I really dont feel like switching to MPFI but I was wondering if there would be any inexpensive upgrades I could do to tune up and enhance my motor?
I already got extractors fitted and a K&N air filter.
MPFI is the single most effective mod, and one of the cheapest...
I've converted mine and while the car still isn't a rocket, the difference from CFI to MPFI is absolutely phenomenal.
Rosewood EAII Fairmont 02/90. MPFI 3.9L (formerly CFI), 4spd BTR Auto. Skyline geared 3.45g open center 28 spline 4 pinion differential & axles. 2 1/2" Cat Back Exhaust. King Super Low Springs. Sound: Equalization and amplification by Clarion; Head unit by Sony, Front, Rears and Sub by Pioneer. Planned mods - t5, Extractors, Painting Grey Strips and new front and rear bar.
Look at it this way, EAXR6 had a worked CFI EA that pulled 115rwkw. Pretty impressive for a CFI, had a very lumpy cam, headwork, extractors + zorst, chiptorque chip, etc etc. Now a stock MPFI EA will pull around the 95-100rwkw mark, which means that it only gained 15-20rwkw from all these mods. He then switched to MPFI and is now make 150rkw+ simply from the conversion.
I am curious (and questioning as always!)... how much does it cost approx to convert? What is involved? Is it a mechanic's job? Where do I source parts from?
ATM my EA is going through a crap idle stage, don't know what the issue is. Just had a thought (DOH!) I should check if it idles lumpier on lpg or petrol. If it is smooth on petrol, it's an LPG issue. If it idles crap on both then there's something else.
