V8 RX7's

[Turbo T]

Is there a UK forum/registry for V8 powered RX7's guys?

Apparently it helps the car's cooling issues in hot climates. I knew a guy who raced in the Silver State Classic and he swore by the small block Rexes. Reckoned it didn't muller the handling too badly either.

yeah been doing a bit of reading, looks like a nice swap.

yeah thanks mate I have seen those, just wondered if there was a specific forum someone had stumbled across.

Not a huge amount over on MRC - strangely enough it's not that popular over here unlike the US. There are a few guys though and FDUK is more likely to have some info as it's FD not rotary...

[Turbo T]

Thanks for that.

whats the lowest weight possible to get a stripped FD3 down too?

Not sure Just removing the back serats and reare intoerior, spare wheel etc saves a bit over 50kg. going for lightweight seats, losing the rest of the interior, stripping all but essential dash bits, losing sound deadening would probably be another 100kg.

Lose the aircon, mechanical water pump, air pump (emissions) and cat would be another 25-30kg.

Losing 200kg wouldn't be too hard so a 3rd gen could easily be about 1050-1075kg.

Get serious and replace the bonnet with c/f, rear hatch with fibreglass and go laxan for the side windows and rear hatch glass and you're talking early 1000kgs I suspect.

Add roll-cage and fire gubbins and you're back to maybe 1025kg...

Hard work would maybe get it down to 1000kg. That'd be handy running ~400rwhp wouldn't it?

It's not a unique thought

Was at the GT Battle on sunday helping out (immoral support mainly) some mates running their rexes and it was clear that the weight penalty of heavier cars was huge in terms of time. The Dax's were pasted for power but corner speed was huge...

Ive stripped the car down, removed unessential items from under the bonnet etc, but my corner weights have the car at 1100kgs. I have kept the glass though, whereas Giles at Brunswick have replaced the rear and side windows and saved a further 25kgs.

If I was to do it again, I would strip down to bare chassis and getting the chassis dipped. The sound deadening weighs a ton! But is horrid to pull out!

We've now over 400bhp so almost 400 per ton

oh bet thats nice.

Did you remove the PAS, AC etc to get to 1100kg's.

FYI there is a guy who will shot blast the shell back to bare metal and then Zinc primer for around £400. We just used him on a MK1 RS2000 my friend is building. Let me know if you want the contact details.
