bridgepoerted turbo II carburated?
 
hello guys
i have a couple questions.
i have an 88 rx7 that has been swapped with a bridge ported motor.

i don't really want to go keep it fuel injected because of cost issues.
with the Bridgeport i need a stand alone ecu, different intake setup and fuel set up.
and of course find a tuner that can tune the FMS i would get. which is hard to find around here.

i have done a lil bit of research on converting 13b motor into carbonated, and i found a couple set ups i can use
heres is the jay tech intake manifold for carburetor.

or the racing beat one

i read that u can do the "blow trough" method or something on the carved so it can be boosted with good numbers n work good.

can someone that has done this or know about it help me out?
i would really appreciate the help.

any suggestion on what parts to use of what to do would b great
thanks in advance

Lol u are worried about costs with a boosted bp motor and u think going carb will remedy that?

get an rtek 2.1 and doing it your self with the stock manifold, is THE cheapest option. and you'll likely make more power.

If you don't have a decent local tuner and you don't want to spend a lot of money, then I suggest selling the BP engine and installing one with stock ports. Tuning a carbureted turbo engine is WAY more difficult than tuning one with a standalone EMS. If none of your local tuners can tune the NA BP engine, then they will blow up your engine for sure with a turbo.

How is the car running now? :scratch:

I don't think the Rtek will work on a full bridge unless it has the AFM-delete function that has been postponed indefinitely.

Really depends on how much power, and what turbo he is using, stock turbo? rtek 2.1 won't need the AFM delete.

Well its more of a finding a tuner thing.
But it was just an idea. So I tought I'd ask
And I would like to have the AFM deleted. I was told the way to get that deleted would be to get a haltech ps1000? Idk if there is any other FMS that can have that deleted.
Can the rtek have that deleted?
N I would b using a ht60 turbo or somthing simular in size. Maybe a lil smaller.
Or any suguestions on what ecu I can use to be abel to delete the AFM and work good with the bridgeport.

I don't think you want to use a smaller turbo on a BP. Go bigger

For cheap EMS that'll let you run without an AFM, try megasquirt if you're electrically savvy. Next on that list would be a Microtech

What is your budget?

frijol 05-02-11 07:18 PM

iv never really done any wiring like that, not completely like those probably require.
shouldn't be hard if its all labeled. i can figure it out if they are. since there would probably just injectors, the 2 intake sensors and what else is there to wire?
im not completely clue less lol

and my budget is not to low but i can spend about 700-800 for the EMS.

i was thinking about power fc since it plugs into the same wiring harness with no need to rewire harness.

but i was told u can't delete the FMS?
what megasquirt or michrotech would work?
is there different kinds?

thanks for the help
really appreciate it.

You are going to need a tuner for a bridge ported engine because there are no pre-set or auto-tuning EMS units for it.

Every common standalone EMS will work in speed-density mode, which means no AFM. Most piggyback units and ECU upgrade chips require the AFM.

No

The HT60 about the size of a Garrett GT4202.

It would be a good idea to visit the EMS websites and look at the manuals to see what you are up against. A typical EMS has about 20-30 wires.

Your budget is too low. The entry-level EMS units are the $950 Haltech Platinum Sport RE and the $1,100 Microtech LT8.

http://microtechefi.com/microtech-pr...p?product_id=3

The PFC and adapter are $1,310.
http://banzai-racing.com/store/S4_PFC_adapter.html

Add to the above about $1,500 in fuel system upgrades, $900 for a turbo exhaust system, $475 for a clutch kit, $400 for a crappy Ebay FMIC kit, $200-300 for a good BOV, $525 for an upgraded radiator, $75-500 for electric fan(s), and probably about $500 or so in other components like hoses, belts, fluids, etc.

Do you realize that a turbocharged BP 13B makes over 500hp, and that it is going to require a lot of money to support this power level?

Amen! Haha
N ya I no it will take a lot of $$ but I have a lot of the stuff like greedy fmic. Radiator, fan, hks bov, n other stuff needed.

N so will the pfc be abel to have the AFM? If so ill probly get that n use the stok harness. N the budget was just for ecu. Not including all the other stuff.

Thanks for the help.

I'm selling my Haltech E6K for $700. It will run anything you throw at it.
