g93head/g94 block swap ?'s

bzmotoninja83 · Oct 26, 2009, 08:29 PM

hey all...... i have been reading and researching for a while and i have come up with a question. i have an 02 lancer ES 5spd. i was going to go the route of the g64 swap, then came the dohc g93 swap.
also i found that a g93 head with a distributor will work...i have seen the pic of said motor on the net somewhere. someone find it please???
..... i have the opportunity to aquire one of these. no manifolds but everything the head needs. i believe it can be done because there is a pic of a, what looks to be a us lancer with that head. valve cover is painted black. hope that helps someone locate that info...lol anyways the question that i arrived at today is,

1: what type of pistons does the lancer have? dish, flat or valve recess? ({DISH})
2: what does the 95 ish mirage 1.8 have? ({UNANSWERED})
3: how the heck would i make my ecu utilize the distributor instead of the DIS? ({WIRING})
4: ok maybe i have a few....... what should i expect power wise? ({UNANSWERED})
5: from what i can tell the bore is .5mm bigger on teh lancer and they both have the same compression but with a different stroke ratio b/t the 2 motors will i get a better ratio? ({UNANSWERED})
6: do i need the intake and exhaust manifolds? ({SAME, Thanks ThunderOZ})
7: off subject..... if i get teh 504 maf from a eclipse can i use those injectors? do i still have to flash the ecu? ({SAME, Thanks ThunderOZ})

ok i think i am done with the questions for now.... besides, the wife wants me to write her a letter this long atleast.....lol

I can answer 6/7.
6: The intake/exhaust mani flanges/patterns between the 93 and 94 are the same, so you don't have to swap them out.
7. You can use the 501 maf from the eclipse but why do you want use their injectors? They aren't that much bigger and they are low impedence last I checked so you would have to run resistor packs to make them work.

theres a place on my local lancer froum that is selling a dohc converion http://sclc.net/forum/showthread.php?t=6857

and their site is down right now for remodel http://www.llt-racing.com/

also forgot to say is that they are in austrailia

so anyone know what the pistons look like on both? want to make sure i am gonna have clearance before i start..... and do i use the lancer head gasket or do i use the mirage? the only diff i can see is one uses mls and the outside shape too........... hope someone can weigh in on this to show me the guiding light.

I can answer #3. You can't. Ignition timing control is an integral function of the ECU which sends a signal via the IGT wire to each coil, and looks for a signal on the IGF wire for ignition confirmation. There is absolutely no way around it. You would need to adapt the ECU and wire harness from the distributor donor car to fit yours.

Actually rabbit had a distributor on his lancer that kas built.

1: what type of pistons does the lancer have? dish, flat or valve recess?

They are dished...

3: how the heck would i make my ecu utilize the distributor instead of the DIS?

you wouldn't...
The distributor knows when to fire because it is hooked to a gear and knows when the cam shaft is in the right position... On your current 4g94 it uses a cam position sensor and the ecu uses that reading to tell the coil packs to fire...

so can i use the head with the dizzy? i saw it done. would i just not use the plugs fron teh coils an dwire it up standalone? i know yall are mad like + dont equal -....... and what not. is RABBIT around? what did 'KAS" do to acheive this? i know you cant plug and play and i need to rewire something..............
and thanks for answering the piston question.....

update!!!!

the head was a bust..... i was looking it over again and realized right before any $$$ changed hands. the head is a 4g64. and the timing gear on teh wrong side to boot.
:CRAP:
oh well...... back to the researching and drawing board. one of my friends was at the local pick-a-part and saw what might be a mirage. what cams will fit from the 1.8? one that has a dizzy or no dizzy? im leaning towards NO because no cam sensor and all........ also gonna to this TB swap i saw in here.

1g tb with 2g tps and setting it right and all with the ohm meter............

hey atleast im not posting "tore down" photos of "what ive done"........
({[fearthisrc]}) lol.... jus pokin at you.........lol
