help choosing a bigger turbo

[definitiveno]

I dont know if this is better to post in here or in a new thread but here goes

I dont have a horsepower goal but i want to retain streetability but not drop off up top like my 16g.

right now i have a big 16g. im looking to do cams and a bigger turbo. i was looking at bolt on 50 trims but a friend of mine can get me a freshly rebuilt gt35r with a o2 mounted tial 35 and a bolt on precsion housing for 1100. what kind of spool up time and power am i looking at with this turbo on a 2.0 with MLS hg and stock 1g pistons.

what would you guys recomend for my setup? its mostly just a daily driver seeing some autox but mostly drag racing.

Thats a trick question, a gt35r can not be rebuilt and what is the A/R on the turbine housing? 1100 is not a terrible steal, how many miles on it?

I agree that the Mitsu turbine housing will probably cost you a little bit of power but he's already said he wants to go with a Mitsu housing. So the SCM would be right up his alley.

Depends on whether you're drag racing or road racing/autocrossing

Hmmmm, mine flows 55-56lb/min on pump gas(23psi) with a 1-2% decrepency from boost and Boost est and 70* inatke temps. If you weren't chasing a power number and had to no desire to crank the boost on c16 then I guess you're right.
A stroker and 35r ish turbo would be just fine for road racing and even good for auto-x with the smaller gt30 turbine a la fp3065.

You can get journal bearing GT35's, so some can be rebuilt. You can buy journal bearing GT35's with a 1.18a/r turbine housing new from ATP for under $1000.

I just assumed since he said gt35r that he meant a gt35r, not gt35.

Those dyno numbers on the 3052 on FP's site were on a 2.3.

How do you know that? From what i have heard from other members is it was a 2.0 motor not a 2.3.

And i believe some one made 520whp on a 2.0 on pump gas with that turbo as well.

thanks for the insight. i sent him a message asking what all was redone and what ar it is.

I believe both cars in question, black98's and FP's shop car both made that power on 2.3's. I don't remember exactly but black98 had dsmlink and FP's shop car had a full stand alone and a rediculous head (stage 4 package or some thing, not sure) on it.

Your 2nd hand info. or sources are obviously useless. Both cars were 2.3's.

ok he got back to me it is a gt32 with a gt40 compressor wheel. .63 AR non bb. with an E cover.

 

[brute]

The FP 3065 is a GT30 turbine wheel and GT40 compressor wheel, but is ballbearing. It seems like with a turbo that size they'd want to run an S cover or something larger than the E.

Absolutely an S cover is ideal, also 1100 for non ball bearing unit is unreasonable. Ive seen used fp30's go for less than that on the boards here.

 

[1stGenRocks]

1100 is for the turbo and the custom o2 mounted tial 35 with dumptube and stuff to bolt up to my downpipe

 

[definitiveno]

You have a t3 or mitsu manifold?

 

[1stGenRocks]

mitsu. the turbo also has a bolt on mitsu housing made by precision

Turbo shouldn't be more than 8-900 dollars
wastegate 200
O2 housing with waste gate flange 250-300


total: 1250-1400 bucks


Guess it's an okay deal. I would offer him a grand and see if he takes that.

If you want to make big power, you're better off doing it with a turbo a little bigger than you plan on. Why? Stressing the hell out of your turbo to make power will shorten its life significantly.

I wanted 500HP+ but didnt want to worry about heat under the hood, going too fast (yes, with a fast spooling turbo its hard to resist) on the street and turbo replacement. I ended up going with a T4 SC63. Yes, I've got ALL the supporting mods. No, the list in my profile is quite dated.

I had a local fab up a manifold for me, and I'm getting spool at 4k rpms. Its nice and smooth and easy to control on the street. I dont go fast unless I put the hammer down and I'm in control of what speeds the car gets. It fit my driving style perfectly. If this thing ever lets loose I'll be getting a T4 T67 to replace it, but I'm happy with it for now.

It made 400HP at the wheels at 18 psi a little while ago on the dyno on pump gas. I'm now running 25 psi on pump and I can tell you it scoots. For that little extra oomph I've got an 80 shot of nitrous for the track.

Why am I posting this? Go big, dont look back. Worst comes to worst, with a garrett setup you can just plug and play with the turbo options until you find what you like. Its possible to take a T3 T67 and get the right housings on it and it'll spool pretty well for a street turbo, but have a top end far beyond what you'd expect.

^ Totally agreed.

I just wanted to illustrate the size comparison between the EVO III 16g GT and my new pte SCM-6152e...and I cannot see a reason that says this turbo will disappoint in any way.

IMO a 50 trim variant, or 60-1, or even a 6152 is a great 2nd turbo (with full supporting mods in place already of course)

I opted for the SCM-6152e because:

1. Bolt on
2. Notorious for big power
3. my heat sheilds will still fit (with some modification)
4. I like my car to look clean and simple.

Let your research and your desires/intuition guide you.

 

[syclone]

well I am really leaning toward a fp3052, because,,

it will bolt up to a mitu manifold
it will make 500 hp
it will spool quickly with a 2.3

anyone know if I can use my evo 3 o2 housing, or do I have to get the v-band setup.
also my header has the wastgate mount on the # 1 runner so I wont need the external wastegate.
last who has the best prices on FP turbos, thanks

James Sanders

 

[nanokpsi]

You have to use the v-band stuff with the fp turbine housing.

 

[gsxtacy]

and btw, the 6152e is $500 cheaper to set up and does everything on your list....I am done here.

 

[syclone]

Well I've been reserching the 6152,
the negative sides are
slow spool, 4100
I've read alot about the SCM (sport compact mitsubishi) lots of threads saying they are restrictive.
it is not ball bearing.

on the positive side it looks like it will make 630 horsepower

I think the 3052 is a better suited to my needs.
now to find a way to buy a cheaper v-clamp/wastegate, any ideas?

[XakEp]

SC6376 T4 w/ .81 A/R and S cover, 3" discharge. 400HP at 17 psi. On pump. Boost at 4500 rpms.

35 psi? Oh yeah.

 

[definitiveno]

The spool seems unrealistic for that size housing, not calling you a liar, just saying.........


Have any logs? I notice you have dsmlink......

I'm on a 2.4L not a 2L. It really does make a difference.
