That's not a 2.2 build though you would need a 10mm crank and to go like .060 over with a 2.0 block

You gain the displacement in the stroke. It comes out to be a 2.18L + the 0.20 overbore bumps it up dang near close. Do the math on the rod angles and you'll cream your pants.

If you're still using a stock stroke 88mm crankshaft, you're not going to be able to overbore it far enough to get a 2.2L. A dangerously oversize 88mm bore and a stock 88mm stroke gets you 2.14L. That 88mm bore is 0.060" overbore on a 2.4L block, or a 0.120" overbore on a 2.0L block. That's also as far as you can bore either block safely, you can't bore it 0.200".

The rod angles will be impressive... if you use the 88mm crank in the 2.4L block and stroker style pistons with a shorter compression height to allow 162mm rods. At that point you could have 1.84 rod ratio or slightly better.

pics would be great, i'm just not satisfied with my oil drain setup.

Click to expand...

Best I could do, Keep in mind the -10an drain flange on the turbo outlet is flat with what I assume is a hardware store 45 degree fitting screwed in. The pan -10an is flared for an fittings to screw on. Fits ok and clears the motor mount, but appears it needs a little work as it's slightly dripping some oil.

So, I have a question, did BW steal any of their ideas from Holset to build their s200, s300, s400 turbos. Because they look VERY familiar. I thought thats what a holset was at first.

James

Holset has the US patent 4930979, map width enhancement technology. The surge ports. But everyone is copying that .

The compressor blades do look similarly angled and with the same flat leading edge for the modern wheels (hx40pro, hx52 pro, and 7blade hx35)

Ok. What does the map width enhancement actually do for you? Lastly, if these turbos are slowly gaining popularity, why isnt anyone selling them in mass quantities? It seems like the best street turbo from a Holset would be a hx35/40 hybrid. We need someone to produce these for under 700 bucks!!

Thanks, I used bolt on -10an fitting's on the pan/turbo, then a 2-45 degree fittings with rubber hose clamped in between. Clearance is VERY tight around the front motor mount bracket, but I managed without any trimming. I can take pics of my drain setup if you wish, just ask.




I'm really shooting for a 10.5@135+ next spring. I managed some decent times out of the old HX-35 car with alot of stock parts/mid level performance parts. I built this new car with the intensions of dragging it quite often with an even higher then 8k redline. Only real thing I want/need from here is a SMIM and then I'll have no doubt's on hitting my goal. I may even toss a set of drag radials on it if I'm feeling really frisky, but who knows. I'll have track results and dyno number in the spring fella's

By the way, I started it up for the first time in 6 months today~!

I'm trapping 133MPH with stock intake/TB, 272 cams and a slow shifting STOCK tranny. You won't have an issue with 135+!! Then you will need a license!!

First of all the Hx35/40 does not work very well in the bolt on housings. The Hx35 turbine wheel does not flow enough for the hx40 compressor (also in this combo they only use the 58mm hx40, because aanything bigger than that and it out flows the turbine wheel even more.)

Holset turbos are not cheap to purchase brand new. The best deals are either take off turbos or companies get them from Generator companies. Either way the supply is unreliable.

Makes sense. But, i wasnt planning on a bolt on housing. I was looking for a t3 housing, maybe a divided. I read that helps take advantage of the MWE.

James

I will be a lot better off after new years as I am waiting for a deal to go threw but my goal is to be in the 9's with my hx52. I made a thread about my build in the drag section and I put up some pictures some I already posted here others I didn't. We shall see what happens because like they said it's just speculation/bench rancing at this point.

You are there Slippi.. You've got 3 of the most important components!!!
-HX 52
-JHR exhaust mani
-Jake's custom IM
-and the right standalone/AEM/

It is just matter of time.

Yeah but when your tyring to go faster than 10's there are a lot of other factors that make the difference like traction suspensions travel and what not. You don't even think about all the little stuff that adds up till you start picking it up but like you said the big things are in the mix so we'll see what happens

Were are you guys getting those ERL manifolds from? I went to their website but all they talk about is engines....They look sweet and are cheap i read. Lastly, do you guys go straight to Bullseye for the BEP housings, or through a vendor. If a vendor, which one. And how hard is the swap?

Sorry for the newb questions, just trying to learn instead of making a new thread or PMing someone. Thanks

No it's cool this is what these threads are here for. It irritates me when I see people talking about holset turbo's in new threads I"m like WHY!!! It's not liek this these threads are even hard to find. ANyway enough of my rant. If you want a BEP housing get a hold of Marty at VIP or Tim's turbos. I don't know about the ERL manifolds though I iwll let a guy with one chime in on that.

Here is one of the places, where you could get an ERL exhaust mani. I got it from there and very happy about it. These people are very nice and helpfull.

osCommerceON...

P.S. If you are getting ERL mani, you will go with T3 I guess??? It doesn't make sense to me to go with Mitsu flange, cosidering the price is the same/ for the manifolds/, and a very little difference for the T3 TURBINE HOUSING VS. BEP BOLT- on... Probably $ 50 at most, but thr T3 will make big difference in power. I would say, give Nick at Turbo trader a call at: 877-332-4705

I know, but believe me, you've got it. Forgot to mention the PTT Twin disk ...
What I noticed, it is all about the clutch. A lot of people with decent, but not crazy set-ups have ran fast times and is all due to the CLUTCH. Besides, some more seat time...

Yeah the clutch is a big part but this DS I"m gonna be picking up in this deal I keep reffering really when I get my turboner. Just a little teaser pic so people realise how bad ass this thing is here you go. 10-15lbs

^^ that DS looks like a beast compared to the stock one.

It better be for 1800 new but I mean it is CF

Plus, it is a one piece design.

With the HX-52 on board and above 6K, it will rev like a bike.

Hi guys sorry to interrupt the conversation about the ridiculously powered hx-52 but I have a question about an h1e I just bought. Here are some pics and the assembly number is 3530769 and the serial number is 063187. Is this the H1e that is comparable to the hx40? From the pics you can see it has 8 fins. Also is there a reason why the H1e's do not have that "divided compressor inducer", you know the circle within the cirlcle ( so sorry but I am an absolute newb when is comes to these holsets ) Thanks for any input.

Raymos24 -

I pulled this straight from the start of the thread.....

H1E/WH1E:

The Wh1e is like it's little brother the Wh1c. It mirrors the hx40 8blade in every way except that it has a v-band compressor cover and a 4bolt chra-turbinehousing pattern. It will consequently bolt into the hx40 bep bolton turbine housing and this is plenty of flow to max out its 60lb/min compressor.

The h1e is like it's little brother the h1c. There are different size compressors. . . BUT there are also different size turbine wheels too. Check measurements before buying this turbo if you plan on running a BEP turbine housing. There are lower flowing compressors than the 58mm 8blade that are out there. So this turbo may not flow any more than an hx35 if get the wrong one. You need at least a 58mm compressor inducer for this to be a worthwhile turbo vs the proven hx35 or 8blade hx40.





Looks as if you need to do some measuring before anything.....As for the compressor cover, I dont have an answer...

-Kevin-

Thanks for the reply. Yea I read that in the beginning of the thread also just wondering if anyone had any thoughts on it. As far as measuring goes, will I have to disassemble the turbo to measure?
