Wanted to see what you goes would get first. I have a Jdm 4to1 ported now. Looking to add both in the future, wondering what wil give me the best results. More power or better acceleration.

 

FD, hands down.

 

A good number of people on here are going to tell you to get ATS, not the JDM FD.

Edit: I forgot to add that if you already have the jdm 4-1, I'd go FD hands down.

I'd do the final drive when you have a clutch and flywheel! Since you already have a JDM 4-1.......might not get a Toda header. Do what you want.

 

Go with the FD, and maybe a new clutch depending on the miles/abuse on the one you have now. I wouldnt waste the $ on the FW, though.

 

ATS.

 

the only reason i asked about the header is because I have seen 8 to 10 hp gains at the wheels from the header over a JDM 4to1.
Thanks for all the replies, gonna go with the final drive first.

 

The toda gets an additional 8-10 whp over the jdm 4-1? Are you sure about that?

 

I would do more research on the ats or jdm fd if I were you. Understand how a lower fd isnt always better, and in some ways it is better.

I have the ats fd though, and I like it....

 

Maybe with big *** cams but not with the skunk stage 1's, that for sure. With the JDM 4-1 and the Toda header I had the exact same HP. Only difference was the a/f ratio.

 

I've had both. My experience is that the JDM Honda 4-1 and the Toda are pretty close in peak numbers. However, the midrange improvements with the Toda were very noticeable.

For the record, I have stock internals, and stock cams

 

I saw Mike K's car on the dyno and he change from JDM 4to1 and exhaust to stock itr exhaust and toda header and gain 9 whp. I have stage 2 skunks. I don't want to go with ats fd because i think it is to close from driving cars with similiar set up except one had JDM FD and ONE had ATS FD.

 

Was this a flat out switch with no tuning or after tuning of both headers?

Tuned

 

english muthafucka, speak it.

 

 

Um, what D said.

 

thanks guys for all the responces. I will post the dyno numbers of before and after, when i dyno the header.

 

I like them both. Still currently have both. Although I got both at the same time, if I had to pick one or the other, I'd get the JDM FD first.

 

ats

 

I compared the Toda vs a stock(non ported) jdm 4-1 a while back, the gains were between 8-10hp under the curve and about 3-4hp peak. The tighter final accelerates the car nicely, but its a toss up ... either one will give a better seat-of-the-pants feel. If you have a clutch and flywheel waiting already to go in with the FD job then do that I guess, but definitely the toda header will feel very good for the money.

With what cams?

 

whats a good header for a 2.0L R motor... i have a JDM 4-1 now and i hear its too small. im thinking i need to upgrade to Toda/JUN.

thanx

 

SMSP makes a B20VTEC specific header I believe.. dunno who else does

 

forgive my ignorance, but what is an ATS?
