Single twin best

[bellis_GTR]

Los of respect tot he single turbo guys. And I am VERY wel versed on the ins and outs of both setups. But I still just cant deny I love my twin set up.

Speeddm! Those look amazing! Can you please share details on those beautiful pieces of work!

[NismoS-tune]

yeah i know over there u guyz can make CRAZY money!!! here in quebec aint like that la !!

yeah i wanna go wit that! 100% sure wich turbo kit u tell me to go wit tho

t51r or t04z

T51R BB SPL go the works. I built with 15k and stopped at -5s cause I couldn't afford to support a way larger size of turbo like those

I love my T88, Carrol Shelby said it best in the '80s when the turbo 2.2 Dodges were all the rage....."if you are suffering from turbo lag then you ain't driving it right".

I have done some bansia runs on some of the windy secondary roads here in BC and I have no lag whatsoever if I keep the revs above 4500. For an old school knuckle dragger of a turbo, it stays on boil without much effort. You just have to have the balls to squeeze that throttle just a little more at the APEX because you get ALOT with only a little push. Learning to hold her back is a sure fire way to live longer.

stop loving on HKS !!! there is like 3 turbo companie out here that are cheaper and more avalible that will beat the HKS

full-race manifold or 6 Boost / even a custom manifold !

- precision 6262 and up if you want 500+
- BW EFR
- Garret GTX

Dragon Humper, that's how you drive a GTS-R (race version of RB20DET). Basically drop down a gear to keep revs up and engine in powerband.

Looks like Tomei manifolds/outlets and smallish turbos, maybe -5s? The downpipe is maybe greddy, hks or nismo? I recognize the mani/outlets as I have the upgraded version of those

[Speeddm]

Yup Tomie and -5 combo ceramic coated. Not to mention my own custom Copper gaskets. The down pipe was left over from Super-Dudes first build I did back in winter 08. He would have a better idea which one that is.

[bellis_GTR]

Thanks for the info. They look great man. Can I ask why you choose the non divided outlet? Is there any gains with a divided outlet? I know it gives an awesome sound when the wastegate opens but thats all I know lol...

[Speeddm]

You know what i have to be honist about how these parts came about. We started Super_Dudes V1 build with this setup plus the Cosworth ported head, Nur bottom end, CF driveshaft +++++. We got talking one night and he mentioned to me that he was going to run the twins then go single in a year. So I told him it would be far cheeper for my labour to go single now due to the amount of work overlap and paying for the work twice. So we found the GT4088R setup from a GTRC member and bought it. The setup worked alright even though I wasnt to happy with the compnents we still made 587whp on pump. Anyways the -5/Tomie combo was left all NIB i took that as partial payment. The combo of items was desided after many conversations with Eric Hsu and XS Engineering. Im sure Super_Dude could expand on that.

Now the car is going RB30 and EFR turbo so there will be a FS thread comng in the next few weeks. We will keep you all posted.

So really, he paid for some kind of work more than once. What's your rates like? $150/hr? $200? eek expensive.

Which EFR turbo? 91mm? 1000hp? Cause I'd hope it'd be better than the previous 600+hp one.

[DougTaylor]

I've decided to replace my -5 setup with a BW EFR 7670. I've already got a top mount single manifold with WG but the EFR can come with an internal WG and recirc BOV. The EFR that comes without an internal WG only has a 1.05 a/r, while the ones with an internal WG have .83 or .92 a/r. So, I have a couple of questions - any comments on the different a/r's vs spool rates with the EFR, any comments internal vs external WG, and does anyone know if any dynos of the 7670 on the rb26?

Thanks

NismoS if you have no idea what you are talking about. You probably should just shut up so you don't look stupid. Building a car with a 520whp twin setup planing to tear it down to build 600whp in 12 months isnt the smartest way to build a car or spent your money. So we made the jump at once. You have no idea what was done to the car over the 11 month build so zip it.

Was just trying to understand why 580whp wasn't enough and what was reused/replaced. Is there a build thread somewhere I could check out? Just curious how much work it would be if someone else wanted to do the same. Is all I do like your work though, so I didn't mean to hate. I'm really jealous, I swear. I'd just like to see what's all being done sir. I'm considering upgrading myself but would like to see what all is involved. I'm pretty useless with a wrench so I wanted to get some insight if someone would be talking 20k build or 80k build kinda thing.

Edit: Reading a text sometimes may trigger incorrect feelings so blame my wording maybe, I should not post at 12am after a days of work when I'm up at 530am. hah sorry, yes I dont' know what I'm taking about which is why I pay others to do the work I guess.

[Black BNR32]

7670 stuff can be seen on nasioc under the Perrin's BW testing thread.

[curtisgoodman]

Haven't tried or been in a big single but i only have one complaint about the twin -5's im rockin... shuffle i have yet to get a properly divided twin turbo pipe to solve it but -5's are more then enough when built with proper supporting mods to scare the sh*t outta you power and response wise...
