Is It Too High?

[murrayis]

Well...

I just bolted my stainless manifold onto my rb24DET then bolted my Garrett T04Z ontop of that... But I don't know if its going to fit under the bonnet?

What do you think?

I don't have an engine in the car at the moment or a bonnet on it to measure it, but from the top side of the hole in the engine mount to the top of the turbo is 470mm or 47cm's

Advice Please....

This isn't a definitive answer, but I just checked from the top of my cam cover to the top of my stock BOV it is 13 cm's. However, I think where your turbo sits the bonnet may angle downwards and reduce the gap more.

If you haven't cut up your standard intake manifold, bolt it on and see where the turbo sits in relation to the throttlebody/crossover pipe...

As above - use the old cross over as a reference.

Its gonna be tight either way, also consider a heat shield etc otherwise the heat is going to do some nasty things to the paintwork on the bonnet

[murrayis]

yep, was thinking of doing that.

Also was going to put some sort of flame/heat retardent underneath the bonnet and put a beanie on it.

Jeez that thing is sitting high. It looks about 3 quarters of the turbo is above the rocker covers.

I have a photo of my 42R which sits about halfway to my rocker covers and it just fits under the bonnet although I had to grind down part of the knob on the front cover and a 26/30 sits a bit higher.

I think you will find judging against mine that it just fits but will sit against the underbonnet heat shielding.

[murrayis]

Hopefully it will fit, the botten is a Fibreglass job so will definetly have to put a deanie on the turbo and some sort of heat proofing on the underside of the bonnet, where do i get that "flame guard" tape from? or wrap?

make a hump in the hood or cut it out is looks good

[joeyjoejoejuniorshabadoo]

dood that is HUGE!

cops will never find that one

cut a hole in the bonnet

[murrayis]

I won't be cutting any holes in the bonnet, Can somsone measure the distance from the bolt in the passenger side engine mount to the under side of the bonnet if possible?

Out of curiousity whats the legalities of having the turbo half way through the bonnet lol

[l0WRB]

as far as i know its illegal? lol a pedestrian off the street could burn themselves on that front cover.. some bullshit excuse they make up anyway.

[-_-StRyDeR-_-]

could suck native wildlife in Cameron!! lol. gs think of the greenies...

haha ok back on track, looks the goods, im having trouble trying to measure up for a 42r under my bonnet!!

[murrayis]

Where can I get that flame guard wrap or sheet to wrap the oil and water lines and plus on the underside of the bonnet

[Beer Baron]

yes it's illegal to cut a hole in the bonnet, it's illegal to have something sticking up through the bonnet and it's even illegal to have something like that right up close, or even hard against the bonet. there is supposed to be empty space between bonnet and anything hard so that when you drill a pedestrian at 50kmh and they land on your bonnet, the bonnet can crumple before it hits anything hard. could be tough to get around these things.

[murrayis]

Its looking like there will be about a 3cm gap between the turbo and the bonnet, having a ADR approved bonnet i'm not just going to go chop it up

[candy33]

To me it doesn't look like it will fit. I got exactly the same turbo but on an rb26 and it just clears the bonnet, and nowhere near as high as yours.

[cactus]

Cut the exhaust manifold, and flatten it out so its on such an angle towards the engine, make it so the flange is nearly flat. thats what i had to do to mine, you will pick up a lot of clearance and its not that big a job.

[murrayis]

The problem with that is it wont clear the strut tower, its about 30mm higher than the manifold because theres an adapter on the manifold to go from t3 to t4

[nizmonut]

hmm rb24? stroked bored rb20 block? can't really help you there. have to find some one with the same hieght block.
