Need help... 420a build sheet.

[MrMopar426]

The 2.2 stroker Kit Includes: Clevite 77 or Federal Mogul Rod Bearing Set Clevite 77 or Federal Mogul Main Bearing Set Total Seal Piston Rings Mopar Oil Pan Gasket Set (includes rear main seal) Melling Oil Pump Eagle Specialty Forged Rods JE Stroker Pistons Engine must be bored to .040 oversized to achieve the 2.2 displacmentForged Stroker Crankshaft.
The head Kit Includes: * 16 Eaton PT Cruiser Lash Adjusters (Lifters)* 16 PT Cruiser Cam Followers (Rockers)* S.A. Gear Timing Belt* FelPro Complete Head Gasket Set* 1 Pair of Crane DOHC Cams 0016, or 0018* 1 Pair of Crane Adjustable Cam Gears* Crane Valve Springs
The odd ball stuff that I have pieced together to finish the motor is OBX FUEL RAIL, OBX PAN, AFX RACE ECU, OBX INTAKE MANIFOLD, AND THROTTLE BODY 55MM. I have a local shop that is going to build my complete turbo set up for my car. I still need to find out a couple of things. 1 will the afx race ecu work well with this set up. Or will I be better off going with dsm link..... what would be better for tunning? and the second i need to find out estamated hp and tq.... I'm planning on boosting 12-16. and the third is ### cam would be better Crane DOHC Cams 0016, or 0018. God If it was a old school v8 it would be easier.... that way i would know what injectors to get....

my bad also a walbro 255.

OK, I'll start;

Hmm......now you are talking about 420a, correct? DSMLink is for the 4g63. Will not work with the 420a. AFX ECU is too agressive and lean (in general) for a turbo set-up. The best tuner to get would be MSnS. Used by many (including me). I'm not a big fan of the Crane product for our cars. The Crane springs have been known to break and the Crane cams have a more aggressive ramp than the Crower's (the other cams that we generally use. Incidentally, I don't believe that they even make the 18's for our cars anymore. They may say for 420a but that would probably be for the Neon 420a (oops are you a Neon?))

Also, I missed whatever turbo you are using.

As for intake, the OBX is slightly better than stock (at least NA on the dyno it was), but a much better intake is sold by a gentleman on here called all_motor_mike (AMM). Very nice quality.

[MrMopar426]

Sorry not a neon. Avenger. my motor is 420A 97 eagle talon. the one I'm building is a 99 avenger 420A. only differnce is the sensor pluggins for the wiring harness.... were would i find these cams?

 

[MrMopar426]

and the intake manifold.... does it still have the spots for the factory pluggins?

 

[rstare]

You can probably find those Crower cams on the same site you got your stroker kit off of.
Crower - Camshafts - Engine - 95-99 Eclipse Non Turbo 420a - Mitsubishi - CI Motorsports

 

[MrMopar426]

as for the turbo.... Im not sure. This is my first with turbo. Im used to dealling with the older cars. What software does the MSnS ues.... The shop thats building the turbo kit is Inffant volecity motorsports (IVM). And they were mentioning a t3/t4....

What would be a good cam for this set up.... and still be street driven? The place i got the stroker kit had those crane cams...

 

[rstare]

Here's a thread for the intake manifold

[MrMopar426]

so besides the MSnS, and the cams this step withe the stage 2 crower cams. I still need to find out injector sizes?

 

[MrMopar426]

if you happen to know that thread to get it made pls let me know....

^^What's this refer to?

As for injectors, it will depend on many things. If you are getting MsnS 880's to 1000's would do fine. MSnS can adjust. If you go with a portfueler, then it will depend on your turbo etc. If you go just a S-FMU etc that will be a different set-up. Also need to look at what you are going to do for a fuel system. Yes, you have the 255, but what are you doing with your lines? FPR? Fuel rail is OBX; how does that mate up to your fuel ines? -6an both sides? -8an in and -6an out?

Just a few of the questions.

im open for suggestions.... but the MSnS is the only way i'm seeing. as for the fuel rail. the stock one has only 1 line in and my buddies has one in and a return line. Any ideas ?Im not one to only do half at a time. oh good point almost fogot about those... bare with me. this is my first deep build. I used to buy crate engines. but now i want more.

the guy who made the intake manifold!

 

[rstare]

You will have to PM him. AMM (All Motor Mike) he can hook you up. (For the intake manifold)
You say you only have one line going into the fuel rail. So I assume you have a 96' or later. You have what is refered to as the "returnless" fuel system. Their is a test port on the passenger side of the fuel rail. It has a schrader valve in it that you can remove and make yourself a return fuel line.

oh i see. thanks. now that i'm not going to get the head kit.... i have to hunt down those parts. and still havnt found the msns or a fuel regulator, and injectors. do you know of any decent head kits minuse the cams?

so knowing this it. and upgrading the fuel rail would mean i would have to run a return line?

what are the rules when dealing with fuel lines.... how much hard steel line has to be their.... or could briaded steel line work for it?

You can find MS at DIYAutoTune.com Megasquirt Kits / Assembled Engine Management Systems, Wideband o2 Sensor Systems and tuning products

Catalog Index - at RS-Autosport.com - Real EFI for Real People on Real Budgets

Products - SymTech Laboratories: Design, consulting, prototyping, and manufacturing - Megasquirt - FCD's - Manifold Spacers

When using MS you need a 1:1 afpr; like this Aeromotive 1:1 Universal Fuel Pressure Regulator - Aeromotive - Fuel Pressure Regulators - Fuel/Intake - Integra 1990-2001 - Acura - CI Motorsports

Not sure if your looking to buy a head that is pre built or just get a kit and build your head. But here is a link for prebuilt heads, w/o cams Staged Heads - Engine - 95-99 Eclipse Non Turbo 420a - Mitsubishi - CI Motorsports

I would run a return fuel line whether you upgrade your fuel rail or not. Yes, you can use SS braided line.

thanks. after looking at those kits. i though it was going to be more of a pain. so those work with the stock ecu?

 

[rstare]

By those I assume you mean MS. MS can be used as a piggyback (where the stock ecu still controls fuctions such as fans) or as a full standalone (where you ditch the stock ecu and MS controls everything)

I want to ditch the stock ecu... so the MegaSquirt-II EMS System - SMD PCB3.57 will be enough?

 

[rstare]

If you talk to one of the guys at DIY Autotune they will get you exactly what you want/need. Ditching your stock ecu will also require you to control ignition. In order to do this you need modifications to the MS 1 board.
