MR2 Project Update *pics*
So last night my buddies and I were working hard to get the MR2 back together for the first race of the season this coming Sunday in Barrie.
We rebuilt the T3/t4 turbo with new seals and bearings and installed a set of dsm 450cc injectors. Last night we basically just put it back together and fired her up for the first time since we put it away in the fall. It litterally fired up the instant it cranked over! Ran beautifully, and no leaks what so ever!
It is hard to see in the pics, but we decided to try a different bov. The bov we had been using was some cheap ($70) ricer bov which was giving us bad compressor suger (chattering) and as a result, poor turbo response on quick-shifting. The bov we got to replace it is the factory unit from a porsche 911 turbo. Thats right! And it only cost us $60 shipped, brand new. It's made by bosch, it's plastic and doesn't look like anything special. But it is. It's a synchronic bov, which means it actually stays open until boost hits, then it closes (this helps with throttle response). And when it opens, it opens quick and smooth with absolutely ZERO chatter or fluttering. Just a quick wide open PSSSSSHH!!! perfect! 60 DOLLARS!!! Screw those $200+ name brand bov's!!! lol. So a little tip to all you guys building turbo setups; you don't always have to buy the most expensive or most well-known components to get the best function.
Here are some pics:
Behold, our little shed where all the magic happens...
:
Owner of the car, Tim, feeding it some fresh oil:
The trunk lid, aka tool bench...lol:
Yes, that's alcan aluminum foil, which we used for the oil drain flange gasket on the turbo (we lost the gasket when we rebuilt it). It works great!...No leaks. We simply cut out a few layers and matched them to the shape of the flange:
A shot of the engine bay and the XSpower water to air intercooler and the $60 bosch/porsche bov:
Some tools scattered all over...and Jeff on his blackberry, being very helpful...lol:
Tonight the steering rack comes out to be inspected and hopefully fixed...
That's all for now. More to come soon...
Thanks for looking.

Awesome ride man. I remember watching Young and Dangerous and this dude steals a brand new at the time MKI MR2. It looked sexy and they still do.
The BOV from porsche, did you order a brand new item or got it from some scrapper/wholesaler?

So last night we input the new data for the dsm injectors into megasquirt. It immediately ran better. Turned the boost up a few more pounds and adjusted the acceleration enrichments to sharpen up the throttle response...Will have to spend some more time later for turning up the boost more and doing a proper re-tune.
With regards to the steering rack, turns out the rack is fine (we didn't even take it out). What we found was the oem upper front strut mounts are very spongy and need to be replaced.
....It never ends! lol
But that's half the fun!
Took her for a spin, still goes like a bat out of hell...can wait to turn up the boost and re-tune!

We work on the car so often that it becomes a bit of a hassle to document everything, with either videos or pictures...lol.
We've now bumped the boost from 10 to 13psi and did some minor tuning. Took it for another spin last night...it's getting rediculously fast now. We really need to get it on a dyno to see what it's putting down. hehe.
I will take some vids soon and post them up for shiz!

Turns out the steering rack is fine, but the soft oem upper strut bushings are not...lol Going to replace them with solid units.
Boost is now up to 15.5psi...did some tuning last night...running prime!
Running into some traction issues now with the street tires....lol
