Default Gruppe-S lightened crank pulley $89! Stage 2 Plus Engine($2799)/sti bigport Heads

Hey guys,

INTRODUCING the Gruppe-S Lightened Crank Pulley!
-1.46 Lb
-Almost 4 lbs lighter than stock!
-Better Engine Reponse!
-Allows for quicker shifting!



Normal Price: $109.00
SPECIAL INTRODUCTORY PRICE: $89.00 Shipped!
Need Belts? Combo with PE Super Timing Belt: $239 Shipped!

Got lots of engine goodies!

GRUPPE-S STAGE 2 PLUS SHORT BLOCK
This engine is the ultimate forged short block available without sleeving. The GS650 PLUS starts life as a regular STI shortblock. First we replace the weak hyper-cast stock pistons with custom spec forged units (race coated). Not only are the pistons significantly stronger than the stock units the pistons are substantially lighter too. We then address the connecting rods. The rods are replaced with Helix +2mm forged H-beam rods held together with ARP L-19 bolts. The super-strong forged rods coupled with the best rod bolts available on the market allow for high RPM operation. The crankshaft is then modified with our proprietary techniques creating a crankshaft similar to the $2000 STI race crankshaft used on the WRC cars. The bearings are swapped out in favor of Gruppe-S coated race bearings. This addresses all the common main failure points of the stock STI 2.5 engine – spun bearings, cracked pistons, and damaged rods. FOR MORE INFO: http://www.gruppe-s.com/Subaru/submotors/GS650SB.htm

FEATURES
*Gruppe-S / Wiseco Custom Forged Pistons
*Gruppe-S Detonation Resistant piston coating
*+2mm Long Rod Ratio Design
*Coated High Performance Rod & Crankshaft bearings
*Helix +2mm Forged Connecting Rods with ARP L19 Rodbolts
*Reworked high RPM crankshaft (Nitrided & Cross-Drilled)
*Professionally balanced and assembled
*Capable of up to 650HP Operation

WHY LONG ROD RATIO?

*Longer rods reduce stress on bearings, wrist pins, rod bolts at TDC allowing for higher RPM operation
*Longer rods delay combustion timing thus reducing risk of detonation
*Longer rods improve air flow characteristics at higher RPMs

$2799 + core!!!* (ONE AT THIS PRICE)
*Core charge is $500 and will be refunded upon receipt of a good working core (low compression is ok, cracked / scored cylinder walls is not).


EJ22 FULLY FORGED CLOSED DECK SHORT BLOCK!!!
*Gruppe-S / Wiseco Custom Forged Pistons
*Coated High Performance Rod & Crankshaft bearings
*Helix Forged Connecting Rods
*Professionally balanced and assembled
*Closed deck design for high boost applications
$1999 + Shipping (ONE AT THIS PRICE)


STI >BIG PORT< HEADS
Guys, these are the ULTIMATE heads for the EJ20. These ports are bigger than the USDM WRX, and even bigger than the JDM or USDM STI!!! That's right they are bigger than the 2.5 STI heads.

These heads are found on the late model Limited Edition Legacy STI, with its 280HP and 8000RPM engine, these heads feature the latest innovations in performance heads including a high performance valvetrain, shimless buckets, and hollow cored cams. These are twin avcs heads, but we have taken the liberty of deleting the exhaust side AVCS so you can run either single AVCS or none. We recommend STI exhaust cam gears to be used. This setup will rev to 8500RPM!

Excellent for the modified 2.0 car.

These heads are used for about 10,000 miles and need to be redecked and valvelash reset before use. Exhaust side AVCS has been deleted!

Cam gears not included

$999 Shipped!! (ONE AT THIS PRICE)




2006 STI EJ20 COMPLETE LONG BLOCK
This engine is pulled from the JDM 2005 Subaru Legacy STI 2.0. This is a GREAT ENGINE. The head ports are HUGE. They are even bigger than the USDM STI head ports. The cams / heads / valvetrain is far superior to the JDM V8 STI engines. The shortblock has forged internals, but it an open deck block.

This is an engine rated at 280 HP and is a single turbo engine (not the twin turbo one of the previous generation). Features include TWIN AVCS, larger duration camshafts (STI "press on lobe" style), better flowing heads, semi-closed deck, and forged internals. This engine is very similar to the JDM STI 2.0 engine. You can opt to leave AVCS unconnected, run a JDM ECU for twin AVCS (you will need the pedal box and gauge cluster for hte DBW t-body) or you can pop out the cams and run WRX or STI cams.

We originally thought this engine had low compression but as it turns out it had some debris on the intake valve on #1. After some carb cleaner compression is now over 90% across the board.

This motor is extremely rare and hard to find (only 400 of these cars produced) and is handbuilt in Japan. Side feed injectors not included (available for $100). Engine is as shown.

$1999 + Shipping!! ONE AT THIS PRICE!


LONG ROD RATIO SETUP KIT
-Custom Wiseco +2mm Pistons
-Aerospace coating to reduce detonation and improve thermal characteristics (same as Cobb)
-Helix +2mm rods with ARP L19
-Longer piston dwell time improves rev range and top-end power
-Gruppe-S Coated Race Bearings
$949 Shipped!!

The USDM STI heads are not an optimal setup for the EJ22 because the dish area of the heads are so large. I believe it can work but I would not recommend it . If you're thinking EJ22, I would consider our JDM STI Big Port heads, these would be perfect for the EJ22 - offering the flow and the revs for the high boost that the EJ22 can sustain.

Thanks,

Gary

But how will the compressionratio be with the heads, either the WRX heads or your ported heads?
If you would port the heads, you will get a lower comp.ratio and I believe it will be 7.3 or 7.5:1 with stock WRX heads... thatīs quite low down, donīt you think?!
Please let me know!

Austria Impreza - the dish area on the JDM STI 2.0 heads are actually a bit smaller than the WRX, so you'll bump up your compression a bit but not a whole lot. If you are worried about high compression (low octane gas only) then you can run a thicker head gasket to keep compression inline.

MK3Design - Yup stock dimensions - not underdriven, just lighter!

Thanks,

Gary

Default 2.2 shortblock

Thanks for the answer Gary!
I do not worry about compression if it is quite near the stock 8.0:1 ratio, but I would think the comp.ratio with the 2.2 shortblock and WRX heads will be around 7.3 or 7.5:1 and I do not know if this is any good for me.
Okay I might be able to run more boost, but how does this feel down below the rpm...
I wanted to keep my heads as my engine has only 48.000km done...
What gasket could be best for this combo?

Many thanks for your help!
And I want to let you know, that Iīm in touch with Max!

Hi again,

which pistons did you use on your built engine?

Wiseco EJ22 pistons

K601M975 .020 overbore 97.50/3.838 height 23 Comp.ratio 8.5:1

K601M98 .040 overbore 98.00/3.858 height 23 Comp.ratio 8.5:1



Please let me know, as itīs important to know which headgaskets to pic, then... with the WRX heads!
Maybe you have an idea how I can come near to 8.0:1?!

Many thanks in advance!

We went with the 0.5mm overbore Wiseco pistons. Depending on the type of head you have (and please keep in mind European head cc's are sometimes different than US spec) you should be able to calculate out your CR and necessary head gasket.

Thanks,

Gary
