Well the 7 goes to KD tomorrow for the single turbo install. I am very excited about getting it all done. Its been months in the planning and a long list of Parts showing up everyday up to now. Here is what I am doing. Feel free to add any suggestions. The car is modded now but adding the single turbo and additional parts. Listing everything I have thats already on and what I have going on this week at KDR. Goin to run 15-16 psi max until I get a ported motor and some other upgrades.

only thing i would do is get a racing beat six puck sprung disk for your act pressure plate. you will annhilate that street/strip disk very fast with a gt35/40 @ 1kg/cm^2

everything else looks damn good. maybe another fuel pump in line

 

Hey thanks Vosko. I thought about the clutch as well. I want it to be somewhat smooth engagement. How do the sprung puck clutches feel? How well do they hold?

 

i have a six puck racing beat in mine. the engagement is instant. once you get used to it. its not bad at all. i have been beating the crap out of mine and its never slipped once. even starting in 2nd gear because i broke first gear. the clutch doesn't slip

 

Thanks. I may order one and have it delivered to KD. 144 buck is worth not having the hassle of a fried clutch. You never know where its goin to let loose. And you can count on it being as far from home as possible. I had my last ACT let go in Maryland on 95 the day before thanksgiving 2 years ago. Had a bad disc that lasted 2 weeks. That was a very expensive clutch. Had to rent a car and pay a dealer to install a new one. Nightmare. That was back when the car was a daily driver. Thanks for the tip.

 

well nocab72 and silver93tt both killed street/strips fast...... i assume you will do the same

 

I am getting my T78 and new BNR Race ported motor installed this month as well. I know Vosko runs the T78. My clutch is the Spec Stage 3 sprung 4 puck clutch from BNR and Racing Beat Steel flywheel. Do you think it will hold up to very much boost. It did fine with my twins but I am unsure about the T78 setup. I was going to go GT35/40 as well, I love Kyle's car but I like the price and power of the T78 more. What do you think? My car is apart right now so I could easily change it if I wanted to.

 

ive had the T78 twice and i can say the GT35/40 is a better overall pick for my street/strip driving.. The GT35/40 spools much faster than the T78 while still giving me great boost gains up high.. dollar for dollar i think the GT35/40 is much better than the mitsubishi T78... ok lets take Jason's prices (which are pretty competive and not near retail)

Greddy T78
$3399
Mitsubishi T78
-does not fit perfect needs j-spec manifold or dent your downpipe.
-wastegate is routed to atmosphere
-mild steel downpipe


Garrett 35/40
$3900
Garrett 35/40
-will fit perfect on U.S. RX7's.
-wastegate is rerouted with a flex-pipe to downpipe
-downpipe is stainless steel
-the compressor housing is polished
-the downpipe is jet-coated
-most of all the GT35/40 is a true dual ball-bearing design giving fast response
-water cooled bearings for increase cooling
-plus customer support through RX7-store/a-spec is much better than calling greddy (installation questions,missing parts,damage,etc..)

so for $500 more for the GT35/40 you get the all the differences listed above

remember im using RX7 store pricing...normal retail on the Greddy T-78 is $4500..so at Retail level the GT35/40 blows the T-78 price wise

considering the GT35/40 is a fairly new kit for the RX7 and not many people have it compared to the Greddy/HKS/Blitz/Apexi ... im impressed to see many people already putting down over 400rwhp while having great spool-up. overall i think the GT35/40 is the best overall turbo kit per dollar

either way both turbo kits work well on RX7's.. im just happy to see more single turbo RX7's on the street every day!

 

T-78 all the way. It eats GT35/40's for lunch

I also use the Spec 4 puck clutch and it holds up well. Good clutch for the street.

Any day baby, any day

GT35/40 is what I run, you can take that T78 lagmaster all the way home.

 

Lagmaster That's great! But I think there is only one king of lag on a stock ported motor.

HKS T51 KIA Kit

Short oversized manifold, undivided turbine housing. It sure looks pretty though

 

You really are loco.

 

And exactly WHO's T78 ate WHO's GT35/40? I certainly don't remember anything like that here locally!

You have to keep your car running to eat others lunches...

K

 

I agree that is the lagmaster.

 

not really just insane, there is a difference you know.

 

I would upgrade the fuel pump, change the clutch disk, and buy a datalogic.

 

GOD u guys pay alot for GT series turbo`s.

I can get a GT35/40 for 2k AUS - which is 1k US....
Or are u talking about kits? if so, wat is in the kits??

Cheers
ben

 

where in australia??

 

The $3900 US is for a kit. Includes turbo, manifold, wastegate, downpipe (ceramic coated and gate plumbed into downpipe), and all fittings/lines. Pretty sure it comes with an air filter as well?

Correct me if I'm wrong.

RX-TION...that really pisses me off. I bought my GT3540 last January for $3k AUD, which at the time was about $1800 USD!!!

Damn that sucks...

 

hey .. brad .. thanks again.

 

poor ihor is still banned i think....he could give his 2 cents

yes he went to act 6 puck, and you might want to think about your diff....seems he started breaking everything once he got that turbo

 

i started breaking everything once i actually got to drive my car

 

Wont be long now! Everything arrived at KDR and is being installed. Next week will be dyno tuning and finally on the road! I will post a dyno sheet.

 

ZoomZoom, what a great (only a few days late) Xmas present to yourself! Be careful driving that beast home!!!

I have driven Jason's 4-pucked T78. The 4 puck isn't that bad at all. I have no fears about putting in a 6-puck (in terms of driveability) after driving the 4-puck. Reverse is kinda funny, but manageable.

About the T78: After driving and tuning Rmagic's and Jason's car...properly tuned and on a properly prepared motor these turbos ROCK. But that is true for any turbo/motor combination. The engine is the foundation, and the turbo builds on that. Kyle's car is A BEAST! Time for a new license plate, Nocab!

To see T78s and GT35/40 Rx-7s running rampant on the outerbelts here is an amazing sight.
