    L28, need a bigger turbo, which one?

    Well my current turbo is worn out. It has in-out shaft play as well as up-down. I've noticed max boost has been falling after nearly every run. I made several runs on 12-15-18, first pass max boost was 27psi, next two runs were 25psi. Then raced on saturday 1-5-19, max boost was 24psi. That's when i decided something must be wrong and gave the turbo shaft the wiggle test. Please explain the "quick spool valve". Thanks.

    L28, need a bigger turbo, which one?

    Thanks. The borg warner 177281 comes with an open .88ar turbine housing. I can't find one for that model any smaller. I had a .82ar on my tc4305 and spool was around 4500rpm which is a little late for 1/8 mile drag racing. The BG turbine wheel is bigger and would technically be heavier and harder to spin but it seems also that it would drive the compressor wheel more easily? I guess the L28 is too antiquated to find someone actually drag racing one with the BG turbo lol. So I guess I'll be the guinea pig. The 2jz and rb guys use them frequently but I don't think those engines compare. As for injectors yeah I just upgrade from 550cc to 750cc. Went from 95% duty cycle to around 85% so They may need upgraded again.

    I guess I did something right.

  5. Drag racing (1/8 mile), my current garrett tc4305 has worn out. Would like something bigger. I'm leaning toward a borg warner because I can get a new one for less than $600. Car is a gutted 280zx. Ford explorer 8.8" rear with ladder bars. Drag radials, th350 trans with brake hughes 4500 stall converter. Engine is mostly stock internals. 7.4:1 compression, arp rod bolts, mild port cleanup on the p90a. Isky L6 cam .540" lift 236 duration @.050". Has a custom built intake manifold and header, intercooler, ms2,..etc. The car has ran 6.74@99mph @22psi. And somehow pulled out 115mph on a test run. 60ft averages 1.50 but has done 1.45. I was looking at part number 177281 or 177283. I know the compressor will make the power but will it spool up quickly. My current turbo is basically a 60-1 with .63 hot side. Launching at 16psi and hitting 25 psi in .6 seconds. I can post up some datalogs. I just need to make sure the bigger turbo will spool up quickly. Thanks.

    Solid axle rear conversion info needed.

    I installed a 8.8" into an s130. There's a write-up here in this section.

    No more clunking when turning, no more whining. 4.11 gear ratio feels more responsive. A lot more solid feeling since there's no more rubber bushings.

    ford 8.8" solid axle swap

    Finally drove the car on sunday. Picked up a driveshaft from an explorer, shortened it and used a moog 290 u joint to install the chevy yoke. The rear calipers don't seem quite compatible with the stock master cylinder. Gonna need a bigger one. I plan on doing more test driving today.

    Finally making progress on this again. Fabbed my own crossmember instead of buying one. Cut out a section in the floor and welded it in. Welded brackets onto the rear axle. Made panhard bar brackets. This is a big job, wow. Everything is going smoothly though. Rear end seems to fit in the space provided there. Sorry this post is a little vague but I will answer any questions.

    No spark ms2 v3.57

    It should have a mica insulator. If not that could be your problem.
  12. Use Schneider springs 68022 110/240seat pressure and matching retainers. Then get the correct lash pads.
  13. Adding shims under the cam brackets doesn't effect the springs. What you'll need are thicker lash pads.

    No spark ms2 v3.57

    Ohm the wire from pin 36 on the db37 to the coil negative. If that's good power up the coil and touch the negative to ground and see it if fires. I that's good ohm all the circuits on the ms board for the ignition circuit using the schematics online.
  15. With high energy ignitions "they say" it's possible for a wire to arc to another wire and cause the wrong cylinder to fire. And spark blowout is when there's too much cylinder pressure for the spark to jump the gap on the spark plug. So you tighten the gap a little. I had it on my L28et. At 15psi it would start missing. I closed the gap to .025" and cured it.
