R34 Gtr N1's - With Fairly Stock Rb26dett Engine...will This Be Okay?

[nsta]

Hey guys, ive got a fairly stock r33 gtr rb26 engine, and have found a really good price on some r34 gtr n1's....and wanted to replace the ceramics with these as i know the ceramics can cause alot of pain to the engine if they let go!!!

Do these n1 turbos need any modifications to fit to the standard manifold/dumps etc....or is it direct bolt up?

Will i be okay running these turbos if my rb26 is not mofidfied highly?

mods:

acl forged piston (.5mm oversize)

1.2mm thick headgasket tomei

arp headstuds

3" exhaust

ARC panel filters

no other mods, and factory ecu...would this be a wise idea, i just dont want to ruin my rebuilt motor by keeping the ceramics.

thanks

yep it's a great idea. with 1.2mm gasket and forged pistons you could quite happily run up to 20psi providing you have the fuel supply and cooling and tuning to support it.

Spend the extra and get a set of exhaust manifolds and dump pipes to suit whilst you are at it.

Ive got The r34 N1 Turbos Good Choice Perfect Street Turbo , If i was You But i would Get a Aftermarket ECU Apexi Power FC , Fuel Pump And a Good Set of Injectors . With these Mods and your Mods Car Should Run Great ...

Can i not use the stock exh manifolds?dump pipes for the time being?, i only want it to be reliable right now, not aiming for huge power, just something so i dnt have to worry about the stock ceramic turbos going bye bye

changing dumps is a turbo off situation

better off doing it when you change the turbos. saves a LOT of dicking around later

[nsta]

Thanks mate, can the n1's use the stock dumps? heres the auction for the turbos, are these real N1 Turbos?p.s will these be ok with stock ecu for now?

If you dont mind me asking how much are you payign for these Turbos ? I was thinking why dont you just buy brand new ones ???

[nsta]

$1800 nz, which is roughly $1650ish aud

thanks

how much are these n1 r34 turbos brand new?

[MRGTR911]

I Paid for them brand New like $2,700 Off Memory. they were Genuine r34 N1 Turbos ..

I Would change Dump Pipes as well , Alot of labour taking off Turbos.. Up to you..

[Cooper]

What sort of dump pipes are people running with these turbo's? I already have a Do-Luck 3.5 inch exhaust and front pipes ready to go on but no dumps. I am about to make the swap to the N1's shortly.

Sorry for the hijack.

Cooper i am Running X ForceDump Pipes On Mine Its a Bolt on Pipe , I Aint having any problems Good flow And all ... And they go for good Prices ..

[nsta]

updated thread title, as it shouldve rear R34 not R32 gtr n1's

what was price of dump pipes?

the standard dump pipes are terrible. you really need to change them at the same time.

[nsta]

Thanks so i can still expect the car to run smoothly at low boost and running stock computer, and dumps with these n1's, as right now ive got hiflows on the gtr....but ceramic ones:(./....i dnt wnna blow my engine!

[Angus Smart]

i run the trust ones. thats the dunmps and front pipe in one (three piece)

very nice but anything is better than standard! tomei items look nice!

Cooper if your in new zealand your xforce dealer out there (who sells stuff on ebay under performance guru) has very very cheep xforce gtr dumps!

Does anyone know the diametre of the the pipe on the x-force dumps where the dump connects to the front pipe? And if possible the distance from centre to centre of the bolt holes on the same end? I need to know if the front pipes i have at home will bolt up to these dumps.

[R338OY]

I agree with everyone, standard dumps (entire exhaust actually) has crap flow. Chuck and replace!

If the front pipes fit the stock dumps i'd say you will be right! xforce ones are copys of hks dumps.

Hi, definetly replace the dumps but do not replace the manifolds. The turbo's are not big enough to worry about that and if anything aftermarket manifolds will give the turbo's more lag. Iam running these same turbo's in my r32 GTR with an R33 engine and Iam making 314.7rwkw on 20psi. With supporting mods like 550cc injectors/040 fuel pump/power fc/turbo back exhaust etc
