So I'm picking up a stock 13B that was converted to carb using a racing beat intake and weber 600 carburetor. I want to rebuilt the engine and do a bridgeport on it. And I wanted to know what other mods I can do to the engine while its taken apart for rebuilt. I would like to get over 200WHP out of the engine and be able to keep it streetable because I will be using the car daily

 

depending on what year and model engine you have you actually might be in the 180hp ballpark already....

 

The engine is out of a 1985 gsl-se

 

I am doing the same thing. I am looking for a ballpark as well.

 

racing beat sold the dellorto kit and "streetport" exhaust, and said it was 177hp at the flywheel

 

How will u daily it wont a bridge port kill mpg?

 

my friends bridge got 26mpg!

 

Omg how? I was gonna go 1/2 bridge. Onmy sa cause of gas

 

he spent 3x as long tuning the carb as he did building the engine, and a tall overdrive in a light car.

 

I get 21-24mpg with mine. I know there's more fuel economy in the ignition timing (it WANTS a three dimensional curve, it HAS a one-dimensional one) and I think the exhaust is still too restrictive, but for now I'm pretty happy.

I did just average only 18mpg on a banzai run to Columbus and back for the Audi club meet, but it's maybe 20 degrees out so the engine is only running at 155f coolant temp, and I've got King Kong sized snow tires on it (205/60-15 front, 235/45-17 rear) and the rolling resistance with them is crazy.

On the plus side, now I have a good 5cyl head to port for my turbo Quantum project, and the Mastercraft snow tires really don't give a crap about no inch or two of snow on the ground even at 75-80mph...

 

Anyone have an intake for a 12am?!

 

and then you can start research into quantum mechanics?

 

Different quantum

 

so there isn't a whole branch of physics devoted to getting those things to run?

 

I have a similar setup just make sure you adjust your timing and make sure you have the right jets.

 

Well, it's weird. If there's a drivability problem, it won't act up if you're observing it.

True story - One time the car was running hot on the highway and no heat. 5 miles later I pull into a rest area. Coolant is full, upper hose is hot, fan cycling. Huh. Get back on the road, we have heat and coolant temps are fine. Observation changed the outcome....

 

:head explodes:

Peejay,
is that Synchro (just looking at the ride height)? also what head did you get? 4 valve?

 

That's not my syncro.

THIS is my syncro:




I have just another JT 10-valve head, but it's supposed to have a better casting for porting than the turbo engines had. Supposedly it's easy to go fishing in a water jacket if you try to port at the valve guide boss on an MC head, and the valve guide boss is something like 2/3rd the width of the port so it's where major gains are to be had.

No oversized valves for this one, but I did spring for the absurdly expensive super-awesome exhaust valves that will tolerate any EGT I can throw at them without losing their heads like the stock sodium-filled ones.
