My Turbo LSX Z31 Builld

With the 4.8 together I needed to find a clutch. I originally ordered clutch but they requested I buy theirflywheel. Which informed that would be useless for me. Well that struck a cord with them. So I explained my setup & they told me the LS wouldn't even fit in car. I told them to Google my car which must be mystical unicorn ROFL. Got my refund and began searching for another option. Found a couple options. In 1 hand there was an affordable 700-800$ clutch. In the other there was a 2100$ clutch that was way more than I needed. The 1st clutch appeared to fit my needs & had a nice price to match. So I gave the clutch maker a call. They informed me that my set up would be pushing to the limits of that clutch. They've had people make 800+hp but on less torque producing V6's. Not wanting to be held back by my clutch I went with option 2. It hurt in the beginning. Hell this clutch cost more than my car, turbo, engine & transmission combined lol. But it'll aid me obtain my goals & pay for itself in the long run. Due to the fact it's a twin disc & can be rebuilt. I went with Ceramic & Rigid Organic disc combination per Clutch Masters recommendation. The clutch comes with acustom flywheel that allows you to back the LSX with a Z32 transmission. With that said they're made to order. I was quoted 3-4 weeks for them to make it. I figured it was likely another week for shipping. Boy was I wrong. My clutch was delivered in just 10 days!

While I was waiting on my clutch I went ahead & had my starter rebuilt.

I ordered some grease fittings for the finishing touch. But I'm still waiting on them to arrive. That way I could grease my steering rack during routine maintenance. I'll add some pics in my next update. 

Sold vs Factory rubber bushing & Installed manual rack with new sold bushing.

To finish up the 4.8 I installed my injectors, fuel rails, intake manifold, billet EGR block off, alternator, billetbelt tensioner, & serpentine belt.I also reworked/wire tucked my gold box harness. I relocated the coil packplugs & coolant temperature sensor plug without any cutting of the harness.My main goal is reaching180+mph in a standing mile. I'd also like to trap 135mph+ in the 1/4. I wouldn't mind seeing if this little 4.8 can make 600whp on E85. It'll still be stock bottom end & stock cylinder heads. I'm not really too concerned with a dyno sheet. I'd be ecstatic if I could reach any of my goals with this little 4.8. I should have another small update within the next couple months. Thanks for stopping by.

Thanks, and that cleared the power steering bits on the rack OK? Will probably use electric power steering on my Z31 which will allow more front space for the sump.

 

By using the Dirty Dingo engine mounts 4th gen Camaro/fbody oil pan clears the rack perfectly. Here's the thread on the Dirty Dingo mounts. http://forums.hybrid...ts-for-the-z31/

 

 

I also attached some clearance pics with the turbo kit off.

Well the time has come for another update on my build. It's a small update but an update none the less. The 1st item on the list was buttoning up my manual rack. By installing new grease fittings, tie rods, & boots.These are grease fitting sizes were used M12x1.0mm, M14x1.5mm, & M16x1.5mm.

Got tired of seeing & smelling the interior of this car so I tore it all out. And yes that is house carpet smh......lol. Check out that 14+ year old unopened 1 liter pepsi. Well it expired over 14 years ago. Found it under the driver side seat. Needless to say it went to the trash immediately. The last 2 pics are of the pile that went to the trash.

Then I drilled a hole into my firewall for my engine wiring harness. The hole I saved during the engine bay work was too far away for the harness to reach. Unfortunately I did the engine bay work before I purchased my ecu & harness.  :(
