21 Turbo Back in the 21 Turbo Family after a 9 year break!

Bought a 21 Turbo at the weekend, always had one on the fleet between 1996 and 2005 but none since. Its a project but has so many good bits on it I couldn't say no for the money :0). Needs turrets welded and new sills. Haven't heard engine running but previous owner was very genuine and said he had it running recently but the fuel lines are blocked where it has stood for a few years. Has full photographic and receipt history with 15 K of bills!

Engine spec is particularly interesting.

Kent F528 cam 1600-6500. NGK VX spark plugs. MD80S stage 4 Hybrid Turbo Dynamics turbo running 22psi max boost which has since been rebuilt with larger compressor wheel, compressor and turbine housing with opened up throats in the turbo to increase A/R. In car boost controller and boost gauge. Prima Racing Re-Programmed ECU with ‘hot shoe’ to allow chip replacement / mapping when rolling roaded. Scorpion single tail pipe stainless exhaust system with custom centre box removal. Modified MD97 Prima Racing Head with enlarged/matched ports to inlet/exhaust manifolds. Custom fabricated stainless steel tubular manifold, new pistons balanced with liners (individually and as set with (new) rings and rods). 360bhp max flow K&N cone filter. Milled out throttle body to 60mm to allow increased air flow. Samco silicone boost and some coolant hoses. Large front mount intercooler. Prima twin piston atmospheric ‘dump’ valve. Adjustable Cosworth fuel pressure regulator with gauge. Silkolene Pro R 15W-50 racing oil as specified by Turbo Dynamics for their hybrid turbo. Spal cooling fans. K&N breather.

Should be good when going, although the turbo sounds a bit big and therefore laggy. No power claims made, what do people reckon? Going to put some decent brakes suspension and tyres on and maybe a smaller turbo and use it for track days next year :0).

Which leads me to the questions what is available in the way of brake upgrades and what suspension parts are available?

Does anybody know what the chassis numbers run to, figure this must be one of the last 2wds made, never seen a K plate 2 wd

Andy Oakwoods car was a K, and I bought one to break from Geoff Histead many moons ago.

Brakes, HiSpec do a big brake kit.
Suspension, Gaz do a full set :)

Welcome back to the fold!
 
Oh and power wise i'd say between 220 and 240-ish. Thats about the usual level for something like that without a standalone ECU.
 
220ish, is that all, my old ones used to make nearly that just by running 16-17 psi boost with an exhaust and an air filter. I need to check the injectors don't I, standard ones only flow for about 220 BHP at standard fuel pressure if I remember rightly, should give Prima a ring really and find out about that chip.

Once you get up toward 250 and low twenties of boost you'll struggle with valve float...it wont go much more than that without new springs.
 
Would the cam / head combo from prima come with uprated springs?
I've never seen one that has bud. In fact all the Prima engines i've come across have been way under the quoted/claimed power, most notably Rob Coulsons blue one....280-300hp they told him. It rollered at 197 lol
 
Piper now sell valve springs to suit - 60lb stronger. Ask for Adam when ordering as he sold me mine. If I ever get to the boxes to find a receipt I'll post the part number.

Hi Spec for brakes, I'm using the 'race' 6 pots, very slim caliper. Others use the Monster 4.

I got the HiSpec Billet 4's on mine, with yellow stuff pads and Clio V6 330mm discs (direct fit!) with custom hangers I made myself. Cost half the kit price, though a little more work.

I'll buy them off the shelf as if I try and fabricate hangers I'll probably end up hanging myself :0).
