Jeepers, took my time about it, but the little EA81 4 speeder is back on duty. With nearly 36,000km on its full rebuild with 40 thou oversize slugs, 20/60 solid liftered cam it finally gets a test drive.
Pinch pic from lesser appropriate heading
The USDM EA82 spfi inlet manifold was chosen for its throttle body for best LPG induction with the LPG carby (mixer) sitting directly on top, eliminating petrol carby or my slightly poor choice of another efi throttle body adapted to the EA81 inlet manifold I made up for the initial conversion. Whnen I spied Tweetys spfi manifold - thought BINGO !
Got the added bonus (bragg value only maybe) of the fatter look to the spfi inlet. About 6mm fatter log on the outside, guessing same is inside when compared to EA81/82 carb inlet manifolds.
At a guess, Tweety is gonna be a different kettle of fish to mine as she has a weber on a lighter unit - trike, mated to a 3 speed auto and rear wheel drive.
Mine, being LPG is likely gonna be different to anyone else that does an EA with weber conversion on an spfi manifold.
I have found a doughy spot right between 112kph and 117kph
and it may be my cam choice coming back to bite me again. This is sort of an overtaking speed, but guess I am not gonna be passing someone doing 110 now am I?
Fortunately third gear top speed increased from 110 to 120 after fitting the EA82 Y pipe and cat. I've not found myself in an overtake situation yet to see if 120 is no longer its limit - with the fatter intake.
But, can see Tony smile soon, when he learns how crisp and torquey this thing is down low with slightest squeeze off idle on the throttle in 3rd gear at about 30kph. I am sure this is something new since the
f a t inlet went on
