Best Turbo? [Merged 9-9] turbocharger upgrade

[hukster00]

hi, i wona upgrade my turbo on the gsx, and there is so many choices dont know which one to buy, so i asking you pepz wich turbo is best for under 1k for street/strip setup thanks,

HX40's full potential is in the range of 50-60 lbs of boost, does that mean it doesn't make sense to run it on any DSM?

 

[dsmcurse]

i think any of these turbos you named would be fine. all of the expensive big dog turbos get the job done. they are all so competitively matched that the difference performance would be pretty minute. i would recomend hx40. and im not saying that because i own one. the hole set turbo is built very tuff. these suckers can really take a beating. im quoting a guy that said "the hole-set turbo was designed to be over worked and under paid" i know a guy that had a 60trim and lost a race to a guy running a 14b! no joke. throw all the big expensive parts you can afford at the car and it wont necessarily make you fast. ITS ALL IN THE TUNING.

Exactly why I personally don't like Holset turbos.

personally i would go with a Garrett 35-82 u gotta have something to look forward to later in the rpms who wants the car to fall flat on its face at 8000

Better yet, a GT3082R (AKA: GT3040, FP3065). I also hear FP makes an HTA version that will blow your mind. Think the 35R's HTA 82 comp wheel attached to a 30R turbine wheel in your choice of T3 or the FP .68A/R turbine housing. Would be an absolute BEAST on a 2.3 motor.

So after much consideration and thinking I decided that I'd rather have a 'bolt on' turbo than having to invest the money to make the HX35 functional. I think Im going to keep the HX for future use but not at the moment.

I want to get your opinions on what the best turbo, other than the EVO 3 16G, is that bolts up to a Mitsu manifold and a Mitsu O2 housing (meaning I get to keep the same downpipe). Also, that is internally gated. I know these are many instances and I think this only leaves the 20G and 18G up in the ball park. Anybody have any other suggestions?

Thanks for the space.

If you have a 2G a T28 is a nice option to consider also.

 

[jjgrizz73]

Most will probably say the 20g turbo since the 18g doesn't really run that well. My PTE 50Trim is also a bolt on turbo and runs great so theres another option for you, but for the price of one of these you can probably buy a holset BEP housing with install kit and run the HX35 if you really wanted to.

 

[jjrock5]

Ive had the FPT28, very nice turbo but Im ready to step up to something bigger.

 

[1997_GSX]

I have the PTE 3231R Dual BB 54Trim and love it. Full spool with stock head and cams is around 3700

What do you mean about the 18G doesnt work well? I heard that this turbo has better potential in the high boost range than the E3.

I don't undestand why the compressor map going to 50psi is a bad thing either

It's not like the map doesnt show efficiency at lower boost and lower airflows. MWE really is a good thing. And very large compressor exducers help alot. As well, it's not like the hx40 hasn't made good numbers at under 35psi. Look at the Holset Results Thread, stock 7.8CR and stock intake manifolds doing quite well with the hx40. Tuner shops make big power with lower boost with their turbos they vend because of high compression, rpms, and big flow boltons.

the s259 is just as big as hx40 (in the map too). And the gt30r varients spool the same and flow less. One of the most balanced turbos on the market is the fp3052/gt3076r. I think the suggestion for the hx40 over that turbo is because they both spool about the same. Why not have the turbo with more flow and get a better deal on the cost. . . And for the OP's goal? I don't see a bolton 30r varient making 500whp on pumpgas. . .

. . . Back to the gt35r being laggy. It's going to be more laggy than the other turbos mentioned. But still, with a stroker, it won't be bad at all. It's just at a different level of cost than some of the others mentioned.

