Would it be cheaper to buy a complete ls1.

Or grab a lq9 from an escalade. And buy a ls1 intake , injectors, tb , harness and accessories?

The engine will be mated to a t56 and swaped into an is300 with 400whp goal and to tq in the whole power band for a nice summer cruiser.

I'm pretty new to ls swaps.hi

 

Whatever you do, stay away from the ls1 intake. Get an ls6 intake at least, fast intake if funds allow.

 

Yes . I do want to get it running on the cheap. Ls1 vs ls6 . Huge pice difference. I'd like to go h/c/i . Start with a stock heads and ls1 intake and then get a Texas speed combo with a fast intake.

 

Are you looking good to by a complete shortblock or what exactly?

 

There's a reason there is a price difference. You will struggle to make your power goal with ls1 intake. Lot's of people make 400 cam only with the ls6 intake.

 

I just need the opinions from people with experience
This my first lsx build. The way I see it is that I have 2 options.

But a complete ls1 dropout complete with everything.

Or option 2 . Go to the junkyard and get a lq9 from an escalade. I would the need the ls1 accessories, harness computer and intake setup. Also looks like I would need a harness extension.

Which option would be cheaper. And if the lq9 option is more expensive. Would it be worth it to pick up the diaplacement. Sorry for the confusion.

Basically ls1 dropout or lq9 build from the ground up?

 

I went from a LS1 to a LQ9 and definitely noticed the increased torque. If price is equal I'd go with the 6.0

 

Just depends on prices in your area and if you are willing to wait for a deal to pop up. I see lq4/9 motors every now and then for around 5-600 bucks around here. Most complete ls1 i see are usually at least 2500+, without the ecu and harness. Not sure what it would cost to buy all the accesories.

 

Thank you guys. Can anybody tell me a healthy number for a compression test. Close to 180? With a variance of 10. And it says here a vin check is the only way to tell a lq9 vs a lq4
