E30 Zone

does you Arb tap/hit your exhaust manifold?

or is it fine one the car is on the ground - only problem while on axle stands?

I only got this when he car was in the air when I had my S50 manifold on the M52 in the touring.

But I think the pipes had been modified from standard too and they still touched with the suspension free to hand down.

mine touched whilst jacked up but when on the ground left me with a 1cm gap, didnt feel comfortable with it so i ended up using spacers on the arb mounts, now i have 3cm.
but some people dont have problems i did.

What exhaust manifold are you using? Never had a problem on mine - in the air or on the ground.

Mine looked like it would never clear the btb exhaust when it was up on a 4 arm ramp but cleared with no issues when on the ground!

S50 standard manifold

do you have a photo of your spacers?

Modified to fit the E30 I take it?

Mine was a btb one, which is basically a modified S50 manifold. Sounds like you might need to space the arb down a little to get the clearance if your manifolds weren't modified enough to clear them.

Just make a new ARB

LOL - E30 modified to take the S50 manifold!

Interesting.... get some pics up. That is a different approach to the conversion
It would also explain the manifold hitting the ARB I guess. You may struggle for advice as most conversions on here use modded manifolds, rather than completely standard ones with the car modded around them.

At a guess (without seeing pics), you'll probably have to space the ARB down.

Sorry no photos yet just seen this.

My car is lhd so helps with getting the manifold to fit.

Will post photos tomorrow

Ah, yup LHD definitely helps lol

That's exactly my approach:
-modify firewall
-modify subframe
-change ARB
-different lollypop

My car is also a LHD

I spaced the ARB down, modified the firewall and ran treehouse racing lollypops to clear the manifold, but the manifold sits too low so the bottom flanges will need cutting off and welding higher up, unless your car is mega high.

Which mounts are you using?

Sorry for the late reply, i used the traditional M5 mounts, modified to be stiffer.

no worries mine is almost done and finished now
am sure it will be too low but at the minute stardard is all I can afford!
