Mk3 1.6 engines

[mrcooke]

Hi i'm new here,

I was just wondering if anyone could help me out, i've done some research and seen that with the 1.6 the ABU, AEA & AEA have 74bhp and the AEK & AFT have 99bhp. I know they have slightly different displacement and compression but it seems the main difference between the 99bhp & 74bhp engines is muli-point injection.
Would it be possible to replace the single-point system with a multi-point one on a 74bhp engine? And if so would it help in getting near to the 99bhp figure?

Any help would be greatly appreciated.

Cheers

The AEE  were done on single point and multi point, they are short block engines (tilts forwards)  These were the same as the polo 1.0 1.3 and 1.4. 

The AFT is a tall block (like the 1.8 and 2.0 gti engine) tilts backwards,  these were all multi point, i dont think they actually used them pre multi point like the 1.8.   Its a cross flow head too, which was used in the MK4 golf, So in short, you cant get 99BHP Out of a short block engine, totally diffrent.  The only gain from changing to multi really is a bit of throttle responce and better economy/cleaner burn,  but if your 1.6 short block is single point, it is possible to change to multi, but it means all new loom, ecu, keycode etc.. (post 95) Simply not worth it for that engine.




AFT  (or other 99bhp)




AEE (or other 75bhp)
