Hi there,
Im not too good with turbos and im looking for a good fast spooling street turbo. I have a fully built 2.0 (9.6/1), 280 cams, and a supporting fuel system on 93 pump fuel. I have a pte 50 trim journal bearing but im affrade it wont make 600whp, but if it does, it wont last long. My engine builder keeps telling me that Holset turbos are slow spooling, but I have never experienced one. I have heard a lot of recommendations for the GT35r, but again, no experiences. Any thoughts would be greatly appreciated! Also, cost is a factor, so cheep is good! (which is why i was maybe thinking holset)
Thanks!
 
I'd ask him how many holset builds he has under his belt, and why he can't get the spool times all the amateurs over here at dsmtuners can :p
 
HX40 will get you where you want. Also a Borg Warner/Airwerks 83/75 (s360). Both way under a grand and very well built.
 
One thing to consider... Most 600+whp cars don't have fast spooling turbo's. The two usually don't go hand in hand. The quickest spoolup you're probably going to see is in the neighborhood of 5200-5600 rpm if you can live with that. Also, if you're set on pump you're going to need meth to get you to the 600 mark, reliably.
 
He hasnt worked with any holset setups, just a ton of GTxxR setups, and I can see why he sicks to the gt series. And I wont be running meth. We have everything planned out to get the power out of the engine, not relying on boost for power. were estimating 450whp at around 15psi on the 5057 pte. Was thinking abuut just running the 5057 till it blows up, and then upgrading, but my tax return is looking pretty good this year :) does anyone have any dyno sheets or something to show spool times on any of these recommended turbos? Also, whats up with all these holset differences?? HX 35, 40, 45, 6blade, 7, 8? What should i be looking for?
Thanks!
 
The Borg turbos are great turbo's that are very reliable and are very loud!!! I run a S259 ett and hit 560 at 30 psi on the dynameter. You can go with the larger Borgs to get there easier but sacrifice a little spool.

While that use to be the norm, things are changing. Look at the Garrett 3582HTA or the Forced Performance DSM82HTA if you want a "mitsu style" bolt-on housing that won't restrict power like all the other bolt on housings do. Both these turbo's will make 600whp & will see 20psi ~4500 depending on supporting mods. 3586HTA or DSM86HTA are also another slightly larger option. They will support even more power then the above mentioned turbo's with not much more lag. None of these turbo's are cheap though.
 
Fast spoolin and 600hp dont really go together. Im running a bolt on BW 256 also. Great spool and if you get ett puts you over 500 but under 600, definetly a great "street" turbo.
 
I understand that these turbos wont spool right away, but something around 5000-6000rpm would be nice. How do the GT35r's do on spool time?

Looks like the Holset HX40 is what im going to go with. these things are very cheep, and sounds like they are very durable. Anyone have any recommendations on what style i should buy? Im not sure if they come with different hot sides, or turbine/compressor wheels?
Thanks!

I was speaking in generalities within the price range the OP was looking to spend in. I realize there are turbos that will spool quicker than what I had said, but also realize that the OP isn't looking to drop $1600 on a turbo. Usually the cheaper turbo's that are capable of supporting horsepower in the 600 range are lacking in the spoolup area. I paid $1300 for my ball bearing 6262 and i'm seeing 35 psi by 5150 rpm in a .63 T3 housing. With turbo's you usually get what you pay for.:thumb:
 
Any ball bearing turbo will get you great spool time for the power, but they will be much more expensive. (honestly though it is definitely worth it) A GT35 or 40 will get you there in power but the cost is high. A big FP hybrid turbo could get you the spool and power you need (the HTA86 is also a great choice ). 600hp definitely limits you on turbo options and spool time is definitely not going to be the greatest.... unless you do something crazy like 99gstracer and make a compound turbo setup (insane power...insane spool)OMG
 
Considering the comparable Holsets and BWs seem to outspool their Garrett counterparts, I am not sure why it would matter whether or not the cartridge is BB or Journal
 
Why don't you want to run E85 with the 400,000 stations there are with in 10-15 miles of where you live? There is even a station in your city.

The only thing I can think of is how hard it is to start when it's too cold outside.
 
blew 2 blocks up on E85 because I didnt know the formula changes every 3 months. I dont know how to tune very well, and i cant afford to pay for tuning 3 times per year. so pump fuel it is. Also, it use to take me 20 min to start the car on E85 when it was 20* out. yepp... Thanks for the link to the holset FAQ!
 
Ive got a good friend of mine who just made some insane power on a PTE 6266 but ran out of fuel... He is running E85 but we are not sure what the turbos limits are as of yet...

If I was int your position id go with a BW or Holset as they are very durable but you have to rememberthat the Holset's are happy with alot of boost(as they are made for a diesel)

Make sure you do you research on this but either way you go you should be happy...

You did forget to mention if you were going for a "bolt on" turbo, T3/T4, Twin scroll?? As all of these will affect spool, power, and $$$
 
I will be using a BorgWarner T4 twin scroll S200SX. There is a guy on lancer register making 550whp with this setup. His 25psi comes in at 3800rpm with HKS 272s. This is with the 1.15 A/R housing. I will be using the 1.00 housing for a little quicker spool.

What cams are you running? I'd say Kelford 272's or 280's and 30psi would get you to 600whp. BorgWarner's love high boost.

Its gonna be tough to make 600 whp with an hx40 on straight pump. My hx40 sees 40psi by about 5200rpm or so. The hx40s are good but if you want to run high boost with any journal bearing turbo its not going to last long.
 
S259 in twin scroll T3.

My thoughts exactly. I ran an S258 in the .70 open T3 and made 479whp on straight pump and stock engine, saw 28psi by 5k. A friend's S362 setup with a JMF divided T3 mani and .85 hotside saw 35psi by 4800 and made 708whp on E85. Another friend's S362 with the .76 divided hotside sees 25psi under 4k, hasn't cranked it up yet though.
 
My vote is for either the Borg Warner S259 ETT or the Holset HX40 with the billet 6 blade wheel and the BEP T3 housing.
 
Ya which is why I swapped the 274's out for some fp2's as Graveyard even told me that their cams are meant for really high rpm power bands. Thing pulled hard up top but low-mid was not so good. New cams should move my power band back down and tuning will be better this time to help spool.
