My new LSX engine builder said everything looked fine pistons,bearings. Rings lost seal due to reusing old 100000 plus mile rings from junkyard motor. I'm sure 900 plus flywheel hp didn't help...
Ok gotcha, thanks for the feedback. Cant wait to see how the lsx motor turns out and what HP it makes!
I'm hoping my stock reused rings make it. I'm probably not going to turn mine up that car right away.
It is good to see that it made that much power through the stock short block. Those are killer numbers. Soon more people will get it
I'm from the detroit area and just wondering who plumbed the turbos and what it cost for piping, welding ect.
Diamond Fab in warren mi built the turbo system. Give him a call.
thanks a lot, been looking for a good fabricator..
New LSX block motor dropped in, should have it fired up tomorrow.
I cant wait to see the results with this motor!
Neither can I.
How about some real tech Dave, seriously I'm really interested in hearing about some of the issues you've run into with this swap and the combo. How come you made 450 less HP than Hot Rod and you followed their recipe? Do you think the Hot Rod article was BS or did you run into some snags along the way?
How about the guys on YB.com running bottom 8's with junkyard motors, do you still think this is doable?
In your limited time with the LS motor before it expired how did it compare to the twin 67 turbo Buick V6 you guys ran? It almost made as much HP as your single 70mm turbo 109 Buick V6 did but do you feel it made that kind of power easier and with a safer tune? Do you think if you turned it up to the power level your TSM combo made it would be any different?
Do you think the new LSX block twin 70mm turbo motor will make more power than your twin 67mm turbo Buick V6 used to run?
I am sure you are going to think this is a slam and some kind of witch hunt but its not I am really interested to hear what happened and why you guys came up short. If you don't want to share or discuss that is fine and I will just ignore the personal attacks and BS that is sure to follow if that's the case.
Just got in from a night of cruising Woodward. The new 369 LSX is a beast! A HUGE thanks to Ted A for riding shotgun working the tune up!
any pictures of the new setup?
Please take your stupid questions to another thread. This is a serious thread about a LS conversion. I'm not going to take your bait so don't bother posting here.
Everything looks the same as the old set up just upgraded to a LSX block, eagle crank, rods and pistons. Cubes went from 298 to 369.
Are you using the extra head bolt holes in the lsx block?
Does that block use 1/2" studs? Can stock casting heads be drilled out for the extra holes? I never really looked into this.
The material isn't there with the stock head for the extra head bolt provision, similar to a stock Buick iron head vs ta or champion. The 4 corner head bolts appear to be the same diameter as the arp kit I used for the 4.8 5.3 block,only difference being depth.
Here is a vid of the 369 LSX motor running
I'm in love all over again! LOL Looking forward to see how much power it makes on the Dyno.
Can you notice the extra cubes just driving around?
