Default J18a vs J20 diffrences?

My motor is shot.

I have a suzuki sidekick sport that has the j18a. I have read many posts on random sites that the J20a will probably fit up to the transmission. is this true?

The J20a was in the vitara,aero,and the sx4(before going to j20b) What are the diffrences if any other then attachements for each individual car. What im trying to ask is can i remove the parts that make it specific to the other cars and use my parts other then the cam sensor.

on the j18a the US model had a cam sensor where the distributor goes if im correct and the j20a has a black grommet where the j18a sensor went and has a cam sensor in the valve cover... my question would be will the J20a except the j18a sensor if i remove the grommet and use everything from my truck.... fuel injectors,ignition, intake etc....

what problems do i have ahead? I can get j20a's from the sx4 all day long.. and i read somewhere on here about a j20a having bolted up to a sidekick sport zero problems.. but that was from vitara!

there is only 1 post ever, here on mixing J18a and 20s.
he did put a j20 in to a sport (do a google xxxx site:http://www.suzuki-forums.com/suzuki-...ra-geo-tracker

to find it.

the j20 is stroked 18 they have same bore.
the combustion chambers on stroked motor are very different. (see CR calcs for reason , swept volume into chamber)
be care with rumors , check them out first.
im try into make Sport page. showing diffr. parts. (most are)

on the j18a the US model had a cam sensor (there was no distributor on any j18) and the j20a has a black grommet where the j18a sensor went and has a cam sensor in the valve cover..

the rumor is yes. the CMP that is called (or CAS cam angle sensor) the cams are the same j18/20 so it fits that , the only quesion is does
the CAS actally fit the base.
J18 CAS on to J20 engine.? why not try it. (1/2 the true is above)

(read the rules here)

iraq site:nytimes.com

im quoting google.
so using the example above.

1.8L or J18

in FF browser i dropped this line on the URL line. and bingo

1.8L site:suzuki-forums.com/suzuki-sidekick-escudo-vitara-geo-tracker/

this forum on a scale of 1 to 100 is a 1 on swaps.

try the 100 here
http://bbs.zuwharrie.com/content/topic,106238.0.html



keep in mind, most mortals never heard the word, J18, so dont expect huge j18 hits.

here is my browser directly search results with above command. 600 hits

ask Ezzie

http://www.suzuki-forums.com/suzuki-...lace-j18a.html

im jtgh back then.


the 2.0L is a Stroked 1.8 (same engineer, for sure) and my be just a (list of parts) on 2.0L eng. drawings. be the first to discover the truth its, not common knowledge. 1.8L is rare.

j18a 84 mm bore, 83 mm stroke
j20a 84.0 mm bore, 90.0 mm stroke

i think the stroke is all in the crank, no deck height changes. (im a good builder but stroking motors not, im too cheap $$$)

issues, sensors' ,diff, and missing.
flywheel marks
cam slots at rear.

we think the castings are close. (I cant speak for all 2.0L made , SX?)
ill look that up.


my comments are USA street cars. on the roads here.

perspecive, first know how rare something, is before buying something or trying to buy parts
any wonder why Aftermaket parts makers shun this era and maker and for sure SPORTS.?

the below is a SNAP SHOT IN TIME , 1998 (best i can dig up,)

Suzuki in 1998 was and UNDERDOG ( horribly so)
and SPORTS are a DOUBLE UNDERDOG ,see the numbers.

I keep a log file of all things on Suzuki ( our year ranges)
finding build data is impossible for GM.
but Suzuki bless them shares data. below , see SPORT and cry.
CYTD is current year to date.
see link to data here , Suzuki is FIAT like in USA.

http://www.kick-fix.com/look/underdog-status1998.html


i should make a SPORT page
listing all differences. (vast)
but again, we get so few posts on this topic.

i think yours will break that record. but we did have one guy here fixing a clutch , with no legs. i had to talk his mech through the whole thing
and we didnt know the clutch slave stroke , spec, 0.75 inch we later discovered it.
but yours is the most, aggressive (swaps always are) .

SO YOU TELL US. YOU will be the GURU,

i found that the J18cams changed to j20a cams at (-62g00){from 77E00}
@ VIN 108259~ (~ means and higher)
i have no idea why.
the first Escudo J20 has no ckp sensor but has same CMP as all j20s -65d00
the CMP on all J18s are 77E20 senders, so is unique.
those numbers are dash numbers, pn suffixs.

the first GV shows no CKP sensor.

given my dance through the huge parts lists world wide.
it seems that your cmp will fit that J20.
for sure j18 cmp fits the cam j20cam end. (now it a head issue)
so:
make sure the CMP fits the base of head. (left rear mount match up)

the pn on the j18 head is 77E00 (77E in suzuki world means j18 root)
the J20 head is 65G00
so my guess is different combustion chambers due to increased stroke swept volume
of the cylinder. sure is. huh, can't jam in 50 (200div4) cc to same chambers. No way Jose'
and for sure I have never measure the deck height on both motors, id bet near the same for other reasons.

so, the head may be identical in ITS out side form, they are not the same inside.
who knows , coolant paths?

so mount your CMP and tell us , the cam is same.

id didnt know the CKP is missing on some J20s. missing until SQ420V2 was used. later.
good to know. (this is world wide looking not USA 1999 (our year start)

all usa and canada j20s have that CKP sensor (99 is first year)
other J20s , some are missing, but are the castings the same... dont know. (non in USA to see)

yes, interesting topic.

that guy did run a J20 in his sport and DID not change the ECU, that is what he said.
and did change the CMP , in some way....
i dont remember but may just have simply swapped in the old CMP and fired up.
there is a tiiming freeze jumper on all J18 here.
at left strut tower, DLC2\
all this is on my timing pages. under J18

j18a sensor went and has a cam sensor in the valve cover...

this is not true.
the cams DOHC are in the head,the rear of the left cam drives the CAS
the case is mounted to the head directly behind that cam drive.
where did you get this sensor in the VC story?

btw , just because some , junk yard parts swapper says he found a fit, dont make it true.
Fit to him is "simple" it seems to fit. (or it fit and started, so what junk man)
Fit and run right are 2 diff things.
for example a J18 head machine fits a J20 block, but it dont run right due to excess 50 swept volume.
50cc is big time differences. see (per cylinder) (no thicker head gasket will cure that)

yes, i see on other countries the EFI and the spark and the CMP,CKP and CAS are all different. (so becarefull on the www, some may be talking about motors built long before 1999 in a country far way, dont mix that all up.)
focus on J20 from a spec. year, and model, and country, see why? "they vary"

is your j18 bad. you never posted that.
