Generic 2.7i build for boost in progress

[TobyB]

I don't cut the decks, either, unless there's a good reason to. Clean and straight is
clean and straight, and I've never had a problem... and a cut deck adds another
variable into the already not- trivial cc equation, especially when you're targetting a
particular cc and sending parts off for work based on this...

I do spend money on
pistons, maybe because I'm a fool,
maybe because the M10 seems to always eat them.

If they measured ok, they should be fine.

One of these lifetimes, I really wanna do this.

Well I am trying to keep it reasonably cheap hence the used Pistons, they were in really good shape apart from the number 1 ding. Ring lands measured out in spec. I guess I'm willing to gamble on them.

I asked the shop about the deck and he said he'd check it for flatness and machine if needed. He said it was perfect and not to mess with it. That plus the o rings have me pretty confident in the HG seal. Have you seen many warped deck surfaces on these motors?

[digger]

and why not a freshly machined block for better HG seal?

[TobyB]

You're going this far- why not new pistons?

Small progress today, still waiting on the head so I can't do any of the fun stuff yet.

Anyway I practiced a whole bunch of aluminum tig trying to get myself up to a level where I can weld up my intercooler piping. After a bunch of frustration I think I'm getting the hang of it. It's not pretty but it'll work.

Some of my practice:





First actual pipe that's going on the car



I don't have a bead roller for the end so I improvised by laying a hideous weld down instead





Also got the freeze plugs installed. I used "the right stuff" to seal them.





And got my turbo oil feed/oil pressure gauge stuff figured out.

It's an M12x1.5 to -4an converter attached to a special fitting made to install a fuel pressure gauge but it so happens to be perfect for this. It's got -4an connections on each side with a hole tapped to 1/8npt in the side.





That's it for now. Head should be here this week so the fun should begin shortly.

[Steve o 77]

small victory today, got the stainless wire laid in the block, what a PITA that was.







Also got some artsy fartsy pics off my DSLR



















Also picked up my long time dream tool, a TIG welder. So excited to put it to use on the exhaust and intercooler piping.

Yeah good n tight manifold.

Wasted spark is pretty simple, you need to make some minor mods to the megasquirt then go to the pick n pull and find any pile of garbage gm v6 car and get the coil pack module (the thing the coils bolt to). I got mine from some POS Pontiac with the 3800 v6. Then you just rip out all the electronics and wire it up like my picture.

I got the same manifold hold up my hx35 is that a good n tight manifold .., I build my ms myself and running car and rotor for now .., wanna go wasted spark soon too ., just need to solder a few drivers on the ms board

[88BlackS-ETA]

Damn, nice going. That manifold looks good. Im doing a turbo setup with a HX35W and it will only have a head build but the bottom end is also from a 2.7L SETA and that will be stock. I'll be using a billet 272 cam, hd rockers, stainless steel valves and new OEM double valve springs.

Anyone know what all is involved for wasted spark? Im thinking of running stock cap and rotor and coil.

[Steve o 77]

Uhm.... what's all that white stuff on your wasted spark module? Lol, build looks sweet man.

I LOVE wasted spark, get off me bro. Lol

No it's some rtv stuff I found at work, figured it might help prevent corrosion under the cover.

So I just got this in the mail from a fellow member.






Also just ordered a MSPNP from kamotors that'll be pre wired for wasted spark and have a tune that should get the car started.

[Steve o 77]

Me either. I'm getting all antsy waiting for parts. Definitely want it running for the start of auto x season which I think is doable.

[Tonybeemer]

Very interested I'll be doing the same exact setup soon .. But with a hx35 .. Can't wait to see how this monster comes out

[Steve o 77]

Got the rotating assembly all wrapped up. All the bearings measured .0018"ish.

Ring compressor was a PITA but it works.









Now the waiting game. Head should hopefully get here within a couple weeks.
