Which turbo will be sufficient for consistent 11 second times? I've recently decided on a big 16g, but will that be big enough to run 11s with supporting mods and decent tuning? Remember, this is for a budget street car, so any one purchase over $1k is tough. A big 16g will run about $700-900, which is about $300-400 less than the larger alternatives.

Of course, I'll need lots of practice to run these times, but, I just want to make sure that it's possible before the money is spent.
 
Well the problem is "spools fast" and "nice top end" are relative. Some people think 4500rpm for full boost isn't bad and others want full boost by 3200rpm. The same goes for top end. Do you want big power over 6000 rpm or good midrange power? What kind of numbers are you aiming for? On race gas a lot or usually 93 pump? Also, how much do you want to spend?

The Evo3 16g is a definite upgrade over the 14b, but there are quite a few people here that upgraded FROM an Evo3 16g to something bigger..

I've you've got the money and you want to go bigger than the Evo3 16g, I'd pick the Forced Performance FP3052. (www.forcedperformance.net)
 
im looking at 93 octane, and i want top boost around 3200-4000. Ru talking about the small 16g evoiii? Cause i know evoiii has a Big 16g. Or you mean just the normal Evoiii16g. AHh confusing. Anyway i want to be pushing like 17psi daily driving. And i want it to pull hard. My 14b pulled like a mother and it even had nice top end. And if i was going to get the evoiii 16g would it bolt directly onto my 6bolt?
 
Sorry to jump in and ask a newbie question buuutt.... The turbo for my 95 GsT is pretty much gone. I'm thinking about getting a turbo rebuild or just a new turbo. Well my question is say I want to upgrade to say the EvoIII the one listed for $539, what upgrades should I do to my car first (its bone stock), also what else should I buy to be able to install it?

dope dope. wouldnt that take long as shit to spool up tho? Thats a big fuggin turbo!

I wouldn't call the Evo3 Big 16G a "big" turbo - look at spool comments here:

You'll need something like this:
http://linux.forcedperformance.net/...oduct_Code=NTDSMEVO3P3&Category_Code=DSM-TPkg
and a J-Pipe:
http://linux.forcedperformance.net/...reen=PROD&Store_Code=FP&Product_Code=INTJPIPE

Might as well upgrade to a better flowing exhaust manifold too:
http://linux.forcedperformance.net/...?Screen=PROD&Store_Code=FP&Product_Code=EMEVO

Since you're bone stock, there's a bunch you should do BEFORE the turbo:
http://www.dsmtuners.com/tuning-guide/2gturbo/
(intake, gauges, turbo-back exhaust, blow off valve, boost controller, fuel system)
 
with my mods, would i need a new intake manifold and shit? Or would i need to get a evoiii intake manifold. etc. and i would order the big 16g and it would directly bolt on to my 1st gen bolt motor? I wouldnt need to get a 2g conversion kit for the turbo? Or since its a 6bolt motor it will bolt directly to my engine right?

I know i keep asking the same questoins but, would i have t o get the full evoiii16g KIT? Like gasket set, turbo housing, etc? Or would it bolt right ON minus all these parts!?!?!
 
i got to order the turbo by the end of this week thats why i need to know a solid answer soon.
 
for the evo 3 16g you do not need a intake manifold, but since you have a six bolt i would recommend upgrading the exhaust manifold to a 2g and porting the sucker out(thats the budget choice) or just buy the evo 3 exhaust manifold(evo3mani ,this isn't necessary but highly recommended

id buy it from either FP(while its on sale) http://linux.forcedperformance.net/...uct_Code=NTDSMEVOB16G&Category_Code=DSM-Turbo

or slowboy(i bought mine from SBR and i am very satisfied)

Well dude read up at my first post on this thread to see my supporting mods. I wanted to see with the mods that i have if they could alone support the evo3 16g turbo. If not i was just going to go a smaller like a 14b. But people r telling me the evo316g is the best bang for the buck and a big porformance upgrade. I got fuel pump and gages etc. i would need a evo3 intake manifold even tho i have a 6bolt block?
 
SO with these MODS i can support evo3 big 16g ?
6bolt motor swap
greddy type-s bov
hks turbo timer
190 walboro fuel pump
injen intake
dsmlink
short shifted
act 2100
full cat back exhaust
eibach coilovers
o2 dump

Without using a different intake manifold? I can push like 16psi NO PROBLEM? :confused:
 
Make sure when you purchase your evo 3 turbo you don't buy one of the knock off brands. Believe it or not there is a evo 3 knock off. The companies import them from japan for like 180-200 a unit then sell them for the full price of a real Mitsubishi evo 3 16g. Here is a link that talks all about it. http://www.slowboyracing.com/evo3vsgt.htm
 
I was going to get it from forcedperformance. IT looks fuggin dope. So basically I have the mods that i really need on my car already.

