POS motors?

Stick a LS motor in one and have some fun. They are realy pricey too.

Sexy body/chassis, Pain in the ass motor.

Agreed on the LS1 swap.

My buddy had one. I think it ran once since he's had it the last 5 years.

Personally, I think they're pieces of shit.

are they really as bad as people say they are?

How much are LS1's running these days?

No, they are your typical overpriced jap car (ie MKIV supra) that alot of people want because they look nice. Actually both cars mentioned are good chassis I hear but still wayyyyy overpriced.

Cheap depending on how complete you want it. A pull out motor with everything will still be in the $2k neighborhood but you can get a longblock cheap and just find all the other little stuff for pretty cheap. I paid $500 for my last LS motor I bought and also $500 for a complete 6.0L iron block motor with 30k on the clock. Dealer pullout with a bad lifter.

yeah i'm discovering this may be more coin than I want to spend on a toy.

I think they're super cool, with a wicked sound to them. However, as you're discovering, they are expensive to keep up with.

Even I will agree with LS1 swap. LQ9's seem to be fairly easy to obtain, and then you can get a plug and play harness from chevy with a drive by wire throttle pedal.

Much less headache in the long run.

I worked on a lot of them at the dealer. I never liked the Wankel engines. Lots of flooding problems and a pita to work on. And the fuel economy sucks.

Doesn't the LQ9 have a cast iron block? For an RX7 I'd put in an LS motor to preserve the weight balance and handling.

Yes. You would save some weight by going with an aluminum block. I think it's 120 lbs roughly.

I offered that up for saving a little coin.

aluminum is lighter, weaker and mor expensive and if a cylinder gets scarred your screwed.

iron is about 120-150lbs more, alot stronger, cheaper and can be machined easily.




Oh and by mosts standards the LQ4/LQ9 iron block is considered an LS motor.

theres a guy with a black rx7 that comes to TAD with a built lsx thats fucking sick.. looks sexy and the sound of a cammed ls motor really finishes it off.. it was running in the 10s.

i agree w/ the LS platform, i see FD's and FC's by the dozens over here daily. everyone has problems w/ those POS rotaries.

Yes. My buddy went through 4 motors in 2 years and now it just sits because he's afraid if he goes into boost it will break again. And his only made around 420 or so rwhp.

I would ONLY do it if you're doing an LS1 swap, but to get a 7 in good shape and the motor in there I would expect to spend at least $20-25K.

I want one too! But it would have to be a v8 swap. Been looking for a nice roller for a while.
