GTi-R Swap

[Ryan Le Gros]

	Great source of info for the swap. AFAIK however you can use the radiator
	fans from the clip if you continue to use the TMIC, the ga16de fuel pump
	will be fine at stock boost, but if you raise the boost levels at all be
	prepared to upgrade. Im working within a budget so I will be adapting my
	GA16DE harness to work with the GTi-R ecu and harness as well. Jim Wolf
	Technology emailed me a ecu wiring diagram for the pulsar, it is as
	mentioned however in japanese, luckily i have friends who read and speak
	japanese fluently and they are in the middle of translating it as we speak.
	as soon as it is done Clark wants me to email it back to them at JWT so
they
	can redistribute the translated version to needy customers. If you retain
	the TMIC be prepared to cut a hole in your hood or use the hoodscoop from
	the GTi-R clip and transplant it onto your stock hood, the TMIC will not
	clear a stock hood and even if you have some form of aftermarket hood that
	it does clear, you absolutely must have a cool air flow running into the
	tmic via a vent or hoodscoop (hoodscoop being better than vents). The
	problem with the TMIC is it sits right on top of the motor, and heat rises,
	so its efficiency is retarded by the heat from the engine rising up and out
	of the car. One thing, that is extremely important to mention is to upgrade
	your brakes to the AD22VF's from the clip or get a fastbrakes upgrade. Your
	stock GA16DE brakes are absolutely not suitable for this motor, and you
will
	kill yourself and other people if you dont heed this warning.

	Save yourself a lot of time and money sourcing parts by buying a complete
	front clip. This way you know you are getting everything you need to make
	the swap work short of the transmission, axles, heater hoses, axle mounts,
	motor mounts etc. I bought my clip shipped from canada on ebay for 2500
	(thats including the shipping) the clip itself only cost me 1525 dollars.
	You will have parts left over that you can resel back on ebay, and you will
	have the luxury of using parts like the digital climate control console and
	the gauge cluster from the GTi-R.

	You cannot use the GA16DE tranny obviously, the bellhousings are completely
	different amongst other obvious differences. Get an SR20 Tranny, 3 of the
	bell housing bolts will not be used, you will just have to deal with it. I
	believe 1 of the axle mount bolts on each side will not be used either. The
	fly wheel bolt holes will have to be bored out to 11mm and the flywheel
	itself will need to be resurfaced. You will need to fabricate or have
	JGYcustoms.com fabricate you the throttle cable and cruise control bracket
	as well, jgy sells the brackets for 15 bucks, or just make one yourself if
	youre lazy or dont have the tools neccessary to do so. Make sure you get an
	LSD tranny without the 5th gear popout problem, and if you want to make
sure
	your tranny is going to hold the power from the GTi-R motor without
	breaking, shotpeen and cryo the gears, or better still buy completely new
	gears and have them shotpeened and cryoed before even installing them. I
	havent checked yet, but if you are swapping from an automatic to the manual
	(as I am) you may need a new crossmember as well, but this I have not
	confirmed yet. The GTi-R comes equipped with ABS, if you are fortunate
	enough to have front and rear wheel disc brakes this can be converted over
	to the sentra/200sx but it will add time and money to the process. the old
	ABS systems arent that great anyhow and youre better off yanking it and
	selling it for parts money.

	DO NOT MESS WITH THE THROTTLE BODIES, if you try to adjust them yourself
	youre in for a world of hurt in that getting them readjusted properly will
	subtract years from your lifespan and add much grey hair to your head. Just
	start with obvious things, you are going from a GA16DE to an SR20DE
	essentially, and that swap is well documented, get those parts first, then
	focus on going from the SR20DE to the DET replacement parts.

	As a final note, I am taking detailed and lengthy camcorder footage and
	photographs of the swap as we go (going from a 98 sentra gxe to the GTi-R
	motor and a 5 speed tranny swap), however I have nowhere to host these
	pictures, footage or the writeup i intent to do after the swap is
completed.
	If any of you have a webspace provider or have a means to hook me up with
	webspace that wopuld be great, this is a neglected motorswap as far as
	documentation is concerned, but for those of you who want to squeeze as
much
	power out of an SR20 as possible this is the way to go.

	Ryan
