Holset HX35...

[tsiconquest88]

Is this turbo setup the same as the hy35? output are different but mechanically i was wondering if its going to be the same modifications as the hy, i have been seeing hx's cheaper than the hy's time to time, and figured maybe i will just go for an hx in that case if no serious changes are needed that would end up costing more than the mods needed for an hy35.

[t3rse]

Your question doesn't make any sense to me.

Hx35 has a much larger hot side and will take longer to spool. The turbine housing flange is the same bolt pattern. The exhaust is different between the two in that they use different size v band clamps. This information is all over the place...

[tsiconquest88]

um seemed just fine to me. you pretty much answered my question minus the sarcasm. All i was saying is are they made the same physically meaning the same mods you have to do for an hy will be the same mods to do for the hx. The hot side is bigger yes but physically thats not causing me a differenence on bolting it up. However how much slower of a spoolup would i get from the hx over the hy with that bigger hot side?

The HY bolt on housing outlet is the same as the HX (pictures in the Holset KC article). Like you said the HX has a bigger 12cm hot side so it might push the connection just slightly to the passenger side but the flange its self is the same and the compressor wheel/housing is also virtually the same on the '99+ HX and the '01-'01 HY.

While some people have called the '03-'06 turbos HYs the generally accepted naming is that only '01-'02 9cm housing turbos are actually HYs and the newer models are HE341 and HE351.

[tsiconquest88]

yea i basically wanted to just know if it would be worth doing the hx over the hy if i got a deal. Or should i not even bother.

[t3rse]

Valid point. The He341 has the 90* compressor outlet and Hy35 has the straight compressor outlet.

conquest: Look at the KC article. I couldn't tell by your wording if you meant that the turbos would be physically interchangeable or if you expected similar performance.

[tsiconquest88]

yea i read that before i posted but it dont tell as far as the physical attributes if i need to do more to make it compatible for a tiii than the hy35 and such inf as that. I didnt want to get this hx if i was going to be looking at a whole different swapping aspect over the hy. I had found an hx for 100 bucks. some shaft play but rebuild kits are only 45-60 bucks. here is a pic of it http://i36.photobucket.com/albums/e45/tsiconquest88/3nc3p03oc5Oa5T15P3a1jb88bd4508c861e.jpg

HX35 will be too laggy on an 8 valve unless some serious porting and manifolds.

[tsiconquest88]

not 8v simon, for a tiii. ye or ne? lol

[t3rse]

For that price go for it. It will be close enough that you won't have problems switching over, and the HX will still be a little laggy on the 16v but you'll be able turn it.

[tsiconquest88]

hrm, wont be as laggy as stock would it lol? Not looking for high boost on it either, just something to grab some better spoolup and power increase.

[t3rse]

The holsets don't really wake up until 20+. It will make solid power at 15# though....at least from my experience.

[tsiconquest88]

wow i found a link on google for a direct comparison for hy35 and hx35 and the hx is QUITE a bit larger, more so than i even would have guessed. i think im going to pass!!! see for yourself lol...

There are differences between the '95-99 HX and the 99+ HX that should also be considered. The compressor wheels are different, etc.

I see the same specs on the late HX and HY compressor wheels most of the time but I haven't tried to interchange the compressor housings or anything.

I have seen the specs on the compressor inducers as both 56mm and 55mm. They are actually hard to measure with a caliper.

I should probably buy one like the broken one you mention so I can measure it and add it to the KC. I can always have it rebuilt and then resell it so I won't lose any money on it.

Your not going to beat the stock turbo for spool up, you have to make trade off's.

As said, the Holsets are more of a higher boost turbo, most aftermarkets are. If your looking for an upgrade, and good spool, you should run an S60 type turbo with a .63 turbine housing.

[tsiconquest88]

good to know, thanks simon, these are all thing im looking for for info. I was told and seen go with holsets and such but really i just want some more power with a faster spoolup. how about the clipped/fast spool option for the stock rt turbo that the vendors offer?

