Next Mods?

[Pichimo]

Hey there guys i've been a member since i first got my DSM about 10 months ago. so far i've spent a lot of time and money just getting her to start and understand her needs. So far my mods have been bolt ons and yea i'm kinda cheap haha. my current mods are BBP Headers, MSD Ignition coil, CAI, N1 Style Cat Back Exhaust system, Luk clutch kit, Front strut bar, Lowering springs, 17" Rims, Ralco Short shifter, and indigo gauge face cluster. items that a'rent on yet but have purchased: Equus 3 gauge combo (water temp, volt temp, oil press), Auto meter a/f ratio gauge (not wide band... i know =( sad face) Ingalls Rear or Front camber kit (cant remember which one was put on) and DNA Front Strut bar and Rear upper and lower strut bars. I was looking into getting a bigger throttle body, but really wasn't sure of what size to get with the stock intake manifold. I don't even know what size the stock TB is to begin with. Also does anyone know where to get Mitsubishi dress up accessories? i've been getting more and more attached to my DSM. i'm awaiting for your 420a NT knowledge guys! and......... Go........ Thanks guys.

DOOOO ITTTTT!

The jeep throtle body is great upgrade, also adding a light weight underdrive pully would be beneficial as well. If you did both of these mods you will see a nice change in throttle response.

If i had your car, I would agree with the TB/IM being the next step. Either got with the 60mm or the 55-57mm both are great and both pros and cons have been covered a lot if you search around. After you get one, just take the upper half of the IM off, and port the opening via dremel or other type of grindind tool you have to match. Also (depending on your states emission laws) finishing the exhaust would be good (test pipe or high flow cat)

The UDP is also a great mod as silver stated

im thinking of going for the 55MM TB. the jeep tb sounds like a great idea but id figure that this motor will crap out any year now haha. after its done im gonna swap it with the 4g63. also with the 55mm tb i wouldnt have to do any drilling or part changing. its not that i dont want to, i just dont have the time for that or else i would have bought a 4g63 and have it sitting in my barracks room haha. as for underdrive pulleys, is there a certain brand that you recommend? and what difference would a high flow cat or test pipe make on performance?

For underdrive pulleys i would recommend Unorthadox, or possibly AEM. I can't give you an exact number of HP you will gain from putting on a test pipe, but it would only be a couple HP, nothing major. As for putting in a 4G63 Engine when your 420a dies will be VERY difficult, the 420a bolts in totally different from the 4G63, so you won't be able to just "bolt in" the 4G63. non turbo spyders are the only ones that have the right mounting brackets and such to do this swap.

 

[Silver99OZ]

Unorthodox and AFX are the two best UDPs for our cars. As for the test pipe, I installed one a few months back and I did not notice hardly any difference. In my opinion its really not worth it. You get a CEL from the rear O2 sensor and the fumes smell really bad.

I love that smell

Test pipe is something that won't really be worth it unless you need to really open up your exhaust (IE- turbo setups). I'd also spare yourself the CEL and failed emissions.

 

[MunkyX69]

I'd start thinking about power more then looks. Look into head work. Get some PT cruiser lifters and rockers, and a nice set of valve springs. Also while your at it get a mild cam and a howell automotive ecu. All said and done you'll put down a few more hp and with a larger TB and some headers you shoud be good to go. Not just that, but you'll be able to rev your car out to 8k before rev limit kicks in with the new ecu and the cams would love the slighly advanced timing.

Porting the TB and intake mani, combined with some headers will shift the power curve of your car up a litte ie. you'd be producing more power in the higher rpm range. So that's why I'd go with the head work and ecu to help boost that power even more and get more use out of it since you can rev higher.

 

[Fotowntalon]

great i posted like a 3 paragraph thing last night and it didnt post.... ANYWAYS

AFX or unorthodox racing are the two udp's of choice. Most people prefer AFX but they are much harder to get a hold of. Some have had good luck with ebay udp's, others have had many belt shredding problems, up to you if you want to risk it.

For the 420a 4g63, if you really want a 4g63, just sell your car and buy a gsx/gst/tsi. The engine swap procedure is very expensive and difficult. Another option would be to have the 420a as the DD and the 4g63 as the weekend warrior/track car. Why do you think your car is dying? You may be surprised how durable the 420a engine really is.

For test pipe vs high flow cat, they are just synonyms, i think the high flows just have the outside shape of a cat so its more unrecognizable where a test pipe is just a pipe. Either way you will probably fail an emissions, so research your state laws, here in Ohio, we are very lax on emissions.

As for the test pipe, I installed one a few months back and I did not notice hardly any difference. In my opinion its really not worth it. You get a CEL from the rear O2 sensor and the fumes smell really bad.

It being worth it is really what ya mean. They shouldn't be more than $20-30, and that its super cheap for the amount of HP you will get. Trying to remember the magazine I read but It was test pipe vs cat was a gain of 1-2 hp. that's about $15 a HP, deffinentally some of the cheaper horsepower. Also make sure if you get a high flow cat that's its truly a high flow cat, not a gutted cat. A gutted cat vs a cat is a loss of 1-2 hp, so be careful. You may get a CEL, to some people that is annoying, although what i say to that is, if you don't want a CEL, then why the hell did you buy a DSM?

