A few 60 trim Q's

[Malero5]

Ok here are the relavent mods on my car

Big FMIC
3 inch GM maf/MAFT
Dsm link
walboro 255
AFPR
750 FIC injectors
3 inch exhaust
DSM link

here is the motor
2g pistons/1g machined rods
arp studs all around
clevite bearings
new water pump oil pump
1mm oversized valves
SS valves
hks 264 cams
cam gears

I am putting in a 360 thrust bearin turbonetics t3 60 trim turbo in my car. We hella potered out a 2g manifold and made an adapter plate to fit up and we are custom making an o2 housing going straight onto the turbo.

Here are my quesitons....
I am looking to hit between 420-440 WHP (i think my motor can handle it decently). What kind of spool will I have? How much boost? What is a good controller (I have a ghetto blead off turbo controller) that is under 200 dollars. Am I safe to shift at around 7800-8k? I am FWD and im about to do all the suspension setup so traction wont be to big of a deal.
Do I need to upgrade my intake manifold if I do a custom elbow? If so is it ok just to bore it out some?

I was going with an evo III but this turbo fell into my hands for an awesome deal...it was on a 2g that crank walked. SO here I am with a huge turbo and i know my 750's arent going to cut it over 20 psi.

TYIA,
mike

A sub 20 dollar Joe P manual boost controller will hold your boost level just fine assuming you have a good wastegate setup. The expensive stuff is just bullshit. Hell my switchable boost controller was around 70 bucks, but you could make one for 10 if you read the tech articles.

The intake manifold will work fine. A smim will work better at higher rpm but the stocker will get you to the power levels you are shooting for with no issues.

The engine should be just fine for the 400+ power range. Mu only suggestion is to install a good set of valve springs before you start spinning it up to 8k rpm. Some will argue this part but I would rather be safe than sorry.

As far as spool time, that is really hard to tell. It all depends on which turbine housing and wheel you have. Guessing you have a .63 a/r and a stage 3 turbine, full spool should be somewhere around 4-4300 rpm at 22 psi.

The 750cc injectors will work fine with the 60 trim. I run 26psi daily on pump with my 60-1 and only have around 80%idc.

As far as an mbc is concerned, I love my trusty hallman es. It was the best $50 I spent.

Your whole setup is almost identical to mine and mine has been working great for the past few years so I dont see why yours wouldnt also.

Thanks for the info.... the valve springs are brand new. The whole blcok is alllll brand new with 5k miles on it. Even have a fresh set of lifters

 

[HartmanMS]

When he said he recommended new valve springs, he was referring to stiffer aftermarket springs, not just new OEM ones. They will keep you from floating valves with those big RPMs. You could probably get by without them, but it is definately better to be safe than sorry...especially with all that money already tied up in your baby.

Have a good one,

So do you have a T3 60 trim, or a TO4E 60 trim? You said you have a T3 and everybody is assuming you have the TO4E.

The question that should really be asked is is it a straight t3 or a t3/t4 variant? 3" exducer on the compressor wheel?

 

[Malero5]

its a straight t3

 

[drivemusicnow]

Ahhhhh...


Just for clarification as I've seen several people mistake the two.

"Straight" T3 typically means both a T3 Turbine housing and a T3 compressor. This turbo would not make 400hp.

A T3 turbine housing, mated to a T4 (T04E/S) is more common, and would be able to put you well above your goals if you so happened to chose.

a "straight t4" is a T4 turbine and a T4 compressor. This is a huge exhaust side for a 2.0 liter engine and would take forever to spool.

Bolt on Turbos are different, and should be treated as such. Typically in a "bolt on 60 trim" you'd have a PTE/SBR/whoever exhaust housing with an A/R similar to that of the offerings with a T3 hotside. They then use a T4 compressor housing.

Hopefully this will clear up some confusion.

Specifications needed to know about how your turbo will preform.
Which A/R T3 hotside did you get?
Which compressor housing is used?


I've heard of 60 trims doing spectacular things if used correctly. Your goals seem reasonable though. (assuming a T3/T4 60 trim)

 

[GVR4592]

That is exactly what I asked.

Now that we now it's a straight T3 then you should know it's equivalent to a 14b.

People typically get confused and call anything with a T3 exhaust flange "straight T3" when it really is a T3/T4.

for some reason newer DSMers have equated T3/T4 to being related to having a mitsu flange (or so it seems.)

 

[Malero5]

When I sat it down next to a evo III it was much bigger on the spool side. The hot side said t3 on it, but it uses the t3/t4 gasket. Everyhting on it is larger then the evo III... so there is no reason is should act like a 14b.

 

[GVR4592]

So basically you have no idea what turbo you have. There's no such thing as a T3/T4 gasket, it's either T3 or T4. Do you have pictures? Can you take some measurements.

Seriously, read between the lines.

He has a T3/T4 60 trim. I'm guessing from SBR or PTE.

We would need to know what the exhaust housing is (A/R) in order to be able to give you any real estimate on performance. But considering you already have the turbo, why don't you bolt it up and get it dyno tuned.

How can you tell where the turbo came from? What are the winning lotto numbers for next week?

No, you said to4e, which only refers to the compressor cover. You can get them in to4e, to4b, to4s, and t3 style.

Anyways, under the assumption that you know for sure that it is a 60 trim, measure the od of the inlet on the compressor side and the over all od on the compressor housing and that will designate whether it is a t3 or t3/t4.

Its a possibility that it was purchased at slowboy but no possible chance it came from pte. Quit reading between the lines because you are missing the posted information. He specifically stated it was a Turbonetics turbo and PTE doesnt sell them.

The T4 60 trim wheel is designated as the T04E 60 trim by Garrett and Turbonetics.

And according to turbonetics, my 60-1 is a to4b. Doesnt make sense that a higher flowing turbo is rated in a lower class, huh? I have to say that most 60-1's I have seen were used with either a to4e or to4s compressor covers. I dont think I have ever seen one with a to4b compressor cover. Which comes back to my original statement, the to4b, e, s all refer to the compressor housing, not the size of the turbo.

I know they don't refer to the size of the turbo. I am calling it what the manufacturer's call it, if you don't like that call them and ask them to change the name. Turbonetics has a T3 60 trim http://www.turboneticsinc.com/cm_t360.htm and a TO4E 60 trim http://www.turboneticsinc.com/cm_e60.htm Which comes back to my original statement ,
So do you have a T3 60 trim, or a TO4E 60 trim?

 

[Malero5]

ok I looked at it really closely and the tage said... part type: t3 on the compressor cover. TO be honest... its a .42 a/r and i am pretty damn sure it is a t3 compressor wheel now that i look at it. It is probably the low end on then.... Either way i dont want to put it in my car yet considering i traded it for an evo III and i can easily trade it back. We made an adapter plate for the 2nd gen manifold and he was gonna make the part to connect to my exhaust (o2 housing. How good is this turbo? It is slightly bigger then the evo..... We might be able to find a better t3 turbo for cheap with a better opcmpressor housing. I dunno.... im sad to find out it isnt a to4e Soemone grinded out the lable ont he compressor housing...so we dont know for sure.

 

[Malero5]

might be .48 or .42 on the A/R i dont remember

 

[GVR4592]

The Evo3 is a better turbo.
