GTR turbo low mount upgrade.. which turbos?

[KBNR32]

Replacing my turbo's on my GTR in the next few months.

What are the best low mount.. bolt on.. GTR turbo's. Some say HKS.. but which ones... some say Trust... i want some feedback and reasons why? Thanks

The "best" turbo will depend on what application you want it for. You want response, top end power, or what?

It has been covered fairly well in the past. I found these threads to be of the most help. Happy reading.

i would go for a pair of T51Z's

for a great balance of response, mid range and top end balance.

price is also very competitive.

hks 2530s for response and power (same response as factory )

hks 2540s for the extra power but lack the response of 30's

depends on the use of the car

cheers

how much are the 2530's.... anyone know where u can get at a decent price?

[400kwgtr]

theres a brand new set of r34 n1s with ball bearings and steel wheels on ebay usa at the moment, if i had the money i would buy those.

[doridori32]

2530's are laggy on the stock exhaust manifold and stock dump pipes.

spool around 3500rpm which i say it a lag box.

[ferni]

If you want a little more response than 2530's, try GT-SS

Hey anyone know where to get good priced low mount aftermarket manifolds, I have 2530's and might be interested in getting some better flowing manifolds.

Also, opinions on the best dump pipes, I have seen Trust jobs with the collector for turbine and wastegate down quite a way. I also like the Tomei dump design, which I had on my SR, worked wuite nicely.. less collection resistance.. Opinions appreciated.,.

2530's are good street turbo's but also don't look past the N1's even though there are many version . It's right in saying that the stock dumps are very restrictive , my 2530's will be coming off soon to make way for some nice aftermarket dumps atleast and maybe a change in manifolds .

I'd also be interested in ppl's opinions on what the best dump pipe setup is at the moment ? .

I'm using HKS dump pipes and front pipes...but i cant tell you how good they are as i put everything on in 1 go...they seen to be in a really good quality though

[7heavn]

how big are the hks front pipes?.

[Blitz]

Im using the Apexi GT spec front pipes and I found the quality to be excellent. Stainless 3 inch pipes at a fraction of the cost of HKS. $693 from memory from UAS

[Jago]

if the stock manufolds are restrictive why don't you just modify them?

If that's too much of a problem, then just buy some new aftermarket ones.

As far as manifolds go, I would be interested to see some dyno results for a car that has upgraded from factory manifolds to HKS/ported items.

I wasnt aware that the factory items posed any serious restriction

[MSRB26]

I am running R34 N1's with the .64 ex housing, still using stock manifolds and dumps making 302.9kw at 17psi. Will be putting the car back on the dyno soon to wind up the boost a bit more and see how much further we can go

I would recomend them to anyone wanting a good street turbo setup at a reasonable price. Other than that i know of a few GTR's getting around with Trust T517z's making a comfortable 330kw with stock internals.
