ok, not really comparing turbo's, but an MY00 9-5 Aero, TD04, gets peak boost around 2000 rpm, goes well, no noticble lag. '87 9000 Turbo, T3 turbo, peak boost 2500 rpm. goes well, little bit of lag. I liked the 9-5 alot!, :cheesy:
I can't claim a lot of expertise with the other two, but I'll throw in my vote for the T3. I'm happy with it. Low end is kinda lazy, but I really don't put the hammer down unless I'm already going 50mph.
Here's one for the TD04. You didn't specify which TD04, either. I've never experienced a TD04-18T, 19T, or 16T for that matter. However, I've had a few years experience with the TD04HL-15T and larger injectors. I never really had any issues with boost lag, and my peak boost pressures, from 3.5-4.5k rpms, were at 1.65 bar. It only tapered down to about 1.2 bar at the red-line. The software was MapTun's stage 4, but I never got the chance to have it dynoed.
Anyway, the TD04 was/is a very nice little turbo and has the potential for much more than 300 hp with the larger turbine (7 cm^2) and compressors (16, 18, & 19T). However, if money weren't an issue, I'd shell-out the $$'s for a Garrrett GT2871R.
i've added another charger to the list that i'd forgotten about, the TE05 it was used on the 2.0 between the T3 and the T25 for about 2 years i think in 89 & 90 it was smaller then the T3 but used the same manifold flange unlike the T25 that uses a smaller flange
IF we're talking about stock TuRbochargers, I see little or no room for an old antique thing as the Garrett TB03.
Garrett TB03 vs. MHI TE05-12B:
The TE05 will reach boost earlier and quicker, however at the high rpm range (above stock boost) it becomes "lazy".
Remeber the old tuning kit for the 9k 2.0 where the vehicle equipped with TE05 had 204 bhp and the TB03 slightly less. This with exactly the same boost pressure.
TE05 is a nice TuRbo, but not for "race".
The TB03 is never nice...
Garrett TB25xx vs. MHI TD04HL-15T #5:
No questions here, I prefer the TD04, better low-mid and high rpm range. Better quality.
MHI TD04HL-15T #5 vs. MHI TD04HL-15T #6:
The #5 turbine will make the low and mig rpm range stong, where the bigger #6 turbine reacts a little bit slower at low rpm range. The #6 will make the engine a much stonger at the high rpm range.
Rule: (just remember that rules can be broken....)
2.0 up to 250-260 bhp = #5
2.3 above 240-250 bhp = #6
2.3 up to 230-250 bhp = #5
2.3 above 220-250 bhp = #6
I would have to go with the T3, just because its whats on my car. Not to mention its just a good all around turbo. Its fairly large, but not big enought to cause lag up to like 4K. Yet large enough to pull like mad high end.
Just a good all around turbo I think. T25 spools quick, sure, but it blows high end. My friend's couldn't even keep 10PSI up to his 7K redline.
I always thought the T3 on the 2.0ltr was great. Very reasonable spool, excellent mid-range and fair top-end. Though now I have a GT28RS71R so nothing compares (except an identical car with a tuned EFI and ignition setup)

I'm going to be requiring a set of injectors and somone to map the ECU...
I have a 97 9000 aero manual. I have a boost control valve to adjust the turbo boost. When you open it it gives you a lot more boost when you close it a little bit it gives you less boost. Now it doesn't matter whether its closed or opened it gives the same boost. I removed the hose from the...
I was thinking of converting my manual 9000 to automatic and are wondering how hard it would be. Yes I know the reputation of the automatic, but I don't care. My car isn't stock anymore, because previous engine died.

Hello, I’m buying my first Saab. It has the b234r 2.3 with 260k miles. I’m already putting a new radiator and probably hoses in it but I’m wondering where to start on preformance. Also anything you’d recommend replacing since it is a 260k Mile car. Just wanting to make it a pretty fast and...
