hey i just got a half bridge put onto my s5 TII and want to know is it safe to run on the stock setup i do have a fcon and super AFR do i need bigger injectors? i do have the walbro pump also thanks Corbit

are u gonan run this on a stock ecu? i woudl recommend you get a haltech or a microtech. the stock computer is realyl nto meant to run what you have in there.
|
The stock computer most likely will not run it anyways. When go BP you need to upgrade everything...
|
ya i am going to try and run it on the stock ecu with my piggybacks. The guy who did my bridge is running his on the stock ecu but his is n/a
|
its kinda of a big diffrence runnign a bridge NA on teh stock ecu then a turbo. i assume you are not useing the stock turbo on you rbridge turbo?

Would'nt that bridge snap under all the pressure put out by the turbo?? You rarely see bp turbo setups because of them supposedly snapping. I heard it somewhere.

They run fine, Rowearth. I've been doing these setups for just over a year now and have almost 15 of them out and about. The trick is to leave the seal bridge thick enough to withstand both seal spring pressure and heat cycling.
I don't think there's any way in the world a half-BP engine will run with the stock ECU. None whatsoever. I set my vehicles up using Haltech EFI systems and they take quite a bit of trickery and map changing to get them even in the ballpark. B |
sorry to hyjack this thread but ......so u can run your stock computer if u have a bridged n/a or ported in any way n/a?
|
Why spend all that money a BP motor and use the stock ecu and blow it up? You will need to get a aftermarket ecu, then get it tuned. There is also no point of running a stock or small turbo with a BP, you will only overboost the capabilities of the turbo. Don't forget fuel, stock will not be go enough.
Do it right the first time!!! |
exactly, if doing a bridgeport you shoudl upgrade all that is associated with a doing it properly otherwise the geans are nto gonan be that great plus u are in danger of hurtign the motor. if you took the time and money to do the bridge then do the rest. this is also why i dont like bridges and think most people should stick to streetporting. the costs of doing a proper bridge are much greater then what peopele think of it. a standalone should be a must anyway on pretty much any rx7 you get now, most rx7 i come across have a SHOT wire harness and the ecu doesnt work as it did back 10 years ago either, this includes the FDs also. so a standalone should be on your priority list anyway, even on a stock car you can get more power without any mods.

oh i agree with what you all are saying, i do need to go stand alone. The thing is i did a street port on it and took it into a shop , to have someone check out my work ,the guy said i did a good job but that he would hook me up .He said he would clean up my ruff spots and then put a little half bridge on it. This guy has bein porting rotory motors for 7 years. This bridge looks nothing like any other one i've seen. It is very short and wide when I asked why it looked like that he said because of over lap in timing so he made it short. I really dont know enough about over lap and timing to say. But he did a really nice job on it, looks outstanding. I do plan to upgrade injectors ,at least 720. But this guy tells me he is running the stock set up( ECU ) on his ride and doing great. I really dont want to blow my motor up after doing a rebuild. When i get it back i will take some pics of the port to show thanks for all your input
