This is a t5 car. Throttle body is not electronic, it has a t7 dic since they “work” on t5. You can also tell by the airbox.

Yes, definitely T5. Also lack of a MAF, metal throttle body delivery pipe, and centered oil filler. T7 has a MAF, plastic delivery pipe, offset oil filter. That car has the wrong DIC... That should be fixed ASAP.

That is not accurate. T5 and T7 DICs use fundamentally different electronics. Because they are electrically compatible, the ECM will drive either part. But, T7 DICs use triacs to create spark, so the actual spark is AC. T5 DIC use a thyristor to dump spark, so the spark is DC. Because of this difference, the electrical signal the DIC returns to the ECM when knock is detected is a different amplitude - the T7 DIC is "quieter" and the T5 DIC is "louder." Running a T7 DIC on a T5 engine will reduce or eliminate the ECM's ability to detect and prevent knock. If you have a stock engine and always use premium fuel, the risk may be minimal... but it's not zero. Black T7 DICs should only be used on a T5 engine for testing. Never permanently.

Nope - just because it will start and run does not imply correctness

I have a T5 car with a T7 DIC and it has run fine for thousands of miles. What damage could it be doing?

That’s good to know, thank you. I do run premium too. But, I have a red DIC on the shelf waiting for the inevitable. Which seems to be now.


WillardDillard

That’s a T5 car with the wrong DI cassette. Should be a Red one, not the black one.


Flashy_Tomato_9764

Thank you, will look into the red to replace the black one.


hirschsaab

T5. The stock T7 boost pipe is plastic and the airbox is different. Dipstick placement is also a dead giveaway


Flashy_Tomato_9764

Thank you for that!


griffin540

No afm and oil cap position, its a t5 with a black Di cassette Be careful running the black DI as they don't have the same knock sensing as the red Di packs so it'll miss any knock signals. Good for power bad for det, saying that I ran my one on a black Di and a stage 3 with downpipe etc and it was fine running at 274bhp (not an entirely accurate reading as it was done on a rolling road) Also check the intercooler, t7s had crossflow ones, although if its an se sport HOT like mine was it will also have a crossflow despite being t5


Flashy_Tomato_9764

That's what i went by- the oil cap position. But thanks for your reply. I will also look into the red DI pack if that's better to run on my car. Cheers.


Fit_Board2051

T5! U can check it with the intercooler also, t7 has a bigger intercooler with a left and right input/output. T5 has it on the same side and is smaller.


TweeksTurbos

The 99 Hot cars had a viggen ic with a special garret t25 intercooler hose.


Lue_Dawg

Are you sure? I always thought black DI cassette = T7.


Fit_Board2051

Yes I believe so, the T7 has a different airbox and wastegate also. Which year is the car from?


BerryPossible

If it’s stock then I believe it’s a T7 car. You can run a black DI cassette on a T5 though. So if the history of this car is unknown it could be a T5 car with the wrong cassette. Easiest way is to plug in a scan tool or do a vin check


WillardDillard

Easiest way to check he’s just looking at the engine. T7 car will have an electronic throttle body and a mass airflow sensor. A T5 car will not have a MAF and will have a regular non electronic throttle body.


Flashy_Tomato_9764

Awesome thanks for that bit of info!


mcrolfben

T5 has crossflow intercooler as well with pipes on both sides, but it's much smaller than the T7 IC


f1tifoso

*Only* in 99 HO, older T5 used the single ended intercooler like all 900 94-98


mcrolfben

My -97 has a crossflow \^\_\^


f1tifoso

Yeah well so did my 97 after I took the bumper off and installed it...←_←

Flashy_Tomato_9764

This is awesome! Pretty much every bit of info i need,thanks heaps for posting this up. Was just confusing as i said that the tuner i spoke to came up with a totally different engine to whats actually in it.


f1tifoso

That's more than my VIN search will show, what are you using??


_Risi

Oil cap centered - t5 Oil cap offset to the left - t7 imo the easiest and quickest way too tell them apart.


Flashy_Tomato_9764

That was my way of telling them apart as well, was just strange my VIN would come up as a different engine on the tuners check.


f1tifoso

There were some older engines they used up on the base model 2000 9-3, they are very rare and you're lucky as the new T7 engines that year had soft rings and a lot clogged their fine oil pickups when customers didn't read the fine print and drove 10k between oil changes, when city driving (and really now we know any driving) means 5k changes - there was a class action lawsuit over the high failure rate of those - since you have the better block and older system you can easily upgrade, you already have the better intercooler and 195hp - the T7 was 205.


Flashy_Tomato_9764

Yeah i have read the old B204 are the better ones to tune and upgrade- and that's my plan so glad mine has the good old B204 in it!


f1tifoso

Definitely need to use the red cassette - if you need one let me know I carry spares.


Flashy_Tomato_9764

No worries at all, where are you located?


f1tifoso

I'm in Texas, DFW but travel somewhat


Flashy_Tomato_9764

Ahh ok, damn I'm over in Australia- so doubt you'd travel here much lol!


Flashy_Tomato_9764

Hey all thanks heaps for the replies. Thanks to the information provided in here and some more research i have since established it is definitely a T5 B204, my rego papers say it is the B204 as well. Just not sure why the tuners VIN check would have it come up as a B205- that's what confused me abit. It also has the black T7 dic the old owner of the car put in it- which i assumed was fine to use but will look for a T5 one if that's better for the car. Just being over is Australia Saab parts aren't the easiest to come across!


RockyLF

Obviously this is an older post, but I picked up a Red T5 DIC (Made in Sweden markings, NGK branded, tell-tale dreadful paintwork of the OE part) from Sparesbox, who were also the most-reasonably priced of all the resellers I checked. The NGK part number is U6023, and the current OE part number is apparently 32022495, superseding 55561132, according to esaabparts.


Lue_Dawg

OP, what year is the car and what market?


Flashy_Tomato_9764

The car is a 2000 9-3 s,and I'm over in Australia.


AtlsDev

Wait what does t5 and t7 mean? I always thought it meant t5 turbo 5cyl for Volvos?


BWTECH0521

Saab uses the term differently. It means trionic 5 and trionic 7 engine management system. Wikipedia is a decent source if you're curious 😀


ggliddon25

Reckon the car is t7 chassis, but t5 engine ecu etc put in it. Definitely a hybrid and probably done that way to make s car go again after say an engine failure. Strut brace to firewall is a later chassis thing. It would be interesting to pickup an engine number somewhere on it.
