Bigger cams get some 272 cams I prefere gsc s2 cams they make amazing power.For any dsm build you should get ecmlink, walbro 255 fuel pump, and 1000cc injectors if your staying on pump gas, along with a 3 inch turbo back exhaust to start off with tuning is everything.I recommend those stuff to save money and order for future all this items will run like stock with ecmlink if you got a good tuner.Save money do it right do it once.Ummm my bad are you non turbo? Well you cna get some cheap ebay headers, intake, and 2.5 inch exhaust.But all that money won't really make power I would mostly leave it stock and it will last alot better.

^he's a n/t.

IMO if you want to go turbo someday you might as well do a basic built head like what's offered by our vendors but on a n/t your not gonna find an extra 50hp in just the head and ignition.

Go with just a stock head and save the rest of your money for a future turbo conversion or a turbo car.

This is in the 420A section, but i would think most of it should still apply.

No 420a's in the 1g.

He has the 1.8L or the 2.0 n/t.

I guess I was falling asleep at work. I would save money and keep the 1.8 stock sure u can get header, intake, and exhaust but price to power is not worth it.

Agreed^.

If its the 1.8 4G37, just leave it stock. It makes 92hp.

Now the 2.0 n/t can be converted to turbo fairly easy with factory turbo goodies. I would do that before any head work. You will not gain anywhere near 50hp with head work on n/a 4cyl.

I did a turbo swap on my 1g, well worth it.

I'm well aware of that. Which is why i said i know it was posted in the 420A section but most of the info should still apply. That list is parts that would help accomplish the goal for an N/T period, not just the 420A.

We have this section for 1g NT:
1G N/T Tech - DSM Forums

Since its an NT, start by letting the engine breathe. Highflow air filter, get rid of that stock restrictive snorkel. Headers and back exhaust system, with a high flow cat.

Replacing the cams would not help, even stock 4g63T cams:

If you're animate about leaving it N/A, you could always shave some material off the block mating surface, and port the openings for flow too!

It's a 2.0 n/t btw. Don't want to go turbo if not necessary. Headers available. A quick search only found turbo headers. I'll look more. Thanks for replies. Also, I have to replace the head ###
ruined the valves. Can I upgrade cams/valves fir any significant increase?

Is there a glossary for all these acronyms(LTH, UDP, IDC etc.) around somewhere for newbs like myself? I can research terms and technology but acronyms are a bit more of a challenge. Thanks

Stock turbo heads and non-turbo heads are identical. Tim Zimmer has made over 835whp on a stock, unported 1G head- there's not much you're going to do to the head that will add 50hp on a non-turbo application.

Well it may help him actually if he switched to a 2g head. Even being non turbo would assume the higher velocity would help him anyway. The 420a has smaller ports as well. Also using the 2g turbo intake manifold. All this is in theory but I think that would be your biggest gains.

No 420a in the 1g that's the 2g the 4g63 came n/a iin the 1gs and had some good power to them stock and is a good base to start with

I understand that the 420a is in the 2g I was simply saying that using a 2g 4g63 head would benifit him also having the smaller ports. would likely increase the low end tq. Being an na have volume is not the best setup.

using the
4g63 na cams
2g head
2g intake manifold

for an N-A motor should provide a decent imporvement.

Any difference between the 1g and 2g 4g63 heads?

Also, suppose one day I decide to go turbo, maybe now would be best to just grab the turbo head. Ebay has one with gasket set from J&C enterprises for $400 including shipping.

And if I never go turbo, what... will I just end up with more low end torque and less higher end?

What's the difference 1g & 2g IM's?

Port size.

The smaller 2G ports would likely add torque to a non-turbo. My girlfriend's 1G non-turbo has a 2G head and it's an absolute torque monster.

Keep in mind torque and HP occur at two different ends of the RPM scale. If he's looking for more horsepower, I doubt he's going to find it in a 2G head.

Yes this is true but, on an n/a it's already difficult to increase hp so adding more tq through the powerband will be his best bet on making the car faster. And more fun to drive. Also looking at the desgin of the evo 3 intake manifold it some what similar to that of a type r integra so it is possible he would benefit from that also. But in no way the same degree that the 4g63t does.

So would going with the 1g turbo head work? Or would I have to buy a different IM with that head? I guess another way to ask that question is is the 1g turbo IM anything different than the N/T IM, because I'm thinking I'd like to go with the turbo head so I'll be ready for a future upgrade to turbo, but I'd need to know if my N/T IM is compatible.

The turbo and non turbo head are the same thing, so there is no upgrade there. You would be replacing something with the same exact part. The only thing different with the intake manifold is that the turbo intake has a spot for the bov to connect to and the n/t does not.
