i kinda knew it as soon as i realized i blew the motor. I starved it of oil.

I pull over and inspect the motor, go to check the oil and the dipstick is almost dry. ya a REAL stupid reason to blow a motor....



93 BLACK FD- how did you motor blow like this? did you starve it oil as well or was it from somthing else.



My plans are to get a haltech( done with piggy backs) full t4, and brigdeport. As of right now im going with S5 irons, still dunno which though, NA or T2, and S5 high comp Rotors.



My mods are listed under my sig
That sucks. I did that once 5 years ago in Decembre 1998 when I left my oil filter off my car. It happens to the best of us.



Let me do your bridgeporting and your motor; I can help you with the Haltech setup as well and getting a map done for the motor. It's right up my alley.

my advice if it counts,stay away from the bridgeport,unless you have a major engine budget.life is generally shorter on a bridge.as far as making power a well know steet port works very well.(its the turbo that makes the power)

well with dumping all the money he already has in his car i don't think he's worried about the engine life (with the right setup bridges will be perfectly reliable)...and turbos do make power, but ports are what make them flow efficiently....

When speaking of bridgeports that leave either extremely little metal for the corner seal and apex seal edge(s) to ride on *or* bridgeport cuts that protrude into the inner water jacket o-ring land, or further, then you've got reliability issues. Otherwise, there's nothing wrong reliability wise building one that has bridgeports that are more conservatively done w/o major interruption to other components.



Very conservative





Slightly more radical yet still unobtrusive and reliable

i would really want to see the dyyno chart with exact same portign minus teh bridge and all the same turbo hardware and all same boost. i just dont think its realyl worth bridgeporting unless u really do a large bridgeport. i tend to belive that when bridgeportign your main goal is to make that bridgeport the main concern of flow or atleast givign it great attention of the way teh air will flow.

i think goign all the way in up to teh water seal and nothing the rotor housing is the best for the flow without really affecting the reliability. but leaveng the bridge itself somewhat thick and not put so much overlap on the original (streetport) part of the port.

Well I guess it isn't all bad, won't cost you as much as you were expecting.

actually no, i didn't starve it of oil, oil cooling, or oil flow, i had the motor optimized for maximum oiling effeciency (dual coolers, -10 lines, stage 3 oil mods from pineapple, etc)



it just failed....and pineapple concluded it wasn't their fault



sucks eh? at least you know what killed your motor

Perhaps debris left in the motor from all of the machining work ,etc. that was done prior to engine assembly ....

I would tend to agree but I believe that this rule is susceptible to the goal and power output of the car, the purpose of it, etc. From what I've noticed, on turbocharged cars, is the smaller bridgeports as additions to the main extend port lend for higher peak horsepower and torque at high RPM as well as "stretching" the powerband out further all the while not heavily reducing low-end streetability, take-offs, etc. to still keep the car moderately comfortable to drive.
