Combination Advice w/ Holset for street

[98spyderboost]

OK. I'm planning my motor setup based on a few solid factors here they are.

1. I have a semi new HX-35 (MUST USE )
2. DSMLink (of course )
3. Full Interior, I am slowly burrowing through the compartment under the drop top housing for extra room.
4. Stock bottom end. (at least for this specific project scope. Maybe a 6 bolt in a few years, but not yet.)
5. Here is the hardest part, thank god for DSM Link My wife drives the car a lot in the summer.
6. My end goal is a very efficient 350whp without NOS (before uprgrading bottom ends) With the ability to be tuned down to allow for more civilized driving like in the city(or my wife). Say 230whp. And be just as smooth as possible at both settings.

My question??? Take a look at my outline at the link below and fill in the blanks. Please constructively as possible. For the purpose of this post I really am concerned with the engine mods to support the hx-35 under the goals I am wanting to obtain.


This is the current plan I have for the entire project. Evolving over the next two years. Not in any way limited by order of this outline! Each Heading will have a link to all the info I have collected on the subject and my own walkthrough if available. I'm about 50% done with just the outline. I have a few more things to add. Gunna put some rice mods on there and of course my engine build-up. I would hope some of you would help with the supporting mods and bolt ons kinda stuff. Keep in mind, the things listed above are static, the rest of the outline of the link below, well, I can bend some on

http://home.comcast.net/~spyderboost/myproject/projectoutline.htm

The site isnt anywhere near completion. Hope to have the rest of the site functional this week. It will change dramatically over the next week as a matter of fact so keep an eye on it.

first of all that is one huge turbo. a lot of guys use that on a TOTALLY built stroker motor. that would include, complete bottom end, head work, cams etc etc. also that turbo can easily make way more power than you really want. so your goal should be relatively easy. i am sure you have looked at the tuning guides on this site. they are a great outline for upgrades, and i would say with all of them included, along with that turbo. you will have a very nice, quick, and fun car

Well my reasoning for the turbo is simple. I have the unit already. And it does flow ALOT. And it will basically be the last (kind of)turbo I buy cause I will never want that car at more power than it can handle. But it should be possible with DSM link and a good boost controller to "put it in econo mode" and be pushing around 14lbs of boost. Or am I just being hopeful. If it's possible, this is the info I am looking for.

I eventually want to use a holset hx40. I purchased a e16g as my first turbo upgrade though(I thought my 14b was dead). There are way to many supporting mods needed to run the holsets the way I would want it

Personally since you have dsmlink already, I would get fueling mods done, and then install the holset.

 

[sweet97]

WOW! I'm fretting over my upcoming Walbro 255HP install! ! Recommend the Walbro also. I run a Cold Air Intake now that I have a couple of pics of except I use webtv so I would have to email them. I run an AGP RS49-50 trim. Found a 3" polished aluminum intake for a mid '90's *HONDA* at the local Advance Auto store. Trimmed a few inches from one end and now my filter is sitting in place of the original sidemount IC as I have a FMIC. Since I have 2 cars and my driving situation is flexible I have the filter exposed, water is not an issue. I love it!
The rest of your project is over my head! I run 660cc inj's. Don't know what the Holset flows but I would imagine 720's would do. Good luck and keep us informed as it's an ambitious project and will be interesting to follow! Good Luck! Mark

What kind of wastegate do you plan to run? Big turbo on low boost needs a big external wastegate.

Might as well go with the MAF Translator too.

He doesn't need a huge external wastegate to run that amount of boost, he can use the 38mm internal wastegate option for that turbo and should be fine runnning that low of boost.

This is what I was planning for it. So you think it's possible to run the boost that low on that unit?

Dont know about the wastegate yet but like on my outline, the MAFT setup is in the werkz already.

98spyderboost: 14psi? You're retarded.

Any tuner knows that with DSMLink you can tune what injectors you have and deadtime for them. So why the hell are you gettin an MAFT? :thumbdown

For only 350whp you have a huge turbo and loads of lag, your wife will not have fun driving it when she has to downshift two gears when she wants to pass someone.

