450-500whp, pump gas, s256?, pte6262?, or 5857?

[ZenkaiRacerDsM]

Yep its another one of these threads, sorry. Stuff just starts boggling my mind when I look at all the turbo options and start reading posts that produce even more options. Also most of the threads I get in the search resutls are a little older and the newer more efficient compressors aren't being considered in them.

The turbo will be going on my 97 GST. Its not my DD, but I will be taking out on the street occasionally. So lag isn't too big of a deal. I would like the turbo to be capable of 450-500whp on pump gas. So it needs to be efficient and not working too hard. I also want to keep with a dsm turbine housing since I don't want to dump my expensive punishment MVS setup and I already have a FP manifold. I know this isn't the best choice performance wise, but price wise it is.

The turbo's I listed are ones that I'm looking at on extremepsi. I don't know where to look for bigger s200 series borgs. If you have better suggestions please feel free to input. The PTE's I'm considering are the journal bearing units. But skeptacle on the center section reliability.

Ultimately I want over 500whp on pump with nitrous. Yes nitrous will be installed as well. I have a kit just sitting collecting dust.

As for my mods I have RC 1000cc's, 255hp, link v3, Fuel lab FPR, ETS FMIC, FP mani, PR MVS wastegate setup, 3in catback, FP 18g turbo, ACT 2600pp, w comp clutch carbon/kevlar disc.

I will be purchasing a built trans with lsd, a built head for my FP2 cams, and wheels w/slicks around the same time as the turbo purchase. And I will be building a block myself in my spare time. This will be on the stock 7 bolt bottom end till it blows. Its a mitsu remanufactured shortblock with about 30k on it.

Thanks for the input!

I would suggest staying away from PTE turbos, too many of them fail. My best friend has a 6262 on his spyder, made 521whp with it, but the kicker is that he has had it warranted 4 times so far for it blowing up and it is almost out right now. PTE won't replace it this time and he is out on his own now. PTE turbo's are known for blowing on dsm's. I would suggest that you look into one of the revised FP Green's or Red's. They have the HTA compressor wheel now, and will easily get you to your goal while being able to keep your mani and o2 housing.

 

[hubz91talontsi]

Never had a problem with my 6152... great turbo, loved all the whistle. But if youre looking for only 450-500 just get a 20g.

 

[unisonicz]

20g would be about maxed @ 450 would it not? I am asking as more of a questions than a statement.

 

[hubz91talontsi]

No... Curt Brown made 499 on a fp16hta68... He could make 500 on the 18g he has now.

To be honest if i were you i would just get a Curt Brown cylinder head with the kelford 272s, With that head i dont see why you couldnt make 500 with the turbo you have. A little spray wouldnt hurt .

 

[bastarddsm]

Your going to need a pretty big turbo, at least 55lb/min, probably 60. You make about 9whp per lb/min on pump gas. If you to E85, you can make 500whp on a really cheap bolt on hx35. Or a s256. or 30R

 

[hubz91talontsi]

No he wont need a big turbo, stop feeding people that bullshit.

 

[bastarddsm]

Haa. Find me 10 examples of sub 44lb/min turbo's making 500whp on 93 oct pump gas without water/meth injection.

It can be done, but unless you are an allstar tuner, your not gonna do it.

 

[hubz91talontsi]

Well lets see, he has 1000cc injectors so why run pump. He also stated WITH nitrous. and a built head... I made 324 with a stock sidemount with my 14b with e85.
I made 410fwhp with a 6152 at only 17psi on pump with a junk front mount and evo8-9 maf with dsmlinkv2.

He can easily make 500.

Well i guess i am an allstar tuner then...

 

[E116]

If I was you I would get an s256. It should get you 450whp pretty easily. And just because Curt Brown can make 500whp with a 16g sized turbo, doesn't mean most people can.

 

[BrokenTsi]

I made 490whp at 20psi on a mustang dyno with a BW S366.

I've also ran this turbo in FWD mode on my car. Its perfect for a FWD car.

Yeah i know but im tired of hearing "it will max it" its garbage. I got 31lb/min out of my 14b on a stock sidemount.

 

[johnmarines]

Never had a problem with my 6152...

same hear.... I'm not sure if its because I'm running it t3 or not.

