Kelvin's 566whp LR2.4 GTW3476 92 Octane
Kelvin had purchased one of our other customer's ER built LR2.4 Evo 8 and at first enjoyed the HTA3794 and big power. After awhile he decided he wanted a faster spooling combination than what he had. Since he had a very good foundation laid for a big power 92 octane car, we started looking at turbochargers. Initially he was going to try the GTX3576 but things stopped him from going on the car for a bit. After awhile he chose to purchase the GTW3476 instead since it was very similar to the 3576 on paper.
I am normally fairly close on my estimate of what a given combo should do but I was very surprised at the first pull in this car. Where I was thinking 380-390 at 20psi, it did 550 at 24psi because of the WG spring combo. Kelvin was using the following parts from us to achieve this goal --
EnglishRacing LR2.4
English Racing Bushmaster full race port cylinder head
156mm R&R steel rods
Wiseco 9:1 pistons
GSC Motorsports R2 camshafts
GSC +1mm valves
Fuel Injector Clinic 1100cc Hi Z injectors
Kiggly Beehive valvesprings
Kiggly HLA
Magnus Motorsports V5 intake manifold
ETS T3 turbo kit
ETS 4" intercooler and piping
3" TBE
Eagle 100mm crankshaft
The car was originally assembled as an VIII clone of my IX, so alot of attention was spent on the cylinder head by Jeff as he was assembling the engine. The same procedures and pattern that he uses for the cylinder head in his 7 second Eclipse was applied to give the best breathing cylinder head we could have.
Here are the results -
All pulls were on 92 octane with no additives. The second pull didnt pick up much power as it was already on the edge of being happy and the timing was lower with the 2psi increase in boost. All in all it was very surprising to see the results from a "little" turbo on pumpgas.

Aaron,
Thanks again to you and your team this great experience once again. By no means is it a close drive to ER but I've made multiple trips there and not a single regret.
Originally I had the T3 2.5" outlet. But the stupidity in me forgot I had a 3" downpipe already. So we had to get a machinist to bore out the housing to 3" and we had to custom vband the housing to fit. You can get it from any Garrett distributor, I believe you can order this through English Racing themselves.
I didn't need to mod my downpipe, I had to mod my housing. Well I guess eventually I had to mod my downpipe to work with the vband. Read above reply for why.
