OK heres how she looks right now



Right now all we have for exhaust is a down pipe, the arf guage is acting quite irratic, could it get affected by wind being that it is fairly close to the end of the dp? It has been pretty windy here the last couple of days and I noticed the wind will make the guage react without the motor running.

Yes... you are experiencing reversion... you need at least 12 inches of piping after the sensor to prevent reversion from messing with your AFR readings.

Yeah, nothing major we have been working quite a bit and haven't had time to get a piece of pipe for the exhaust.
But this week was just putting the interior together, running wires and hunting down bolts and clips.

OK update, new brake calipers came in yesterday going to get those on in the next couple days. Also went and got a couple feet of exhaust pipe so we could check afrs more accuratly. It idles at around 11.5 afr. Which sounds good to me.
Now how do I go about checking the rest of the rpms for afr's without possibly popping the motor?

I idle at about 12.0, doesn't like much leaner. I his low 11's to high 10's at full power. Cruise at around 13-13.4 but it responds to 12's in an instant.

Hawk pads work well, but i would see who has something in stock that will ship promptly, perhaps respeed.

Might want to order some winter tires for the test drive if you don't finish soon

Ok new brakes all around and she was ready for a ride!
This little turbo really wakes this motor up, pulled hard in every gear.
Afr's seemed good hitting 10 on full throttle 13's on cruise and 11's on idle.
The tach stopped working but it would hit the 7500 rpm rev limiters on the msd's pretty quickly.
Still gotta get a boost guage too.ost
I will pome vids when I get a chance

I picked up the complete kit from another member here on the for sale forum, you will have to keep your eyes open for another used kit.

Picked up a set of 15" rotas from a club member. Should be here at the end of this week. Gonna order some Yokohama advans probably in the new year for them. Goodbye + rims. John smack, buy my tires. You need them for your rx-4. They're 205/65/13

Oh, also picked up a 3" turbo muffler. Will get an exhaust system built some day. Also waiting on an oil pan gasket so I can re seal it. Gotta build an omp block off plate too.

Nice work.
I am starting to install a BAE turbo.
Do you have an oil cooler tucked under the radiator?
The radiator looks great.

I am originally from Nanaimo B.C.
