as the title states i am looking into a turbo upgrade i am looking at a gt30 with Mitsubishi housing or a fp green or a 50 trim.. i have a galant vr4 my setup is
.03 over block
crower rods
ross 9.0 pistons
1mm over valves
hks 272/280 cams
9lb fly wheel act 2600 clutch
740cc injectors
cooling mist 50/50 meth
dsm link
buscher racing fromt mount
thats just the basics

i just got this car running i am looking to break 11.6 on 20-23 psi and 11.1 on 27-30 psi i have been tunning for years just new to the dsm crowd.. my question is what turbo would suit my needs i here so much good about the fp green turbo.. and the gt30.. i know i need a tranny upgrade but that will come as soon as it blows lol. so lets get some opinions on turbo size. and how much hp will it take to reach my goals. i do have the driver mod 1.603 60ft old street tire 14b turbo 20psi 3 bolt no 2step.. any and all info is appreciated

FP3065 is a mitsu flanged gt30. That would be a good turbo for the goal. Ohh... and get some bigger injectors....

Go with the FP3052. Brian runs consistent low 11's with his on a full weight car using E85. I also have the same turbo, but haven't been to the track in a couple of years. I went from an FPgreen to the 3052 and love it. The FPgreen was great also, but the 3052 spools a bit better and puts out a tad more airflow.

Well... I'd agree with you, that's the turbo I'm probably going to get. But I was thinking if he wanted any chance at running those times with just the piss 91oct gas he might come closer with the 3065. I don't have any info to back that up, but running e85 lets Brian run the mad high psi.

If he got the 3052 he'd probably want to get some meth injection. I don't think e85 is abundant in Cali.

He also said he wanted to run low 11's at 28ish psi, which means racegas/meth/e85 anyway, hence my suggestion.

if you look in my list i have meth... and for e85 there was none i cali besides one in la 300+ miles away, they just opened a second one 5 miles from my house .. how much power dose it take for a galant to break 10.999 i was thinking 460ish with some weight reduction? and i kinda did not wanna go fp3052 since ill need there expencive 02 housing and downpipe... but its a option. any one have a list of bolt on turbos that will put a galant deep into 11's around there max efficiency?

You're going to need to be in the 500-550whp range to get the car to go 11 flat. I'm not sure what kind of cars you're used to racing but these cars are heavy, shaped like a brick, and their suspension is far from ideal for drag racing. If you look HERE an FP Red will get you there but technology has come a long way since that turbo was designed, I'm sure there are better choices out there now. I don't think a 50 trim will get you there though.

It uses the same downpipe that any other turbo would use. The only extra thing you would need is the v-band o2 housing. It's expensive, but it's a nice piece. Even if you get an FPgreen, I would suggest an external wastegate, which means you're going to need some type of o2 housing to mount it on as well. Unless you do a manifold mounted wastegate.

FP3052. What can I say. [email protected] at 28-30psi. I also have best trap of 131.55mph. Car also runs 11.6-11.7 at 120mph on 23psi. The Green and a 50trim are great turbos but they are getting old. fp3065 is a good chose to with only giving up a little bit in the bottom and mid range to the 3052. I realy feel that the GT30R and the gt35r are the best turbos for a dsm or galant.

Alright. I fail for making quick reply and not reading your mod list closely. As for the Holsets... they flow like crazy, cheaper in comparison, probably cheaper to rebuild (maybe). I don't know how the fitment would be though. Might need to do something with the radiator etc.

Here is my thing with the holset turbos. You don't see on listed there. You see lots of other turbos just no holsets. You would think after being around for more than 5 years you would have a holset on that list.
I pick turbos off what has been proven to work time and time again. I played the whole game of trying the mutt turbos when they came out. That ended up bitting me in the ass big time. And just so you know the same people that make the housing the the Holsets are the same ones that made the Mutt. Same people that have fucked a lot of good people in the dsm world. Just some food for thought.

well i think the holset option are for guys like me who are not able to afford those $1,xxx turbo's. I just purchased a used hx35 7 blade that's suppose to flow around 60 lbs/m and has been proven (according to the dsmtuners) to spool faster than the evo16g. Im also going to use the BEP bolt on mitsu housing and with that combination, it's rated to reach 500whp with supporting mods. For those who want more power, they go with the hx40.

It has also been proven that these holsets are way durable than any aftermarket turbo's out there. good for 500,000 miles!

for the cost of the used holset, the BEP housing, and rebuilding the turbo i purchased, im just shelling out around $700. Some even lower! much lower!

i'll definitely post a review once im done with my long block rebuild. but thats probably 1st quarter 2009 as im still purchasing stuff on my parts list.

bottom line..for the price, the power, and the durability, nothing beats the holset route. Ive done so much research in the last 8 months on which turbo to buy, ended up with the holset because of the factors that i mentioned above.

how does a turbo spool faster than a much, much smaller turbo and yet still flow so much more? does it defy the laws of physics? is there special alien voodoo in the BEP housing?

