Greddy Upgrade (theoretically speaking)

any spiking or creeping with the Berk HFC? I am installing mine next week
!I can't wait to see if anyone will offer this option of stuffing 20G internals in our 18G housing. I may want it down the road.
Wow! That's pretty awesome. I only wish there were more Hybrid turbos, that although they are compact, can pack a punch.
Congrats to you guys for what you have done and are doing. Keep up the good work.

funny you should ask about the t67. i made an adapter that bolts the T67 to the GReddy manifold. I was able to bolt the turbo on but the frame rail is so close it made it next too impossible to install in the car. i need to modify the adapter to get it to fit a little better. I think i figured out a way to make it without modifying the manifold for an external wastegate. for now though, the 20G will get it's last dyno run at 26 psi tomorrow. personally for the stroker I think the 20G should be fine for good low end power. tyler, the driver, likes more bottom to mid then top end but we are going to test a set up before buttonwillow with the T67. Since that isn't a protype turbo for the GReddy kit, I'll let you all know the results on that one.

My 2.47L F20c is built and when I have time I will bolt it up to my T67 setup. The T67 was great with the 1996cc, it should be a heaps of fun with the 25% extra displacement. You will probably beat me to it but if I get a chance to complete it before you I will let you know as well

Do you have any dyno graph of the 2.47L with the T518z turbo? It must be very torque
Edit: just read about the 382hp 350tq. Nice
trbokev, no prob i figure it was about time i went on here. i'm usually antiforum but I've learn to change my ways. hahaha.
chris. before my other post with power numbers, i tested a particular set of BC cams that i like. keep in mind, we test a lot of the prototype cams from Brian yet only the one's that work come out... makes sense. any way, don't quote me on the part number but i wanna say it's the 0061 seem to always work for me. this was the best part. we ran the car with the 20G back on stock cams cause we seam to always put stock cams back in after a turbo change. so at low boost we were at 360 hp and i told tyler we were gonna put the 0061s in and it should be good for 18-20 hp. funny thing is that was based off of the 2.0 and 2.2 we tested on these cams. with the 2.4 it made 22. pretty predictable cams, they always work for me but do lose a little max tq. let me get you the correct part number first but i'm pretty sure it's the 0061 cams.
honda9krpm, honestly I'm pretty anti big turbo for road racing but i'm slowly starting to think it might be the right choice. if you go to a track that never requires being below 4000 rpm then a big turbo might work pretty good.

here's the update on the 20G without ruining the magazine story. it broke 400 hp at 19 psi with the lower 9.5 compression. but the best part is none of the tq fell off! i never dropped below 300 tq up to max rpm. this is by far the best road race turbo i've seen for an s2000, the only thing i'm sad about is that we didn't make more top end but I'll take the flat tq curve anyday. i'm a crappy road race driver but the last thing i want is to get off the throttle and not have the power back up when i floor it. i guess we'll see how things go with the new set up. btw, there is a slight chance the car is gonna make it out to VIR to attempt to win the Redline time attack championship. if you wanna see the set up and see what had to be done stop by next weekend.

That's my next goal it so increase to a 3mm and up the boost, Gary did you use the 3mm or 2mm or was it the in-line pro HG? Great numbers I hope to do as well. It goes to show you can bolt on multiple turbo to this kit and increase the psi with this mani, that was my one fear.
Guys on another note if I go 2-3mm will I need the following:
2-3 mm hg which one?
new injectors 750's?
ARP studs or OEM?
Any additional stuff need to increase 16+psi for the greddy ult?
Tune
Would you consider doing anything else?
how much do you think it will cost in parts and labor?
Please feel free to add any additional comments.
mods are list in my sig if it works.
