38mm is fine...that should be on the flange on the kit i sold you...40-50mm is fine on the bov...you can get them cheap from vs racing on turbomustangs...just the x02 brand you dont need high dollar stuff

Hello,
Wastegate is after the turbo. It diverts the air from the pressure side to the exhaust for overboost conditions such as limiting boost and between shifts among a couple others.
Damon
The wastegate needs to go before the turbo! It diverts exhaust gas away from the turbine to prevent overboosting during engine acceleration.
I believe Damon meant to say a "blow off valve or BOV" (not a wastegate) goes in the charge pipe to limit compressor surge when closing the throttle blades as can occur during shifts.
Here's a pic of a wastegate flange location on an import engine. Same concept on your car, somewhere before the turbine side of the turbo.

I was alittle confused there. I knew the bov was after the turbo. Should the BOV be close to the carb/throtle body or anywhere after the intercooler Thanks

The wastegate is before the turbo, and likes to be oriented in a manner that the exhaust can run right into the gate on its way to the...see the picture for explanation
The bov can go just before the carb/throttle body and is always closed and uses vacuum to open it
a lot of guys put the bov before the intercooler, others do it after, myself there is no intercooler to worry about yet

Why do people comment when they have no clue what they are talking about gets me for sure....
Wastegate is before the turbo and as close as you can get it to the turbo or merge area, it vents exhaust way from the turbo to get the boost you desire....BOV is before the carb or injection. i dont think it really matters if its before or after the intercooler, mine is after, close to the carb, and you should always have one. It prevents compressor surge which will damage a turbo. i have X02 wastegate (60mm)and Bov(50mm) and have less than 250 invested for both of them and they work awesome, they are HKS knockoffs and would recomment with any cheap knockoff to take it apart and clean lube it well. i got both of them from Vsracing.net a site sponsor on turbomustangs.com

Like dodge turbo said after the merge before the turbo. Mine is about 3" from the turbo just make sure you vent both sides of the engine not just one.

That will work. It will also be most annoying. See the trumpets? They'll hoot and holler every time you let off the throttle. Ricers flock to them. It's like a fart pipe muffler for the intake. Find one without a trumpet and it'll be much easier to live with.
Factory turbo cars usually route the BOV back into the air filter to silence them.
On the wastegate, think of it as a short cut. When boost gets too high they open up and let exhaust sneak around the turbo and straight into the exhaust pipe. Again, smoother is better on the plumbing.

yes i sent you that spacer when i sold that too you....and that is the wastegate...the bov is by the carb..
that was set up ran 7psi fine all the time with no creep at all and a masterpower 70mm turbo and that 38mm wastegate...
That H1E i sold you will fit right on there and is t-4 flanged and is about 67mm in size if a rember

thats a 38mm wastegate flange for a 38mm wastegate...you can plumb it into the down pipe or cut a small hole in the inner fender well or route a pipe off it to underneath the fender well and vent it

Can be as close as you want. Some turbos have their own internal wastegate built into the exhaust housing side of the turbo.

Hello,
Yea, I stated it incorrectly. Sorry! Was in a big hurry. What is up your back side Josh? Thanks for the personal attack.
Damon
It was a response to the info you typed, not you personally. When you accidentally type incorrect info it can lead someone astray.
However, 'trust but verify' is ultimately the responsibility of the car builder. This is why I'd recommend to any newbie to buy a few books and learn the basics on their own. $75 on 3-4 books is a cheap but wise investment.

Well I listed my stuff forsale as I dont believe Ill have the time to build a turbo truck and had to sell a couple trucks to downsize and save some money. Plus I dont think I could figure out how to set up the timing, ign or if I should carb or efi and from what Ive seen you guys have for a fuel system I really cant afford that but If I dont atleast get what I have in the parts Ill just hold on to it. I have the H1E Turbo, the turbo manifold the wg Flange an intercooler, down pipe and a crossover pipe to conect both manifolds. What else would I need to finish? Waste Gate, BOV, Carb or EFI, piping What would be best carb or EFI and what for the fuel system and how to make it retard or advance when needed? I really dont want to get rid of this stuff but I can find another truck cheap as I'd rather have the truck look beat for the ultimate sleeper. Any thoughts and encouragement

Thanks. My main thing is I dont understand the whole ign thing when boosted.
'Ign when boosted' is somewhat simple. Generally you want to reduce timing when under boost, usually a few degrees per lb of boost. Look up the MSD BTM (boost timing master) for more info.
You can probably find better explanations out there, but the overview: The burning of gasoline in a cylinder is actually a controlled burn, not an explosion as we would normally think of. Detonation is an uncontrolled 2nd explosion in the cylinder, after the spark and from the other side of the cylinder, and the collision of the 2 flame fronts cause incredible cylinder pressure near TDC. Detonation is a killer of boosted engines. Hot temps, lean mixtures, hotspots, etc, can lead to detonation. Denser mixtures require less ign advance because the flame front jumps across the fuel particles faster and in a controlled manner (ideally, anyway). Lean mixtures have further to jump, and require more time for it, so they need more advance.
So, in a boosted engine, you have a nice dense mixture in a cylinder that is surely hotter than it was as NA, so you reduce the advance because you don't need it and you don't want it.

Its funny that when I first got this setup everyone wanted the manifold but nobody has contacted me on it. Not a big deal to me.
I saw a smallblock turbo manifold in teh Swap section recently for $350 IIRC. If that one's yours, the price may have doused people's interest in it. Although there aren't a lot of those manifolds out there and market price is hard to establish, $350 might make guys look for cheaper options. Just IMHO.
