Ok can anyone complete the below please ?

Injectors sizes

Evo1-3 = 510
Evo 4 = ?
Evo 5 = 550 ?
Evo 6 = 550
Evo 7 = ?
Evo 8 = ?

I need some bigger injectors to give more fuel to suit new 20g turbo, was going with 550's, but think im gona need 600/660 to get good boost.fuel etc, ive heard evo8 has 600's can anyone confirm ?

Cheers
Ian

According to the buyers guide, it's 560 from the V onwards.

Ian

Ok thanks guys so it looks like the E8 ones wont be a cheap option then , will have a look for some 660/700's see whats about. Dont want to go bigger than i need as i believe it can cause delay problems if they are 2 big ?

Ive been tuning with the stock 510's and to get knock down i have had tweak the safc up quite a bit, now injectors are upto 90% duty at stock boost (0.7-0.8bar) with the 20g on...certainly flowing some air! ....will tweak fuel pressure up a little to give me a little more saftey margin, and see if we can get a little more boost out of stock injectors

Thanks Chris, unfortunatley they have a fairly bad rep in the US for bad dead time unless running high fuel pressure! ...shame as they are a good price, but as ever i suppose you get what you pay for ... think Sard or Denso are the way to go

evo 4 = 510cc
evo 5- = 560cc

early evo models were less than 510cc

From what I remember mate you run the risk of losing fuel pressure if the injectors are too big? You just need big enough injectors to keep the duty cycle between 60-80% I would have thought.

Yer ive looked at the slowboy ones Carl as ive dealt with them a lot, the PTE ones have a bad rep in the US DSM community for low flow rates and quality , the Densos are well recommended though, but i think ive got some pretty cheap 2nd hand ( 500 mile ) Sard 700's coming soon

Yer ive read that as well GlobalGB, and from what ive worked out 700's are the max i should go for, with maybe 660's being best to tune....will try the 700's and see how we go.

that's why I suggested the sard 700's
