I cannot wait however i still have the gruelling 1k miles to endure with no boost first :/ , Its rekindled my love for the scoob put it that way, you still coming Monday Nick ?

be better just getting an open source remap, as if you get it wrong or it boost spikes kiss goodbye to the engine, Greddy or no greddy they all work on the same principle of a Diaphram which will wear, soneone i know fitted a greey to his Pulsar 6 miles it did and he kissed his Head, pistons and Turbo good bye due to it being faulty. May as well do it right mate. open source your looking around 400-650 depending on the mapper and for that witht he right mods you will get 270-280

ive got a 320 going in mine which is well over what is needed but ive future proofed, scooby worx do a really good one.

555 is martins garage :) there is a meet there on Monday :) should get yourself down and show your face and meet the gang :) http://uk.subaruownersclub.com/forums/topic/7980-sheffield-subaru-services-14th-july/

Welcome to the club matey, there is a meet at sheffield on monday but im sure Stanton will get a convoy going as your up his neck of the woods :)

Get yourself down to the subaru meet on Monday, Stanton is from up your end and im sure will get a convoy going.

WEEEEEEELLLL Progress is to be had atlast :) with the parts ordered it was time to let operation Frankenstein begin, ( Due to having heads off a P1 and closed deck block from a Type Ra etcetc) The block had been sent off for boring and honing to get rid of the nasties from the damage from the previous owner (fitting two of the wrong pistons), all the parts had been cleaned as well, part of the original heads where found inside the sump where the heads had been fitted with the wrong bolts. Friday 11th, pistons crank and casings back together all in around 4 hrs of work. as well as some other bits and bobs to the car, someone also had original Alcantara red STI interior (Full) i offered him some cash and he accepted so that has been fitted as well :) Winning. Saturday 12th 0845-1330 All the engine is now back together with the P1 heads and aggressive cams fitted, the old cambelt tensioner was a total write off again due to a bigger bolt been fitted, Martin came up trumps due to modifiying one from a new age scooby, and as such a new cambelt was timed up and fitted. Just waiting on the Td05 getting welded up and the flywheel skimmed ready for the new clutch. ive stuck with the TD05 for now otherwise ill kill the gearbox and tbh i just want to enjoy it for a bit. once the run in period is done an Alcatek Ecu with Anti Lag and Launch control will be fitted, this will also enable me to run Maf less for when i eventually go for more power. Cannot thank Martin enough for the last couple of days and i cannot wait to get the car back on the road. lots of tea and coffee where harmed during the making of the engine. here we go with the pics. DAT FACE THOUGH

Big Thank you to Martin for letting us use his premises

sorted the block ready for refitting, also cleaned the sump out where i found two large pieces of metal, hmmm mystery. parts should have been ordered by Martin as such she will be ready for the next sheffield meet.

i was there last year too, gutted i couldnt make this year. loved volvo ice stand

used them to remap my bugeye, and the Scooby is booked in there for its first map when its back together.

same sort of thing happens with the DV however ive ended up with two genuine ones off ebay so they are not all bad, whats the difference between a Vibe grounding kit and a HKS other than the money and price ??

There can be only one, in true highlander fashion. I winced when i saw this, but probably not as much as Nissan haha. https://www.youtube.com/watch?v=i-5HYQwotjk

Admiral is who im with, but keith michael, or any specialist one. Adrian Flux have always been extortionate for myself.

its in the Sales part mate.

if you get rid of the lights and they are genuine let me know.

just incase you want to sticky the information. IHI Turbos VF22 This turbo has the highest output potential of all of the IHI VF series turbos and is the best choice for those who are looking for loads of top end power. The top end power however, does not come without a cost. The VF22 spools significantly slower than the rest of the IHI models due to the larger P20 exhaust housing and is much less suited for daily driving than some of the other models. Although the largest VF series turbo, the VF22 is not quite optimal for stroked engines or those who wish to run more than 20PSI of boost. VF23 This turbo is considered a great all-around turbo. Like the VF22 it utilizes the largest P20 exhaust housing. This housing is mated with a smaller compressor housing of the of the VF24. This turbo is considered optimal in applications with range from mild to slightly wild. It does not have the same top end power of the VF22, but spools up significantly quicker. VF24 This turbo shares its compressor housing with the VF23 however, this housing is mated with a smaller (P18) exhaust side. The smaller characteristics of this turbo allow it to provide ample bottom end power and quick spool. This turbo is very popular for Imprezas with automatic transmissions and Group N rally cars. VF28 This turbo came standard on the STi Version 5. In terms of overall size, it is smaller than the VF22, VF30 and VF34, and about same size as the VF23. VF29 This Turbo is nearly identical to the VF24, with the same compressor and exhaust housings. However the compressor wheel in the VF29 is has been changed slightly. The changes made to the compressor wheel in this model are generally viewed as improvements, and as such this unit is typically chosen over the VF24. VF30 The VF30 is commonly considered the best bang for the buck turbo in the IHI VF series line. A relatively new model the VF30 features the same exhaust housing as the VF24 but a larger compressor side similar to the VF22. The combination of these two parts results in increased output potential without the lag associated with the VF22. Although it doesn't offer the top end supremacy of the VF22, the VF30 is a great compromise between these unit and the quicker spooling models. VF34 The VF34 is nearly identical to the VF30, with the same exhaust housing and compressor. However the VF34 goes back to the ball bearing design, and in doing so achieves full boost approximately 500RPM sooner than the comparable VF30. The VF34 is the most recent IHI design and as such costs slightly more than its counterpart. Top end performance and maximum output are identical to the 30. VF35 VF35 The VF35 has identical internals as the VF30 and it uses divided thrust bearings. However, the exhaust housing is a P15 which means this turbo will have fantastic spool characteristics. This turbo is standard on the new WRX Type RA. LIMITED SUPPLY. VF36 Roller bearing version of the twin scroll VF37, also has a titanium turbine and shaft for even quicker spool. Same compressor housing as VF30/34, however twin scroll P25 exhaust housing provides slightly better top end output due to reduced exhaust pulse interference. This turbo is good for 400HP and used on JDM STI Spec C from 2003 onwards. VF37 (thrust bearing) Enter the age of twin scroll IHI turbos. Same compressor housing as VF30/34, however has a new twin scroll P25 exhaust housing that provides slightly better top end output due to reduced exhaust pulse interference. Twin scroll also provides better spool up for improved low down response over the VF30/34. This turbo is good for 400HP and used on JDM STI from 2003 onwards. VF38 Twin scroll turbo with titanium turbine and shaft. Smaller compressor housing than VF36/VF37 provides tremendous spool up capabilities but less top end than VF36/37. The spool capabilities of this turbo are demonstrated on the JDM Legacy GT, which reaches peak torque at 2400RPM. VF39 Single scroll turbo used on USDM STI and latest 2.5L STIs released internationally. Smaller than VF30/VF34. VF42 Exclusive turbo to the S203/S204 models, this features a twin scroll design with a slightly larger compressor than the VF36/37 turbos and different turbine design (more blades). The VF42 is a roller-bearing turbo and is likely of similar size to the VF22 turbo, but with twin scroll exhaust housing for faster spool and superior top end performance due to reduced exhaust pulse interference.
