Want to put a FS-DE engine into an MX5 (Miata). I have a couple of options, one is a B18 manifold which has its own issues (port spacing), custom manifold like yours or ITBs.
Nah just when you rotate a FS 90 degrees so the tranny is at the back, the throttle body faces the firewall.
Should be good.
I'd rather have a 2 or 2.1 litre BP-4W as well but I have this engine sitting around so why not use it:
Custom Weisco ~12:1 Pistons with 21mm wristpin.
3SGTE Rods
3SGTE Oversized Bearings
Modified Crank to Suit Bearings (i.e. tighter tolerances all round) + Achieve thicker bearings.
Modified Head - 5 Angle Valve Job, Blending, Ported and Knife-Edged Intake Ports, Ported and Knife-Edged Exhaust Ports.
Twiggy Cams
Adaptronic e440D
DocB Racing Oil Pump
Peterson Pressure Release Valve
Modified MBSP for Oil Return
Oil Filter Relocation Kit:
- Works Engineering Oil Adapters
- Aeroflow AN10 Fittings All Round
- Aeroflow Black Tubing
Focus Adjustable Cam Gears
MSP Oil Cooler
Stant Low Temperature Thermostat
RR Racing UDP
Fidanza Flywheel - 7.5lb
Custom NPC 760kg Clutch
So far 175whp. Flat lines at 6800 rpm. With the addition of a better intake and a custom header (which is required unfortunatley) and shitload lighter rims. I'm hoping to get about 185-190whp.
Not sure what it will make on E85 but ill throw that at it too in the hope of cracking 200whp
BPs stock can spin to about 7800 rpm, same as a FP.
FS start dieing around 7400 rpm stock. Longer rods mean that I'm willing to rev it out to 7800 rpm. By no means will it out rev a heavily modifed BP which can spin to around 9k in race spec. Or 8200 comfortably on a good street build.
But the extra stroke gives me a great torque curve, the light weight engine gear, UDP and Flywheel make the thing spin up crazy and its just super linear.
Yep.
Havent ruled it out. But its all dollars and unfortunatley it all has to come from overseas (parts that is), and with the AUD parts have gotten about 30% more expensive in a matter of months. That 1600 dollar ITB system you'd been saving for is now just shy of 2100 dollars.
That plus the requirement of a custom header
(Was going to use a BP item slightly modifed to fit).Me or iracemine?
We actually make fairly similiar power. Would be interesting to plot the curves against each other
Yeah. The wallet feels it as well.
Unsure how but the SP20 build really didnt cost that much. Granted i had some good parts to begin with, but thats just prudent buying.
The miata build is going to sting a little.
