Hey all im not really a turbo fan but i have seen some good power figures from turbo 202's and im thinking in a torana this would be fun for an every day driver

i no its been done b4 but what sorta engine/turbo/trans combo's are people running and what sort of power do they make? what needs to be looked at with the engine to keep it in one piece?

whats really got me interested is that i've heard of people using the wastegate to control boost, so one minute they have a virtually stock car then with a flick of a switch its goes like stink. how true is this?

im thinking of running engine on gas with the fuel prices atm.

all thoughts would be appreciated

cheers ryan

Well ryan i have been buying parts! as there is no way i am puting a rice motor in it, the JL is coming out and a blue.6 3.3 turbo is going in this is the parts
i used ,and machine work being carried out now.
BOTTEM END
Blue 3.3 block crank/rods all crack tested, line bored closed+honed main caps
Block :40 over+decked+groved o,ringed,deburred oilpassers+inlarged ,full stud kit
Crank:deburred/polished+knife edged counter waits,blanced, chamford oil passers
Rods:resized,deburred+polished machined for full floating pins,balanced .ARP bolts
pistons: custom aries full floating forged decomp/dished tops ,hastings Cr rings
JP,H/V oil pump,custom baffeled 7 litre sump+ big pick up+big arse oil cooler
Iven tie! turbo grind solid cam+crow lifters. straight cutts ,Cr manly push rods
Romaci race blancer, Y/T 18lb flywheel dowlled to the crank shalft new bolts
IgnitionMSD6al BTM boost timing master,two stage rev limiter, bluedizzy msd leeds
msd coil

Thats $4.000^^^ so far no turbo hopefully it wont handgrenade at 15=18 psi. i havent decidead on the head but the NEW YT12 port sounds nice!looking for 300 to 340 hp out of this motor not that much reaily? thats all u need in a street LJ

And those that want to no! the turbo is a garret T66/ custom manifolds yet to be made, by me and a mate using one of his lc toranas with a dummy block, this is going to be a draw thought set up using a holley660 ss D.P much the same as the pic,s above. i will post pics of us building the manifolds in the coming months

. The inlet manafold has a water jacket under the carbie with coolant circulating through it via the water pump heater outlets. Im guessing this is to help atomise fuel but was wondering what you guys think.

This stops the fuel from freezzing as it gets very cold on a draw though set up

as for your carbi probs yer the twin or even one 2inch su are good for the steet
a 2inch su will flow over 500cfm

Whats the deal with blow through VS suck through. What are the pros and cons? Can I use a SU or SD Stromberg as a blow through or does the whole carby Have to be pressurised

LCGTR! i think that you can blow through a SU or CD stomberg
It is some thing that i my self havent tryed as yet but i cant see a
prob! you need to pressurize the float bowl , at 2 two 3 psi more
than the manifold pressure .IE" if your turbo is runing say up to
10 psi max , then you need 12 to 13 psi fuel presure

using the right rising rate fuel reg there are several ways to do this ,with out boxing the carbi in. and it relates to all carbies with the float bowl venting to atmosphere .
Most go for a holley to blow through it still need some mods though
floats must not crush in under boost so you fill them with a special foam
then solder up the hole you made in it . then the throttle sharfts need grooving
for o,rings , you remove the power valve in the holleys and mod the fuel
Sircuit for enrichment at hi boost levels
The plenum you design should include a blow off plate above the carbi
in case of back fire! yer there is a bit to it but it looks alot better with out that big
box ! THERE THE PROS

A mate recently fitted and made from scratch, a DRAW through SU set up bigass rayjay turbo to his ricer! run about parts trolly ,,...its a 2.6 astron scorpion .and using a singel 175 su it runs
Low 13 seconds its faster than his CRS type" super charged torana but he dosnt like to tell to many people that!,,, he,he" Its bloody fast for $500 all up fitted

THATS THE CONS

What if you vent the boost controller gasses into the exhaust hehe.... then have a spark plug at the end of the exhaust.
Whenever you hit high boost you'll be shooting flames out the zorst..

...maybe

mate if he has it on gas then i dont think it will work but on fuel and the right setup then yeah u can get around 3 to 4 foot flames out the back...

the ultimate carby turbo setup would be blow through with 3x webbers on a normal webber manifold.
now between the carbs and the manifold run a backing plate and basically build a plenum around the 3 carbs.

its a very similar setup to the rb26 without the injection

i have been talking to a guy that realy knows his turbo setups
old or new he his a smart little bugger when it comes to some of these questions
he tells me that you can NOT blow through a SU OR CD! as i said you may above! as the slides in them
have cut ventures on the inlet side, plus he made a fuss about them being used
as draw through , not good as the needle/ seat wear very fast drawing the needle down the side of the seat ,then thay start to run to rich.

i was allso saying above that i was going to build turbo manifolds in the next few month , well i got some garret ones cheap off a freind so no need to stuff around
now. making them ,,

I have a blow through set up using an HIF 44 SU (1.75inch) on my Mini. MG Metro Turbos were sold with this set up, using an SU and a garret T3. Difference between the "turbo" SU and the NA SU is the throttle spindles are sealed but not much else. I have a pic but can't find it.

I remember there was a lad called turbotrana (or somethin like that) who had a pretty sweet efi turbo 202 setup in a sleeper green lh/lx a year or two back. From memory he made over 500rwhp. Does anyone else know of or remember this car?
