stare in awe of B6 power

Once I get the hang of how to use the haltech data log viewer I might actually hit triple digit power

Your lean area at 5000rpm corresponds with the dip in horsepower.

Thanks for the tip.

I attempted to work on the map some more tonight but it spat the alt/waterpump belt off. The FD alternator appears to be offset ever so slightly. I'll tackle that tomorrow and get back to the action weather permitting

car has been performing pretty flawless the past few weeks so I ordered the rest of the stuff to go turbo this evening. Hopefully it all arrives by end of the month so I can get a wastegate tune done before the season starts end of feb.

I see that people run into boost creep with a 3" exhaust....wonder if I should waste time porting the wastegate port on the turbo

Mounted turbo and manifold up, plumbed the coolant and oil drain. I am missing some fittings to do the oil feed.


Shot of the lower coolant hose and oil drain


Had to pull the front covers and timing belt off since it seems the front main seal wasn't installed properly.

I am welding up the end tanks for the intercooler as well but to be honest, me being a noob and 3/16 being at the upper end of what my welder can do, it's not coming out as nice as I would like. No pictures of that until I hit everything with the flap wheel

I will probably take it out, the motor is bad and I have 0 ambition to try and find a replacement

My angle grinder died and the hand file wasn't working out so hot to finish the oval hose. (the 90* needs to angle outwards hence the need for an oval.


I hate thin aluminum. I get about an inch of decent weld then the arc goes nuts. Probably didn't sand off the polish enough.


Thicker cast is yummy


Finished the down pipe and tacked together the mid pipe. It looks like it's hitting the subframe but it's just hanging down a bit. I did it this way to clear the Autoexe rear under brace whenever it arrives.

The muffler i got is a little too long and using a 45 off the pipe by the diff points it at the tow point. I am trying to avoid going left to U turn right. Might try a 90 and see where I end up this weekend.

one of my better looking stretch of weld on the intercooler. I am getting the hang of it but most of the welds that join the sheet metal together need flap wheel jesus before i post pictures

Good progress!
I found welding random bits of aluminum together to be problematic.
Welding pie cut sections of the same pipe was waaaaaaay easier.

It seem's my welder and I can weld any aluminum other than the thin tubing. The arc just kept jumping around and not making a puddle.


So I said **** it and pizza sliced the **** out of some 2" 409 stainless I had laying around. Ran out of gas so I had to use my mig, which meant grinding down all the pebbles and trying to make the pipes look presentable


Cut and bent actuator rod to clear the coolant fitting


I need to re-route this brake line and wrap the downpipe


The NPT thread stripped out because aluminum so I welded the 90* adapter in. Black anodizing turns that doo doo gold color from heat.


dat jdm side exit turn down. I have many welds to finish once I get some argon

money shot. I need to make 2 more mounting tabs for the intercooler and add the BOV port and a 3/8npt port for the IAT.

Injector connectors are getting swapped this weekend to EV1's for the evo 550's I have. A friend donated a denso fuel pump meant for an RX7 so that's the fuel sorted out.

It is pretty common to cut the shelf up underneath where the heater core hoses come out. Structurally it doesn't effect much. You can come all the way over to where the steering shaft comes out. It makes you huge difference for routing.

I was thinking of doing that but I should be able to bend it to clear and toss some gold tape on it. Trying to avoid cutting for the moment

Fucked up on the BOV port. I need to angle it down a bit to clear the filter


IAT position

Plan is to do a boost leak test tomorrow to make sure everything is sealed tight and then start on finishing the exhaust.

Welded up the exhaust. I need to weld up the v band on the end and the muffler to complete


Bent the brake line to get some more clearance. Think that will be enough with once its wrapped?


Forgot the bung at home so didn't get to weld that up today


Angled the DV down so it clears the filter. Picking up the hose to connect it tomorrow


Shot of the oil feed. I'm using -4AN with a 1.5mm restrictor fitting on the turbo


Evo 8 560's with new quick disconnect connectors


Intercooler pipes painted black and looking 1000 times better

My new gates racing timing belt and front main seal are scheduled to be on island by friday. Fingers crossed for start up next saturday

Mission complete!

I took 0 pictures cause...well they would look like the rest of them above. I thought I added more tension to the actuator after I cut it but max boost was 25kpa

I'll buy some 1/4" spacers and new bolts tomorrow and shim the actuator to see if that gets me to the 8psi goal

Thanks!

Right now I'm trying to figure out why the boost is so late. I think it's because I didn't put enough tension back in when I modified the actuator rod. I'm going by the hardware store to get shims and extra bolts now




(i know the fuel needs a ton of work)
