I have been chasing software bugs all week, basically going from a bare bones Haltech Elite 750 to their fancy R3' Hopefully it starts today

Gosh 240hp would be pretty bad for the amount of time put into my motor:) I guess time will tell

Super cool stuff

I am getting roughly 294.5mm +-.25mm total length from head flange to velocity stack bell. Throttles with the stacks are =153mm Phenolic spacers =10mm Intake = (harder to measure since it isn't straight at all, center of bore to center of bore is 131.5mm Stacks have a max opening of 80mm, they taper down to 50mm at the throttle opening, then 48mm throttle blades, then 45mm at the intake to throttle flange. Then slowly taper to the port size of 37.08

How would you like intake runner length? Total from the stacks to the head? Cam is .525" lift and duration of 240 @ .05 valve lift

Looks like I am 37.08 This is the porting plate used to port match my intake to my head. Each aspect is port matched. Picture is prior to port matching, but shows the bends My porter (Andy) secret sauce is how he does his short bend, but I have no idea exactly how he does it. He seems to think the E31 can flow the best and is the best for "race engines" My car is a street car, so overall my goal is fun drive around and doing canyon driving.

Port work by Andrew Kazanis Dsi valves Diameter: 45/36.5mm Length: 118mm, titanium retainers. Isky springs. Bonk cam. Roughly stock exhaust and intake port sizes. Vapor honed inside and out. 221 CFM flow at .45-.5 lift. Rebello JE Eagle pistons and toyota rods Mine is 88.5x88.5x.25x3.14159x 84.6x6 /1000 = 3122cc My intake is port matched to my head, throttle bodies are tapered bore to my intake, they are 50-48mm (at the butterfly) then 45mm at the DCOE flange.

New Haltech R3 harness is going in! So far I love having the ecu on the battery, it has made the process super easy

Yeah the PAMS have huge ports, the Japanese tuners seem to prefer huge ports. I think my port sizes being roughly stock and flowing as high as they do, so work very well.

I always thought an S2000 would be fun to own

Cool!

Use a liason. I have bought direct from star road through Jesse. Also it's normally cheaper to do it this way. https://jessestreeter.com/

Just contact them directly. Use a liason, they will sell them to you.

Fuse on my 1970 is below the ash tray.

No PAMS head for me. I am pretty proud to own one of Andy Kazanis's heads. I believe he and a few others think the E31 flows the best of any of the heads, with enough effort.
