TRi TRi122?

B-Hive · Post by **B-Hive** » Tue Aug 23, 2011 12:43 pm

Not sure if it a tech question but how does one identify the difference between an 88 TRi and an 88 122 TRi.?

Excepting of course for the badge on the hatch which may or may not be be there appropriately, are there any other key indicators that identify what is a 122?.. maybe the 122 head has flat spark plug washer seals??

not sure.!!!

looking at a mint "122" far away but doesnt have the 122 badge on the hatch FWIW..

please be quick ..want to place a "sight un-seen" offer if its a 122

Could it be that one has a catalyst and one doesnt?

My catalsyt equipped 19TZI (which is basically a faclifted TRi) according to the tech spec has 122bhp where as the GTi is 125, the engine spec is much the same but its the addition of the cat converter that recuces the engine power slightly.

Additionally they could be the same and one has a badge and one doesnt.

Its just the standard TRi has 105Hp and the 122 well has 122..my ("standard") Tri has a flat/washer plug head and has astounding performance. The head is not the normal fit and going by the performance, I think it might be a high performance/bigger valve head that separates it from the standard tune TRi.

The TRi I am looking at has no badges, and the advertising web site might default to showing the car as a 122...

Vendor is checking his info but it'd be good to know what to look for in advance should i take the 800km (500 miles) trip to see the car

All post 87 cars in Australia have a CAT....the 122 usually have the badge but as said that is no indication one way or the other...car is being sold as a 122 so needing to know the "look fors"...thanks

If the heads are different it could be one is a "single point" fuel injection and one a "muti point" (as per the GTi)? which would give a difference in BHP.

I changed my mind half way through!

no they are both the 1.9 but some of the later models bumped the 1.9 from 105 to 122... assuming Citroen used the 8v GT head to lift the power (and torque)..similar to the 8v GTi...(we didnt actually get the GTi in this country)

Could be that as you say it had the GTi head fitted then which gave it more ooomph!

Thinking my TRi may have had a 122/GT head fitted... but my question remains ..how to differentiate a standard TRi from a 122/GTI model...is it the head..the computer ...the extractors...

I dont wish to drive 800km and back only to decide its not the "better" /desirable model

Get some photos of the engine bay.

I thought the 105 was a carburretor 1.9 whereas the more potent one was multipoint injection ala Gti 8valve?

"over there" Matt the later ones were all fuel injected and normally ctalyst equipped sue to stricter emission laws I think.

I thought the tzi had a different inlet manifold to the gti, wasn't it smaller and only had one butterfly compaired to the gti's twin butterfly lay out?

Not sure to be honest, could have a look. Surelys something like that would reduce power by more than 3bhp?

It seems like there are so many variations in engine spec...

guess all i can say that, all things considered, the GT and TRi are such rewarding cars to drive... irrespective of what there outputs are... think I have sorted the issue with the GT by rewiring the carb float chamber vent solenoid...long run today...big fun factor

Decided against going for the "122" ...nothing against it but I simply dont need it.....(still want it though)... need to take my pill!!
