Hey lads I’m planning on building my first Barra in the near future and wanted to get a rough idea what work has to be done to the motor. I know I need to change all my rods, pistons, bearings, block and head machined ect... 1. I have read that people are running 1200+hp on a fg turbo crank that's been heat-treat and got me thinking if a fg crank would go straight into a ba-bf? Probably a stupid question but I have read there’s a couple differences between the ba-bf and fg. Only reason I ask is cause I can get a hold of a good fg F6 crank and I’m just planning on buying a cheap n/a ba-bf motor to build. 2. I’m looking to get around 7-800 on 98 for the street and around the 1000-1200hp on E85 so would I have to get the head ported and if so would it be cheaper and better to just exchange the head for a ported one? 3. I have been looking at the spool rebuild kit with custom CP forged pistons and spool drag pro I beam rods and going to run 14mm head studs. I’m a bit confused with all the different options like the all the oversized bearings. is it better to have all the bigger bearings? cause I’ve never built a high hp engine like this, I’ve only ever rebuilt diesels (trucks) and a couple old v8s with my old man when I was a kid. And with all the piston options I got taught by my old man the higher comp ratio in a N/A the more power and lower comp in boosted applications the more power but with technology nowadays it’s completely different from what I got taught. I know all these questions I’ve asked are simple and stupid questions but as I said I’ve never rebuilt a motor to give it more power. If yous could help me out with this stuff it would be great, I know I’m more than capable on putting it back together and for it to run like brand new, it’s just all this other sh*t just got me a bit stumped 😂😂 cheers boys 👍🏽

Hi all, I’m new to the forum and have started up my bf atomic built Barra in a Te cortina. I have this on the dyno and I’m not real sure on ignition timing since my Backround mechanical knowledge is in the diesel field. Mods are listed below: Atomic built 698kw engine bosch 2200cc injectors twin Bosch 535 running E85 precision 76/75 PWR W2A cooler FG intake custom exhaust manifold turbosmart 60mm waste gate turbosmart bov 2 speed glide 4500 stall 3:5 9inch any help would be appreciated. Any tuning tips especially with timing. Thanks in advance.

ive been running my car on a half E85/ 98ron sometimes. have an xcal 3 with a tune for just 98 too. after 5 years of sitting in the garage a semi-well know tuner on here is strongly advising me to dyno it again to check everything is still as it should be. with the reputation he has, and after knowing him for a long time I want to have him tune it.* he cant tune with sct gear though so can only install one tune. I def wanna run ethanol at least sometimes, so dont want just a 98 tune. plus I pick up 20rwkw by switching to e85 tune. he suggests making it a dedicated E85 car- but with a 40 min drive to the closest servo that stocks it I would want to fill some jerrys with it each trip. having said that im only gonna drive the thing once a week prol (if that). plus to go full E85 id need to up the injectors from 60LB Dekkas to ID1000's- which means more power..... never a bad thing. --------- I was always led to believe that ethanol separates molecularly if left in storage, but am now hearing mixed thoughts. any one had experience with storing it for a period of time? suggestions? cheers *having said that the original tuner did an ace job of the tunes he did all them years ago. still runs perfect imo.

I have a 04 xr6t auto it has the following mods: 60lb injectors, walbro 255, valve springs, monza cooler, knn filter, 3.5" dump, hi flow metal cat. Car made 292rwkw on 13 psi. My end goal is 300kw+ No more than 350 it's just a daily. Well my fuel pump is on the fritz and needs to be replaced thinking a walbro 460. good time to consider e85.. I love the benefits that e85 offers and it would surely push me past that 300 mark I've been aiming for many years. Filling up more often doesn't worry me I can get e85 5 mins from home. But what are the cons of e85? Short term & long term..

I have been reading some forums of people mixing u98 and e85. I have read the effects of 85 on fuel lines etc but only when running 100% e85. But I was looking at running maybe 70% u98 and 30% e85 or maybe even more 98 comapred to 85. My reasoning is that with the high prices of 98 mixing 85 would be a bit cheaper to run. I drive a 2003 BA XR6 with a redback cat-back exhaust. Open to all ideas

hey guys back for some more advice ive done gtx3582 tbre stage 1 cams built auto with stock converter plasmaman surge with twin pumps 044s all surporting mods so far ive only done the 98 tune with one pump but im looking into doing the e85 tune and ill be connecting up the other pump ive been told ill need a new fuel reg will need to do the fuel rail as well? im looking for 430 450kwish and into the 10s next meet next Q is about a converter what are people running (sorry about being in the fuel section) want It to stall to 3200-3500ish and not to hunt on its self thanks any advice would be great

looking to upgrade to e85 fuel in coming months just wondering if there's a fuel station in Townsville that has this fuel, if not how much is a barrel of Surcogen e85. if theres no pumps in town im still keen, wanna run my Datto (ca18) on it even if from the barrel

Hi guys, I keen to know what type of injectors people are using or prefer to use for daily e85 usage. Reason I ask is because I have been using the bosch ev14 2000cc injector an it seems to me from my experience with these injector they do not like e85, just from one day use of e85 my 2000cc injectors will shut close or stick, I have had 3 injector failures already and iv pretty much had it with them. Now I wonder if anyone has experienced the same issues iv had by using these type of injectors or any other types, by doing a bit of research it seems that there are lot of people that have had the same issue as me, it seems that issues arise because of a rubber seal inside the injector swelling by using e85 or fuels containing mtbe or are either oxygenated. Anyways from what I can see the problems are only arising from using the bosch 2000cc or any other type of ev14 2000cc injector, so my questions are can anyone recommened a injector of similar size cc, there are a few other names out there like denso, siemens, dietchworks, has anyone used these other types injector? And one more question can anyone clarify if pump e85 is oxygenated? thanks

Hi guys I thought id let use know after using e85 consistently for about 10thousand kays I developed a misfire after wot an a few lean outs at wot, anyways the problem to me seemed to be something to do with fuel presure. So I went on to do a bit of diagnosing, first thing I noticed was when the motor was cold it had a fuel leak right at the return line of the surge tank but when the car was warmed up the leak was not there anymore. I found it odd an strange but I came to conclusion that while the idle was up on cold start the fuel pressure would have been also which would have been why it was leaking. I decided to pull out the whole surge tank set up out and the fuel rail as well, the first thing I noticed was all the efi lines that were connected to the surge tank was all cracked, these were the only lines that was not e85 compatible. I knew that I should have changed while I did the other lines that were e85 compatible that goes from pump to rail. So I went on to check the fuel rail an I couldn't believe what I saw, I had a long strand of rubber hose jammed in my fuel rail, I couldn't believe what the e85 did to that hose lol just completely ate it away, anyways cleaned it all out an an went on to check my injectors out to see if they were all right. I started pulling all the baskets out to see if they had caught any debris but it all seemed fine an I went on to change the baskets aswell. I now went on to give the injectors a clean an I noticed a massive amount of black goo stuck on the pintle part of the injector(the part were it sprays the fuel out) the goo was hard to get off but I managed to get it as clean as brand new I reckon that goo would have had an affect on spray pattern because some of it was stuck on it real hard, apparently that black goo on injectors seem to be common after doing a bit of research on the net. People seem to think that it may be the additives that they throw in the fuel. Well I've changed all my fuel lines now to a new version of Gates Barridgate Greenshield E100 compatible fuel line cleaned out injectors an rail an now my car is running perfect, hopefully fuel lines hold up if not then I'll be going straight for Teflon lines an Speed Flow fittings. Well I hope this may help anyone that seems to think that they may have a similar problem, but I urge for people that may still have some efi hose in the system while using e85 to check on them an replace them.
