Back at it

[blackawdtsi]

Put some new shoes on the girl and got around to taking some pictures. Not the greatest pictures but at least there's a little eye candy in the thread now.

[blackawdtsi]

I got sick of the metallic Kttsssssssssttt the Greddy Type S BOV was making. So I bought and had MAP mount a Tial Q for me today. Unfortunately it still flutters on low boost so I'm going to try a dedicated vacuum source to see if it helps.



Still can't decide where to go with the car. Do I leave the Holset on and get BC BR coilovers or do I get another turbo? First time I've had money before I knew what to do with it.

[goodhart]

Dude, I don't know if you realize how much this turbo has left in it. lol

Bring it to Shane and turn the boost to 40psi. Then think about getting a bigger turbo.

[turbotalon1g]

^Tell us.

These holsets really seem to shine over 30 psi though.

[blackawdtsi]

Yeah you guys are right, other than knowing other people have hit 6xx DJ HP I really have no experience with them.

But my experience is usually more boost = more problems. I'd rather run lower boost and have less problems. Which reminds me I still need a twin disc heh. The 2600 / street disc definitely won't hold on at 40psi.

[goodhart]

Well, if my brother ran a HX35 at 50psi and an HX40 at 65psi....

Also, more boost in a smaller turbo really isn't that much different than less boost in a bigger one. Just flows the same and makes it laggier. 25psi in a 14b ain't the same as 25psi in a GT35R. Ya know?

[turbotalon1g]

ON a dsm?

[goodhart]

Nope. But it was still on a T3 HX35. Just saying, you can run a ton of boost through those things.

They are diesel turbos... The last thing I'm worried about is blowing the turbo. When I said more boost causes problems I was referring to the motor and intercooler system. The catch can doesn't remove crank case pressure and to be honest I'm iffy with this motor since I didn't build it. I don't know what anythings torqued to or if it even was. Not sure of the walbros will keep up an high psi either.

[blackawdtsi]

Time for another update.

I got sick of the Greddy crap that I have to calculate to know where I'm at. So I replaced the boost gauge with an old Stewart Warner I had laying around and replaced the EGT with an AEM UEGO. Still need a different oil pressure gauge though.

I also bought one of the GrimmSpeed MBCs. I really like it, I like that it has audible clicks that indicate .25 psi change in boost. Even though you can't hear them with the motor running, it's better than an entire turn of the knob for 1 psi. I think vertical lines instead of horizontal lines would be a good idea. They're more precise. It's not like you'd be able to replicate boost using the current horizontal lines. But thank you DC and Jordan for talking me into it.

I also did a boost leak test and had a pretty good leak from the intake manifold gasket. So I replaced it with a paper Fel-Pro one on the side of the road last night. Big mistake. The paper didn't stay straight when seating it, if I hadn't been in a rush it wouldn't have been a problem. So I went to First Gear Garage and replaced it with a metal OEM one today. I know I fixed the leaks because the car dies shifting now . Will need to adjust BISS and do some tuning soon.

I've been at a real 26 psi for a while now after the MBC install. Definitely feels like a gained a few horses. Will hopefully be up to 35 soon and will dyno again.

I decided to ditch the 255 intank / 255 inline setup also. I'm going to run two or three DW 300s instead. I have big plans for this car for next season and have started collecting parts. Including these Wiseco 7 bolt 10.5:1 HDs.

[blackawdtsi]

And thanks to the wife for helping support my addiction.

Nice. why did u change pump setups?

I take it the current motor is a 7 bolt?

Newer tech for fuel.

And no, the motor isn't 7 bolt. The Wiseco HD's were off the shelf 10.5:1 CR. If you look at the 6 bolt pistons they're only 8.5:1. Both pistons are the exact same dimensions omitting the CR and wrist pins. The 7 bolt pins are 1mm thicker than 6 bolts also. So I also get 1mm thicker wrist pins in 10.5:1 off the shelf (yes MAP had them in stock) at the cost of drilling out my rod bushings 1mm.

[turbotalon1g]

I see.

I know about using those rods, just wondering if u had a 6 or 7.

[blackawdtsi]

Bearings decided to eat themselves.


Time for a new motor.

[blackawdtsi]

I took advantage of this decent weather and tore my oil pan off today.

While poking around the car I found this, which I was told was hooked up:


And this:


Considering all of the I/C piping was also loose; I'm going to go over the whole car before it leaves the garage again.

Anyway, here's what was in my oil pan.


And I bet you can't guess which one was spinning haha.




Even though the bearing looks like it had a bad night in gitmo, the crank is surprisingly smooth. If the one rod wasn't blued from heat, I would throw another set of bearings in and see how it went.

I didn't have enough time to pull the motor out today but at least I know the situation now. The next decent day I'll get the motor out and send the rods out to be reconditioned and crank to be cut. Hopefully the crank doesn't need to go past .10 under. If it does, I won't be running it since DG Motors wants $180 to re-nitride it and who knows when I'd get it back. I have a nice OEM crank I picked up but I was trying to save it for the next build.

Will update when the motors out.

[93gtpeater]

Sucks you spun a rod bearing on the new car. I guess its a good thing that happened too. You got under the car and found some things wrong. Hope the rebuild goes smooth.

[blackawdtsi]

Yeah unfortunately it requires my car to be down for two weeks.

[blackawdtsi]

Time for another update. I got time to work on the car yesterday. Everything's off except the motor mounts. I also put together a new motor hoist. Nothing too exciting but I'm getting there even with a lot of days between me working on it.

[blackawdtsi]

Put together my motor stand and got the motor out.

I had decided since the passenger axle didn't want to come out; I was going to leave it in and rip it apart.....



Damn thing stayed together! I ended up prying it out at a nice open angle since it stayed together with the motor literally out of the engine bay.



Will get the crank and rods to Wagamon tomorrow. They said 2-3 day turn around so hopefully Wednesday she will be running again!
