Ok well my 50 trim 63 ar ehx garrett finally kick the bucket and blew out the seals right before I was ready to get tuned.So now I'm in the market for a new turbo.My setup consistent of
Rebuilt stock lsvtec with arp rod bolts and head studs
Gsr head with gsr cams
Skunk2 intake and throttle body
Pre 1000cc injectors walbro fuel pump
Cast t3 revhard manifold tial wastegate
Greddy bov
3 inch straight pipe
4 bar map sensor

The purpose of this car is drag racing and weekend cruising. Was going to run 14 psi for my high boost. Goal is 350 whp on high boost and cruise on 10 psi when in town. Back to the questoin at hand this guy on cl has this brand new T4 garrett 60 1 58 ar ehx with a 3 inch v band for 500 (pretty sweet deal) I'm not worried about the price.These are my concerns

Its a T4 and I'm setup for t3( I know I can get a adapter but is gona hold me back or work properly)
How is it going to spool
Is the small ehx housing 58 ar gona hold me back
What's this turbo capable of down road when gett a built bottom end
Would I be better of with a new precisoin 60 trim T3 599 shipped

Thanks for the help guys

racebum

the turbo you want is the 5431e it uses the new cea wheel and flows 50lb/min all out of a 50 trim. it's 679 shipped but imo well worth 80 dollars over the standard lineup

that monster you're asking about isn't even a consideration on a honda

EF ridin 4 Life

I thought heard sumthing before about the 5431 having surge problems..? I could be confusing with something else but you think the 60 to 1 with smaller exhaust ar will make up for the spool diffrence..?

racebum

that's the 5431b, it's completely different. even that guys have gotten good results out of at lower boost. the 5431e uses the E case and a brand new billet inducer wheel

this is the one i'm talking about

how much power to you want to make? a 60-1 flows a little more but will also have more lag. that 5431e could create 300-400whp pretty easy

EF ridin 4 Life

I like how that one has the optoin for a 5 bolt cause that what my down pipe is. But I'm lookin to make 350 whp for now but I want some room to grow when I build a bottom end.
One of the reason I'm intersted in the garrett is its such great deal.

racebum

if you get it i'd resell it. it is a good deal for a beast provided it's not thrashed

as for what you run, i vote 5431e, we'll see what others say. i just am looking at is a mix of spool time and hp production. it will do both

i can't really think of any turbo that gives you both a snappy engine at 350whp and 600whp if you turn it up. you could probably try and run a variant of a garrett gt35r but even that won't have the early snap of that 5431e. you pretty much have to fit the compressor to your goal

here's what i mean, here's a 35r on a b18c, thing doesn't even really get going till past 6k

I made the original comment of the 5431 having surge issues. What I was referring to was their Cast model (which was a v1/v2 trim compressor wheel). The new 5431 is their redesigned billet (or CEA as they would have us call them) that does not have that issue according to test results.

for 350whp its a very nice setup over the larger versions. The only 60-1 combination I would have used is the silver surfer, which Garrett doesn't offer as a standard package.

EF ridin 4 Life

Shodan how do you feel about the t4 to t3 adpater...? I'm worried about it leaking cause can't relly weld it cause my manifold is cast. Also still wondering how these 60 1 is going to spool.58 ar housing is kinda unique to see on a t4 and you relly don't see many people running it. I appercite the help

TheShodan

If you still have a T3, Keep it, and don't eff with it. For your goals, there is no reason at all to get a T4 or T4 divided turbo at all, regardless of your "deal". you'd hate life with it anyway based upon the housing choice you found.

EF ridin 4 Life

ok well we rull out the "the deal" then.lol so still need a turbo.I would say my budget is around 600 -700.Im kinda stuck between the precision 60 trim 6031 or the 5431 that racebum was talking about or a garrett t3t4 57 trim or 60 all in t3. kinda worried about garrett though cause i dont know if i trust there seals(kinda hear lots storys about them leakin) and thats what just happened to my 50 trim.

