I bought a 99 9-5 2.3 lpt with a blown engine. I was thinking about putting a new turbo in it as well, but am now thinking that the LPT might be better for me. I do not want to do a bunch of expensive mods. I will only do a stage 1 ecu. 175HP is just not enough but 200+ is just fine for me.

My question is, the Garret turbo is supposed to be lighter and spool up faster. I Like this idea (my 95 NG900 Converto has plenty of power, but only after 2500 rpms's and only 185 HP)

So, if I can get Aero power, just by a stage 1 ecu remap and keep the short spool up time without further mods, why would I ever want an Abbot turbo?

I dont mean to be condecending, I am still considereing the bigger turbo, I just would like to hear from people who know more about it than me.

I dont understand your reference to Abbott?

The bigger turbo is the mitsubishi TD04 Aero unit. Abbott are a tuner who specialise in enhanced parts (including turbos), so I dont think thats what you mean, is it?

If stage one is all you need then the garret is fine, less reliable but fine ;)

Do'h!

I have ECU upgrades on the brain...

Yeah, I meant mitsu turbo, and thanks for the advice, I think i'll probably stick with the garrett.

You will never get aero power with just a stage 1...... Maybe you are getting confused, Abbott racing do supply a hybrid Garrett turbo. It is about 25-30bhp less powerful than the mitsi tdo4 aero turbo. However the hybrid spins very fast and very quickly so you dont get the lag associated with the td04. So you pays your money you takes your choice. It depends what you want from your car. :)

How quick do you need it to spool up? I have full boost by 2500 rpms, and I'm sure it'd be a lot sooner with a downpipe. Everyone at the drag strip was calling my turbo small. :cry:

Raven I cant comment on the aero engine as I dont drive one. However all the cars I have driven with the tdo4 turbo conversion are not at full torque at 2500k :confused: . The Mitsi Unit is a great turbo and the power it produces is truely awsome. The first time I drove with one was the Abbott development car, the day they first fitted one to it.. It was like a nuclear bomb going of behind me, Boom.... 0 to speed of light in about 3 seconds :) . The hybrid doesnt kick quite so hard as the mitsi, as it has started to spin at very low revs, the power applied is much more even and not as ferocious..

2.3 with Stage 1 gives out 234 bhp

Early Aero's had 230 bhp ;)

I realise bhp values will be similar but I cant believe that the gt17 will ever give the punch of a tdo4.. Even if it has gone hot.:)

Sorry still dont agree :confused:

  • 1999 2.3 SE - stock 170 bhp 280 Nm torque
  • 1999 2.3 Aero - stock 230 bhp 350 Nm torque
  • 1999 2.3 SE BSR Stage 1 234 bhp 378 Nm torque
The SE only loses on supsension and braking, even the seats are the same on the early ones ;)

I guess then you are right, ;oops: But I still believe that tdo4 will give out a different power curve than the gt17. :)

Most certainly, I think the ECU is restraining the TD04 a lot, cause all the non stock B235R's I've seen are making full torque at 3000 and not 2500. Once I have some money to afford uprating the power it'll be a monster.

as a comparison between the garrett T25 and the mitsi TD04, a friend of mine (yes i do have some :lol: ) has a 9000 aero and it had the T25 turbo fitted at some point before he bought the car so decided to fit the right turbo, the TD04, now wishes he hadnt as the spool up is better on the T25 :roll:

With ECU you can get almost as much puch to the low revs as you wish with the 15T, it all depends on how the other parts are up for the job.
Here is old plot from my viggen when it still had the TD04-15T
[email protected] should be enough for the most of us :cheesy:

The main problem though with the 15T is it lack to maintain the power level in high revs, resulting to "poor" perfromance when you're runnin up the gears when rpm remain above 4000rpm after each shift. I personally felt that the pull pretty much sucs above 5000rpm or so.
Here is one video from which you can get the idea of the spool-up with 15T

:eek: Sweet jebus on a bogo stick! That's a lota torque. How much boost is that making at 300 rpms?

Depends on wether and other stuff, but from 1.1-1.5bar, normally around 1.3bar. Keep in mind that I have a big IC which will keep pressure levels lower due to lower temps.

I'm actually planning on getting a FMIC and downpipe before I even think of chipping this car. I was curious cause I want to know how much boost the FMIC will have to hold. What kind of software are you running and did you have to get it tuned?

I dont have that set-up any more. Here is a link to the up to date spec.

I had to have my SW retuned after IC install due to leaning out.

Performance did not improve much after IC upgrade, but I did help with back to back pulls. Before the job after one 100-200km/h acceleration the IC was heat soaked and would raise temps up to 100deg C. With the new IC this was dropped to 50-60 in same ambient temp and it helps to keep up the performance since timing is not altered due to knock issues and SW setting.
Many after market ECU's will start to alter timing and airmass once 60deg C is reached.
