What sort of injectors should I buy? 1991 rs legacy with td05

[slystiguy]

So as per the title I'm looking for a set of injectors...

There are so many options here I really don't know where to start

Firstly my engine

ej207 sti block

ej20k sti heads

intercooler+exhaust

currently stock grey injectors with split rails

td05 turbo on 13psi

So my estimation of max power is around the 220kw mark with the td05 maxing out around this point. Dunno what the block would be capable of.

Anyways what size minimum should I aim for? I was thinking 700cc would be smallest I'd go for but do I really even need to go that big?

The other options is converting to a top feed setup... What are the advantages of doing top feed over side feed?

I'm also open to suggestions on where to buy from.

DSRturbos can sell a 1000cc top feed set for $419 + rails setup costs which adds up to around 600-700 by the time you get fittings ect.

Alternately I see on ebay I can get a set starting around $350 for 550cc and add about $50 every 100cc

What is everyones thoughts?

Minimum size?

Top feed yes or no?

Where to get cheap large side feeds?

Here's a pic of my current bay setup for some attention hur hur hur (still a work in progress)

Get 800cc minimum. Then you can throw a man turbo on and retune later.

roger that.

cheapest side feeds I can find at 800cc are around $450 landed +gst +maybe tax

Worth going to top feed on early engine? might be just as affordable and easily up gradable in future too in comparison to side feeds

I got just on 200kw from standard ver3 yellows (440cc) and a td05 on about 19psi

You can get later model yellows decapped, I'm currently getting a set done and tuned for my car, they flow just on 800cc.

talk to tony at Dtech in tauranga, he's doing my injectors for me

Convert to top feed. Can always start with a set of sti pinks and then upgrade to id1000's later if going to a huge turbo. But they're going to better than most side feeds.

Ye id just go to top feeds personally. 1000cc dsr jobs and try find used conversion rails.

gotasuby does them

Wildturkey uses Silvia side feeds, go straight into the stock rail. Think they're 475cc or something, his BC5 pushed 226kw on a dyno with the same setup

Lol yellows are 440cc f all in it. If early v1/2 mani could use later side feeds 550cc or whatever they are the blue legy ones.
