Well, here it is. My 93 fd is currently at PFS to have a single turbo convertion, street port and meth injection kit. Now, after someone put a bug in my ear that I should go with a full bridgeport( thanks Ernie, I'm blaming you if my wife finds out how much this will cost... lol) , I would like some feedback from others who have had the same done. Are there pros and cons I should be aware of?

 

Your car is at PFS and Ray Wilson did not even recommend what you should do? This seems strange. What are your goals for the car? Seems to be just....a street car to me? But I could be wrong.

 

I never said Ray didn't give any recommendations. I was just looking for some additional feedback from others that have had their motors either streeported or bridgeported. And right now it is just a street car, but isn't that how they all start out? My goal is to get it to the point where I can take it to the track and have it perform to it's full potential. Now that I've explained my situation and intent, do you have any input?

 

Full potential and still be streetable? or just flat out full potential where you have to trailer it everywhere?

 

Still streetable. This is by no means a daily driver, but I don't want the hassle of towing it.

 

Streetport.

 

Why?

 

Your new here, first lesson listen to Aaron Cake!

 

Sorry dude, no offense, but I need a little more than "listen to this guy". I'm looking for reasons. Like will I end up with a stronger more reliable build with a broader powerband. Will the engine last as long one way more than the other. I'm spending an *** load of money right now and I'm just trying to spend it in an educated manner. So forgive me if "just because" does not suffice. Once again no disrespect intended.

 

full bridge wont last no where near as long. street port will give you a good power gain still remaining realible. alot of things need to be done to do a full bridge some small some larger. its alot more costly do a street port and you will be very happy. years down the road when (if) u get bored of that think and research a full bridgy

 

heres some info

It really depends on your goals.

since you want a street driven car, a bridgeport is way over the top, you lose reliability, fuel economy, low end torque and your power is all going to be top end power, ie over 6k rpm, which means your going to spend a lot of time at high rpm and on the street thats not so good.

a streetport can make a good 500 or more whp without sacrificing so much, and it will still be streetable.

my opinion? streetport.

 

Thanks guys, and like I said, I do intend to spend a good deal of time at the track (since I can't afford the tickets, but can't keep my foot off the gas). Anyone else like to chime in?

 

It depends on your goals really. But if you are planning on less then 500HP, the streetport is far easier to tune then the bridgeport. The only disadvantage is that as you start to run a larger turbo, they will get laggy without a bridge to spool them. Also the streetport will get far better mileage on the street.

A properly done bridgeport will be no less reliable then a street port. You get into reliability issues when the bridges are cut razor thin or the eyebrow intrudes upon seal paths.

 

iam talking about FULL bridge. so yeah less realiable.

 

go with a half-bridge.

 

3 rotor......

i make useless posts........

 

I also understand that a bridgeport reduces vacuum in the engine under closed throttle and thus affects ancillary equipment. Any truth to that?

 

HAHA We have some local guys called that!!!!

 

why is it LESS reliable? What makes it LESS reliable. Please excuse the noob question as i am an X piston guy

 

No need to get snappy here. We are only here to help. And the reason why I asked, is because your description was so vague, I had to ask. Last I checked, my crystal ball is really dusty and still deep in the closet.

With that said, I would recommend a streetport to start off. Also, if you would have used our forum's amazing search functions, this topic has been covered thousands upon thousands of times for FD's.


Welcome to the forums.

 

I ve never seen a torn down Rotary angine. but aint that Streetport the equivalent to an ported head on a piston engine?
How much power can be generated on a rotary with such a mod?

 

Just for you German

I guess my real concern here is this. If I just get it streetported now, and decide down the road that I want to get full bridge, then I really spend more money because of the added labor to remove everything again. So I guess what I'm thinking is that I should just go with the full bridge now. Many have told me that the powerband will be wider across the board and this really is what I'm looking for. Plus, with it being dowled and pinned, it's got to be stronger, right?

 

what HP are you going for? that is the big question.. or is it the brap brap sound you are after? do a large street on the prims and a large bridge on the 2nds it will sound good and make good power on the bottom for street use and still let you stretch out the rpms
