Down the rabbit hole -- 2276 MS3X Turbo build

[theDrew]

Thought I'd start my very own build thread cause I'm that excited about it.

This is my first adventure with a turbo -- advice is always welcomed.

I've been planning this for a while, its exciting to see it starting to come together.

I'm trying to size everything so I can eventually use it with E85.


I'll try and keep things updated as I work on it.

Build Specs:

-AS41 mag case, std bore & thrust
-AA 4340 crank
-5.400 h beams w/ ARP2000 bolts
-ACN Squishies
-Web Cams 86b
-Steve Tims' Stage 2 heads, 59cc chambers
-Udo tool steel lifters
-8740 8mm head studs
-total seal gapless 2nd rings


-T3/T4 turbo from Shag, .48 ar
-TiAL 38mm wastegate
-Turbosmart Vee Port PRO blow off valve
-CB's hideaway header

-FiveO motor sports black ops 1000cc injectors
-CB's high flow injected manifolds (matched by Steve Tims & Co)
-intake and intercooler still to be worked out
-single throttle body -- prolly 50mm.

-MS3X ecu
-LS2 coils
-Mario's cam sync
-a whole grip of sensors


Here my 74 super

my case back from the parts washer:

measuring main bearings
main bearing clearances are .0020 - 0.0025

after everything is back from being balanced, cleaning and assembling

cleaning cylinders over and over and over

Mocking things up and setting my DH.

With my heads being 59cc, I have to run a bit bigger DH than I'd like.

With the squishes having the 4.3cc hump on it, it makes things a bit interesting, my deck height tool is cut up to accomidate it.

After consulting John @ ACN, I'm shooting for a .070 dh, which puts my static compression at 9.4:1

I hope john doesn't consider the picture part of the NDA. Although it's obscured by the plate and dial. You may want to remove it asap.

Does he still bother? I didnt get one or sign anything with mine. Not saying its alright either.

[UK Luke 72]

Following this
What exactly is under the NDA? Just the outline? the angle of the hump? The CCs are widely known, I don't see what he can actually do other than legally protect the name (super-squish)... If EMPI started leaving a dome on the piston that was kind a around 4.3cc and kinda sloped toward the ex side of the chamber not saying it'd be as good as johns but...

Onto bearing clearances is that measure with the bore gauge or Plastigauge?
How come you aren't going for a turbo specific cam grind?

[theDrew]

[theDrew]

few more measurements i'll add:

using total seal gapless 2nd rings

using their guidance, gaped the rings to 0.021
(up to 15lbs = 3.70079in x 0.0055 = 0.0203”)

rod side play was 0.010 - 0.011

Good luck!

I will be watching this, as I am working on a 2232 efi turbo build. Undecided on a header and turbo at this point. Having SL prep a turbo and making the header myself is most likely at this point.
Are those the "thick" 94 cylinders?

Got the block together last night. I'd put it together and taken it apart so many times its nice to finally declare it done.

some highlights:
CB's max-flow pickup

went over the all the edges on the cam with a smooth file

udo becker tool steel lifters

CB's pro series straight cut cam gear, running straight up

last look at the internals

get yourself one of these....makes life much easier

and p&c's in, i clocked all the rings according to total seals guidance

Drew,

Love the build! Definitely will be following.

Two quick questions, Did the heads have to be setup
any differently for a turbo build?

I thought I read somewhere that turbos will eat up the
valve guides or something about how heads need to be
setup for turbos (of course lower compression/larger chambers)
but did not know if anything else had to be changed..

Also how was your last build performance wise?
I am looking to run something very very similar and
want to understand how yours ran before..

Thanks!

I like to put the oil pump in before torqing, just me. Did you check those cam gears for run out and lash? Mine were so far off it wasn't funny. Like your hidden trigger.

[theDrew]

i checked the cam end play a while back, it was spec, I can't remember what it was.

i couldn't feel any lash, but I didn't actually measure it.

my old AA straight gear set had lash I could feel, so I took this as improvement

no work last night, but here's some of the goodies i'm stoked about

turbo by shag. .48 AR, shag's recommendation since I wont be going over 7k rpm (or for long)

close up of the trigger wheel (from Mario @ dubshop). Some advice, pay him to do the machining. I had to go back to my machine shop 2x to get it just right. CB's serp belt setup.

TiAL 38mm wastegate. 7 psi spring in it. I have a boost controller for the MS3 when I'm ready to go higher. I'm a sucker for shiny colored anodized parts

Nice build thread. Thanks for this. Though I'll never build something like this, it's interesting to follow along.

Is this beast gonna be ready for the NW Bug Run? I hope so. I'd really like to have a look at your engine.

Keep posting updates.

Good Luck.
