The before & after transformation of the original 2.8L. It went from peaking 121whp @4900rpm and 152wtq @3600rpm to 166whp @6000rpms and 167wtq @4900rpms with the TR1 intake. With the TR2 It picked up another 7whp. All this with a modified upper plenum to increase plenum volume significantly, a TPI twin 48mm TB, set of CNC heads with stock valves, custom headers and custom Y pipe with 2.5” diameter pipes at each bank meeting at a 3” in diameter pipe measuring 3 feet in length. The short block was bored .040 and stock off the shelf pistons and rings. Stock crank and rods were kept. And to bring all that together a 230/230, .512/.512 lift cam with a healthy dosis of overlap was made to use the exhaust energy to pull in the intake charge at the top end to get that VTEC effect. Enjoy!

Same principle that makes airplanes fly is applied to this design. General believe is that the incoming air will ignore the bend and the #1 cylinder and smash against the back wall creating havoc inside the plenum.

After breaking on the engine I drove it to the garage it belongs!

Test drive to break in the rings.

Took this time to data log and do some adjustments.

eBay/aluminum non ported heads 2.02/1.8 Edelbrock Performer intake. Scat 5.7” rods stroker kit. Summit 1106 Classic Camshaft hydraulic. Long tube headers.

Do you think pushrods only connects the lifters to the rockers? Can take advantage of this little stick to enhance all valve timing events?

The current engine in the car now. Low to mid RPM tuning is done. High RPM tuning is next before the shakedowns at the tracks this year.

This is my 3.4L iron headed Fiero driving to the dyno. No music; just sound for the ears of the real car enthusiasts! Enjoy.

This video reveals the adverse effects of piston pin offset or piston reversing or flipping from stock location by the factory. I wanted to find out why reversing or flipping the piston made power and what I discovered based on calculations from a university research paper reassured my assumptions. Get ready because its NOT what everyone believes!
