95 T5R engine

Where are you??

T5 engines don't grow on trees, best bet would be to find a local scrapyard that deals in newer European cars, I don't think the R motor itself is any different than the normal T5, that'll be a rather expensive motor though, next time keep oil in it.

The R motor is different from the T5. The R motor are at 250 bhp with manual trans. 245 bhp with automatic trans. The T5 motor are at 225? bhp.

I still don't think the *motor* is any different, the ECU certainly is, as well as the turbo in the R may be a bit larger, but the extra power is created by higher boost and a different injection curve.

It is different, why would Volvo give it a different name, B5234T5, if it was only the Ecu? I know at least the main end bearings are stronger, i think the injectors are bigger too. Of course you could get a B5234T and use that, it will for sure hold up for that small power increase.

Dont know what have seized, but i prefer to repair the old engine, then you know what you have, buying a used is always a risk.

Isn't the B5234T5 used in all the T5's, not just the R? If not then I stand corrected.

The 225 hp T5 models have B5234T The 240 hp T5R or R with aut. trans. have B5234T5 The 250 hp R with man. trans. have B5234T4

normal aspired turbo and T5R

All T5R engines are the same regardless of what the tranny is, the only difference is the manual put out 5 more horsepower do to the gear ratio Manual 250hp Auto 245hp

The difference in a T5R engine and a regular turbo is the oil lines and the way the water is routed through the engine, and they are only slightly different. So do not try and put a T5R turbo on a regular turbo engine as it will blow the engine apart. The extra HP developed by the T5R comes from bigger injectors and the waste gate on a T5R are electronically controlled, while normal tubos are vacuumed controlled. This makes the T5R turbo more efficent.

Have to correct you on some points.

There are more engines than what you say, perhaps the number is limited where you live, but worldwide the number is larger, I just counted 9 different engines in 1995.

All 2.3 litre T5R engines are named B5234T5 and are off course the same. In some countries there was a cheaper 2.0 litre version with 225 bhp, B5204T3. The ECU program in the manual and auto version differs slightly. The effect in both version is 240 bhp at 5600 rev, but the torque is limited to 300 Nm in the auto compared to 330 Nm in the maual version.

The B5234T and B5234T5 engines have the same injectors, same oillines etc. They both have electronically controlled wastegate. The B5234T5 engine is basically a B5234T engine with up to 30 seconds overboost raising the effect from 225 hp to 240 hp.
