Info/Purchase

Slowboy Racing GT-10
(44 lb/min, 275-325whp, Bolt-On)
On many 2.0l WRX motors, people running the basic bolt on modifications can expect 275-300 AWHP on a good tune with pump gas at 18-20 PSI. Those wanting to run race gas and 24-26 PSI can expect upwards of 325-330 AWHP.
Many 2.5l STI owners have been impressed with this turbo from the standpoint that it spools up very fast, but its limited flow capacity has limited this turbo on pump gas to around 320-330 AWHP at 18-20 PSI. Many 2.5l STI owners would be better suited with the GT11 or larger for those looking to make more HP.

Slowboy Racing GT-11
(50 lb/min, 300-350whp, Bolt-On)
2.0l WRX guys who intend to run a lot of boost pressure, tend to like the 700177-0011 CHRA from Garrett, however it is certainly not a pump gas king. 2.0l WRX owners should expect between 300-325 AWHP and STI owners between 340-360 AWHP at 18-20 PSI.
Switching to race gas and running between 24-26 PSI should yield another 20-30 AWHP on this unit.

Slowboy Racing GT-12
(55 lb/min, 350-400whp, Bolt-On)
2.0l guys can expect a bit of lag from this 55 lb/min CHRA, however it is capable of making between 340-360 AWHP on pump gas and 18-20 PSI on a well tuned motor. The majority of the 2.0l fanatics tell us you must get this on a dynometer right away to get the most out of it. They also say at 4,000 RPM’s its time to hold on tight, because this turbo hits HARD!
This turbo is where the 2.5l guys need to be from the start, the extra displacement provides enough grunt to get this guy fully spooled before 4,000 RPM’s and is simply a great turbo for a daily driver who wants to make 360-380 AWHP on pump gas at 18-20 PSI. Expect over 400 AWHP on a great tune up, all the supporting modifications, race gas, and boost pressure between 24-26 PSI.

Slowboy Racing GT-13
(60 lb/min, 375-450whp, Bolt-On)
For the EJ20 guys, this is a big turbo capable of flowing 60 lbs/min of air. This turbo on a 2.0l motor will not achieve full boost until the low 4,200-4,300 RPM range. This means, you better be revving your motor to 8,000 RPM’s to make the most of this turbo! Since most of you are not revving this high, we suggest for the most part this remain an EJ25 turbo for the 2.5l crowd.
The STI fanatics have reported some success with this turbo using only the true bolt on compressor cover; however we suggest using the 3” inlet cover to get the most performance out of this particular CHRA. 2.5l guys should expect between 350-400 AWHP on pump gas at 18-20 PSI, and upwards of 430-450 AWHP with race gas and 24-26 PSI. This turbo is very capable of 30 plus PSI; do not try this at home! Dynographs coming soon.

Slowboy Racing GT-14
(65 lb/min, 400-500whp, Bolt-On)
Unless you are a fully built, hi revving EJ20 please look the other way! This turbo is hefty, you will not go looking for the beef any longer with this turbocharger!
This turbo is much better suited on an EJ25 with higher than stock compression or someone that has a bit of tolerance for a high boost threshold and is willing to have all his fun from 4,500 RPM’s and up! This turbo will only fit in the 3” compressor cover, so direct easy fitment is not certain, however smiles are guaranteed once you have the fitment behind you! Expect 400-425 AWHP on pump gas between 18-20 PSI, and capable of 440-460 AWHP on race gas. Dynographs coming soon.

Slowboy Racing 35R
(65 lb/min, 450-600whp, May Require Modification)
EJ20, 2.0l cars have not even tested this turbo yet! So, at this point we are unaware of how it would perform.
On a mildly worked EJ25, this turbo shows remarkable spool up for its size, which we contribute to the larger turbine wheel (same compressor wheel as GT-14, however the turbine wheel is larger). On all inline motors, the GT-14 spools a good bit faster than the 35R, however not on the EJ’s! This turbo has made over 405 AWHP on a 2.5l at only 19 PSI. It makes almost 400 ft/lbs of torque at 4200 RPM’s.
If you have some patience, and are good at making things fit, this is the turbo for you. Pair with our 3” inlet for a somewhat easier fit. The install is not for beginners; however it will bolt up to your stock up pipe location! Make sure you call and talk to one of us before ordering online.
