Default Falcon's "I am not satisfied with 191whp" build

Sooo... I need more power. Here's the plan. I've been in touch with a local high performance machine shop over the last few days and we've been disucssing possible options. Seems like I've settled on the following.

Bottom end
79.5 8.5:1 Wiesco pistons
Scat Rods
ARP main studs
ACL bearings
Balanced rotating assembly including clutch and front pully
Grind and micropolished crank
Hot tanked block

Head
Fully built FM 1.6L head
Supertech oversized valves
Supertech springs
5 angle valve job
Full port/polish
etc.
Cometic MLS head gasket
ARP Head studs

This block coupled with an upgraded GReddy turbo (19t compressor wheel) and 20+PSI on water should yield excellent results

I already have a full 2.5'' downpipe to 3'' exhaust
ETD Manifold
RX7 460cc injectors (will need to go with some larger injectors, thinking injector dynamics
Dual fed stock fuel rail (will be upgraded to a high capacity rail)
190HP Walbro pump
MS1 Hi-res

Etc. etc.

My goal is a reliable 300whp. I will NOT fall short! Lol...


All this, while my fully built 13B needs to go into the FD and that needs to get back on the road. But I've got no motivation for that right now. I need more Miata power!

Yep. I'm nearly maxed out at 235whp with my 450s. I'm going MINIMUM 620cc.

Whats up with the rods, you find a better deal (wanna share )

If the crank is good leave it alone. Don't remove the nitride treating on your journals or you will end up with a weaker crank.

I have a Walbro HP 225 with 560cc RX injectors and I'm at 80% duty at 290whp (mustang) at 16psi. I'd buy the 949 injectors.

Alec's Automotive on Fraser.

I've been directed to them by a large number of people. Miata exp dosen't matter. An engine is an engine. As long as they know what they're doing and build it to proper specs you should have no problem.

Can a 19T support 300whp? Even with water I figured that was pushing the envelope.

Any chance these guys have successful experience with road-racing engines? Its another world from the 90% of drag racing engines.

I've been to Alec's Automotive (http://www.alecsautomotive.com/) a couple times to get my flanges flattened on their enormous industrial sander. Not the cleanest shop, not as if that means much. They seem like pretty good guys.

I don't see why not looking at the compressor map... it should flow up to 370bhp without choking.

There is a difference. American bhp uses the 5252 value, Canadian 5460. Ask the dyno operator to use American BHP is you want to compare to everyone here...most do anyway.
