Now I have Evo III turbo from Mitsu, do you know if there are housings that have the same flange so I could bolt it to my manifold?

Also where should I look for some HX35(if it will do 550hp)?

Funny you mention the DSM bolt on housing, but I'm a little confused which flange is where. You need the ex housing to bolt up to a mitsu flange on the ex manifold? If so, they do indeed make a very popular housing that comes in .55 a/r and .70 a/r for the holset that bolts up to a stock mitsu manifold. You'd still need a custom downpipe made though.

Here is my turbo, MHI Evo3 16G

No problem to make a downpipe at all... Just takes time

I was surprised too, and decided if others can do it, I can aim for 500hp at least Here's his thread, take a look. I like such builds when bags of money are not dumped into the engine but it performs - 577whp@2.35bar http://sxoc.co.uk/vbb/showthread.php?t=375692 Hmm, 134mph was achieved with GT30R by this same guy... You say DSMers get only 132 from HX35... Not very impressive then?

If he trapps 134 with a GT30r, he must weigh less than 2500lb's! The DSM guys that ran 132 were at full weight (3100). They run slower times with GT30r's. Also keep in mind, an HX35 will probably outspool a GT30r, but the main thing that I'm saying here is that they are the best performing turbo out there--it's just that they are so damn cheap AND they are awesom performers.

Cj, its nice to hear you're so confident in the holset turbo's performance, as I have one in the mail currently. I also have an rb20 and somewhat high power goals in mind. High power and quick spool are never easily accomplished on the Rb20.

......You've never heard of my s13? Its the 240 that made the Kessel run in less than 12 parsec's...

I'm looking for a modest 350 whp on my first tune. I think thats quite a bit for the rb20, and for an s13. However, I'd be shooting for more if I had larger injectors. I have 440cc injectors currently, and I think the highest safe hp level will be around 350. I'd imagine I'll need to run around 15 psi to achieve this, but I'm really not sure.

How much boost are you going to run, Matt?

I'm trying to get all the parts I need to finish my setup, but I am still waiting on my turbo to get here. Trying to get my car back on the road asap.

Thanks

Here's a couple of vid of my old HX35/40 hybrid if anybody cares to see.

This swedish guy's had a lot of high Hp CA vids on youtube for a while now, but just recently achieved his 577rwhp tune. I found the video to be pretty much awesome...

I believe its norris designs who has the 650ish hp CA18 in europe. They achieved somewhere around 187 mph with a few issues a while back, wish I could find the damn video

Big props to the little CA

Also does anybody have any pictures of the Bullseye performance housing and how big is the vband on it if i get it non wastegated. And i have the 8 blade hx35. Still good for 400whp????

Those vids are damn impressive. Did you see how bad that thing was compressor surging BTW? That is compressor surge, not that noise people whine about when they let off the gas from boost.

I'm confused Cj, after reading this....

"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."

What makes the rb20 not capable of achieving the same power levels? Are you saying that it wont make this power without running obscene amounts of boost, or are you saying the head is that much more restrictive than a 4g63 head? Keep in mind we are running the stock divided 12cm2 housing instead of the smaller BEP bolt on housing, this should give us a power advantage at the cost of a few hundred rpm of spool.

There's a couple of 500 whp RB20's in the SAU dyno thread that have stock heads, cams, and bottom end parts. Granted, this is at 23-27 psi boost. If you'd like me to link you I will. I'm not dissagreeing, I just want to know what you know lol.

Thanks

Matt- 52lb/min would be AROUND 520hp at the motor max, but at who know's what boost. 12% drivetrain loss would around 60hp, so call it high-mid 400's? Than knock 20-30 off for not running 2.2 bar and I'd guess low-mid 400's at the wheels on the 8 blade. That's a whole lot of bench racing though. I have a HX35 compressor housing and wheel sitting around somewhere. For sure 400rwhp though. Let me count the blades on it and I'll get back to you to see if you'd want it.

3rd gear - .5 bar by 3.5k rpm
- 1.0 bar by 4.2k rpm

4th gear - .5 bar by 3.2k rpm
- 1.0 bar by 3.9 rpm

That's with the 19cm housing, RB26 ITB's and surge tank (short runners), 1.2mm headgasket (lowers the CR a bit), HKS 264 cams, and no VCT.

What all would i need to make this work on my turbo (hx35w)??? Different wheel or what???

The DSM guys get those housings out of convenience I think. Sticking with the stock 12cm2 twin scroll will be more efficient, and if you need a larger one, well I believe you can get a 16cm2 housing for your HX35, and still retain the twin scroll

I was running a HX35/40 hybrid with the smaller 8 blade HX40 compressor wheel before. I think I was close to 500rwhp, but maybe a bit short. I only had a 38mm wastegate though and I think my ex manifold pressure was so high I was pushing the turbo into choke hurting my power. Also, as I mentioned, it was the smaller compressor wheel. No dyno on the island here, but I was ticking off 122mph trap speeds in a 3100lb car + driver with a **** ton of wheel spin.

You could always get the HX35 now, then do the hybrid later after you start wanting more power (don't we always )

Holsets are Internally gated stock right.
I ported out the T3 hole when i used mine.
But Due to the ATP WG flapper I could only do about 28mm.
I wanted to leave a little room around the port so the flapper could seal.

yea, i'm hunting for 125+ traps...but not that much more...My car weighed 3100 w/ me in it, so that is a good basis for me as well. Was that with the stock ex. mani? Sounds like I need to do some investigating into this hybrid and maybe put it to work :D

what kind of supporting mods would i need to be in the 480-520whp range? are cam upgrades necessary?

and Cjmartz2k how did you like that T04e on your rb25? thats actually what i have right now waiting to get installed. im going to be getting some 650cc injectors to go with it. my goal was to be at around 380whp. am i hoping for too much?
