well I am finding out that I wont be able to run my twins in sequence with the megasquirter so I am looking in to a single .heres my ? my setup will be 13b re mated to a 2 speed powerglide or turbo 350with a tcase for 4x4 in a stretched geo tracker frame toyota axles and a samurai body(just skins) this will be a pro arena tuff truck and will weigh @ 2300lbs.I need to get maximum torque and a turbo that spools quick most races are under 60 seconds I dont really want to tear the motor apart either just desmog install megasquirt .what is a good turbo kit for me ?and what other mods can I do to make this thing scream. and I did search

 

cheapest thing to do would be to set the twins up in parallel...

I don't know what a megasquirter is. Explain and maybe I'll change my answer...just maybe.

 

megasquirt is an inexpensive DIY fuel injection system.

 

Set-up twins in parallel and run up to 12psi with stock fuel system + megasquirter.

 

I guess if you still wanna run them in sequence your gonna have to go with a PNP system, I.E. the Power FC, not sure what the price is for either but i'm pretty sure the PFC would be more expensive.

Good luck

 

thanks how will that affect my powre range ? will it be all high end or will there be alot of lag?

 

it will be more lag than seq. but set it up right, remove all the flapper doors in the manifolds and y-pipe...free flowing exhaust with propper boost control...upgraded IC, etc.

Umm...how come your fuel computer won't let you run seq?

 

I dont know that is just what everyone has told me .I will be running pretty much no exaustI was looking at the 60-1 kit on ebay is that a good setup for what I am doing

 

no, don't buy that kit...to go single properly it will cost you double what that ebay kit is going for.


wished I lived closer I've got a buddy in VA that builds rock crawlers...I've got no doubt we could get your rig running seq.


do you have the stock ECU? Why are you running the mega squirt? is it piggy back? if you run no exhaust, you will need more fuel than the stock ECU provides. <---that's going to be extremely LOUD.

I would limit boost best you can with no exhaust...you might have to look into porting the WG of the twins if you stick with them.

Another alternative would be to find a use PFS (peter ferrel supercars) purple piggy back ECU. It will allow for seq and more fuel and less timing. Probably find on online for ~$300.

post something in the For Sale section.

 

i have the stock ecu and it was modded by re ameia also have the engine compartment wiring harness just cant fid a wiring diagram in english .and also I ahve removed most of the emmisions equip will that matter? I have been contempalting running 3"pipe back to a magnaflow but that wont restrixct much .

 

3" back with a small cat (and the magnaflow) in there will flow enough and give some back pressure...I just don't want you to blow the engine after you getting it running.

removing emission's won't do too much harm...might make your idle lumpy since you removed the secondary air injection.

why do you need the megasquirter if you have a modded ECU?

 

dont know where all the wires hookup to the harness is cut where it gos in the cab so I need to know what all the pins on the ecu go to and so far I cant find anyone to tell me or give me a wiring schematic

 

how about I send you a harness you can cut up and splice...it'll be color coded. Then you can use the stock ECU, right? OR if you want...you can send me the harness you have, and I'll do the work for you pretty cheap...here is my resume' https://www.rx7club.com/3rd-generation-specific-1993-2002-16/electron-manipulation-336924/

I can probably make the harness reach probably any lentgh you specify. (you won't be able to tell where I splice it either ) IF you wan't the same disconnect connector, I can do that also, but it's $extra$

there is an online workshop manual. Try and search for the site. www.iluvmyrx7.com or something similar.

 

I would like that .and I would appreciate it .save me a whole lot of time and money.can you pm me your phone # or something and I can get your addy and send you this stuff.
