Hey guys,

Got an RB26/30 and a big single turbo - the bonnet is so close to shutting but just wont shut!

What have you guys done to get around that?

Im trying to avoid spacers, was wondering if there's a carbon bonnet or whatever thats got great clearance?!?!

Cheers biggrin.gif

Can't you just trim the frame of the bonnet? Wouldn't that be enough?

I've seen pics of Jap drag cars that have completly removed the framing to save weight.

Were is it hitting? Timing belt cover or the turbo.
If you get a genuine c/f bonnet it doesn't have the support frame, as it is very strong/stiff on it's own. I have a full c/f bonnet made by Custom Carbon (currently not fitted to car and at the mechanic's w/shop), it consists or 3 layers of carbon and resin, that's it, no fibre-glass, etc.

Long time no speak!

lol, it was suggested by the mechanic and yeah - not a fan of the idea

Hitting turbo, im going to get prices on carbon over the next few days and if i go down that path (currently spacers is the go) ill spray it white to match

That must be a HIGH high mount manifold or is the turbo THAT big?

i dont know if anyone has thought of this, but any one thought of using LD28 engine mounts instead of hacking holes in bonnet subframes?

this was suggested from a retired mechanic who helped with my hilux rb30 conversion.

i think you will find the rattle and the crunch will dissapear if you have rices for breakfast instead of cornflakes, a snap crackle n pop from the exhaust is usually a good sign of a nice flowing exhaust, however in this case drop the gluten from the crankcase and run some thinner oil as obviously what is in there isnt protecting the mechanically moving bits on startup.

DIfferent mounts cant fix the problem, as the sump is about 4mm from the crossmember
