I can't find him.

Doesn't seem to be in Tasmania.

PM 'Dodgeman' he'll know for sure.

I don't know his name but there was a guy running up to 30 psi boost on his suck through set up. He's in Tasmania, really cool set up - it was a 2dr 1000.

I'll have a look.

whoa!!!!!!!

that is a good read!!!!

it's a testiment to the strength and durability of the A-SERIES engine! even running upto 30psi of boost!

Is it still running does anyone know??? wouldn't mind knowing more on the methanol/water injection setup that he's running,

anyone have any thoughts on that?

Any other turbo setups???? Come on everyone, don't spare the details!!!!!

the main problem with using a carby (i used a 32/36) is after a while under boost the carby will go lean

i did although have the stock dizzy regraphed it cost be about 300, not using it anymore if anyone wants to make an offer on it aswell. having it regraphed is better than just locking it because you still do want some vacum advance it was setup for 10 degrees vacuum advance which stops it pinging at full boost


Hey Frank, I'll share a few pearls here....

I found with the blower that the 32/36 ran lean after a while at full throttle as well. the problem is that most of them only have a 1.5mm float valbve orifice filling the carby bowl, but you have a 130 & a 175 jet (or something like that) sucking it dry, so you just run out of fuel. I successfully redrilled it to 2.5mm- it still seals fine & provides plenty of juice.

The easiest way or re-graphing your dizzy for tubo/blown is to take it apart, put a small dollop of weld on the end of the slots for the weights. This reduces the total advance. then you gradually lighten the weights untill you get a slower progression to full advance.

you get good at taking dizzy's apart!!

sorry if this is hijacking the thread, but...

If i have a JTS ignition system (electonic distributor not running vacuum advance) will i have any troubles with it when i turbo the engine?

Also, if i was only looking at a low psi boost setup (7psi max say) do you think i would have troubles with the needle and seat in my 32/36?

can't help you with the ignition, but you will definatley have trouble with your needle & seat. dead easy to drill it out though. Also, invest $40 or so in jets & air correctors from Alfa 1750 on ebay.

Did a Google search and this site/thread came up so I thought I would show you my setup on an L18 in a Datsun 1600. Have done a lot of work and hours reading and researching to get this setup to run right with great success.
Cheers guys.
