Title: 186 engine mod
Post by: Jonno on March 20, 2003, 10:34:14 AM
Hi everyone,

Please excuse my ignorance here?I?m rather new to the modifications thing.  I?ve just bought a ute which has a 186 engine fitted.  However, the clearances seem very small especially with the extractors on the passenger side (about 5mm?.see arrow in photo).  Also the engine is considerably lower (3 inch) at the rear than at the front.  Probably just being paranoid here but are these alignments typical for this mod?

Jon,

What gearbox are you using?

Maybe the extractors are for something with more width between the chassis rails - HT/K/G ?

Hi Craig,

Its a 3 speed all-synchro box, floor shift.  Still finding my way around though..only had the car a few weeks.

Hi Jon,
Extractors are not the normal early Holden type. You might have hassles with roadworthy guys being that close to the chassis.
The engine angle is determined by the carby needing to be level. Easy way to check is with a spirit level in both directions across the top of the carby. Doesn't have to be spot on but the closer the better.
Where the engine mounts have been welded on the crossmember and the rear gearbox mounts are positioned is about the only way of adjusting that.

thanks Leigh,

the roadworthy is what's concerning me most at the moment.  I think you're right, the extractors will have to go - i'll have to find some others.  The carbie is not dead-level, but not too bad.

all you need to do is heat with an oxy and using a big crow bar or similar bend it over a bit using the chassis rail as lever point,as it is only about quarter of an inch too close

Jon,

Save your cash and buy some new FC extractors. If you close to Sydney you could also try Slim on 0402 465768. He may have some good second hand ones.

When you modify a car its worth the expense to do it right because otherwise the car just becomes an unreliable and pigheaded pain in the arse. You already own a car that someone has taken shortcuts with by not using the right part so don't fall into the same trap.

Why don't you join one of the state clubs? You said that this is your first experience with a modified car. At least go to a meeting and check it out - I think you'll find it very useful.

Hope the car turns out OK.

Cheers,

Craig.

thanks Craig,

will certainly join the local club, was just hoping to get the car roadworthy first (but maybe this is the wrong way around).

cheers, Jon

I have found that the best and cheapest exhaust set up to use on a red motor/early Holden combo is to use the cast iron headers from an X2, 186S or GTR Torana and use the factory 186S front pipes.

hi jon
I think your extractors are to suit a later model with a traumatic trans, the auto is wider than the manual box, also the hot air pick up point is visable in your photo so they are to suit something with anti polution crap, depending on how handy you are buy some exhaust tube and a slab then cut the pipes to achieve the clearance and re weld.

Re angle of the engine - check to ensure you have you rubber mount inbetween the gear box and crossmember.

Re exhaust clearance - pace maker make extractors to suit an FE/FC with a red.  Mine cost me approx $350 including fitting.

Sorry about the delay in answering.  Things have been busy!!

Thats the one.  If the carby still isn't level, undo your nuts and jack the gear box up.  I'll think you will find you hit the floor pan before you get any real improvement to the engine angle.  You will then have to decide if it's close enough or if you want to mod the hump
