I'm going to buy a j-bridge ported 88' turbo2 motor and I was wondering how different it is from a stock motor. i.e. -- what is the low-end torque like? whats the horsepower on the motor? how reliable is the motor? what electronics/guages do I need to make it reliable? thanks in advance, Jordan

email me PenguinCrisis@aol.com if you can help

j-bridge doesn't last too long because there is no water seal near the intake port, and it will leak coolant after a (short) while

That J-bridge won't last as long as a streetport engine, and when it fails it's going to take the entire engine out with it.

A J-bridge is not supposed to be streetable...

any motor is streetable it depends how crazy you are!!
The are many different types a j-ports most of the can be done without going into the water jackets only the real extreme j,s go into the water jackets.

If it doesn't go into the water jacket then it's not a J-port! That's what the J means - jacket!

A BP lasts longer than a J-port. I would take a BP if I were you.

A BP lasts appx. 3000 kilometers. Not very streetable unless you happen to have a lot of rotor housings laying around.(I've only got rotor housings laying around).

Stick with a good size street/exhaust port.

WAY more dependable(Years instead of Months) and will give you more horsepower without sacrificing dependability.

Please tell me that was a typo and you didn't actually say 3000km? I'm not sure about turbo applications but a typical n/a bridge-port will last way longer than that.

What would be the cause of such a short life on a turbo engine?

Soul assassin's engine died after only 3000km... lost a seal... not really indicative of how long a BP could last.

For that matter I could say that my street port engine died after 37,000km, therefore all street ports will last only that long. Or the stockport in my '87 died after 125,000km, therefore all N/A stockports will last that long.

It just don't work that way....

from what i hear, j-ports were realized when racing leagues put bans on peripheral port engines. the J-port is meant to flow like a p-port but still remain in a somewhat stock configuration (side intake). a bridge or p-port even will outlast a j-port with no problem. The main problem with a bridge port or a p-port is NOT the porting of the engine, it's more to do with the engien being able to breathe at higher rpms and therefore make more hp. Anyways, this higher rpm will kill your engine faster (duh). Stick to a bridge port though, that's rough enough. P-port/j-port runs smooth for acceleration, but at idle it sounds lumpy and it's drivability has been compared to a "bucking kangaroo" by some aussies (damn, those aussies and their rotary 'skillz' )

The funny thing is, in the US, anything that extends into the rotor housing is classified as a peripheral port - this includes relieved bridge ports, since the rotor housing is partially cut away. Since a Monster and a peripheral are classified the same, might as well just go peripheral...
