Ok here I go. I was driving out to my buddys place giving my car a bit of **** (240 kph) when it lost a little bit of compression.. make a new exhaust manifold of the Tial 44mm wastegate and shortly after it went pop. I havent cracked it open to see the damage yet but what can i expect?

Engine was an extend port but want to go bridgeport or just a drillport for the nice pulse but wanting to know what this will do for my reliability.. car will be prefessionly tuned again..

Mods so far:

Turbo

series 5 exhaust housing with garrett t04 front cover, 44mm Tial wastegate

GTR Front mount

500hp fuel pump 660cc secondary injectors

Microtech lt-8 ECU

Hks hyper damper coilovers

thats all the basics i think. Anything help would be great thanks guys.

 

You don't need a bridge port.

 

I know i dont need a bridgeport but I would like one

 

Bridge = Brap = WIN!

Seriously though a well done regular bridge shouldn't affect reliability but the increase power output might. A bridge port will also affect timing (read drivability).

 

the porting will be done by a guy been building rotories for 30 years who now works from home and tuning on a dyno by one of the best in the country who also builds rotories.. i realise the idle will be higher too

 

More than the idle, the power band will be higher too.

 

Threads like this hurt my brain for several reasons...

Reason the first: Stock hybrid turbo. The hot side is way too small, especially for a bridgeport.

Reason the 2nd: People randomly saying things like "you don't need a bridgeport" without asking the original poster what his power goals are

Reason the 3rd: Even suggesting the use of a "drillport" should be an instant ban.

Reason the 4th: The setup quoted does not have enough fuel for an upgraded stock turbo, let alone something that has been turned into a hybrid

At any rate, unless you plan on making upwards of 400HP to the wheels, most would argue that a bridgeport is not necessary at all. The tradeoff in fuel mileage (8-10 MPG in the city) and tuning difficulty is not worth it.

You need larger secondary injectors. If you do decide to go with a bridgeport, you will need a full turbo upgrade with a much larger hot side and of course all the other mods to go with it.

 

i dont mind getting a bigger turbo for it as i may as well go a bit nuts on it and was planning on getting some 1680cc injectors.. surely this could support it?
I don't want to run insane boost just want enough to put a smile on my face when I step on the loud pedal

 

wtf is a drill port?

 

Think about a bridge port. But instead of a long slot it is a series of drilled out holes instead. Its the Ghetto bridge port.

+1

 

Wouldn't this type of port be more for the BRAP sound and less for power? As in "poser port" ?

 

I've always assumed this was the way to do a bridge, drill then grind.

 

1680CCs will support mid-400s just fine. A simple street port and moderately sized turbo will put a smile on your face. Standard 60-1 setup, or go fancy with the GT35R. 400HP all day, no need for crappy fuel mileage around town.

Bingo.

That's how it's done. The difference is that the "drillport" or "cheese port" does not grind out the space between the holes. So the only thing accomplished is intake dilution.

 

dont really care about crappy mileage as its a weekend car but thinking of saving my money now just a basic rebuild and save for something else
