ok so i recently purchased a turbo kit from a guy that was using it on his s14. it isnt any brand name kit but one that he pieced together. first off, i have garret T3 turbo with .60 trim. i have a log style manifold that is already welded so that it doesnt bust. next i have a vortech 8:1 FMU and a custom made intercooler for the 240. all of this will be goin on the car hopefully over the summer but right now im just trying to get the odds and ends so that i wont have to worry too much about buying parts that are necessary when we do the install. i already asked about the MSD ignition thing so thats under works. my mechanic will be sourcing the gaskets and lines and we have the hook up on a 300zx fuel pump. i was reading a thread about using stock injectors but i wonder if i should upgrade them? the guy that had the kit before was using stock injectors and was boosting around 8 to 10 psi. am i ok then to use the stock injectors if he was using them? another question that i have is the exhaust. it would be a very wise move for me to get a 3" exhaust b/f the turbo goes on right? and last but not least, i read a thread about the air to fuel ratio gauge being useless. should i just stick then with the boost and egt or should i get it?
BTW, i know i need a downpipe, intercooler piping and a blowoff valve so im workin on those. anything else that comes to mind?
My turbo kit, trying to work out kinks before it goes on
well im not sure what you need because you didnt say what came with the kit. a 3" exhaust is good for the turbo and should be more than enough if you are only gonna be boosting around 10 psi. the A/F ratio gauges are not a complete waste as they will give an estimate of the A/F ratio but if you are really conserned about it you can pay a bit more a go with a wideband A/F ratio which will give you the exact fuel ratio. widebands are a bit more expensive ($340 from ka24de.com which is a pretty good price) but will provide a lot of information when tuning and insurance when on the street.
well all that i said is what it came with. turbo, manifold, FMU, and intercooler. its not really a "kit" but then again, those are the main components of a kit. u get the point tho. i know i need a downpipe, and blow off valve and gauges for sure. but i just wanted to know if i left anything out in the previous post?

An air fuel computer wouldn't hurt, especially since your running stock injectors. Its not necessary though. The EGT is very important though, pretty much shows you when your engines gonna pop. Oil lines are a must, if your turbo didn't have them with the kit, your turbo's not gonna last too long (hell even the vw 1.8t with the little **** turbo has oil lines). Not being mean, just your tubo loves oil. A turbo timer to go with wouldn't hurt either... but staying in your car to cool it (the turbo)down isn't too bad. The guages aren't the end of the world if you don't have them right away... but you should get them soon, especially if you plan more boost. Like _ my greddy turbo kit doesn't come with any guages, but it does come with an air fuel computer (emanage), and oil lines. Also bigger injectors. And that pushes 6.5 psi without an intercooler (although i'm adding the intercooler) So, if greddy puts that in the kit as base items, odds are its a good idea to have them. The injectors are 370cc, and a good upgrade from the stock. You can find those off a 300zx. Oil lines, you'll have to rig that yourself. And the Apexi AFC 2 is a great way to adjust the air fuel setup, and help you run that turbo nicely. Hope this helps ya.

Oh yeah, and the 3" exhaust is a VERY wise idea. You'll get more hp and tq out of that turbo. You may want to swap the cat for a high flow one though, or test/strait pipe. If your gonna push more boost at least. You run the chance of blowing it out (the Cat), which would not be fun (especially if you just put the new exhaust on). Not saying it will happen, but the chance is there, and you need to factor in the life of the cat, the psi your pushing, and the EGT increase. My pal's old 93 Prelude blew his cat out by down shifting into high RPM's, and he had an aftermarket cat-back exhaust too. You might want to try it on the stock exhaust while you have it, see how it sounds and holds up, then if you decide it feels restricted or what not... upgrade to the exhaust. Hope this helps (again) Take it easy
ok so i just won a turbo timer off of ebay so thats off the list. all the oil lines and gaskets my mechanic is handling. the injectors is still up in the air. the guy was running with the stock injectors but if i upgrade them, then i will have to also get an safc or some other piggyback to let the comp know whats goin on. as for the exhaust, i have a racing cat chillin at home but the cat on the car was gutted out about 5 years ago so its really just an empty case. i blew it along time ago so we decided to just empty it out. lol. o ya im in fl so no emissions. im looking into an apexi dual for the exhaust so im workin on that. any other suggestions?
I think when I get to this point I'll go with this one:

Lots of people like the LM-1 over at http://www.ka24de.com I know I would like to pick one up just for the extra little bit of safety and to see how my EGT's correspond to A/F ratio
