420a choice of performance parts

[95eclispe]

ok so im looking to add to my moneypit on my 420a not trying to boost my car right this second although it might be an option at a later time.(with that said please no saying trash your 420a and get a 4g63 i picked up a 420a because thats what i want to work with) heres what i have in it so far:
F1 fidanza stage 1 racing clutch
new polished and bored out intake manifold
eibach springs and coilovers
MSD coilpack and sparkplug wires with NGK sparkplugs
powdercoated valve cover
battery rerouted to the trunk for more room
Megan Racing headers with downpipe

get a ###### fuel pump since yours is probably gone anyways like the 225 walbro and fuellab adjustable fuel regulator then get a nice intake manifold for it you can check alot in the classifieds or i have a friend that may be able to get you parts too just let me know what you would like

also take out that cat way to much restriction and do a full exhaust your loosing power there too

[WES_393]

Intake, exhaust, and ignition are all you can really do. Without higher compression, higher revving, or boosting the engine, you truly won't get much out of it.

well i just took my stock manifold and bored it out so it does the same as any aftermarket one the fuelpump ill take care of this weekend and the exhaust it just has an aftermarket tip that came with the car i want to delete the cat but anything else i should do to it for more power? it has a CAI too but besides going the turbo route idk what else to do

if i replaced my cams from stock to something big what should i go with? and would it increase hp being that its not a turbo? i just dont wanna end up throwing a rod

[AK Maniak]

You dont need a new fuel pump. I would suggest a lightweight flywheel or a lightweight under drive pulley system.

[MHuddy1213]

he has a possible blown fuel pump thats why it was mainly suggested in the 1st place a posted in another thread we didnt want to cross threads

Oh my bad. I didn't see that. Well in that case I would just get an OEM replacement or a 190 so you don't need an afpr

[MHuddy1213]

lightweight flywheel would be a very good upgrade too and yes i agree 190 would be the easier and better way to go for his application

[LeeSD1]

Lightening up the weight at the crank can free up some torque like previously stated at light weight flywheel and clutch and maybe a under drive pulley too.

[AK Maniak]

There is only so much you can do without boosting it. If you really wanna stay NT and up the power you could up the compression ratio but if you're going to go that far you might as well boost it.

[LeeSD1]

You can always go high compression for a little more power then later on down the road boost it. With a good tune and high compression on low boost application you will make good power

[95eclispe]

ok so about the whole flywheel thing i have a facing clutch/flywheel already but with my car you cant buy the clutch disk and flywheel seperate like you can with turbo models i tried. its all one piece so its always going to be heavier than others but i have as light as you can go without going stage3 which is for boosted models

ok so how do i up the compression? i have a stock block so dont want to end up blowing it buy tuning it to where it cant handle just need more output is all im saying

[MHuddy1213]

are you looking for faster off the line with good pickup or more top speed?

True, but you can always convert to a non-modular clutch for the lightweight flywheel, granted, this is replacing an already replaced clutch. Up to you. I like the lightweight pulley. For Cams Crower 2's NA grind are good for boost or NA. A 2.5" catback would be nice for either (unless you plan on boosting very heavily) lightweight mods are good all around

No offense, but unless you have a 2011 5.0, spending the dollars on an N/A motor doesn't get you very far. I wouldn't spend the dough. Save it for a turbo setup or a beater 1g.

well see i can always upgrade ow and down the road just drop a turbo in and re-tune and im good so essentially i wouldnt be wasting my money

You would be wasting money if you want to boost it later beacuse most NA Mods wont work with a turbo. Headers, CAI, etc.. you would have to remove all that if you go turbo

To get higher compression you need new pistons / rebuild motor

[LeeSD1]

If you get a new clutch you can get the light weight flywheel and a separate clutch disc and pressure plate. And an underdrive pulley.
To up the compression you need 'high compression' pistons which means building the motor, but you will get some power out of the high compression. THEN if you decided to go boost later on, you can still add some boost to the build bottom end.
If you dont want to build anything then you can just get a 2.4L bottom end out a cloud car and the 2.4L will give you more torque. But theres custom work involved in doing a 2.4L swap

so i got a oem fuel pump and its running again. im going to go with a 190 though. im looking into cams but dont know what size to get or brand? kelford? crowers? i just ordered eagle rods and weisco pistons got a great deal off them from another forum and my arp studs just came in. should i go with a ecmlink? i want to tune the car since i feel im not getting the full power i should be getting out of my car from these add ons.

Pretty sure ecm doesn't make anything for the 420a. The 420a guys tune with something else that work alongside your ecu from my understanding

Correct, ecmtuning doesn't sell anything for the 420a cars. You will need a standalone ecu such as megasquirt or aem for the 420a.

[iugrad92turbo]

Maybe ecmtuning will one day make a tuning device for the those running a turbo on their 420s.

this would be nice since i plan on going the turbo route in the near future. I will look into some stand alones but never swapped to a stand alone and i hear you can damage them easily if you've never tuned before(like me)

[greengoblin2011]

You said you bored you intake, have you put on a bigger throttle body? If not alot of people on here are doing a Jeep throttle body swap. It ups the 52mm stock opening in the throttle body to 58,but can be bored to 60mm. Added bonus is it wouldn't be a waste, you can still use it when you Turbo. I'm planning on doing it myself. Aside from that, ditch the cat and add cat back. Those wont do much, but can be used even when you go Turbo.

[95eclispe]

if i just go with a turboback exhaust without having a turbo would that make a difference? just curious

[bluespunk]

There are only three major parts to an NA exhaust, the header, the cat, and the catback.

you want something like (catback) this with a test pipe (short pipe that replaces the cat): 95-99 MITSUBISHI ECLIPSE RS GS 2.0L NON-TURBO N/A N1 CATBACK EXHAUST | eBay

I couldn't find a test pipe that wasn't a 3 inch one. I'd stick with a 2.5 exhaust over 3 inch while you're NA or you are likely to actually lose some bottom end power. 2.5 is fine for a low boost application too.

The only other exhaust part you could buy with an NA is a header. If you're going turbo later, you won't be able to keep it, so I'd skip it unless you find a super cheap one or don't mind taking a loss on it.

What you really need to do is decide how much power you want to make and pick a path to get there. Setting goals early helps you put your build together right without buying things you won't use or don't need.

Like others have suggested, the Jeep throttle body, or one from modern performance would be a good upgrade you can keep. An unorthodox underdrive pulley would be another. Both are popular mods in the 420a world and both are said to provide good results. After that, you'll be looking at things like cams and cam gears, which get a lot more espensive, but you can still keep them after a adding a turbo. I would save those for when you are ready to go to a ecu you can tune, like megasquirt. You'll get more out of them at that point.

A short ram air intake won't make a huge difference and you'll lose it when you turbo, but they are cheap. I think I paid like $25 for an ebay pipe and threw a aem filter on it that I had laying around from another car. If I had to do it again, I'd just look for some junkyard intercooler pipe and throw the filter on that. You can always put the filter on the turbo later, so it's not a big deal to spend the money on a good filter. I would stay away from the full cold air intakes though. Most aren't worth the money and you have to worry about sucking up water if you go through a large puddle.

Hope that helps, -Jake

I have the test pipe replacing my cat and an obx header with a cat back exhaust. I did it all at once and noticed a difference with throttle response and the car seemed more peppy. Don't know 100% which part made the bigger difference since I did it all once, but made a difference and wasn't real expensive.

I pretty much upgraded everything you mentioned except throttle body and underdrive pulleys and my exhaust. my cam gears,headers intake are done already. i wanna get a ecu so i can start tuning it to get the most out of them.
