supra2 Posted March 10, 2013 Report Share Posted March 10, 2013 Hi Seb, I found some old picks of my ra23 you asked for. Quote Link to comment Share on other sites More sharing options...
sebsta Posted March 10, 2013 Author Report Share Posted March 10, 2013 ok cool ours has a big booster off something like a hilux, and dad and i figured out what the funny divider thing does , it has a valve that runs through the both rear and front lines , when pressure is applied to the front it cuts pressure to the rear so when you jump on the brakes it only looks the front. and cuts the back. who is he talking to about pistons I'm hunting some dowm myself Quote Link to comment Share on other sites More sharing options...
sebsta Posted March 10, 2013 Author Report Share Posted March 10, 2013 Hi Seb, I found some old picks of my ra23 you asked for. hi craig that looks awesome as :) what engine was it running? Nice car ,do you run cams or amsag events. Shame about the off ,but it happens ha ha :oops: rob hi rob , we are running cams events as there is no amsag here in vic :( haha yeah oh well at least it is all straght and good now and we can laugh about it Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted March 10, 2013 Report Share Posted March 10, 2013 it has a valve that runs through the both rear and front lines , when pressure is applied to the front it cuts pressure to the rear so when you jump on the brakes it only looks the front. and cuts the back. yep, that is the brake proportionaing valve and it does exactly what you say.. which is why I want it all ripped out and an adjustable one put by the handbrake. We are lucky that the rear slaves we picked make the rears lock up with the pressure that valve lets through. Steve is chatting to Nick Arias, but I don't know him or where he is from.

Love the RA23 Seb! I'm interested to know what you did to the dash to fill in the cracks? Look way better! :) I understeered off and bent the same side in my first rally ever so yeah, shit happens but there's so much more fun to be had! :) In regards to the pistons; Nick Arias the 3rd is basically the bloke in charge at Atomic Speedware (their website is currently offline) in America that makes Arias pistons. You can't buy off the shelf pistons anymore for the 18R-G, so no matter where you go they are a custom job. I enquired to JP Engineering in Adelaide who make custom cast pistons but you're looking at nearly a thousand dollars and they didn't seem that keen to do it. Most of the 18R-G guys seem happy with the forged arias pistons. They offer whatever bore and comp ratio for the same price as far as I can tell. I'm currently waiting to hear back from Nick but this is our current conversation. Hi Stephen- Thank you for your inquiry. I can supply a custom forged piston kit (pistons, pins, rings & locks) for your 18R-G. Your price is $652.00 for the complete kit. Process time is 4 weeks, plus one week for coatings if desired. Custom piston options: Tool steel pins (over 20# boost): Add $60.80 TOTAL SEAL gapless top ring set: Add $118 Coating, ceramic crown: Add $112 Coating, Moly skirt: Add $112 Shipping USPS Express insured will be $94.00. I can also supply a PAUTER connecting rod set for $820.

supra2 Posted March 11, 2013 Report Share Posted March 11, 2013 Did you know that CAMS now allow you to use a 1st gen 3SGE with carbs as a replacement for the 18rg and still score points in the state prc championship. We ran and devloped a 18rg for almost 5 years when I started rallying. But it always seemed to be lacking something for a 2lt twin cam. These engines have a great cyl head but the long stroke lets it down. The high comp pistons we had were almost a V shape wedge crown which upset combustion and flow. This was over 10 years ago now so the shape may have changed. Just a thought as you may spend a lot of money, and like me, and be dissapointed with the results. Like Neil Bates, I reckon a 3sge would give you more value for your money. Quote Link to comment Share on other sites More sharing options...
TOMMYS Ke 11 Posted March 11, 2013 Report Share Posted March 11, 2013 Hi there Seb if you wave a look on Thomas thread TOMMYS ke11 page 9 you can have a look at what our ra23 looked like both before and after! let pics tell the story (shit happens).

airocobra Posted March 11, 2013 Report Share Posted March 11, 2013 Agree 100% with Supra 2 . I ran a 18RG in a RA23 ( GROUP A RALLY CAR ) the more money we spent the less drivable the car became . Eventually we blew the engine and with a limited budget just put a stock balance 18RG in and bugger me if we where not quicker. Gen 1 3SGE is the way to go and you know where youcan get one built.

altezzaclub Posted March 11, 2013 Report Share Posted March 11, 2013 Don't encourage him, he'll be trying to steal the motor out of my Altezza! As far as I know the 18RG is 88.5bore X 80mm stroke, so its more than square. I think its the 2valve design that limits it more than the stroke, but the main thing is have it hauling hard from low revs so it gets you out of the shit drifting in a corner rather than pulling 8300rpm down a straight. Have you got any photos of the pistons Craig, it sounds like another reason to stick to 11:1 rather than 11.5:1. Did you do any work on the crankshaft apart from balancing it? If we're going to seriously build a rally motor I'd like it lightened and knife-edged. What flywheel did you use? ..and did you ever use larger inlet valves??

supra2 Posted March 11, 2013 Report Share Posted March 11, 2013 Yes your right about the stroke, I was thinking about the stroke on the 22re we built. I don't have any photos of the pistons but I remember them looking like someone had stuck an iceburg on a flat top. I remember we tried every thing to make the thing go, and it did, but not like it should have with all the effort and money we put in. All the normal bottom end mods and these silly high comp pistons. Over size valves and rally cams, mild head porting and matching the intake manifolds. We also ditched the solex carbs for webbers and ran electronic ingnition.. We spent countless hours tuning with no real impressive results. If I were to build one today. I would use the 90mm or 92mm flat top to take it to 2.2lt and bring the comp up with a big head skim and thin head gasket. Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted March 11, 2013 Report Share Posted March 11, 2013 Ta for that then- I was just talking to Steve about 90mm pistons and then the smaller of the high comp options he's looking at. Dang, things are expensive for those motors! Listing the bits for a rebuild came to over $7000 ! I think we'll settle for less power for less money & make it torquey and reliable.

sebsta Posted April 29, 2013 Author Report Share Posted April 29, 2013 (edited) on sunday we took the beast for a run around the famous phillip island race track :) i was not driving it :( , as i was in the wrx :) the day started of very wet for the first 2 runs but dried out very quich which lead to some fun racing :P) the ra23 got a 2:16 lap time and i was only 10 seconds quicker in the wrx.... the car performed well but did get a little hot but nothing major went wrong :) now some arty shots TEQ , FTW!!!!!!! the mighty 18-rg :) photos from http://www.narraphotography.com.au/ and http://www.facebook.com/feralstephdesigner?fref=ts go check them out ;) Edited April 29, 2013 by sebsta Quote Link to comment Share on other sites More sharing options...
