i have a Question, i just bought a Bridge Ported FC, only 2000 miles on the engine, for about $3500 its a 89 Turbo, and i was wondering how much boost i can use?, i have 3" fully exhaust, stock turbo, stock boost gauge, and everything else stock! now i was just wondering if i could even race it or not race it , i dont wana blow my precious car, and how much boost can i use? im sorry for the long post, but i need some help thx guys, u think i should get a new ECU?

 

you should be at 9 or 10 pounds with 3 inch exhaust.. now about the bridge port on a turbo engine.. the guy that had it before u must've been kinda out of his mind.. lol are u plannin to use it as a daily driver?? if so expect very little mileage in the future from that engine.. sorry to say it bro

 

yeah i know the mileage is gona suck, but oh well, im gona be at the track almost every weekend though , all i was wondering if i can even REV it past 5RPM, i was told i would blow my ECU or something like that, i know i need to get a boost controller so i wont spike up but i just need to know if i can rev it past 5RPM

 

Do you have any fuel mods?

 

nope, no fuel mods , stock fuel system, .......should i get a boost controller and boost gauge, and keep the boost LOW?, cause right now i dont know how much boost im actually runnin, so u think thats the first thing i should get in the car ?

 

Hmmm, I wonder, how's the idle, and where's the idle set at?

 

From what I've been told (looked into BP'in my 3rd gen on stock turbos), the BP will spool the turbo so fast that it will basically self-destruct if you try to race it. I've been told that I couldn't even hit the BP's powerband on the stock turbos. Since the T2's turbo is a little bigger than one of my stock ones, you might get a little more rpm's out of it. Good luck though, BP's rule, BTW mine was to be a track only car.

 

Are you even sure it's bridge ported? what's the idle at? I'm amazed anyone would bridge port a motor and leave everything else completely stock. I actually don't believe it but I will take your word on it if you insist.

First get a boost gauge.

A boost controller will not keep your boost down, it can only raise it, thats the last of your worries right now.

You should take it to a shop and get your exhaust analyzed to find out if you are running rich or lean. Then get an air/fuel gauge and/or EGT gauge.

After that to see any boost safely you are looking at fuel mods --- $120 Walbro 255lph pump, $300 Apexi S-AFC, $150~ additional injectors 720CC min.

In the meantime try to stay below 5000rpms and try not to get on the boost. I have no idea how a bridgeport is going to deal with stock turbo (or vice versa) so go easy on it.

edit: I am an amateur here and basing the above info on what I've read and been told many times over. I'm sure someone more experienced in the way of a BP will correct me if they think my advice is wrong.

 

wow, thx for the advice guys, the guy Bridge Ported the Engine cause he was gona make it a Dragger, but he didnt have enuff money and got into alot of money Problems, so he had to get rid of it, so i bought it from him, , so Fuel System is the thing i should get first then?

 

Idle? Engine pics?

 

Well, fuels system is the 1st thing to take care of..

After that you will most likly have to upgrade to a standalone ECU.. I would not think the stock one could handle the flow the engine will put out..

And the turbo you have will be absolutly usless.. You will need at lease a T04 turbo.

mine Idles at 2.5 when its cold, then it drops down to 1.25 around there, ill have pics up soon though, ill take pics of the engine bay, and body,

 

Man, $3500 for a bridgeported series 5? F'ing A.
