Ok, Obviously the Turbo or the Super is the next and End all. Cant afford 4500 bucks though.

Currently have CAI and Catback with Straight through Exhausts mid muffler delete.

Looking at "J" Pipe but not sure which one to go with, and then what is next after that? anything really worth the money for HP gains?

 

There was a gentleman on here who spent nearly $20k just achieving 325 WHP.
Just boost it, it's not cost effective to go full blown NA.

I had the intention of boosting my TL after I payed it off, but instead I am opting to pick up a boosted S2000 project car.

 

have you gotten hfpc or pcds yet? those are the best value performance mods. it will yield more power than catback and cai combined since its the most restrictive part of the exhaust system

 

cant do PCD's as its illegal in Oregon and no shop will do it. I read the J pipe with 3rd cat delete is a good buy. I wish I could boost it but again im in the 4 grand. I miss having a boosted car!

 

While that is true, I would say it's way to early to say that's the norm price for power. A j30a4 made 305whp sae. This is his mod list.

4in CAI wrapped 9in AEM dry flow filter
bored 3.7 tb,
3.7 manifold
ported & polished runners
TLs cams,
rv6 pcd, rv6 Jpipe v3,
2.5 - 3inch cone to 3 inch single mandrel bent exhaust
rdx injectors
flashpro

Notice he has stock heads, and only tls cams.

 

and that put 305 WHP? Not boosted or Super or anything? See that is nice. I would be happy with that as I dont mind donig the work myself as long as I have some direction and help on what to do and where to get the parts.

 

You dyno, 10-15whp over the accord stock so you could get more power if you replicate his build.

 

where is his build thread? Need my next step lol.

 

V6performance.net 7th Gen performance section.

 

then do hfpc. will pass the sniffer no problem. its not any less legal than the rv6 v3 jpipe

 

I would consider our XLR8 V2 j-pipe in your research.

I want that one so bad! the budget after the exhaust I just did is hurting though. I want that and the High Flow Cats. Then I'm done for a while.

 

I'm the one we're referring to with all-motor making 325 whp, lol.

Here's some additional perspective - i was making 295 whp with full bolt-ons and 3.7 manifold/TB swap and a tune on Flashpro. SO that was all before my heads/cams were worked over. porting heads, raising compression, and regrinding cams put me at 325 with a 4" intake pipe. This was all done on j35 heads.

So for someone to see 305 whp SAE with basically the same mods I had but also a 3" exhaust on a j30a4 accord platform, and on a different dyno, is totally realistic in my opinion.

The reality is that I have proven out that modifying a stock j35 head doesn't gain you much. I believe you can make more power by combining other J-series parts - this does take some trial and error but I believe the Accord guys have found a lot of success in that space. There are guys now successfully working in 3.7 components from heads to crankshafts.

all that said - there's a lot of kids out there on forums who spout crazy numbers about power and drag times without any proof - and just from swapping some heads/cams/cranks and adding dual-throttle bodies on an already efficient V6 platform that's naturally aspirated. There is a limit to power you can achieve on this engine without boosting and that limit comes very quickly. Anyone who tells you otherwise in regards to the J-series doesn't know anything and is setting themselves and/or you up for severe disappointment.

Stick with bolt-ons and a tune and hope you see 300 whp, and be happy if you're over 290. Going beyond that will require you to frankenstein your car.

 

ILC he has stock heads and cams. 305whp sae

 

Perhaps it wasn't clear in my post - i know that he was on stock heads and TL-S cams. I'm saying I had identical mods to him and made 295 whp SAE, with 1 exception being that he had a 3" exhaust dump and I was running straight ATLP v2 quads. So my point is simply that 305 is a realistic number given 3" exhaust / different dyno / different day.

and the bigger point being that it's totally realistic to be at 300 whp with bolt-ons and a tune, and that modifying the heads/cams isn't worth as much on the j35 - i.e. you aren't gonna go from 300 to 350 whp by porting heads and regrinding the cam.

