Tomei Exhaust Manifolfds For Rb26- Will It Change The Sound Of The Car?

[drifter 33]

hey,

im about to put gt-ss turbo's and tomei poncams on my gtr and im deciding if i should by tomei exhaust manifolds

iv done some reading and apparntly they arnt really needed but what i want to know is do they change the sound of the car?

basically i want my car to sound tough

thanks

[R31Nismoid]

sorry but i have to laugh...

want it to sound tough?

Thats your reason for spending $1000 on an item thats not needed?

You might aswell spend $800 on a set of big cams too that aren't needed

Honestly, it'll probably change the note a tiny bit, but nothing major IMO as the actual design etc isnt much different from factory.

It'll give you a little more power (by being less restrictive than factory), and probably spool the turbos a lil quicker... but its your money man.

I personally wouldn't bother unless the engine is 'built'

I was considering a set of these for my R32 GTR when I build it with a 2.8 kit.

For the dollar value are these a worth while upgrade option? does the quicker spool time and extra power justify the expense?

Has anyone out there done an actual dyno comparision of tomei manifolds vs stock in terms of spool time and net power gains?

cheers

Your car will sound tough if you gut the cat mate and all that costs is 50c screw driver and 10 minutes.. its illegal tho.. suppose u dont really care tho

1. no

2. yes

latest HPI mag did an article on unnecesary upgrades. R32 GTR making 306rwkw, they put stock exhaust manifolds back on (was tomei i think), stock cams back in (tomei poncams), stock fuel pressure reg (cant remember)back on and i think there were a few other things too, all in all the car lost 1kw, yes one, just ONE killerwasp

shure it lost one kw in the top end (peak power) but what did it loose in the low/midrange? torque? I dont care what the number on the dyno sheet says, its all about how the car drives and thats all about low/mid response and tourque. I would bet my left nut that it was a fair whack worse off in the mid range....

dont upgrade parts on your gtr, it will go faster. r31nismoid said so.

Gee thats random?

[VB-]

very random, and as for midrange power on the GTR, they were very close, almost a trace of eachother on the graph

just read it again, car as it was for the second run:

HKS GTSS turbos - as before

factory exhaust manifolds - were tomei items

factory cams - were tomei poncams

factory water pump - was an electric item

sard fuel pump and 700cc injectors - as before

doesnt seem right that the graphs are so close with a change of cams, but it sorta makes sense to me, it moves the power band higher where the torque is dropping off because everything else is designed to come in earlier, so it sorta balances out? thats how it works in my head anyway lol

and no, i cbf scanning it. next time u walk past a news agency just pick up a copy of HPI and go to page 56

he said nothing of the sort

SysLink67 on the other hand refered to a HPI mag article...

[R31Nismoid]

Got it in one spilmer, seems your not as dumb as your post would otherwise have people here believe

well then if HPI says so...... I thought that was a catalogue magazine for people who want to buy neons for their car. Actually did they find adding neons increased power? I was hoping to buy some, oh and a tomei manifold and order some take away...something with rice in it.

HPI Serving suggestion - rice.

To answer this blokes question properly the GTR 'is' tough... even to a deaf man.

[rev210]

to get a fully hektic sound block off the bov's & go the twin dose pipes uleh!

[bnr#@]

Also just replacing parts without a retune is not a fair comparison. The tune needs to be there to take advantage of the improved brething....

do you actually read hpi? find me one car, or one add for neons.

its a magazine, im not taking what they say as gospel, but its more believable then alot of other bullshit that gets posted on here...

It doenst make any sense.

Adding aftermarket parts doesnt mean it will give an instant hp gain.

It all depends on whether the car is tuned to the new parts installed.

[Tomei_Powered]

Dont believe everything you read.

Experience it for yourself if you find it doubtful.

Bullshits are everywhere!
