Maybe you need a good tune on your mivec map and fuelling...

 

Actually why don't you find it? I'd be interested to see the results as well. And I'm sure you're better at searching than me

 

WTF? Die in a fire nub.

 

^ That cracks me up. My luck i'd do a large, oopsy-strategic shot of out-of-control with No2.

Now i dont understand exactly what some of this is... like CFM/efficieny ranges? that's how efficient the turbo is at... well being a turbo? a gt28 turbo is smaller then a gt30 right?

How much could these set ups potentialy cost?

Wingless- so that Garrett gt28 is one you'd put money on if had to get one.... Your right to the fact that i'm fine with the stock power of my evo, alittle more here and there would be fine but really i'd just want less lag.

 

Port your stock exhaust Manifold as well, and it probably wouldn't hurt to get it ceramic coated or wrap it and wrap up a new downpipe, hotter gases = faster movement and faster spool.

 

"It's not lag, it's foreplay."

 

Removing any post-turbo exhaust restrictions should reduce turbo spoolup time, as others have mentioned. Also, an aftermarket O2 housing, 3" downpipe, replacement of catalytic convertor with a test pipe, should all improve spoolup.

Also as mentioned above, having your ECU's ignition timing and fuel tables modified can noticeably improve spoolup for you. Swapping your stock LICP for an improved lower intercooler pipe is also a goood alternative. At least on non-MIVEC Evos, advancing the cam timing via adjustable cam gears is a proven way to improve spoolup.

Since your IX turbo comes fitted with the 10.5 turbine housing you can always step down to either a 9.8 housing or even a 9.0 turbine housing. This is guaranteed to drop spoolup time and only costs a couple hundred bucks.

I just ordered a 9.0 housing for my EvoGreen from Forced Performance with an eye toward improving spoolup time. So, you could fit a 9.0 housing onto your IX turbo. It should be a straight bolt-on replacement and only costs a couple hundred bucks. Whereas a ball bearing conversion is way more expensive.

EDIT: Ditto a 3071 is not going to spool fast. A GT28(?) is not gonna get much approval on this forum. A properly setup bolton turbo should blow it away and do it cheaper. No one uses that GT-28 thing on here!

If you want real fast spool for cheap while retaining your IX turbo, then just send it to Forced Performance and have them install a titanium turbine wheel and a 9.0 housing and get rid of your catalytic convertor.

 

shouldn't you pretty much always be in boost while road racing?

 

This is the best solution for your Quest.
Still a Powerfull Evo IX Tutbo, and less Lag.

You can sell your Turbo and help pay for this new one.

There is no other choice if you want to keep a Turbo that makes power and spools fast.

Good luck.

to be honest, if you want to increase spool i would leave the turbo alone. I think you will end up spending a lot of money on something that will either worsen the lag (any larger turbo basically) or will cut down on your hp numbers. Follow the tips that others gave you, free flowing exhaust, ported exhaust manifold, maybe a few other boltons, and also get in contact with a good tuner, tell him your goals, and see what kind of map they can set up for you. A tune is arguably the most important part.

 

^^^^^^^^^^^^^^Yeah that oughta do it for you^^^^^^^^^^^^. And if that still isn't quick enough then put a smaller turbine housing on that Mag/Tial turbo.

 

it took two pages before someone pointed out the TME... bout time!

 

eh, i'm not quite sold on the tme idea yet, seems like a good deal of money for not too much of a gain. Here is a thread with a bit more info on the subject

You should buy a Tommy Makinen Edition turbo with the Magnesium compressor wheel.

There was a car at a local tuning shop with one and it started spooling @ 23 or 2400 I believe. Because it has a lighter wheel there's less rotational mass which ='s a quicker acceleration of the turbine wheel. It also has a titanium shaft I believe.

I would also stay away from any camshaft bigger than 272.

Im gonna call bs. 23 lbs at 2400 rpms? Was it a K03 turbo?
