Ok so i was doing the internet search and found a great carb for a big street port or bridge port turbo 12A setup, its a Demon 850 most ofthe carbs that are boost prepped are like 800$ but this place is cheaper might be able to get a group discount of like 10 or so i talked to the for a bit and he just builds these cuz hes retiered.

Carb. http://wpsracing.com/ca850cfmmide1.html 583.99

Intake 12A http://www.racingbeat.com/FRmazda1.htm 262.00

Intake 13B http://www.racingbeat.com/FRmazda1.htm 268.00

Manifold plate 12A http://www.racingbeat.com/FRmazda1.htm12A/13B 24.00 + welding of turbo flange to pipe and engine outlet

Turbo your choice mine would be t3/t4 hybrid ar .57 trim 130.00+ plumming

Grand total for turbo kit base price without add ons or plumming 999.99 wow didnt plan that.

 

you might be able to have the guy make a demon 600 boost ready that would be good for a stock 12a and it might be a hundred less.


Hey Doc if this is in the wrong place to post this sorry in advance.

 

update found the 650 cfm carb that would be perfect for a stock engine.

where are you getting turbos for $130?

 

ebay has standard t3/t4 turbos oil cooled for 140 all day long brand new.
this is all in choice like a said you can go big or go small im working on setting up a system that works for a stock 12a and a 57 trim t3/t4 is in that budget range.

 

Last time I checked all of those turbos have a .63 A/R t3 exhaust side which is a little small.

 

DirectFreak informed me that a .90 or somewhere in the 80s would be best for my setup. Too bad I'm a little fuzzy on turbo lingo at this point. But I'm learning!

 

yes for doing 12 pounds and having boost in the higher range a 70 trim is about perfect but the 57 boosts quick and doesnt flood the stock engine with PSI

Im still working all the math for a stock engine i need a donor engine that i can test how much it will take so im looking around for a running 12a once i get it ill put the stuff on and boom test it....lol

 

your right on the .57 for a quicker spool, but home boy up there is correct on the turbo sizes that ebay offers...Every once in a while you will run into something different with a different size and what not, but you have to be on the look out..but there there...

For a g bar that is not too bad tho...actually that is not bad at all...but you could save a lot of money and test your luck with a buying a used 12a holley intake manifold...

The waste gate, running to the air or just re route it back into the plumb...your call...Dont forget the carb hat...they run like $100-$150 all day on ebay...or you can find them through a outside source...

 

+1 the .8 t3 seems to be really nice however

 

You can save some money too - a Simple S5 TII Turbocharger is almost perfect. It's a good size, and offers decent power (over 300whp),
and plenty of low end torque. Add and external wastegate, and you're golden.

A T3 is wayy too small.

A 63 hotside is too small.
(You will overspin the turbo, run hot air, and choke the exhaust.)

For a Street setup that isn't laggy/top end only - keep it the hot side between .80 and .96.

Here's some good Turbo Info

 

do not get a demon they suck ...i purchase one boost prep my *** i had fuel leak from three different places on the carb.i had fuel spray on the turbo. i don't no if i got a bad one.but F@#K.... i could of lost the car to fire. i had to use gas resistant apoxy on a new carb.....fU@K B.G.

 

did you buy a used one?

Demon is the bentley of carbs man

if not, do you not know what customer service is right you call them and say hey you sold me a broken item and they tell you to send it back and they will send you a new one........i had 2 demon 850's on my 600WHP camaro and never NEVER had any issue in 3 seasons of bracket with it.

 

a new one .... the base plate machining suck and fuckup ..i call b.g. and they seid to send it back to them...i have to pay for shipping to send it and to get it back....F@#k f@#kERS........IT JUST A FANCY LOOK HOLLEY....i got jerk......now i build my own holleys and send my base plate to the carb shop to get boots prep ......aka customcarbs.com

 

if you buy th carb from Jegs they wont risk having bad reputation so they are the better choice for service they also can get the 575cfm carb

 

jegs, no doubt great services.....i will stick to my holley...

 

Nick, I think that the only way you could blow a rotary faster than you have in the past is by adding boost.

This should be interesting though. I look forward to seeing how it turns out. Good luck man. ..

if he follow the rules he wil be ok....good engine parts....fuel...timing...and good turbo. not a ebay one . s5 are great like directfreak sed.. i have seen cheap turbo explode like a grenade

 

Demons are one of the nicest carbs out there.... never dealt with a boost prepped one tho... i have a few buddies that wont use any other carb!

 

........."bah humbug"......
