I need to be pointed in the right direction...[turbo suggestion]

[ECLEVO4G]

I have 98 gsx with rebuilt evo 3 block and 1g head ported. It's still a 2.0L and I am building the car up for track use and time attacks. I need to get a turbo that doesn't have lag and can support over 530 whp. Any suggestions will be helpful. I am really getting my car race ready too: roll cage, fmic, stand-alone, 1000cc inj, coilovers, carbon fiber, and eventually when I finish saving up money. Getting the total package on my transmission by shep trans.

What is your personal definition of lag?

Lag doesn't seam tostop all the big guns from getting great times. Do you mean circuit track or dragway.

530whp and minimal lag does not go hand in hand.

 

[ECLEVO4G]

I want to be able to spool around 3000 rpm or sooner if possible. I know there are numerous things that can increase the spool and decrease it too.

 

[JayRolla]

I agree any turbo you run that can make that power will have lag issues. The garrett GT ball bearing series are very good turbos and spool fast for how large they are. With a 2.0 and 500+whp you will have a little lag.

I also think if your going stand alone get some 1600cc injectors and be done with it.

 

[ECLEVO4G]

My car is for track use and time attacks! I know there will be a littel lag but I know alot of ppl have stroker motor and 2.3L engine. I know that I will be able to compete with those motor with my engine. I see a lot of the big guns uses a gt35r setup.

Not trying to sound like an A**hole but I think you need to do some more research before you start spending money on parts. By the way your making your posts it sounds like don't really know what your talking about.
evo 3 block on a 1g head, in a 2g? I think your looking for a nightmare
Race ready by putting a FMIC? Whats so race ready about that?
Carbon fiber? what hood, doors, trunks lids or what?
Big guns? thats just something amusing to say as is.
You should do ALOT of research before you put any money into that car, but hey its your money.

There currently is no turbo in existance that can support 530hp and be lag free. Also that evo3 short block will pop at 530hp, maybe not right away, but it will happen.

 

[DIS1KRAZY]

I am trying to do a simalar setup in my 97 gsx. But mine is fully built and i do the redline time attacks. The gt35r ball bearing turbo is a great turbo for the time attacks. You might want to look at a garrett gt 3076r or a gt3582r the 82 supports to 600hp.

 

[ECLEVO4G]

Ok well not to sound like an asshole back but I have done my research about this for about a year. Evo3 block is stronger than a 2g eclipse block and it wont crank walk like alot of the blocks. I really think you need to do more research before you comment about this. My engine is fully built which means internals are done everything is upgraded and the evo 3 block stock can hold up to 500 hp. I am just looking for a turbo that is effeceint, has a fast spool, and can produce power. The carbon fiber part is so that my car will be light as possible which means everything carbon fiber, but trust I did my research about this and seen cars up close. I have money like that so it wouldn't matter but I am smart cause I won't by any crappy product

 

[xdxoxuxgx]

I would suggest looking into ball bearing turbos, they're gonna be the ones that will give you minimal lag but still be able to produce decent HP depending on how big of a turbo you go and what kind of boost you're looking to run.

 

[dsm-onster]

They yield 15% quicker spool at best. A typical journal bearing 530 whp turbo (60-1) will spool well by 4200 rpms. 15% quicker spool would be around 3600rpms at best. Transient response is were the most benefit can be seen look at the top of the curve to peak compressor speed of the graph in the link. The ball bearing does better between shifts because it doesn't want to drop the rpms as quick.

I want to be able to spool around 3000 rpm or sooner if possible. I know there are numerous things that can increase the spool and decrease it too.

There is no turbo capable of that horsepower AND capable of that spool speed on its on. So you will not ever reach that goal with current mods.

To spool that early:
1. nitrous,
2. Or take the engine apart and run a stroker,
3. Or twincharge (meaning feed a big turbo into a supecharger that is feeding your 2.0L engine
4. Spend tens of thousands of dollars on a variable gas turbine for what ever turbocharger you would like. . . You said you have money.

All your research has left you asking what turbo can spool before 3200 rpms and flow enough for 530whp? If you have to ask, then there is no turbo that can do that. If you don't like that answer or don't believe that answer, then you're research is not complete.

And coming to _DeS_ defense, you did not state your block was build nor did you fill out your profile. 'Rebuilt' commonly means re-using. And re-using evo internals will be questionable at best in a 500+ whp goal.

