ER34 turbo upgrade

[colin]

Have a R34 GTST and looking to purchase the Apexei AX53B70 kit from Greenline.

Just figure this turbo and new cams seem a good upgrade for my unit.

Have pipe and fount mount IC with power fc and boost controller.

Ive not tuned yet and waiting for final upgrade.

Im looking for 250kw daily driver.

Done all serch on turbo but have not seen comments on this IHI Apexei unit,

Greatfull for sites advise. Arial

can't say i've had any experience nor do i know anyone with an apexi kit. i must say, good to see someone venturing down the "non hks bolt on turbo" route, what makes you stray away from the conventional hks 2530, 2535, 2540 or 2835 bolt on options?

Yeah we sell the same kits atr work and i'm lookin at doing the same thing......

HKS is done to death and the AX53B70 will get u that power but will be a lil more laggy but with a AX53B60 will come on boost quicker and just make less power.....

But they are a straight bolt on and Come with full kit braided line head gasket etc....

Can i ask how much your paying?

Might be able to get you a better deal

[franks]

being done to death doesn't necessarily means its a bad thing though? it just means its a great bolt on mod?

how do the apexi AX53B70 and 60 rate against the hks turbo's? ie. is the AX53B60 equivalent in size to say the 2530?

ax53b60 is 340 PS

ax53b70 is 380 PS

hks2530 is 320 PS plus HKS 10% gives you 353 PS

the apexi turbo's are rumored to have fast spool up.

i would be looking at an ax53b70 kit if I was going to change my turbo, something different

see attached ms excel spreadsheet, covers rated PS and specs for some of the common turbos. i've added the following rows

Horsepower (This is the PS converted to horsepower)

Kilowatts (Estimate - based on stock power loss for rb25det?)

Power at Wheels (Estimate based on stock power loss for rb25det)

The rows i've added are merely to see what they were. they are by no means accurate

the other rows were found from a webpage

Mario (Infected Flow on SAU) will be putting on an AX53b70 soon with Tomei 260 cams on his ER34.

I'll let you know how he goes

ill be anxious to see the results. with a powerfc, afm, cooler, exhaust, ax537b0 @ 1.3bar i'd expect around 250rwkw with a fast spool up
