Need some advice on My New Project Car

Recommended Posts

New to the forum and need some advice from you volvo loving gurus. I was looking on craigslist for a comfortable familyish project car and ended up buying a 2006 S60 T5 with the m66 6 speed. I got a screaming deal on it because it has a broken timing belt. I didn't know how awesome this particular model was until i started doing a bit of research. That led to the desire to do more then just fix the bent valves. While trying to find a good used head (not easy to find on this dual cvvt model) I stumbled across a wrecking yard 2 1/2 hours away that has a 06 s60r. I started thinking about what upgrades I could salvage from it and decided to go get the brakes, bumpers, and side skirts. I get there and the side skirts are gone and the rear bumper lower trim was missing so i decided to bail on the body parts. The salesman I called in advance to make sure the parts were available felt really bad amd said "I'll make you a good deal on whatever parts you want" I decided to take full advantage of this and ended up with the following off the s60r: Calipers, rotors, Instrument cluster, steering wheel and complete motor (suppose to run excellent). Total investment at this point $1600 ! Im trying to decide what to do next. I would like 300hp to the wheels but the tune and supporting mods are a bit pricey and at this point im thinking i would like to get it drivable for under 1k additional budget. I'm thinking of ordering timing kit, clutch kit, mt90 trans fluid, high flow Down Pipe. I want your opinions of what would be best to do with budget in mind. I'm unsure of how much HP the stock replacement clutch (30783259)can handle. Also i leak down tested the replacement s60r motor and the valves are sealing amazingly well but 1 cylinder has 25% loss past the rings. Wrecking yard said they compression tested it and it was 140 psi across the board (I call bs). So i start looking the motor over and checked the low cylinder with a boroscope and it looks beautiful! Super nice honing marks still with no visible scratches. The oil looks like 10k used diesel oil (super black). Im thinking the lack of maintenance may have caused buildup on the rings. Im currently soaking that cylinder in marvel mystery oil hoping the may fix the leak down results on that cylinder. I've never been interested in volvos (uncommon cars where i live) until this purchase. So after 2 weeks of reading these boards my brain hurts. All that being said what would you guys do? I realize i wont get the car where i want it with only 1k current budget but i would like to make it easy for when I've got the cash for the tune and exhaust.

Wow, nice find! The T5 M66 is a pretty special car for sure.

You're definitely on the right track as far as maintenance goes. The 2005-2009 T5 engines are known to be some of the best 5 cylinders Volvo made, and that would probably be the best for making big power on stock internals (the crank and the rods are forged). 300 WHP should be achievable on the R motor but I'd definitely hold onto the original engine if you ever want to go beyond that without tearing into the bottom end.

I can't say much for the clutch, but I think the stock clutch can probably hold up for your power goals. There may be an upgraded Sachs clutch available, but I can't say for sure.

Do you think i should just steal the R Head and throw it on my existing bottom end? Or run the piss outta the R motor and rebuild the 2.4 on the side?

That could be a recipe for a really good setup, but I'm not sure of the differences between the R and the T5 heads. It may be an improvement, but it could also be worse. I couldn't say for sure, that's something someone with more experience with these particular engines could probably answer.

I'd probably go with the second one. It'll make it nice and easy to drop in the R motor, then when you can take your time to build the T5.

I think this year T5 already has the R head. Just get one spark plug out and measure the thread length

The spark plugs should be the same longer thread in both the 2.4 T5 and the R.

Some dope put those plugs in my 2000 V70R... it was a fun time taking those out...

Love me a good t5, if your budget is under 1K do a vacuum test and replace any PCV parts at the mileage it's at.  Self-done it's under a 300 dollar job. 

Also replace any vacuum hose, sparkplugs, and trans fluid drain/fill.  Make sure to use mahle filters, do an oil change and a fuel filter change as well.  Check the transmission and engine torque mounts - they're both about 20 bucks and easily done yourself.  If you can move the top bar across the engine with your hand, the top engine mount needs replacing, and in my experience so does the trans mount at that point.

Furthermore, for a 1k build check the tie rods/balljoints/dampers.  Get bilstein b4 if any of your dampers are monkeyed, and lemforder for anything else.

Good luck.

      timing belt already done
      its immaculate, i cannot believe i got so lucky.
      Besides changing all the fluids, what should I pre-emptively take care of?
       
      I'm already balls deep watching shifting lanes on youtube and moosetech who work on c30's of the same chassis model. 
       
      Thanks

      I wasnt sure where to post this exactly, but i figure some of you might appreciate this. if you where at ipd last weekend, you might have seen me there!
      I havent started a build thread for it, but i am making a whiteblock swap thread over on TB right now including this project. 
      98 t5 block, custom clutch disc for a foxbody t5 trans, motronic 4.4 with COP and wideband lambda, stock trimmed harness, cut 960 pan, custom mounts, toyota alternator. i dont have a solid video of it yet, but i figure this weekend after i get the exhaust on it and the wideband hooked up, ill see about making something.

      Hi everyone, just joined the forum and hoping I can get some help😁Just purchased my first car, a 94 850 T5 and looking at some different wheels. I had a quick look on here and people are saying that 17x7 and around a 38-40mm offset is the most you’ll be able to fit on an 850. Currently I’m looking at these V50 wheels, the issue is that they are 17x7.5 and have an offset of 52.50. I really quite like them and for $400 for a set of 5 it seems like a good deal. Does anyone know if I can get these to fit/what modifications I’ll have to do? Also, I hear something about late model wheels not fitting because of their hubcentric sizes or something?
      The tires on them are 225/45/17 if that helps, I read 225 is as much tire as you can get on an 850 aswell. Any help is appreciated!
