hey guys, ive been waiting to find someone with good welding skills who will make my manifold for cheaply, now i found someone it can begin

im starting with
probbly a T3/4 ar.60 or 80 (huge mofo)
intending for it to spool round 4500rpm-5000rpm

initially running 3 psi boost (untill its setup for more)

my first aims are to get it working, dont care on initial power/boost

ive been collecting piping/headers and other things to help me in my mission,

ive got soo many questions its not funny


how much does pipe bending cost?
how thick should manifold piping be?? and how much would it cost
what material should i use for my face plates (steel), what thickness/material should it be?

my shopping list for boosting is
bigger injectors (L67 injectors probbly)
BOV
boost gauge
boost controller
external wastegate
new valve springs
diff upgrade to help put the power down

pretty much id be stoked if i pulled over 200rwkw and that is the aim

Get in the ute
not aiming to deter you at all! just some more questions to add to your list!

have you considered where you're going to put the turbo?
how you're going to run the dump pipe?
what you're going to do about oil/water feeds?
intercooling/piping?
what about your exhaust?
what about the poor auto?
how about the extra lots of heat under the bonnet?
you'll want your stall converter changed to suit boosty torque...

- standard single spinner diff should handle it if you drive gently...
- standard motor should be good for 10psi (ish)

check out a car called RAREVP from VIC .. it's a vp turbo 6 pushing over 200rwkw... home made looking setup from memory.. i reckon you could find a lot of good ideas in that car!

oh, as for pipe bending... if it's press bending then your local exhaust joint could do a lot of bends for you for a bit of beer... or a few bucks per bend..

face plates you can buy from ebay and lots of performance shops... just buy the flange that suits the turbo and weld it on the pipe....

apparently you can use vn v6 s1 tube headers as a good start for turbo manifolds.... otherwise you could find a set for a turbo buick in the states for a few hundred bucks, make a few modifications and bingo :)

Cheers!
Luke

cheers,

have you considered where you're going to put the turbo?
similar setup to V6 vengence

how you're going to run the dump pipe?
3" to the exhust, inbetween the headers and air intake with heat shielding

what you're going to do about oil/water feeds?
turbo im looking at is just oil, with returns to the sump

intercooling/piping?
similar to rarevp

what about your exhaust?
3" full system when the time is right

what about the poor auto?
stage 2 shift kit eventually

how about the extra lots of heat under the bonnet?
bonnet scoop with open vent?? maybe and more heat shields

you'll want your stall converter changed to suit boosty torque...
2500rpm, already looked into it

ive seen rareVP's setup its good as.. put alot of thought into it already!!

yes and vn s1 tube headers

and what about spooling so late? about 2500 would be better if thats where ur stallie will be for hard launch so when it gets to about 5000rpm it will have hit full boost

ok, i spent a good 3 hours at the wreckers playing with a vn, there was a s1 motor in the yard so i had to that to play with, then inside the car... decided on using S2 castie untill i can get extractors made as it does the job nicely and the s1 header just wont work...

also the piping is going to be run low near the sway bar (well above) then join to gether and come into the turbo from undernearth,dump pipe will then run straight down and run next to the header as low as possible ,

then ill heatwrap the piping to stop excessive reaching the inlet piping...

so far ive collected the manifold and some piping,

should i break the dump pipe into 2 bits to help when installing/removing it??? and have it bolt on...

im going to design/construt the manifold first untill the turbo, then get the turbo then do the down pipe... should have the first stage done in a month... getting all the pipes i need this week

the primaries will be the same length aswell

going to remove the aircon this weekend and do a test fitting of the headers before i go and get my piping/get it bent... then if needed make ajustments to the design

just so you all know, im not just throwing idea's around anymore, im actually doing this project... if anyway wants to help id be very greatful, even just idea's on how to make it better!!!

i just went outside and had a look at my car. seeing i have the manifolds off right now doing what you are doing.. and i see what ya mean. series 1 just won't work.. they hug the motor a fair bit. i put the right side on the left side and it was nearly hitting the AC. i know you are taking yours off.. but still.
have you thought where your exhaust will go after leaving the dump pipe. that is my worry.. i don't really want it lower than the sump or i won't have an exhaust in a couple of weeks of driving..
i spose you could go back through to the back between your exhaust manifold and your intake pipe. that would work i spose..
