Different turbo choices/nitrous for the ga16

akk51 · Sep 4th, 2003, 07:42 PM

what are all the best choices for types of turbos for b14's? i'm on a real budget but am wondering if a really small turbo would work and might be somewhat inexpensive? if so, what kind of turbo would work and any price ideas? or...if you guys think that for a tight budget nitrous is the way to go..how much do shops usually cost to install it for you? thanks

if you want a good inexpensive turbo for your ga b14 then i suggest getting a used t25 or t28 from a sr20det anything larger than that would be considered oversized for the ga.....

Yeah, I just bought a BB DET from sr20deforums for 175 shipped, in great shape, backed by the word of some respected forum peoples. Cheap, and well matched to the GA - should spool quickly and boost strong up to my target 9 or 10 psi. Anything bigger than a T28 is too much turbo for our restrictive heads, IMHO...

175 dollars...for everything? all you need to do is install? that sounds amazing, how much power do you typically get from that one?

dude, no.... search the forums... thats not everything needed. thats just the turbo. if you build a turbo setup its gonna run you ATLEAST $1500 bucks... and thats if you install it yourself. Do some reading up on turbos and read everything you can find. A good place to start would be the "GA16det or SR20det?" thread started by vashna. Theres some good info in there. Also read James' "How to turbo" thread.... search.

just stick with the turbo.... Nitrous isnt that much cheaper (a few hundred at the most) and you'll have to refill the bottle.... IMO, turbo is the wiser longterm investment for your moolah

$500 isn't that much cheaper?

rkeith · Sep 5th, 2003, 04:19 PM

well yeah, i guess it is

I was just implying that in the 'grand scheme' of turbo charging and nitrous I wouldnt see that $500 dollar saving as enough to sway me towards nitrous and not spend that bit more. Especially not when you consider the long term investment.... like the old saying: If youre in for a dime, youre in for a dollar. Might as well go the whole nine yards...

ok yeah, i thought that sounded way too good to be true...what all do you need ina ddition to the $175 turbo that adds up to $1500? how much does a shop usually charge to install everything roughly? and what would the power gains be from that turbo setup?

holy200sx · Sep 5th, 2003, 06:02 PM

piping, welding, oil lines, water lines, all the T's and tap's, intercooler, injectors, SAFC or JWT, Manifold, blow off valve, Downpipe flanges, gaskets.. blah blah blah

Check out the Project 200SX 1.6 Turbo in NissanPerformanceMag.com.

Yeah, 175 is for the turbo only, used, from an SR20DET. Its not too good to be true, but its only a small part of the puzzle.

I'll also be getting:
Protech Manifold: 400
Walbro Fuel Pump and Nismo FPR: 200
Intercooler - Used Starion: 250 (after custom install)
Injectors: 175
JWT ECU: 500
240sx MAF: 130
Piping and Install Misc Parts: 1500
Modine Rad: 180

So there you go. This is definitely not the cheapest buildup, but it should be bullet proof and relatively inexpensive for a 9psi setup. It addresses cooling (radiator), fuel management (ECU,FPR,Injectors,Fuel Pump), Intercooling (Starion), Boost (T25), and everything but spark.

Why don't you call Hotshot and see if they will sell you the manifold and piping....

The Protech "log type" manifold is a great option, but not really the best option for the Ga16.

from the articles:
The Hotshot manifold is a pulse converter manifold, designed to spool the turbo up quickly, using pulse energy from the motor, as well as heat energy and expansion of the hot exhaust gasses. By pairing up cylinders 4-1 and 2-3, the turbines is hit with 4 discreet pulses with every power cycle of the motor. This cylinder pairing also helps reduce power-robbing reversion and improves flow. This design is unique to Hotshot.

you don't have to worry about the Fuel pump or Regulator .. Project 200SX is still running on the stock fuel pump and making 233whp..

dude, read the 'ga16det or sr20det' thread like I said... or read James' thread in FI..... both are good threads about turbocharging our cars.... A SKILLED shop that knows what theyre doing would prob. charge about a grand or so

Hey Mike - thanks for your input - its great to get feedback on my plans from someone so deep in...

I had targeted the protech as its somewhat cheaper than hotshot, and their SR20 products are very well received. Piping I had intended to have done locally, as I'll need to get a bunch of piping work done for the starion install anyway... but good suggestion, and I'll follow up with hotshot.

Since were at it, what's your take on rad differences - the Koyo you use is bitchin' expensive all aluminum... the Modine I'm planning on is brass/copper, but I'm also considering the equally cheap aluminum Griffin... any thoughts on how these all compare to each other?

Thanks,
--Rod.