 

[rock1t]

why not rock a holset hx40? cheaper than anything else anyone has listed. the holset spools faster than that of others. very reliable, and if you do blow it up, the rebuild kit is cheap. like $80 cheap.

was his turbo a Journal bearing or BB?

 

[Steve93Talon]

I made 479whp on my S258 in the .70 T3 hotside on 93 octane. Stock 6 bolt bottom end/head/intake mani, FP2 cams, V2, 2G MAF, full 3".

Anyone who's saying a 16G, HTA68, or 20g type turbo can hit those kinds of numbers on pump, using someone like Curt as an example, needs to realize the money that setups like Curt's have in parts that 99.9% of people would never put money. Like über-high compression built engines, properly ported heads, aluminum driveshafts, electric water pumps, and countless other tricks that add up to significant horsepower gains over the typical setups with the same turbo.

 

[ZenkaiRacerDsM]

The S366 sounds like where its at, but I dont believe it can be had in a dsm housing can it?

My 18g will be on the edge of its efficiency range to get the numbers I want on race gas, let alone pump wont it?

Edit: I just saw that theres more posts. Those numbers on the s258 look great! I wonder how much power a dsm housing will choke off though.

Where can I even find a s258? They're not listed on extremepsi's site.

I wouldnt run a bolt on housing even if you could with this turbo. Does it have to be a bolt on housing? 500whp on pump will be alot easier with a T3 setup IMO.

 

[crash89]

He did say he wants to stay with the DSM turbine housing however, I agree with BrokenTsi on that it would be easier and more efficient to run a T3 housing.

 

[ZenkaiRacerDsM]

I just already have a FP manifold and SS Punishment MVS O2 housing. I guess I could sell them though.

I really am not aware of how much the dsm turbine housing sucks. But from what I'm gathering it will be well worth the extra money to change my setup. Any recommendations on T3 manifolds? I still have my main stock radiator fan in place.

I just had a thought though. With the added price of a T3 manifold why don't I just get a FP DSM HTA3586R? 3065, or 3052? Thats along the lines of what I wanted in the first place before I thought to cheap out and go with a dsm housing so I wouldn't have to sell anything off.

No... Curt Brown made 499 on a fp16hta68... He could make 500 on the 18g he has now.

Please stop spurting your bullshit.

Curt brown made 499 on a normal 16G, he never got to the dyno with the 68hta. He doesn't have an 18G.

OP - your goal on pump gas will need a pretty big turbo to do easily. I'd say new green, 5857 or bigger from pte.

 

[dsm-onster]

Yeah i know but im tired of hearing "it will max it" its garbage. I got 31lb/min out of my 14b on a stock sidemount.

Yes, talk about shYte flinging. the 14b flows an easy 34lb/min. and who cares about the stock sidemount. we all know it flows rather well. cant cool for nothing, but flows alright.

the bolton hx40 has seen your goal, and backed by track results to insure. No hella high compression build with zero reciprocating mass, plus "secrets", etc. The record for the 16g, and and td05h hotside is about the value of the rest of the build, not about the simplicity of using what mitsu engineers gave you for great power. Why cant commom folk accept and understand that the record is not a ruler for the posterity of the product???

 

[JusMX141]

450-500 with a good tune = Holset HX35, BW/Bullseye S259. Check the Holset results thread, or check out the thread on Wendy's car to see that it can be done.

450-500 fairly easily = Holset HX40, PTE 6262. Again check the Holset results thread, and if you choose the journal-bearing version of the PTE 6262 you may want to buy three or four of them.

 

[bsbllfit7]

this is a good thread i think, i have similar goals and have been thinking hx40 as of lately, i might modify my goals and shoot for around a hundred which then id ###### go 20g on e85 or an hx35. Keep bringing the good info guys

To be fair though, Wendy's car was on E85, and most if not all of the 500+whp results you'll find in the Holset thread - or anywhere else for that matter - are on race gas or alcohol.

The pump gas stipulation is really the stumbling point here. Hitting the numbers on straight pump is going to require alot of supporting mods that are well matched. Doing it in a bolt-on housing is extremely difficult, even with the FP bolt-on hotside.
