RX7 race car project

[PDenbigh]

Someone should get on this. It comes with a roll cage and right now is less than $900. Maybe work a deal for one of the parts cars.

Found on NASAForums if you need more info from the guy.

Will a SBC 350 fit in that?

Will a SBC 350 fit in that?

yes.

[HAULN-SS]

Hrmm. another GRM candidate! I have a 350 that probably needs to be tore down and put back together - but as far as I know the block is good. We could dremel the heads (be good enough for a GRM car right?) - so for the cost of a cam, rings, maybe pistons, and rebuilding the carb, gasket, valve stem seals, and pushrods/rockers, junkyard transmission, and driveshaft...hrmmmm

Something like that would make for a fun project.

I have a feeling it will end up being much more than that though.

I'm bored at work, i'll price some stuff out. bbs

try google, many people do what you're looking to do.

FEM-MHP126-000 $259.95 - Standard Bore, Standard main 350 Rebuild kit on summit, this includes new flat-top pistons, rings, rod bearings, main bearings, cam bearings, gaskets, high volume oil pump, freeze plugs, plastigage, assembly lube.

We can get this in a 30 over size too, if we could score some cheap/free machining.

There's a cheaper kit, no pistons, cam bearings, and a few other things - depending on how it looked after tearing down, might could go that route, it's 139$ or something.

the cam-shafts, if we went with summit, we could get a kit with the lifters for as cheap as 70$, or 170$ for a lunati voodoo cam/lifter kit. I am not sure what heads are on it, so I'd have to do some research to see about the max lift, but these cams are usually in the .460/.500 lift range with stock rockers.

Summit Steel Roller Tip Rocker Arms - 89$

Summit True Roller Timing Sets - 31$

not sure what shape the heads are in, might have to buy a rebuild kit for those as well, I can't find out exactly what the heads are without checking the casting numbers - but i'd guess maybe 150$ - 170$ for that? Kits include:

* Valve springs
* Steel retainers
* Valve locks
* Guideplates
* Rocker arm studs
* Valve seals

Not sure what the carb is, i think its an edelbrock, but could be wrong. Anyway, the rebuild kit on that is $36.95 for a performer series carb. I'm not even 100% sure it even needs a rebuild.

Cheapest I could find on a 3Spd Auto Transmission from Summit was like 645$ - So, this is kind of an unknown, because A) I'm sure we can find A transmission in a junkyard, in an unknown state of dis-repair, or buy a rebuild kit which is why I picked a 3spd...cheaper, and easier to rebuild if we went that way.

Further Unknowns: Connecting the transmission to a driveshaft, to a rearend..how do people do this? Buy special yokes? Swap in a GM rearend?..or is that pretty standard across the board? Also - fabricating, or getting made a driveshaft..no idea the costs on that..anyone?

[HAULN-SS]

Oh yeah - torque converter..i'm assuming would come from a Junkyard car too. If I've forgotten anything, feel free to throw it up. But, yeah - that's getting pretty tight on the budget as is, for that expensive of a roller to start with.

[ViPER1313]

Other things it would need:

-fuel tank
-fuel pump
-wiring harness
-all engine accessories
-radiator
-tires
-brakes

etc, etc, etc.

[HAULN-SS]

Looks like it has tires, probably brakes, and radiator..good enough for pissing around a weekend at a track. Fuel tank, alternator, and PSteering pump, fuel pump all come off a junkyard car, no wiring harness needed, nothing is computer controlled...but shifter/linkage is something I forgot

[CaptainHenreh]

You'd be way over budget. 800 dollars is alot to spend on a roller for the Challenge. Recouping budget is a big part of the Challenge...that's about the only way you can spend big money on a starter and get away with it.

You're also forgetting that even if we get cheap/free machining cost...we have to count the typical retail cost of that machining in the budget.

Plus, there are way cheaper RX-7's out there, but I think a Chevy is the way to go. Two years running the winner has been a Ford powered FC, I think the Chevy has greater power potential.
