Build Thread: Lsx, 4L80, GT55-94: Street car WS6
 

Well I picked up this car from MightyMouse in May of last year. Car was a monster but being the power junkie that I am I needed more and my hand was slightly forced LOL

After some issues with the stock crank and ERL block I decided to go LSX block with a dragonslayer crank.

Got the car back on the ground and drove it for a bit. Going to the dyno this week. Numbers will not be posted until after tx2k13 and the next Texas Invitational



Tiago is the man! If he says he is gonna do something he does it and does it well! I am always impressed with his work and he will be the only fabricator I use! He provided hours of advice and days of work! But he enjoyed the work he was doing most of the time! LOL!!

Seafish helped track down parts and supervised the job LOL!

Dopefedz/Bizzatch both come by and helped out when minor issues came up.

Blkcoupe90 did the majority of removal and installation of motor and trans.

MightyMouse: answered any and all questions I may have had, no matter how stupid they may have sounded lol. I owe you big time Dave!


I wont lie I considered putting the project on hold but these guys didn't let me. I am grateful to have such a great group of skilled/talented friends.

I have over 500 pics of the motor build/this entire process. As I go through them I will add more pics.

Looks good, it'll make in the 850 range, lol....

How many cubes did you go with? Crazy to see a crank break like that. Def dropped a coin or two on that setup..should be a monster.

what kind of gains in times are you expecting? or is that top secret too?

Same cubes 364ci...

Car drove great yesterday during break in. Can't wait to see what it does on full power!


If the car goes any faster than it did before I'll be happy if not no big deal. I just wanna drive it and have fun.

Old turbo was maxed out at 1060rwhp this one has much more room to grow if I can get it to hook and hold the power it should go faster but I know it's not gonna happen on just one track outing.

Glad I could help, good to see that puppy back to life.

Very nice build Bryan can't wait to see what it does at tx2k13

Glad to see the beast back in action!

Those all pros are sweet

yea budddyyy

the old setup made 1060? dyno numbers really dont mean shit so i dont blame you I think its more about the track number.

Thanks guys!

1060rwhp unlocked but ran a best of 8.4@162mph

It will make what it makes on 30psi :)

Looks Nice, any particular reason for cathedral ports other than to reuse your intake?

I think the new setup is good for another 300rwhp.. :D

Congrats on getting her done man and great work Tiago and everyone involved.. :)

Already had em, why not use em?

I wanted to keep the combo as similar to what it was before besides the new block/crank and turbo. If they become a restriction I'll consider buying the newest/greatest and latest heads.


LOL fuel system will be the limit right now I believe. May switch to a single Weldon if needed.

Makes sense. I guess I assumed they where new heads and didnt think that you just reused the whole topend. looks good none the less and congrats on getting it back on the road!

billet 94 = :devil: and stock intake manifold = :bomb:

Looks good like good quality fabrication for sure, congratts! My build is almost complete also. LME LSx 427, 4L80, TF 245's, and also a single T-6 turbo.

Thanks! We will have to get all these high Hp local fbodies together one day and just drive around in wife beaters with the t tops off while jamming some kid rock lol.

Lol, we can make that happen, open downpipe all the way!
