Ok, so I'm considering (since I have to drop the engine anyway) going to a big bore kit (96mm) What exactly should I know, or what will I need to do??? I am new to Porsche and 914. If there is another thread somewhere on this, by all means please direct me to the right thread. Thanks, in advance, for everyone's help on this forum!! You've been great!!!

So basically what you are saying is that I can just use it with my stock L-Jet and it just bolts on, so there shouldn't be much of anything else that I would need to do? Right??

QUOTE(Beamer13 @ Nov 20 2007, 06:15 AM)  So basically what you are saying is that I can just use it with my stock L-Jet and it just bolts on, so there shouldn't be much of anything else that I would need to do? Right?? right. 1.8 bore is 93mm and big bore kit is 96mm. if there is not too much increase, the stock FI system can be maintained. i think i remember that D-jet can still be used for big bore but when the increase is alot (98-105mm), they don't work correctly. there are alot of if's, ands and buts to this but that's not the answer here to your question (L-jet on a 96mm motor). does that make the motor a 1911cc? i will admit on this board that i did not split the case on my 1.8 when i got it running. a previous poster referenced splitting the case and the majority here would probably recommend to split the case when getting the engine running. it's not that much more work and you then know the condition of the bottom end. that said, i wanted to get my 1.8 on the road to drive it and the bottom end only had 60k miles and the next motor to go into the car would be a 2L or a 2.056L anyway, so i had the cylinders honed and the pistons cleaned and put it together with new rings and installed the motor. flame on, Cap'n Attached image(s)
