The HKS GT wastegate should be able to fit the bill since you're planning on running so much boost anyway. I know that you could get 1000 HP. People are getting closer to that everyday with 13Bs. You didn't define what you meant by minimal lag. 4K RPM's is a fair number. 3 T3/T4 hybrids would probably do a nice job because the T3 turbine section will spool quickly.



A big single is usually easier to select, but the 3 turbo setup may yield better results. I picked up a Garrett T-76 (not the same as a Turbonetics T-76), and the specs seem great for a 20B, but I'm trying it on a 13B. I hope I at least make full boost by 5500-6K. If I ever get the manifold finished and do the motor I can let you know how it would translate to a 20B.

So you want a bridgeport, boost at 4000 rpm's AND streetability?



I don't know how that's possible...A bridgeport for the most part is unstreetable...I have heard one in person...It's louder than most competition sound systems...

dont know much about this subject but i do have a pic that might help

jspecracer7

like I said...plumbing nightmare...and to deal with that on a daily basis...IMO, I would forget about it...I'd get just as much power from twin T300S's...

it wouldnt be a daily driver. just a weekend money maker like down in myrtle beach where everyone shows their ***.



depends what u would call streetable. to me a bridgeport would be fine.my car is already loud as hell.and its scca legal.anything but a pport.



hey ace that would relate to about 4k rpms on a stock 20b if u r getting 5500-6k on a stock 13b.its the same with the t51r.i talked with m2 about it.



and as u notice by that pic it doesnt take a huge friggin radiator to maintain a 20b.plus i will be v-mounting radiator/intercooler and have a scoot hood on the intercooler's top side.a ice tank on the bottom side.this will take me a few yrs.i found a site that sells the carbon fiber doors and 3 rotor cores ive been wanting.i dont need the whole engine.especially when i would trash the rest anyways.



im dry sumping the 3 rotor and pushing back 5-6 inches.this will put it in stock position.plus i wont have the manifold in the way of the firewall.



i will go with an electromotive tec 3.



yknow the funny thing is when i explained this on the other forum.i had alot of ppl backing me and then came jimlab.hes cussing me and downing me for everything im worth.nothing but a dream that i wet myself to at night and regurgitated while i was on the *******.



but i definitely will keep u guys posted on whats going on.its gonna be a shame though.i gotta go somewhere for uncle sam for 1 yr or less,thats all they would tell me. so i gotta start when i get back.

Your basic plan sounds good. Now all it's going to take is time and money. I'll definitely post my results with the new turbo whenever I get it in the car. If definitely has 700+ HP potential on a 13B. So it would easily get you what you want. The only question is the spooling time. If it spools too slowly then I'll throw in a smaller exhaust housing.

the 20b has more torque down low so a laggier turbo wont be that big of a deal.

Yeah, that's what's so nice about them.

well ill also be running a 3 plug option.i will have 2 leading's side by side and a trail.i dont even know if i will want to run a trail.i might just use it to cover the hole.or i might run all 3 non split.unsure at the moment.

Are you doing the conversion yourself or are you taking it to Brian at Rotorsports? I might have to swing by Fayetteville when you get done, i'd love to check it out.
