Single turbo conversion ..

[cschepp]

Because here in Ontario cops are dicks! If you have any modifications done to your car there could be grounds for impound and obviously get dropped by your insurance. Likeliness of something like this happening is unlikely but by law they can do it

[coston]

I've never had a problem with that. They only seem to care about emissions and headlights. Never really complain about engine mods..

[Dragon Humper]

it completely changes how much power you gain or even lose for that matter each psi you change. there is no standard every psi i up i gain x whp. rule of thumb is 10whp per psi tho. although that can change greatly

Werd.........

Once my T88 is in the thick of the effeciency island (with my combo of parts that starts at about 17psi) I am picking up about 25hp per pound of boost till about 24ish, then it starts to trail off. For those of you who doubt, I pick up about 18mph in the quarter going from 1.1 to 1.5 bar of puff. So to push it to the limit (1.7 bar) I pick up about 300hp over and above the 500ish it puts out at 1bar.

Results vary tremendously based on cams, mannys, turbo(s), exhaust and above all else, how much ignition timing you have the cahones to run.

Only problems the cops really had with me was me modifying the speed limit

[r33_gtst]

Cops care about catalytic converters, legal exhausts, emissions and headlights.
Not wanting to go to a single turbo set up to avoid police hassle is a little silly.
Unless you got a jet engine under the hood, you should be fine.
And legally they can't ask you to pop the hood. They can threaten to impound or give you some HTA nonsense but having a nice engine bay is the least of their worries. Nothing in the hta that says you can't upgrade anything on your car.
As long as it passes emissions, is insured and played your good to go

this thread is about big single not about ontario police!

[LuckyGTR]

iam going on the dyno from now to 2 weeks 100% sure ,
engine is in r34 tranny is in too , not much work left to do , i will share my stats soon

[Daryl @ RightDrive]

I would say that single set ups would cost more in the end due to the amount of other parts you have to buy, such as manifold, downpipe etc.
There is not such thing as a responsive single that makes big power. Going with a twin setup that is set up for response is the best bet. Look at Mines R34 for reference. That car is crazy fast, and running twin HKS 2530s

Single turbo setups are cheaper

Ah really? So I'm starting out with an oem TT setup, already have the mani's, plumbing etc and all i need are. . .say -5's. . .

Find me a quality turbo kit. . .manifold, turbo, downpipe, water/oil lines, intake piping, filter, gaskets, wastegate(s), clamps and all other necessary hardware cheaper than the 2860's. . .

lighter

Now now. . .OP wanted the facts. . .what's the weight of the complete oem setup? Weight of the complete single setup? Difference?

same response or better

Very hard to beat the factory TT setup response with a single. . .unless you went with a small GT30. . .then what would have been th point?

There aren't many big power twin cars out there like there are big singles.

Do some reading on other Skyline Forums. . .The Europeans and Aussies love their twins and have a lot of info on almost every option out there. . .

Even neons and cobalts have single turbos man.

Because every auto manufacturer would love to put 2 turbos on a small displacement 4 cylinder. . .

I am clueless

Quoted for truth. . .

Cortexx, that setup you're looking at is a very good option for your goals. I've been pondering the 7670 in a 0.92 TS setup. . .would be pretty fun. . .There are a few forums overseas that are pitting the EFR turbos directly up against Garrett's new GTX line-up. . .very interesting results. . .Phone up Full-Race and talk to Geoff about what you're looking for in your car. . .very patient and knowledgeable guy. . .

Good luck getting an EFR this season though. . .every shop I've contacted has none and they're backed up 4-8 months. . .

+1 on twins. . .that R34 has a different final drive as well though. . .cheating a little bit. . .

Give this a good read, lots of good material in here. . .

your opinions are so skewed its completly irrelevant. you cant compare a "quality turbo kit (big single)" to a stock set up with -5s that makes no sense at all. also we arent comparing the response of a stock twin set up to a t88 we are comparing similar powered cars. no **** a stock 300whp rb26 will spool faster than a 700awhp t88. come on common sense.

There is not such thing as a responsive single that makes big power.

There's a chart showing response vs hp with different size HKS turbo's -

I think part of what makes Mines R34GTR responsive is the R33GTR V-spec 4.111:1 diffheads (shorter gearing). It's becoming a common mod outside Japan on R34GTR and on R32GTR they fit R34GTR gearbox (was said that can buy conversion kits in Japan with I think was single piece carbon propshaft, etc) with R32GTR 4.111:1 diffheads and similar spec engine to Mines R34GTR.

Ok but if using the hks 2530's compared to a t88 don't you think you would notice some serious lag time?

You are comparing a 500hp twin setup to a 800hp single setup. Of course there is a ton of lag on the t88.

And you know what, dudes with 500hp twin setups are spooling a whole 500 rpm before me, whooptie-friggin-doo. About the only twin setup I would even remotely entertain is the full N1 setup (mannies and turbos, killer response) for ligning quick spool and 600hp. Everything else lags enough that my T88 starts to look good.

Well the borg warner EFR turbo looks like an interesting project , wont be this year though , new engine in this winter coming however who knows what idle hands will install with the new motor
