Time Slips
3/01/05 Put together a 393w with the same Vic jr. heads and some JE pistons and a carb this time.  No times slips yet.
8/10/03
Running again, best times so far are 6.60's @ 106 and 10.50's @ 135 with 13-14 psi.
6/01/03
I have decide to go with a 351w that I had laying around. It is a stock block crank and rods. I had some used hypereutectic pistons with 22cc dish, that will work for now. I went with some Vic Jr. heads that were cc to 70cc thanks to TEA . That gave me a blower friendly 8.25 compression ratio.

5/13/03
Been awhile since the last update, the 302 was getting pretty tired, with 147,000 miiles I was beginning to get some pretty good blowbye to say the least. I found 5 callapsed rings upon dissassembly.

5/23/02
New  timeslips 6.99 1/8  @ 102.60 and  10.99 @ 116.20 1/4 with 15psi. It looks like the tranny needs new clutches, as I shifted into high gear the tach went to 6500 and it never moved, as you can tell by the slow 1/4 mph I had to let off, but it was still my first 6 sec 1/8 and 10sec 1/4 mile  pass in the car so it wasn't all bad.

Added  new pictures Turbo pics

3/31/02 Finished up installing the roll cage, C4 with transbrake and 4300 stall, 31 line spool and axles maybe it will 60ft.. I also boxed the upper and lower control arms, welded the torque boxes and replaced the bushings. I am going to try a MSD 6BTM boost timing contol we'll see how it works. Hopefully some track times soon!!

2/28/02
Just thought I would update the website, I pulled the trans and found the splines on the torque converter were stripped, I inspected the C4 and it is fine. In my search for a new conveter I ran across a complete C4 with transbrake, 4300 stall, SFI shield etc. I will most likely be putting this unit in the car. Now the search is on for some good axles and spool. I will putting the tranny in as soon as I finish up on the roll cage and hopefully get back to the track by spring.

11/10/01 Just an update on the turbo project, I made it back to the track about three more times since 10/16 and I must say it has been nothing to brag about! I blew off a few lines (the ones I didn't crimp) blew a couple of turbo flange gaskets (should have used a metal style gasket) and had to reweld the headers in a couple of places, nothing major.

NEW UPDATE 10/16/01 TRACK TIMES!
! After two bad passes a week ago from heavy detination I made it bad to the track with some good gas. Here is the timeslip and man was I surprized! 7.02@104.60mph 1/8 mile, note the best the car had run pre-turbo's was 7.80@88mph the increase in hp is more than I ever expected this early on, the pass was very smooth and just continued to accelerate hard all the way through definately a 6 second capable car and looking for 10's in the 1/4@130 mph 60ft times were on the slow side 1.75. The car could use a transbrake bad, I need to be able to spool up before the car leaves.

9/28/01 
Just got back from my first test drive, I would have never thought two little turbo's could make so much noise, it sounded like a tornado under the hood. The car feels like it pulls really hard, much harder than the same motor with 150hp NOS. If its turns out not to be a bit faster it is all still worth the time and effort, just the sound the twins make as they spool up and the horrific whooooooshhhh from 3000-6000 made it worth while.

9/26/01  It Runs!!
After a couple of weeks of thrashing I managed to get the car running. Still alot of tuning issues to work out. Can't wait to make a pass.

9/15/01
Made a trip to the local Semi salvage yard, picked up a bunch of mandrel bent piping and silicone hoses and clamps, if your looking at the budjet buildup this is the way to go. I also acquired an intercooler but was unable to make it work.

A tip I picked up of the JYTurbo list, bend the ends of your pipe this will keep them together under
boost.
9/7/01 Managed to get the C4 Trans in the car this week, just a note to those switching from a T5 to a C4 the trans mount for the T5 mount will have to be modified to work with the C4, the C4 sits about a 1 1/2 closer to the front of the car. Just grind the cylinder mounts loose from the main mount and slide forward and reweld.
Slip the cylinder mounts  forward and reweld
Grind the tack welds

Making a little progress, sure looks alot better than it did.
8/30/01
Just an update on the project, the transmission is back together, just finished painting under the hood, I have decided to go fuel injection, I purchased a used 75 pro m and 36lb injectors, and a new TFS-R intake. I know have both headers completed and I will be putting the motor and trans back in the car soon, still working on mounting the intercooler and plumbing from the turbo to the IC. I have also decided to try water/alcohol injection along with the IC.  The picture below shows the rough placement of the twins. I've since removed the motor to clean and paint under the hood
7/14/01

Well finally got around to tearing into the C4, other than the valve body being pretty dirty it was still in pretty good shape. I ordered some raybestos blue clutch plates for the front and rear drums, new bands and seals, I also decided since the valve body was in such bad shape to goahead and order the PA reverse manual VB. Purchased a used TCI streetfighter 3000-3500 stall for $150 off ebay. With help I'm hoping to have the tranny back together by next weekend.

As far as the motor goes I am leaving the same combo, Ebrock heads (6025), E cam, the motor does have a new crank but its still standard bore with stock rings an pistons (145K) but the compression is still good, I sure it will have plenty of blowbye, well see how it does.

Finished the oil pan drain lines, I cut a 3/4 hole in the pan (make sure this hole is above the oil level or it will not drain) and welded in two pipe nipples
In the picture below you can see the oil return, I welded in  a 1/2 npt steel coupling.
07/5/01   Still gathering parts for the turbo project, I now have 3 Garrett T03's with .63 ar's, I have a set of Flowtech shorty headers that I will be flipped point toward the front of the motor. I will be using a old C4 thats been in sitting around for the past 15 years waiting for a new home. I will be making my first attempt rebuilding a automatic trans.
6/14/01 The Junk Yard Twin Turbo Project Started!
