420A with Star Kit. What engine management?

[Hybrid4g64Spyde]

As the title says. I have a customer with a 420A Talon with the Star kit. I am replacing his turbo with the exact same one as the kit came with, the original has major shaft play, and broken fins. He is looking for 300whp. What engine management system could we use on the setup. He is also beefing the fuel system up, what pump, FPR, and rail should he go with? Also, what wastegate would be ideal for the setup? Tial? I know for a fact the Turbonetics Deltagate is a piece of junk, so I need to replace it. I am installing custom grind cams on it, and a 3 inch downpipe right now. Any help would be greatly appreciated. Mods, if it is too simple for me to search, tell me so, but for right now, I need answers now.

it depends on how detailed he wants to go
there are not a lot of options for our cars
some systems will work but are not officially supported
check out the megasquirt system
there is a lot of discussion over at 2gnt.com about it
it can control any size injector and still maintain stock fuel pressure,
spark, it can activate nitrous and water injection, engine fans plus it can be tied into a wideband and set to always maintain a specific afr throughout the rpm range

all in all it costs about a grand for everything needed

ms unit is about 300
then you need the wiring harness, new injectors, 1:1 fpr,
wideband plus some special easy to find coolant and air temp sensors

You own a shop that works on cars and you even own a DSM, but yet you are here asking these questions? Whats the name of the shop just so i know to avoid you...

He asked for your help not your attitude. He is asking so he doesnt have to jerry rig it. Sounds like a good owner to me. Someone who would take the time to research something instead of screw it up.

ya he doesnt own a 420a, and is researching before he does the project. i would rather have that then some shop that thinks they know what there doing and doesnt and messes something up.

as for engine management, the megasquirt is the new big thing that i would look into.

My point comes from the question....

"Does the customer know that you have no idea what you are doing?"

Honestly, were you straight up with the customer in saying that you don't know what you are doing but you will find out? If I was to take my car somewhere and the guy said he didn't know what he was doing, you wouldn't find me leaving my car there.

actually now that i re-read it your right. the engine management question i could understand. but he also asked which fuel pump, fpr, and wastegate. these are universal things that he should know

Not a universal thing. If I owned a shop, and new about every single piece of information about every aftermarket peice, I would clean up.

Give this guy a break, there is lots of choices when it comes to a fuel set up, and the fact that he took the time to double check and see whats on the market for his customer shows dedication. For he knows someone could have develped a better fuel pump or Fpr or whatever else, and if he didn't check on one of the forums he might not have heard about it right away and, at least to he's asking to find out any possible new information about parts for our cars.

The guy at the shop who installed m SAFC2, hadn't installed one in a 420a Eclipse before, but he didn't on other cars. Now because he was smart and check up on how things should be done using this forum, he found out it wasn't a good idea to do the blue wire mod. He also asked where to get some wiring diagrams before he just started plugging away, again back to this site or 2gnt, and thats all he needed.

Good luck with your customers car man.

Thanks guys, I am very happy to see you guys seeing what I am trying to do. I do not own a 420A, I have a Hybrid 4g64/4g63. I am still in search of what parts you guys would recommend for this guys car. Where can I get prices for the Megasquirt system? Would I be better off runnin an AFC instead of a whole engine management system like the megasquirt? Thanks for all the help.

SAFC you run the risk of advancing timing to much, to find prices for Megasquirt, search on 2gnt.com. Fuel system, i would say stock fuel rail is fine, run an aeromotive 1:1 FPR is your are gonna go with the Megasquirt, no megasquirt go with a vortech s-fmu. Fuel pump, walbro 255lph seems to be the most popular.

i believe the ecu only advances timing when you lean out the mixture because it sees a lower manifold pressure then it should. if your using it to richen the mixture up a little it wont lean it out.

what it basically comes down to is how deep are your customers pockets? if he can afford to dish out $1000 to buy the MSnS and all its components then go with that. if he doesnt have that money then a s-afc might be a better choice

on 2gnt.com MrSlick is the person to go to on getting a MS built
it runs in the neighborhood of 300ish

and he supplies the base map for your car
you then need a wiring harness, air and coolant temp sensors which can be found at http://www.rs-autosport.com/
on top of the injectors, 1:1 fpr etc

they also sell prebuilt MS boxes but no base map

the software to tune a MS with is a free download

 

[WHite97RS]

yeah thats who i ordered my MS from. 285 shipped. Cant wait.

 

[baxsom]

where are you getting your harness and sensors from?

 

[WHite97RS]

i havent decided if im gonna make the harness myself or get mr. slick to make it for me for an extra hundred. im pretty sure you can pick up the snesors from like advanced or auto zone.

Aight, latest on this customers 420A. We noticed a lil, well, alot of rod knock, so we decided to pull the oil pan and check the crank. Well, we looked up at the innards, the car has JE pistons, Crower rods, and ARP fasteners. So, we popped the number 1 cylinder out, and the rings didn't have sufficent pressure, so the piston skirts were fizucked from the piston slapping around like a rag doll. So now, the guy has to replace all 4 pistons and rings. K, should we still go ahead and tune with an AFC or not?

My honest opinion is to go with the MS just cause it is the same price as a SAFC but does so much more. Only problem is the MS has a slow turn around time, ive been waiting on mine for a month and still no MS, but these things are avaiable in a DIY kit, im jut not competent enough to do it.

the MSnS unit itself is only aruond $300, but after all the other stuff you need, the total price ends up being over $1000. plus the s-afc is much easier to install. dont get me wrong, the MSnS is great and i plan to ditch my s-afc for it one day, but its not for everyone