The only part im confused is the intake manifold and the o2 housing. Can i use the stock 6bolts? Or if im getting the stock 6bolt made for me would it be better to right off the bat get a evo3 intake mani and evo3 o2 housing? Last Question!! :rolleyes: :rolleyes: :dsm:

Ok, the information has been linked to you already you just simply need to read the information posted. The 02 housing you can get with your downpipe whichever one you order from some companies slowboy racing sells the evo3 manifold ported for rather cheap. Also they sell the evo3 02 housing, listed here actually.
http://www.slowboyracing.com/shop.php?sid=&cat=20
For the manifold and
http://www.slowboyracing.com/shop.php?sid=&cat=589
For the o2 housing.

You WILL NOT need a intake manifold, I don't see a need for another 02 housing yet unless your buying a downpipe as well. If your going to use the stock 2g 02 housing just get it ported or pickup a evo3 02housing.

But YES it would be better to get an evo3 EXHAUST manifold and evo3 02 housing to go with your EVO3 16g. Then you would just need a downpipe.

Thank you
John

What size injectors are you guys running with the rs49? I'm guessing 750-770cc.

I ran 650cc's with my RS60T and they were plenty for 22/23 PSI. 650's would be fine for the RS49T/50 trim. You could go bigger with something like dsmlink but with safc or a MAFT 650's are the way to go. mark
PS: I stepped up to 750's for my Holset HX-35/40 and run 25/26psi, no problem.

The FP housings are too small for a 2.3. They dont flow nearly as well as 4bolt T3 housings. It is a nice housing on 2.0L street cars but not for 2.3's & 2.4's. (would you put a GT35R on your car with a .48 housing?) The FP housing is still a bolt on housing. It is the best of all the bolt on housings, but a bolt on regardless.

To dig up an old thread, there's no real evidence the FP housing flows "no where near as much" as a comporably sized 4 bolt Garrett. Neither have I seen any conclusing evidence that a 2.3L/2.4L "needs" any larger exhaust than a 2.0L. Maximum exhaust output is limited by the turbos compressor, not by the motor.

If you were to call Forced Performance, they would also tell you that the FP housing is not a .49 AR. Being as some people would say that repeating what a vendor tells you is "hearsay" I'd go ahead and call FP on the phone if you have any questions.

"Hey, I'm going to custom cast a new turbine housing, I'm going to use the best materials, fit it for V-band flanges, and cast my emblem into it, but I don't think I'll use a modern volute design, I think I'll slop something together. That's how we build a bolt-on turbo that is capable of puting 3 cars into the top 10 fastest, non-n2o DSM list."

all right i am going to either get the RS49 or RS60-1. what do you guys suggest? I want a turbo that will tear sh!t up on the road, from a roll bout 50 or so. since I am FWD I could care less about lag (I get no traction anyways). I would like an easy 400 whp without squeezing every last little bit out of the turbo. Think the RS49 will be enough? This is a daily driver and will have 93 oct. in it 99% of the time.
Those both sound like good choices if youre fwd and dont mind a little lag a 60-1, cams, and a good tune should be a pretty fun time
 
for 1. you should be making alot more than 300hp from an 18G, thats just awful.

2. if your going to do t3/t4 dont buy a damn mutt, those exhaust housings that bolt up to the stock manifold are a complete restriction. if you want to go t3/t4 go straight t3/t4, buy the manifold and all.

3. with the size of the turbo's you are wanting to run it would be a very good idea to run external.

4. if you do want something that you can still bolt up to your stock manifold, look at PROVEN turbos, such as FP GREEN, 20G, FP3052, ETC, go on over to dsmtimes.org and start looking at what turbo's are doing what.
 
Bolt on turbos work just fine. Internal wastegates on bigger turbos can cause more trouble than they're worth, even though they can be made to work with enough fussing. Really though, having used both, I'd just cough up the cash now for an external wastegate setup and be done with it.

For a daily driver car I'd look at the FP30 turbos, just for the cleanliness of the installation and the retention of the stock manifold/heatshield. The other bolt-on turbos work well, but putting the wastegate on the o2 housing is a tight fit.
