You are correct - differential expansion (same rate, just different amounts of material) mean that the piston skirt is not circular when cold.

I run Omega pistons and their rings in two of my other cars - both NA though. Excellent pistons, highly recommended. Do they do a 2JZ piston?

Any luck yet Steve? Will you be able to do it with your weight in the car so we can get a picture how she sits "ready to roll"?

You could go shimless with the 3SGTE buckets.....not sure how much they cost though or how high you are planning to rev this thing.....just thought I'd mention it.

Is your existing turbo "alright"? I remember an odd post or two where you mentioned it had a very high boost threshold and the car seemed very laggy compared to TTC. Have you been out for a ride with anyone else with the same turbo? What about just a decrease in A/R on the hot side, what do you have right now?

Smaller more responsive turbo, perhaps DBB as well?

I got a little bored of mine and returned the interior to bone stock - no gauges, displays, beeps, buzzes etc...nothing. The fuelling was all well setup and perfect and I was only running 1.1bar so well safe on everything so no real need for the gauges. I added a TRD steering wheel, swapped my Tein top mounts for stock ones and recirculated my BOV, put the stock airbox back in and it was like driving a new car. :D

What's the setup under the bonnet...I did look in your garage but couldn't see anything about the engine

I am curious what the finish is like inside the elbow and whether the elbow thickness makes for a smooth transition inside where it's welded to the housing.... nothing sinister!

How was the 3040 on the Soarer....and was that with a 2.5l motor? Did you ever have it on a rolling road? I'm wondering what it'd be like on a 2JZ...

Did you ever fit this kit Gamer?

I'm interested but depends on the date. I would only really want to do a power run though....I think. We need someone who's been on the SRR to come along as well for a comparison.

How about all of the inner part including the inner rim where the bolts are finished in black but have the bolts and the outer rim in real shiney silver/polished finish?

Jamie - is there any chance of posting a photo inside the 90 degree elbow on the compressor outlet?

Glad things seem to be moving forward, what a pain in the ass! Was the wrong turbo shipped or was it the right one but with some sort of problem?

Any progress on this Vaughany?

bolarbag - your post just pissed me off due to pure bad timing and the fact that it just states the obvious. I was trying to make a sarcastic post by pointing out why you jumped on a 67DBB in particular being "pointless"....I was interested to know what made it "pointless" vs. any other turbo especially anything bigger or older or laggier. I think you missed the sarcastic bit in view of the fact that you jumped on my 4088 comment......yeah, that is my favourite turbo, best by far for longevity and reliability, that is why it is so expensive, so hard to come by on places like Ebay, and why it is clearly the turbo of choice for all the "Supra tuners" turbo kits I think you would be wrong to steer any potential buyers away from a 67mm turbo (in particular) on the basis of reliability or cam choice......especially on a road car running pump fuel. In my opinion a 67mm would be as large as I would put on any road going car irrespective of cam choice and after driving a few I would probably go a tad smaller. I certainly would not go replacing valve stem seals just for the sake of it unless they seemed to be leaking. I am not going to get into some lame ass keyboard argument crap - I never have on here as it always seems to pan out to be a total waste of time. I certainly will not reply to your dig about turbo knowledge or whatever it was...suffice to say you stick with what you know and have done and I am sure you will do fine. I will do the same. This thread started out about a potential group buy for turbo kits not a general discussion on engine maintainence. Your stating the obvious just wound me up but then I guess any new guys could benefit from a bit of that so...carry on, I guess if it saves someone some hassle and money then that is good. 1000 apologies for upsetting you, I will breeze by any future obvious comments of yours as you rightly suggest.

Is that aimed at someone in particular or are you randomly jibbering on in someone else's thread? Please quantify your idea of a "full overhaul" and "pointless" and perhaps seen as you like pointing out obvious crap you might want to say something about clutches, fuel pumps, injectors, sparkplugs, cooling, compression test, leakdown test and TC's as well. Would a 74mm turbo be any more pointless or a PHRS3 or how about a 4088 or even a 4088R. Do you believe for some reason that a 67mm turbo is more "pointless" than other turbos...ffs. Potential for what? I'd like to see you argue the toss on that one with Ian C. .....Ian you are clearly insane and ill informed (by someone!!) Why are you posting all this in this thread anyway. There are countless threads on the forum about single turbo upgrades - this needn't be a copy and paste of everything from those threads. This guy posted up about single kits - not cams, not ecu's, not reliability....it was an enquiry related to a potential group buy....not a "Please tell me what I need to do to have a decent single equipped car".

I'm interested if it's a 67DBB kit, especially if someone sorts it around a cast manifold.

Or into the exhaust via a check valve and slash cut.....nice! Lots of vacuum!

I have some hot side piping I could sell to someone to go with this...

I use a MKIII engine oil cooler for my power steering fluid, mounted in the nearside duct below the headlight.
