hotside' is more demanding. I know the hotside R/R difficulty can vary alot from car to car depending on stuck threads - just think upon average.

I ask because I'm about to install a Hotside and want to know what to expect compared to cams. The cams were easy but lengthy for me (I milked the process for a day). [QUOTE]

Thanks for the answers below guys. Now another question:

Will the 10.5 hotside lower my 1/8th mi time about 0.1 - 0.2 sec?

Thanks

 

If the cams took a day then the hotside will take you 2.

Actually, as long as the O2 comes out and you have new studs for the hotside it is really not that bad. It is just kind of a pain in the as$ to do. I would do cams over hotside any day. The part that sucks about cams is bleeding the lifters, they just take too long to do all 16.

 

hotside is more difficult IMO

 

Would this be true even for someone (me) whose never worked on cams/head before?
I can wrench a bit, and like DIY-ing, but kind of intimidated by the work around the head. I'm getting ready to do my 10.5 this week.

 

I just pulled out my turbo sunday for repairs. Had to remove downpipe, starter, lower IC pipe, radiator, airintake, exhaust manifold, and the oillines goin to the turbo. Took a whole day and a lot of frustration when a couple studs got stripped. This was my 2nd time pulling it out in 1 month. Never again until i have a new major turbo upgrade to install. Make sure you have 2 days to work on your car if this is your only daily driver. Tools you will need, 2 jacks or jack stands, antifreeze, new bolts and studs probably, some real heavy duty tools, and some back pain killers. Good luck on your install.

 

true, but it is worth every second of the time it takes...........I know this from experience

 

I'm debating on if I will swap the hotside with the turbo still hooked up or pull the whole blasting setup out and do the swap on the bench.

If I decide to pull the whole turbo for the hotside swap, what else needs removing and disconnecting?

 

IMHO, the hotside is more of a pain in the *** but the risks of screwing up your motor internals are greater with a cam swap.

 

I would say the 10.5 hotside is probably an easier swap than cams, but it is a hell of a lot more frustrating because of hard to reach bolts! Do not pull out the entire turbo its much easier just to loosen the band that connects the two sides together and disconect it that way! The hardest part is getting the heat shield off, and getting the 02 sensor out. Just make sure that you have 2 new studs to mount the 02 housing back on. Don't waste your time trying to get the old ones out...its a pain in the ***, and its also easier to mount the exhaust manifold back on with 4 four bolts into the hotside in stead of 2 bolts and 2 studs!

I hope you are doing an o2 housing and a hotside together....that way you won't have to take it all back apart later on if you decide to go with an 02 housing!

 

What is the torque value for:
Exhaust manifold bolts
The four bolts/studs on top hotside
The five O2 housing bolts/studs
The O2 sensor
The hotside/turbo body banded clamp

I asked santa for a factory manual but I dont know if I'll get it because I was naughty as hell this year and bought a hotside, so I need these values

 

Bump

 

bump again...

 

1. Exhaust manifold bolts 22 +/- 2 ft-lbs typical (M8), 36 +/- 4 ft-lbs for big ones at each end (M10)
2. The four bolts/studs on top hotside 38 +/- 3 ft-lbs
3. The five O2 housing bolts/studs 44 +/- 3 ft-lbs
4. The O2 sensor 33 +/- 3 ft-lbs
5. The hotside/turbo body banded clamp can't find this one, sorry Although it's probably not spec'd.

Hope that helps. These are from the '03 international version of the manual. Don't ask how I got it

But the values for the exhaust parts should be the same. Good luck.

 

Sweet. Thanks, Grog.

 

Here are the torque specs in another format.
