Default another RX7 V8 swap :)

OK i am not sure if it should go here or conversions. only because it says hybird "ls1's in non ls1 cars" so here is my story!
I own an 87 turbo 2 rx7, i rebuilt the 13b and it cost me almost 4000 to do it! it lasted me 21xxx miles!




so i said forget the 13b and i went with a v8! since i couldn't afford an LS1 so i went with an LT1. i bought it for 300 bucks knowing it needed a rebuild!

i don't have pics of the heads from before but they where nasty! and i know everyone is like ill but i needed to paint them after i cleaned them
rebuilt with new valve stem seals and valves and locks. the blue is the only color i had left so leave me alone on that! besides one day i will get some nice alum heads


finally started putting her together


next was the intake manifold! yuck it was painted some nasty *** blue so i tried cleaning it but i gave up and took it to get tanked and coated

and finally got it all together!




it was a stuggle getting the motor in being that i had very little help and everyone telling me it can't be done no way and all that crap! i almost gave up

but i pressed on and on and i finally got it in!





now i got most of the wiring done and the pcm programmed! i will have pics of that later and once i figure out how to get the starter wired up to the ign. i will be a happy man!

ummmmmmmmmm those dont look like lt1 heads to me. lt1 heads have D-shaped exhaust ports and are reverse flow coolant. so while this thing may run for a little bit if they are in fact not lt1 heads youll have some problems with it.

hmm interesting the heads where on the block when they came out the car. again this is a caprice motor with iron heads so i don't know if they look different then the alum heads! one day i will get alum. heads just want to get this set up fired up!

I'd get the starter for F-Bodys or Vettes too, if it's running the F-Body compression 10.5:1 (or more since you rebuilt). It's the factory 'mini-torque'. They're awesome starters, even for non-LT1 350s. I used one in my Suburban and my 91 Firebird.

This swap is really starting to grow on me for some reason. I'm not the biggest fan of that bodystyle though.

i feel you. i love the style just because it was cheap and it has a lot to offer. lsd rear end. all the things you need power windows power mirrors sunroof and all that good stuff! but i am a fan of the body style. i would get another if i had the room for it!
