^ I wouldnt ruin a perfectly good car... i would buy one thats already ruined..

 

waste the time of selling a blown one, when you can swap it and get double money. Tito the world will continue to go on with swaped v8 rx7's. If you dont like it than thats ok. for some of us we do like. I happen to love it. I went to sunshine wendsday and watched the 10,00 rpm starlets and datsuns run and yes when they actually make a complete pass all the way down the track, they are impressive. But they usally dont make a full pass or even to at that matter. Again I do love them so yes there are people who like rotarys and v8's.Tito you are actually lucky that your car isnt turbo or you would see how many miles you get. They aernt cheap.

 

If your car is full of rotary-induced problems, being the primary cause of wanting an LS1 7, then I wouldn't call it a perfectly good car. I'd say it's ruined already. There is an abnormally high number of V8 FDs on v8rx7forum for sale right now, though. See if anyone wants a trade + cash!

 

amen to that. but none the less they are unique and fun to drive. i wouldnt throw out the v8 idea either. a v8 fd is also unique but they have there fair share of problems as well. it isnt a simple plug and play process as some would like you to believe. its long and costly, but the outcome can be quite impressive. ive known people that have done the swap and it can be time consuming and again costly. if you got the hook up on a lot of parts then it might not be as expensive as it could be, but still very expensive. lsX motors arent cheap, then you need the new subframe, all the wiring, fuel, custom this custom that and for what 350hp/tq?

either is a good way if you ask me but one is easier then another. go lsX and spend lots of time and money but could easily make that back and then some. go rotary and its a direct swap plus a quick and easy profit.

no body can make this decision but you. either way, FDs rule the school good luck

 

+ 1

Rebuild the rotary unless both housings/ rotors are trash. (unfortunately you can only know that wen you tear down the motor) Do a compression test, if its got good compression on at least one rotor, chances are you're looking at replacing 1 housing/ rotor @ the worst.

If they're both trashed, then and only then consider a swap. But like Initial FD said, LSX's aren't cheap either, and when people are making damn near 400hp on stock twins (13b), it doesn't really seem worth all the trouble. A built LSX is another story, but then we're comparing apples to oranges. Plus if you've got that kind of money, swap in a 20b.

 

now we're talking

 

When you start comparing 20B to LS1, the LS1 is going to be a much lighter motor, being all aluminum. The LS1 swap can be quite cheap if you consider how much you're selling, especially if your rotary is still in good, or at least rebuildable shape, and you've got a handful of aftermarket parts on it.

If you go the lazy route, you're going to spend about 5K on the swap kit. This includes all the mounting equipment/driveshaft, of course, as well as the custom-fit cooling system, intake pipe, the wiring harness modifications done for you (w/ tuned ECU if you send yours in), the fuel system (minus lines and fittings), and the custom headers that will fit the mounting kit. These are based on Hinson's prices, which are announced to be dropping shortly.

As for the big hardware, the cheapest I've heard of obtaining an LS1 is $2100. That's including it already mounted to the tranny, with the ECU/wiring attached, too. Average prices seem to be around $3500-$4000, depending on where you find them, but again, this includes the tranny/ECU/accessories. Its' definitely a lot of work, but I'm looking forward to it myself. Mainly for the opportunity to be able to clean up my engine bay and thoroughly go through and clean/organize my engine bay.
I'd say it's a good idea whether your engine is running, going out, or totally shot.

 

is absolutly correct Troux. Glad another person here know's what they are talking abvout. Hey btw Hinsons kit is in a price war with dyotest's kit and hinsons kit is know only 1200. Great deal for everything. Do you plan on doing a rx7-ls1 swap?

 

Still kinda debating between LS2 and LS1, but definitely wanna get going on it ASAP. There are certainly interesting things brewing amongst the kitmakers.

 

ls7 FTW!!!
