Holset turbos

[Reno]

Your trying to make 550hp on a CA18?!?! Wow. Double wow on hoping for good spool. If I were you, I'd get the 7 blade HX35, get close'ish to that number and have something still streetable. Your not going to have a quick spooling 550hp turbo on a 1.8L 4 banger. It's just the nature of trying to make big power on a small motor.

RB24D--I'll email you when I get home.

for that i believe a holset hx40 with a sr20 full race manifold(ca18 flanges welded) might be there and if memory serves me correctly i'd suspect full boost @ roughlty 20 psi would probably be in the 4200 range.

[Cjmartz2k]

I think a HX35/40 hybrid would be best for him, but if it's a straight drag car, I guess a full HX40 wouldn't be to bad.

Hey Matt, I sent you an email with the pics of the 8 blade (smaller) HX35 compressor and housing.

[SuicidnS13]

How much whp can the hx40 support? Say on a 2jz? Or an Rb25/1jz?

[Cjmartz2k]

BALLPARK 700hp at the motor. I think a little less, but the DSM guys say more. They have 650awhp dyno sheets. I guess it's a matter of what dyno. They are running easy 10's at mid to high 130mph trap speeds in full weight awd cars though, so that's a lot of mph to back up that dyno sheet. I think I'm mid 600's at the motor now, but I'm only running like 25 psi. These things love boost and the DSM guys run them at over 2 bar on C16 race gas to get the big numbers. I'm going to look into water/meth injection soon to try and up the boost.

Keep in mind there are a couple of different HX40 compressors BTW. The 8 blade's supposedly don't flow NEAR as much as 6/7 blades.

what dsm guys exactly? im not familiar with their motors, are we talking about 3.0 liter engines also?

I dont know much, but im assuming, that they also give up some of that torque from the all wheel drive.

We are talking about the infamous 4g63 engine (2ltr) which won the castrol super tuner shootout. Its found in Evo's, eclipses and many many more platforms.

[Kalypso]

oh... yeah the 4g is established

But I didn't know the shootout was over, I stopped following it. I entered the contest for the chance to win an rb26

... back to holsets,

if anyone has links for a manifold fabrication thread/article, preferrably tubular style I'd be grateful. I think thats what we all need right now.

How about 6boost??? Ive got one and love it. Looks amazing and im expecting great results. Not sure if this is what youre looking for but its my contribution.

[Kalypso]

No I want to make my own... and I'd like to learn how.

6boost is 1000, a tig welder and good tubing would be 350-400 total, for a nice manifold...

this is pretty f*ckin useful. http://autospeed.com/cms/A_2605/article.html

Where in the world are you buying manifold materials AND a tig welder for that much money? I'll buy 7 lol!

I'm a really big fan of doing things myself, I've done everything on my car myself. I planned on making my own manifold as well, but when it came down to the 6 boost manifold group buy, I'm really glad I took advantage of it. Maybe MAYBE I could have bought a crappy welder and materials for the $800-900 I spent on the 6 boost, but it would not be NEARLY as clean, dyno tested, durable, beautiful, warrantied, not to mention the time I'd invest in it. My time is worth a lot. Rarely will I do work on cars for people on my days off, and I sure as hell wont even consider it if I'm making less than $100 for a few hours work. My free time is worth too much to be fabricating when my entire week is spent on cars as well.

I understand a lot of people dont have the same career as I do, in which case, if you'd like to learn some about manifold design, I highly recommend Forced Induction Performance Tuning, By Graham Bell. Great book! Good luck-Max

[Kalypso]

correction... electric welder

thanks for the BOOK!!! I will be reading that.

[toadx8u]

dude ima tell you right now your off your effin rocker if you think your gonna make something as good as the 6boost mani....im sure the welder your lookin at on ebay is a gasless wire welder and your retarded if you think your gonna weld anything with that...to get the quality welder you would need to match kyles welds you would have to spend a min of 2500 on just the welder...then your gonna need years of practice to match his beautiful welds...oh then the 1000s of hrs of RnD that he spent figuring out what works the best...i showed my mani to some friends of mine that build racecars and asked them how much they would charge to build a similar mani with the same pipe...and their price was very close to that of full race...and when i told them i paid 725 shipped from australia their jaw about hit the floor...so as for you building your own...just go buy a ssac if you wanna be cheep or spend the doe and buy a 6boost mani...

sorry that was way off topic...when i come home from iraq in 2010 ill be buying another 6boost mani for my RB26 project and attaching a holset hx55...i cant wait to see kyles reaction when i ask for a T6 divided flange...

