Official Turbo LSJ thread!!!

I have a set of k1 rods if you need some replacements. And a set of diamond forged pistons as well.

Basic. It's an LNF block with LSJ internals; JE Pistons; P&P head w/ ZZP valve springs.
I'll be sticking with my HP5558e, but I've been thinking about dropping to the .48A/R turbine housing so that I've got wicked fast response time and a thick mid range... but I'm still undecided on that. I'll still be using the Vulcan Intake Mani that I've always had on the car, but I'll most likely be going with the Treadstone Turbo Manifold.
If I stick with the .63A/R housing, I'll probably keep it on a tame 25psi... if I drop to the .48A/R, I'll shoot for 30psi. Either way, I'm not really looking for a number, so much as a fun, nimble, responsive car. It should make low to mid 400whp/wtq though.

Ok so I'm having a few issues with my turbo swap. I have pieced a zzp turbo kit together but I'm running custom charge pipes and intercooler. Ive placed the bov and maf sensor in the cold side of the intercooler piping. The car surges at start up and no matter what we do in hptuners we can't get to idle correctly. It wants to and the only way we have gotten it to idle correctly a few times in 3 hours is to fail the maf and run no timing. Other than that it keeps bouncing between 1-2k. I wish I had some screen shots of the logs but I have nothing. I can't find any vacuum leaks noticeable and put fresh plugs (bkr7eix) at .32 in. I had to do a case relearn on it to because the computer swap I believe(swapped with a friend because I was trifecta tuned), but after I did it the code went away. No unusual codes now except a throttle body performance code which hasn't popped up in awhile. It registers and responds correctly in hptuners.
Any ideas?

zzp and hahn both put the blow off valve about 1-2 feet down the charge pipe before the intercooler, this keeps flow issues away from the maf. Maf is also reading temperature and mass air flow obviously. If the BOV is located close it can cause it to read in a non-linear fashion. The BOV should also be located closer to the turbo so as the car goes into vacuum it lets the pressure out near the turbine and in practice helps with a lot of boost issues. (boost creep, surging, blah, blah).
I havent had any issues with my setup in this configuration all the way to 28 psi and run it daily at 24.

more like under vacuum the bov is staying open and its pulling unmetered air in through the bov rather than across the MAF. That would be it.

maf should be in a good length of straight piece of pipe about 2 feet from the throttle body. The BOV should be before the intercooler but just after the turbo about a foot or two from the turbo.
#6092
Yeah its in the zzp maf housing which is about a foot in length. Add the couplers and its about 18 inches

never dynoed the car but on 26psi pulled on a vette on a 150 shot of nitrous pretty badly. 3 times. After the back to back pulls was when i heard the rod noise. found a good source on rods, but since i have to tear her down i may just install the sleeved 2.1L block that ive had for a while now. My diamond psitons that were in the car are fine rod was tweaked a little, cyl 3 was 130 psi and cyl 4 was 180. 1& 2 were at 220psi which is were they always were

Did you get your valves fixed? Or did you just swap on a different head?

Came back to home to it in January 2010. Bought a new turbo and turbo manifold in May. CED in June. The car was at ZZP a week or so later getting the custom charge piping and Return Fuel System that was on Ryan's car (wasn't offered for sale at the time).
And then melted the piston in late November 2010. It's sat around since then. Having other fun cars has probably been the real motivation killer, along with buying just tons and tons of other fun things... like firearms.
