How To Diy Turbo?
 

YES I'm a newbe.
But where can I find "tried and true" specifics on building a DIY turbo?
What manifold,downpipe,coolant/oil hose etc,etc?
My attempt at seaching "DIY turbo kits" for "how to" came up with nothing.
Am I searching incorrectly?
Please direct me.

I read your thread "DIY turbo faq".Great theory but looking for specifics.

It's somewhat unlikely people will give you a shopping list for a DIY setup... unless it's a kit-based like Begi-S/MSPNP/intercooler - see how easy that was?

Keep reading, and then you will figure out what you want / need and whether it is good / bad, and you can make the call on it.

If you are looking for exact specs on what to buy then that isn't DIY.

Braineack's thread more than covers what is needed to know for DIY.. Read it again if that doesn't give you what you want then I suggest you go with a kit.

How could one be more specific? If you need to buy a kit, then buy a kit. But that's not very DIY is it.

here's specifics:

buy a BEGI S2 kit. read the manual and follow it while installing the kit. enjoy the boost.

DIY should be renamed to DIFM (Do It for Me).

ROFL!!
you guys are great!

So nobody buys a manifold from here and a dp from there and an IC elbow from store X.
If I don't buy an already turboed car then I want to put together a really good homebuild on my current car.
I already have MS ready for install.
Is Begi the current hot ticket?

A lot of us do but before we ask we do our research so we can ask specifics about the parts and not use the shotgun approach. a simple search for "Turbo Manifold" should give you most of your options. It's up to you to weed through all the crap.

BEGI is good stuff.

help the guy out
buy whatever turbo you want, buy whatevery IC you want, buy whatever fuel management you want as in MS...now
go to store and buy welder, grinder, a bunch of pipes in various sizes of your chioce
now cut and weld until you have a manifod, DP, rest of the exhaust, IC piping.
when you are done here, install on car and then remove and fix whatever you fucked up so far....
once it all fits, you install remainder of needed stuff, like oil feed, drain, BOV, WG if external, and while attempting install fix everything else that you fucked up...
its a neverending process...for some people it just makes more sense to buy a kit...its cheaper too but shhhh. dont tell us
good luck, DIY'ing a turbo kit is not a walk in the park

"diy turbo kit" <--oxymoron

yeah, we buy shit from here and there and store x. but there's tons of heres and tons of theres and a bunch of store x.

just pick the best performance or best value from each place that you like.
mix well.
bake at 1600F for 45 minutes.

it's really all about budget.

small budget: cheaptastic DIY
small-medium budget: basic kit/decent DIY
medium budget: standard kit
medium-large budget: kit with custom mods
large budget: super custom DIY how you like it.
you dont have a budget this big: call up a shop and say "I want 400 rwhp" and have them design it.

i love the order of budgets, that is so true

i should have put "time factors" in there. time available is inversely proportional to dollars.

now if you dont mind, i'm going to drive my super custom diy jobby home before the sun goes down (yay dst!)

So if we're talking kits,the basic Begi is about the same price as th e FM basic kit.The prices increase as you add fuel systems.
Any preferances between the two and why?

Here's my original list:



I used a 9/16" drill bit to drill the pan. And a 3/8 NPT tap.

I used JB weld on the pan to oil return fitting.

I did NOT use sealant or teflon tape on oil lines anywhere.


Summit Racing:
2 @ 3/8 NPT to -10AN fittings
2 @ -10 AN hose fittings
3' -10 AN stainless steel line

JGS Tools:
1 48" GT oil feed line. Comes w/ t's and 1/8" BPT adapters, ect...
Also need a 90 degree for top of turbo, used a brakeline 'T' and just plugged the top.


Water lines:
5' of 5/16" ID Goodyear oil transmission hose to use for the water cooler lines.
2 @ 1/4 NPT to 5/16" hose barb fittings
1 @ 5/16" hose barb.
4 @ 5/16" hose clamps.
Used teflon tape on NPT fitting into turbo(water lines only)
Spliced onto thermostat housing, and just 'looped' the turbo into the circuit.

CircuitMethod.com:
HKS Manifold
Needed to add EGR fitting.
Drilled in the spot in the bottom of manifold that looks like a casting process plug about 1/2" around.
Used a 11/32" drill & a 1/8" NPT tap to make hole under/in the manifold.
Screwed in a 1/8 NPT adapter to 1/4" brake line.
took a 1/4" * 8" brakeline and bent into a U shape.
Sawed the OEM nipple (male)for the EGR fitting off flush with the OEM headers.
From the backside of the nipple drilled/bored it out to 11/32".
1/8 NPT Tap from the backside(tap only will go down about 1/2 way).
Screw in 90 degree 1/8 NPT(male) to 1/4" brake line fitting(female).
Reconnect modified nipple to OEM EGR compression fitting, tighten- make sure 90 is facing downward.
Now when the manifold is bolted on to the manifold the u shaped brakeline will connect the manifold and OEM EGR line.
Took less then 10 Minutes and about $5 in parts.

NICE.......^ Or you can download the greddy list off the support page and it's the basics to get started.

A parts list won't help if you don't know the theory behind it anyway. Once you know the theory the parts list is easy to create.

i agree:)

thanks Jefe.
As for theory we can always learn more.
I have been a certifed auto mechanic for 20 years and an enthusiast for longer.
Braineack's thread is awsome.
