Poony_Tunes

Hi podmak

As everyone on this thread has said these engines were designed to run on 100 octane but in Aus models were tuned down to 98 (not to good of a tune I'll add) but it's because of the time when these cars were built there engines had a higher compression ratio (9:0:1) compared to a wrx (8:5:1)even more than a Sti (8:0:1 from memory) they did this to help primary to come on earlier and a the change happen quicker when secondary came on, they can be retuned for 95 octane but there can be power loss in doing so

Btw e10 in a B4.......well I wouldn't even put that in my lawn mower it's a very dirty fuel

Have looked into from mount intercoolers before like the scarles kit, from what I have read of people installing them and yielding little gains in performance except a little less heatsoak but I'm keeping my mind open with it


Would love to do an e85 tune but that goodness does not reach us in far North Queensland

I agree it is an Aus spec car with the AIDS tune so the would be a lot of benefit.
My thoughts are coupling the tune with the water/meth for an increase in timing, boost and being able to lean on it a little and a cooler engine.

6 speed fits no problem with as mosti said, i know gen3 auto tailshaft fits

 

I am running mrt exhaust dumps no clearance issues, and theres a hanger for primary dump that fits but not the other will need bracket made up easy fix

 

as far as what else is needed, 6speed clutch/flywheel, master and slave cylinders, your 5speed speedo hookup and 6speed transmount can use your 5 speed cradle as well as GD shifter 

 

front drive shafts are the same as well as your 5speed starter works with 6speed, theres a slim plate under clutch assembly that is different to 6speed

 

 

 

 

I do have my old 5 speed sitting around if interested.

hmm not too sure about the whine it might be normal

 

They have a pretty good diameter size clutch so probably an execdy replacement and you can go for a heavy duty but it might not have as smooth of a pedal feel/have bit of shudder  and get the flywheel machined

 

As far as the leak the big one is rear main seal thats a given to change when the box is off it can leak given time

 

Also there is a small bearing in the flywheel that should be replaced at the same time
