HX35 powered DSM's

[Xavier]

I've been able to wittle my wish list of turbos for my Talon down to three. Right now the Holset HX35 is lowest on my list so i'll give it a fighting chance by asking anybody local if they had good or bad experiences with it, and whether or not the capability and durability is compromised by putting what was designed to be forced induction on a diesel, onto a gas engine. Looking for opinions on the HX35 only, and local first hand impressions are much better than some guy who slapped one on his GST all the way across the country.

Thanks beforehand.

How do the housings hold up if you increase the BOOOOOOOOST?

I swear I have heard they like to crack. Just looking out.

[northendtrooper]

^^^ Wrong. To bolt up to a dsm, you have to get BP housing, which to my knowledge doesn't crack.
I only know of one and he's in Eastern Idaho so being local your outta luck. I have been talking to a few people about it and they said they love it for the price. From what we've talked about for a baseline, one had DSMlink and fuel mods of 780cc's, pump, fpr, and put down 350whp on 18psi with stock cams, and HG. Pretty sure with your Cams and getting more mods down the road to support 25psi you can get over 420whp.
The HX40 pro is going to be my choice of weapon for I'm seeing close to 600whp on 30psi.

[CHRIFFIN]

ahhh thanks for clearing that up austin!

Yeah i would have to buy the BEP housing to make it bolt up. but i was just wanting to make sure i could push north of 400 WHP with the HX35 (i don't see needing anything bigger than that unless/until i go built motor) With the example you just gave me it may have jumped a place on my list. But it's still the factor of it being a turbo that was designed for a diesel being but on a relatively high revving motor (compared to a diesel) that scares me.

How much research have you done on it?
There is 6 threads of continuous info on Holset Turbos alone in DSMtuners. If you have big enough cams the HX35/40 spools just as fast as a 20g, roughly full spool by 4k. Also the 35x is capable of 52lb/min and the 40hx is I think about 61lb/min. With the supporting mods (Cams, HG, ARP head Studs, Fuel, Clutch,) you can trap 120's all day.

I've done alot of reading and checking out flow charts and shit, but it's still alien to me. The whole diesel turbo on a gas motor thing. I wanted to see what had been done locally with them, but now the Hx35 is definitely on my second spot on my list.

EDIT: Can't sign up on Tuners, i don't have an e-mail account that i pay for. It's lame.

[northendtrooper]

Don't need to last time I checked. They fixed that I believe.
Turbo is a turbo, it is spooled by exhaust gas and builds boost from compressor housing, it uses the same oil, etc. The only thing different is the Exhaust housing. Remember though, these are stock turbos built for high boost applications so they're good to go and cheap to rebuild.

[carfreak]

Its going to blow up...

Anyways just get a 42r and call it a day....

[Xavier]

Its going to blow up...

So be it if it does. All the more reason to go built.

I don't make that much money. And i can't save up for long enough.

Now that i signed up on Tuners and read the tech thread for the 35 i'm feeling surer by the minute i'll be getting that turbo.

[zex_cool]

holset he351cw, get on it!

[goblin]

People really seem to like those turbo's. Just make sure you have the fuel and tuning software to be able to use the thing.

Kevin

[northendtrooper]

Well considering the fact that you can snag a decent condition Diesel Turbo for under $400 with BEP housing and they're lasting some time, wouldn't you consider one? I was about to get a damn HX40pro but my "ken block" incident kinda fucked me over.

[goblin]

You got out of that driftcapade pretty cheap. I all but gave you the knuckle.

Kevin

[northendtrooper]

And I am forever grateful.

[Xavier]

ROFL at Ken Block reference.

ECMLink is on the list for parts to buy. And i have Travis old 750's

[northendtrooper]

Go bigger on the Injectors you'll hate having 750cc with that. Try to get over 1000cc at least. Also you're getting the V3Link? Tell me how it is.

[goblin]

Are you goin gto run pump or E85?

Kevin

[randomtuner]

If youre going with any kind of Link... V2 or V3, you might as well get 1000cc+ injectors. They all idle the same with Link and you know youll be using them.

When my wallet allows i will get it, hopefully within the next couple of months

If i could get e85 on a regular basis out here in BFE i would be all over that, but alas, the best we got out here is 93 at Stinker or shell.

I've been pondering if my 750s we're going to be big enough. Damnit maybe i'm gonna have to rethink the fuel plans.

[northendtrooper]

You will. Travis had his 750's at 110% IDC with his 125mph traps. You'll need at least 1000cc to get safely in the mid 120's

[Xavier]

Alls i wants is one 120.000001 MPH Trap, you don't think my 750's will get me there?

[northendtrooper]

Barely. I would say you're pushing it. I think the IDC will be in the 90s which is not good for injectors especially those that have been over 100% before.

[Xavier]

Why you always gots to be bringin me down Austin?

Grab a used V2 and pay for the upgrade. It might be cheaper.


If you can get 1000cc+ injectors for the same price as 750ccs and theyll both idle the same with Link, why not? Better to have the chip burned once then to have to send it back to do it again for bigger injectors.

[goblin]

You can change injector all day long with link and all you have to do is change the globals. There is know need to have the chipped burned again. ALso V3 has flash memory so even if the battery goes dead the last tune saved will still be there.

On race fuel your 750 maybe big enough. I'd run them, watch your IDc and see where you are.

Sure getting bigger injectors would have been smart but you already have the 750's so see where you are before tossing more money in the fire.

Kevin

[Xavier]

I want to order V3 brand new, just so that i know everything is there and that nothing has been cut that might be necessary for my setup, just to make it easier. I thought about buying V2 and updating but i figured WhyTH not just by V3?

Yeah i was thinking of just running those until i got bigger injectors later on down the road, but i wasn't sure on whether it was necessary to ''burn the chip'' again for bigger injectors. Hadn't read that much into it. Thanks for clearing that up.

[d_moss]

You can hit 120s with 750s. I like the drivability of the 750s over my 1150s. The 1150s miss and run crappy for the first 10 seconds of start up. Also I lost the remote start feature on cold days because of this. You have to be in the car to give it gas for a second. It also doesnt cruise super smooth. at a certain load there is a miss every once in a while. Maybe v3 can tune this out. But I have not got them to run like stock yet.

Practice makes perfect. Bigger is not always better. If your a manual think you have to respool that thing between gears. I gained 5 mph and .7 sec by driving and shifting different. 120-125mph.

[northendtrooper]

What were you tuning with? Sounds like your globals on the Injectors were way off.

That's what i like to hear. I'll do what i can with the 750's and if it isn't enough fuel for me then so be it.

As I've said before plot your data points (initial boost rpm and pressure, full boost rpm and pressure and max rpm and boost) on the compressor map and see where you match up. I considered this turbo for the VH45DE going in my Z and I'm just on the verge of the highest efficiency island. See where your points are at, I can help if you'd like. You have to keep in mind that the turbo was designed for applications around 20 lbs and around 2300 rpm on a 5.9... so if you do the math a 2.0 liter, running 20 lbs gives you roughly 6450 rpm... should be pretty spot on depending on what boost levels you're looking for.

All that being said, they're terrific turbo's, damn near indestructible, incredible spool characteristics for a non bb turbo. Plus you can get a turbo and rebuild kit off ebay for under $200 on a good day; and the components are big enough you can easily rebuild them yourself. Pretty damn hard to beat. Lastly, they're incredibly well engineered, big fat efficiency islands due to both wheel and housing design which means a highly efficient setup under a pretty generous range of conditions.

[Xavier]

Yes, that's exactly what i wanted, thanks for the info. After comparing and whatnot i'm pretty sure i'm getting the hx35.
