GReddy Turbo Kit

meanmx · Postby **meanmx** » Fri Jul 27, 2007 1:00 am

Alright guys, I know this topic has been done to death but looking through the old posts I couldn't get exact answers to my questions.

I am looking at the greddy turbo kit from perfectrun. Has anybody dealt with this company and can I get it cheaper elsewhere?

Is this truely bolt on? As in can a couple of guys with a reasonable amount of mechanical knowledge but not having done this before do it in less than a day. Are there any bits missing from the kit that I would need to arrange before hand? Can the key simply be turned afterwards without any dyno tuning at all?

I understand that I can get a do it yourself kit but I am not after something with any fabrication involved and for minium dollars. The plan is to get it all up and running without having any time off the road as it is a daily driver and then installing an ebay FMIC in the nearish future. Then when things financially start to settle down I will look at aftermarket management, injectors and all the rest. The main thing at the moment is to get forced induction without down time. I am hoping for 95-105 rwkw afterwards, would this be reasonable? Anyway thanks for any help guys.

i don't have any answers for you as i have no experience with the kit, but just putting my hand up to offer assistance with the install if you need it. as long as i'm free that weekend.
as far as \"not needing a dyno tune\" i dunno, you would at least need some way of checking your fuel mixtures i think. but i think jake has a meter doesn't he ? you could ask him for a hand ?

you aiming for 95 - 105 rwkw AFTER doing the intercooler upgrade ? i can't see that being a problem. i got 98 rwkw on 7psi with my first, very conservative , rish as anything, saftey tune. my setup would be not too dissimilar to what you are looking at, i guess.

Do you have the specs of the kit?
How is the fuel being managed?

Maybe a link to the website.

95Kw is achievable without the intercooler, but it all depends on your state of tune (ie: you would struggle to safely get that just with a fuel presurre riser thingo)...

The intercooler keeps things relatively safe for the 95Kw...

I thought the Greddy downpipe became a bottleneck after 6psi?

You should be able to get it done in a day (safely 2) but i would like to know more about the kit, as i think the greddy turbos are only oil cooled?

I am running the greddy kit, although there is not really a lot left besides the turbo, dump pipe and exhaust manifold now.

I have purchased from perfect run ( a emanage not the turbo kit) and they were really good to deal with.

The kit can easily be installed in a day, and is definitely driveable with out a dyno tune. The only difficult part I found was installing the oil line.

You need to check if it is the american or jap kit, the american has a rising rate fuel reg and the jap kit a small electronic interceptor thing. I had the jap kit and it works well but i also added a rising rate fuel pressure regulator.

I would recommend looking at getting a emanage blue to control timing as you will find it very sluggish off boost with the timing knocked back (which you have to do with the basic kit.

If you want to know anything more let me know.

yeah i was wondering about the oil line... brad does it tap off the oil sender on on the other side of the engine or does it come from the back of the block on the hotside ?

if it is from the oil sender, it might be worth a trip to pirtek or enzed to get it modified to fit the other oil feed spot BEFORE you start the install, that would make things much easier.

and yeah my timing is retarded and it is sluggish off boost ,some kind of timing control would be a great idea. i'll be using megasquirt for that.

Yeah, I got a wideband

Happy to help out with some tuning assistance.
Can probably help out with fitting too depending on when it is. It can't be too hard to fit up.

Thanks for the info so far guys. Keep it coming. The more I know before hand the better. Couple more questions. Will the downpipe bolt straight up to the stock cat (this will be a temporary measure!)? And will it interfere with my aircon? Again thanks all for the info.

my dumpipe didn't bolt up, (the avo one) . a quick drive to mr muffler tho and it was sorted out (sounded like a v8 supercar but it was only a short drive :mrgreen:

)

you should be able to retain your aircon, so long as the pipes don't get in the way. when you fit yr intercooler you can fab the pipes up to get around it all. all my aircon stuf is still there, except for the belt. one of my pipes gets in the way of the belt but i will be fixing that eventualy be shortenning / moving the pipe. but yeah there are heaps of turboed '5s that still have the aircon working.

The oil line taps off the oil pressure sender, and is an absolute *&^%& to connect! So if you can get it modified i would recommend it.

The dump pipe will connect straight up to the standard exhaust/cat.

As for air con it is all okay, does not interfere at all. When i got the intercooler we also routed the pipes so i could keep the aircon.

There are 2 options on the exhaust side for the oil feed.
One is on the block. It is just a plug on the side. The other is a allen key grub screw on the head at the back (under the coils).
Both have plenty of pressure for the turbo.
My drain is on a tee off the bottom of the dipstick. Only issue so far was the dipstick kept popping up and hitting the bonnet. a quick coathanger clip fixed it.

Thanks for all the extra info guys. You are all confusing me a little now but esentially it looks like I have to get a new fitting on the oil feed line so it can fit the hot side of the engine and I have to do some cuts in the exhaust manifold. Will have to research it a bit further but it looks like this kit is the way to go for me and I will probably order it in the next couple of weeks. Anything else I should know write it down and thanks again guys.

i think the greddy manifolds sold these days have the relief cuts in them already, but i could be wrong.

the other things you'll need to sort out is to make sure you have all the tools, pipes etc. you'll need to tap a hole in your oil pan for the oil drin off the turbo, things like that.

oh and has anybody mentioned yet that you should have a look at miataturbo.net? they have a greddy section i think, as well as a d.i.y section that has a great f.a.q. sticky. check it out.

you don't need to tap the oil pan for the return line. the greddy kit uses an outlet next to the oil filter for the oil return, this makes it a much easier job.
