I just found a procharger that will fit...looks pretty good.
Before I installed a TT383 into my 240 Z, I obtained brochures and measurements for their carbed 350 kit. I determined that there would be interference between the strut tower and the rear portion of the centrifugal supercharger housing. In addition, a bubble would have to be fabricated into the hood to provide clearance for the upper portion of the housing.
However, the reverse rotation Vortech unit for the Corvette LT4 setup places the housing closer to the center of the engine and lower into the bay. I almost ordered this kit but then a friend gave me his turbos to use.
Hope this helps.

Bring it on inliner boy
....provided of course that the thing doesn't put a hole in the piston, or block...
Hmm....I do believe you are right, Tim..... 525 does have quite a self-proclaimed history of metallic Z car carnage.
I won't join in this fray, I'll just be content to stir the pot.

Just for accuracy' date=' I have the LT, not LS....but I would spank that little air blower anyways

That's funny... that's just about the same thing this Nova owner said
"Good one", 525!

Sure wish I could join this debate about V8 vs. Turbo. But but since I have a TT383 Chevy in my 72 Z, I won't take sides. Oh well, it must make my Z twice as fast.

I'm using a MSD 6BTM in my 72 240Z with TT383 Chevy. The btm retards ignition timing which may be adjusted with a rotary dial for 1-3 degrees per psi of boost. Total retard is 20 degrees depending on the adjustment and the amount of boost generated.
I run 10 to 15 psi boost and retard 3 degrees per psi. When the engine reaches 7 psi, timing is retarded by 20 degrees. I'm losing power at launch but the topend is awesome.
If you run 10 psi on your engine and you only adjust for 1 degree of retard then your timing will retard only 10 total degrees, and etc.
I would not run my carburated blow-through turbo engine without the btm.

I'm using a TH400 in my 72 and TT383 Chevy. I did not have to do any hammering in the trans tunnel but then I am using a full reverse valve body. I only cut out the ears in the tunnel for more clearance. The trans mount is a JTR mount and you just bolt it to the underside of the car in whatever position you want the trans to be installed. Good luck with your project!!

"Quarter Mile: 12.68 s @ 112 mph-> 0-60: 4.9 s"
I think that time is for the TT Rotor engine, not the TT SBC, because I'm running 116 mph in the 1/8 mile with my TT 383 SBC.
I'm thinking that the low placement of the turbos will interfere with the Z's steering rack and linkage, because I tried that location myself before settling on my current set-up. But it looks nice in the RX7.

Mike,
That's moving.
I think better tires, alone, will put you into the 10's. Better do it soon before it gets too hot in the summer!! But then there's always Fall and Winter. I'm impressed.Hanns

That's a good trans combo. I'm looking forward to seeing what times you turn with your TT set-up.

If you are refering to the cylindrical object in the upper left section of the top photo it is a solenoid to activate a transmission brake on an automatic trans. One wire goes to ground; the other to power via a momentary switch. When activated, the unit locks 1st and reverse gears allowing the engine to be revved to the limit of the torque converter. Then when the switch is released the gears instantaneously disengage and allow high rpm launch for drag-racing. Hope this explains it!!

What's going on?

The MSD 6AL-BTM has a rotary dial that allows 1,2,3, degrees of retard per lb of boost, for a total of 20 degrees retard. Actually, if the BTM is turned one increment further where 4 would be, if it were so marked, it will retard by 4 degrees ( MSD denies this ). So in effect, all this unit does is vary the speed with which you activate ignition retard.
With no other changes, if I retard by 4 degrees(max boost 15psi) the TT383 Chevy Z runs 113 mph in the 1/8th mile. If I retard by 3, it runs consistent 116 mph ( in the 1/8th not 1/4 mile ). Retarded ignition timing does hurt power but saves parts.
The MSD unit is powerfull, too. After my last engine rebuild the engine started quite well but ran rough. It also seemed to be down on power so I tried different timing curves that had proven successful in the past. It still ran rough so I checked the usual culprits. To my surprise I discovered that I had neglected to hook up the #s 2,4,6,8, plug wires to the sparkplugs.
The engine started but ran rough on half of the V8's cylinders.Hanns

Who was this fellow member?

