power up mods for the 20V

[dtour]

lol enough of the comparisons... i need some info on the 20v silvertop injectors..

just so you know i am planning on converting mine to run on E85 with plans to turbo it later.

i need to know what injectors fit into the 20v fuel rail? i have heard that 1J injectors may fit?

[Sam-Q]

1J and 2J, by memory the 1J are 440cc and I have some for sale if your interested

You have a PM good sir

planning to increase compression?? all the research i did regarding E85 on a 4age came up with very little reason to actually do it...unless u were running 12.5:1-13.0:1 compression very little power to be gained...

also make sure u run suitable fuel lines and clean the tank quite well prior to changing over...

as said, looked into this quite in depth...but decided against it...

1J are 380cc
2J are 440cc
USDM 2J are 550cc (low impedence)

this was talked about on another forum recently but for different reasons, i will look into E85 in the future (as you well know del ive got the compression) but for possibly an entirely different reason, that is to pass emissions. should i be EPA'd i will look long and hard at upgrading to E85 for the power and environmental gains.
but i do agree it would be a handful of horsepower gain, but its just where the gain would be that also interest me...

the only stuff worth running

to be honest, the reason i am going to convert it now, is in preparation for the turbo conversion. any power gains are a bonus.
all my fuel lines have been replace with speedflow lines and fittings, so i think i should be good there.

So what was it that put you off E85 totally?


Can i get a link to that forum/ thread?
is there really very little gain to be had from e85?




Cheers, so it looks like i will need 2j ones then.

if you going turbo then yeah there is a heap of gains to be made as you can run more boost, also a cooler intake charge as the alcohol content burns at a cooler rate that petrol, can run way more advanced igniton... so 25+rwkw gains will be had.
del and i were more refering to in a N/A application, where you really need massive compression (minimum 12.5:1) to make the best of it and you migh get 10-15rwkw out of it.

with your injector sizing you might need to get a bit bigger, as a general rule of thumb E85 uses 35% more fuel than petrol, but it also has a much higher "octane" rating then petrol.

the thread i mentioned:

Actually have 1st hand experience with a modification worthy of this thread, apart from the 3 pages of non-20v related material.

As per Frak's recommendation on many other forums (and the old forum), I purchased and installed the I-Mec trumpets inside the factory airbox (silvertop modified airbox) to a blacktop 20v.

The drivability is totally different after the installation, and feels like it has gained alot more torque right across the rev range, which confirms what Frak found on the street and dyno.