[tsiconquest88]

rbryant i know one of the main differences between the 2 different hx35's is earlier had 8 blades and later has 7 in the compressor side.

A stock TIII spools like a mofo, not sure how much more you want, :confused:

If you want more power and the same kinda spool, go with the S60 I mentioned earlier, :thumb:

[tsiconquest88]

no simon, something that spools up fast at a lower rpm, like how fast the little mitsu spools the 2.5 off the line lol. i know the 2.5 is more of a bottom end torque monster over the 2.2 but i figured you could alter a lower rpm spoolup on the tiii as spoolup dont hit right away.

[bakes]

I think one thing everyone is over looking is if your a stick or auto that a larger turbo is being put on to .

I am guessing he has a 5 speed, it's a TIII. :thumb:

[tsiconquest88]

lol, yea but im kind of off on some of this i think. I just want a turbo that will let it take off like the mitsu does for the 2.5. not as much lag ya know.

[bakes]

Give Simon a pm on the Vnt setup he's workingon if you want quick spool

[rbryant]

rbryant i know one of the main differences between the 2 different hx35's is earlier had 8 blades and later has 7 in the compressor side.

Yep that was one of the differences. The earlier ones were also bigger.

The question is whether the late 7 blade is exactly the same compressor wheel as the HY or not. I am lead to believe that it is but I haven't verified it yet.

-Rich

[tsiconquest88]

ohhh i didnt realize thats what you meant, yea idk on that, and though they LOOK like it in the comparison link i posted above, thats impossible to say for sure without a caliper measurment. Well if u want it i can give you the contact. Im not bothering with it. I was thinking of buying it anyway to rebuilt and sell (i have a rebuild kit for the hy/hx35). He said there is some shaft play. However its probably nothing as straight oil turbos usually are a little looser when no oil is present in the oiling area. I had a brand new master power t-70 have shaft play when it was new and once i put it on and eventually ran the engine it ended up tight after that inital run. I think tolerances are tighter on coolant cooled turbos. Thats what i have seen on every oil cooled turbo i have had in my possesion wether mine or not. and though i havent had one of these turbos in my hand, mitsu water cooled were always tighter.

I think you are missing an obvious point: a larger turbo is never going to spool quicker without VNT. You want quicker spool, get a smaller turbine. I can't see how you think the stocker spools slow. Are you sure you don't have a massive manifold leak?

[tsiconquest88]

as i said im not saying tiii spools slow per say, but i would like to get the off the line power the 2.5 has lol and the high rpm the 2.2 has lol. Obviously the tiii dont spool as fast as the mitsu and smaller garrets and smaller turbos in general, but they dont make the fast spool option for the tiii for nuthing lol. I just was wondering if there was a turbo that offers fast spool and more power on the tiii 2.2 engine over the stock turbo. To put it simple. I will just send mine in for the fast spool option and such from FWD.

[Ondonti]

there is no such thing as a fast spool option that actually works. Be prepared to want to sell your turbo after you reinstall it.

The only way to get what you want is to use a smaller turbo and make less hp or figure out a variable geometery etc turbine setup.

I know some people have managed to put some sort of super 60 wheel onto the tiny Garret VNT turbo. Problem is that your bolt pattern is all wrong on the TIII. Don't know anything about other available VNT's

[Millerman340]

You can get a Holset to spool almost as fast as the stock TIII turbo & heres how.

[Millerman340]

It might choke it some on the top end but I honestly can't tell the difference in spool up other than the getting rear-ended by a semi feeling...Starts spooling about 2500 & is full on 20 lbs by 3 grand.

[tsiconquest88]

idk what route im going to go. i mean yea the t3 kicks u in the --- but it takes a couple secs for the power to do so. thats the lag in speaking of over the 2.5 which is instantly with the mitsu and almost instantly with the garret 2.5's but slowest is the t3 lol. which takes a few to kick ya. i was trying to hunt around for a faster spooling, but in the long run its probably better off for traction. if i had as fast of spool as my vans little mitsu in the power of the t3 it would sit there and spin. least i get some movement before the tires light up lol.

