okay after some searching iv discovered that its basically the same price to purchase a megasquirt kit and assemble it ,injectors,and fuel pump..as it is to buy a carb,intake,fpr,and all the other little things i need.


my motor is going to be a s5 t2 block with a half bridgeport and s5 n/a rotors . that im going to run n/a for awhile till i can get a decent turbo as the stock s5 turbo will be spooling to much with the port job.

the only injectors i have are 460cc are these going to be enough to run this motor as n/a till i upgrade to turbo?then of coarse i will upgrade injectors and fuel pump.

i will have to do the tuning myself either way atleast the rough tuning due to funds.
now a carb is easier to tune i guess then a megasquirt but seeing as i know nothing about neither im gonna have to learn anyhow.


so my question is which for my application should i choose? now i know that a efi setup in most peoples eyes is far superior to a carb but keep in mind that im on a 500 dollar budget. and this car is going to be daily driven with autox on the weekends.

 

I've never dealt with tuning a carb on a rotary but I have messed around with a megasquirt on a rotary and really it is not difficult. In fact, after megasquirting my rx7, I went ahead and did the same to my truck which used to have a carb. I personally think it is easier to properly tune an efi system than carb in that instance but that is just my personal experience.
Also I think your budget of 500 dollars is going to be a little small for each option. For Racing Beat's carb and manifold it is approaching $1000 and there is a lot of little things needed to make megasquirt run. If you spend your money wisely and do the tuning yourself the megasquirt will be cheaper.

yes i relize the cost but im talking about buying used componets.as far as i can tell its going to be

100+for a carb
250+ for an intake
100 or so for a fpr
and + all the little things

and then for the megasquirt

alittle more then 200 for a ms2 v3 i think 240
then most stock sensor can be used i think
then really i ahve nothing else but the couple addons for a megasquirt
possibly injectors but they cost no more then 100 used for my application
so that still leaves about 200 for the extra wiring and sensors i might need to buy

 

It is going to be difficult starting your rebuilt engine for the first time on megasquirt unless you know what you're doing.

 

Carbureted bridgeports are terrible. It should never even be considered.

Based on your questions I'm not sure you have the knowledge to get a Megasquirt working. This is not an insult, but a reality check. I've seen every thread and question you've posted which has given a good idea of your general knowledge. If you are going to continue on the Megasquirt route, find someone with experience.

 

thats got to be the funniest **** ive ever heard!! LOL

ROFL!!!!!



some of the fastest streetcars run a ida style carb fyi

 

Everything works great at wide open throttle.

I've done my dues with Weber carbs and bridgeports. I've seen people struggle for a long time with Holleys and bridgeports.

All the bad press that bridgeports get is the fault of the carburetor, not the port. For drivability on a high overlap port, nothing can come close to EFI.

Carburetors are for lawnmowers, and only then in the most dire of circumstances where there's no space to mount and ECU.

 

Well if you're going to be turbo eventually then why bother with stuff that you'll have to undo later on, I'd say go the megasquirt route, as you'd be able to re-use it later on, so it won't be money "wasted".

 

i agree with the megasquirt route. with your future goals it would seem counterproductive to revert back to a carb, with standalone, the tuning possibilites are much more refined. besides, tuning a turbo motor with high comp rotors would be sketchy enough with standalone, so i can't even imagine with a carb.

 

Megasquirt for sure over the carb.

On another note, S5 N/A rotors are pretty high compression for forced induction. Might want to think about S4 N/A or S5 Turbo instead.

 

Save your pennies and install an Autronic.

 

Megasquirt is a tough route for someone who is getting into standalone tuning. I did it myself on an n/a setup. There isn't as much support as Haltech etc. That doesn't mean the Megasquirt is inferior, it just means that if you get stuck there aren't many tuners who will mess with it and less support online.

 

Megasquirt for sure.
