like the tittle says yunk yard turbo options for our slant six,
we know the buick grand national is a great option i just never seen one , well today at my local yunk yard i saw a 1988 760 volvo intercooler turbo,the turbo and intercooler look very nice i would like to see it pair up with my slant six,i can get this very cheep0 whats your opinion on this set up, and maybe other yunkyard turbos i want to hear your comments, thanks

A Holset turbo from a Cummins diesel powered Dodge would be a good choice for an engine with an improved head and cam. You'll need to rig up an external spring to help open the wastegate. 21 psi boost is not for beginners!

thats way too much boost for me im looking for 8-12lbs would be my goal,any comments on this volvo turbo?

What size is the Volvo's engine?

Volvo turbo will work and would be fine for a really mild build, but will run out of air flow capacity at a pretty low engine speed.

You don't have to run the Holset at the wastegate setting of 21 psi, that's just where its set for the Cummins. If you get an old one they don't even have an internal wategate. The are a T3 flange and the ones from manual trans trucks have divided tubine inlets which helps them spool up more quickly. The auto trans trucks had a smaller turbine housing which made them spool faster yet and would probably be better for a mild build. The Volvo and most all other T3 compressors just don't have enough flow capacity for a 3.7L.

the volvo engine is a 2.3 4cil pushing 182hp the turbo is made by Mitsubishi TD04H-13C i just read some guys pushing 300hp,i want to be right around 250hp,i can get very cheep ,im not saying im not interested in other options but this is very avaliable,also saw a audi turbo didnt get a good look at it hoping to go next week to the scrap yard, i would like a cummins turbo but not to easy to come by,never seen one thats for your comments

I'm using one from a '95 GM 6.5 diesel,it starts to produce boost at 2,500 RPMs on an S/6. A spring will need to be added to the wastegate to make it function properly.

V8?? We don't need no stink'n V8!!

I would try to find a stock Buick Grand National turbo from the late 80s - early 90s. Many used ones are available on turbobuick.com and similar sites. This is sized just right for a Slant.

volvo turbos are junk, the mitsu TD04 is waaaaaaay to smalll to use on a slant, it gives you no room to upgrade down the road ie turn up the boost, this turbo is done by 10 psi and een then its blowing hot air, and +1 for holset, there are other options like a manual boost controller or MBC, to keep boost in check, you could always weld the wate gate shut and or disconect the hose to the waste gate actuator and then run an external gate, genuine Holset parts are cheap, and with companies like bullseye power out there making nice upgrades for them, performance is only limited by your budget,

Are the holset Turbo chra ball bearing housing or a form of journal bearing also which model would u run hx35 or hx40 or the hy series

journal bearings on the hx and hy series, if you put the hx40 compressor wheel on the hx-35 you can flow almost 65lbs/min of air, I like the hx-35, because of the divided exhaust housing, and it should reach full boost by 3,800-4,000 rpms, cold diesel exhaust can't flow like hot gasoline exhaust , not only that but i got a take off at 56k holset hx-35w with zero shaft play for $225 shipped, but the great thing about holset is parts are interchangable found over at http://www.turbododge.com/forums/f10/f7 ... olset.html

HX35:

The 8blade hx35 has a 56mm compressor inducer. This is found on 1995-1998 cummins manual pickups. The compressor flows 52 lb/min according to the compressor map. The bolton BEP housing (0.55 a/r) is enough to push the limit of the compressor. There's several 500whp 8blade hx35 cars out there with the bolt on housing. It reaches 20+psi by 3500rpms in 3rd with 272 cams. Smaller cams would equal a faster spool speed in most cases.

The 7blade hx35 has a 56mm compressor inducer. This is found on the 1999-2002 cummins manual pickups. The compressor flows 60lb/min according to the compressor map and logged results from a member here. The bolton BEP housing with the hx35 turbine wheel do not SEAM to have enough flow to really reach the potential of 60lb/min. But many have logged over 50lb/min so far and seen 500whp. The stock hx35 12cm^2 twinscroll turbine housing is a t3 flange housing. This mated to a NON-divided runner manifold has produced a 132mph trap speed with a full weight 1g AWD. This is about 600whp. So the flow is there with the stock housing if you use a non-divided manifold. The spool speed of the 7blade hx35 is similar to the 8blade hx35 with 20+ psi by 3500rpms in the bolton housing and by 4000rpms with the stock housing with a non-divided manifold.