 

[ECLEVO4G]

Thanks for the info and for me to be going into timeattacks and racing my research will never be complete. I have a few ideas on ways to get any turbo to spool faster, all I need to do is do trial an error with my ideas.

thanks for the info

Well, the GT 3582R with a 0.70A/R T4 flange is an excellent first choice for mid to upper 20's boost levels for racing on at least 110octane leaded gas safely with a set of 1000cc injectors. I would REALLY reccomend doing a twin fuel pump design with a fuel cell and a surge tank. Seeing the lateral G's that road racing entails makes a much more complicated fuel setup than just dropping in a 255HP in-tank and calling it a day safely.

If you are intending on running C16 and 30+psi during all the track stuff, then the GT3076R with a 0.82A/R T3 housing would be a good choice -- I would personally reccomend the lower boost application using the GT 3582R or HTA version being sold by Forced Performance because of the continuous abuse you will be seeing by running high boost for extended periods of time.

Both turbos mentioned above should be getting its oil feed from the oil filter housing if being used with a standard oil pump setup. Also with using the standard oil pump setup, you should probably go with a larger sized oil cooler (i.e. Setrab 9"x11" with -8AN lines).

Both turbos can make 500+whp, but so can much cheaper turbos like a SCM6031SP, SCM6152SP, or a T3 or T4 flanged SC61 using a turbine housing ranging from 0.70-0.86 A/R.

Either way, I hope you are investing in a Ralliart dry sump oiling setup, or at least a higher capacity pan with baffles and trap doors w/ an oil cooler if you are really serious about making a RACE car.

As for road racing and/or drifting, please tell me how much of the time you are going to be below 3K RPMS anyways....RARELY. Spoolup really isn't the problem you should be looking at. Reliability is the key component you should be researching.

As for the comment of "I have a few ideas on ways to get any turbo to spool faster, all I need to do is do trial an error with my ideas."... many of these things have been done before -- it isn't ground-breaking, so you should do more research before wasting your money. We have "been there and done that", and some people here can give invaluable advice which will save you time, money and headaches.

+1, and there's no turbo out there capable of supporting 400 HP let alone 530 that's going to be fully spooled by 3000 RPM. Even using nitrous, you cna't bring it on till after 2500 RPM if you wnat your motor to last and then there's going to be a split esecond of lag still yet that's going to put you into 3500-4k area by full spool.

No worries man, you sound like newbie, not an asshole. Evo3 blocks are not stronger, thats a common mis-conception among jdm enthusiasts here in the US. At 500whp a stock evo3 block with stock internals will eventually fail, no doubt about that. After being a member of a couple Austrailian and UK Lancer boards I can tell you right now that the evo3 is just as prone to crankwalk as your average 2g. Also why didn't you mention the fact that your engine was "built" in your first post? We're just suppose to assume you know what your doing? The fact remains if you are here asking questions like this, you have not done enough research.

For what you are looking to do I would suggest an fp3052, with the proper mods it will support over 500hp and will provide the quickest spool you are going to find at that power level.

 

[ECLEVO4G]

I will never have done enough research cause there will always be more information out there for me to obtain. Trust no newbie here but to this website yes but to cars and racing nah! I appreciate everyone's input and take what was said into consideration on what I am trying to accomplish. She will be ready soon

 

[Mikael SS]

ported head and big cams? that is often an overlooked part that can help spool.

a stroker would make a noticeable difference if you want to rebuild the motor

 

[Hideki]

EVO 3 is a 7-bolt and just as prone to crankwalk as a 2G...

 

[dsm-onster]

Long duration usually makes for slightly later spool; but once spoolup begins a faster rise to peak boost. At least that is what occured with my setup. It's interesting that, based on speed of sound differences in a boosted setting (around 30 psi), the effective close duration of 272s match the 3rd order harmonic of a 1g head/intake perfectly at 4600 rpms and the 2nd (best you can reasonably get!) at 7000 rpms. A 1g head intake is ideal for his goal IMHO. He can drop as low as 4600 rpms and still be peaking into a harmonic many manifold designers are building for. An yes a stroker is ideal and compliments here.

And kudos to Twicks for hitting the nail on the head. How long are you going to be under 3K? As you get better, less and less. You probably are capable of staying above that now .
