This is probably a noob question, but do we need to do something to our headers if going the turbo route. Specifically, if I get obx or comptech headers, would I have to later change/modify them for the turbo kit?

dbramaged

you sir, are a super noob. to turbo your car, you would need a turbo manifold. the only way to avoid modifying your headers would be to have a rear mounted turbo under your rear bumper.

Thanks

I would sell the headers and get a custom turbo manifold made. If I was you i would avoid going turbo unless you like headaches and a car that doesn't run. Hope it isnt your daily driver.

inspiron0937

agreed its not a trivial task, i didn't get the headers yet just trying to keep everything in mind to keep my options open. don't like to redo stuff. does moderate boost cause issues too?

dbramaged

what do you consider moderate boost? 6psi on a 0.72 A/R is not the same as 6psi on a 0.57 A/R.

inspiron0937

without going into all specifics, my question essentially is would even a very low boost cause reliability problems in our cars as brian6speed mentioned. If so, what would be effected, engine, transmission, etc..? or is it the ecu that can't handle it? assuming I go untuned, would it be ok to just have a fpr to adjust to the air increase? but if you really need some kind of numbers then let's say for arguments sake 4psi.

dbramaged

Again, it depends on the turbo. 4psi on a big turbo isn't quite the same as a small turbo. A QUALITY FPR can help as well as modifications to your injectors & delivery, but the ECU is a bastard to keep things stable from my research.

Either way, if you're running an auto, I would try to stay N/A. I've already dropped my transmission once @ only 10k miles with it being STOCK and light on the throttle. It's a touchy bastard. I'm only doing bolt ons unless I find a good reason to do a 6spd swap & twin turbo set up.

inspiron0937

mine is 6speed. if I don't tune and just use the fpr would there still be some kind of issues with the ecu?

Ill post pics of my set up installed later tonight. I had no issues until I blew out a header to y pipe gasket. It was a cheap pepboys gasket. Blew out at 5lbs under half throttle. Haven't gone wot yet bc I'm not tuned. But car was running great prior to the incodent. When the gasket blew I melted a few wired and am misfiring on 2cylinders. Hipefully I fixed it all yesterday. Putting the car back together today.

I hate to sound like a dick but all the questions you are asking mean you should in no way attempt to add a turbo to a non-turbo car. It is a complicated process that done poorly will cause you car to be a mobile oil leak waiting to detonate.

The guys around here who have done it know enough about fixing cars to become mechanics (if they aren't already). On top of that, when their shit blows up (like Rajca's did) they are completely capable of diagnosing dismantling and repairing the damage themselves. Unless you have a good mechanic who is taking on this project for you and you have plenty of disposable income to throw at future problems I wouldn't recommend going turbo.

TheWeez

Well put. Without a great knowledge of turbos and building turbo setups, it's never a good idea to attempt with a custom setup. Maybe if there was a full kit but this is a totally custom job that requires a good knowledge before building and to get it running even in the neighborhood of right.

Add to things the lack of a good EDU management setup for the CL and it's a bit of a mess.

I don't think our engines are the best candidates for FI. Even with it, they don't produce all that much power. Seems most engines show much better gains.

inspiron0937

Thanks, I tried to look through your build thread but didnt find many pics of your setup, hope ure car is good now

mine never blew up. compression is perfect, just some burned wired that got melted together.

apparently im missing something. still misfires. im just gonna try to find a new engine bay harness

black label

Using blew up figuratively for "shit going wrong" like "blew out a header to y pipe gasket" and you are still having problems but you have the automotive knowledge to diag and repair the issues. Based on the the OP's question, he most likely does not have that type of knowledge.

thanks for your concerns guys, but i wasnt planning on making this a "should i or should i not turbo" it thread. original question has been answered.

Rajca, I ended up finding the pics of your engine with turbo setup it helped alot in understanding how the flow and piping works.

thanks all

mine are custom made. xs has a turbo kit for the v6 accord. but unless u plan on modifying the kit, i wouldnt recommend getting it

CLsuperhero

Get some manifold flanges from p2r and have someone fabricate a turbo manifold for you at a shop according to what turbo you want to use. I suggest copying what All motor did on this forum if you're building a complete setup. You are looking at 800-1000 bucks worth of work, but the welds etc. should be quality.

inspiron0937

so looks like it has to be custom, any way to get the turbo manifolds already made? I've never had any custom fabrication made before, do I just go by specs and dimensions or something like those plastic pipes that you form and then have them made off of that?

Rajca

iTrader: (8)

best way is to give the shop ur car so they can work around any obstacles they might encounter

dbramaged

I did a little research and ran the dimensions with my fabricating buddy, and we found that a twin Garrett T25 set up would not cause you to drop down to a small battery and the piping would run fairly easy. However, due to the downpipes not being "equal length" from the turbos before the collector, it will cause the car to sound a little like a Subaru. IF I end up going this route, I will just buy another header and have the turbo flanges welded to the 3-1 pipes, hotside=driver's side, run internal wastegates, 2"-2.5" downpipes to a 3" collector, 3" fast cat, single sided 3" exhaust with a dual in/single out intercooler as well as only run 4-6psi as well as a larger transmission cooler or 6spd swap.

TheWeez

Transmission cooler will do nothing to help with transmission life.

6-speed swap cost enough and is a big enough pain that you might as well just sell your car and buy a 6-speed.

dbramaged

I figured this, but I have an extra cooler laying around in storage. So, why not.

The only plan to swap it is if the new transmission takes a dump. I've only owned the car for 4 months and am on the second transmission (fully gutted, BRAND NEW internals & ported oil feeds) all while staying under 3k RPM 99% of the time. We shall see. I may start collecting 6spd parts over time and just do it one weekend. It wouldn't be the first time.

good luck making all this work with out removing ur battery and room for a down pipe. if u can do it, great. post pics thought bc ive ran several diff ideas and all of them i needed to remove the battery. then again, i do have a huge turbo

TheWeez

Cutting normal headers and fabbing on the turbo isn't gonna work. Sounds like your fabrication guy doesn't know what he's doing in addition to being lazy. If you're gonna do it, it only makes sense to do it right. Coming at it from the "these look like they'll fit" approach rather than looking at the functioning properties of the turbos you're considering first is the wrong way to go about things too.

dbramaged

I understand what you're saying, but he's actually an amazing fabricator. Cutting the headers is my idea of how it would be set up as a general guideline, but not the ACTUAL way it would be done. While looking for room for piping/filters/etc would require custom manifolds to have the turbos offset/angled/etc to function properly for the most practicality as well as functionality. So..... yeah....

here are my delayed pics

dbramaged

What about the intake piping, or do you run open element?

Rajca

iTrader: (8)

intake pipes are all 3". no filter

dbramaged

I was asking if there was intake pipe, not the charge and intercooler piping. Do you always run it without a filter?

Rajca

iTrader: (8)

Been running without a filter ever since I installed the turbo. No probles as of yet. Im gonna put in some mesh/screen so bigger stuff can't get sucked in. But theirs no room for a filter. Maybe if ij had a smaller turbo

inspiron0937

lol "maybe if I had a smaller turbo" when does the power kick in for you?

Rajca

U can hear is start spool around 3400rpm. And it screams just before 4k
