Hi Paul. 100 octane and high compression would definitely make a difference. Getting 400 bhp from a 3.8 liter engine running the GE80 cam without some magic or a happy dyno IMHO would definitely need some help. Those magic ingredients might do it but I concur with you a 100 octane engine is a nuisance in NZ especially since race fuel has now gone E85 etc

With regards the Targa Tour we stopped off twice a day at pre designated 98 pumps. These were mapped into the route form day 1 and so we never had to top up with an ethonol blend or anything lower than "98" (actually crap quality 97 min octane as its mostly is in NZ these days) which was much relief especially for the guys with modified engines...

Hi Tim. Mine are "non name" bucket seats from Taiwan form the company that make Bride racing seats (for the drifters amongst us that may recognize that brand LOL!). I wanted to try a recaro style seat but wasnt sure myself or my wife would like them for long journeys. We both ended up loving them. I had them custom made in Carbon fiber and sourced and sent them the classic grey leather myself. All up they cost me 1000 GBP for the pair including freight and sliders and side mounts! I bought an extra set of custom Alcantera cushions (thicker for the passenger side). They suit a taller driver (6'+) as they are high backed and ok for a 200 pounder. I thought for that money they would be crap but they are actually pretty good hand havent broken yet on track or Targa. They are not FIA however (although they do make an FIA version which was a little more expensive). It was an experiment but now I like them Im to replace them with Recaro Pole position. Ill probably buy them the cheapest I can in perlon from the US for $800 each and have them recovered in NZ in leather and alcantera. I need the FIA for historic rally in UK & Europe when I head over there one day....

PS. The ABE version looks fine. I understood it was better as it was FIA & TUV so can be used legally on street and track in europe...

Thanks for the info Macca. The Porscheshop has their own brand, EuroCupGT, which are carbo seats available in leather for around half the price of leather PPs:

They have a silver (aluminium?) section for the shoulder straps rather than being completely black which I think makes them look a little tacky.

I think I saw somewhere that the ABEs are not FIA approved but by the same token the FIA seats are not TUV/ABE approved & are therefore not strictly speaking road legal. Not that I've ever heard of anyone being penalised for using FIA-approved seats/belts on the road.

That RSR build is definitely a car to consider. I have looked at it on the internet on and off for a while. Pretty close to full competition car though road reg. Can't imagine driving it to work. But at that ask and a deal to be had its good value. can't build it for anywhere near that price.
I reckon what we need is Sponsorship to run cars like that!!

May be the better deal is also the smaller motor? Need to check rules but a car like that needs to be able to run in Historic events to get the best use and most fun. Like in Europe?

Macca

Tim. I think you are right. The ABE isn't FIA. Seems a bit pointless to make them one but not the other!

The UK copy 997 race buckets do look tacky.

Here are some pictures from my supplier of their SP1 and SP5 seats. The SP1 is in a 964 driven in Singapore by a 6'4" dutch guy and he manages just fine. Maybe you should consider something like this. You could land black leather ones in the uk for around 800 gbp the pair with all the hardware!

Interesting comment re 100 octane fuel

so can somebody tell me if a 10.5 compression motor twin plug 2.8 to 3.0 MFI is going to be happy on our 97 pump gas

Macca

Graeme. 10.5 isn't aggressive and should work fine on pump 97....

gt38088

one more thing - say target 280 hp - possible on 97 gas?

kiwi 911

Twin plug - yes.

From my limited understanding, single plug max on old motor is 10.1.1 on 95 pump, 10.5 on 98 pump and an engine rebuild every few years. Twin Plugging - the sky and your budget is the limit.

kiwi 911

Yes - easy - give Jon Warring a chq for $35K and a good donor SC engine or C3/3.0T case (if you can find one).

You will get PMO (or MFI if you can find all the bits - better add another $10K), 3.2 short stroke, twin plug, EFI, and compression of around 10.5. Jon has built a few of these motors. I have seen a copy of this motor build by Jon in the flesh and was told by the owner he dynoed at 275hp. The engine is currently in a 69T with broken head stud.

Thanks for posting those pictures Macca. Those seats look sweet, fully carbon (the PPs are GRP & the carbon PPs cost twice as much again for a 2.5 kg saving per seat!), black leather all over - nothing ostentatious or tasteless.

It's easy to lose your shirt on seats! ...but then they're kinda important - beats an apple crate!

yes indeed "the sky and $"
haha we need a motto as well as a name for this gruppe

With money anything is possible! The factory got 99.79 bhp/litre out of that capacity back in 1974 with the 2.8RSR so given improvements in ignition and experience in engine building techniques I cant see why a 280 bhp 2.8 MFI isnt possible and Im pretty sure they are being built. Compression was only 10.3 for the 2.8 RSR. I assume it was twin plug. They got to 110 bhp/litre for 3.0 RSR which is incredible even in modern times. Both these engines were lifed between 40-60 race hours and of course back in the day ran on 100+ octane leaded. Ive seen the ex Hamiltons one in Oz running and it runs like a hairy dog anything less than 3500 rpm so not a street car (cams).

However with modern engine management, some PMOs or similar ITBs and some other modern accouterments I dont think it would be a stretch. With a strong bottom end youd have it revving to 8000 rpm. But IMHO to build such an engine properly with tuning for the road would be a 40k usd+ job and Im not sure there's anyone in NZ that could do it properly...

Macca

Tim would you believe that those seats including Carbon, leather in black shipped by air and including bracket and sliders cost only $750 USD each! Mine were $1456 USD landed at the time (plus the cost of the custom leather for me). They could be a little more now....
