help choosing a bigger turbo

[syclone]

Guys I need some help I have outgrown my evo316g with my new build
what turbo would you suggest for strip/drag With a liveable amount of lag.
I'm thinking 50 trim but not sure on how many configurations their are.

my mods so far
car: eclipse GSX all wheel
motor; 2.3 6 bolt eagle crank/rods
ported/polished heads with crower springs,
280 GSC cams
Slowboy header
FMIC
weisco pistons
DSMLink
750 injecters
walbro 220 fuel pump
PLX devise wideband
3 inch exhaust
etc. etc ect

thanks

What's your budget going to be? Do you want ball bearing or not (faster spool)?

 

[syclone]

my budget is around a thousand, thanks for the response.

 

[Steve93Talon]

On a 2.3, I wouldn't waste my time on a 50 trim. Something that flows 60-70 lb/min would still spool well and have alot more potential.

Well you won't get a ball bearing turbo for $1k new so you'd probably be looking at a journal bearing. I'm actually pulling my SCM6152e off the car because it was more of a drag turbo and I'm into road racing. Check my dyno numbers in my profile. It was decent for around town driving, spooled up at around 4100 rpm and would have been great for straight line speed. You could go that route or the GT3561 (non-bb) which will spool slightly faster. Both of these turbos can be had for $700-900 new. These are just a couple of options, there are several other flavors out there.

I see slowboy racing has a BB turbo 50 trim for 1025.00
so what is one step from a 50 trim anyway?

 

[GVR4592]

I think it's worth the extra expense to go with a ball bearing unit. They are more reliable than the journal bearing turbochargers, and the quicker spool between shifts is an added bonus.

I would check out the bolt on GT30R or the GT35R. Both should reach 20 psi before 4000rpms.

 

[syclone]

I kind of like the gt30R, 500 hp is my max goal. spool should be pretty good,
so my next question is which compressor cover, they offer 3, To4B, To4E and To4S,
what does this mean??? what turbos are comparable to this?

 

[DSM_Obsession]

look at the s200....its just an all around amazing turbo.
i'd be running that on mine had i not blown the motor

 

[syclone]

can't find a lot of info on the S200/S256 it seems not many people have tried it, as it was designed for volvo diesels, I've read a lot of vender hype, but not much from actual owners.

 

[gsxtacy]

For the price/performance potential....don't forget the SCM-6152e...or the 6176.


The price is nice on the 6152e also...

Those are different compressor covers. The TO4B is kind of small for the GT30 in my opinion, the TO4E is the more common cover, and the T04S is the large cover. I would go with the TO4E or the TO4S. Make sure you choose the correct wastegate configuration as well.

Actually, you can now purchase GT35R's for $1000-1100.

But they don't bolt on to our stock manifold, a new manifold, downpipe and external gate would put a huge dent in the budget.

The tiny little hot side on my SCM5031 has became a restriction for me up top... I cant imagine how much of a restriction it would be up top on a SCM6152

The price is enticing though, almost sucked me in...

If you go with the GT30R, ie the GT3076, go with the E cover & get the Garrett surge ported inlet (inlet is 4" outlet is 2") as this turbo spools quick for its size & you will probably run into surge issues without the surge ported inlet. On a stroker I would imagine you will spool that thing in evoIII on a 2.0L times. Personally I would go with something a little larger like the 3082 (or Forced performances 3065, just for reference, not in the same price ball park with all the required parts). This uses the same GT30 turbine wheel but slaps in a larger comp wheel & larger S cover. On the stroker you should be able to spool it by 4000 rpms & have the capeability to make 600hp if your goal changes in the future. If you want slightly cheeper I'd look at the GT3561, that dejontool has listed. Its a std thrust bearing but becasue of the newer GT wheels it spools up faster & I have seen some impresive dyno results with it.

Thanks guys this is some good poop
I am a little flexable on how much I can afford,
my only restriction is I need to stay with the factory mitsu flange as I already have
a slow boy racing header with external wastgate. and I cant afford to buy a different header.
thanks again

You'll want to run a 61mm at the minimum. I would also steer away from the bolt on SCM series as well as they'll cost you some power.
A 50 trim is way to small for a fully modded stroker.

 

[syclone]

Well Now I am leaning toward this (go with the GT30R, ie the GT3076, go with the E cover & get the Garrett surge ported inlet (inlet is 4" outlet is 2") as this turbo spools quick for its size & you will probably run into surge issues without the surge ported inlet)

sounds pretty good, should make power and I dont want ungodly boost lag.

I never post here so i dont have the post count up to reply to your post....stupid but whatever.
Anyways my name is wes and I also have a built 2.3 in my galant. I will suggest you contact Forced Performance by phone and talk about the FP3052. You said your hp goal was 500. If you go to their website and click on the 3052 it shows some dyno graphs on a 2.0 where the 3052 made 504hp and 429Torque. It did that on pump gas and 27 pounds. Now on a 2.3 that turbo will see full spool in the mid 3000's and hold that amount of power till maybe high 7000's? (When the power will drop off is the only thing i am unsure of.) But either way this would make an awesome street turbo setup. Pump gas 500hp for 4-5000 rpm in every gear!! thats crazy.
ok, well that was my suggestion. Good luck with whatever you choose and happy hunting.


any coments on this

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

The info is solid. Users results will always vary, remember.

QFT

At 23 psi, my 2.4 flows 55-56lb/min. Get an sc61 in a .63 t3 or a t61 in a .58 t4. They will spool a around 4k on the big motor, and provide a good amount of power. Plus they are reasoably inexpensive and rebuildable.
They are both overkill for a 500hp set up, but I'm not a fan of icking a comparessor that will be on the edge to meet your goals.

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.

A 50 trim is way to small for a fully modded stroker.

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

 

[1stGenRocks]

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.
