420A HP Increase?

[1999eclipsers]

Is it possible to bring the HP up to 200 horses with bolt ons alone? If you look @ my cars profile you will see what I have done so far. It has only 46k on it and is well taken care of.

So back to the orignal question of getting 200 hp with out getting into the engine? What are your thoughts? This is my goal for this car.

 

[Epic904]

You could do a turbo or nitrous to obtain this. If you want to do it N/A you'll probably have to increase the compression ratio and do head work. I may be wrong about this though so it may be possible.

 

[murray1]

You will need a lot more then just bolt ons to hit 200 hp.

Look up bulletdsms profile. He has the fastest/highest hp NA dsm on here. He has a built engine, MSnS computer, bolt ons, porting etc. and he is only making 176 WHP(give or take a couple just going off my head).

With just bolt ons you might hit 130-140 whp. Probably only around 170 HP at the crank.

 

[tegster1]

A turbo is the only way you will be able to raise your hp that high without touching the engine. You wouldnt be able to run high boost on a stock engine but you wouldnt need to either with the goal you have.

Nitrous and n/a would both require upgrading your internals and doing engine work to reach your goal.

Take a look at the parts catalog on here in the upper left to see the turbo kits if you want. They are not your only options but just something to look into.

The juice is good noooo?

Sorry SNL skit. Anyway a zex type kit will be perfect for you. A 75 shot wet kit will get you to 200 and be safe on a stock engine too.

Well so far I have a Injen short jam cold air intake, Greddy DT Muffler, IX Irdium plugs, and Accel 300+ thrundersport wires. I waiting to do a exhaust header, high flow cat, and a ecm flashing. What might I see in power numbers from this alone? And if I did nitrious what might the numbers be then? Lastly what seems to be the prefered parts for my future upgrades?

You're probably not even at 140whp. There's no way you can reflash our ECU's, so I'd drop that from the list. Add a 75 shot of nitrous and you'll be around 200whp.

Do a compression and leak down test first. You need to see what kind of condition your motor is in *before* upgrading.

Just boost it. It's the best bang for your buck.

 

[1999eclipsers]

Well I know that my motor is in top condition it doesn't have any oil leaks, no dark exhaust smoke at all, and it has a power takeoff like a bat out of hell and thats just with its current mods. I'm trying to keep this car in a sleeper appearance so the kids around here might think it stock until I blow their doors off if they think that their beater has balls.

So it sounds like nos might be the direction to go. Don't get me wrong I'm not into street racing but I do like to push some good back country driving.

Yeah with 200whp you should be able to make the NA guys look pretty dumb but don't get to crazy and start challenging wrx's and evo's or anything . Your wallet and patience is the biggest factor in nitrous or turbo decision. Turbo charging a 420a is not hard and is very doable with good stock motor but it's the odds and ends that make it a somewhat pricey build to do right. Like engine management and cooling. While you don't anything really crazy with 6psi and a small basic turbo reaching your hp goal will be a little harder. Most stage 2 systems will put you in the 200-225whp range which require a fmic 12:1 fmu and other little goodies that can add up quick. Nitrous is real easy and contrary to popular belief safe. Especially with a wet kit. If you think that your car performs fine now with what you have I honestly think a turbo is overkill as with a full exhaust and one of the intakes like mark(bullet) makes your car will wake up and be perfect for you with a 75 shot in the wings for any local ricer you might come across


Not to start a debate but nitrous is the bang for your buck. That's universal in both import and the domestic world. A $350 nitrous kit can be pilled with the right jets to add 150hp show me a $350 turbo no less kit that can do that. People say you have to refill all the time but keep in mind with a stock car with all bolt ons and nitrous you can run 93 when your gonna spray with a turbo you have to run it all the time. Next time you get gas see how much more 93 is and factor that into your daily routine.

 

[murray1]

The problem with nitrous is that it is illegal to have filled in your car unless you are at a track.

Your best bet is to go with a turbo kit IF your engine is in good shape.

If your compression is bad or engine is worn out then you are going to be looking at a rebuild and then turbo kit or do a slight upgrade from stock. Neither of these options are going to be "cheap" and will require you to do the work yourself unless you are willing to get hosed on labor.

What I would do, turbo kit if engine is in good shape, or do pretty much stock rebuild if that will satisfy your needs or drive the car till it breaks(or sell it) and pick up a different project car that has some better potential.

