Szia! I have to say I'm impressed that you got 132 whp out of this setup, but this was with the HKS 272 8,1 cams installed? But with the big port head, and bigport intake manifold w/TVIS? Normal size throttle-body?

After seeing your drift-videos I think I might follow in your footsteps engine-wise (that is, not getting a redtop/smallport engine). A shame we dont't have drift-tracks up here were I live Actually I lived 6 years in Pécs, but have forgotten almost all my hungarian!

Unfortunately I have the low compression (9,4:1), AFM version 4AGE, but with the 7 rib block without the oil-squirters. I guess I have the lighter version / 1st gen crank + conn.rods, so I think I'll keep those parts, but will need new pistons to increase compression ratio, helped maybe by shaving the block, and a thinner headgasket.

When you switch to ITB's (+ aftermarket EMS) will you switch to a smallport head as well, or keep the big port head?

And your exhaust guy..... could he make another batch of those headers? He could probably make some serious cash making those, if they connect easily with other cat-back systems

Hello mate!

Yes my engine can do 134 whp with the following setup:
7rib block
1st gen crank, pistons, conrods
increased CR 11:1
ported&polished bigport head
HKS 272 8,1 cams +adj. cam gears
HKS valve springs
HKS oil up
lightened flywheel
TRD 4-1 header
free flow 2,5" underdiff exhaust
W/O TVIS
stock ECU
stock intake with Greddy filter

I think this is the maximum power with the stock ECU and stock throttle body and injectors, because the engine running lean. So not too healthy 160hp on crank . I'm very happy that the engine worked well on the last 3 races with lean AFR without any mechanical problems. I tried a Greddy E-manage, but it wasn't fully compatible with the bigport ECU. Sold that quickly.

I finished on the 2nd overall position in the 2nd class hungarian drifting championship with my hachi :wink:
Next year I will competite in the PRO drift league so I need to uprgade the engine.

I bought an MS-I V2.2 standalone DIY ecu like apardal and gon, and I will build my own EMS. I also bought 7MGE 315ccm high impedance injectors. And I will change to AE101 ITBs, with T3 adapter and velocity stack.
I hope this setup will good for 145-150whp 170-180 on crank.
