I have a 2003 Yamaha R1 engine that I will be installing freeEMS on in the near future. Right now it makes 165HP. I wish to raise its output with a turbo, to about 220HP. I am told 220 ish is about the max you can make with stock parts.

I need advice on what turbo will work well for this application. This engine will eventually go into a desert/sand rail.

Here are the specifics on the engine.

liquid cooled
.98L inline 4 cylinder 20-valve
11,700 RPM redline


Thanks,
Sean

Does anyone know the author of that article?

Not personally but I recognized it.

What about this. TD04HL-16T-6
Would make for a nice self contained setup with plenty of room to grow.

He's the author of MT, I was trying to be funny.

As always you need to size your compressor to flow the air you need and your turbine to spool when you want and choke acceptably.

The trouble with a bike (but not a sand rail) is that if it comes on boost suddenly it could throw you off.

TD04 is probably a good choice, certainly they are cheap enough to play around with :-)

I am budget minded!
I'll see if I cant find one at a junk yard in the next few weeks.

I've got an IHI rhb5 from a 2.2L Mazda...it's probably smaller than what you are looking for though. I also have one that needs rebuilding I would part with for the cost of shipping ~$20 or so if you are interested.

It's probably sized about right. I'll do a little more research on it.

Thanks for the offer,
sean
