2000 volvo s40. Usa so it's a t3. Not t4

[Boc576]

Hey U.K. Volvo guys. I have a 2000 s40 hear in the USA. I've put on an intake and modded the exhaust slightly. What do you guys recommend to give her a little more pop? Thanks! I do have a lightened crank pulley but it has not been installed. I'm worried it will kill my motor.

Is it a 1.9 or 2.0?

The 1.9 is the stronger engine and apparently the standard ecu copes quite well to a manual boost controller.
You must fit a boost guage though and not get carried away.

Don't understand why the crank pulley would kill your engine?

Welcome along by the way :)

Some think the lack of a harmonic damper can damage the crank, I could see it happening with some VW cranks but a White Block crank's a little bit stronger lol.

by the way. i really wish there were aftermarket cams or a cam swap from another model available. i used to have an old chevy 350 small block and throwing a cam in that motor made a serious difference

[Doingitsideways]

It is possible to swap in cams from a N/A engine.

There's been much debate about it over the years, but I have them in my T5 and I like them.
They take a bit of setting up, but can be done.

Google is your friend in this case, I seem to remember a change from hydraulic lifters to solid on the T4 and cams from the two aren't interchangeable

[Tim Williams]

You can get cams for the T4 or get them reground. I've fitted reground ones before, with a suitable sized turbo the cams on their own will give an extra 2000+RPM at the top end. A GT30 and 1mm higher lift cams and they can pull cleanly to over 10k. With a 19T or K24 you're looking at about 8.5k.

so the T4 from europe and the T3 or T2 or whatever it is in the US has different cams?

[Tim Williams]

In the U.K. The only turbo ones we got were 2.0T LPT and T4. The 2.0 T is 83mm bore and the early T4 was 81mm, the later T4 83mm bore. I think in the USA your T4 with an 83mm bore was the same as our 2.0T.

I was referring to after market cams not using a different Volvo cam as an upgrade.

I have looked around but i havent found any company that makes an aftermarket cam for a 2000 s40. know of any?
