The manifold will be flipped 180. The balance tube (small one in front) will then be at the rear giving me MUCH more firewall clearance. I can probably move the engine back quite a bit because of that. The larger crossover tube, (that the stock TB bolts to) will be removed and two throttle bodies put in its place. Those TBs face the front of the car. Did you see the pic of that mock-up? It will be OBD-2 using a factory v6 ecu from -something- with a piggy-back FIC for boost engine management. The FIC can clamp the factory sensors (maf/map/o2/etc.) so the stock ecu thinks everything is fine and dandy while the FIC is in control of fuel and ignition under boost conditions.

It will be AWD so hopefully it'll stick. It'll really suck to loose this thing. It's not drift friendly. It's hard to hold a drift even in snow. It's to short. The EVO 10 500hp guys are already saying they won't race it. :( They say it's too light and will be too fast. I can only hope.  >:D

That is reason enough to try ???  I have watched the Subaru vids, and it is impressive what they can do.  Not sure of HP, but when you can easily light them up. it is more controlable.  It will take lots of practice.  I am still learning to control the impulses.

Running AWD, with an Auto?  Or did you get the 2.5 with a 5 speed?  So far I have only seen one 2.7 with the 5 speed, but it means they did make them.

The sump would look like this... And also a pic of the T51 version of the H2xA engine. Looks sexy. They made their own pan for it. That reduction drive is also a nice piece of craftsmanship. Why would they go through that effort without knowing this engine had great reliability? I have high hopes for it.
The weight per/hp is very good, and that is considering the 2.5.  The 2.7 should be much better.  I was talking to one of the 2.5 converters, and he didn't know they had a 2.7 version.

You know the Aerio 2.0 puts out 155 stock (30 less than the 2.7) and it is a much easier fit, especially if you have some of the parts off the Tracker 2.0.  Depending on the boost it would also make your X-90 fly.

I'm staying with the 2.5L for a few reasons. It's a v6. Although 2.5L is small, it's that much more impressive to be stuffed into a little car. The sound. v6's have a smoother purr to them. The Suzuki v6 has so much going for it in terms of strength. Forged internals, closed deck, 2pc block, huge head ports considering it's only 416cc a cylinder. Also the 2.5 should have a little more meat in the cylinder walls because all they did was bore it to get a 2.7L.

If I went with a 4cyl it would be a Nissan SR20DET or Mazda BPT. In all honesty I don't have much faith in Suzuki. I've see far to many scattered around junkyards in the 100-150k mile range. I wouldn't waste my time trying to make power with one of their 4 bangers.

If Mazda had an AWD 5-speed drivetrain that would fit in this car, it'd already be in there. This Suzuki stuff is costing me a fortune. Feels like I'm moding an Audi with the cost of parts. :o

Have you started fitting that turbo yet?

No I'm still gathering parts and fiddling around with it. I cut out the bumper and got a Supra intercooler for free and trying to find rims because my adaptors don't work with the drive flanges are installed. :( Other then that I'm kinda screwed finding a singlemode transfer case because the canadian seller won't get off his #u(king a$$ and take a picture of the case for me to verify it's single mode and I'm not dropping 250+260 shipping for the wrong part.

I've also been tied up with this damn Nissan I picked up. It's a 2000 SR20DE Sentra SE with 88k on the clock and turbocharged. I sold my ZR2 for $3500 and nabbed the Nissan for $1500 because it had a knock. I tossed a bearing in it to get me by for now until I can build another engine. I'll still have a daily driver (alot faster then a Tracker) and another $2g towards my X-90 project. It's a very nice looking car otherwise. Win-win except for the fact that too many "mechanics" have had there hands in it. Everything I find wrong with this car is wrong because someone did it wrong. On the other hand I didn't exactly need another turbo import project. lol It's distracting me from making real power in the X-90. :D

We have been refering to the Nissan as the "tuner casserole" because there's so much shit thrown into it and it still sucks. I hate casseroles! >.<

I better post to keep this thread alive. :)

The only thing I've managed to accomplish are the turbo rebuilds and the dxf drawings of the turbo flanges to be jetted out of 3/8" plate. My mock-up block is still sitting in my frozen garage. I didn't even get the heads out for flow testing. I've just been swamped with work and it's too cold to work in the garage when I do have time. Damn you winter!

I did finally find a good deal on a building to get the shop going so look forward to alot of progress this spring.  ;D
