Why is my name brought up again? Kevin ride in my car and tell me if you like the BB scm6152, you will!

900-1000 for a turbo isn't too bad of a price, but isn't really all that "low budget" of a setup that everyone rants and raves about. I paid that much for my BW with a T3 housing.

[wheelhop]

To he!! with BW. Bullseye sells those turbos!

Back to your comment. It makes sense. But think about it. T3 housing (stock housing) turbos are always cheaper. Take a look at how much a holset with a stock turbine housing will cost. How much does a bolton BW cost? The bolton s256 costs $300 more.

The budget minded builder can't get other brands used a dime a dozen. And if you have the opportunity, you have should weigh reliability, spool speed, compressor efficiency, rebuildability, etc.

Same hx40 car launching. No studder or antilag in 1st.

I paid $400 got my HX35 in a bolton and I can/could get a HX40 the same way for about the same price.
oh yeah came with oil feed and return lines and OP fitting for return line.

[wheelhop]

If you look around the diesel forum classifieds and know what you want: what I paid.

I could have bought a TiAL external and still been under $500 total.

[sleepydsm]

theturbotrader has HX35 with bolt on NEW for $875.

Used Hx35 goes for 300-400 for a nice one, new housing is $380, and then add shipping. I might as well buy that new one for a bit more...

But I secretly kinda want a FP3065...

[wheelhop]

No $280 maybe, not $380. . . See here. $630 ($350 hx35 + $280 bep housing w/internal gate) is $250 less. You can get an external gate o2 housing and TiAL external gate save $50 from not using an internal gated BEP housing and pay $1030 total! External setup that bolts on like an internally gated 20g turbo to your current exhaust system. . .

Why are you looking at the bolton hx35 when you're also looking at the fp3065 ? They are different frame sizes. The hx40 can be had in bolton form; and in that form is proven to flow as much or more and proven to spool faster. Save the $500 for a SMIM.

. . . Oh wait, you need the vband o2 housing or exhaust hookup for the FP turbo too. . . A portmatched evo3 o2 housing is fine for a bolton hx40. OR you can buy a tubular 3" with an mhi flange for far less.

Jesus wheelhop, you sound like me campaigning for Megasquirt...

I might have to try a hx40 on my suicide 2.4 buildup this spring, if nothing else for another data-point for us local MN guys.

Just out of curiosity, is BEP the only shop using mating mitsu housings to the Holsets? Are they any dyno graphs showing the difference between the T3 and mitsu housing?

[wheelhop]

The only shop that I know with a readily available housign. There are dozens of guys with other platforms that have had various garrett housings cut for the hx40 and hx35 turbine wheels. There's even a DSMer that has cut a used FP30 turbine housing and fit an hx40 onto it .

There's is no mph or dyno side byside comparison. The larger .70 a/r housign does spool about 400rpms later.

Hey Wheelhop, do you work for Bullseye?

[wheelhop]

You're better at tetris . But at least a good job keeping this thread on top.

Here's the pic I was looking for. FP housing on a wh1e (hx40). You can see an adapter ring had to be used. That fp housing was bought used. If you buy new, buy the non-GTbb FP30 turbine housing since it has a deeper mounting area. . .
