RS Motorsport :: Classic Speed Restored

This Mk1 has been undergoing a bare metal nut and bolt rebuild with the aim of fitting a 2.3l YBP turbo engine.

As it sits in the picture is has;

Hilux/Hiace diff with Detroit TruTrak centre 3.7:1 ratio
1 piece tailshaft with XR8 uni's
W58 Supra 5 spd box with Dellow bellhousing
Saab 9000 Concentric clutch release on a Sachs 8" twin organic plate clutch and steel flywheel

Front suspension is 2.8i Capri bilstein, 220lb springs, caster adjustable 22mm Kmac bar and caster maximised antidive sway bar mountings. The cross member is world cup style.

The rear sits on reverse rolled and re-profiled single leaf springs, controlled by billies. RS anti tramp radius arms are in place.

Stopping is provided by a low flex adjustable pedal box feeding 2.8i front calipers and 20mm vented disks, and R31 skyline rear calipers and discs. Fronts are being revised for 295x25mm discs with 4 pot alloy calipers.

Wheels are Simmons 15x7.

Instruments are Twin cam 6 dial and siwtchgear is a mix of Mk1 & 2. RS seats avoid the use of drums.

The YBP engine is a work in progress. The bottom end uses an 88mm billet crank, forged steel rods and forged pistons. The head is where development is presently focused, the aim being to get a complementary combination of manifolds, ports, cams and turbo. None of which are likely to resemble the factory cosworth pieces in any dimension. Under consideration is a variable inlet manifold configuration. Motec management would appear to be most suited because of software functionality and I/O capacity.

Mate, that is the bench mark to where i hope to one day scale a 7.
You should call that car Cindy, coz it's a straight out Super Model.

that looks geat mate

200mph,

Thank you for your thumbs up. Be patient and keep at it, and you will suceed.

Cindy haye, I'm hoping Angelina is more fitting.

Michael_1,

Great to here it is not just my biased opinion.

John,

You posted this pic while I was away, just round to seeing it. Car looks fantastic.
What disks did you use with the Hilux diff? I just picked up a Hilux diff for my current project and was looking at using the R31 calipers. I need to keep a mechanical handbrake and these look like a good setup. If you have any pics that would be great.

Bruce,

Thankyou for your approval.

I've used R31 Skyline disc as well as calipers.

I purchased undrilled (stud holes) DBA rotors from the local Autobahn. To obtain the undrilled version simply add the suffix U to the DBA part number.

I chose to have integral bearing housing / caliper mounts made to suit.

It is possible to use a cutout plate with the original bearing housing. The thinner plate alternative would provide less resistance to offset torque and maybe show up as tapered pad wear or pad knock off effect.

The mechanical handbrake is very progressive and works nicely. Initially I had the standard handbrake lever connected to the R31 caliper handbrake cables by a rod with clevi each end. My test of it around the local skid pan made me think it is a little heavy, so I am going to double the leverage. Lever travel was very short so no issue with running out of travel.

Michael,

You'll have to set it as wall paper on your computer.

Bruce,

13's are a squeeze on mine, could come down to brand of wheel.

The discs have sufficient surface width to position the caliper closer to the centre. I positioned them on mine more toward the outer for maximum brakes.

I used a Hiace housing for mine to minimise weight. The hiace housing had to be shortened, but it contains RN25 hilux axles which are the right width.

Thanks for the +ve feedback fella's.

Hi John,

Hope you dont mind me dragging up this old post

If you made a spare front spoiler what sort of money would you want for it

Regards
