How much @ 5 psi? If i get a boost controller how much is the max that i can boost....?

 

I would think that kind of information would be available from the Greddy website, in their literature or from them directly through email or a phone call...

 

It's usually around 160 or so horsepower at the flywheel. This can be plus or minus ten horsepower, depending on the condition of the motor, weather, etc. When I was tuned at 7 psi, I ran a rich fuel map and got 179hp and 175lb-ft of torque (flywheel). The HKS VBC was also ******* up, so it didn't hold boost correctly. All that torque was fun, though. Sucks the overall numbers were kind of low. And how much boost can you run? Depends on your wallet!

 

ill just think this as a way to get the power similiar to a gsr.

 

Pretty much. That's why people always say, "Why boost a SOHC? You're better off swapping" and all that ****. Good points on both sides of the debate, but for me it was just a personal preference. Either way is damn fun, though.

 

but a stock gsr doesnt go Vrrrrooooooommm!!!!! PSSSSH! vrooooommmmmmmm !!! PSH!!!

does it.

i rest my case.

 

im just wondering how far can i boost on a stock sohc w/ the greddy kit. Im going with 8...but would 10 be pushing it?

 

Tuned 10 psi on a greddy kit should net you over 200 and it would be reliable. Don't go over 220 though. I'd say that's the limit for the sohc rods. (yes I know people have made well over but for reliable daily I'd say 220 is the stopping point)

What he said is right on...

Tuning is your best friend when boosted...

 

id agree with stayin in the 220-230whp range on your stock guts.
as for the GReddy kit, without a boost controller I can get my adjustable wastegate actuator to hold 11psi steady, and on a motor with cracked ringlands I made 188whp/159wtq

Compression test showed 195-185-175-100 on a JDM D15B VTEC

I know I woulda made 200whp if the motor woulda been good.

 

i have a 92 cx with a vtec zc motor in it and a greddy kit. the motor is 100% stock other than a new water pump and timing belt. i'm pushing 9 psi on the stock wastgate and it kreeps to 10 psi before redline. i'm running uberdata and i know that i make over 200 hp. i can put a *** wooping on my friends hatch that is just like mine but has a jdm type-r motor swap. i also have another friend with a 94 si with a jdm type-r motor swap with more than the normal mods and i get him pretty good as well. as far as the gsr thing, another buddy of mine has a hatch like mine with a us gsr swap and my car with 4 people in it makes his look like it's in reverse. sohc with boost

wow

 

Wow, can you have whoever tuned your car do mine!???

 

you can make plenty of power with the greddy kit, on sohc I bet you could probably make over 250whp, if not close to 300whp.

BUT(yes there is a but) your engine cannot handle anywhere near that much in stock form.
it'll only take maybe around 190whp consistently and reliably, and thats only if its tuned to perfection IMO.

170-180whp seems like a great ammount with at least some peace of mind( again with a proper tune).

 

u should visit http://www.turbod16.com it has TONS of info

 

l miss my sohc turbo greddy kit was amazingly reliable

Doubt that. Greddy kit won't make much over 220. It's a small turbo. If I was you, trooper, I'd piece together a kit. Grab a nicely sized t3 with a drag manifold. ANd piece the rest together. Not sure how well 450cc dsms work with uberdata but you can pick a set up for cheap. I still wish I would have done my own kit and had it tuned. I might redo the setup when I get money. Right now it's just stock del sol for me haha.

well i know ppl that made over 200whp at 10psi
the turbo has plenty more to go than that.
i mean, not a HUGE amount more, but its hardly toast.

its a small turbo but its not like its a puegot turbo or something

 

apexi ball bearing is the **** apexi sohc ball bearing kit on my ls cmon chi just swap to ls haha jk

 

^^ u got sprint? sanyo 8200?

haha, anyway, you should be looking at stopping at around 180whp...

i myself am looking for a greddy kit.

 

What would need to be done to the bottom end to up boost?

&lt;-----Boost n00b

 

you can run 12psi no prob on the sohc

 

You can up the boost as much as you want, but you'll have to stop when the hp gets around 220, as posted above. That's the rule of thumb for the D-series rods----quit around 220 to be safe and make sure the rods don't bend. Stay with this rule even more so if it'll be your one and only car.

And the A'PEXi kit is badass. I should've nabbed one when Gruppe-S had that ******* huge sale after A'PEXi decided to quit producing them. Those things went with the quickness. Edelbrock kit doesn't look at all bad, though. I don't know anyone who has one except Marauder, and even then I don't really "know" him except from this board. But it looks sweet.

 

220 whp or flywheel hp?
