ok so i have an ef sedan and i put a t25 turbo on it.. and boom awesome one problem the the front subframe is in the way and i cant even put a down pipe on it! i tried flipping the whole turbo around and now im gonna have to make my intercooler piping do a complete 180 to connect to the turbo!....
basically i wanna know...
will running that 180 in the piping screw up the air flow.. turbo lag.. not as much boost?
or should i just cut into the front subframe to make a down pipe fit????

any advise would be awesome! please help me out.. what did you do to yours.. post pics and advice! thanks everyone
chris

 

i would think that it wouldnt have as much boost and yea maybe turbo lag will be more noticeable

 

see this sucks lol.. i dont wanna lose boost but i dont know if it will hurt anything to cut into the front subframe

 

cut the frame, and what fuel management are you using? (off topic but i just wanna know lol)

 

what exactly do you mean by fuel management? noobie question.. i know... and did you cut the frame on your car?

 

*facepalm*


op: i haven't boosted my ef so i can't tell you how best to route the intercooler piping. you could always upgrade to a different traction bar and then you'd have more clearance for the dp.

 

mines not boosed yet. i plan to and im looking for management ideas, as i want to stay obd0.

 

well im obd1.. d16z6... running 450cc dsm injectors.. with resistor box?

does anyone no if cutting the frame will hurt anything!!!!

 

ive heard of people doing it all of the time with no real consequences
i think theres a thread here were one guy cut into his frame for the piping

 

alright.. lmk if you find it and link it to me..
this is a budget build and id hate to have to dump boo koo amounts of money into a traction bar... i REALLY hope nothing goes wrong by cutting into the subframe

 

still looking for any pics/opinions/ideas ect! thanks

 

if you dont feel comfortable doing that then try to get a custom dp made

 

either way im getting a custom downpipe made.. its just where the dp comes off the flange the subframe is right in the way.. so custom or no custom im still gonna have to cut the subframe i think :/

 

lazy

 

did all of the above, cut front crossmember(radiator clearance) rewelded, cut frame(intercooler piping), cut bumper reinforcement(big *** intercooler) rewelded, no major problem yet, space was kinda tight for an ef compare to other honda like eg or ek, alot of custom modifications, as for 180degree intercooler piping, everybody did the same right? i have an 90degree before the 180, it still works for me.

 

Dude, your in the wrong web forum. real home made turbo dot com

Also, if your trying to stay OBD0 with a turbo set up your gonna have difficulty running a good program that has any sort of support for it. Turbo Edit is what i used way back when and it had its glitches. Do your self a favor and go with a chipped p06 or a P28 and run OBD1. Many more programs available for your tunning needs.
As far as your DP and Charge pipes. Your gonna have to do what ever it takes to get them routed. EF engine bays are crampedVS EG's and EK's so you have to get creative. What maifold are you running? HF with an adapter plate or a Ching chong meow???

 

don't cut frame. there's a thing called structural integrity and cutting the frame will definitely sacrifice this. people do turbo setups in EFs all the time without cutting the frame. either get traction bar setup or buy the correct turbo manifold.

why people will risk safety just to go fast is beyond me. the front cross member acts not just as a radiator support but also absorbs a good deal of the impact in a front end collision. if you cut it, you make a weak point and it will not absorb the impact but will fail and the impact will be distributed over other areas of the car causing more damage to the car and possibly yourself as well.

 

Then by that logic he shouldnt change he stock X member cause anythign else would be dangerous.

you can cut it and box in what ever you took out. but for the most part you shouldnt have to cut much.

 

^good point. But it also helps with traction! Thus the name traction bar. U will suffer with evey aspect of driving ur car, especially in the rain. Just redo ur turbo from the manifold up. Measure and measure again. Put thought into the path of flow. I guarantee that u will be more pleased if u think it out

 

wat?

 

Bahahaha!

i didnt suffer much when i ran mine. weird...

its must be something new going around. maybe it came over with SARS.

YOur in An Ef when it comes down to it. If you run into a car any bigger than yours your gonna suffer no matter what traction bar or X member you run. Just dont drive like an idiot and watch the road.

 

beaucoup
pronounced bow ku
not boo koo

 

A T25?
What header and downpipe are you using?

You should be able to copy the Greddy kit to get this going.

 

not really, no because there are not any "weak" spots on a traction bar. by that i mean they aren't notched and won't have a fail point such as a cut crossmember would.

you could cut it and box it in, yes, but about 1 in every 100,000 people actually do that.

 

for the record...
1. i am NOT lazy.. ive done more then enough research on this topic and cant find a post anywhere....honda tech has millions of posts..i simply asked him to link it to me because he knows of it so **** off...

as to everyone else i truely appreciate the imput...

i AM already obd1 so im really not too worried about it... its a z6 converted to obd1

i am using a HF manifold and when i bolt the t25 on im goin to have to cut into the subframe a little bit in order to get it to fit....

i wouldnt mind purchasing a traction bar but do they make them for the ef sedan??? is the ef hatch and ef sedan subframe the same?

where ever i do cut into the metal i plan to basically "box in" the down pipe by welding in new metal by doing this i dont see it being too big of a problem as far as saftey goes
