I'm going to have to disagree with this one. I defer to your knowledge though so I'll say that in my experience the stock transmission is better than people give it credit for. IIRC there are people with junkyard trannies in the 400's. It's a stout unit.Kamin wrote:your ka transmission will eat itself to pieces with the torque of a V8. **** they blow up with 300hp SR's.
i look at stoutness a little different than most because of track useredtop91 wrote:

jerryd87 wrote:dont let anyone fool you there the same difference except for the block and possibley the computer chip(which gm is doing away with to cut costs starting with the ls3 in the 08 vett/10camaro) the ls2 is a aluminum block while the truck engine is a iron, truck block can be built to a higher hp range but wieghts more. inside is the same, crank,rods,pistons cam valvetrain double checked and your numbers are right exhaust and computer detune cause the slight loss in tq and major loss in hp truck engine is tune to engage the tq at a lower rpm though, im personally not investing in them. waiting for the ls4(next in the ls/lq linup is going to be a 6.2L dohc engine *drool*)

Hell its to be expected its out of an 02 model. But anyways i have already started to tear it down and take a look around inside. Everything looks ok but i think i am going to rebuild it just to be safe.
I got a couple ?'s, is it a fact that all ls/q engines have aluminum heads? Cause these things are f'n heavy.
2. Can anyone point me to a good rebuild kit for a lq9, ive looked around and cant really find much?
3. How you supposed to get the rods of the crank? Its solid. Yeah it has two bolts but from what i see they aint doin crap. I have read that you have to make a cut but i wasnt very sure on believing that????????
Well thats all for now im sure more will surface but thats it. thanks
sorry but your the one who is a box of misinformation, the ls4 isnt available yet you posted a picture of a vortec a very different engine. vortecs have "D" shaped ports, ls series has "cathedral" shaped, combustion champers on the vortec is heart shaped with ls being figure 8 shaped, the vortec has 1.89 or 1.94 intake valves stock while the ls series is 2.00 or 2.05 stock, the intakes are different design and bolt pattern, vortec is 2 bolt(not sure if they still make 2 bolt) or 4 bolt block, ls series is 6 bolt, different bolt pattern and design for oil pan cylinder heads may be a different bolt pattern but im not 100% so i wont say on that subject they are very different engines the base engine for the ls is a 350 or 5.7L and grows from there up to a 426 or 7.0L stock i believe vortecs may dip into the 4L area but not sure and going up to the 6.0(but different the the ls series by above mentioned differences) 5.3L has always been a vortec and it has been the most mass produced of the vortecs and as far as the "chip" thing go its a different "tune" in the ecm i know theres know "chip" in a gm module we go through at least one a week here at the dealership and if it where false then how come when i take a ls1 camaro and dyno it i get 300hp at the wheels yet when i reflash the ecu with a corvette vin i get 340 at the wheels? and as far as the t5 goes im suggesting and aftermarket trans i would never go with a junkyard trans not sure about your area but in my area they want like 600-700 for em and theres no warrenty it may not even work they seem to think there worth tons since they came out of firebirds camaros and mustangs, you can get an aftermarket one good to 500hp for about 1200 it may not be as bulletproof as the t56 but its also only half the price brand new my step dads got a t5 in his 89 mustang pushing 350HP and he beats the crap out of it and its fine(thats 350 at the wheels). i dont appreciate you insulting me when im trying to share information especially since the only experience you seem to have is from books and the internet and i deal with these engines everydayZ28ricer wrote:Wow, what a box of misinformation this guy is, please anyone reading this post, just begin disreguarding anything he says..
The 6.0 was available as engine codes LQ4 and LQ9.
Highly recommend the T5 ? Are you kidding me ? The T5 is well known to be a fragile box of gears, probably no better than the stock trans behind any KA or SR, not to mention the T5 never rolled off the production line behind an LT1 equipped vehicle.

Though it has the same displacement as the Vortec 5300 LH6, it differs in that it has an aluminum block rather than an iron one and it uses the same cylinder head as the Generation III LS6 engine.
A version of this engine is adapted for transverse front-wheel drive application. In order to fit into the smaller engine compartments designed for V-6s, the LS4 engine block had to be shortened by one inch. Displacement on Demand is also used. Output of this version is 303 hp (226 kW) and 323 ft·lbf (438 N·m).

Thank you, please dont come again, but please do learn your RPO's
And T5's are weak because of the case, rebuild or buy it new all you want, its still going to be weaker.
Oh and please learn the difference between a Gen 1 based vortec engine and all the Gen 3/4 based engines currently used in the truck, maybe since you work on these things all day you can get some spare time to open up a vortec 4800, 5300, or 6000 and observe the 6 bolt mains since you say all vortecs are 2 bolt main. Another little tip for you the LS1 is 346 ci if you really want to get technical.
