Gtr Modification..

[02_FNE]

Hey ive got an R32 Gtr and i wanna do some sensible upgrades... and need some ideas..

Currently the car is stock other then coilovers, K&N Panel filter, and from what i can tell a Rein Hard exhaust.. (looks like a cat back)

so any ideas on what i could do next? open to all suggestions.. dont really wanna up the boost would like to find the power else where, im new to the turbo scene so want to learn..

also ive been looking at magazines with build segments but has anyone got any HPI mag Articles on the gtr?

I think you've got most of the basic mods already covered...you can remove the boost restrictor olive which will give you a couple more psi but on old stock ceramic turbos may not be a wise move. Im still new to the rb26 as well but I'd say upgrade to R34 N1 turbos with some 600/700/800cc injectors, a decent size FMIC and chuck a PowerFC in her and you can safely run 260-320awkw which should keep you happy for a while

Cheers!

1. Dump + front pipes

2. PowerFC

Their goes over $2k and will definitely make a noticable difference.

So dump + Front pipes.. how much am i looking at there..?

ive seen dump pipes on ebay for $170ish,... whats good? what to look for?

From Memory I paid about $1100 for HKS Dump and Front Pipes, and it will cost you about a grand to have them fitted...it is a bitch of a job!

I also added a Pair of GT2560r turbos's for I think about $2500 (fit at the same time as your Front and Dumps if you chose to replace)

Removed the boost restrictor and Made 315rwHP with a 12.6 QTR at 181kmh

Then I added a PFC ($1100 + dyno $400) upped the boost to about 18psi made 390rwHP and ran an 11.9 @ 190kmh

[PSI_GTSII]

For reference if your GTR is stock it will probably run around a 13.5 at 170kmh

Doesn't cost $1k to fit dump+fronts, my exhaust bloke has fitted xforce dumps to numerous gtr's from underneath with the turbo's still on the car. Yes it's a bitch but it can be done.

So you'd know how much it costs then?

If so please post a cost so as we dont fill his head with false hope, as so many of these threads tend to do.

I did not get much change from a Local performance shop from a $1000 to have my HKS / Greddy Front and dump pipes fitted as well as 2 x new Turbos, and a quick run up on the dyno

[benm]

I don't know the exact cost no however it is definitely under $1k to fit dumps+fronts. The reason it cost you so much is because you had your turbo's changed also which is labour intensive (8+ hrs which is still well under $1k).

oh ok, so either way though its not a simple thing to do,, fair enough..

so really if im gunna do anything more i might as well go all out with turboupgrades, powerfc, dump+pipes,

how does all this affect drivability? and reliability?

[GTRBOS]

get your dump pipes, fornt pipes, get a set of cam gears for more zippiness and quicker boost, ofcourse a apexi fc, your not required for a bigger cooler because stock gtr coolers hold over 300kw but if you got heaps of cahs lying around go for a trust or a arc or something, i got a trust one on my gtr and is excellent, just get a good boost controller if you got standard turbos because ntog ood taking the boost retrictor off with those turbos, you said you got filters and your cat back exhaust, put it to about 1 bar of boost and you should happily see about 230-240awkw and it will be a very nice street car just with those mild mods and then later on replace yopur turbos with something better, get some injectors, cams and you will see over 300awkw with a bit off boost and it will be lethal mate

actually wont cost nothing closer to a grand to fit dumps and front pipes,

chasers motorworks are fitting my cousins hpi dump pipes and his tomei cam gears in about a week for $280 but then plus tuning so maximum will cost him $400-$500, 1k is way too much, if you really want you can change your front pipes but ofcourse not the dumps, it will cost you about 1k to fit new turbos, dump pipes, front pipes to be fitted and tuned, i cant see it being more then that, anyway just letting yous guys know,

gl with it mate and i payed $1000 for my hks dump pipes and my bee-r fornt pipes FITTED lol but that was the bloke i bought my r32 gtr off about 2 yrs ago,

cheers tony

You got a budget?

1st of all get new Dump and Front pipes cause the stock R32 GTR ones a terrible. The Diametre is tiny and very restrictive.

If you don't want to boost up the turbos then exhaust is pretty much it. You can install twin air pods but I think most ppl here might say stick to your K&N Panel filter.

Keep your stock intercooler, blow off valve, don't need to upgrade these until heavy modification.

You could upgrade to a Lightweighted Flywheel, it can help with take off + upgrade to a heavy duty clutch.

[gts-4 dreamer]

why not just change them yourself? the bolts are pricks to get to and much wd40 will be used... oil even if its bad.. but otherwise... it wont be that bad.

just make sure you have gaskets ready to go on with your new parts and your great...

provided you have stands / role on's are easier, get under the went and remove the old exhaust... that is unless you pussies cant deal with a couple of bolts... shit a t25 isnt as bad to undo as t3's... they suck... >;p

be extremely careful not to snap the bolts.. if it starts to round.. just stop.. if you dont have a good set of tools don't bother i guess is the moral.

we arent talking about gear sets inside the gear box here... it's a piece of piss to pull of an exhaust.

True, I'm my own workshop. Saves some $$$

Pays to have a workshop manual too.

[02_FNE]

fair enough..

well i recently discovered that it had a dodgy little cat converter on there restricting the shit out of it.. so thats been upgraded today.. and my mate thats doing it is Phat Pipes in Brisbane here (Excellent Reputation) anyway hes also giving me a quote to do the rest of the exhaust ie. front pipes and dumps..

but tell me whats the real difference in dumps and front pipes from brand to brand..

as ive seen so many different ones including cheap shit on ebay for $200.. all 3inch mandrel..

whats the difference?

[02_FNE]

also having a full system how does that affect boost and or torque?

[GTRBOS]

it all depends what kind of material it is, some stainless is really shit but if you go for the hks or sopmething they are much better but in power wise they all do the same shit but its all aboutn reliability, dunp pipes dont give a massive difference but when you change the cat back and the cat or even get it highflowed or something(bash the cat out) that makes alot of difference but it is good to change the whole exhaust while your at it, i wasnt going to change my dumps until i bought new turbos but the bloke i purchased my car off had them there to put in this other gtr but i begged him for them and he said $700 and i negotiated with him so at the end of the day he supplied my hks dumps and also i bought bee-r front pipes which are worth about $600+ and i got it all for 1k fitted, i saved at least $1k just there, but mate just pay couple hundreds more and get yourself some good dump pipes, my cousin bought hpi dumps off one of my mates for $300 but they are second hand but dont seem to have any wholes or anything so even good second hand ones bro they all do the job mate

less restriction i really think mate, exhaust is probably the most important mod to change on any turbo car

+1

It frees up the exhaust flow allowing it flow quicker in resulting the car performing a lot smoother.

[02_FNE]

does the cat really make that much difference?

cos im getting a really good one put on as we speak, cos the one that was on there he said he wouldnt even put on his corolla.. lol
