If cost was not the deciding factor which is a better drag racing/street driving setup? I can get a deal on a 35r for not much more then it would cost me to do a holset setup. Let me hear your opinion.

It depends if you want to go with a Garrett T3 manifold and fab up an o2 housing or not.

If you want to stick with a Mitsu housing, then the HX35 / HX40 would be the way to go. Actually, I'd prefer the Holsets over a ball-bearing GT any day, but it's hard to pass up a good deal. The HX35 is comparable to a 50-trim Garrett on steroids- the HX40 is more versatile in overall performance than the GT35R.

Is the GT35R new?

Go GT35R ...

Borg S362

Holset simply because they can be rebuilt and spool a bit faster (depending on which you get)

iF your gunna get a 35r why not make it interesting and get the new FP HTA3586

which i believe is the same as the Bushcur FS635 that he ran 9s on pump with

But cost is a factor which is why I say hx40 with t3 .70ar all the way

^^^ I would have to agree with slippi.

I would also say straight HX40. I would stay away from the hybrid hx35/40. The Hx35 turbine wheel is too small for the flow capabilities of the hx40pro wheel. (which is the one to get)

As far as for street, the HX40 definitely spools the GT35R by a lot and doesn't sacrifice any power as the rate is 68 lb/min high power/torque for drag purposes.


Without a doubt the HX40 is worth the money in the reliable factor and power as badman21 has put down 653hp.

I dont find the holset HX 40s as easy to find as everyone says they are. I also never see anyone post which one it is (how many blades...etc) Ive been looking for them and I find them on Ebay everyone in a while but I dont now how to tell them apart and most of the sellers dont know crap about the turbo's.

With that being said I would go with the turbo that spools the fastest which would be the holset no mater which one you choose (the HTA Gt35 will probably spool close to the hx 40 though)

I would aslo say holset just because they are built to last, and hx 40 pro is a beast. Which is the one I currently have on my car now

The HTA spool time is pretty much equal to the HX40, but it's $800 more than the BEP HX40 which is a pro 7-blade. As for buying a cheap one in the $400 price range off of eBay just go by the pictures and look for the 7-blade ones. Either way Holset is better and can take a hell of a lot more beatings after all they are made for turbo diesel trucks.

Spool up and cost were the determining factors why I went HX40pro. I picked up a new 7-blade (69 lbs/min capable) for $515 after shipping from ebay. You really just have to check there every couple of days and you will deffinatly find one sooner or later.

My original plan was for a FP3582HTA. Although Im nowhere close to getting the new setup running, I don't think Im going to regret the choice.

GT35R. I see you have an hx35 in your profile as soon to be installed. For the most part, you can't swap on a compressor wheel to your turbo and expect it to be capable of making the power the bigger wheel can support. You could go with the stock hx35 turbine housing and a non-divided tubular manifold and then it would be worth it. But even a later hx35 has a 60lb/min compressor that will probably be all you could get out of a stock hx35 hotside. Anything is possible. Wheel matching is not cut and dry. But we really need your goals.

Unless you'll look at the hx40. The hx40 with the bep housing can be bought new for less than the 35/40 hybrid, from what I see. So what are your goals? Are you going to do a t3 setup? you're talking about a gt35r: will this be a bolton? You may just need an hx35. Or an 60lb/min standard hx40. You need SO much more to make either the hx40 or the gt35r worth the install.

HX40 Pro (my 2 cents)

ok guys let me clear this up. I have access to either a new 35r or a holset 35 or 40. The 35r will be a full t3 setup. I'm looking to run mid to low 11's in a full weight tsi awd. 272/272 combo smim and supporting fuel system and either dsmlink or a chip from jeff @ dsmchips and an safc for minor adjustments.

The HX40 could put you in low 11's using a Bulleye bolt-on turbine housing and the ported 2G or Evo III exhaust manifold you already have, so you'd save the cost of the T3 manifold. Just go with an external gate off the o2 housing and you'll be in good shape.

Eventually you may want to go full T3 if you're planning on making big power, but for now the HX40 / Mitsu housing combo would be a more economical choice. It's just a decision of how much you want to spend / invest at this current time.

He!! even an bolton hx35 with stock manifolds can get you into mid 11s. Mike did 11.2@126mph.

Only 1 hx40 user we know of has even pushed the turbo. They are proven 600+whp turbos. And 600+whp does alot better than that at the track. So I agree with Justin, your goal is very conservative for a bolton hx40, and of course the gt35r. I would use the straight hx40pro with the bolton housing. Then later upgrade to a t3 .70 a/r turbine housing and better o2 housing/exhaust manifold. Even the 8blade standard high flow hx40 (58mm inducer) can easily do this. . .

Here you go:

The Turbo Trader

They usually don't have them instock, but they can get them in a day or two. There are cheaper ways to get an hx40, but this way you know what you are getting and it is still cheaper than buying a new GT35R.

Thanks for the link but ive got plenty of time to look for an hx40 on ebay before my current turbo craps out on me. Ill just keep counting the blades until I see a 7 blade on there or craigslist.

6-blade or 7-blade, either will do 70lb/min (60mm inducer). The 8blade is a 60lb/min compressor (58mm inducer).

There is one guy running a 60mm 8blade h1e. That's an oddball we havn't seen anywhere else. No one has a compressor map of that around here. But it has to fow between 60lb/min and 70lb/min .

The good thing about buying new is you're sure. I like hunting around for deals. But many won't put a used turbo on their car, and for good reason. At least the price of a new holset is around the same as the ol' garrett t3/t4 prices. Which is VERY affordable for the results. I've had very good dealings with theturbotrader.

I keep waiting for someone to do something interesting with a holset. Supposedly they are less laggy and make as much or more power, but they're consistently way down the list at DSMtimes. Is it just because it's a cheap buy in to a large turbo, but the rest of the car isn't ready yet?

With the numbers from an HX-40 I would expect to see a lot more low, low ten second cars running them.

That's nothing against the holset, since they appear to have good maps and make the power (in the T3 & T4 hotsides) I just haven't seen anyone really push it the way maybe it could be?

It's part of why for proven go fast badness I'd lean towards garrett- simply because the limits are pretty well defined. Less exciting, but r&d on an unproven setup while rewarding, can be costly.

super SUPER true. Its not even that it wont make the power, the turbo just wont last. I was askin people (bc i owned/ own a business) about slappin a 42r comp wheel on a precision t3 or even mitsu w/ stage 5 turbine wheel housing and i only ran across 1 company that even tried it and although it made BIG horsepower with minimal spool, the thing apparently lasted 2 dyno pulls haha.

Holset hx 40, or bw s362

Seems like within the past yr or two,they(holset) seem to be slowly but surely becoming popular with us DSM guys. But that's a good question you post there concerning times and popularity.

Alot of the EVO guys use Garretts I think mainly because this is all most of vendors will sell due to popularity based on what Mitsu guys like.

Other than Hondaguys seems like there are alot of Euro car guys and even Ford car guys that use Holsets.

But yes I'd finally like to see some low DSM times posted using these wonderful turbos.
