I have a gt35r on my evo 8 its maxed out at 38psi making 600whp.


what options do I have to upgrade it or beef it up?


theres a HTA upgrade? im not to clear on still researching.


can I bolt up a bigger ex housing anyone make one?


can it be mated to like a 40r hot side ?


any input id appreciated it. I don't know a lot about turbos.

 

If you're having to run 38psi to make 600 there are other restrictions. Tell us more about your setup

 

made 460/388 on pump gas
591/490 on q16 maxing out the turbo


mods are
wiseco 9:1
eagle rods
gsc stg 2
supertech valvetrain
aem cam gears
map rev2 manifold 70mm flange
70mm full blown tb
spoolin cop
ets 3582 bottom mount
tial 44mm
2.5" o2 down pipe section to clear ac comp
3" right after to buschur 3" exhaust
2.5" ets intercooler piping
ebay 4" core intercooler
3" outlets
shep stage 2 t case with quife lsd
stock evo 8 trans
unknown single disk clutch by previous owner

 

Send the turbo to fp for the htagt3586r compressor wheel upgrade. The new wheel will make your turbo good for 750whp with very little slower spool. Or have the htagt3582r upgrade which will spool faster than your standard gt3582r and it will be good for about 700whp.

 

You have a bottleneck somewhere. The o2 housing isn't helping for one. The eBay FMIC isn't helping either. You may also want to find another tuner. Check your cam gears and make sure they are timed correctly. Your clutch may not be holding the power either. What is your fuel setup? You don't have that listed.

 

Amazing that single disk held that much power!

 

Wont a tial Housing help also

 

460 on pump gas @ 38psi something is not right, I have a 35r on my 9 and made 390 on pump @ 22 psi, and this was read on a mustang dyno

 

Hes saying 591 @38 psi. I made that on my old 35r setup at 33psi with low timing and less efficient cams.

As we've said in this thread, you have a restriction somewhere or cam timing is off or some other variable. You're tuner should have picked up on that and not ran the boost so high. Need to step back to basics.

Evaluate the health of your motor, check timing, etc. Then continue down the line.

 

the timing was dead one. before and during the tuning. we advanced the intake came 2degrees and 4 degrees with no change or it lost power.
so was put back to zero.


the clutch held there was no slipping or any spike or drop in power that we noticed on the dyno. or anything weird or over revs. but that's besides the point its done now after some launching.


the fuel setup is a walbro 400 in tank with 8 gauge wire stock feed and return lines
to a bosch 044 pump in the engine bay with aem fuel rail -6 lines and fic 1450s.


idc on pump gas was 60 percent and on race gas 80 percent.
im going to do the 8 an feed and use stock feed as return.


any one know the fitting needed at the fuel hanger to get -8an adapter on
and to to use the old fees as return at the fuel hanger?

 

the o2 housing piece nothing can be done there without changing the exhaust housing to a vband so I have room to make the 90 or remove the ac comp.


but more than like likely I want to get a top mount kit. easier to make a 3" nice downpipe or if im swapping the turbo I will get it with v band and make a new 3" vband 02 piece.


also been thinking of making 3" charge piping with tial 50mm bov and new intercooler.


any one use treadstone 850hp rated intercoolers on evos. ive used them on Hondas wit no problems. haven't seen anyone use them on evo?

 

You keep saying your turbo is maxed out, that really is not the case... There must be a bottleneck holding you back somewhere. Most people with the same turbo are 650-700 before they are maxed. My guess would be Ebay FMIC and possibly cam timing. Power should've changed when you go from 0 to 2* and 4*. Either up or down, but it should've changed.

 

did lose power adjusting the cams,


timing is dead on. looking up the specs on garrets site says 3582r max hp is 600 and 2 others say 675. mine is a regular non hta or anything.
so either way im just going to be upgrading the turbo for my goals.
with the new turbo going to get a 3" vband discharge to make room for a 3" o2 downpipe section.


just ordered
comp twin disk
tial 50mm bov .
goin with 3" charge piping




now im looking for
treadstone and or ets intercooler
and a t3 ball bearing 6466.


or if I sell my whole kit. will get a sheepey top mount 6466 kit.


how much significant spool difference between the journal and ball bearing 6466? 500rpms? 1000rpms?

 

I made 613 at only 27psi on my FP HTA3582r with .82 v-band TiAL turbine housing with E85 and that was only scratching the surface of potential with that turbo. There's probably another 100+ hp sitting in my setup. My fuel pump setup as it sits was closed to maxed out so they stopped at 613. I'd imagine, like has been said, bottleneck somewhere because you should be making more power at a lot less psi.

 

yes you are at 613whp on a hta 35r


mine is at 591 with just a regular non hta 35r.




but I am working on upgrading few things.
just got a ets 3.5 " intercooler


just trying to figure out if I can upgrade my turbo to hta 3586 or hta 3582r only? and is it worth the $700 for how much more power?
