From memory its 7cm...so you have around 1.7cm worth of porting to do. I will send you the gasket with it so you have a template to work with.

Cool, thanks 
still thinking about whether it's worth it though, it's a lot of porting to do.

Wont take long with a burr. Maybe 30min with a drill. Die grinder will do it in 10
Oh, that's a bummer I love keyboard gladiator fights LMAO
That 100 octane from united is a blend of 10% ethanol.

I wish I was that proficient with a die grinder, but I only have the not so bitey bits and to grab another bit costs $50 or so, add to that the time and well tbh, I end up at the "not worth it" place. I picked up the manifold from Jamo anyway, so a the very least I can grind the other out an have a spare. I almost have enough parts to build a second engine
I think I'll stick to 98 RON, I don't think we'll have E85 up here for a while which sucks nuts because I'm just about to get bigger injectors, but they won't be large enough for an E85 tune and I'm a bit dubious about getting ones that are monsters on a 98 tune. I read some articles on E85 an from a performance perspective it seems to make a bit of difference but like my wife said "just run it on avgas or put a bunch of octane booster in it", "ok hun, you can pay the fuel bill then" LOL Just a point of interest, how much cheaper is E85 than 98 in Australia?
hey jamo, are ya sure that the exh manifolds 70mm? just going off memory my evo exh. manifold outlet was about 55 (im guessin 53.3mm as the verniers say above) and the t/b was around 65mm
hey ben what size is ya t/b, gsr/rvr have around 52-53mm t/b as to the evo's 65mm t/b
and i think ya wont have to port ya exhaust manifold, but probly the intake mani to accomadate the bigger t/b,

E85 is much cheaper than 98. 98 Where I live is around $1.65, $1.70 at the moment and E85 I never buy but I know it's alot cheaper. The 98 is better on fuel economy though and much better for the motor for cleaning all the carbon deposits.

Ive just went out and measured it and its actually 64mm. So your guess was as wrong as mine !!

My TB is 53mm and the manifold is not much bigger and it came with 450cc injectors too, looks like all the bolt ons are all SSG stuff, such a bugger too as I have 2 of everything :fuuuuu:
All good, still want it to save me porting out the other one, spares are good

I read an article that said it is at least 30% less efficient than regular fuel so you have to put more in to compensate, I suppose that's why some peeps run 1200+cc injectors, it does have more octane than 98 though, but I'm with you, I'd prefer to run 98 over anything else

If you running 1200 injectors on 98 I thought you would need 2200 on e85. Thats alot more than 30% more fuel going in. I would budget it at nearly double the amount of fuel.
Its basically methanol without the birth defects and blindness.
But its another 25% more grunt

I'm a big e85 fan, but it does have it's negatives,
positives- has a higher knock resistance than 98 and in turn it means ya can run more boost which obviously means more power, its cheaper, an call me weird but it smells good too, lol,
on the down side there's no real standardization with it meaning from the pump it could be as low as 70% but ya can avoid it by buying drum e85, another bad thing, real bad thing is that it seems to be clogging inj. which obviously leans the engine out and BOOM! Unsure wether it's just pump e85 or drum also
easy choice for you fella's though! Just thought ya might like some info on it

Are you saying you sniff petrol BYBY5L? :lol: JK, I know exactly what you mean, I used to love the smell of the speedway bikes when my grandad used to take me. How often do injectors get blocked by e85? Thanks for the info too BTW
not sure how often, few theories out there are that its the oxygenator added reacting with inj o rings, or shorting the wet winding insulation and stuffing the mag field used to lift the ball/ plate either way its getting put down to the MTBE or the oxygenator used,
and yea the smell automatically makes me think "yea that must go pretty hard" think thats why i like it,
