hi!

I´m interested to know if you guys have advanced technical know how about the Group a cars that was such a success in the 90 s. Its more and more popular to build a nice time attack car, and the "top secret" know how maybee not so top secret anymore??

I think it would be very nice to know more about hardcore technical solutions, data about suspension alighments, CG, RC, scrub, spring hardness, swaybars and so on, all this information would be alot help to people today trying to show the world about the GTRs splended performance.

i´m also interested in engine tech, such as the swing oil pickup in the wet sump and so on, all this Group a candy.. :P

I know there is a group a thread but its mostly just alot of talk about anything group a.

There was more than spring rates and swaybars mate.

There were underbody chassis mods and all sorts of business far as i am aware (as there certainly was with HR31's) :P

Not saying the Group A's weren't fast in their day, but given the technology and advancements of today, i cannot see why you couldn't realistically do a better job.

Tech has certainly moved on since then, and they of course were built to Group A rules, so I don't know why anyone would want to stiffle their build by replicating the specifications of them.

You could PM "Jetwreck" to request some specs and settings on the Group A GTR he is involved with.

while the cars were amazing in the day...things have come a long way in 20 years.

the group a cars had custom hubs and control arms for a start....very little was standard.

I have seen the alignment specs and they were not far from what most people would already choose. eg not a heap of camber or toe out. remember they were pretty heavy and tyres were not huge.

Be interested to see engine spec. From what i can find on the net about j- groupa was that they were limited to 500ps. And std displacment. Did they just run n1 turbos?

bit more HP than that(the GIO car dyno'd recently at 360AWKW's on 1.5bar).....they also chased torque more that HP with them.

How was the response like compared to say a set of -9's which are around the ballpark for that power?

You could say -5's but they are closer to 400 @ the tyres.

:P ....wtf are you talking about!.....lol

sorry man you lost me...elaborate please!

Garrett bolt on replacemt turbos (2860's), new tech stuff :)

Was wondering how they compared response wise. Obviously they would be better given 15 years of dev.

But just how much, and more importantly how do the torque curves differ

Even get the two cars onto the dyno same day just to see it all.

Would be an interesting comparison IMO, results could surprise everyone :)

oh....I get yah now....remember I'm only a "Spacer".

The turbo's on the motor came with the motor.....when we rebuild the ones on the current motor I'll let you know what's in em....oh and we wont be changing the spec....no need they do the job pretty effectively!

      Question about BoV on RB25DET NEO

      By Murray_Calavera · Posted

      You've just discovered a really good reason to tell yourself, yes, I do need to buy an aftermarket ECU. Put the MAF in the bin. Slap in the new ECU and have a think about what turbo sounds you prefer.  Do you want a 90's style BOV wooosh? Do you want a hektik tsututututu?  Mate, can't go wrong. Just gotta get that ECU and the world is your oyster.

      Question about BoV on RB25DET NEO

      By Kapr · Posted

      Hi. Iam just curisou about this topic. I saw this video. It is about Greddy Type FV2. I know that BoVs are about that sound but how and when to use it? I read some topic here and from what i have understand on stock RB with MAF there will be some "problems" if you use this BoV? It vents the air in to the atmosphere and the MAF on stock car needs this air back in to the intake and not out? Or is it wrong? If so...i saw you can put some adaptor to circule air back...but does that not "loose" that sound? I saw another BoV from Turbosmart and it has two "exhaust" like ports? One is for the stock tubing for letting air back and one is for "sound" and let the air in the atmosphere? Can someone please explain? This is the Greddy one:  And this is the Turbosmart.     THANK YOU!! EDIT: So i read about this topic some more and i if i understand that correctly: That Greddy can function either like BoV or 100% Bypass valve? And that Turbosmart is what they called hybrid so you can adjust what and how many air can be vented out or back in? Is this right? THX!

      Low oil pressure after WOT

      That dirty voltage drop is the culprit I suspect

      The Ls1 R33 Of Fury

      It's about time I start work on my sun tan. So I knocked up a few parts that will all combine together to become my new power steering reservoir. Now just to produce an abundance of UV and IR rays while melting a heap of bits of alu to become one... Well, that's after I put one more hole in it for the return line to plumb to. It likely won't be this weekend, as Sunday I'm meant to be in doing some last minute stuff to the AMG race car, and the weekend after will be filled with non my Skyline stuff, followed by Bathurst 6 hour. So I don't expect to get to melt metal for at least 3 weeks.   I also managed to stuff up and start cutting the hole for the res to pump pipe on the wrong side of the line... It means instead of the lines being nice and tight against the inner guard, they'll be out off the guard.    The size of it means I should end up with about 1.8L of power steering fluid, and still have space for another half a litre before it reaches the overflow/breather. This is wayyyyyyy more capacity than factory, which should help keep Powersteer oil temps lower, and the design hopefully allows it to prevent any aerated oil being able to makes its way down to the bottom as it'll have a couple of baffles and some hopeful trickery to force air bubbles away from the bottom.
