single turbo coversion

Hi,

 

Im going through a single conversion from a standard twin auto "94

going for around 500bhp.

 

it has a cheap ebay turbo on it at the moment (from the last owner), so im litterally never boosting at all so i don't scrap it .

 

I've had a turbo specced and custom ordered from Turbonetics

 

The question is, i have the new 650cc side feed injectors and 350lpr fuel pump sat waiting, can i put them on now without a fuel reg? and still run the car?

It has the pulsation dampner bypassed allready.

 

cheers,

tom

I was thinking this, i will be getting an aem fic8 piggyback, however will all of this need to go in at the same point? meaning i can't put the injectors and pump in before i put the ecu in...but then surely i can't put the ecu in and map it without the injectors or pump in?

You could do the pump and the turbo kit. But just drive it without boosting it, then swap in the injectors at the same time as the FIC. I think that should be OK.

 

Not the way I'd do it, but it should be OK.

 

I take it the ideal way to do it is to do it all at the same time? The thing is i do pretty much all of the work on the car myself, apart from obviously the ecu install and map, meaning i don't want to have to pay for someone else to do it all for me when i can d the pump, turbo and injectors myself :/ ... don't really know what the best option is

Do it all at once, however inconvenient. Not worth the risk of engine damage otherwise.

 

That's pretty much what i needed to hear haha, would it be ok for a short drive when all of it is done bar the ecu and mapping? as i will do the injectors etc. myself and is around a half hour drive to the tuning place that i am going to?

You cannot run the 650cc injectors with stock management. It probably wouldn't even run.

If you really want to fit all the parts yourself, take your ecu to your tuner, and see if they can install a base map, with the correct injector values set

 

You might then be ok to have a gentle drive there, for full mapping - buts it's not ideal.

 

If you're using side feed injectors, I presume you're keeping the stock rail? If so, the stock fpr should work, providing you don't need to adjust the base pressure of your fuel

The fic has injector size correction all you would have to do is put in the old injector value 440 then the new 650 , it will then populate the hole fuel map with the correct values, but you would have to wire it all in correctly,

I have a fic 8 so please have a read of this thread for some pointers :)http://www.mkivsupra.net/vbb/showthread.php?258004-single-turbo-with-a-aem-fic-information-thread

350 will be in its limit at a round 600 iirc

So you reckon get the ecu Base mapped for the 440 and the put the 650s in afterwards? If that works it sounds like a good shout...

 

I won't ever be going about 550, so 600 as a limit is ok, as long as this doesn't strain the pump? Also I was going to get the walbro 400lph, but at the mo I have a Kemso pump...are they a crappy brand?

 

Cheers :)

The fic is a piggy back ecu having everything in all the map cells at 0 will be your base map, you just have to do some set up stuff but I could send you the values for that.

Saying that I could send you my map as Im single turbo tt auto with 630 injectors and that should see you to your mapper for a propper map to suit your setup, but you must fit the fic correctly and everything else other wise you could be in for a nightmare

The thing is, I have always done everything parts wise on cars, would happily rebuild the engine and box, but to be honest, I don't want to go near the ecu and mess it up as I havn't done it before...I'm not even sure how much of a task it is...I need to try and find a tuner near me that will do the car first haha, as its hard to find anyone...

The chances are I will go for the aem one that you have iirc? If so how could you go about sending me the Base map buddy? :)

 

Cheers

If you not confident with wiring then I would give it a miss lol.

Best thing you can do is down load the AEM FIC8 instruction manual and have a look at whats involved , its not that bad but then I deal with wiring in my job,

As for sending the the map I can PM you it if I fire up the old laptop lol

Lee p might still have this one http://www.mkivsupra.net/vbb/showthread.php?326958-AEM-FIC-8-(Fuel-and-Ignition-Controller)

You really need to find a mapper first as if they cant map it your stuffed even though its very easy with the fic

 

You cant really mess anything up ecu wise its a very simple ecu which can only retard timing and adjust fuel everything else remains under the control of the stock ecu.

 

I just have to zip the file to send it and you will need the aem software to open it bud

I had a look at the instructions last night, looks ok to do...

 

Have just asked Lee P if it's still for sale :)

 

However I'm trying my best to find a mapper/tuner around where I live...at the moment it's not looking great.

 

Thanks for the on going help :)