For the not matching of the IM then dont even bother upgrading the TB. The IM will have a choke point then because it will be smaller than the opening of the TB so worthless. To be honest it is very easy to match the IM, and if you dont feel like doing it you can buy one cheap from CI motorsports for cheap (although i didnt care for their work others have had good luck)55mm Intake Manifold Port Matching - CI Motorsports

Lastly (sorry for the novel) as Munky69 said, port work on the head is big hp gains. I would however recommend against his suggestions just on the point that 1) they are more expensive and 2) They are more serious. If you really decide you like your 420a (which i am not sure you do if you want the 4g63) than go for it, and even then you need to decide if you want to stay NA or go boost. That all can play a huge role in selecting different cams, the degree of headwork, and what kind of tuning device to use.

 

[MunkyX69]

Didn't mention anything about porting the head, figured the OP might be on a budget, and thought of things that could be done while the head was still on the block. No disrespect Fotown, just wanted to clear it up. Either way porting would be a step to take if you plan to build a 420a motor for some real boost, but that sounds like a ways off.

IMO buy a 1g gsx or gst and put down some real power. No emissions to worry about in 98% of America, and for under a grand you can have a car that can run great times at the track. 420a's take a lot of time and money to put down the same power, but that's what happens when you buy a dsm. Sticking N/A won't really get you much on the platform... unfortunetly.

 

[LD25Delta9]

Just for sake of argument, you can swap in an evo8 4g63 motor when the 420a konks out. You pretty much need the whole front clip for the swap, though. I'm with the rest of the guys on the other upgrades, too. +1 guys.

You should read the "4G63 OWNERS BE WARNED" thread. Shame on you, too, Fotown....you will anger zee men in zee black robes

 

[Carter_95RS]

But the evo swap is no walk in the park either, from all of the information i've read about it it dosent sit in exactly perfect, it will bolt up but the overall position of the motor is setting to close to one side....but this may not be correct...however, you can put an evo 8 4g63 in your 420a bodied eclipse/talon. Is this the wisest choice? probably not.

Anyway, if i were you i would look into the jeep tb, i did with some help from a good friend, and i love the response. Even if the 420a craps on you, they're easy to find a replacement.

 

[Tanro]

but id figure that this motor will crap out any year now haha.

Why dont you just save your money, or part out your performance parts, go back to stock, and sell your car, then pick up a gst or gsx instead modding a motor that is gonna crap out on you....

Seriously hate chumps that have no clue working on DSMs even if it is "just a 420a". Chumps in 420a cars make so many people think of my car as "just a ricer"

And just to be clear, I like the 420a engine, its a good engine for what it is. The dsm variant is pretty damn strong and reliable.

It is a bash against people who want to waste cash on modding their cars, instead of investing the money to fix there cars.

If you mod a broken or breaking car you basically spending money to ensure that your car fails on you. And that is just pure stupid

All of that being said, get the jeep TB and Some Unorthadox Racing Pulleys, maybe find a SMIM.

 

[Fotowntalon]

Look into head work

first off, i had just woke up, so i guess my brain just registered this as head porting, so sorry for the confusion, i re-read your post and understand what you are saying.

Secondly

You should read the "4G63 OWNERS BE WARNED" thread. Shame on you, too, Fotown....you will anger zee men in zee black robes

I know the rules delta, and hate it as well just as much as the next guy when someone comes in saying "4g63 d0odz!" but, the op already said he wanted a 4g63, and the subject had been covered many times of how expensive and difficult it can be to do a swap, so why not just save him the money and hassle and start with the car "he" wants.

 

[LD25Delta9]

I know, I know. I just haven't been on in a while and had to throw that in there. Still, all are good suggestions and useful info for various paths to follow.

I put under a grand into my 420a and currently put down more power than a stock 1g gsx/gst.

It's been explained a million times, but the 4g63 guys seem to never get it. This is what he has, this is what he wants to work on, he will most likely not be selling it for a gsx/gst.

 

[Aproductions]

for mods... a TB and intake manifold would be great.

for dressup parts, pm me and I can find anything you want.

 

[Tanro]

Probably not, but he said he wants a 4g63T and to be quite honest, he could sell his performance parts, return to stock, and then sell his car and find a turbo car for the money he has.

In my area the 420a cars go for nearly as much as the turbo variants.

 

[motorswapman]

The swap from a 420a to 4g63 is a pain in the a$$ I currently own a 95 gs with a 6bolt swap. There is alot of cutting and custom fab. work that must be done. The only reason I did it was this eclipse was my first car and it had a blown engine and I had a 91 tsi that was wrecked.

 

[Pichimo]

nah ive just been sitting on it a while, im deciding to stick with the 420a and keep it N/A. i met a 420a DSMer in my town and his N/A smoked his buddies GST. now that i have another car, i can do some major engine work on this girl. every time i switch between cars, i keep saying "Damn, so this is the power ive been missing" haha its always a great feeling! woot DSM Rocks! i wish that someone would make a DSM seatbelt style belt.