Dan,
It's about time someone recognized your creativity.
Your Z definitely has "a few toppings for some extra flavor". The photos, including the cover page, were nicely done to show all the time and effort you invested in your project.
I was very much impressed with your Z when I first saw it at Rio Vista. The color and workmanship is outstanding. Congratulations and may this just be the beginning.

I have never heard of a Currie 9 Plus third member, and I thought a Ford 9" with the weight of the Z was nearly indestructable?
Jack,
The Currie 9" Plus is just a heavy duty Nodular Iron ring & pinion housing with extra structural strengthening ribs and pinion support. The amount of torque that it is subjected to and the weight of the vehicle determines its longevity. Also, the age and general condition of the 9" is a factor in how long it survives. The lighter weight of the Z helps but My 9" was old and swap-meet quality. You would probably have better luck with a good condition stock 9" but it will not handle constant 700/800 ft lbs of torque drag-race starts.
Many major drive-train specialists, Strange, Currie, etc., sell their own heavy duty R/P housings at reasonable prices. Hope this helps.

Hanns what diff are you running
I have a narrowed 9" Ford. Once I got the Currie 9 Plus third member I have'nt worried about that part of the Z. A few drag-strip runs burned up the carrier bearing and clutches of the stock 9". According to Currie, the stock 9" is good for only 350 rear-wheel hp.
I'm retired-it's time to play ( the faster the better )!!!

I hope to hit 145mph in the 1/4 mile with 16 to 18 pounds of boost on a 350 or 383 cid.
I have run 137 mph in the quarter mile with my TT383 Chevy Z at 10 PSI boost and 116 mph with 15 PSI in the 1/8th mile ( that equates close to 145 mph in the 1/4 ). I can now generate 25 PSI but I have no competition license and dont want to get kicked off the track again.
With 29" tall tires, 4.11 gears, TH400-3800 stall, 137mph showed 6000 RPM at finish line. That's not theoretical thats eye-balling the tach; my set-up,anyway.

I'm finishing up the exhaust and I'm waiting to take delivery of some lower compression heads so I don't melt those pistons.
Ben,
Glad to hear there is progress with your exhaust system. You wont regret changing cylinder heads because you will be able to run higher boost I found this to be true since my engine is running better with the lower compression than before. Keep working at it.

Has anyone here installed a TH400 into a Z? If so' date=' did you have to modify the stock trans tunnel?[/quote']
I'm using a TH 400 and TT383 Chevy in my 72 Z.
The fit depends on how far back you mount the trans in the tunnel because at some point the Bellhousing will interfere with the firewall. However, that point is generally not reached because the rear mounted distributor on a Chevy will be the first obstacle to the firewall. I cut out two small protrusions on either side of the trans-tunnel, not due to interference but just because I wanted more clearance. If you do have clearance problems, use a hammer unless its a show car.
Good luckHanns

Beautiful, Hanns - I'd love to see it in person some day. If I get out west, I hope to look you up!
Pete,
I appreciate your comments. If you do look me up I might have to give you a ride in the Z you'll never forget.

Hanns, don't worry about trying to catch up with the new technology. Your car is a classic example that old school can and still works great.
Thanks for the nice comments. In part, that's what makes the work worthwhile. The other part, of course, is getting nailed into the seat when you hit the gas.
I will probably be at the national convention in June. See you then,Hanns

Hi again Turbo Meister, I personally feel that your car should of earned quite a few award for the dedication, creativity and most of all for the inspiration that you provide us all with.
Thanks for the kind words. My goal is to advise and inform anyone interested in building a Z like mine. Unfortunately, I'm better versed in "Old School" technology as opposed to "New Tech". But I have learned a few things the hard way especially since I had to do much on my own. I'm still learning, myself, and may still catch-up with the "Today" crowd.

Thanks for the comment. I know you left a little early, but man that LS1 must have been flying to get back so soon. 8)It was nice to see everyone but where are all of the other hybridz members??????????Yes, I expected more members but I guess things happen!!!

I can't remember jokes but I have one for you since you are the Hybrid Z Joke Meister.
Did you hear about the dyslexic, agnostic, insomniac?