I'm not defending the Holset because I have no experience with it, but some of our proven turbos are pretty old design compared to the more advanced designs available that improve spool and flow such as the difference in the new HTA designs. Although I have the same questions how the hx35 spools like a evo316g/18g from the accounts I've read.

Over on tuners theres 4 huge threads about the Holset's.
Theres I think but i havent found Proof that they do spool stupid fast how i have no clue and they make big power how onece again prob that vodoo magic lol. But they are bricks there heavy and are built to last.
I plan on going with a HX 35-40 with a mistu houseing. Brand new you can find them for under 1k.
Hell of a deal.

Take a look at the FP 30R-HTA. It is basically the best of all worlds. With the FP housing it is bolt on but yet better air flow than a mits housing. It is HTA so you will see improved spool over a normal 30r. Not to mention it has FP's known reliability and longevity. I think it is a .63ar and should flow high 50's for lb/min.

I just read all for parts on tuners and all I see is people not making the power they want on the hx35. So they go to the hx35/40,still not what they wanted to it hx40time. Oh guess what still not what they are looking for. Now what? Well its hx52time. Some on posted a vid of a car with a hx52 at 26psi on a fwd dyno that only made 530fwhp. Sorry but that is gay.
You say the FP stuff is to much. Well just think how much money you will have after you keep swapping out holset turbos for bigger holset turbos. What I have learned over the years is to go with what has been proven to work time and time again. FP,full gerrett. Those are the two most used names out there.
Don't get me wrong. I think that holset is a great turbo. Hell I play with them every day at work. I just don't think they work well for are application. But if you still really want to run one. Then best of luck to you.

Loved my GT-35, garrett, ball bearing, choked down it spools well. All out with a big housing it pushes 65 lbs/min near 600 wheel. My 3071 Garret fully pissed only eeks out 440, but spools like a 16G. my thoughts...

I'm loathe to say too much at this stage because my Holset still isn't on and I want some real life data to publish when I've done this to hopefully help settle the speculation that has been going on for what seems like forever.

I think one issue though is that track times are used as a benchmark. If you look at Holsets with the BEP housings it seems obvious to me that they are deliberately choked. That to me seems to be the only way to get such a big turbo to spool as quickly as they do. But at the track 400-800 rpms of lag is acceptable to get the higher flow required at 8500-10,500 rpms where really fast cars make power. Speed is also a factor of rpms as well as gearing so making max whp in that rev band is important at the track. On a street car hitting max power at 7000 rpms and having power tail off after that might not really matter.

The other thing about spool up is that I think BB turbos faster spool up is related more to the restrictors that come on them as standard than the BB centre housing. I'm pretty sure Curtis told me that some ran tests using restrictors on journal bearing turbos and the restrictor brought the journal bearing turbo spool time down to within 100-200 rpms of the BB turbo when pre-restrictor it had been about 800 rpms shy.

I think the Holsets offer huge potential as great street turbos, especially on strokers. I have doubts of their potential at the track and that seems to be proven by Brian's posts above.

I'm really interested to know how the HX Pro 40 or Super 40 compares in spool up to the HX 35/40.



Getting old sucks ... but it sure beats the alternative !!!

well the reason why they're only getting 500fwhp from the holsets is because the car is FWD. make it an AWD and they'd shoot for 600++whp.

And as ive said these holsets are for budget conscious people like me who are for powerful and durable turbo's. As for spool time, yes the hx35 with the BEP housing has been proven to hit 20psi at around 3500ish. Try to send Pm's to those who are posting. sometimes they dont post on the thread what their latest runs are after further fine tuning.

As for durability, i dont think no one can question the holsets. for maintenance and parts. dirt cheap!

I aslo dont have first experience yet with these holsets but i bit the bullet and bought an hx35 and a BEP housing. it's currently on the way to a turbo rebuilder before it gets shipped here in the Philippines.

Once my engine rebuild is done, i will post dyno numbers. Im just aiming for 400fwhp coz i just use the car on the streets not on the track. but on paper, this combo of the hx35 with a 7 blade compressor, mated with the BEP bolt on mitsu housing, is comparable to an FP red at half the price.

Cheeky,

i suggest you go with the straight hx40 and not the hx34/40 combo. The turbine side way outflows your compressor. There's a BEP housing for hx40 also available from BEP directly. It's cast stainless steel as well. or if you want, just use the stock divided housing and run a divided manifold. im not sure if the hx40 is a t4 or t3. but most probably it's a t4.

ummmmm.. I thought that running FWD will increase the power rating on the dyno...
you've got a greater loss of efficiency due to the AWD drivetrain...

ie. FWD 500hp, AWD 450hp, RWD 475hp.... (just an example)

I have a GT3082r, I'm making about 450hp at the wheels on pump
550hp on race gas... stock intake manifold ( we would have made more with the JMF)..

The GT30 spools like a small turbo on the 2.3L stroker...
Hasn't failed me yet!
