thought we should have a vote so i've made it a pole :cheesy:


i haven't driven a aero in ernist so i cant coment on how good they are, so i'm going to vote for the T25 as the T3 is slow to spool up but does give good top end boost

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

1984-=1988 2.0l 9000 had T3


1989-1990 2.0l 9000 had TE05


1991- 2.3l 9000 (exept aero) had T25

Hej !

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

Here's another one for the TD04.

I'm driving a 9000 2.0LPT auto with the T25. Although i am very happy with it, my vote goes to the TD04.

I'v driven a 9-5 Aero once and i really liked it. No lag and it kept pulling like hell at higher rpm. Contrary to the 2.0LPT, which works fine (no lag) until 3.000 rpm, above nothing much happens.

Regards,

JP

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.

Anyone ever put a non-standard turbo on a 9000? Or seen one put on? What other turbos work well with the 2.3 or 2.0?
A friend of mine is running a Cosworth style T3 exhaust housing with T4 compressor and modified JT downpipe on his '87 9000. The car really needs setting up properly now.

T3 from me.

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)

Sorry, I drive a 900 :lol:
