just got a 93 white 300 zx tt for 3 grand needs some minor body repiars but lets just cut to the chase. im wanting to upgrade the turbos to a garret t25r or turbonetics t28r turbos. the garrets come with a internal waste gate and have a capacity of 240hp and they are around $2000 for 2 of them where the turbonetics are external wg and cost $1600 for a set of 2 i need some opinions here on what ot go with and what manifolds are good.

i was thinking of getting the turbonetics and getting a set of tial wg but not sure what to do about dump pipes
then theres the bolt right in garrets no mods needed. would i get more power out of the internal or externals wg and what is easier to work with? what are some good manifolds to run for fair price and turbos and waste gates and dump pipes

you cant just upgrade turbos and expect results, there are a whole slew of parts you need that work together with turbos to make a lot of power. time to get out the credit card.

how much power do you want, whats your goal for the car, what do you plan to use it for? These are more important questions to be asking yourself than whether you need internal or external wastegate. And as a general rule you don't even need to worry about externals until you've got a 3071r or bigger on each side, because a 3" douwnpipe and turboback will easily support the flow created by the internal.

looking to make it a weekend warrior / show car looking to take it to shows and the drag strip. want the power and the looks to go with it but i want power first im wanting 450 - maybe even 600hp ive looked at upgrading the fuel injectors but not sure what size to go to a aem ems as well as other mods the greddy system has got my attention love the look and sound but also want a system that will give me the best performance for my money as well thats what i was wondering what would be the best way to go for power and budget if internal wg are good and easier for a weekend warrior and fir sine cruising around then that might be what im looking for im not wanting a all out drag car just to upgrade whats already there for better performance and some good boost im looking into running 10 - 15 psi 10 during regular driving and 15 for the strip

you need to do some hw, just some reading will help.
10-to-15 psi won't get you to your goals (in terms of power).
you need upgraded fuel injectors, at a minimum nismo555cc's.
you don't need the aem ems.

you cant have both of these! if you are starting from square one, 450hp will cost you about 8-10k. intake 3k, exhaust 2k, fuel injectors 1k, new clutch 500, new plugs 80, boost controller 500, chip 100 will get you to 400whp. you could get the 50 more with bigger turbos 2.5k, but then you run into upgrading more stuff while the engine is out. that doesnt include maintenance to get it running right before you start bombing cash into it. 600hp i dont even want to think about.

Minimum to make 450 is the BB530 or GT555R kit (you can run 28/25 hybrids but will likely top out at below 450 whp and they are extremely inefficient), bigger injectors and tune. However with just those mods the power will not be easily made and the car wont be efficient. Owning Z32s is very much like owning an older exotic, you can make the power yes, but nothing NOTHING is cheap and if you cut corners you will end up paying for it either breaking something or spending the money later on that you should've spent up front. As has been said many times before: Cheap, Fast, Reliable. You only get to choose 2 and this is especially true for the Z32.

didnt plan on cutting corners or buying cheap parts at all i was just looking for the best bang for my bucks when it came to the turbos. the 300zx tt i have is an automatic as well and was also looking at different injectors nismo was one of the choices i had picked out for it. the exhaust im wanting to run is the greddy turbo back ive priced out different stuff but also comparing the products in quality and efficientcy as well as best priced ill for sure spend more to ge the better product

to make things easy...jwt 700bb at 15-17 psi will get you around 450 rwhp with minor bolt on. simple list of stuff you need. go to z1 and check out their power packs this will give you an idea of the mods needed mike smith manifolds are not included in the list. then you can decide what you want and what you need. z1 turbos are a bit different then Jim Wolf. if you want turbonetics good luck cause its gonna be custom=a butt load of money for fab. or Greddy TD05s=4-5k

i decided to go with forged internals all new valves lifter ect. as well as bigger pistons and better rods and bolts as of turbos i settled on garret t2871r's with greddy 3 row fmic and intake with hks turboback system along with injector dynamics injectors and aem ems system with uego wideband and hks bov's and other parts . theres a guy i found with a fully built motor running upgraded turbo parts and tuned with garret t28s at 20 psi made 591 whp i was impressed lol

that's a lot to digest, the greddy 3-row fmic isn't the best solution, get aspec massives or the tdm fmic if you can.
two, the ID fuel injectors are great, but they're not bolt-on, you have to get either bde (recommended) or winfactory fuel rails.
are you sure you're ready for this kind of project? you were asking basic questions such as what manifolds to get, and now you're doing a monster build.

i was just asking and recommendations to see the quality and opinions of other parts that i was looking to get
