Hey, you know how everyone is saying, "this will be a great thread for someone who wants to build a turbo Z?"

 

Thats ME :D

 

YAY!!! thanks again everyone, the info is much appreciated. and now i am very jealous...of all of you :sour:

ENGINE: f54 block with stock turbo pistons, n42 head with NA cam. ARP hardware.

 

TURBO: T3 at 7psi with supra MKIII intercooler, boost at 2500rpms

 

FUEL: zxt 270cc injectors

 

ELECTRONICS: :( :( :( stock NA ECU with "tuned" NA afm

 

EXHAUST: 3inch DP with 2.5inch exhaust

 

HP: Lower then a stock NA l28!, or so it feels...

 

NOTE TO ALL: I just finished putting this together, its one of the many things Ive been doing to my Z while Ive been away... It pretty much runs like crap and I need MS, or at least a turbo ECU/wiring harness. Got one for sale? 707-252-6070, please let me know!

Chris and Big Phil, both of your cars are making tons of power with just a L28 without the diesel crank? Thats amazing! What is it about your builds that gives you all the power and torque? Custom cam grind? Bigger injectors? Big turbo with lots of boost?

 

It would certainly be cheaper to build a turbo engine with the stock 2.8L crank than to hunt down a diesel crank.....and if it makes that much power that way, then it makes me wonder why I'd bother looking for one....

L24 block, balanced and blueprinted, Aeris 9mm pistons

E-88 head, o-ringed, Racer Brown cam, Not sure about the valves or the springs but know that it was all replaced with high-end siht back from 1979-81.

MSD 6-T ignition, Mallory coil, MSD Super-conductor wires, Pertronix pick-up

Turbo Tom kit, Holley 660cfm carb ( was just rebuilt by Dan Davinci)

Water injection

I have put in a Centerforce Dual-friction clutch in the 4 speed. I don't have a lot of faith that the R180 rearend will stay together or the transmission for that matter with this thing being as stout as it is....( just more parts for me to change out)

I have not dyno'd the car but will when I get the cracked manifold fixed as well as a exhaust leak. It will be a while before this sees a dyno. I have a few other parts I want to change out. The car sat in a garage for about 15 years without being started or touched, I have been going through it slowly for the last 2 years and I think it will be about that long untill I am done with it completely.

 

Here s the thread on the car.... http://forums.hybridz.org/showthread.php?t=117481

Bottum end: Stock N block from 77 Z

ARP main/Rod/Head

2mm Metal Head Gasket 7:1 compression

Bone stock P90 head

60mm 240sx throttle body

N42 non-egr intake ported to TB

NGK plugs

Full boost hits @ around 3100-3300

15 PSI worked out to 280rwhp and 330rwtq around 60 degrees outside with 2.25 exhaust

20 PSI worked out to 308rwhp and 360rwtq around 95 degrees outside with no exhaust

25 PSI with the new meth kit running 100% Meth ???? Haven’t tuned yet???

The Heat really made a HUGE difference in power...the 280rwhp was using a 2.25 exhaust and the 308 had no exhaust but was hot outside!!! I wonder what the 308 would be if it was 60 degrees outside?

Going back to the dyno soon so I may play with a few things…Tune the car for the 25PSI on meth –or- Leave the car @ 20PSI and hit it with a Wet 75 shot. Still haven’t decided which way to go yet. I have 4 blocks in my garage so I might just have to see what the stock block will hold with a good tune.

Great thread. Anyone out there running a "blow-thru" or "draw-thru" carburated turbo set up on their L28?

 

Julius

 

 

 

yeah my lil brother who also has a 240z is doing a blow -thru carb set up should be done in a few weeks this is the stuff he has so far:

 

L28et long block

cliffford 6=8 4barrel intake manifold

t3/t4 turbo

holley 650 cfm double pumper modded for blow threw

greedy b.o.v. type rs

all he needs is a front mount ic waste gate and indution piping witch we might get this weekend

-engine= stock bottom end, 185km on the clock

 

-turbo= jy h-trim t04b compressor, t3 .82 stage 3 hotside

 

-Exhaust system - 3" as well as muffler bypass behind rear wheel

 

- How much boost- 21-23psi

 

-ECU= I ran the time in my sig with a nistuned z31 ecu/z32 maf, i dyno'd with an infiniti m30 ecu/z32 maf

 

- autospeed dc motor controller with an m15 and a m10 nozzle methanol setup.

 

-CC injectors - z31 ecu/440cc - latest setup = m30ecu/nippon denso injectors flow tested@670cc

 

-IC - dual grand national cores welded together with 2.5" piping both sides

 

-HP= 422hp on a mustang dyno @ 21-22psi

 

I should mention that I have a built cyl head, but I'm not sure on the specs.

 

I get about 5psi by 3k with max setting hitting around 4k.

 

In my opinion the L28ET is sufficient to run any zcar into the 10's with the earlier cars having very low 10sec et's available to them with very little work.
