iX stroker turbo Questions

[nando]

a stroker makes a pretty good daily - but I don't know if a 3.2 would get you to 200whp or not. it's harder with awd because there is more of a drivetrain loss. A stroker that would get you to that much power would require a lot of work to the head - an agressive cam, well tuned intake and exhaust, etc.

I think you're better off going with a 2.8 turbo - lower boost should be plenty reliable and a lot more economical to reach your power goals. Plus you can always turn up the boost for fun times :)

if you want a setup to copy - I'd do a motor like blacktrail69's. I think he was making something like 400 at the crank, with room to spare

if you want reliability from a turbo:

a) overbuild the engine - headstuds, welded coolant channels, forged pistons, etc. the only things different on our engines are the block, oil pump and intermediate shaft. so you can copy what other turbo people are doing.
b) use an intercooler. you may be able to get away without one, but even an inexpensive one is better than nothing. the outside temp might be low, but under pressure air temps rise significantly.
c) tuning - megasquirt, vems, whatever. it's probably worth getting some dyno time if you're going to turbo the car. AFR is pretty easy to dial in (especially at WOT) but timing is impossible to street tune, and the rest of the map takes a lot of time/effort.

if you had ~200whp, you'd be able to do what you want - i'm not close to that, and 5th gear feels like 4th on the freeway. The only time I downshift is for 3rd gear passing from ~45-85mph, which is a blast :)

To get ~200whp would I have to go the route of the 3.2 motor like youve mentioned before? If so would that be a good reliable daily/as well as easy stock like maint.? Probably wouldnt be able to use stock ECU huh?

I feel that once I have that motor out and plenty of time to do it right, I might as well go big, but not at the sake of reliability. Turbo seems like a can of worms too with problems to deal with down the road. Am i asking for too much from an M20?

My buddy and I are turboing his ix. Its going to be sick. You should turbo yours as well. The boost is what will easily make up for the loss of power due to elevation. :)

As far as reliability I have had my car turbo'd for over 10,000 miles and it gets 20mpg around town and 24mpg highway. I am more than satisfied with it, and I havent even installed my standalone ecm yet:)

dont have any advice but a turbo IX would be awesome!!

I am currently doing a lot of research on the stroker I want to build for my iX. I plan on building something similar to nando's 2.8, so nando feel free to chime in here. I will be back in Colorado at about 8k ft. so basically I want my stroker to be able to perform like it would at sea level, be able to push/pass trucks and cars up hill on the highway over high mountain passes without a lot of down shifting. I also want reliability to be a must. So I am wondering if a mild boost would be a good idea for what I want. I want to do it right, no cheap set ups. Is an intercooler necessary, considering temps are never really that high up there? Would the stroker alone be enough? The key here is reliablity. Any ideas on this? Thanks.
