Budget build suggestions I’m looking to do a budget turbo build on 98 z28. For the short term looking to use the stock ls1 short block that’s in the car then do 317 heads with new valve springs and push rods. Then I was looking at the on3 turbos. The 7875 looks very attractive do to the price.
Not looking to make huge power but something in the 500/600 range to the tire.
I am also building another engine for boost but would like to have some fun first.
What advise you all have?

Its been done. Its all been done. Search around. There are probably 500 topics like this one so far this year, almost all were answered.
There are probably 200+ builds here using the 7875. Another 200+ stock LS1 shortblock turbo builds.

Keep it sinple and don’t try to reinvent the wheel. I have a 4.8L with a “stage 2 turbo cam” and a 7875, which is a very common combo. I was able to use a base tune I downloaded from the Sloppy Mechanics wiki page and it fired up on the first try.

317s strapped to an ls1 here.
Build big right off the bat. I regret going t4 rather than t6 initially, and I regret not just doing the complete fuel system from the beginning. Good luck with it all!

For the camaro I really don’t want to cut it up. I’m going to relocate the battery to the back to make room for the turbo and probably stand the radiator up under the core support. Use a different radiator so I don’t have to cut it. I have a lq4 sitting around that I will build for the camaro in the future. But I want to have some fun in the meantime on the Stocker. To be honest I don’t even want to tear it down to gap the rings. It has 160xxx on it so I figure it’s already loose enough for boost😎. People throw a lot of NO2 at LS’s without gaping the rings so I think I’ll be okay doing low boost without doing it. If not then I’ll bore it or re sleeve it, if the lq4 isn’t ready and start over no harm done . I bought the car for $3500 back in 09’. Put a stall, LT’s, built the 4l60e and tuned myself with HPT went 12.57@107 on stock 10 spokes with MT radials with a 1.76 60’

Build the cooling system, fuel system and the boost control system for 1000hp. It will make your life easier since it is so easy to turn boost up. 600 hp limit will last a very short time if you have the same hot rodder addiction i suffer from.
I’m building another engine at the same time for boost. But I have a 67’ mustang coupe that it will be going in. Will be going all out on it.

If you are on a budget then sell the ls1 and 4l60 then put a real trans in with a 5.3. Ls1 blocks are the weakest of all ls motors and typically do not hold up well with boost.
Should be able to sell what you've got for about the same price you could buy a good 5.3 and 4l80.

I did build it myself. It’s built well and will withstand my goal. Now I’m not saying in the future it will be up to the task but for now it should be fine for my power goals.
