another turbo ga16 question

NotAnotherHonda · Sep 12th, 2003, 02:44 AM

ok...i plan on turboing my ga16, and i was wondering:
1) can a apexi safc take the place of a jwt ecu....in order to save money....of course
2) since i have a maf sensor, do i HAVE to get a recirculatiung bov?
3) is 2.5, 2.75, or 3" exhaust recommended for a t3 turbo on a ga16?
thanks...let me know please....

1)yes
2)yes, i believe its a rule for nissans...something dealing with the idle
3)3" is always good

1. yes
2. you need to recirc. your BOV because it is metered air.
3. 2.5 is ok 3 is better.

1. yup.
2. Your car will stall out at idle if you don't and generally act weird.
3. 3 all the way.

ok...i got a price today from my boy whose selling the turbo and everything....he wants 400 for a 22" by 7" by 3" polished intercooler, and a fully rebuilt t3 turbo...the i get a protech mnifold, apexi safc, and ill find a recirc bov....then i get a 3" turboback exhaust and im good to go right?

no then you factor in hours of tuning time with the AFC... that could be a few hundred. and you need larger injectors too.

NotAnotherHonda · Sep 12th, 2003, 11:33 AM

oh yea the $400 was for the intercooler and turbo only....then a manifold would be 400, safc-250, bov-?, piping and installation- about 600...i got everything???

James · Sep 12th, 2003, 11:35 AM

add 300 in to your final price for just in case stuff... oh you need all the oil lines and fittings, silicone couplers (you do not want to use rubber) so that is another 250 on top of that... so add 550 to your total price and that should be close to what you're paying...

injectors...

dreadsword · Sep 12th, 2003, 12:07 PM

Injectors will be about $150 for 370's from a BB.

theres always something more thats needed. i say... dont ever give yourself a "final quote" and depend on that quote, otherwise things might arise and bite you in the ass.

how many lbs of boost do you plan to run? above 9, i believe, is when the stock MAF starts to max out; or can the S-AFC take care of this? havent used one before so thats why im pointing it out.

oh ya, dont forget all those misc things like gaskets, bolts, etc. fitting and S.S. line can really add up in price

NotAnotherHonda · Sep 12th, 2003, 06:50 PM

yea im tryin to go over what i will actually need....but yea i plan on running the stock psi of 7...no more on the motor till i atleast get the cams.....

NotAnotherHonda · Sep 12th, 2003, 06:53 PM

oh yea...if i run a 3" exhaust all the way out, i will probably have to take out the cat right? ind oing this, i would weld a bung for my rear 02 sensor, so would i still get a check engine light?

NotAnotherHonda · Sep 12th, 2003, 06:54 PM

damn...ok...1 more thing...can i use the sr20de injectors, or do they have to be det or higher? and do i have to upgrade my fuel pump when i do this?

370cc injectors or BB "bluebird" injectors swap in and will take care of that. I dont believe you HAVE to upgrade your fuel pump but if you want you can for a little extra piece of mind.

Question though, why are you running a T3 turbo?? Personally i would run a T25 or T28 assuming youre running boost below the 9si MAF limit.

NotAnotherHonda · Sep 14th, 2003, 08:21 AM

im gettin a reaslly good price for a brand new t3, and i plan on running 7psi on a stock ga16...im not ever going to go over 9....so i dont think the maf sensor should be a problem, and if i ever decide to go higher, ill simply sell this one for the money that a t28 costs....
