ok time has come to start designing my engine for my projuect nect year
10k budget

engine ive got (dont have to use but) is an ea 4lt (yes 4lt is not orig)
the superchragers i was think of are using are off the 1ggze engine and are postive displacemnt twin screw.
the intake manifold i was going to use is a el one
exhaust manifold custom made for twin turbos
turbos dunno

any help would be appreciated

For $7.5 k you'll have 250 + rwkw with Gt3540 turbo, 36/ 42 Lb injectors, 8860 EMS i/c etc...Power when you want it without dragging them s/c around when you don't have to saving some economy..Imo...

why the hell do you want twin superchargers AND twin turbo's?

Exactly a fargen[sp] lot of hassle for very little gain if any...

If you put all of the effort time and money you would be putting into a twin s/c, tt motor, imagine wat you could do with just on turbo on the side

Youre 17, and you think that youre going to have a twin turbo twin SC setup? Dont let me doubt you or anything, but try for something a little easier and/or cheaper. At 17 everyone has dreams of these things, yet money doesnt come easily. I wish you luck, but there arent many out there that fulfill their dreams as a 17 year old

Yeah dont want to squash any aspirations but do some serious maths first dont go starting something your hardly going to finish. Remember no one ever makes money off these things so unless your planning on finishing it and driving it for your own enjoyment just give me the money and I'll give u a s**t heap of a car, cut out the middle man.

youd be better off choosing one or the other, it be a lot of bother trying to do both, and have you thought about insurance, if you said you had a twin superchaged and twin turbochaged engine, no insurance company will touch you, but this isnt helping you, try contacting these places, both are reputable and for 10k they should be able to help you come up with somthing good.

hope this helps some.

LOL, kids they make you laugh dont they. Fast and Furious movies have alot to answer for, every kid or bubble gum chewer as i call them are all experts on turbos and NOS, just ask them.

yes i know i will never make any money off it and im never goign to sell the car and i dont really car how much money it cost me and yes i know the worth of money and yes before you start jumping to conclustions i get it all from my parents no i dont yes they are pretty well off but i work and have worked for the last 4 years sumtimes working three jobs so now htat thats outa the way lets get back onto the engine


umm for year 12 next year in systems automotive you have to do a project and mine will be this engine......

not sure how far im going to go with it next year probley just up to the twin superchargersdepending if i buy my cbr.

my resoning behind the twin sc was that they are positive displacment so i would have sum boost off the mark and these superchargers and running 6-7psi on 2lt engines and so i thought on a 4lt use 2. there is a person who has put on a vl ex (rb30) and it gos faster then the turbo vls, but i just wanted it so i didnt really have any turbo lag

i was going to remove he aircon and put the two s/c's there on that side and just have the two pods behind the left headlight then the twinturbos on the other side (the exhaust side) and have them running into a intercooler at the front (one of those hybrid ones for 400 off ebay) then meeting up with the sc output wuth a y merge then continuing to a el intake i would move the batt to the boot.
i personlly really am just doing it for the looks and bragging rights off a twin sc twin turbo eb because im pretty sure it would be the only one in australia and the look of peoples faces when they see four pods in the engine bay two eitherside of the motor

im hoping for between 200-300rwkw and i just wont it to be nice and responsive

what i need help with i the cost of the ecu and stuff like that

what size injecters
what ecu
how to join the two forms of forced induction up
how to get it to idle not to bad just so it doesnt stall al the the time, i think i have to vent off all boost throm the sc's with a wastegate thats moded or sumthing

thanks for ur help guys

but if you think just turbo will be beter for street then im willing to listen

hey guys just updating u ppl bought a ef motor today (view post ef tickford motor in 6cyl forum)
and im only going to twin supercharge it now as i am buying a bmw 325i 1996 model, but ill still have my good old trusty eb

if you want use a super charge and a turbo , do it - but use 1 of each .
hook it up this way Pod - supercharger - intercooler - turbo then to the throttle body .
Hope that sets u up a bit dude ,
ECU u could use a motec system ( full install )

I can only suggest that those little superchargers are going to be a hindrance as opposed to an advantage. Think of the flow two turbos will be pumping - those little blowers will stop the air in its tracks!!!!

Keep it simple dude, go for a single turbo. Or if you feel the need, a vortech supercharger being fed by a single turbo.
