MRP 7a (aka 9age) Stroker Kit

After huge request we have designed a 7age/9age stroker kit (1900cc).
This will not be your generic stroker kit with bad rod/stroke ratios
(Others on the market use OEM style 4age pistons with shorter rods which brings the rod/stroke ratio down to 1.44 which is less than ideal in the modern world of building a good reliable engine!)

The pistons in this kit are a special custom design where we worked with CP to get what we needed.
Rod/stroke ratio is 1.52:1

Custom MRP 90mm Billet 4340 Crank based on the TRD/Atlantic Crank Design
8 Bolt to take 4age flywheels
OEM 4age journal sizes so you can use the OEM 4age size bearings
Oversize oil gallery holes which allows more oil to pass through the bearings
Oil gallery chamfer lead in/out which aids in flowing the oil in/out of the gallery holes
Oil gallery feeds are the same as the 4age crank meaning constant 360 degree of oil supply to the journals at all times unlike the 7afe crank.
Large counter weights to dampen harmonics at high RPM,
Dual crank sprocket keyway for those wanting to run this option.


Custom MRP Billet 4340 conrods with ARP 2000 bolts
Around 6% longer than the 7a rods
I-Beam & H-beam available
I-beam being the stronger but heavier of the 2 (These are like Argo Rods)
H-beam is similar to Eagle, Spool etc.
Rods are notched on the journals which acts as an oil squirter up into the bottom of the piston


Custom MRP Forged Pistons by CP
Low compression height, 20v & 16v available in both N/A & Turbo to any compression you require.

Rings & gudgens supplied

Power rating of the kit 800hp+ & 10,000rpm+
 

$3750NZD

 

Notes
Must be used with a 7afe block
No modifying of the block is required

If your fitting oil squirters into the block from a 4age engine and worried about clearance, the crank has been designed to clear the oil squirters.
Takes 4age flywheels

Have not settled on the maker but we are in talks with all those top brands (JE, Mahle, CP, Wiseco, Arias etc), basically who ever can give us the best price is who we will choose.

Cost is going to be around the $3kNZD mark for the kit.

Tentative on a 9ish:1 comp setup.... Mostly pending lead time.

$3k NZ is about $2400 AU right?

Comp ratio you can choose.

$3K NZD is an approx price!
But that equates to approx $2400AUD

How much power can you get from the kit? that depends on your supporting mods and its deigned to handle 800hp+

At what sort of level do blocks become an issue in 4AGEs?

I know a heap of engines have a horsepower/rev limit before torsional forces begin to crack blocks and basically rattle an engine apart.

Has anyone found that limit?

$2400 aud would be exceptionally cheap.
