HKS 2835 twins?
Anybody have any experience with using these twins on an RX7? Guilly just made 780 HP with a stock block Supra no NOS using them. They seem like they would make some good HP on an RX7. The Kit seems pretty expensive though around 8000 bucks. I wonder what kinda lag they would have on an RX7.
|
Lag? please.....they are ball bearing turbos, they are supposed to spool up fast. I think it'll be an awesome set up on a RX-7 :)
|
Well usually turbos that can support 800+ HP tend to have some lag.
|
On the rx-7 the 2035's would not be laggy at all!
Actually on the Rotary the 3037's would be the better set-up and the more often used twins to make serious power due to the larger exhaust wheel than the smaller ones on the 2035's. Delta_Rotary!----How much boost was Guilly running? crispeed 87TII 9.20@150mph T-72@35psi 650RWHP/520RWTQ |
Guilly was running 29lbs with a shot of NOS.
On the Supra the HKS twins are pretty laggy. |
screw twins...a proper sized Single turbo is much better..make it simple:
1 motor 1 turbo 1 fuel managment system |
On the Supra it's not that laggy when you have an auto trans with a 3000rpm stall!:)
I ran 10.40@130mph in a 94 Supra with a complete stock block and head! I was able to boost 14psi before launch!:) The I/C hose came off just before the traps so I guess it could have been a better run. crispeed 87TII 9.20@150mph |

I'm trying to find a single turbo that would support 40 psi at 10,000rpm without that much lag! Have not been able to find one with the right compressor map to support that! Now if two small ones are put together!:) crispeed 87TII 9.20@150mph |
Guilly made 834HP on NOS @ 29 psi. He was making 541HP with only 14 psi. How much HP do you think the 2835 and the 3037's would make on an RX7 cris?

2835R
the shop i go to is putting them on a b p. should have some #'s by thur or fri.
|
I will tell you very soon who much power two T66 turbos mated to a "full" Peripheral Port 13B will make with 30psi boost very soon:D
Who needs NOS, when you make peak power at 10000rpm:D |
Does anyone know where you could get a decent price on these turbos? Most places I've seen them are @ Supra shops and they are very expensive. I might have to call up Jason and ask him how much he could get them for. Sounds like a new wave of RX7s are in the process, or are thinking of strapping these puppies on.
|
I just realized that the cover car for the September Issue of Turbo has the 2835's. Too bad the car hasn't been broken in they didnt have any dyno numbers.
|
what about 2 apex rx-6 bb turbos??? one of them is good for 450hp and they are using 2 of them on the r34 veilside skyline making 1100hp... i was just looking at them and u can get just the turbo for 1250. but that is just the turbo nothing else.. how much would it cost for the rest of the "stuff" you need to hook up twins??
|
i just finished my own version of a twin kit, un fortunately i was off on the turbine calculations and am getting quite a bit of backpressure. this will be taken care of in the next couple of weeks. i have a B P motor and Haltech and this is my street car this is a "test bed" for my race car and i am just playin around with different setups~:D my pic is too big to post so if anyone wants to see the set up let me know

sokudo
can get turbins front pipes and manifold for about $6000. the shop got 580hp at like 18psi. japanese tuner stay below 600hp with factory eccentric shaft. that why such low boost.

So there is a twin "kit" for the 3rd gen with downpipe, manifold, etc. or not?
|
M2 offers a set of ball bearing twins for 3k. Who makes thier set up?

yes
top fuel makes that is a machined 3 pc shaft for about $3000.
|
FEED makes the manifold for the twin parallel set up. The manifold is made for the GT flanges. From what i know the cover car with the twin 2835 has never been dyno'ed. They were having prblems with tuning.
I think that RE Amemiya made a limited run of a twin manifold to support GReddy turbos. |

Originally posted by sokudo top fuel makes that is a machined 3 pc shaft for about $3000. Come to think of it there are 700+RWHP13B's that are not having any problems either! crispeed 87TII 9.20@150mph |
Cris how much do you think the manifold would cost from South Florida?
|
Is it possible to make a streetable 700+RWHP 13B? The Supra guys can do it on the stock bottom end. Can we do it with our cars as well? I'm guessing we'd need at least a bridge port...

XS manifold
I saw an ad in turbomag afew months ago for XS. There was a pic of a manifold for FDs for parallel twins that they make.
