Hi All

yes like many of us XR owners around Aus... The stage 1 tune has lost it's appeal & now bigger things are on the card.

Just want to confirm that've there's no reason I can't build a NA barra engine into a turbo? Would I be better off going for a BA/BF  or FG donk?   

The plan is spool rods/forged pistons, arp head studs & crow springs/retainers. Of course a standard reco of the head is also in the plan. Head gasket recommendations? My plan is to tune this to 450rwkw. Any other advise would b awesome

 

cheers

if sticking to the 450kw area

 

just buy a FG f6 short motor throw it in away you go. 

 

throw in head studs/ valve spring, all your bolt on ons and your good.

 

assuming a good tuner is used as well.

If I were to do it all again, I'd just do valve springs, oil pump gears, head studs, rods and freshen up the head. (assuming bottom end is mickey mouse)

Im having the same head funk atm with this,

You can 100% do a NA build, id go which ever motor has done the least km.

 

Ive been looking over Atomic 698 phase 2 kit 

Or Spool kit, or F6 short.

 

F6 short will get 95% of the way id like to one day go,

Atomic 698 is all the way and then some, the price difference is about 10k though :ermm:

Ad to that a full drive line transplant = FARK

build a high compression motor just for E85 hahahha but watch out you'll probably have mattyp come and actually recommend this.

 

Well you want the best bang per litre high comp boost on e85 is the way to go

All about that BSFC!

But in reality most aren't huge fans of efficiency like I am or have access to ethanol close by. The standard low comp pistons are incredibly versatile. Can even run 94e10 @365rwkw and done 12 flat on it with huge gearbox issues.

Fg f6 has a stronger short block than the xr6s, I believe it's bigger rods. Best to ask the guys who've pulled em apart 100 times

Who's your tuna?

Won't do a high- comp turbo to run on E85... Wud just consider tuning on E85 4 extra tuneable power ... I have the Herrod E85 compatible pump so it allows the option... My tuner 4 current tune is Tunehouse... But am considering spending a few weeks in Melbourne for a holiday & getting Nuzpro to fit the upgraded ZF box & tune ... They're proven & cheaper than tunehouse
