Supraclean's "Drift Sicle" Project

[Supraclean]

what's your verdict on those PBM coils?

Use a different compression gauge and see if the numbers read higher. Mine read 175-180 solid all across. Your number is still decent considering they are consistent throughout.

Thats a good idea, those are great compression numbers man. Wouldnt your cams lower your compression/ with your metal head gasket?

Maybe i have the wrong info/ impression tho. I just have the 256 poncams.

The Coils are holding strong, honestly I would say they are way better the some entry level coilovers I have had in the past.
With the SLL spring update/ mod they offer They are lighter and seem to perform better then prevous models.

I have never tried out high end DG5s, apexi, hks etc. What I will say is compared to my friends Hsd 12/10 spring combo the PBm 10/8 seem to rebound much better for my driving.

Bang for buck coilover is what I say.

you should do the PBM solid rear subframe risers. will raise 1 inch! which will always help your rear end geometry, get the axle more level and super easy instal. thats the route im going with. thought id share. i already got my bushing out, just slip new ones in with epoxy and ready to go.

Thanx Marc, yea I considered there subframe riser but to be honest I feel that I would be adjustable lower control arms to benifit from the altered geometry. My car is not low by any internet standards, just an inch or 2.
I mean id love to buy some driftworks front and rear LCAS but right now it is not in the buget.

I have bings solid bushings going in combined with my energy suspension kit. Just talking about it is geting me amped to drop that subframe.

Did I mention I picked up a 2way diff from the infamous Ian Fournier?

The metal headgasket increased compression (machined head + stock thickness hg = higher compression [a little])

Thanks for the feedback on the PBM, I love my HKS pro too much to let it go for now anyways.

Gotcha that makes sence. Either way Im going to need rings this winter/ before tune. I mean while im done there I could get carried away. I would like to see it run one more season.

Yea for sure man, im sure your hks will do you fine. Knowing your style in car parts mike id say some stage 3/ variant of Kw. They dont have anything listed for hcr32 but im sure it can be done

[M13]

nah, a friend confirmed with me that the ones I have right now are pretty much the top model I can get for GTS platform. The only thing I would replace these with would be Aragostas or Ohlin (gtr based)

Winter Update December 2012

Round out the season with a Car show that our Local car club attended, the HNSCC guys helped me clean her up and this is how she sat.





Good Friend of mine Mr Taylor, with his son Dom sure to be a Drifter when he grows up. Any guesses who hes named after:P


The Car has a lot planned for this winter and to be ready for 2013 Season Driftwest Series of Am drifting that happens out west here.

I have already started to break her done and work on the 3 major areas that are been focused on:

- Weight Reduction, Gutting and Cage



As you can see that's just the start as I still have to clean it up and remove all the wiring I don't need. Most likely the speakers will go I do love the JLs but that can go into my next car. Do I dare say R34 or S15.

- Front Sound deadening will stay just for heat treatment as I don't want to burn my feet. No like the weight savings, money will be worth it atm for Dei heat tape or anything like that.
- Full Dspec Cage will hopefully be going to be Done by Mr Rob parsons out of Lethbridge will include the full jungle gym with a couple addition's like seat mounting. Maybe some bash bars.
- Fia Gear is coming along with Seats been Sparco US EVO, Firesuit, undecided on harness yet


Engine teardown, and rebuild:

Head is off and block is disassembled, I wanted to prove to myself that I could rebuild and engine and really get to know the rb20.





Surprisingly after 20 years and the 3 years of Drift abuse she was still holding together pretty decent:


Bearings had normal wear, #2 was the only one that I found that had a noticeable small groove in it so other then that im happy with how she looked.

Parts that I have going into here are:
- Rb20 ACL Main Race Bearings
-Rb20 ACL Rod Racing Bearings
- New Oem Gaskets
- Cometic 80mm metal Headgasket
-Oem oil pump
- New crank sprocket
- New Hastings rb20 piston rings

(all timing components and water pump are have less then 500kms)

Hopefully she goes together smooth and brand new compression before tune.

I wanted to share my timing sprocket pull:


I don't have the time for messing around with the sprocket, Im getting a new one anyways. I have pulled 3 now and some slip right off, this one felted welded on:P

Drilled tap and died and pulled her out with a harmonic balancer, boom done.

Last but not Least stage 3, Suspension and Diff

I have wanted to drop the subframe to replace the warn out oem bushings.

Plan of attack includes:
- remove subframe to clean paint
- install Bings solid subframe bushings
- New Energy urethane arms bushings that don't get replaced already
- Install 2way Diff (not sure on brand) Tomei or OS giken im told
- Driftworks Front a rear Lower control arms

The Diff will change the care grip and lock capacities a lot compared to my old VLSD, honestly I should have bought one along time ago, Mr Ian Fournier hooked me up with a spare out of his legendary V8 supercharged R32 driftsafari beast. Thankyou again good sir.

WHERE'S LETTY DOM? WHERE'S LETTY?