HY35:

The hy35 has a smaller turbine wheel than the hx35. And, it has a turbine housing connection that does not allow for a bolton housing to be used. It does not have a divided housing so any t3 manifold can be used effectively with this turbo. It has the same compressor as the 7blade hx35. We don't know if te hy35 turbine wheel and housing is enough to reache the 60lb/min potential of the 56mm 7blade compressor. Some one try it out already!!! It should at least be a faster spooling viable option to the full t3/t4 50-trim.

H1C/WH1C:

In 1994, there was the Wh1c which has pretty much the identical compressor as the hx35 but with a Vband compressor cover. The turbine wheel is the same. It will bolt into the BEP bolton hx35 turbine housing. It has 4 bolts at the housing instead of 6. So you will need to buy 2 more bolts and use 6 washers cut to make a flat side. Honestly, I just used bolts that were cut a little short and the bolt head was wide enough to pull the chra to the turbine housing. No sealing issues. Since the Wh1c is for all practical purposes an 8blade hx35 the spool and flow is the same too.

It comes on the INTERCOOLED 1991-1993 cummins pickups. It has the webbing for MWE but no groove cut like the hx35/wh1c has. This turbo I term the big h1c because it has a 54mm compressor inducer and same exducer than the 8blade hx35/Wh1c. The other h1c is the small h1c found on the NON-intercooled cummins pickups. This has a 50mm inducer but only 7blades and has no webbing for MWE. Less blades helps flow, but so does a larger inducer diameter. The most whp ever recorded on a gas 4cylinder with the small h1c was done on a KA24 nissan: 411whp. Since the big h1c has a 4mm larger inducer and the same turbine wheel as the hx35, it is safe to say that it flows enough for between 411whp and 500whp. The diesel sources state that it flows SLIGHTLY less than the early hx35. So 4lb/min less than the 8blade hx35 puts the flow of the big h1c at 48-49lb/min right where a 50-trim or 20g is. The small bep housing is all that's needed to get the most from the compressor and the spool speed is 20+psi by 3500rpms.

HX35-40 hybrid:

Keeping the long tradition of the marriage of sportcompact and hybrid turbos, there is the hx35 turbine and the hx40 compressor. It is strongly recommended to use the large bep turbine housing or the stock hx35 turbine housing with an non-divided t3 manifold for this turbo. The small bep housing around a t31 size hx35 turbine wheel is probably not enough to merit any of the hx40 compressor wheel upgrades. 20+ psi by 4000rpms can be seen in the hx35/40 with the hx35 12cm^2 turbine housing with a non-divided t3 manifold. With the large bep housing, spool times are to be determined. But likely similar.

HX40:

The 8blade hx40 has a 58mm inducer and flows about the same as a 60-1 (around 60lb/min) with ALOT better high boost efficiency and spool speed. It is the most common hx40 out there. The small bep housing with the hx40 turbine wheel is plenty to reach the full potential of the 60lb/min 8blade hx40 compressor. 20+ psi by 4100rpms with 272s.

The 7 and 6 blade hx40 is called the super40 and has the 60mm compressor inducer. This compressor flows around 69lb/min. You can get this wheel in billet style (think HTA). The non-billet wheel spools as fast as the 8blade hx40 in the bolton bep housing and has done 653whp at 40psi per the holset results only thread. Billet should spool even faster. The t3 .70 a/r BEP housing slows spool about 400rpms. But reports show a significant gain in flow per psi. So expect more power at lower boost with that turbine housing.

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.

HX52:

This is a big sucker. It is commonly found on the Volvo Semis and usually has a billet compressor wheel. It flows 88lb/min. There is no bolt on housing for it. If you want a bolton housing for this turbo, then you don't want this turbo. In fact if you want a t3 flange turbine housing for this turbo, then you don't want this turbo. You DO want this turbo if you're looking at a gt4294r or gt4202r. The turbine inlet is slightly different than a t4 bolt pattern. You can still get the t4 manifold to work just fine by enlarging the bolt holes.
