i got a 95 elantra with a 2.0 eclipse engine i want to upgrade it to a turbo in the future and i need to know whats the biggest turbo i can run on the street with minimal lag

There are many choices, I will give you some Turbonetics exmaples to think about.

What I personally would run on the car would make it exrtremely powerful and be able to achieve a 1/4 mile time that would enter into the 12's... ! Thats the high side, the downside is that you will need to spend alot of money to upgrade alot of components to be able to run this setup reliably!

I would suggest going the T3/T4 hybrid route with a little spice to it <img src=/images/forums/snitz/smile.gif width=15 height=15 border=0>

T3/T4 with .63 turbine housing with a Stage 5 wheel, water cooled center core, 360 degree thrust bearing, AR70 compressor housing with a TS04 compressor wheel!

There might be some machining involved in getting the TS04 comp wheel to fit into the housing, but I'm sure Turbonetics will do this for you!

Your boost responce shouldn't be much more than 3500RPM and full boost at about 4000RPM (thats when the fireworks start happening!

For this setup you will have to upgrade rods, pistons, G/box, drive train, valve springs and guides, etc

This will certainly cost you alot of money, but if you want the power, you have to go all the way (Do the job properly!)

Hmm... this setup would need Mad Money (TM)

Let's talk about a "normal" turbo setup. UFB, would you go with a T3? What's nice about it is that it can be later upgraded to the nice T3/T4 you were talking about Properly tuned, a T3 can produce 250-300hp on a Beta (dunno the numbers for a Mitsu tho). That's still pretty much fun to drive, eh!

i was thinking more along the lines of a mitsu turbo maybe a 20g

Why would you want a Mitsu turbo? A 20G is more expensive than T3 or even a T3/T04 hybrid. The bolt pattern needed to fit a 20G is only going to fit OTHER Mitsu turbos which leaves your upgrade path pretty fux0red. And all the Mitsu turbos use internal wastegates which are prone to boost creep at high pressure.

There's no benefit to using a Mistu turbo, just do a Garret. At least with a Garret T3 exhaust housing you can buy an off-the-shelf manifold to fit onto your BETA cylinder head. Can't do that with a Mitsu turbo...

Argarwal -

Personally I would go straoght for the T3/T4 hybrid, What I would do with this Turbo is just choose (with our kits, you have options of housings and wheels) a smaller turbine wheel to start with and if the need arrises (which it will!! Turbo's are ADDICTIVE!) you can simply upgrade the turbine wheel. It is still a scalable option and also a less expensive one!

Red - correct, also the Mitsubishi turbochargers are not as interchangable as the Garrett/Turbonetics units and sometimes you will need to either buy a complete turbocharger or make some tricky mods to build up a Hybrid one.

Vegabass15 - if you just want a slightly less powerful system, all you got to do is turn the boost down a little, remember our kits do not affect drivability of the vehicle, and the boost responce is not like a 50cc engine under 3000RPM, in fact with the monster I am using I achieve 0.2bar boost at 2500RPM already and full boost at 3400RPM, now your comp housing and wheel will be slightly smaller and be able to boost from lower too, what I personally like about the system is that up to 3500RPM with a light foot, you can drive very relaxed and easily with great fuel consumption! Got the best of both worlds!

When you need a little more acceeration, you press the gas pedal down a little further and the responce is immediate! I find that it is actually easier to drive than the Normally aspirated Tibby!

UFB/Red: Red, prepare yourself... stupid question here, I know you won't like it What's the "minimum" a T3/T4 can run with a conservatively sized turbine wheel? I ask before I know going straight to the T3/T4 would be cheaper in the long run, but I certainly can't afford all the internals needed to run 1bar at the same time.

If you tell me such a T3/T4 could run in it's efficiency range while @ 8-10psi (and later run higher, of course ), that would be nice. Any of you guys got a T3/T4 map? I could then answer my own stupid questions Thanks!

You can get a little tiny-ass T3 turbo for probably $400 that's only good UP to 1 bar on a 2.0L 7000K redline engine -- ie a 5-7psi daily driver.

T3's are not very big, T04's are the big boys, T3/04's are a hybrid using the T3 exhaust housing and a T04 compressor housing with a modified impellor and exducer wheels to match.

But yes, T3 turbos can be found in "sufficiently small sizes" to be useful on a stock engine.

[Agarwal]

Hmm... I know what they are
I was just asking if a T3/T4 hybrid could be used (ie, if it would be in it's efficiency range, given that you're using a conservative setup) as such a low boost (~9psi).


<hr width=60% noshade size=1 align=left>

 

[Red]

If you wanted to use a T3/T04 50 or 57 trim (or larger) then it would not be in it's efficiency range at only 9psi; they would probably be much happier around 12-15psi and even that may end up on the low side of the compressor map.

The T3/T04E I'm wanting to purchase is more of an 18psi daily / 28psi race type. I will probably have to run 110 unleaded to keep it at 28psi, but I'm pretty sure that a Haltech and 18psi on standard 91-93 octane pump gas and my 9.3:1 compression is certainly doable.

Actually, the engine volumetric efficiency I'm aiming for combined with the Haltech should make 400+ wheel horsepower at 28psi easily attainable, so long as I can keep the transmission in one piece <img src=/images/forums/snitz/tongue.gif width=15 height=15 border=0>

I'm still not 100% sure how I'm going to keep the transmission alive, even with a Quaife. There are still problems with the pressure plates on these trannies simply shelling themselves into sand after 300lbs of torque is applied in sudden doses (ie launching with sturdy axles on sticky tires)

I guess an APEXi AVC-R may be required after all, I was hoping not to spend that kind of money on a glorified boost controller.

Thanks a lot pal

i was looking here what do you think about the frankenstein level 1 or 2 turbo

Argarwal,

Here's the deal with T3/T4 hybrids in general and relating to our kits.

With the Hybrid turbochargers, you are able to configure the housings and wheels as you require at time of purchase. So depending on your requirements, the correct way of putting together a hybrid pump for yourself is to match it to your requirements, by using the comprsssor maps and CFM specifications.

If you want a turbo that will be a very drivable and not so "wild" setup - I would recommend you choose the following setup - it will give you veery decent boost reponce and alot more power and torque! This will be able to provide you with power up to 1.2bar boost no problem.

T3 .63 Turbine housing with a stage 2 wheel (smaller for better responce) and a water cooled center core, 360 degree thrust bearing, T04B AR60 comp housing, with the V comp wheel - if at a later stage you feel you want more power - you should then replace the V comp wheel with the Super V comp wheel which has a 76mm major instead of the 69mm major (bottom side of the comp wheel impeller blades) this will give you another 15 - 20 % increase in power. It is also very cost effective way to upgrade to more power and is simple and fast to accomplish.

All our Kits are configurable in this same way depending on your personal requirements.

Hope this helps,
