Do the s2 V6 Fuel rails fit S1 engine.

[immortality]

Q. do the series 2 V6 alloy fuel rails fit on a s1 engine?

i have a suspect regulator and the alloy fuel rail looks easier to mod (drill&tap) to suit a aftermarket high flow regulator to suit upcoming mods that will require substancial increase in fuel flow

[88GreenVN]

I have 2 types. solid tube type and 1 with what looks like 2 plugs on the end

[immortality]

yeah, the s1 rails are black and have hex drive ends for the crossover pipe on the front. i want to use the alloy rails because i think i can tap em. the s1 pipes i definitly can't modify without a lot of hassle

[88GreenVN]

OK I have that type on each of the 88 and 89 VN's And have a solid pipe unit in the shed. I never fitted it - just used a few injectors from it.

you want the aftermarket reg after the stock reg in the hose really a lot of the aftermarket rising rate regs dont hold pressure well so normally run them after the stock one still get the same pressure control just the stock one holds the pressure better when stopped and during starting.i dont know if the manifold has suyitiable bolt holes to hold the injector rails down or not either

[immortality]

won't be using a rising rate reg. they are crap in my opinion and not needed if tuned properly with the correct injector sizing. i'll be using a adjustable reg so i can get more acurate pressure control.

the alloy fuel rails shouls also polish up real nice

[delcowizzid]

make sure its a bloody expensive one mate they are know to run at different pressures from day to day and heat effects them i know a lot of people have issues with them never keeping pressure correct even with the $200-$300 ones all show not much go stock works suprisingly well really

[greenfoam]

I'm kinda thinking the same, you wont be able to make enough boost to need really big injectors or more pressure, just super 6 injectors and stock regulator is the go

you still up man you never sleep LOL i didnt make it last night either might have a snooze later

Hey man this video explains my entire life and why I never sleep (until I pass out)

hahahaha funny as well i think this thread has been highjacked enough sorry immortality but the video was worth it LOL

on topic what brand of reg did you get

[immortality]

no reg yet, but i was planning on a magnafuel one

great vid. that does explain a lot for me.....

working on the fuel line fittings for the nitrous kit. was working on a permanent fiting for the fuel pressure gauge

[delcowizzid]

im with foam ide spend the money on better things LOL.the stock reg is good really and it will increase pressure with boost at a 1:1 ratio.could spend the coin on a wideband hehe just fired mine up now love it too.DIY JAW wideband from New Page 1 and VX commodore 0258007200 bosch wideband sensor

[immortality]

did you get it pre-assembled? looks ok. how does it go with the standard tune or are you using it as a standalone setup?

[delcowizzid]

nah got one from alan in kitset form for testing and reveiw of the product freebie.took about half an hour to put together.easy as .only got the sensor this morning so just bench testing it.ready for in car testing now.will probably just use it as a standalone unit and run the stock narrowband too.or pull the narrowband while tuning and plug the wideband in the hole and turn off closed loop and the O2 error codes.then reinstall the narrowband when finished tuning.it does have 2 outputs one for narrowband simulation and one that can be another narrowband sim or can goto a narrowband guage and display wideband fuel ratios but it has a nice digital display anyway.and logging software.has 3 inputs rpm and 2 X 5 volt inputs for map or egt probe etc.will hoipefully test it this week in car.
