I'd still skip that middle step. There's no reason to risk it.

Finished product sure looks nice though! Keep us updated on how well that paint holds up. What did you use?

blocks get media blasted all the time, you obviously only do it when they are completly stripped but still alot of people do it, but ive never had a whiteblock that needed anymore than just a hot tank, i just spray them down reallllll good with laquer thinner and use an air nozzle, as long as i spray it right after all the thinner dryes i never have a problem with paint sticking perfect

[ozzimark]

I guess I am being a little insane I'll change that then, no sand blasting, ever. Or glass beads. Most other media isn't a problem.

I used what they had at the local parts store. I think it was Duplicolor engine paint, with a coat of clear on top. We'll see how it holds up.

Is this the S70 that will get the ECU I sold you a little while ago ?

The ECU that's in the car now has a tune that "might" be OK for what I have planned. If not, then I'll use the one I got from you and get a custom tune

Good stuff. I know TME's (what IPD carries) isn't custom but from experience (ST USA, RICA, TME), TME's tune was head and shoulder above the rest with my set up.

Head is on and torqued. Just haven't had time to do much lately ....

Oh yeah, so no one busts my balls, when I'm not working on it....

Looks nice. I wish I was able to get my block the clean before it went into my car.

I'm doing a lot of research for a winter project and came across your thread, it's extremely informative and I'm looking forward to future updates.
I do have a couple quick questions.

1) When you had the block at the machinist, did you have the cylinders bored at all? Will you end up at stock displacement or larger? I did notice your CR rise but don't know if this will change the total displacement. Is there any advantage to increasing the displacement? Other than the obvious bigger motor, but will it adversely affect the durability of the block?
2) At the beginning you mentioned the con rod and pistons coming from a dealer, you mentioned they were RSI rods, were these from a Volvo dealer? Any particular reason you choose them?
3) Don't recall seeing, manual or Auto trans? Unless this is for the '98 S70 T5M in your sig, in which case never mind.
4) Any ballpark idea of final HP?

Thanks and I know a lot of people are watching and learning from your thread.

I have heard that ALU blocks typically don't need media blasting. Cast iron on the other hand :-/ My 4 cyl block is being media blasted as it is cast.

[YellowT5-r]

Very glad to hear you got most of your rotating assembly balanced! Some white blocks can have nuts bad balance from the factory (my crank was over 50 grams out of balance at both ends!

Also, don't worry about bumping your static compression a bit. On my '01 LPT motor that started life at 9:1, we had to machine machine off upwards of 50 thou between the deck and head to get them square again and have had no problems making some power running 17-18 pounds of boost. Off boost throttle response is fantastic though!

Yeah, looking back I probably should have just used the original pistons. I'm sure the car would be a little quicker out of the hole with a tad higher compression. Oh well, live and learn....

RSI rods are from R-Sport International--->RSI

Sorry I took a couple of days to respond. I must have missed your post

1) I only had the cylinders honed since they weren't worn excessively. Since the engine I'm using is a 2.4 (83mm bore) the cylinder walls aren't as thick as the 2.3 (81mm bore). So I was happy it didn't need to be bored.

2) As rkdlittle mentioned the h-beam rods are from RSI. The pistons are OE Volvo. Big reason I chose them is our shop has a wholesale account and the price was right. I think they will be fine for my modest HP goals.

3) Yeah this is going in the '98 T5M.

4) The engine build cost a little more than I had planned, so right now there's not enough left to get a BIG turbo. So I'm gonna see how much HP I can squeeze from a K24 with all the normal bolt-ons. As far as HP.... who knows?? Anyone have any idea???

would this be the appropriate time to say i told you so?

jk jk

higher compression with boost is the most wonderful thing in the world =]

looking good man as for horsepower with the k24, it really depends on how much you want to squeeze out of the turbo, but i think it should make more than you want without an LSD i would think 350whp is a good number to stop at with it...

[s_moneh]

can you actually put down 350whp without an LSD? because if you can, the quaife GB failed and i'm more then willing to move on without it but if not i can wait and do LSD my next clutch job

The most you will see out of a K24 is maybe 330whp.

Yes, of course you can. Will it survive hard launches, prob not.
