Budget T-trim build help, please.
I have some questions about my build that I plan on starting this summer. I have a 94 Z-28 with a 12-bolt, a street twin, and a stock motor plus bolt-ons. I have been going to build a all forged short block with heads\cam for years now. Every time I start to get a little saved up, I end up needing it for something else and my build money goes back to zero.
I have a T-trim but know better than to try it on a stock motor. How long could I get away with a stock long block with dished forged pistons and a blower cam? I would use new ARP bolts in the rods, mains, heads. How many stock cranks and rods have been broken at the power level I would be at? What kind of power might it make?
At this point it feels like doing this will at least get the blower on the car and let me enjoy it. My big fantasy build seems to be just that. I would probably try to run this setup on the stock PCM with a good in-tank pump setup and a dyno tune with bigger injectors and a msd btm. I really won't beat on the car. I'm sure it will see the dragstrip a few times a year, but it will mainly be a cruiser for me and the wife and kids.
Am I just looking for trouble?

Well considering when boosting a completely stock short block I have noticed that its usually the piston that fails first. If you put a good forged piston on it with Arp hardware throughout the engine and a really good tune there is no reason you couldn't put some boost threw it. Make sure that you don't get greedy with the boost, read the spark plugs, watch your wideband, dont lean it out, and run a spot on tune. there is no reason it wont last a while.
IIRC you have to have the rods and mains worked on to run the arp rod and main bolts. an align hone and r&r the rods.94' Z28 A4 black: turbo build in progress

Pistons are a must. Rods would be the next weak link. Then the crank. A good built 355 stock rods and crank would be a solid setup for what you would be doing with the car.

good pistons, tune, balance/machine work, valvetrain, and I don't see why it won't live for quite some time as long as the rpms, fuel, and boost are matched to the components.

Machine work is expensive and by the time you're done you'll wish you put better parts in it for not that much more $.
ARP hardware in the mains = line hone ($200)
New pistons of different weight = balance job ($200+)
Only way you could really do it on the cheap would be stock crank, rods (resized w/ARP bolts), and dished forged pistons (equal weight as stock, look at Speed Pro/TRW). Keep the RPMs down with a smaller cam, bearing clearances wide, and wider ring gaps and it will live a long time (assuming you can find someone to tune it right).96Z M6, ERE-383 #60, AFR 210s, LE cam, 9", Procharger D1, ???whp

Its all about a proper tune. The donor car that i got my blower set up off of was a low 12 second stock lt1 with a p1sc on it. It was a healthy running car.... now it would push the dip stick out anytime the car was beat on and may have been working its way towards its demise... but it was stock with low boost. Now..... with that being said...unless this is a toy car and not something u rely on to dd... i would not even think about it....

No not my dd. Honestly, it hasn't moved for a number of small to very large reasons in about 7 years.
