You've got to pay to play...

My estimated cost was around $4500-$5000, probably more and I did 85% of the work. That's including the 1st Bp-t engine I spent mega bucks on. I'm on my second now.

I BET you're on your second now, with 250 hp and 257 ft/lbs to the wheels

What happened to the last one... did it blow? That'd suck. You really should look into one of those Flyin Miata strokers at this point.... yeah they're really expensive, but damn it'd be awesome.

I never dynoed the 1st engine, just bent 3 rods soon after it was running. How did it happen? A 25 lb boost spike at 3000rpm happened. The wastegate vaccum line was plumbed in wrong so it never controlled boost right. I fixed the problem immediately afterwards, but the damage was done. Bent rods broke off an oil squirter inside the block which spun all the rod bearings and started to damage the crank and main bearings.

The power it's making now is tunned and the wastegate still has trouble controlling boost. The wastegate is set at 11 lbs but it climes up to 15 due to almost no backpressure and to an extent, the wastegate design and downpipe.

I am doing the Bp swap then doing a turbo convertion. SOo far I have probably spent around $1800 and need around $800 more to finsh. That $800 includes, $400=Exhaust, $150=Flywheel resurfaced, waterpump, and one pass. side axle, $200 Dyno time, $50 Random stuff. So, I am doing all the work myself except for the exhaust and maybe I might pay for a good IC piping setup. If you look around you can find deals. I found an emanage and support tool for $235 which I just traded for a SAFC II and $50. So I pretty much got an SAFC II for $185. Thats $100 cheaper then ebay. So look around. Deals come around.
