What motor would you choose? To put in a Z car.

The LS2 has iron sleeves, so it can be rebuilt just as easily. The sleeves are removeable also, so it can be resleeved. That makes it more rebuildable than the iron ones.

I checked some prices and the iron blocks are much cheaper. I found LQ4's for under $800. LQ9 was $900 or so and they have better heads. LS2's were over $2k with most over $3k.

Guys seriously. Thanks for the help. I am gonna owe you big time when this thing gets done.

Those price differences are huge and I have a friend with a fat hookup at the J-yards (So i am told) to where the prices for those iron blocks could be almost halved.

Price diff. is what is going to ruin me, so far all the research is saying iron for price and power, but LS2 is like the good go between.

Basically just break it down, the LS2 and iron block are both capable of handling the power and everything is equal except for weight and price. So, is losing 100lbs off the nose of the car worth $2,000?

I voted Iron, because it's really hard to justify 2-3x the price for 100 some pounds. Move the battery to the trunk.

Ask any racer, any real racer, and he'll tell you, it doesn't matter if you win by an inch or a mile... wait.. I mean to say that some people would spend the extra money just to have the lighter engine, but they probably have too much money. Just put some sandbags or an extra battery in back like suggested above, except two, for twice the power.

You could also take a plasma cutter to the firewall and do a "Front Midship" 350z/G35 style. That might put the shifter kind of far back though.

Put in an L24.

Dont know if i mentioned this but the motor would be behind the front axles.

Yeah its tough for me to justify that money for the weight savings and if I had it I would do it.

Not like shit is gonna happen any time soon, I will just keep an eye out for a deal on alum. if not Fe it is.

If I can get into radiology school, I think a grad. present will be a KB or whipple 2.8 or bigger.

You and these root blowers. All motor that thing will be insane.

Why not just get a HUGE cam for it? The most badass roller setup you can bolt on. That's what I'd do. Then just I/H/E like a civic.
