Ok i have a 1993 3000gt and i want headers to fit up to the td05 turbos i used the search feature with no luck it didnt really bring anything up i dont know if its a keyword thing or what so if there is already a post im sorry but anyway i have the downpipe parts off a eclipse and can use that to take care of 1/2 the turbo conversion the problem im runing into is the headers i could easily get aftermarket ones and modify the piping a little and then the flange but i was hoping someone made the headers for a reasonable price to fit up to the 3000gt. i looked at IPS and 3sx... 3sx wants 3 grand for a kit wont sell them indavidually and IPS wants 2 grand for just the headers and o2 sensors... haha yea that works if your made of money but i have paid for everything on my car myself and cant afford that 2k for parts that cost maybe 500$ maybe 100$ worth of metal... if that... who cares if its polished... does anywhere sell them for a reasonable price?

 

If you can't afford the parts, you can't afford the power.

Keep it stock until you can easily afford the upgrades you want for your car. You obviously have no idea how expensive modifying a car is, so I'd highly suggest doing some more research before you go crying about the cost of aftermaret parts.

Have you invested in a boost controller/gauge, oil pressure gauge, full 60k service with new belts, gaskets, pumps, etc?

How is your current oil pressure? Your clutch? do you have an aftermarket exhaust/intake that will allow those bigger turbos to breath adequately? Do you have an upgraded intercooler and IC piping to allow adequare air flow for those bigger turbos? How about fuel management? What injectors do you plan on using, and what are you using for fuel control? Are you capable of tuning? If now, how do you plan on paying someone else to tune it... that's going to be at least a 200-300 tuning bill alone.

You obviously have no CLUE what you're getting into. Work on getting some supporting modifications with your stock turbos, then once you've covered all of those available options, THEN look into some bigger turbos.

 

haha your funny dont underestimate me... I have a FMIC and a boost controller with turbotimer thats all digital, the downpipe and exhaust i had made for the car and with my knowlidge of physics makes me think it flows as good or slightly better than 3sx's. its 3in all the way a true 3 inch that is. i have 780cc injectors. the motor was rebuilt 2 years ago after i spun a cam from a 7k launch bored and built a little (the only thing that stressed it more than daily driving at the time so i assume thats what did it). my preturbo pipes are made by dejon and i have a maf and maf translator to control my injectors tuning it wont be that difficult just time consuming. i have an upgraded fuel pump and i tore my dash out to transfer all my gauges to sunpro (oil press/amp/motor temp) other than my digital boost and air fuel ones made by prosport that are on the side pod. I have properly taken care of my car unlike the person who drove it before me. its what i do for a living... obvously i do have a clue what im doing and understand how everything works... I am doing this on my own like i said so money gets tight from time to time and i will never pay 2000$ for 2 peices of pipe that is retarded... there is such a mark up on that its crazy im working on fabricatin my own now because noone replied. it isnt that hard just time consuming i wanted to be lazy and have them premade but that is way too much money if im right about the design im going with it should flow a little better because there is less "drag". My car is my baby i wouldnt do anything half way i make sure its done right. Like i said before im just not made of money...

 

780cc injectors with stock turbos? HAHAHAHHA talk about OVERKILL EXTREME! Anything larger than 450's is a complete waste with stock turbos. You're lucky to get full use of 550's out of 15g turbos.

Yea, good luck with that. What are you using for fuel control? I hope a greddy e-manage or AEM EMS. Anything less (re: s-afc, etc) can't handle that large of an injector.

But you're the expert... you obviously don't need our advice here, so why bother asking?

 

Whoa, let's not get hostile in here...

But why in the world would you have 780cc injectors? Girly is right, those are the definition of excessive for such a small turbo application.
Also, you should probably follow Girly's advice about building the components around the turbos first, then getting the larger ones. You need more than an FMIC, exhaust, injectors/pump to upgrade your turbos. I'd also be thinking about drivetrain and brakes as well.

To answer your original post, ALL of the header kits I've seen for the TD05 turbos are at least $2 grand, and polished. My brother did a TD05 conversion on his car and bought the pre-fab ones from 3sx. They fit perfectly. A custom shop close to our hometown quoted the job at $2,500 plus shipping.

 

"But why in the world would you have 780cc injectors? Girly is right, those are the definition of excessive for such a small turbo application."

Agreed this would be a Super overkill for the stock turbos. With the current setup i have i can control up to 940cc injectors and im assuming there would be a ~50cc tolerance (+ or -) i may need to utalize on my controller in order to run the car at optimal feed. I do think that this is a little bit of overkill for the TD05s (altho 3sx recommends 680-750cc injectors mysetup is almost the same as their max power setup minus the motor parts but that will happen in the future) aswell but im not sure if i want to get a supercharger/upgraded tdo5s and add it to the mix in the future and kept that in mind when making my choice and could be breaking 1kHP if i did decide to do so so my assumprion would be that i might need around that much. I actually installed the injectors during the turbo conversion so they were never run with the stock turbos but in theory with my setup i should have be able to run them with my stock turbos but i cant say for certain because i never actually did it. The turbos arent 15gs they are the upgraded 16G 50mm's aswell i should have prolly said that before aswell and i did some modifying to the intake areas of them for better flow aswell so they should spool a bit quicker than average and smoothed out rough spots in the housings to perfection.


Supporting mods- I do understand that with the horsepower gain i will need to upgrade other things aswell. But i am going to state right now that i know running those turbos all out would blow the motor. I dont trust the the parts i have in it now that is why i plan to run a maximum of 18 PSI untill the motor gets torn appart again and i upgraded the pistins/rods/cams/crank and get a good looksie inside to see whats happend since the last rebuild.