[Millerman340]

What is this lag you speek of?:eyebrows:

Lag in a stock TIII? are you kidding? There is no lag, the turbo comes on NOW, :o

You can't have your cake and eat it too unless you go VGt/VNT.

There is no lag on a stock turbo TIII, what are you seriously talking about? :confused:

[tsiconquest88]

um no, 2.5 mitsu is instant. My t3 is much laggier. it is NOT instant. your just being fasicious. BTW Simon you have a t3 head on a 2.5 bottom end of COURSE yours is not laggy. the 2.2 bottom end is known to be laggier than the 2.5 from what i gather people saying about the difference of the 2.2 and 2.5. I did rev it out good too, got it to 6500-7k 2nd and 3rd. Not the day the shft went out though luckily lol. i was just driving on the highway a couple days later when it happened. Going to the docs, where i missed my apointment to boot.

[rx2mazda]

I have to agree with Simon on this one. TIII lag is non-existent. What are flooring it at 1K rpms in 5th gear? lol. I think the difference you are felling between the two has little to do with turbos and more to do with engines. The 2.5 is a stroked 2.2 so it's a low rpm torque motor, that's why it feels great on roll in. If you drove both cars, without turbos, the same characteristics would be there. I think your barking up the wrong tree here.

[turbovanman²]

I am not talking about my van, its laggy and that's ok. I just drove a 92 IROC R/T I did the engine in, stock turbo, stock head, stock cams, XS power FMIC, 3 inch turbo back exhaust, degree'd cams, 3 bar map, FWD cal and there IS no lag, boost comes on instantly and first gear is useless from a standing start. On the freeway, again, no lag, in 5th gear at 2800 rpm, 70 mph, floor it, boost comes on instantly and your gone.

Drove a bone stock 91 Spirit before, with only a cat back and again, no lag. :amen:

[tsiconquest88]

i got lag. so yea. now the mitsu in my van- THATS what NO lag really is lol. But really im not going to bother with this thread any longer. its useless and personally i think its stupid to even make argument over. i simply said i would like to get it to come on quicker and its been a losing battle ever since. and wHY? theres no way it had NO lag, the little mitsu is NO lag. Beside that, rx2 of course im feeling what you mentioned but i doubt its just that. But whatever, the 2 seconds wasted for boost to come in in every gear when i floor the car at rpm's above 3k is much different than i feel with my van's mitsu turbo.

[turbovanman²]

Sounds like there is something wrong with your car, if the boost came on any faster with a stock turbo TIII, you'd be just sitting there spinning, :banghead:

Forget, 2nd gear is pretty much useless too, :nod:

[tsiconquest88]

well you got to look at it this way, yea 2nd is useless with stock rims/tires but with these pumpers and the straight street perf tires it has its much grippier than what otherwise stock tire size would get smoked up. 225 50 16's and these tires it has are quite NICE!!!! i can take advantage of 2nd pretty nicely. So yea i could get boost quicker and be OK. but as i said i too said above the little lag over what my van has is a good thing. afterall a 6500 redline over a 4500 redline is going to alter things a bit too.

[Millerman340]

Yea I agree on the mitsu being on, hell it's boosting at idle. But for real Once I launch the engine hardly ever sees below 2500 ,so it's always in boost& it's alot larger than the stock Snail to boot! Sure if you lug the engine down waiting for the boost to come than it will be laggy. Except for the mitsu ! By all means put a mitsu on there if it's what you need or swap it for a Spirit ES turbo for that 1000 rpm grunt.:)

[tsiconquest88]

yea, and i dont launch so i see the lag lol. i mean im not saying the lag is anything substantial, and i think these guys are getting a little carried away over what amount of lag im speaking about. i just was seeing if anyone knew of a way to get the t3 to spool like the mitsu setup does on the t1's and such. However if i pump the boost up to 15 or more once i get my cal from rob. That will increase response time too. In fact my boost is only at 8 psi or so right now anyway lol. manual controller.
