Anyone with a turbo half bridge port?

Anyone on here running a turbo'd half bridge port? I know that Soul Assassin has one, but I want everyone that is running one to reply (You too Soul Assassin).

I need help on deciding what to do with my new engine. I am VERY heavily considering a half bridge port. Right now, I have a to4e 60-1 with .70 on the intake and a P-trim .96 undivided A/R on the exhaust.

I'm considering putting a 1.15 divided housing and a divided manifold on the turbo for this setup. I know that with a bridge, the power comes on late, but is this too big of an exhaust trim for this setup? Should I go with maybe a .81 or .96 divided setup to help with down low power?

What is the power band for one of these engines with a halfbridge port? I'm thinking 4500 - 9000, is that about right? This is going to be a street car, but not a daily driver, except when I feel like it. I'll probably put 6000 miles on it a year or so.

When my engine gets built, I want to know how well it should be built (I'm talking revs here, what should it be able to SAFELY rev to and hold 17 psi from this turbo?).

Half bridge is when the secondaries are bridge ported.. and the primaries are street ported...


This is good so you can run a 2 peice apex seal backward and not eat corner seals...

It also helps alittle with the low down power...


BTW Exit13B is the one who has a half bridge i believe..

I have a half bridge i did it myself it was really loud,it pulled really hard all the way to 8500rpm. rwhp was about 550 with 27psi with out ice. i think it could make over 600 with proper porting and tuning. i broke one of the end plates ,or at least the dowel did. i may bp again if i can find a way to make it easy on my ears. NO FLAMES PLEASE
oh i have an FD and i am black and no i did not steal it last time i post hear i got flamed because of it,and my grammer i thought i was in the supra forum.
hope this helps you

Well, for starters, saying crap like that is a good way to get flamed. All 2nd gens are NOT slow.

A 2nd gen can be just as fast, and use the same exact engine mods any 3rd gen can use...

Nah, he is saying that cause he posted his turbo system for sale and a few jackasses without turbo rx7s tried to clown him and say the turbo system was stolen, so he has a right to ask some of you jackasses without a clue not to flame him.


But jim, and als cars are fast

Ok my car went 11.1@133 with out ice.
I do not think i know every thing soul assassin,I AM SORRY ABOUT THE 2GEN Quote your car is really nice we have the same rims.Greg you are a good man hope to sell you out there next year. Respect.
My car is in the IDRC street class,fastest car is high nines John sheperd. Crispeed car would be in the outlaw class,with cars like EL ORINGINAL and QUILES low 8 sec cars and he only went 9.2 the Quick class cars go 8.8 So we're both off the pace.
ALL BLACKS ARE NOT THEIVES all i want is my respect

I don't think that anyone knew you were black until you said so. I think that everyone was playing around with you because you used all caps in your ad. Usually that's taken as screaming on the forum.

First off!
My car is legal for the Quick class if I wanted to run it there but I choose not too!
As for being off pace the only one here seems to be you with the combination you have it should be a lot faster. One of my customer's (BOOSTEDRX7) 2nd gen run low 11's on drag radials at 130mph with a secondary bridge TII motor at 20 psi of boost without the use of NOS and it's producing just over 500RWHP at that boost.

that is un-called for, ive never replied to any of your posts ever! i actually searched through your damn profile and all your threads/posts..not one reply from me

you have one big ego there with your giant GREDDY t88 turbo and fd. you think your all that don't ya? i think i want to get a big huge turbo now just so i can hang out with like you all the time.

yes "slow *** second gen idiots" i believe they were running 9's when you were in diapers. no one talks **** here except when someone goes out of line and you have.

this section is a good source of information for those who are considering going single, as well as those who already have them. take your bs to the lounge if you want to talk ****.

I saw you guys reply to my post calling me a thief and then it was edited by the moderator; you guys post so much crap you don't even know what and where you post.
Crispeed I have no beef with you-- I guess because you're overweight you could run in the quick.
Supras with full interior and beats run low nines.
Was I wrong about the cars and their times in your class?
Anybody can qualify in the outlaw class most of the time they only have 5-6 cars unless its summer slam.
you are right-- 3rd yr with rotarys 2nd yr building motors and my first porting job and 1st BP and going 133. I'm happy low tens are my future. I do not have a big ego. I responded to something that you said and now you guys want me to race your "king". Well bring it on! I'll be at Summer Slam next year. Bring Zapco.