Drivetrain - I do know someone who had run i think 700hp @ 24 (dont quote me im not sure the psi but i know it was 700HP) psi on their stock transmission without it breaking and it hit the 10sec mark but i dont trust my car to run that much through the transmission too big a risk for me im only going to hit about 500hp max till the motor is built. There is a place near me that specializes in DSM's (which have a similar transmission) and built a transmission that held up in an 8 second talon that they also built so i figured i would go talk to them before i made my choice between DogBox or built transmission but thats next years project i should be fine till then till i decide what psi im going to run at depending on how everything is when actually driving the car after the upgrade i plan to work my way up to 15 and see what happens along the way.

Brakes - Well i have put some thought into this. Im a bit worried about it and will be watching carefully i do have upgraded pads but i also have experience racing and every time i slow down i Heel-toe downshift so far 1 set of pads has lasted me 2.5 ish years and they arent even 1/2 worn down i always downshift and leave room for stopping. I have looked into drilled and groved rotors and again have purchased upgraded pads but im going to wait and see what happens before making that purchase or any other upgrades to this area. I do appriciate the coment on this everyne else seems to think itll be ok (4 diffrent mechanics working on my little project 5 counting me) im with you on worrying about that but i think ill wait and see what happens.

If you can think of anything else please post i appriciate comments that actually help i know im going to run into things that will need upgraded and having warning ahead of time is nice that way i can be watching. I may have overlooked something so an extra opinion is always nice or if im thinking about something the wrong way.

Headers- I was afraid of that 2k is kinda crazy when you think about it though for something so small. Im going to make my own which i didnt like Ips's setup anyway i think it has flaws in its design that makes it lose horsepower/flow as for 3sx's theirs im mimicing on the front but the back im going with more of a stock design just modified i think itll have less drag and better flow.

3KVT is there any way you can get me more info about your brother's setup? like what he runs psi wise and anything else that may help me? or possibly an email i can get ahold of him at? Any modified upgrades that were needed im missing? What he has done to drivetrain and such? That would be really nice to talk to someone else who is running this setup. The other person i know isnt all that helpful he recently purchased his car with the Td05s on it and lives pretty far away so its rather hard to get any usable information from him... he has no clue how half everything works lol.



If you dont have a constructive comment i obviously dont need your help

 

"I do understand that with the horsepower gain i will need to upgrade other things aswell. But i am going to state right now that i know running those turbos all out would blow the motor."

I have seen stock internals hold upwards of 650hp. Not something that was driven often, but it's still holding it today (2 years of rarely driving and babying).

"I do know someone who had run i think 700hp @ 24 (dont quote me im not sure the psi but i know it was 700HP) psi on their stock transmission without it breaking and it hit the 10sec mark but i dont trust my car to run that much through the transmission too big a risk for me im only going to hit about 500hp max till the motor is built."

I meant clutch, flywheel, perhaps even master and slave cylinders. The majority of the transmission will take that kind of abuse, but getting the power into and out of it is where I'd be concerned.

"I have looked into drilled and groved rotors and again have purchased upgraded pads but im going to wait and see what happens before making that purchase or any other upgrades to this area."

I bought those "racing" pads for mine and got cross-drilled front rotors and it reduced my 100-0 by almost 10 ft. Just food for thought, I was very surprised by the improvement by such a small addition. Those stock calipers are extremely awesome compared to many other brake set-ups on similar cars (300ZX TT, Supra RZ, which I know are lighter overall, but still...).

"I was afraid of that 2k is kinda crazy when you think about it though for something so small."

Yes, $2k is nuts for a bunch of mandrel-bent and polished tubing, but compared to basic things for a VR-4, it isn't so bad. It's so hard to find anything mass-produced aftermarket for a VR-4 that you should expect to pay out the anus for anything you want.

"3KVT is there any way you can get me more info about your brother's setup? like what he runs psi wise and anything else that may help me? or possibly an email i can get ahold of him at?

I can get you a decent amount of info about it. I don't think he has an internet connection currently (he just moved), but I'll give him a call and see if I can get an e-mail.
I do know that he runs 18psi at the track and 12 on the highway. He takes it to work quite often actually. You'd have to tell him what you've done for him to tell you if anything is missing (as compared to his set-up). I do know that he has a stage Ii clutch and an insanely light flywheel. He also got a big brake upgrade with stainless lines and all of that jazz, but I can't remember what company he went with. Wanna say AP racing, but I'm not sure.
I know how hard it is to find good help, especially advice from someone who has the same set-up as you. I'll try to get his info, but I may have to be a relay-man for now.

 

wow thanks thats sweet you took the words out of my mouth on most the stuff you said. The 3000gt is a pretty rare car the only reason ive even beenable to maintain the one i have is because i get really decent discounts through our shop and people are willing to go a little extra since we have so many cars in and out at the shop a year. I only plan to run the 15psi when racing the nice thing about the digital boost controller is i can adjust it at any time inside the car ill prolly run a max of like 5 psi as a daily driver if that so for how much ide rarely use more than that i cant see it breaking that easy it isnt a drag car more of a street car that i have fun with and have even more fun on the weekends with the street crews around here. i cant wait to down some rich punk in a viper...that will be great hahaha I do know that the cluch is some kind of an upgraded one that was nice to see when i tore the motor appart but i dont really know much about it or rememer much, at the time i was more concerned with why the motor knocked. ill find that out when i upgrade the tranny or motor whichever is next i havent decided. Thank you for the help i really appriciate it anything helps. If you think of anything else let me know hit me with an email when you find out more ctt08@hotmail.com

 

I had this whole really kick-*** reply typed up... and Internet Explorer ate ****. damnit.

Maybe I will get around to re-typing it later today after I finish my coffee. *sigh*

 

Oh, I have plenty of CONSTRUCTIVE comments, you just don't seem to want to listen.
