Ok i am very new to rx7's and cars in general i guess, well my brothers girlfriends dad is selling a 351 windsor engine for 300 bucks, i am planning on buying this and putting it in my 87 rx7, now, if i do put it in, is there any other suggestions that i would need to change with the engine? Also, when i get the engine in, do any of you have an eta on how much HP i would be having, everything else in the car is stock. Haven't got the money right now to put some mods in it.. Anyways, thanks.

Uh... power? You can get a LOT of power with those damn things, and theyre hardly slouches to start off with. Also, if you know what to get (cams, heads, intakes) you can get some serious muscle without spending a lot.

And yeah, if you want, you can basically take it as far as you want. A 5.8 liter v8 is hardly going to be weak.

 

Also, you will probably get flamed for wanting to put a piston engine in a rx7. Just get past the idiots.

What is it out of, a truck?

I have the same engine in my 92 F-150, 5.8L and 210hp IIRC. Not really worth the swap IMHO, a TII will easily put out that much HP very reliably. The Ford motor is probably all cast iron. I have read that the limits of the block are somewhere around 400hp.

Start with a small block chevy, make sure you get the right motor. If you buy the emissions era motors you'll end up buying new heads, intake, cam, etc, etc. Spend the $$ upfront on the right foundation.

 

stock the 351 blocks can handle 800 horsepower, stock 5.0 can take 600 before they split.

 

I have a grannys cradle to bolt a windsor into the FC chassis with a t5. pm me if oyu are interested. I want $315 for it shipped, OI paid 370 shipped form grannys. Pm me if interested.

 

The truck 351's are the ones to get. They have football rods, and are more "heavy duty".
All you need are to slap a set of heads on it, put in a cam, and you can Easily have a 400whp street beast.

I'm in the process of building a 351 windsor for my '91 coupe.

You're going to need the oil pan from a 351 crown vic, also.

 

pink, which part of arkansas are you from?

wait..or are you greg?

 

but of course, by the time your making those kind of numbers you'd probably want to switch to something which a lot of forum members seem to be foriegn to, an aftermarket block. Dart probably makes the best, followed by FRT.

 

mehhhh to displacement... keep the car weight 50-50 and get a 2.3 turbo and holset hy35w holley 950 commander onboard laptop and volvo 16 v head you'll be hittin 500 rwhp ez. This be my plan.


oh ya and i keep 27 mpg highway under non boost conditions =/.

duhrrr :p



trenyon,
you can keep it 50/50 with a v8 as long as you have an alum. hood, relocate the battery to the back, and get rid of alot of the un-necessary junk up front.

 

LOL and spent 3 times whata healthy SBF would cosat you.

 

If you're lucky. Not to mention the fact that Ford mounts already exist to bolt right in. Fabrication costs more than engine parts.

 

Actually so far i've spent under 1000 dollars for the TOTAL car... and I have the engine, tranny, rear, car, relengthened DS, honda lug patterned axles, turbo and manifolds =/.

all I really need is a CPU, some tires, and a few small electrical stuffs.

I didnt need to spend ridiculous amounts of cash on those granny mounts.

My welder is welding the solid mounts for 30 bucks =/.

you guys are on clack!

 

2.3 turbos are insanely cheap to work on. Holsets are less than $1K (get em from the cummins diesel boys, or a JY, whatever) and you can use a EEC tuner if you dont mind rich idle while you save up for management.

All you REALLY need is FMIC, 40bob manifold, rotated or custom intake (also... 40bob, or a local machine shop to cut/reweld the intake) new rold bolts, all the plumbing and **** done, injectors once you get past a certain power level... and uh a holset if youre going with one, else you might spend more money on a diff turbo. Also, getting a big VAM and TB couldnt exactly hurt either. But, well, all this **** is NOT very expensive! And, a maxed out stock 2.3 is roughly putting down what a SRT-4 does... 230-240 whp with VERY fast spool. More than adequate for a rex while youre piecing together your bigger turbo kit.

Haha ya smoke another one.. The 302 can handle up to 500+ hp all on the tune. The 351w can handle 1000hp so before you say they can't handle 400 do you research
