Budget lm7 s13 build
The first day i picked up the s13
I got a 5.3L LM7 here with ls1 intake manifold and fuel rails from an 06 Tahoe with under 20k miles that i got for dirt cheap. Lets just say i made all my money back selling the extra heads i got with it.
I'm probably going to go with a 4l60e auto for now just to get it running and troubleshoot any particular issues that may arise. T56 is coming in later down the line, along with an AL block most likely to trim off the weight. But that's way in the future once the car has taken shape
The overall concept i have is for a straight track car for time trials, autox duty and general playing around. Right now its stripped, waiting for me to stop being lazy and sand it, seam weld it and cage it
I'll keep you updated if you're interested as it comes along now that it should start warming up
**2/24/11**
Been a while since i updated...been busy with work but have slowly been picking away at this and that. Went ahead and picked up a t56 w/ ls7 cluch/flywheel for a good deal to back it up. There was no way i could forgive myself if i stuck an auto in it at first, lol
cleaned up the engine bay and sprayed the first coat down of primer
Test fit the compression fittings to run -6 line all the way back
Pounded in the pilot bearing...hope i didnt botch it :/....lol
**3/22/11**
finally did a test fit....everything seems good so far
okay so when i tried to turn the engine over by hand, it would turn 90* then stop....i didnt force it, but it def wouldnt turn. I took it apart and heres what i have found
total f'd....the whole combustion chamber has sat for too long, the valves are rusted and the cylinder wall has light rust. The block itself is fine, ill punch it out to 5.7 and just go ahead and drop the bomb on the motor, forged internals, new cam, bearings, the works
the crank seems fine, as does the cam and chain assembly, but imma go with an ls6 timing chain setup and have a coworker of mine build the motor for around $2500 total. He recently did another lsx build that was for FI that made crazy numbers, hes really good. He thinks with a good tune i can hit around 450-500whp range for the price he has in mind.
I thought about getting a new block, like a LQ 6.0L, but they are still kinda pricey if you to rebuild it in the first place. Either way, it'll be way more motor than the car needs
**5/29/11**
just picked these up, 3way adjustable stances....car is getting caged soon and the motor is getting rebuilt to around 450 to 500 hp with cam.
**6/25/12**
Yes its been forever. Bought a house, got engaged, and just been busy. But good news, I sourced this for a steal.
Fully forged internals, stock bore, cam, etc.
Should make about 460rwhp
