60s were great on the street. 100s will be fine.



GOOD tuning plays the biggest part in what size injector is driveable on the street and has good manners.

Good deal I really appreciate all your help and input here buddy. this is a learning curve for me as I've never really experienced a modified turbo truck been a long time coming for me

So I'm in a delimma I'm having a really hard time deciding if I should polish or powder coat my cheetah compressor housing? If I powder coat it I want to go white as close to the gm summit white as I can but my wife says my ocd will kill me if I nick it during installation. My question is polish or powder coat? If I go white how do I minimize the chance of scratch or nicks during install micro fiber towels and masking tape? Or what? Thanks in advance :thumb:

I don’t see it being that hard to get the turbo in there without Nick in the compressor housing. Personally I would go polished. White never looks very good long under the hood due to dirt etc getting imbedded in the color.

Alright so that I'm finally ready to install the 71.5mm cheetah I'm going to the polish the cover and notice the compressor outlet is dented probably not enough to bother most but it's my first turbo and I want it right. What are the best methods to reform cast with a cone and heat or does anyone have a spare lbz compressor housing I could purchase that's in good shape no dents or scratches so I can have it machined and finally enjoy my first aftermarket turbo thanks in advance :thumb:

Got a picture? I doubt you'll have any luck reshaping cast aluminum

Bare with me I'm trying to figure out how to post them here my theory was a stock pot with cooking oil big enough to warm the whole compressor housing up and a tapered brass or soft metal cone and dead blow hammer to swell it back to a symetrical circle like it supposed to be. What's your thoughts

Might want to call Fleece to see if they have the exact housing already polished for the 71.5 , it would take an expert in the field of metallurgy to be sure of the type of heat treating that housing was treated with for strength and vibration ! For a few hundred bucks it might cost way more than that when your turbo turns into a chipper !

Thats probably what I'm going to do. while I'm on the subject of fleece has anyone used the new oil feed they offer. It plugs the cam bearing oil feed and ties into the main oil feed on front side of the block for vgt. it's on there website I've never seen a failed cam bearing cause a lack of lubrication and fail a duramax turbo in stock setup is that more geared toward high rpm high horsepower trucks? Enlighten me please

It dose not happen very often but all that has to happen is for the cam bearing that supplies oil to the turbo to just turn enough to block the oil hole it is all over ! So for piece of mind it is worth it in my opinion if your thinking about going that route ! People with twins and triples use them all the time !

So im bringing this back up I've finally figured out I'm going to polish the comp cover and do the ds intercooler pipe white now my next question is I'm going with Rick d lance tow flow replacement up pipes I'm going to leave the egr riser and blocker plate in place to keep stock appearing under hood. My question is who has the ricks tow flow replacments and how do you like them how did they fit? Smooth install? Also if anyone has insight should I jet hot the turbine housing and dei titanium blanket or just blanket? Mainly want thermometric efficiency. Any insight will be greatly appreciated thanks :thumb:

If the tow flows are anything like PPE's, im assuming they are better, then not a bad install, and definitely reduced egt's a hair. Get one of Levis's turbo blankets. They are very affordable and well made. I have used his in two different scenarios and both times they were excellent with keeping the heat inside the turbo and not in the engine bay. One big thing that keep heat in line as well was wrapping the 2in up pipes and down pipe in a heat wrap. I can open my hood any time and there is very marginal heat coming from the rear of the of the engine bay.

Rick's up-pipes are a great choice. I've run the stock manifolds and his up-pipes on several builds. I believe you get most increase with the up-pipes alone on 90% of the combinations. If I remember there were some engine dyno results posted showing a healthy improvement in HP with just the up-pipes. I've had several turbine housings coated (didn't use JetHot - the turbo shop uses a military type coating used on gun barrels). I would recommend doing either the coating or the blanket. The blankets are very effective but they will not be kind to any type of coating over time.
