Turbo LS1 240z Build


Recommended Posts

Very Nice yessir. That was one of the turbo's I was considering. I still am actually. I also am interested in the new efr turbo's I think the 68mm (the biggest) will be to small though.

The track opens this saturday so I will hopefully have good news after that. I'm very excited.

I'm running custom tubular manifold. They might be up for sale soon.

 

Update from this weekend.

Well the day at the track didn't go as I hoped. But that's racing right. I can't remember if it was Aj or Erik that said it but "well you built a supra!" The car wouldn't build boost on the line to save my life. Even sitting on the t-brake it would only go to 2psi. Half track the car came alive and was a total monster. It trapped 138 mph but its still in the 11's with horrible 2.1 60fts. Testing the car a couple nights previously it would build 5psi without the t-brake. I'm thinking it was the cooler air at this point. Now I have to come up with a plan to fix the launch issue. Higher stall, N20, or maybe a turbo kit redesign. Better start saving my pennies lol.

I started a thread to get some feedback on my setup on ls1tech. This update is the result of that feed back. I'm trying to optimize my setup. I order a billet ptc 5500 stall converter. I also redesigned the turbo kit. My goals for the turbo kit were to get the turbo away for the t-body, make it a truly divided all the way to the turbine housing, down size from 3 inch to 2.5 inch crossover for quicker spool. I also wanted to be able to check my spark plugs without having to pull the manifolds and make it easier to swap a cam later on. I think I might even be able to add a filter now.

I still have to remount the coil packs and make new spark plug wires.

Sqc Tuning sponsored and hosted a local Import/Sport Compact Race. This was the debut of the new setup. I drove it up and down the street to put it on the trailer and headed to the track. Untested and I setup the 2 step in the pits, I took it for my first qualifying pass. Did a good burn out, footbraked into the beams hit the t-brake, boost came on instantly, lights came down car took off but the back end came out on me. I let off got it straight and got back in it. Clicked off a 10.7, Alright! The 2nd pass was the first round of eliminations. I got the left lane this time and repeated my process but left at about 80% throttle on the t-brake and got a 1.5 60ft. Run went smooth and clicked off 9.56. WOOT 2 years in the making!! Run #3 back in the right lane. I went 100% out the hole, backend came out again and I got another 10.7 but won the round. Run 4 and final round I'm up against one of my guys Mr. Neon. I give him lane choice. I get the left lane again. I launch on 80% throttle and pull a 1.6 60ft and get a 9.6 @ 147mph to Aj's 10.7 (his personal best to date - great job bro!). I won the All Out Power Adder class.

Eric, I just want you to know that you are the reason for the LQ4 sitting on the engine stand in my garage waiting to go in my car...

 

I didn't even know about the LQ engine's until I started reading your build.
