97 gsx w/16g vs. honda s2000 with intake, headers, exhaust

[newGSXguy]

Hey, everyone out there, i'm new to the tuner world, another fast and the furious watcher, haha. Well, to get to the point, i'm trying to decide whether or not to lay down some cash on a race coming up. My dad bought me a '97 eclipse gsx and since then, i've done a few mods, well, my mechanic has anyways. I added a 16g turbo kit with b/o valve and a greddy exhaust that he said would do the system good. I also had everything ported and polished, which is what he told me.

Is there any way that i can take on an s2000 with mugen intake, mugen headers and an invidia exhaust.?

Any help would be great, cause i don't want to get embarrassed in front of other people. Thanks guys.

Depends, i've never heard of a dyno or track time from an untuned, stock boost 16g. In order to get much power from that turbo (and you can), you'll be looking at bigger injectors, a bigger fuel pump, a tuning device (S-AFCII for example), a datalogger, etc..

You do have a boost gauge right? A real one. How about a good intake and filter? Is the 'exhaust' a cat-back or turbo-back? What psi are you running?

I wouldn't put money down on a race between two cars in which you don't know the power of either.

Whats the dif between cat back and turbo back? Is there a dif in look? Im sure their is

[newGSXguy]

Thanks for replying guys, and like i said, i'm just gettin into this stuff. It's a garret 16g, and i'm sure he put new injectors and AEM rails. It's a turbo back with no cat, and i've got a K&N filter. The only thing i've got related to boost is an APEXi boost controller that's mounted on my dash. I really need to know how to choose the boost levels. How much for racing, and how much for just regular driving? All i need is a little knowledge.

Well, i dont think you have a garrett 16g because garret doesnt make a 16g. You probably have the mitsubishi 16g. As far as tunning any info on boost controllers for your settup, your best bet is going to be to search through the forums or just read them every night for any relevant information you may need. Good luck on the s2000, but id wait if i were you.

[newGSXguy]

hey soyee, i just checked my car and the turbo says "turbonetics." my sheet with the work done says t3 after the turbo, what does that mean, and i'm almost positive the guy said something about a 16g, so how did i get that confused with garrett? The sheet also says some other random stuff with numbers and letters, and i don't know much about this stuff at all, that's why i'm trying to learn!

[JoeWagon]

Well it's probably not 'random' so let us know what it says. There happens to be another factor in turning the boost up, which is tuning. You will run alright, and probably pretty fast with all that, but to control the fuel you need an S-AFC or similar.

I didn't think Turbonetics sold MHI turbos, but sure. The 16g has a t3 hot side to bolt up to the stock exhaust manifold.

A turbo back exhaust is everything from the turbo, and back... as opposed to only replacing what's after the catalytic converter. Turbo back is better obviously.

Don't mess too much with the boost controller until you have a way of seeing the results. For reference, you can 20+ psi on a 16g, however, no tuning device or datalogger makes it so you don't know if it's helping or harming your car when you turn up the boost. I'd keep it at ~15psi or lower.

Oh yeah and there's only one fuel rail, so singular: AEM fuel rail.

If you talk to him more,
What size injectors?
What kind of BOV (blow off valve)
Which 16g? (you can look on the compressor cover for numbers too)

[newGSXguy]

Ok joe, it says 150L pump? -6an fuel rail ends, P/N 25-302 pressure regulator, AEM fuel rail P/N 25-130, and something about 660cc injectors with new o-rings. It also has stuff about other multiple adapters to. By the bov, says ssqv, and it also says something about a gd multi-plate clutch? Oh yeah, and what does 3" downpipe and 3" turboback mean?

[duckydsp]

Oh yeah, and what does 3" downpipe and 3" turboback mean?

3" downpipe = the downpipe runs from the engine to the exhaust and the 3" is the diameter

turboback = everything in the exhaust system was modified from the turbo back

i believe the 150l pump is stock but i could be wrong so dont hold it against me!

660cc injectors will be perfect for the 16g... how does the car run? like when you floor it, is it sluggish? like does it feel your getting too much fuel? cause i dont see a fuel controller in there it might run too rich with the 660's!

the HKS SSQV bov is pretty nice... i like it, i use it on my RST

3" downpipe and 3" turbo back is your exhaust... that is also a nice upgrade for your 16g...

and atleast you know you have an upgraded clutch... i have never head of GD tho...

[newGSXguy]

It does feel kinda sluggish on the hole, is that cause it's running too rich? Do you think i should get an APEXi AFC? If i need one, tell me, and i'll pick one up this weekend. Should i also check out a B&M short throw?

[JoeWagon]

It will feel sluggish until you start building boost, maybe around 3k. You need an AFC to tune with, so if you want to continue modifying your car, get one. You also need a datalogger, or you don't know what to tune by. Most people do the pocketlogger/s-afcII combo it seems.

B&M works, check out this thread http://www.dsmtuners.com/forums/show...=short+shifter

Good luck.

Damn this kid is loaded...car and eerything handed to him...i envy you :sad: ...at least hes doing some good performance mods, unlike some rich kids that just put on the rims, bodykit, huuuge win and stickers and call it a rocket :laugh:

[newGSXguy]

Thanks for the help guys, I called my mechanic and he said he could get me in tommorrow for the APEXi AFC and the short throw, and while i'm there, i'll get him set it up for me. Even though it prolly doesn't seem smart, i'm gonna race the s2000 anyways, and plus it's not like i'm racing the stakes (only $150). What the heck, I need to get experience sometime. I'll also check out that datalogger.

[JoeWagon]

Definately some confirmation on the fact that you have more money than you know what to do with. If you have your heart set on always having someone else do work for you, that's fine... but realize that 95% of DSM owners do their own work.

A normal mechanic doesn't know shit about an air/fuel controller, so make sure it's a tuner shop.
