i'll be there one way or another, I'm not sure it will be done by then, but deadlines make the world go round!

Looking good Drew!
I will be watching this build up. I have been contemplating a turbo with the CB high flow end castings for my spare 2176cc. I look forward to seeing what you do for an intercooler! |

me too! Trying to shoe horn it all under the decklid will be interesting. I'll be using a water to air intercooler -- I need to get it in the engine bay to start mocking up how and where everything will go.
using the high flow castings will get me some extra space, that's why I decided to go that route. also, ITB's are such a pain to keep in sync. even with the SyncLink (which works fantastic), I was always fiddling with it in search of perfection. IMHO no matter what, one will follow the other.

I agree with you on the simplicity of the single TB versus ITB's. Not sure how the performance difference would be between the two once you apply boost though.
Since you are going the single throttle body route, you should look at how Shag did his intercooler. Mounts behind the shroud on the drivers side and makes the piping look pretty simple. I am sure there are some complexities to it, but keeps the engine bay super clean. Or are you thinking more along the lines of a barrel intercooler?
Well I am glad you are doing the ground work. Based on how yours does, will determine my plan of attack in the next year or so. |

These are good for up to 350 hp..nice compact size.
Also look at the mustang/escort throttle body. It has a good tps and has a very easy to setup idle valve. You can also find BBK for ford (bling).

A 45mm to 50mm Single TB would probably handle whatever you would want and give you drivabilty too.
A stock German Beetle TB is 45mm and that is what I am running on my turbo.

did I mention I love anodized red? also have his red pushrod tubes as well.
heres my injectors -- flow matched and tested by FiveOh motorsports.
1000cc/min Black Ops injectors.
DIY auto tunes boost controller:
managed to get out in the garage and go over the valve train a bit. the swipe is looking good, so I dont need to futz with it.

Why are those spring retainers smaller in diameter than the springs?????

i trust Steve & Greg Tims expertise. I haven't changed anything on them.

awesome build, cant wait to see the finished product. I might have to track you down at a show and ask for a ride 
curious though, are your head studs different lengths?
are you hoping for reduced knock and/or detonation by running squishies with that compression ratio?

ha, good eye -- I'm using some SCAT 8740 studs which are 1/2" longer than stock. I only cut down the ones that interfered with the rocker assembly.
yes, the squishies let you run higher CR on boost. I believe Chip B was pushing 20lbs on pump gas, and like 28lbs on E85 and his static CR was like 9.2.

| You're sure gonna have a whole lot of fun when done. Your build is on point. Some advice I do have is to build up the fuel system to support those injectors to their max so you dont have to go back and redo again when on E85 you find that more than 300hp sounds like fun. I don't know if youve ever tuned F.I. before but once thru the newness/learning curve the ability to add more and moore boost/power and control it with the ecu is exciting like the feeling of going from a1600 to a built 2ltr for the first time. I'll be looking forward to your updates. |

My highest 91 octane pump gas number was just over 24psi, without water/meth. I'm a believer  |

| So do you have your heads cut to fit the piston crown? Is there a one stop for buying the pistons and having your heads cut to utilize them? What about running e85 with this set up and an even higher static CR? I ask because I am working on putting together a 2276 for my 65 plan is high CR (12:1) naturally aspirated efi and possibly turbo it later on. |

I recommend building it one way or the other. With big chambered heads, there is not a lot of clearancing required. I have had to do minor chamber manipulation in the past. All of my heads have had chambers in the 60+cc range. Small chamber heads are where the clearance horror stories come from. |

It would seem that this set up along with e85 would provide a large gain in power not to mention the cooling effects from both also with e85 you should be able to raise cylinder pressure even higher am I tracking here? |

correct, and e85 has a higher octane rating.
so downside is your fuel system has to handle almost 25% more flow, but if planned correctly and with a flex fuel sensor you can adjust for it all in real time.

I switch between e85 and gas regularly. I have a sensor. Works great. |

Little more work tonight...got the pushrod tubes on and pushrods and rockers on.
Jaycee red (of course) push rod tubes, ACN's Heavy Duty Ally PR's and some lash caps. (I know the debate on these, I like em, but I know some dont)
I took a set of Scat SS valve covers and welded on some AN-8 breather ports on the 1-2 side. two of em, cuase why not.
Speaking of AN fittings, here's my stash of AN-6 for fuel, AN-8 for oil and breather hoses, AN-10 for the turbo drain, and AN-4 for the turbo feed -- been buying em a couple at a time for months.
I got a Setrab 1x19row oil cooler to add to the million things that will be going on in the engine bay.
And a Mocal thermostatic sandwich plate to hook it in to the oil system
