Default I now need some serious help from the turbo masters

OK
So I have:
1.8l
99 head
stock cams
volvo valve springs. Good to 8K rpm
9:1 CR
JE pistons +1mm
Eagle rods
Lightened crank (-7lbs)
all ARP hardware
+1 mm valves both sides
mild blending of the bowls. removed any boogers and cast marks
Paul style intake manifold modification
BEGI Series 5
Externally gated 38mm Tial WG
3" custom downpipe
Electromotive TechIIIr
880 injectors
110 oct VP fuel

I may have forgotten some stuff..

Anyway, you all know what sport i participate in. Some may dislike it, but you should still be able to help me.

I need a turbo. T3 footprint.

I want it full spooled by 3500rpm. hopefully before. I need good response. Not peak power.
I need 260 wheel ftlbs. Whatever WHP that come with that. 270ftlbs will be my max and i dont really need over 300rwhp.
The turbo can be maxed at 300-330hp. I really just need that quick spool and good solid midrange for days.

pauls dyno looks just about perfect for me. I can get up to 22psi and not worry about the engine at all.

i was thinking the 2560r would be perfect, but I have a T3 footprint. So I then looked into Turbonetics T3 Super 60 with the stage 1 turbine and .48 hotside housing.

Please let me know your thoughts. I hope that all made sense. if not please ask questions. I am on and off throttle and obviously in and out of boost all over the place. Its like a tight rally course for throttle modulation.

thanks everyone
-Jeff

Jeff, I think a .48exh/.60comp Merkur/SVO t3 turbo will get you those numbers nicely on the cheap.

Thanks. I aklso thought that turbo would be a decent choice. I was then also considering the model with a bit bigger compressor wheel. The Super 60 style.

No one else has any input???

I get to full boost 14 PSI @ about 3800 RPM on a .60 AR T-3/4, but im on a totally stock 97 motor. Not sure if what it will change on a built motor. But if your racing on a track you should be above 4K RPM all the time right? So it would be at max boost and TQ. all the time. even with a super 60 sized comp.

Occasionally you can find them already upgraded on ebay slightly used for a decent price. Your input may be a bit limited on here as not many are familiar with t3's. I will be heading to the tear a part today or tomorrow and will see if there are any with .60 compressors, but they are not very common.

The word he's trying to avoid is drifting. You want the torque band as wide as possible so you can avoid downshifting mid-drift if it's a really long decreasing radius corner and you fall below 4000.

I'd definately go with the .48 hotside and either a ported or external wastegate.

If I were a closet homosexual scat queen power-bottom handballer(drifter) I'd change quite a few things. I'd run a gt2560 (or equivalent), 8.6:1 compression ratio for starters because I'm making 252wtq (275wtq on a dynojet) at 4000rpm with my ".86 tater." A tubular manifold would drop spool-age down to where you want it. Leave the crank alone, run pump gas, and don't jack with the head too much.

If mid-range is what you want, then you want my spark table. I'm no engineer, but no one is running a spark table like mine, nor are they making torque like my motor. Low comp is the ****. I think my motor with a different hot-side would be perfect for what you're doing.

I've been reading a lot on what the hot-side does to spool and I've left with more questions than answers. A smaller turbine housing doesn't always mean faster spool, and a more aggressive turbine wheel the same. You might have success with a smaller housing and the same wheel as me...that's a question for the engineers here.

Yeah I d r i f t

Right now I just spool up way to late. I am making 283 hp and 256 TQ on a Mustang Dyno

Thanks for the input guys. I appreciate it. i also think a GT 2560r is the ticket. I just need a t3 that is equivalent to it.

Default Update

After speaking with Turbonetics and running this by their engineers they decided their T3 super 60 with a stage three turbine wheel and a .48 Turbine housing.
I installed this and running 17psi instead of almost 18, I had 299 rwhp and 270 ftlbs.

great numbers. The problem is that the dyno plot is identical to the last one. They both suck.

So now, the tuner,and my machinist think that the cams are off because my head has been decked several times. They felt if I buy adjustable cam gears we can put the cams where they need to be and reach this peak boost level way before it is now..

Anyone have some input??

I see you have a 3" dp. Is the rest of the exhaust 3" too? If not; maybe that would help your spool.

BTW, I had the T3 super 60 myself and sold it for the same reasons you mention.

I'm running a T3/T4 chinacharger from ebay and ever since I built my engine I'm seeing full boost at 3,600 rpm.

What A/R is your turbine housing?

The super 60 is alot smaller than what I took off. Thats why we are all confused. So i think the cames are coming on at the wrong tine.

My exhaust is 3" all the way out, no muffler.

I had a t3/t4 china guy too. i was seeing 18.5psi at about 4500.

i really think my cams are off. This engine is built and has higher compression than before. along with the 3" down pipe.

if you want paul's, then the super 60 is perfect.

it's technically a 2860 with journal bearings. you can get them built with BBs but they are expensive.

you'll be limited to pauls output too, dont expect much more than 300-320rwhp

I've made fairly descent numbers with it on my stock 1.6L



whoops i just read your old post...you made the mistake of going with a stage III turbine, you need a stage I. and with a .48 A/R housing...im sure they gave you a .63.


what exhaust manifold?


Here's Markp's old Mustang dyno with a T3 Super 60 on his 1.8L:

Thanks Brain.

I do have the stage 3 wheel, but it is the .48 housing.
Oh, BEGI cast manifold, 3" DP and 3" all the way out
I also got the BB model. I need my car as competetive as possible this year. I was given my D1 invite. I am not going, but it made me realize i need to step my **** up.

SO is there no chance of this turbo being fully boosted by 3500 at 17psi+ ??

If not, I need to have them put a stage 1 wheel on there. I am fine with my power levels.270ftlbs and 299rwhp on a mustang is perfect for me and thats only 17 psi. SO I can go up in boost if need be for the tage 1 wheel..

My T3 60 trim fits your want list perfectly. Plus its cheap as hell in rebuilt form from Gpopshop.
I have the .48 turbine housing, I have peak boost by like 3100 (14psi) and thats with the BEGI cast S5 manifold, EBC, 3" downpipe and poor timing tuning.
