t1 tII tIII

[Alexwo1]

can someonse please tell me the difference between the 3 different turbo stages. Thanks

I wouldn't call them stages, they don't build off of each other. Here is a link that should help http://www.surpluselectron.com/aaron/22.htm with nice pics too.

They aren't really "turbo stages" (unless you meant to say stage 1, stage 2, stage 3 for SRT 4's only) they are designation of an engine type from Dodge. Here is a quick answer.

TI = SOHC 8v Turbo (no intercooler ?)
TII = SOHC 8v Turbo (intercooler optional ?, different intake and computer cal than TI ? )
TIII = DOHC 16v Turbo intercooled 224 hp (91-92 Spirit R/T 92-93 Daytona R/T ONLY)
TIV = VNT turbo intercooled apx 195 hp (any of the "VNT" designated cars)

Other members can and will give many more details.

T1 (TI) = no intercooler at all 146hp (2.2)
T2 (TII) = same as T1, with intercooler, more boost and different fuel/spark curves. 174hp (2.2)
T3 (TIII) = 16v DOHC engines (also intercooled) 225hp (2.2)
T4 (TIV) = 16v DOHC VNT (variable nozzle turbo, 16v) 225hp (2.2)

I think thats right...

TIV cars were not 16v, they were SOHC cars with the variable nozzle turbo and they had under 200 hp.

The Chrysler TC had the option of a 16v MASI turbo motor but I don't think it had a T number designation

Almost but the T4 is 8v and pre88 T1 had the log intake... maybe its pre 87... can't remember

Also check out www.thedodgegarage.com

and use the search button and search the turbo forum, I think glhsken did a break down of the various turbo stages, IE T3, T4 etc!

Everybody forgot the '88+ 2.5L T1. That was a non-intercooled, blow-through motor.

The VNT has 174 HP (apparently there was a big secret and it has only 164 HP) and 210 torque ... and was 2.2 (with balance shafts) and 8V SOHC too
