Want to reach 500whp(suggestions)
My Parts:
Stock 2.0 block with Kelford 272, ID1000 injectors, 255LPH pump, large intercooler/piping and 3" TBE/O2 etc..
The car is a street car, not for competition work - but 500 WHP on stock block is the target and the least lag, giving the most power possible in the 4000->7500 range.
So what are you suggesting is the best option - EF3/4 are both stock frame. I could get close with a bolt n TD06SL2R-20G for 1/2 the price
of an EF3/4 and get around 430WHP max - but thats what most people do..
The question is though is could an EF4 make 500WHP without meth with my mods, expecting intake temps/backpressure to be lower but is it really an option for a street car.
An EF3 would make it with meth, but thats another $1000 plus buying meth regularly but would probably be the nicest to drive, being more responsive.
Thoughts?

Hi Guys,
Why consider an EF4 over an EF3? An EF3 is rated to 550whp and would surely spool up faster (300-400 rpm slower than stock).
I'm ordering one for my JDM Evo 7 (same as an 8) stock block with Kelford 272, ID1000 injectors, 255LPH pump, large intercooler/piping and 3" TBE/O2 etc..
Expecting 450 WHP on pump at 28-29PSI and 500+ with Meth 32-24psi.
Seen any Dyno results for an EF4 ?

E85? **We WISH** in New Zealand. The best we have 98 Octane which NZ Speedtech advise is same as your 93 octane approx.
Thats why heat/detonation will likely be an issue and so Meth would be handy. I thought maybe 50/50 water meth as I know water injection along can drop exh temps by 300-400 degrees alone. Great for keeping stock pistons in shape.
One other thought - You can get a TD06SL2-25G with an 11.5cm housing for same price - approx $1000 nzd landed. I know its cheaper but hell, that sounds like a great deal. 850 CFM (560 BHP). from 4700 RPM it craps all over a 20G from dyno sheets I've looked at.

So a walbro 255 with 1000cc injectors would support an ef4? What about wastegates? Stock or atmospheric, I'm gonna pull the trigger on the ef4 and do it. I'll probably have to drive out to WA to get it tuned again but it sounds like the best choice!!
On pump gas, yes, my friend. The EF4 is pretty fun. It is an internal waste gate turbo. I have a proposition for you via PM.
It will support it the turbo but your not gonna make 500 hp on pump gas. With this turbo a single walbro will work ok but if your planning on running e85 then I would get that first. In my opinion on pump gas with a single walbro, 1000cc injectors will make you some ok power but if 500 is your goal then I would go larger injectors. The ef4 also comes with the 25psi wg so you should be all set.
I agree and if you run 91-octane with a single Walbro, you will be around the 410-425whp range safely. If he wants 500whp+, then 1450s and a double pumper is the only legitimate route.
With proper setup the walbro 400 will make about 650 whp. I was gonna go with one of those myself, but with building my motor soon I would run out of pump yet again so double pumper was the way to go for me. If e85 isn't available it will be more then enough to take on what you need.
OK, so your goal is to make 500whp on 91-octane, right? Well, that is going to be tough and I would say impossible with even the EF4 (which is larger than the FP Black). I could only squeeze a safe 405whp with the quality of 91-octane we have here in southern Arizona. With a better quality, 420-430whp would be the limit.