That kid is awesome and great car man. Merry Christmas!

[amnash]

wow wish I thought of that when removing my crank sprocket

[Supraclean]

wow wish I thought of that when removing my crank sprocket

Yea worked out well seens how I wanted to get a new one anyways.

Mid Winter Update


I wanted to share with everyone not just the good times but the good,bad and the ugly. Now take this for what you will this is only my opinion on two of the part selections I HIGHLY REGRET in my rb20 build to this date.

#1

GODSPEED Rb20 Topmount Turbo manifold

Original Design


Modified Design:


Work Done to manifold:
- external wastegate flange chopped and welded for 44mm tial flange
- manifold flange machined....as it was not flat
- turbo stud holes retaped as thread where complete crap

At the time (3 years ago) there were not a lot of info in topmount turbo rb20s. M13 on here was about the only one with good documentation and was very helpful. Even im sure its been done for years even on other threads/forums your very limited on manifold secections.

I always thought that because at the time the $$400 Godspeed manifold was a bit more expensive It was not going to be a bottom of the barrel compared to say the $200 you find on ebay. I even bought the setup with a wastegate from a member selling them as a Vendor on Gtrc, which further lead me to believe that this was a better choice and a CHEAPER alternative to the Fullrace manifold.

Like I said I hadn't even heard of 6boost nor even seen an rb20 manifold in threads for them, Now I know and look at even choices today. Theres Doc,Lovefab,peak tons of manifolds to choice from. The point that I am getting at is with everypart you choice for your car don't base what a vendor is selling of what "has work for a select few".

The manifold over its about 3 months of use in 2 years had cracked around the original welds:




Id like to add I could have braced the manifold at extra charge/ if you can weld yourself. Hell you can even get it ceramic coated to help combat the heat treatment.

I even have FLex bellows to deal with any if at all exhaust movements or stress on my downpipe/screamer pipe. Upgraded exhaust hangers is also another addition that I recommend that was passed on me via M13/Skym

In the End buy a quality manifold/ buy the tools and sitdown and build yourself your own. I am sharing this not spike up conversation on what should, could or would have happened or extra causes. I am just sharing so that when you are building your 20,25,26,30 If it isn't common knowledge about THIS manifold or similar ones, you now know.

#2 On the Part Purchase Regret list


Ebay Special Rb adjustable cam gears

- I figured how can you really mess up a cam gear right? Ill even double check the blots and make sure they are secure when I assemble the engine. Done and Done.

On dyno day she and the rest of the parts help up perfectly fine until a couple months after my tune was off, there just wasn't something right about my ignition timing and I had nowhere near the 341hp she was easily putting down at 13.5 psi.



In the Wise words of Robert Downey JR, "You never go full retard"

O Hello! whats that? The Bolts in this picture are More then hand tight, which you might think is the cause of this problem. Its not they are and were very much torqued down to proper spec.

So which leads me to think the clearances are out, Either way they are now on what I call the WALL OF FAIL. A reminder to myself for future builds and any of my friends with parts purchasing.

I wanted to end this section by saying I have Reworked the exhaust manifold and it has seen fresh Tig welds aswell has personal flange File ing.. I cant spell. With the addition of some DEI heat wrap to combat under hood temps aswell.


On too the New Year and new Beginnings:


Took the car for a little spin, aka have my friends push me on to the trailer, even just sitting in it on the floor all gutted/no front glass it brought a smile to my face.

Driftsicle Is off getting a full Formula D speced Roll cage/bash Bars as we speak. I shall update once I get her back with the goods I compiled of the winter.

[MidnightBlue]

love the build thread, so looking forward to seeing you tear her down to the frame

keep up the good work.

[Supraclean]

Thanx Midnight,

Yea at first I was kind of sad to tear out the interior as I love it so much. This is the path she is going tho, im still going to get insurance and drive her on the street once and a while.

Cant waiting to see what it weighs/ to feel how much more stiffer the chassis is with the Roll cage. Hopefully the bash bars save the shell aswell once I let it all hang out.

[nick-nismo]

Nice! I like where this build is going! What are you hoping for weight wise? Mine weighed in at 2930 in relatively stock form
I have that same manifold aswell, hopefully mine doesn't crack. I'm really regretting not putting flex sections in my downpipe or bracing the manifold

[Supraclean]

Thanx Nick,

Id like to see the Car at 2800 without me in it. I have deleted alot but still have a bunch of ideas things to delete. Idunno if ill go to a tube frame or not. Most likely not as the rulebook for most of the events ill be doing.

As for the manifold just keep and eye on it. If you notice its taking longer to spool up or you get an idle hunt thats where Id start looking. Also make sure to use OEM exhaust gaskets manifolds with SS tend not to seal very well from my experiance.

[M13]

looking good, getting motivations for my car.

stay tuned for my build (If I ever get to it lol)

good luck and best wishes.

[Supraclean]

Thanx Mike,

Indeed lets see what you have been up 2!
