Car is all stock I'm in the process of replacing the water pump and gas tank. The car has 200k miles on it. I was looking to do a few mod's. I'm only looking to spend about 600 top's on this car I will be doing all the work myself and tuning. Witch leads to my question what the best cheapest way to tune these car's and keep them kinda reliable. SAFC 2?

Thing's I'm looking to buy.

Used Evo3 16g
Injectors? unless I can use my 2g tsi ones they are 450's correct what's stock in the 4g61 380's?
SAFC 2
Evo 8 FMIC core.

I have a whole 2g talon so I will be using some part's of that for the colt such as the manifold and o2 housing. MAF and w/e else you guy's think I can use.



Thanks guy's hope to get some good info from you's. And maybe some used part's :)
Using an S'AFC is gonna be the cheapest way to tune it. I'd recommend investing a wideband, but that will put you over your budget. 450cc injectors are way too small for 250-300whp, I'd recommend at least 660cc's. The stock 4g61t size is 390cc. An EVO 8 FMIC will work well. A 2g/3g/EVO MAF will also work well, you won't want to attempt this on the stock MAF or even a 1g MAF. Make sure you upgrade the fuel pump too, a walbro 255 or something like that. You'll need to run race gas and a lot of boost to make that kind of power, but it's possible.

What can I make with pump gas? how much boost would be safe? 20-22psi? If I need to I'd remove the meth kit from my sti for the colt. Also would a stock sti fuel pump work ok? I replaced mine with a walbro 255.


The widband on the dyno should be enough.

I have no idea what you can make on pump gas, but there aren't a whole lot of people making that kind of power with a 16g without at least having upgraded cams. Race gas would just make it a lot easier. Meth would help too. I don't know what a stock STi pump can flow, I wouldn't waste my time with it.

I might throw in a 2g exhaust cam. think that may help?

I read here somewhere that people do this. Also they use the 4g67 head on this block from what I read as it has bigger ports and the same cc chambers.

There is word that replacing the exhaust cam of a 4g61t with one from a 4g63t and then retarding the cam gear one tooth will cause the turbo to spoil quicker and the motor to flow the exhaust a little better. I was going to do this but blew my motor before I got around to it so I couldn't tell you first hand, but by talking to others it sounds like there is not much of a difference. The 1.8l head is said to be a good upgrade so that would probably be a good investment.

I didn't realize this car still had a 4g61t in it. In that case, that may be an upgrade, but I've always heard that 1g cams were better than 2g cams. Either way, I doubt it's going to be a night and day difference.

1G manual cams are the ones you want.

Ok looking back threw what I have read it was a 1g 4g63t exhaust cam. I probably won't go threw all that as I'm sure a 16g will spool plenty fast enough for me. I daily my sti with a 35r that's pretty laggy. but if you drive it right it can stay in boost perfectly.

Anyone know what intake manifold would be best to use? out of all the stock ones that is. I'm looking to keep this a budget ride. Unless I hit the lottery lol. Then I may get an Evo to add to the collection. wishful thinkin I know. :(

If you're gonna go with a larger-port head run a cyclone intake manifold and hook it up properly.

There are different cams for manual 1gs. It depends on year and I believe the 93-94 is the best one to get, but I could be wrong. Plus just because the car is a certain year doesn't mean it has the cam it's supposed to. To be certain you must research your cams markings, letters, to determine the profile of that cam. There is a list somewhere out there of all the different cams that came in DSMs and what profile the markings stand for. This is why some people do cam swaps and don't feel a difference while others do.

The differences between these cams are seriously barely even noticeable. I've always heard that 91+ cams are slightly more aggressive than '90 cams, but I think it's a DSM urban myth more than anything.

Maybe someone said it to sell some used cam's laying around. lol. No that I'm looking I'm thinking of going with a PTE 5031 turbo what you guy's think about that turbo?
