r32 gtr --> twin turbo or single turbo and mods to block ?

[Bruizer]

any particular models ?

Imo you Don't need Carrillo rods or valves. If your oem valves are good they're fine to 800hp, safely. As for rods, there's no need for 1000hp+ rods when rods that are less than 1/2 the prices are good for 800hp like eagle, manly, spool (just to name a few) why build for 1000hp when you will safely run on 700-800hp parts with much less cost. No need to over I'll unless you have a good budget to go with. I went crazy cause my vehicles are paid off
Andy total bills with mortage still leaves me a good lump of cash at the end of te month. If you're building for 500hp but dont really have the large amount of cash, a built engine doesn't need to cost 20k.

Cp pistons (oem size so you had max cylinder wall strength), eagle rods, tomei gaskets, drop in cams Kirk greddy or tomei, n1 oil pump, oem water pump, 044 fuel pump, 720cc injectors and your good for 500whp. Less than $15k I'm sure, with machine shop labour. It wont be expensive Unless your engine is wrecked and you need parts. Most of us use these parts and they're fine. Eagle rods are some $600 and carrillo are $1000+. If you won't see a $50k+ build, the carillos are overkill. Really

Carillo rods, cp pistons, ferrera valves, arp bolts and nuts anywhere possible, all tomei gaskets. That should be a good engine

thanks to all answers , i think best choice for me , i will stick with the twins gt2860-5 , now what pistons / rods u guy's suggest ? seen some bundles on ebay / wiseco / eagle rods , cp pistion / manley rods ..... etc ... any suggestions ?

I had twin gt2860-5 and this year I'm switching to a single. The twins actually have some lag, there's a big issue with high boost causing turbo shuffle. A proper single will make more power then a twin setup and have the same or less lag. The single is more efficient, there's less chance for the air to become turbulent.

That's more an opinion than fact. There are many threads and forums out there that disagree.

and less mass, less overall inertia to evercome, less parts to fail, less complexity, etc.

I've certainly enjoyed my -5s, lots of fun.. But this year I'm going for about 550whp with a bw 7670 efr. It looks like it will spool as fast as the -5s without the compressor stall etc.. Btw Marius, make sure you do some reading about compressor stall and turbo shuffle so you know how to tune the car with those big twins..

70K!!! damn lol have a build thread?

I thought of that and realized I liked things better without one :S I don't want people to judge what choices I made. I'll post pics at some point.

Twin 2871's are laggy as hell on anything but a RB30. Your much better off checking out the new borg warner efr's if you want response and more than 600whp.But if you want to run twins I would avoid -10's. -5's have proven themselves to support 550+whp and are responsive.

Snatch up the 2530's in the for sale thread . They spool wick fast and should be able to support 550-600 with a built motor and good cams .

I wanna stay twin turbo if possible , already purchase hks manifolds with turbo elbows , i would like to run twin gt2871r ... It should hit the 600 whp pretty easy with the rest done up to the engine thats what my tunner said .. Will see now looking for pistons and rods to suport the power ? Any sugestions ?

HKS T04Z single, amazing power and relialble, good for 500-600whp