For the cost of an upgrade to an 18g over a E3 would not be worth it. In other words, if you are thinking 18g or 20g go right for the 20g. I say buy the BEP holset housing and run the HX35 and then when you decide to go T3 just switch the exhaust side and your manifold

I'm liking the EVO3 16g myself. Nice little 60 h.p. jump over the T28. Same spool, much more topend power. There were times there last winter that I actually scared myself coming on boost, the torque steer in my AWD was that bad. I can get completely sideways coming on boost in 2nd gear in the rain. When you can scare yourself in your own ride, that's impressive. I can't even imagine what its going to be like when I drop my Kelford 272 cams. I say step to a the 16g, buy it for say $500 at worst, then when your tired of it sell it for $375. Practicall a no-brainer.

 

[jjrock5]

Well Im going to upgrade from a T25. And I did the math amd in order for me to get the HX runnning, including, FP mani, DSM housing, recirc 38mm o2 housing, 255 pump and afpr it came out to ~$1500. So Im looking for a better alternative to this...but not considering the E3 as an option, I need something bigger.

As much as I dont want to say it, the E3 may be an option.

Oh ok I gotcha. Even if you hop to the E3 you need to really upgrade some stuff in order to run it to the full potential. Im not sure if you ever have been in an EvoIII car but its substantialy quicker than the stock T25. Upgrading to a 20g with no fuel pump, afpr, etc isnt going to make you much quicker than a E3 because it wont be using its potential...plus slower spool

ill put it this way...my tuned EvoIII wasn't much slower than my 50trim(untuned) at the same pressures.

 

[jjrock5]

I fully understand what youre saying. Ive been in a 2g awd with an E3 but with little to no support and my GST FPT28 could spank it. But I guess as you guys are saying, this turbo has much potential...

 

[jjgrizz73]

Some guys have broken the 400+whp mark with an EvoIII so yes it has much potential not to mention amazing spool time...theres soimetimes when I wish I had mine back to throw on every once in awhile.

 

[95GreenGSX]

I know people that run high 11s with a e316g. Ive seen much lower times too. It all depends on what you want and how much power you want to put down. If I wasnt already this far into my HX40 I would have went gt30r, its smaller and a great street turbo.

Yeah but Im almost positive thats with some type of fuel other than 93 (which is all Im going to use) and some crazy boost numbers which my car will probably never see.

My buddy has 30R in his golf and he likes it but not really considering it for my purposes.

 

[clarson_75]

you should be upgrading your fuel and air flow before you jump into a new turbo. if you aren't looking at anything smaller then an e316g you are going to hit fuel cut early and often. then you will be replacing a motor as well!

Meh, I have FIC 850s and ordered 255 a few days ago, AFPR will probably br ordered at the same time as the turbo and Link V3 with Eprom is still sitting nice and new in my room. I think that pretty much covers my fuel(for now). Now back to turbo talk, I just started looking at these BB or journal PTE turbos, not too shabby from what Ive read. Anybody have a particular preference to the BOLT ON ones? Looking for 450whp (at some point in the future, just looking for the turbo that will do the trick, bolt on remember!!)

 

[v8s_are_slow]

I know I can vouch for the E16g. My car was pretty gutted but ran very well on minimal mods. Was on a fwd car though so got rid of it cause traction (even at 100mph) on the street was a joke. Had a fmic, 550cc injectors, Walbro pump, K&N, GM maf and translator, boost gauge and wideband, gutted car, and that was basically it for mods. Ran a 7.797 in the 1/8th. That's about an 11.9-12.0 in the 1/4. Not bad for very few mods.

If I was gonna go with anything bigger than an E16g, I'd go external gate. Plus too, you should keep in mind that the bigger you go, the more boost you need to run for it to be in it's "fun" range and the higher the octane as well. Just because a turbo is small, doesn't mean you can't go fast on it and make it go very fast as well. If you're only running 93 octane, an E16g is great at 20psi on the street and well into it's efficiency range to where it can be felt and to have fun in.

 

[jjrock5]

Good thoughts, thanks. It's something to keep in mind. Did you have ANY port work?

 

[VETTE_50_TH]

John, follow my upgrades. You've been in my build blog. Do a standard Td05h 20g. I've talked to so many people, and this turbo will support an easy 400 on pump with a 190 pump and 750 injectors.
