Do I Need A Bigger Turbo(power goals has changed)

[spadepro22]

I have a bastard 20g in a downfiring housing and my goal was to hit 350-400whp with more of my goal on the 350 side than the 400 with this (then)being a stocker internally and a dd on 93 pump. Now I'm getting wiseco/eagle comb, 272 kelfords, and springs/ ti retainers my goal is fore sure to hit 400whp on 93 pump gas only. From research it seems I'm going to need a bigger turbo.

What's the best turbo for my goals on only pump 93 with the best spool time for a dd. I'm about to send the 20g to Jusmx141 for inspection, so if I need to upgrade, now would be the time!

Stick with the 20g

 

[spadepro22]

Stick with the 20g

I really want to, but don't want to max it on a dd and still not hit 400. Maxing it meaning by running it at 25psi since thats suppose to be the sweet spot.

 

[Cdc1221]

I would say put it on, drive it, and if youre happy with it, keep it. If not, move on. Ive been reading alot on the hx35. Look up turboglenns hx35 build thread

 

[ExtremeTurboSystems]

I would go HY35 for your goals. little quicker spool then the HX35. you don't have to run a BEP housing so its cheaper and it will get you to your goals on pump pretty easy. or a precision 5558 would be another good option. In a bolt on .63AR housing as well. If you want a price on the precision turbo in a special black friday deal let me know.

The 5858 i have has seen 60lbs @ around 33psi. which would def get you to your goals. Im mixing 30% e85 in to get that as well. Its been good so far, but with PTE you never know. I would choose the holset anyday.

 

[bastarddsm]

If you decide on the HY, I'd defiantly get a SMIM. It would probably take about 20 25psi to get 400whp on 93 with the HY35. It should make that boost by about 35-3800 with your combo. The good news it that it would also pull all the way to 9k, making for a really wide and fun power band.

PM me if you wanna go that way, and I can help you piece together a setup.

Forced Performance Turbochargers: DSM Green XL

On the shelf ready to go will fit your existing intercooler setup, O2 Setup, and produce enough air to meet your requirements and be about the same spool as your 20G you have now. Got em on the shelf ready to fly!

I should've added a bolt on turbo to the FP manifold, don't know if the HY35 is or not. Unless I found something that fits my existing o2 setup and downpipe.

 

[ExtremeTurboSystems]

no bolt on option for the HY35. HX35/40 you can run the BEP .55AR housing but I personally don't think that is the most efficient/cost effective way to go when the housing costs $250 shipped and the HX35 is usually around $350-400 for a good used one.

 

[spadepro22]

If Im going to get there with a bolt on, is the HX35/bep or FP green the only way to go with external off the 02 recirculated? I don't know too much about the PTE, tell me more.

 

[bastarddsm]

If you don't have the ability or a friend who can fabricate some things for you, I'd definatly go for the FP Green.

Dang I don't. I have to drive 2hrs to let a shop that knows dsm's to work on the car.

 

[snooopy365]

I would try to get the power out of the 20g.
It is possible to get this kind of power and if it doesn't work get a new turbo.
But hey you allready own the 20g, so why not give it a try?

 

[AK Maniak]

The FP Green might be pushing it but you might as well go for the 76HTA (Green XL) since it is the same price IIRC. Should have no problem meeting your goal and you probably won't find another turbo that will spool as quickly that is a bolt on while still being able to flow nearly 60lbs/min.

 

[WES_393]

I think the part people are missing is the 20g is a Bastard 20g. You have taken a higher flowing compressor wheel and packed it into a 14b/16g turbo. They spool fast and don't cost much, but at the price of less flow overall. While your standard 20g is capable of 45 lbs/min, the smaller TD05H turbine/housing is going to limit the compressor. So while 400hp may be possible, it won't be a walk in the park.

Why not go with an HX35 in a BEP housing? An external wastegate on the O2 housing could be found for fairly cheap, which would make it a completely bolt-on affair.

Edit- from your profile picture, it looks like you already have an O2 housing EWG, which could be used again with a BEP HX35 housing.

This is exactly why I would keep the 20g.
Power is about tuning the car, so if you are not making 400hp, I would try to find the reason.
Slapping a big turbo on the car and getting 400hp yes it is any easy way. But getting the "old bastard" to produce 400hp is the way you feel proud.
Just my 2 cents...

I have ran the 20g and its is setup with the external wg pr recirculated o2. The airflow of the turbo just doesn't seem like its going to cut it on pump and maxed out on a dd can't be good right? The compressor housing is bigger than the TDO5H, its downfiring if that helps any. I guess you can call it a bushcur 20g, however you spell it. The xl green is what I was looking at, its rated for 54lb/min.

I've also been looking at the hx 35 in bep housing, but I have no way of fabrication up what it needs to run. The closest dsm shop is 2hrs away.

It is actually capable of 59/lb min. i spoke with Michael as i am in the same place as you. He assured it is possible on 93 pump. but it will all depend on the best airflow optimization and components(intake manifold,etc,etc.) . as well as proper cam selection. Here is what Michael sent me to my question of making 400hp on 93 pump on this turbo.

The turbo isn't the deciding factor when it comes to whether or not it'll make X amount of HP with Y fuel. Is it capable, absolutely as it's rated at 59LB a minute maximum, can you do it, sure with the right mods. So focus on high flowing parts that make it easy for your motor to take in the air being supplied which will drop IAT's and result in a cooler denser charge at a lower boost pressure.

 

[spadepro22]

I understand the better flow of a smim, but for 400whp it really wouldn't be needed would it? I going with kelford 272s so that is plenty there and I also have ets inteecooling setup with 2g maf.

I also have a 2G MAF and ETS core with 264's. The 272's by themselves won't be enough to get you to 400WHP. If you HAVE to run pump, a good intake manifold and exhaust manifold will be required for 400. 280's or 288's would also be a good idea.

The compressor cover may be bigger, but the turbine and hot side are still TD05H. The 20g compressor wheel was meant to run with a TD06 turbine/housing, so the hot side is still limiting the compressor. Your exhaust will be restricted before the compressor runs out of steam.

There's no fabrication needed if you go with the .55 BEP turbine housing and Punishment EWG O2 housing. There's a reason they call the BEP housing "bolt on", it will bolt to the stock manifold and whatever downpipe you have. An 4" intake pipe, correct oil feed/drain, and maybe an extra coupler and pipe to connect the intercooler piping to the turbo. Ta-da! You have a complete 450-500hp capable turbo that spools below 4K and will keep pulling past redline. All for cheaper than just an XL Green.

Not to talk down the FP Green, it would be a much better option if you want a true drop in replacement. The Holset would require more work, but that's why it's cheaper.

Kelford 272 should be plenty for 400whp, there profile is probably bigger than other 280s. Not arguing at all. Should the FP mani should be good right?

 

[WES_393]

^ 272's are way more than enough for 400hp. Same with the FP manifold. Many many people have made well over 500hp on both.

 

[e85_4g63]

My 2 cents (if you want to stay DSM housing)

FP manifold
FP Green XL with the 8cm housing
Tial 38mm MVS (Punishment Racing o2 housing)
FP intake pipe
DSMLink v3 setup on SD
FP2 cams

Ok, so I promote the isht outta FP stuff, but hey, when something works, people notice.