 

The question to OP is... is it really worth it to work on a J-series platform? The car is ridiculoously heavy as a start, the engine doesnt have must supported aftermarket parts, the auto TL just does so horrible as a 60 ft at the track and lastly, the car just retardly oversteers badly. IDK, get into a better platform or work on this one to improve all areas to make it a race car... This car is far from being a sports car.

 

OP actually just PM'ed me last night asking for a bit more in-depth advice and I just got done responding to him with a similar message.

I used to have an '05 AT with mods like OP (plus I had PCD's) has and it just was not that quick. My stock 6mt Type-s beat it before I sold my '05 AT I had a buddy drive it against my 6mt and I easily took it in my Type-S.

I would stop modding it - especially given the car probably looks good already because OP has the a-spec, 18's, etc.

 

unless you're in my position with a blown engine. Friend over-rev'd my car! lol
I'm looking to do a Frankenstein motor.
3.7 BABY!

 

Friends don't let friends dial VTEC up to Super-Duper

 

Has anyone tried going with a small shot of nos (wet or dry) or is that not recommended with our internals ?

 

Yeah, I have it running good, sounds clean and looks sharp (IMO) so I am going to move onto a project car on the side, I really appreciate the advise from people as this is the first Acura / Honda I have owned that I have cared to work on so this platform is new to me.

I really appreciate everyone's help and input.

 

of course.

this forum is FILLED with great post about performance. this car came out at the end of 2003.
that's 10 years of cool shit that we have done here on acurazine.
please browse the TL performance section. there's lots of information on nitrous.
P.s. it's called nitrous and not nos. nos is a brand.

 

 

Lol Thanks. I thought nos was an acronym as well.

I searched but guess I have to dig alittle closer.

 

Not to be Debby Downer but maybe a different platform will meet your needs for the power you want. You mention money being tight but wanting more power, those two don't go well together. With all hp for $$ return on NA mods you might as well go Turbo.

 

Or buy an Odyssey.. lol. That platform sure seems lots of love on turbo!

 

What happened? Did he misshift ?

 

I was incapacitated at the time and let him drive.
just general tom foolery and hooning. he has a 2006 GTO, '84 monte carlo ss, and a '87 GN. he was having fun and so was I in the passenger seat.
I believe he was trying to find the sweet spot for third gear, as I was inebriated and was having a total blast when he would pull. if he exceeded 90mph in third on a down shift

again, not sure as I was impaired.

I havent asked him what happened, but we agreed that it happened after he drove it. Obviously, he's on the hook for at least some re-man. heads.


Ive PM'd Yungone501 and have asked for some options.


totally not sure whether or not to just get some 04-06 heads for cheap and call it a day

or go big with the 3.7 build.

 

What are the symptoms? CEL, rough idle, noise?

 

Sonnick has some MDX (I think they're MDX) heads he's been sitting on for awhile. Maybe he'd be willing to part with them. Maybe have Paul do some porting on them and slip in some Bisi cams?

 

the next morning, we knew something was wrong.
funny idle.

sounded like I was cammed.
always had a check engine light due to running catless, the stoichiometric mixture would be less than ideal.

since not DD, i left in the garage for a week. this weekend, I bought a OBDII scanner and read off some of the codes. misfires in about 3 or 4 cylinders, but I know that's not true.
usually just one cylinder with a bent valve or two.

I can tell it's not running on full power.

 

 

MDX heads seat on a J32?

Justn.. I have some heads sitting in the garage..

You want to borrow them?

 

you're not getting them back.
if I go 3.7 heads, i have to do 3.7 short block and different cams.

 

You really going 3.7? Shiettt.. I'd go small block v8 or turbo.

 

fuuuuuuuu. impossibru


i'll just buy a set of 04-06 heads for like 100 from a friend

 

$100?! is said friend retarded?

 

Homie price is at least $250.

Handjob and clean finish is $100.

 

I say scope your cyls, pull your heads, replace what needs to be replaced and be done with it. Hopefully no ringland, cylinder wall, or head damage.

 

i'm trying to score the heads first.
its still drivable right now.

if i pull the heads = no car = cant give dennis his wheel back = most elaborate ploy ever.
