lol Sorry Eric, but I can't razz your skills, so I have to pick something.

Running Vic's old turbo probably won't bring me past 250hp, it's a pretty small garrett. I have a garrett t3/t4 sitting in my garage that needs a rebuild, but I might scrap that idea and go with something bigger, really depends on finances. Shooting for big boost will probably be next winters project.

 

Good deal. Get used to the car on this setup. Everything but the turbo should be able to hold a decent amount more power so it should be interesting to see what you do.

 

Just a little update. Over the past few weeks I've been picking away slowly (VERY slowly) at this. Today I finally jumped on this and spent the whole day finishing up the electrical and other little things. I have all of the electrical completed, installed my newly painted calipers, painted my gauge pod, installed both fenders, modified and installed the bumper, did a small modification to the bumper cover (removed the grill), wired and installed the steering wheel (what a f***ing pain in the ass, seriously, they should make an aftermarket clockspring). I believe the only things left electrical wise are running a wire from my engine fusebox to the oil pressure sender, and the greddy turbo timer. Only other major thing is to reinstall the vacuum lines once I get my manifold from tanc, and then I'll just bring the car into my shop one day and use the hoist and mig welder there. Preinstalled the APE traction bar bracket, just need to weld the brackets onto the control arms.

I'm putting insurance on it for July 1st. If I get the vacuum manifold by friday it'll be running next weekend, otherwise the following weekend.

A couple weeks ago while trying to remove the oil plug in the head, I ended up cracking a chunk off the head. I ended up filling it with lab metal from Alvin products. We've used it at work a few times to patch oil pans and stuff, we'll see how it holds up to a bit of heat and pressure (says it's good for up to 400 for 20min so it shouldnt be a problem).

Once it's running on its own power I'll throw in the 440cc injectors. Still waiting on an FPR to install the walbro 255.

 

It lives! Unfortunately it already needs surgery.


I ran it long enough to tune the fuel a bit. Still have major idle surge issues, but I'm pretty sure it has nothing to do with the IAC, and more to do with the fuel and spark advance tuning. I took a vid and a bunch of pics that I'll post this weekend. I got to actually run it and see how the engine responds.... It is LOUD, but mostly due to my many many exhaust leaks. Got to hear the BOV a few, and watch the boost gauge go up to 7 PSI. Found out I have no (very little) brakes.

In my last post I mentioned a cracked part on the head. Unfortunately due to the location of the damage, I wasn't able to clean it good enough, and my patch job leaks where the new piece meets the wall of the original. Not spraying oil, but it creates a steady drip. So it looks like tomorrow I'm going to have to pull the head. I could flip it over and do another patch job by cleaning it properly first, but since I'm pulling it I may as well just find a good TIG welder to do it right the second time, I don't want to have to mess with this again.

So that is where I am. I noticed that when I was revving it, I didn't really hit boost until around 5k rpm... Is this normal for a small turbo like this one? (I was under the impression that small turbo = quicker spool). I am sure I have a couple of boost/vacuum leaks as well, but would it effect it this much? I have to read some Corky Bell on boost/vacuum theory I think.

Anyways, thats where I am now. I was hoping to take her for a ride this weekend, but looks like I'll have to wait until minimum next weekend. 02.gif

 

Don't know what turbo you have but spooling only at 5k doesn't sound right at all.. My t3 super 60 spools up easily around 3000rpm

 

So I figured... I'll have to take care of my boost leaks before I start tuning this then.

 

Wait if you're not running it how do you know when the turbo spools up? If you are talking just revving (no load), it will barely spool up, at any rpm..

 

Well... then I guess that would explain some things... lol

Here are some pics from today. Got the head off, took 3 hours.






So from this, I broke a bolt off in the turbo, and am assuming that t4turbotiburon was running lean in one cylinder. (this was his engine)

The first pic is the damage to the head, I don't have a pic of my patch job but it was decent.

Anyways, this is where I am now. I'm assuming that it's OK to run with the cylinder in that condition? I was thinking of taking a dremel to the scored part of the head and smooth it off, but would this create a significant difference in the volume of the cylinder? I'll probably replace the piston next winter when I rebuild the turbo system.

 

That 1 cyclinder is eww....

Just wire wheel everything dawg. fing02.gif

Wouldent use a dremel..

 

Well to make a long story short, this project is going back to square one. The engine was f***ed from the beginning, and due to takign a shortcut, I bent the valves in the head to pretty much seal the deal.

Now I have a new plan of attack; one piston was pretty much toasted, and took the cylinder with it. I'd rather not have to deal with more issues with this motor, so I'm going to pull it, take the knife edged crank and the rods, and swap them into either a: my old block (about 60k on it) or into a beta 2 block. Either way I'm getting a beta 2 head, but I'm thinking I'll be better off with the beta 2 block anyway. Only question is will the crank swap nicely?

I'm going to pull all the parts I want, pick up some ARP rod bolts and head studs, and drop it all off at a local machine shop (mainly so they can install the crank and gap the piston rings and hone the cylinders). All this trying to do it myself crap has taken more time than I'd care to calculate, so this is one area I'll feel comfortable paying someone to do it. I have a brand new set of ross low comp pistons I've been trying to sell since I got the built motor, and it's a good thing I didn't sell them cause I'll use them in this build.

So all in all this motor wasn't a total loss, I did get a nice crank and some built like a tank rods out of it, unfortunately it added 6 months to the project time.

So my new time to have this up and running; May 1, 2010. I'd like to have all the parts required to go to the machine shop by the end of November.

Also I'm going to sell Nightshark's complete turbo kit and start that from scratch as well. Only thing I'm keeping is the exhaust (will probably sell the DP to go with the kit though). I was going to rebuild the turbo system for high boost anyways.
