3500 Turbo Material

[Weatheralls Auto]

I have a few ???
Gathering and planning what I will need for this winters build.
So far have the Turbo
the 1.5" (1.65"ID/1.89"OD) Elbows and Tees for the Log Manifolds.

?#

1. What size of pipe should I use for crossover? and should I use the same said pipe to the Turbo itself?
2. Planning on going 3" Exhaust from Turbo, but space limited, would using 3' of 2.5" be much of a detriment?
3. Using the TCE 65mm TB and was planning to go 3" Intake, however, the best Intercooler I have found is only 2.5", will this be too much of a restriction? should I just go 2.5" throughout till the TB?
4. What size Blowoff valve will I need? and what size wastegate?

Hopefully they are 4 simple questions lol.

1.No bigger than 2" pipe for the crossover. You want to keep exhaust gas velocity up before the turbo. Don't forget only exhaust gas from 3 cylinders will be flowing through each side of the crossover. This is an area where alot of guys make a big mistake - thinking that bigger is better.

2. Try your best to go 3" right from the turbo all the way back. On this side of the turbo, there is no such thing as too big. You want lots of room to get those exhaust gasses away from the turbo as quickly as possible.

3. 2.5" piping for the intake is more then big enough. In the words of Corky Bell " when you have a choice between 2 sizes of intake tract piping - choose the smaller size". Again this is another area where bigger is assumed to be better. However, it will just introduce lag into the system, since you have to "fill" that 3" pipe with pressure before the engine sees anything. Also, 2.5" = 63.5mm.

4. a 40mm BOV and 38mm wastgate is more then large enough. Large wastegates are required for large cubed engines that are running relatively low boost.

Incase you are not aware, I currently have a 3500 Turbo 5 speed Beretta, which I've run a best of 12.52 @ 119MPH spinng the tires like crazy. The above suggestions are based on A LOT of research done on my part before I tackled my project.

BTW - I'm In hamilton.. so if you need a hand with anything let me know..

Oh I do know! lol
There were a few members I was homing would reply, and you were ONE of them.
Thanx a Ton!

BTW, you have pics of your setup? I looked at your profile but none there.
Yours will be much different than mine but it may help with Ideas, trying to figure out the best position for the Turbo itself.
Of course mine is a Tird Gen Cavalier, but more Ideas the Better.
Few issues I will have,

1. Which way to position the Turbo. It will be in place of the Battery, My Air Intake is from the Ram Air in hood, so just to the drivers side of the Master Cylinder.
   Then I am wanting to run from the Turbo, between Engine and Rad Shroud at the top.
   Down to IC from Passenger side back to drivers side to the TB
2. Routing the Exhaust back out behind engine. Limited space and don't want to get rid of the ABS to make more room.
