Hey. I have a 88 rx7 n/a that needs a engine rebuild. I was just going to keep the rotary but now I like the ls1 swap. But, I have no idea where to start. I need info and a estimated cost. Thanks

PM owen is fat. I think he has his entire spreadsheet handy, which gives an outline for a well done, realistic swap.

The sky is limit with these things though....

Go for it. I am picking up a mustang GT next week for my V8 swap. I am putting it in a first gen though. Go to torquecentral.com they have lots of info.

It's so tempting but it looks like alot of work and I have a feeling it would cost alot to do. Oh well I'll just turbo the engine I have.

You have no idea how easy it actually is. Ls1's are a bit more complicated than the average V8, but they're much simpler than a rotary as far as wiring and vacuum lines. Not to mention double the hp of your N/A and triple the torque - STOCK. I wouldn't try to sell you on an idea you hadn't posted originally. Just my thoughts. My FD is getting an LS1 - I'm in the beginning stages right now, it's my winter project.

a spreadsheet for what?

It's a list of everything he's had to buy including prices for it, if I recall. Quite handy if you're not sure what you need to do the swap. I've got one for my FC/small block swap too, somewhere. A LOT of people ask how much it costs to do this stuff. Repeatedly.

ok simple question. i have a walbro (taking it off and selling it) going to use a mech fuel pump. how do i fix the no puel pump in the gas tank? can i extend the fuel line going into the gas tank?

I don't see why not, all the line does is pick fuel up and you need it to be at the low point. I'd recommend an electric fuel pump though - I have a mechanical pump in my FC (already had it so it was cheapest route) and I would much rather have an electric fuel pump.

no dont do it you can make easy 500 rwhp on a turbo rotorary.why need more v8s just add more weight the only reason to go v8 is that you dont know shiz about rotorary engines

razorback

pay attention, no it doesnt and i know enough about rotaries to know its not easy to make 500hp. i like rotaries too but its MY car.

The Other Engine Conversions Forum is for discussing the technical aspects of engine conversions. If you would like to debate whether or not a rotary-powered car should be converted to run with a piston engine, then please post in the Lounge.

PS: A V8 does not necessarily weigh more, and is easier and less expensive to produce 500rwhp. Just because you do not know "shiz" about a V8 doesn't mean you need to bash people in this forum.

rotary rockett13

Thats alright if you guy want to build an aluminum block v8 and try to get it to the weight of a rotary.Also you can make a easy 500 rwhp out of a turbo rotary.I had mine dynoed at 538hp and 398lbs tq.Ported and single turbo.Also to acheive 50/50 weight ratio you need to set the motor back in to the fire wall.I do know what I am talking about I built a 2 gen.With a ls1 6spd and would love to have the rotary back in it.After what I spent in it.It still runs almost the same.Yes it does have massive torque.But you can not use it.Unless you back halfed the car then I would understand v8 rx7.But the cars are so light you dont need that kind of torque its not a 1970 chevelle that weights 2 ton.I have a 1994 rx7 now.Single turbo and run a 10.68 consistantly.I have seen where a fd3s ran a 10.98 pretty much stock..I was not trying to **** anyone off.But it seems that the guys that are v8ing rx7s are guys that own mustangs and camaros.I think it is more impressive to see a 1.3L 80 Cubic Inch motor SPANK a BIG 5.0L-6.0L V8.Also it cool to even see someone put a 4 cylinder or 6 cylinder making 500-900 hp in a rx7.Still its not as small as 1.3L.But go ahead and screw another rx-7 up like I did at first and I will never make that mistake again.

Wow, lets break this down real quick.

[QUOTE=rotary rockett13]Yes it does have massive torque.But you can not use it. QUOTE]

That has to be the BEST argument ive heard. It about sums up your entire conversation perfectly.

RageRace

Who are you to judge how much torque is enough for this guy or this car? And why WOULDN'T you need it? You do know that if you had more than 398lbs of torque, you would be faster right? And let me get this right, are you saying that an Rx7 cant be fitted with the proper suspension/tire setup to deal with stock ls1 torque? Your beginning to make yourself sound ignorant

RageRace

Did it EVER occur to you that getting the identical weight of the rotary may not be the only reason people want to do a conversion

RageRace

Ive never owned an American car in my life, but, what exactly is the point your trying to get across here? We ALL own RX7s, and have our own personal reasons for wanting to do a conversion, or not. And why would you say something like that if YOU have an V8 rx7?

"I think it is more impressive to see a 1.3L 80 Cubic Inch motor SPANK a BIG 5.0L-6.0L V8.Also it cool to even see someone put a 4 cylinder or 6 cylinder making 500-900 hp in a rx7.Still its not as small as 1.3L.But go ahead and screw another rx-7 up like I did at first and I will never make that mistake again."

Of course it is impressive for a less powerful car to beat a more powerful one, why wouldnt it be. But why would your idea of cool be based on who can go the fastest with the smallest engine. Maybe you should start racing RC cars or something. And again lets get this right-" Also it cool(LOL, I like that) to even see someone put a 4cyl or 6cylinder making 500-900 hp in a rx7." So your saying its cool to put a 900hp 6cyl into an rx7, but its screwing up the car with any type of V8 swap. LOL!!!! You my friend have just got the trophy of the year, Raise your hand and claim your prize.....

where can i find one that will fit my motor (dodge 318)?

rotary rocket 13-Oh here we go again with tales of an "easy" 500 rwhp out of a 13b, I suppose it will be reliable, streetable and run on pump gas as well. Does your car actually run these numbers or are you "internet racing" and estimating what it should run when you install these parts? Got some pics,dyno sheets,time slips to back your claims?

Can't use the torque? I seriously doubt you have even driven an ls1 powered rx7......

This debate is getting old, but sometimes I can't help jumping in.

rotary rockett13

sure here is some pics.I have pics of ported housings,turbo,pics of under hood what do you want.

Was looking more for some proof of a "consistent 10.68" car, not a bunch of parts which may or may not make a 10.68 pass one day.