Well if I were u I would just save my money and purchase a turbo kit from HAHNs, an you will be better off then trying to do all of these small up grades & spending more money than you'r going 2 need

The Hahn 420a kit has earned it's reputation. I bought one 6 months ago for for my 99GS for $2k and installed it in one full day w/o any other mods to vehicle. I have some mechanical experience, but it turned out easier then I would have imagined. I have also learned more about this vehicle in the last 6 months then I had the 1st 8 years of owning it after the decision to turbo it... With your set up, a stage I will get you to 200whp and stage II 250whp easily...

Either you have a diffrent idea than I do about easily or you have a diffrent idea of what a stage 2 kit consist of. Not to mention you 2k is a pretty penny.

 

[TreDay]

I just put on underdive pulley to my 420a and I know that I am not close to 200hp but I was very impressed with it. I am not reaching for the stars with my 420a but try small basic things and make it even more fun to drive, 200hp on bolt on seems very hard if not impossible.

 

[1999eclipsers]

Well gentalmen it seems that there a number of ways that I can go with my power intentions for this car. Maybe a wet nos kit will be the direction I'll go. For the reason I want it still be able to run on 87 with a octane booster or on higher with out having to stay in the high level range. Although I also have the ability to buy racing grade fuels in 5 gallon buckets from my work if needed.

I understand that installing nos is on the easy side other than the mounting of the bottle.

Mounting the bottle is the easy part but you have your options and some info to go on. Turbo kits are sweet they are pretty much the engine equalizer but 2k kits and turbo headaches are not for everyone.

 

[1999eclipsers]

So what about the flow control for nos (aka the on off control switch)? Can you turn it off or do you have to close the valve on the bottle?

Back to an old Question from earlier about peoples prefered (cost effective) headers? what brands have some of you tried and whats the common chose? Is there a difference between 4-2-1 and 4-1 header types?

Well they make progressive nitrous controllers which gradually induce nitrous into the intake stream. You really need to read up on nitrous in dept before getting into it to prevent damage to your cap via improper use. 4-2-1 headers are better mid range headers and 4-1 are better up top headers that's the rule of thumb. To be honest it's not worth it to go 4-2-1 as they are harder to find and almost always more expensive.

 

[murray1]

I am in the process of ordering a Tsudo header. Supposedly its a 4-2-1 design. I am getting it for a pretty good deal of ebay, header + N1 catback for 320 shipped. When I get it I will tell you what I think of it and might post pictures if I can borrow someones camera.

N/A stock block 4 cylinders will aways be slow. you gotta boost it or fill it with juice to stay with the big dogs. period
not to mention if you are like almost all the KIDs on the forums once you go fast you'll wanna go FASTER. you'll find yourself saying this "75 shot is sweet, c'mon lets throw the 150 or even 175 jet in there i got off EBAY"

We're not ricers cough cough honda guys we're dsm owners. Not to mention that is what this site is for to help people avoid stuff like that. By the way I was once a tsi guy so I know how a manual boost controller can be just like nitrous pills.

wow its hard to believe how some dsm owners can be as ignorant as honduh owners and we're "KIDS" because we choose to modify a 420? id love to see you line up to bulletdsm at the track and see what your almighty turbo can do and btw next time READ THE RULES! before posting ignorant turbos better then non turbo comments

 

[2Nyce_Talon]

One of the first mods i did to mine was the 420a Bolt on Kit and a 75 SHot. Had it tuned and timed but about 3 weeks after having it all done i decided to see how far i could push it and it fried my stock pistons (well mainly one piston) but after i locked that up i bent all the valve stems.
Alot of people say the 75 shot is safe but it didnt do to good on my stock motor the frist time around

 

[99RedGs]

2k isn't that much.. If you think 2k is alot to spend on modding a car you need a new hobby.

As far as I know bullet is the only respected n/a 420A I have seen, and he has a lot of time, effort, and money into his car. Not to mention some bad ass driving skills. I would say if you just want a little more power to impress your lady friend once in a while a 75 wet shot is probably what you want. ( you'll also need the supporting mods for that such as a bottle heater, window switch, etc.. which adds up also)

I say this because it seems to me the turbos that come in the kits aren't as efficient at the low boost you can only put on the stock 420A. If your going to get a turbo kit, you might as well build the motor so you can take advantage of it

That is just my .02, and by the way I have seen stock block type-s' in the 13's which is fairly respectable for a 4cyl n/a stock block.
