Injectors and fuel pump.

Postby escoriasza » Wed Aug 19, 2015 3:33 pm

8m looking to turbo my 3sge most likely with the greddy bolt on kit and was wondering which 1000cc injector dynamics do I use? They have 2 different kinds. Also which fuel pump would be the most effective. And I've also head of people putting on a thicker head gasket to reduce compression to make the turboed engine a little more reliable. How true is this?

1000cc is well overkill for the GReddy turbo kit, sard high impedance 540cc will be more than enough (or Toyota Caldina gtt injectors are 540cc)

Double stacked factory head gaskets are common.

A walbro 250 lph in tank or similar (deuschwerks etc) would be fine, a Toyota Supra Rz fuel pump is also another option.

Thank you for the answers. Are there any real benefits to double staking the gaskets? Will my power go down in exchange for making it more "reliable"?

Your power will depend on the tuner, going down in compression means you can run more timing and more boost meaning it is possible to get more power.

It is not a necessity though, so is totally up to you. (it makes negligible difference in all reality, but is a good excuse to look at the condition of your engine before you turbo it)

Factory compression is 11.5:1 and I think double stacking factory head gaskets brings it down to 11.1:1 or 11.2:1, so still high!

Edit: According to this http://z4.invisionfree.com/lexusaltezza ... topic=7121 it lowers to 10.5:1 so it is a decent drop.

Hey soiled, woul you happen to have a part number for the id 1000 injectors? Also would the 1000s be good enough for running e-85 or wpuld we need bigger for say a 450hp turbo engine? Im also looking at the greddy turbo kit for stuffing a beams in a 1986 celica but also running e-85.

I have ID1000's running 470hp atw with 98ron and they're only running at ~70% duty cycle so should be fine (Not sure on how much more % over normal petrol you go with E85 but looks like decent headroom, if in doubt ID1300 are an option now I believe??) , don't know part numbers as I put them in about 5 years ago.

You really know your stuff soil. I really appreciate your help. Would you happen to know if the 540s would need some type of collars (part #63534). I keep reading different things on these.

The 540cc Caldina ones should be a straight swap, email the site trader Nick on Nick@nst.co.nz and he'll be able to sort you out with good prices and get you the right parts.
