wat accilaries do u need 2 run a bridge port is it much more than a large street port. im going single turbo

yes it is larger than a streetport, but it is called a bridgeport as a bridge of metal between the main port and a smaller port. I am still running stock ancillaries currently, power won\'t be massively improved until the big turbo and decent cooling (FMIC, V-mount) are done, but a decent bridge will be able to generate more power when combined with a big turbo than a streetport will. Idle will be more lumpy, but it is still road useable.

i think im turning to the bridge port side of things hav u had any problems will twin egnition coils help and a better fuel pump, fuel regulator and injectors also water injection

Depends how effecient the ports are.
A bridge done properly will give you more power than a street port full stop.
It will generally spool the turbo up quicker too.
If a street port is done right it can be almost as effective as a bridgeport but not quite.
If your car goes to someone who knows what they are doing then you really don\'t need a bridge to extract loads of power.

best bet is a 1/2 bridge (i.e. the secondaries are bridgeported, the primaries can either be standard, streetported or in a full bridge, bridgeported). Uprated fueling would be necessary with your planned mods either way. I have uprated my coils and ignitors (although this isn\'t necessary, but I have an FC I believe that the FC\'s ignitors/coil packs are stronger than the FD) you\'ll need to uprate your injectors, pump and fuel regulator.

is there a kit they do for a bidge port engine eg coil pack injectors fuel pump

not sure, I can certainly get all of the above, but not in a kit.

do u no who sells these items any websites with prices

sadgoth · August 05, 2005, 04:34:30 PM

not off the top of my head, drop me an email (mark@japspy.co.uk) and I\'ll have a dig around and see what I can come up with in terms of contacts and mail u or call u back

Just to expand on a point slightly earlier on, there are two intake ports on each chamber as it were, primary and secondary. You can run different ports on the primaries and secondaries if you wish, or for monster power your best bet is to go for bridge ports on both primaries and secondaries.

However, bridge ported engines, especially those on primaries and secondaries, will give you a rough idle and make it uncomfortable in traffic. The plus side is that you\'ll get more power from a bridge...