Dread stop smokin the sensi

A decent entry level tig welder is about $1200, not including the tank. Hell my Lincoln mig welder was more than $400 from HD with no tank and it still cost me about $150 just to make my down pipe.

[Kalypso]

i shouldnt quote myself but...

correction... electric welder

thanks for the BOOK!!! I will be reading that.

you can still do a lot with an electric welder.

[eh?]

Regardless you're still looking at about $800 to make that manifold with a decent mig welder. Not to mention if you're new to welding the manifold is gonna look like poo...

[toadx8u]

this is true i can do alot with a electric welder but can you? now what kind are you talkin about since almost all welding requires electric and that article you have is ok but the manis that guy makes are junk...im good with a stick and a mig and idk if you have ever welded b4 but its not something you can just do the 1st time and get it right it takes years of practice to learn the speed and techniques that it takes to make a quality welds with a buzz box...theres no method to his build other then to weld some tubes together and put a turbo flange on there....trust me for all the headache and failure u will have its more worth your time and money just to purchase a quality mani like the 6boost one...i could understand you wanting to weld a cage in or some other DIY metal work but its just more cost efficient to buy a quality product...

[Kalypso]

I guess I'll just have to try

[yotik]

+1 Ive had the honor to fiddle with tig, mig, fig ( ) and arc welding and its no joke. i suck balls at it. it takes lots of practice. my advice is if you really want to learn how to weld go to school or learn from a pro. otherwise good luck...

is it just me or have the final price of holsets gone up on ebay

[DriftingisLame]

I lurked around on ebay for about a month or two before I had the cash to buy one. I used to see them go for around $250-$350. I ended up not seeing them go for less than $350-$450 in the last couple weeks, I ended up paying $420 for mine. I was kind of pissed but glad I got it when I did, it was supposedly "rebuilt" and never used since.

[db_s13]

Ive been having a little trouble on choosing a turbo for my rb20 and is between a garrett t3/t4 60 trim with .63ar and the holset hy35... i have all the supporting mods and with be tuned with nistune on E85 and want to run a max of 18-20psi and hit in the 350-400whp range and is driven daily and time to time weekend drag....just looking for a lil but of insight from everyone and i kno the hy35 loves loads of boost but can get one cheap thanks

[Cjmartz2k]

I seriously doubt your going to make 400rwhp on a T3/TO4e, but the HY35 could make that with out to much sweat. Why are you limiting yourself to 18-20 psi just curious? Is that on a specific turbo or something? Boost levels don't pop motors/headgaskets, high cylinder pressure (knock or high hp) does. What's a 10 psi difference when you are talking about cylinder pressures in the hundreds if not thousands of psi?

N/M

[db_s13]

not really limiting myself to 20psi but im going to learn to tune and thats just the range that i will feel most confortable with and still make good power with

[ANVIL]

I know for sure a T3/T04e can make north of 400whp on an rb25. I imagine it would be super laggy on a 20 though.

Evan

thats real good to hear because thats the turbo i have and im hoping your injectors will get me to my goal of 400whp.

[BoostFab]

i don't think the t3/T04e to be laggy on the rb20 at all.

[toadx8u]

bump bumpity bump bump.....bump bump

time to talk about this again....lol

[Sil240]

A T3/To4E 60 Trim can def make 400hp plus.

But... with the laggyness depends what Turbine a/r he's rockin.

I have a .82 A/R and mine is pretty laggy.

For the 20 I mapped out the 50 trim with a .63 A/R would be better. (for me at least)

[Cjmartz2k]

A T3/T04e is a WAY different animal than a TO4e me thinks. Former should be well suited to an RB20 as boostfed stated. Should be a fall into a slot under the HX35 somewhere size/power wise. I had a TO4e with a .84 a/r and a Q trim wheel. That thing was laggy as s*** and didn't make a ton of power. I think that's why I fell so in love with holsets is I came from that laggy, underperforming thing.

[PorkChopExpress]

where do you get the special banjo bolt to use the stock oil line? what size bolts to block off the water lines?