EF ridin 4 Life

yeah i totally get what you mean...i drove in my buddys precision 6262 gsr and it was like boost off boost on.No in between area what so ever. I really did lilke the spool of my garrett 50 trim but sometimes i think i would gett better tractoin with bigger one(not the t4 though cause we have ruled that one out)

racebum

the flow of a 3431e and 5431e which are 57 and 50 trims according to precision are pretty close. the 3431e is rated at 545hp and the 5431e is 500hp. i doubt you could go wrong either way. the benefit of the 5431e is that light billet inducer wheel. both turbos use the t31 exhaust section and can be had in a .63ar

Metaphysical

ive been doing research and my whp goal is about the same as yours (around 350-400 whp). you should check out the precision 5857 turbo, after I looked into it I fell in love

EF ridin 4 Life

so the 3431e is a 50 trim..? and the 5431e is a 57 trim..? Man the 3431e is only 550 at speedfactory ! but it didnt say much about the specs..thanks for all the help man

EF ridin 4 Life

Ill look into it...the only hurter is the price lik 800 something..! But you know what I've learned my lesson that you can't cut corners doing a boost build...that's why I'm looking for new turbo cause I bought a used one and it failed on me.

racebum

backwards

the 3431e is a 57 trim and the 5431e is a 50 trim

the 3431e has been tried and trued on a LOT of cars. i know gringotegra made 440whp on a stock gsr bottom end with that turbo and e85

EF ridin 4 Life

Thats what i like to hear...im digging the 3431e and you cant beat the price and speedfactory has them in stock(so i can just pick it up i like see what im getting before spend my money) and its a little bigger then my 50 trim.

bigsnorlax

How exactly does the 5431e compare to the standard Garrett t04e 50 trim with stage 3 turbine? They are both 50 trims as you mentioned but are the wheels the same size? And does the billet wheel allow quicker response as you mention over the garret?

The Garrett was pretty much what i had chosen for my setup and seems to be a great match with a solid compressor map. Is there a compressor map for the 5431e somewhere?

hahaha. Everyone has their "seals" story. The truth is that 90% of the time the "seals" issue is based upon user error by not adequately mounting the turbocharger in the optimal position, and not paying attention to their particular oil pressure during installation. Rarely is it ever a "seal" issue from the manufacturer of either company. Precision ironically gets the same bad rap for "seals" as well. The true difference between the precision and the Garrett is the bearing structure internally, and not the piston ring on the turbine shaft that gets associated with a bad turbocharger. I would not get a 6031 if getting the Precision due the bad mismatch between turbine and compressor wheel (regardless of turbine housing used). The newer 5431 or 5857 would be a bit more manageable.

If getting a Garrett, the GT3255 Journal bearing and Surfer should work, though they are a little more expensive than the $600-$700 budget you're looking at.

Again, If $700 is about what you can pay, the 5557 or 5857 is my actual vote for Precision... GT3255B for Garrett.

EF ridin 4 Life

Ok I have to look into those...but what do think about the 3431e..? I've read lots great reviews on them

TheShodan

iTrader: (14)

If I thought it was the right application, I would have stated the 3431 as one of the options . ;-)

Metaphysical

yeah, bad to cut corners especially on the heart of your system. If I recall correct I saw someone with that turbo putting out mid to high 300's (whp) at around 10psi with nice torque and hp curves. Spool time is perfect on it, just enough lag but still very responsive early on in the R'sPM

edit: on a very conservative LS build (forgot to state which motor)

EF ridin 4 Life

Yeah I've reading up on 5857 and I'm really impressed. I didn't realize it was so close the gt30r. Which would have been my first choice but price is up there...I think I'm gona wait a week or two(gota save up a little more) to gett the 5857. But metaphysical are you thinking of getting the journal versoin or the bb...?

Shodan I was insantaly gonna ask you about your choice of not stating the 3431 but then I realized that it proably has to do with the design of the new billet wheels and spending 200 more and getting turbo that's alot more efficent at higher levels(I know not up to 500whp) but still spools good. I think the 5857 is gonna fit my setup good and even better when I build my bottom end. Thanks for the help man

No. Racebum has it close but confused. The 5431 is not the same 57 "trim" Garrett 75mm exducer that people are used to understanding of its size. It may indeed have a difference between inducer /exducer to create a 57 trim, but its not the same measurements or design at all.. The 3431 IS the same 75mm exducer as the 50 "trim" that people understand.

The numbers rating that Racebum is stating is based at the crankshaft and not at the wheels. Precision has always rated them that way. The reason why the 3431 50 "trim" is 500 dollars is because that is part of the lower priced phase out that Precision is performing on their old models. Once again, I recommend not going that route, despite its price, and get something a bit more robust for your future goals without sacrificing midrange power.

racebum

hang on
<--scratches head

the 3431e is a 57 trim and the 5431e is a 50 trim.

what i'm lost with in this last statement is:

a: where i messed up
b: isn't precision using that 70mm t31 exhaust exducer on both the 5431b and e and 3431e
