Turbo upgrade advice

[Srt4RacerDave]

Knowing that I will need larger injectors and a new way to manage fuel, I am looking for advice on a turbo upgrade. I want my car to get low 12's high 11's in the 1/4 with little problem. I also want something that will bolt onto the stock manifold and can have the option to be internally waste gated. I was looking at a Mitsu 20g and the FP Red. I don't want to get something too big, but I'd rather have a big turbo and not use it's full capacity then a smaller turbo that needs to be maxed out to get the results I want. I have Crower 272/272 cams so I would like a turbo that can take advantage of them. The 20g is in my price range but I'm afraid I'm not going to get that much more out of it over my current 16g. Thanks in advanced.

Checking to see if your car has an EPROM ECU is as simple as pulling the cover and taking a look:

Unless the cover has been swapped, you can often tell by simply looking at the part number on the cover....there will be a "E" in the lower right hand corner of the label:

Again, the best way to tell is to pull the ECU and have a look. You can't trust that the cover is the original unless you bought the car when it was new.


I think what SiNiST3R was referring to was similar to what I was describing....that DSMLink will allow you to get the most out of your current setup via timing and airflow corrections before you jump up to the bigger turbo. Think of it as Link allowing you to use a 16G at 95% of it's potential instead of a an AFC using a 20G at 65% of it's potential to yeild the same power output.

Link's launch control alone will shave seconds off your E.T. just by giving you the advantage of not having to worry about launching consistently every time.

You can tool around with DSMLink by just downloading the program and scrolling through the preloaded runs. It's free to download, and you can learn alot about what it can do for you without ever hooking it to a car. The program and user guides are downloadable here: DSMLink - Downloads

Keep in mind DSMLink is currently in the middle of upgrading their entire program to a new version, which will look nothing like the version you'll download. However, you can still get an idea of how the program works.

Just to add some food for thought. I ran a tdo5 20g on 25 psi with FIC 650s and an afc. My best pass was 11.76 @ 118.5. I was on race gas too. I have an EWG which doesn't make much difference and I also use a 2g MAF, just so you get an idea of the setup.

I think DSMLink is a very good idea too. I upgraded about a year and a half ago and haven't done much with the car since. The nice thing about DSMLink is that it can run almost as well as a well tuned afc with very little work.

Right after I got it I set my global and deadtime for my 650 injectors and ran a 12.20 on 20 psi. Race gas again so I didn't have to worry about timing. The car has since been 12.0 with a bad misfire.

ECMLink/DSMLink v3 is about $600.

Used Hx35 in a bolton bep housing as already mentioned. BEP bolton turbine housing and turbo can be had for the same price as your 16g was new. You can sell your 16g to buy the hx35 and only have to come up with the money for the turbine housing. Bolts on. You only need to worry about oil lines no water lines. Spools as fast as your current turbo, is journal bearing so is rebuildable for under $150, and flows enough up top for 500whp. Many have gone into the LOW 11s with it. It will easily reach your goal, you'll have room to grow, and you will sacrifice zero "streetability" vs. your current setup.

Save the difference in cost between the hx35 and the fp3052 and buy and eprom ecu and dsmlink . Besides the hx35 has a better looking compressor map than the fp3052/gt3076r.

After that post last night I spent two hours snooping around the DSLink forums and page. Still reading the user guide and instructions though. How long did it take you guys to learn to use it to it's full power? Some of the things it can do I've had no previous experience with tuning before. I'm going to check on my ECU later tonight. But to get the original post back on topic, I think I know someone who uses a Hx35 but it is poorly tuned. You say it's good for that much HP? That's impressive.

494whp, HX35 at 25psi, bolton housing, 2.0L with boltons
11.2sec @ 126mpg, HX35 at 28psi, bolton housing, stock manifolds, 2.0L with 272s

The fp3052 is impressive for a bolton built by a reputable company. I know of one GVR4 who trapped 131mph with almost full weight. But the vast majority won't see more than 500ish whp with one. And it spools about 500rpms later.