 

[TurboGeoff]

dsm10sec is ABSOLUTELY correct, the hx35 is wayy too big for what you want to do, it will slow you down more than make you fast. Id suggest a 20g or 50 trim to do that job, the hx35 is a giant turbo and not very streetable, you would not easily be able to drive in traffic with it and mild accell would suck.

Also, you cannot run 14psi on that big of a turbo, the minimum i think was 19 on the wastegate you get from bullseye(i think).

On another note, i wouldnt even think about putting an hx35 on a stock 7 bolt, maybe a early 6 bolt, but id definately build the motor first.

Remember, you must learn to walk before you can run, its all in the baby steps my friend.
Start out small, and upgrade to bigger and better things, thats how we do it in the DSM world.

What the hell are you talking about?

External wastegates are sized by the turbo size, not by the amount of boost being run.

good call!! most people running holset's have either built 6 bolts, or strokers and they are fully built street cars, with upwards of 450-500hp running over 20psi daily. those are serious turbos, that would be like trying to run 14psi on a 3065. good luck with your setup man!

He is building a car full of gizmos and computers. Why leave out the MAFT?

You are wrong about the wastegate. You need to consider the boost level you intend to run along with the size of the turbo. From FP's website:
External wastegates are generally mounted to the exhaust manifold or to the O2 housing, and are self contained units. External wastegates have the ability to bypass large amounts of air, and can provide steady boost control at any pressure level. A common myth is that in order to run higher boost pressures, you need a larger wastegate. This is incorrect. Larger wastegates are necessary to run low boost levels on large turbos.

14 psi on this big ass turbo will be far out of its efficiency. Driving the streets with a car that won't spool until 4k rpm will suck. Your wife will hate you

The real question is, why must you use this turbo?

Well I already have it the only thing I will need is a bullseye kit.
That makes sense about that external wastegate. Oh and she may drive it but it aint her ride She says it has enough power already We know that aint right!
Oh and you are correct about the gizmo part. But in a subtle way of course.

Bullseye DIY Kit $309
Selling the hx-35 ~$500
Selling the MAFT that you have NO NEED FOR ~$200
$1009

et a BR20g, faster spool, and can still get 130mph+ traps.

BTW, either way you go you're going to need huge injectors and a good fuel pump. If you end up using the MAFT you will get wild timing with it. Sell it!

Ya, hx35 can do what, 140 traps?

OK there seems to be some confusion. Let me clarify. I plan on doing the project based on the POTENTIAL the holeset has. I want everything to be able to handle that unit when I do put it on.
Engine internals arent the focus of this thread. Supporting mods for the holset is. For instance, say I have my dsmlink installed. I want to upgrade my big fuel rail, my big pump, my huge injectors, coils, & wires. Can I not put the mods on to support the holset without actually bolting on the holset yet? What are the largest sizes for any equipment I can use and still tune the car down to around 250-300whp at for "wife/vallet" mode.

The largest sizes for equipment? You're pretty stupid when it comes to cars aren't you?

The only 2 posts you make in this thread you verbally assault me like a 2nd grader.

Thanks to everyone else for their advice and continuing constructive criticism.
Thanks to dsm10sec for reminding me that evolution missed a few people.
BTW dsm10sec, I wont mind if you just stop posting in this thread. I promise!

 

[98spyderboost]

Anyways, to keep on going, I think I will approach this differently.

I will be using a different turbo for a while. Most Likely a B16G or something. Dont know yet. What I am looking for is a good combination of turbo and engine support mods that will take me from one turbo or bottom end to the next with just some tuning rather than replacing all my supporting mods over and again.

I absolutely will have-
1.DSM Link
2.MAFT- Setup
3.3" exhaust
4.Structural reenforcement

The rest is up for grabs. Suggestions?

 

[L2RTSiAWD]

Deleted some posts.

98spyderboost-You will have to replace some of you support mods. There is going to be no way around that given the the turbo you are going to use and the one you want to replace it with.

So what can i get for the fuel and spark system that I can use with any setup from a t-25 to a HX-40? The rail? the pump? I know cams are all up to your setup.... BTW thanks
