Hey guys debating between the 7670 and 8374 I'm also wondering what supporting mods will be needed for my build.???

 

This is the new member tech section. I'm not a tuner and prefer the stock sequentials, but you may get some helpful info in the stickys here Single Turbo RX-7's - RX7Club.com . And when you're done, I think you have enough posts you could ask for more specifics.

 

Ecu, turbo, wastegate, exhaust manifold, dp, fuel pump, injectors, fuel rails, fuel pressure regulator (the last two really depend on your power goals. A.I. though not an absolute necessity it is definitely a good idea.

If you don't already have it: bolts ons both the intake and exhaust side.

 

Go 8374.

 

8374 is what's upppp! We offer full EFR kits to take care of the entire hot side.

You'll still need injectors, standalone (power fc is a good choice), intercooler setup, ect. Hit us up for info.

 

Also quite a lot if little things you wil need... Various sizes and types of hose , fittings, clamps , turbo oil feed / drain , emissions block off plates, (imo) map sensor that can read to a higher pressure level , battery relocation to somewhere, relay for fuel pump , various gauges of wire , fuses & fuse holders , ideally aftermarket radiator... I'm sure there's lots of little things I'm forgetting... Pod filter of some sort...

 

This article might help you when selecting between the two;

The rest depends on how much boost pressure, and fuel type used. We sell full drop in fuel systems with proven results etc.

 

Alot of money
