LQ4 is the "low" compression 6.0. LQ9 is the high comp 6.0. LM7 and later the LY5 is the 5.3.

Re: ls turbo build
 

The 5.3 is.... a 323 in terms of CI if I'm correct but called a 325/327, the 5.7 is 347 and the 6.0 is 364 CI the 6.0 having the 4.00in bore is nice because they have really nice stock heads like the l92 head swap. As far as lq4/9s are only 6.0s and the lq9 if I'm correct has slightly thicker connecting rods and obviously pistons as well check my sig for the ls primer link it tells everything and one last thing I think the gen IV engines started in... 06? Using different rectangular port heads instead of cathedral which means not interchangeable and vvt and few other things making those heads cost possible a little more along with cam although vvt can be eliminated although some of this is already mentioned, TSP 427 6.0 stroker kit would be nice also :-p

Just picked up a 5.3 out of a 2003 tahoe complete minus alternator and ps pump and starter.... Tore it down today, and ready for the machine shop... might change heads, but not sure yet, they are the 706 heads... I gave $450for this engine with computer and all harnesses... Also picked up my built turbo 400 a couple days ago.... Radiator and hydraboost will be here monday!!!!!!!!!!!!!!!

Re: ls turbo build
 

will do.... i'm getting it tomorrow, i'll take pictures of it also.... I plan on ordering new brake line just to run from the mastercylinder to the 1st place they connect just to make it look alot better than what i have.... i think summit racing has a role of tubing with a bender for $80....

Re: ls turbo build
 

my hydraboost came in today.... just ordered my turbo... it's a borgwarner s475:metal:

Re: ls turbo build
 

nice!...those mounts are sick, and the turbo....

Re: ls turbo build
 

i also used dirty dingo ls mounts but different ones i like them except for the welds they kind of ticked me off but still good mounts

Re: ls turbo build
 

I have the pol lower tubular frame mounts.

Re: ls turbo build
 

That turbo doesn't make any boost sitting on your floor....get it in there damnit!

Re: ls turbo build
 

lol..... I just received everything to build the engine. I'm in the process of getting it ready for the machine shop....

Re: ls turbo build
 

Finally got the engine back from the machine shop. Also had a bracket, dirty dingo motor mounts and the exhaust manifold covers powercoated... Still have alot to do... This is going to take longer than i thought :)

Re: ls turbo build
 

everything looks great....but that pan seems a little deep. Mine is too deep and I don't think it hangs down as far as yours. are you sure you have room for it?

Re: ls turbo build
 

Not sure.... Guess i will find out... What pan did you end up going with?

Re: ls turbo build
 

the stock LY6 pan.

Re: ls turbo build
 

I swapped my pan to the stock camaro one that is what I would recommend.

Re: ls turbo build
 

I have the deep pan like you have, and it is almost the lowest point on my truck. My exhaust is about 1/2" lower. And with as much static drop as I have...I should be worried, but strangely I'm not. Time will tell.

Re: ls turbo build
 

I used an 07 Cadillac CTsV pan on my 69 Burb.

Re: ls turbo build
 

Nice!!! Jakes Performance built me a nice 4L80 for my 66 Chevelle, complete with transbrake and 3500 convertor. www.jakesperformance.com

Re: ls turbo build
 

Subscribed. My 6.0 came in yesterday so I will be watching to see the best way to boost a C10.

Re: ls turbo build
 

I was going to have a 4l80 built, but i couldn't bring myself to spending close to 4k for a trans to handle what i'm doing... I would have to drive it for a long time to save enough in fuel to have it pay for itself... I would love to have one tho!!!

Re: ls turbo build
 

Keep me posted on your ideas!!

I thought that i could do this for around 8to10k, but i'm not taking any shortcuts.... I'm looking around 17k for this conversion with painted firewall, holley efi, etc.etc... So, it's going to take me a year or longer to finish.... Need to get my wife to work more :lol:

Re: ls turbo build
 

Just received my freakshow converter, hughes flywheel with spacer and bolts, energy suspension motor mounts and trans mount. I should have it all bolted up together this weekend and stabbed in the truck.. I'll also have the driveshaft and lokar shifter installed and the hydraboost brakes done.... Then i'm ordering the holley dominator efi complete system, and the edelbrock proflo intake and injectors, rails etc.etc..... I'm getting excited:metal: Going to try to get this done before our new baby gets here in may....

Re: ls turbo build
 

How's the install coming?
Posted via Mobile Device

Re: ls turbo build
 

Jegs sent the wrong flexplate.... I have to use the crank spacer (555-601010) and a FLAT tci flexplate (399753). They told me that the hughes flexplate (512-hp4004x) will work... But it's dished and won't allow the converter to pull up enough to bolt up to the flexplate... So if you install the spacer first then the TCI flexplate it will work....

Re: ls turbo build
 

Bummer. Hopefully they will get you the correct parts soon and you can finish the install.

Re: ls turbo build
 

Great progress thus far brother. Got the motor in but ran into a snag with the turbo fitment. As usual I will be keeping a close eye on yours.
