1320ft's 2.3L Strip Warrior, Cage is in PG8

[1320ft]

The other question is; In my sitchuation is the dual runner manifold going to be any benefit over the std unit? I just need to shove as much fuel and air in the combustion chamber, as fast as poss.

When I can afford it, I will go for one of the hypertune units, but for now, one of these will do.

[thrash]

from what i've heard (i wouldn't rely on this without some level of testing shown), the cyclone intakes with the split runners and butterflies were designed by mitsu to boost midrange performance over the standard manifold.. it would possibly be more of a restriction up top than the n/a manifold.. if all you're doing is drag, you're playing in the upper rev range only, and so the cyclone intake will net you a loss of some peak hp perhaps.

This is all theory and it makes sense, but i have not seen any tests such as back to back dyno runs etc to prove it or otherwise.

Just had a look on 4Gtuner, the go appears to be the NA 4 runner.

If you'r not going for an aftermarket mani, then the N/A ,maby with a bigger plenum, would do fine for drag.
Since you will have to move the inlet you might as well enlarge the plenum. Not that much extra work...

If you want the absolute best IM and you have the $$ then you have to have a HYPERTUNE manifold and TB
Greg aka WANTSOM has one on his track car as they now make them for our RWD application
NOTE BUSCHUR RACEING have flow tested heaps of IM's & our home grown Aussie IM's came out equal or better than the best flowing units tested

Small update.

Hopefully will start stripping the car this weekend.

But I spoke to my diff & box guy today. He said the std diff should be good for about 500 - 600 h/p, aslong as i'm using x-ply slicks and not using the transbrake.

[thrash]

you gonna weld it? or is it an lsd?

[1320ft]

It's allready an lsd. A mate of mine has some spare centre's etc at his house that I am taking off his hands. (He used to have a starion diff in his 3700lb 10sec rotary corona)

I'm going to pull it out, give it to glen (diff trans) to go over and do to it, what ever he see's fit.

the only problem you will have is twisting the splined end off the axles where they go into the side gears, this almost always comes about after axle tramp, so make sure u run some REAL good quality rear shocks.

running the 6 bolt late widey diff eliminates the small axles..

I'd put money on your mate having Scorpion diff centres :D Can't see why someone would graft an obscure IRS diff into a Corona, while a Scorpion live on the other hand....

off topic but some eighties corona coupe's in particular did have irs rear diff/suspension, most of these came with the 3tgte turbo motor.

[1320ft]

Well, 90% ready for the dry ice next weekend.

Found a bit of cancer in the passenger side firewall though, but its a race car, so i'll just bodge it up.

Small update.

Tape Measure came out the other day. The decision has been made to toss the IRS setup in the bin and a 4-Link welded in place.

Diff will be the bluebird diff that did multiple 8.xx passes in Rocco's Rx-7, before going to the floater. Have ordered a set of spax double adjustable coil overs for the rear.

Front end will be going to a custom 5 stud setup, because I have ordered some of these:

modded XB falcon hubs for the front ;)

[1320ft]

Yeah, the Ford offset is more common.

Plus the rotors I think I will need will fit over the hub, but DBA keep them in a blank hat, so I can get them drilled easily.
