One of our local Racing Fabricator shops acquired ALL of Nissan's Factory Infinity IRL engines and hardware. I can't tell you the details, but this was part of a " Reward " for ending Toyota's GT3 domination at the SCCA Runoffs in 2003.

These would be 3.5 liter and 4.0 liter normally aspirated V8's. Designed to run on Methanol, but could be adapted to Ethanol or Petrol. New and used engines available as well as new and used hardware. Note: Electronics and ECU's are now available!!

Would be excellant for a Hillclimb car, EuroBoss or Sports Racer. If you're already running one of these engines then this would be the place to find spare hardware.

""One of our local Racing Fabricator shops acquired ALL of Nissan's Infinity IRL engines and hardware""

does anyone know where the northstar/olds/[chevy?] gm IRL motors went
did anyother class allow their race use

why ? a hot rod project/ auto-X car
I would love to find ported heads, wild cams, intakes manafolds, FI units, cranks rods pistons ect
and programable CPU
and other bits if surplus priced as unuseable in any current race class

so where did they go??

I have 4 northstars that could use go fast goodies
from even little bits like head studs to complete motors
or even bad/blown motors to strip some parts off

they will be used in mid-eng sports cars for auto-X

CHEVROLET IRL V8 ENGINE

2002 SEASON

Available in limited quantity, these 2002 season Indy Racing League engines have been re-configured for street use by Ryan Falconer. Using special camshaft profiles and reduced compression ratios, these thoroughbred racing engines now create 560 horsepower with Eaton 112 supercharging and MoTeC fuel injection. All engines have logged miles during the 2002 Indycar season for qualifying or racing and have verifiable pedigrees.

DISPLACEMENT 214 cubic inches - 3.5 liter
BORE 3.660” - 92.964mm
STROKE 2.534” - 64.364mm
MAX HORSEPOWER 560 @ 8,000 rpm
PEAK TORQUE 421 @ 5,500 rpm
ENGINE WEIGHT 340-pounds (154.20 kg)
490-pound (222.26 kg) engine & transmission

INDUCTION Ryan Falconer Racing Engines intake manifold
Eaton 112 supercharger
Water-to-air intercooler
Drive-by-wire throttle
FUEL SYSTEM MoTeC engine management
FUEL REQUIREMENT 91-octane street fuel
OIL SYSTEM Dry sump with Dailey Engineering pump

What on earth do they need a 200amp alternator for?

To run the electric fuel pump.

There were around 500 manufactured, so they are around. Pretty cheap too (though that depends on your definition of cheap). A buddy of mine just took moved into a shop in Indy and found four in the loft, still in their crates. If you are willing to scrounge around, you could probably assemble one pretty cheap from parts. However, not one part will fit a production Northstar or vice versa.

[Chickenman]

The engines Infinity IRL engines from Specialty are a LOT cheaper than the Falconer units...and they are complete. I can't say how cheap....but a ding danged bargooon in comparison to the Falconer units.

Electronics and ECU's are now available.

you say no thing fits
didnot expect it to be eazys or quick
but thought they were production based sorta
but thicker blocks and heads with bigger ports valves ect
that a little hotrod teck could adpt to the street motors

is the bellhouseing bolt patern the same as the northstar ie common GM frontdrive
port spaceing the same?? so shims could be used to get the manifolds on??
spacing of cam lobes and bearing diamaters changed?
some thing maybe adptable even if difficult

btw what happend to the 4 crate motors in the loft??

[ray b]

is the 2002 chevy badged motor ever northstar/olds based
or an english build custom race motor
sorry realy didnot follow IRL that closely

what about the first few years 4.0 L units are they any closer to the northstar/olds street units??/

[Wuzak]

I think that in the early years of the IRL the engines were constrained by production engine dimensions. ie bore space, deck heights, etc, had to be the same as for a production unit. For the last few years they all have had to conform to the same dimensional limits. The 2002 Chevy would, I have little doubt, be a custom built engine.

Also, wasn't the 2003 Chevy designed by (then) Ford-owned Cosworth, and the Honda engine was designed and built by Ilmor?

[ray b]

Wuzak
I would rather find an early olds 4.0 motor
then the later chevy 3.5
even in a worenout or blown unit
if they canbe used with northstar street parts

and was unsure when the Ford built by Cosworth "chevys" started production
wonder how much DFV teck was in that " chevy" as the last version was 3.5 too

[McGuire]

The GM IRL engine was the same unit from 1997 on, except for the 2003 engine which proved to be a turkey and was quickly replaced by the Cosworth-supplied engine still in use now. (Wonder if any of those guys have come out of their cubicles yet.) In 2002 the engine was rebadged from Oldsmobile-Aurora to Chevrolet and got new cylinder heads, front cover and other pieces (which had been developed earlier but not distributed as there was effectively no competition for awhile). Not everyone used these pieces in 2002: Penske/Ilmor continued to develop the old cylinder head with considerable success.

Over 500 of these engines (or the blocks and component kits to build them) were manufactured, and all their parts interchange nicely. The 4.0 used a 90 degree crank, while the 3.5 version used a flat crank...except there were a number of engines using 90 degree cranks the first year of the 3.5 formula. With the flat crank the roller cam chain was replaced with a link belt to fight off torsional vibration issues. There were also some engines with tiny main and rod bearings etc. built looking for lower frictional losses. The Cadillac LeMans deal was the IRL engine with twin turbos hung on it; how about one of those hmmm. All these parts and pieces interchange with each other in ala carte hot rod style more or less...provided you know what you have and what you are doing I suppose.

However, the IRL engine is roughly speaking a "sillhouette motor": while it resembles a production Northstar, it is actually smaller in every exterior dimension and none of the parts interchange. GM and the IRL did an excellent job of selling the engine as "production-based," which I suppose it was given the elasticity of that term.

Before the IRL engine, there was an Oldsmobile IMSA road racing version of the Northstar which was a sort of middle step. Some of those parts may fit a production Northstar, but I don't know that or which and these pieces would have to be pretty rare by now. There aren't a lot of aftermarket parts available for the production Northstar V8 either, probably due to the difficulties in converting its somewhat goofy accessory layout to a North/South RWD application. (the water pump drives off the LR cam cover, the intake is backward, etc.) I have done it and it's not a lot of fun, nor does it produce a very aesthetically pleasing package when all is said and done, say for a street rod or similar application. To me the race engine would be the way to go, provided it fits the budget.

Hmmmm...one could find out who supplied the pistons and camshafts to McLaren (of Detroit, which developed that engine) and there are your sources for low-compression pistons and cams designed for gasoline and road racing, for adapting the IRL engine for road use.
