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!

With those injectors you will.

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 :D)

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.

:d

Which machine shop you going to use? Are there any with much miata experience?

Good build! I'm shooting for similar goals myself on my next build...

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.

Nah, I'm going to get the rods you PM'd me.

What are they? Cat Power?

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

Canadian or American bhp?

lol... didn't know there was a difference.

Thought bhp was british horse power???

brake horse power. or IIRC otherwise known as flywheel HP.

Sorry I was joking... damn internet.

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.

It was 5252.

Why go full retard on the motor but stick with such a small turbo?

You're going to need to upgrade your transmission at these power levels too.

Is your diff still a 1.6?

The transmission will be just fine. I'll worry about that when it actually goes.

The diff is a 2 way mahura with the mahura ring/pinion in a 1.6 case.

As for the turbo, I have it. And everything associated with making it work including a full exhaust and ETD manifold. It will spool well and it won't choke at my power levels. Sure the intake temps will be hotter, but I'll be running water/meth at high boost so it will be just fine. On the street I won't run it higher than like 10-15PSI without water.

And I like going against the grain.

Funny how everyone is all about ID injectors now.

They seem like a good product. I may also just get some 560's and throw my adjustable regulator from my FD onto the car... (you know, since it's apex seals are broken... lol)

What is your shop quoting you on that engine work?

They are. It's just funny because the last time I brought them up one particular member on this forum told me they were overkill and good luck getting them to idle, and now that same member wants a set. Amazing how fast things change, isn't it?

bhp is base horse power not brake horsepower. brake horsepower is only slightly shy of wheel horse power. bhp is what the engine will make on an engine dyno with no tranny driveshaft or rear end to spin. brake horsepower is what the car would put out on one of those dynos that you take the wheels off and bolt the dyno onto the hubs. wheel horsepower is the only worthwhile way of measuring it, everything else has variables from car to car.

bhp means a lot of things.

nothing like doing stupid shit for the sake of being a god damn moron. Adding water injection isn't going to make the compressor map change enough to magically gain efficiency.
