Anybody have any parts to sell for a lonely lsj looking to do the swap?

Haven07

Quick question, do any of you guys run a BPV over a BOV? And mind sharing your set-up?

Most LSJ-T's will run a BOV. Just google image LSJ turbo and you will find lots of pics.

I was looking at the zzp and ottp turbo kits and I saw they ran the Tial BOV. I was just wondering because from what I read it's best to recirculate the pressure back into the intake after the maf and was considering going that route. Thinking doing something like this :

That's an lnf... My maf on my zzp kit is a couple bends before the intake manifold. Nobody's got time for recirculating anything on an LSJ turbo lol

Haven07

Yea I knew it was a lnf lol and where the hell is the maf on a lsjt?

It really depends on the build. Mine sits close to the stock location of an LSJ maf just in the charge piping.

You only have to recirculate if the maf is before the turbo. Move the maf on the LNF and you can run an atmospheric vent.

Haven07

Ahhh I just assumed the maf would be relocated like it in in the lnf picture

Good evening fellas I own a 08' balt tc and have added injen CAI and piping and get CEL P0100, i have to have a tune in order to fix maf code correct?

I ran a draw through and a recirc hks because I don't like the way most mini-afcs screw with the maf signal makin it choppy. I run a 3.5" housing.
But then I switched to sd anyway.

I'm running my maf pre-turbo with no recirc without any issues. 3.5" housing, no mini-afc. Don't know how it works but it's fantastic haha.

Sd?

and out of fuel again. time to revamp the whole system

Whats the current setup?

aem 320lph with a k.b. boost a pump (20v 40amp) 160lb bosch injectors on E85

Have you monitored fuel pressure to redline? I have seen quite a few of the 320 AEM pumps with bad pressure relief valves drop pressure up top. Had it happen to me when I first went turbo, and would barely push me to 500whp with 1200's while going lean and maxing the injectors severely.

in addition, I kept sucking the fuel canister assembly dry. once the surge tank was added, the problem went away

450 that bitch. stop ******* with aem ****.

I got rid of my faulty 320 for a 450 and then went with the 160's. Made it to 650whp so far and still had a little bit of fueling left.

450 will probably be the next upgrade since it's easy swap and wiring for the bap and all is in.
but finally put a real functioning boost gauge in and I've been running 31-32psi not the 25-27 I thought lol.
so that explains the high fuel consumption.

and just got this setup going this weekend. gonna have to wait til I get on a dyno to see what the fuel pressure does as all I have is a gauge on my rail.

but it stays at a constant 92% up top as the bap kicks in (boost comes on fast so idc's spike before the voltage to the pump jumps to 20v) right now it's set to come on at 6psi, but once it spools it's at full boost pretty quickly.

have the return line dumping right into the canister without that restrictive grey fitting anymore (just a straight hose into the canister) so I don't think that's my problem. Just pretty sure I"m out flowing that pump even at higher voltage.

also this 320 is only a few weeks old as my other one exploded.... yes exploded.


car isn't going lean yet holds a solid 11.3 afr so far to 8k just idc's are showing higher then I think they should be on 160lb injectors (base fp is 43psi btw)

Well the high boost may contribute to the higher IDC's a bit But I bet it pulls nice lol

Doesn't sound like the pressure is falling off too hard. Mine was very noticeable in the IDC's when the pressure would drop as duty cycle would sky rocket to try to maintain fueling. However you will likely have to run a bit more base pressure on that 320 to push much further. The PRV opens around 85 psi and should maintain that on a healthy pump, however it may drop a bit if the pump isn't keeping up with the fuel demand. The PRV on the 450 is supposed to be 97 psi. What I did before I had an in cabin FP gauge is I took a cheap little camera I had and taped it up under my hook with a light shining on my FP gauge on my regulator. Then watched the footage

If I decide to go a little bigger on the turbo side of things this winter I may consider a KB boost-a-pump on mine. My fuel pressure drops off just a bit on high boost in the high rpms. Feed it more voltage lol

oh she pulls like a beast, even on star spec's. spins hard in 3rd but I can get it to keep pulling.
was wondering why it felt so fast lol.

and from what I can see it seems to hold pressure (according to the logs) so not too worried about it right now. probably swap in the 450 in 2 weeks when I have some free time again. and go from there on what to do next.
still haven't hooked up the nitrous yet lol.
