Im thinking of getting some of these mods or getting these mods how much horse power should i expect
I have a 2004 5AT g35(280 hp) non rev up

Mods:
Stillen intake+Ztube
5/16 motordyne iso thermal spacer
Unorthodox racing pulley
Ark Grip Exhaust w/Motordyne Art Test pipes
Osiris Ecu Tunning

also if you can give a mod by mod break down on how much horse power i should actually expect that should be nice

 

A million. OK, not that much. Probably about 20 or so additional horses to the wheels. If you get a test pipe or HFC, you should be able to put down about 10-15 more after the tune.

IMO, pass on the Stillen intake and get a revup intake box w/ a good filter, and skip on the pulley and get the Transgo kit and higher final drive instead.

And don't forget to get a map for 100 octane gas. You can make another 10-15 on 100 if you get tuned for it.

 

He actually has art pipes listed next to his exhaust

 

Fantastic addition there dominate. At least dofu answered the OPs question to an extent.

 

Dofu didn't realize he put art pipes. Dofu stated with hfc/test pipes expect 10-15 more. I know art's aren't conventional test pipes and they're supposed to be better or something. I said in a non-rude manner that he had test pipes listed, to alert Dofu so he could give him a better number. Who knows, maybe art will give closer to 20 with those mods rather than 10-15 with a conventional hfc/test pipe? I didn't answer the OP's question because I don't know enough on the subject and am not gonna give false information. Rather I just wanted to help the OP get a better ballpark.

Thanks for the post enforcement though, officer

 

No. Test pipes after i/h/e will make about 10-15 more horses once it's tuned. Hell, they might make about 10 after a tune by themselves.

 

So your addition to this thread is where? Don't get your panties in a wad.

 

Depending on your altitude I doubt you'll exceed 250hp on an AT platform on a dynojet. Don't get me wrong they are all solid mods in your list- the g just doesn't respond well to breather mods. The tune will get you the bang for your buck- but the smartest comment above is to invest in the transgo. Best. Mod. Ever. (for the at).

 

I would like to see some kind of proof of this extra 10 whp you can make by tuning on 100 octane. 1 it's impractical since you'd have to pretty much completely empty the tank then refill with only 100 to use it, 2 you would have to get a completely different dyno tune with that fuel to effectively use it, and 3 a stock non revup VQ35DE is
No where near capable of utilizing it. Maybe if you threw in some hi comp pistons and such we'd talk, but EVERYTHING I know about this engine is leading me to call BS on this one

 

hmm so according to people's opinion i should go with
stock rev up air box+z tube
5/16 motordyne iso thermal spacer
transgo kit +higher final drive
motordyne tdx2/Motordyne Art Test pipes
Osiris Ecu Tunning

anyone know what tuning company would be the best for these mods and how much would each of these mods cost

 

You don't need the iso thermal spacer, save some money and pick up a used basic or 150 in the classifieds. Transgo and gearing absolutely yes but not cheap, find a reputable shop that's done them before and just do it. If you go bargain shopping and they mess up your trans you will be hurting for $$ big time.

Unorthodox pulleys don't do, barely make any difference and for the added risk to your engine not worth it IMO.

ART pipes are fantastic. Expect to spend around 500

Why ARK exhaust? Pretty much all cat backs perform the same, it really just comes down to looks and sound.

Osiris tuning anywhere from $300-800 depending on how and where you get it done, with $300 being just for the flash license and one time tune with no dyno, $500 for the license and cable from uprev, or $600-800 for just the flag and tune at a shop, no cable.

There's a serious limit to what a non revup DE with stock heads can make NA, I would recommend saving money on some of these mods and looking into suspension upgrades and an LSD

 

so if you had $4000
how would you upgrade your car without getting s/c/t/tt or nos or FI
for best performance

 

4k you should get plenum spacer/longtube headers/single exhaust/light weight driveshaft/ams pulley/rev up box with knn drop in/churches tb spacer/cams and tune that comes out to lil less or a lil more.. just got to shop around instead of the cams maybe some light weight wheels or carbon fiber stuff!! but for 4k why not just by a vortech and slap it on and youll get like 30more hp then all of the stuff best and the easy way to go lol

 

all them mods are way more that 4 k. cams alone with install is around 1800 - 2k.

 

plenum spacer
cams
HFC or TP
long tube headers
1pc driveshaft
tune
3.7fd gearing for 5AT +TransGo or 3.9fd gearing for 6MT
