what coilpack(im sure thats what it called)should i get when converting to EFI?Ive got a FRST OFAB ECU(if that make sany difference) do i need a FRST or XR3I one?

 

all coilpacks are the same mate - any cvh engine one will do. If ur going efi, i'd go cossie management, not Fiesta.

 

its cost of cossie management that puts people of tho

 

maybe, but if u are building an engine thats a bit special, then u really need it. Beige's only do 220 or so hp, and v few people know how to make it work with bigger.

 

Plus it is possible to get the cossie bits for good money sometimes

 

ignore this....from what ive HEARD from a few major players in the tuning world,is infact the frst ofab gear is very tunable if in the right hands. I was speaking to area six the other day regarding my zetec turbo im building ON OFAB MANAGEMENT, and he told me that on bajoo spec injectors,they've found a way to map ofab up to 2BAR OF BOOST!!!!!!!!!,THATS 29PSI!!!!!!!!!!
the only benefits of cossie management is the options you get with it,eg being able to run anti lag,water injection control etc......
BUT.......................

think of it the way i have.

people try all these uprated aftermarket managements to make their car go faster..........

But if you read up on paul ripleys old frst.

It was a full zetec 16v turbo. standard rods/crank. Low comp pistons, STANDARD head. set of cams (i think) hybrid T3 turbo ON standard exhaust/inlet manifolds. Bajoo spec injectors. 3 bar map sensor, Bajoo live map.ehaust/airfilter. Thats it!!!!!!!!!!
This is a cheap engine spec really compared to what most a paying now days.
NO SILLY t34's or roller bearings etc etc. yet
even today,not alot could touch these times(APART FROM THE ODD MEGA 400-500BHP MONSTERS OUT THERE!!! AND THATS MY POINT!!! How much have they spent.
Its all about getting the RIGHT people to set the thing up.

 

yes, thats all very well, but u are limiting urself from the outset. If the car has OFAx from the start, then sure - use it and tune it. If however u are going to the trouble of a complete change of management, then why not go for the more tuneable option? OFAx is horrendous on fuel economy for a start.
