The Ford Motor Company introduced their single overhead cam (SOHC) engine in 1970, and since then they have been installing it in close on a million vehicles a year. This means that by now there are a lot of these engines around. In Europe, this engine fulfills a number of duties ranging from everyday workhorse requirements to the higher performance needs of Ford's more sporting vehicles like the RS Escort.

Most likely because this post is in the SOHC KA-T forum. Haven't looked just now but I'm assuming the same type of thread is in the DOHC KA-T forum too.

:edit: That would actually be in the KA-T Basic forum.

They wont work, you need top feed injectors.

Yeah, you just have to get smaller o-rings.

AFAIK you just wire a resistor inline on each injector harness... So pretty darn easy.

for the 230-240 mark, with a stock t25, and 450cc injectors, an intercooler, is greddy emanage and apexi safc really necessary?

You will need something to control fuel. You will at least need an SAFC and some timing retard. I have the same turbo but i haven't put it all together yet. You should ask this question in the KA-T basic section. But like i said you definitely need something to control fuel and the tuned ecu is a big plus, for any large type of hp you need to have a tuned ecu.

i don't have ANY computers other than the STOCK computer and i'm running a T3/T04E turbo with 550cc injectors.
so im looking at adding a turbo to the ka-e im swapping into my 87 hb 4x4. ive got a t25 from an eclipse. im not looking to do anything over 6-8 lbs as this is going to be a daily driven truck. can i keep the stock ka ECM with bigger injectors? and on the list of parts, is the apexi safc2 and the greddy emanage 100% needed? im doing this build on a budget, but if i absolutely have to have this, then im ok with it.

Boost level does not mean anything. LBs/min is the accurate way but most people won't understand this. 10psi with a T2 is different than 10psi with a T4.
