im pretty sure if you get a 6blade hx40, that might make your goal as its a 69lb min turbo.

Not sure if i should go with a precision 6152 ball bearing or holset hx52. All this will be e85 with 1000 or 1300cc DS injectors. Thanks all for you assistance If anyone wants to email me at teamelim@yahoo.com please do so. I actually put the order for the precision Turbo but I have till Monday morning to cancel and get the holder.
If you've already researched the Precision, I'd stick with it.

You'll prob need bigger injectors once you start shooting for 600whp

if hes trying to shoot for 600, then hes going to need something way larger than a 6152. that turbine is too small. he might have to go with a BB 6765 if hes going to really hit 600whp. and on e85. theres a lot of factors you have to consider when your aiming for that high of HP. he can use 1300s, but his fuel pressure has to be sky high for it to work. i.e his basepressure would have to be 60psi minimum.

Holset update!!!!!!!!!!!!!!

I have my rotated kit installed as well as my reversed LGT intake. The car is running but I'm still working out a few bugs. I should be able to post up some data very soon.

in the process of gathering everything i need for a he351ve swap, what is recommended for EM? could i do it with my stock ecu? or should i go blow through and get at least a piggyback unit? sorry not very familiar with the tuning side of building cars, more with the building and fabricating. is there anyone will to let me shoot them some pm's to pick their brain with questions about problems they ran into, etc?

thanks for any and all help, this thread has been a great source of info

A 6262 is more than enough for 600 awhp

depending on boost level and fueling my dude, but on pump gas, not really ( for subarus ), evo's, another area, but I dont think ive seen a 6262 make 600 on pump gas. usually it takes a lot on e85 to make that happen like (27-30 psi id say) just from experience. The new 6466 looks beast though. but thats off subject, hows everyones Holset mockup, fabs going. i forgot how physically large this turbo was so mockup is taking atad longer to do.

I agree with you there, e85 would definetely be needed.

HOW COME NO ONE IN THIS THREAD HAS BEEN TUNED YET!!>!!>>! also the mixed results come from which holset you get, since there are a total of 6 versions for the "HX" series. so some flow better than others so they will produce more power, but thats all relevant to the fuel, engine displacement, ports, cams, etc etc....so they should still produce about 400whp+ on 21+psi.

Page 1 post 11. Your numbers look right on. I had suspesions about my crap boost gauge so I just checked a bunch of logs and they are never showing me breaking 22psi. So airboy puts me just a tad over 420 at 22 psi. This is a stock motor, 255lph, and 910cc's maxed out.

Just went through my fuel system with -8 sending, aeromotive rails, -6 return, and a 400lph. Got some 1650's standing-by but not tempting fate with the stock motor as Im pretty sure I have already started lifting the heads. Did a EL header and built a revised/improved (321) up-pipe while I was at it; yea up-pipe mock-up takes forever..... Getting motor parts together now and Ill be pushing the built motor to 30+ on the 351. I hope to find out what this thing can realy do pretty soon.

the reason is most people doing Holsets are DIY'ers like myself and are ongoing/never-ending projects. mine is self tuned and never been on a dyno. airboy shows consistently in the 380's on nearly maxed out modded injectors & 18 lbs of boost.

i was using a UTEC for speed density tuning for a while but really didnt like it. very crude and a pain to tune. seemed like the ecu was fighting what the UTEC was trying to do?

now im back on a stock ecu with a 32bit Speed density rom thanks to the guys over on Rom Raider forums. its dialed in perfectly, but still only on 18lbs and still needing bigger injectors. prolly going with a set of 1200's very soon, iv just been lazy recently. but im hoping to get on the Dyno @ OCAWD meet in June.


like albersondh im also looking into building the motor. most likely a long rod build this fall/winter so i can rev it out to 8K+. so im not trying to make any huge numbers right now because its inevitable whats going to happen. im just trying to get it through another summer with a set of heads and a block that are still re-buildable

PS: im still on a OEM clutch with near 60K

this is true. i am also not tuned as well and i had to DIY my whole turbo kit to get this DAMN TURBO TO FFIT!!!! the adapter flange and the downpipe. i just got a set of 1000s, so i might trade those and another set of stock modded 860s for some bigger injectors. my motor is a 2.1l though and its ready to spin 9,000, just need the fueling to back it up. but just as you, i am not looking for large power, just a nice long powerband haha. Im also on the carberry SD rom, thanks to the many people on romraider your lucky you have a 32bit ecu considering you have options. us 16bit people have it worse haha. but im also at a standstill like you guys as my stock 5speed has 200k on it but still going strong. hopefully the recent plate i just purchased and the fact i have a lower displacement motor (thus less trq) will keep the tranny alive at least until it gets off the dyno :/ but yes i agree, its a never ending story. but hopefully by the end of may, my car will be on a dyno

My tranny dramas; I busted my OE 5mt, rebuilt it, then sourced a 07 6mt and R180. So all that is installed now, one less thing to worry about......

SD for 32-bit?!?!? Last time I was on RR it was in the works but man that happened wayyy faster than I thought it would. I figured AEM would release for 08+ before we got open source SD.

John how is the SD working out for you? Any noticable drivability issues? Seems like a lot of my drivability issues can be attributed to my MAF or lack of enough time fine tuning the scaling. I did not/do not tune for reference but I need to start.....

Nice to see some activity on this thread

I'm self tuning this time and I am taking my time. Really just trying to get my fueling back in check. I turned up the boost on Tuesday and the car feels good. With the .63 housing I am seeing 17/18 by 4000 rpms and 21 by 4200...... 3rd.

I'm headed out to do a few more data logs, I'll post a dyno plot soon.

yea im surprised as well, i had been trolling over their for a while then got fed up with the Utec. so i started talking to TD-D and Merp. luckily Merp had just finished the code for his 06-07sti and TD-D was already porting it to his car 08 edm STI, once he finished his i send him my rom and we went back and forth for a couple days finding all the needed ram holes and such then he sent me a finished rom & definitions. ran if for a few weeks no problem then got in contact with merp and sent him everything TD-D had done he added in all of his new code plus NSFW patches

now we have a 08+ WRX 32bit SD rom with LC/FFS and CEL flash for knock. and ignition Cut coming very soon im told

but dont get me wrong their was some scary times where i thought i had bricked the ecu, because i would flash and then car wouldn't start and you could here the ecu clicking

also merp made a spreadsheet to make it easy to tune. it helps convert your MAF to VE to help setup a general VE table for first start up. then you can log ve and wideband and it will make adjustments to the VE table based on AFR.
