head lifting because too much boost?

be a lazy prick like me and install ARP studs without pulling the head off! That 19 year old OEM headgasket loves it :)

^^ Dodgy carnt...lol

you're forgetting I'm asian after all lol..

didn't you go to the darkside? why you still here? don't forget your turbo roots lol

sprayed more things black lol....

I might delete the charcoal canister and move the catch can there.. too much shit going across the engine bay at the moment :(

Yeah that's not a bad idea, but removing the charcoal cannister and placing it there looks more tidy as well as defective lol.

On a side note, my dodgy install new studs and torque down the head band-aid solution worked.

Was at Wakefield all day today pumping 1.5 bar through the motor and no signs of pressure building up in the cooling system.. yay for 19 year old head gasket and motor haha

lol with a fuel pressure gauge and external gate on show you're fooling no-one about it being 'stock, officer' :P

good result on the no-head-off head stud job then, might have to look at that further myself.

Hey guys, I'm still tossing up between turbos for my build.

To be honest I just want the most responsive and snappy 300rwkw on E85 for the street.

I found a build thread where someone had made some very nice results on the highflow 21U turbo used on a R34.

There are a few options for me but I'm unsure.

SS1PU (I had one of these in my R33 for a few years and loved it, Stao has altered the build of these over the years and they seem to have gotten even better)

R34 Highflow (currently have the turbo so it would be cheap and easy to sort, but I'm unsure if it's going to be nice and responsive)

R33 Highflow (more responsive than the R34 highflow and I'm not sure where this sits between a SS1PU and the SS2 in terms of response and feel for street)

SS2 (stao said this is strong and powerful delivery)

I've looked at a fair few dyno sheets but still can't wrap my head around it all, can anyone lend some input

The SS2 should easily get 300 on e85, like very easily. I'm running 260kW on 18psi very safe tune. It has a bit of lag, but not much, full boost is about 3500 and it just picks up crazy ! I've heard the SS1 is a more responsive version, but makes less power. 300 would be pushing it with the stock turbos, but that's just my opinion.

Pretty much everything I listed there will net 300rwkw on E85, but which is going to be the most snappy and responsive.

Stao mentioned that the R33 turbo on a R34 would want to ping.

not on E85, I've found it just loses power rather than knock like 98RON, it might knock but not audible like 98RON (from my self tuning experience)

Interested to hear the answers to this.

Stay told me the same thing but I'm keen for ultimate response on the r34.

Someone on here got close to 300rwkw on an r34 with the 21u highflow, e85 and blitz return flow.

I'm wondering whether the e85 combats the pinging stao mentioned.

I don't want Lag so very keen to try and make the 21u work on the r34.

About to get some ID1000 to allow running of e85

I knew someone who made 310kw on 19-20 psi on e85 with the u21 highflow.. tbh it didn't feel very quick but the dyno sheet it had a very v8 looking power curve made full boost at like 3700 or something.. blitz front mount, xspurt 1000cc, pfc and hks exshaust

I guess it's a toss up between the SS1PU and the 21U then because the 21U has performed 300rwkw on E85 on fair few setups now. The SS1PU was a beast on my r33 and should easily make 300rwkw.

Stao, you're the man with the kowlwdge. Chuck us all some ideas :)

engineering a new ss2 at moment. should easily take over 300rwkws on pump. will up result shortly. ss1pu makes similar power then 21u but makes alot more torque. there is also a new turbine wheel on thd ss1pu this year, should up hp by 15kws with no lose in response.

    • GCG is a good company, they're a major distributor for Garrett in Japan as well.
    • Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣
    • I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).
    • Ok thanks 🙂 I will higly consider this. Any "known" company for a good reviews and experience to send that off? Is that CJ-motor good one? Or go straight to GCG site? I need to use VPN to even find some of those "shops" let alone access them 🙂 
    • You can literally put in as much WMI as it takes to quench the combustion totally (and then back it off a little, obviously), and it will keep making more and more power. The power comes from the cooling effect of the water (and the meth) and the extra fuel (the meth, which also has massive octane). It is effectively exactly like running E85. One might be slightly better than the other, but they are damn close. But with either you can lean on the boost or the timing (or both) waaaay more than with just petrol and the results are similar. Here's the first thing I googled for an anecdotal bit of evidence. Can't access the attachment without being a gold member, but it is there for the getting if able to, or searched up elsewise perhaps. https://www.hpacademy.com/forum/general-tuning-discussion/show/wmi-vs-e85/
