ok wen i first looked in to doing this conversion ( 1200 ute manual- ca18det) like 6 months ago i was told that the gear box tunnel has to be cut out heeps to fit the box in but yesterday wen to jap motors to get a half cut quote ($2600) and was told to buy a kit and it just bolts on no cuttin or weilding or anythink
i had got a quote from stainless customs on doing the diff and the exhaust and droping the motor in to the empty engine bay but now the guys from jap motors said that its eazy and i could do it my self with a $300 kit from them

any one tryed theese kite. is there any cutting and or major mods needed in the gear box tunnel. or any think else that would provent me from doing this at home.
thanks

if your 1200 is a auto you can squeze the ca18det wit box in ( i have heard )

but no way if your car is a manaul .

so for $300 wat exactly do you get ?

to cut the tunnel out and weld bigger one in you need grinder and welder can be dont in under 2 hours buy some one that doesnt know wat there doing .

if your useing the ca18det gear box you will have to move the hand brake

i think the japs are playing with ur willy and taking u for a ride on this

all i can say is have fun cutting and welding. try maddat they have premade tunnels and also premade crossmembers, in short check out there website www.maddat.com

I'll second the Maddat route, the blokes you spoke to sound like they're yanking ya chain.

yer go maddat or if you use stumpy gbox you could just use a mallet, worked okay in mine.

yepp R30 stumpy will fit, even with a manual tunnel it will fit, needs a massage though, S13 will not fit. needs to be higher at rear of tunnel because the shifter has a large housing and because the shifter is back approx 200mm or so,

thanks for the help, now about theese other gear boxes is the silvia box the best for this motor or should i just get the engine and buy the "R30 stumpy" that just needs the tunnel to be bashed a little bit, witch is best route or is there a nother way to go about things

also does the diff need to be changed to the shortend r31 for the stock ca18det motor or is it a good idear to have this done at the same time as the conversion... ive hurd of people keeping the stock diff in
any comments or advice would be great

thanks

Both gearbox options have their benefits. I currently have an R30 box in mine and it works fine despite a few whines ect. I am, however, planning on upgrading to the S13 box because I plan on making more power and the S13 box is stronger and will shift smoother in the high revs.

I have been running a standard motor with a bit more boost and the stumpy skyline is fine.

i went for the siliva box . i like where the shifter pops through ,

diff well the h165 will last if your nice , but one leggers get a bit boreing and its hard to put the power down .

if you have the coin go the better diff
