2005 Type-S
Searched and came up with 290-310hp is the limit for the k20?? RELIABLY!!

Looking to boost it and was wondering how many ppl are at or around 300 whp or higher on a stock k20...

What boost pressures? What kit? For how long? Driving style?

Thanks in advance

 

You should be fine with a stock block at 290-300hp. If you beat on it, you may have trouble with the tranny.

 

take a look at a boosted k20 with stock internals ...

stock block can handle atleast 280 HP....Its a Gee motor if you tune it correctly. I personally have not even tired to get that point but I know many that have. GO FOR IT!!! k20z1 FTW

 

lmao @ 41 psi on a stock k20....thats awsome....haha

 

I have a 02' Type S with 458whp. The K20 motor can handle about 318-326hp with no problem. But if you want more hp change out the rods and pistons. Then the intake manifold, heads, injectors and what not.

 

lol i send out stock motor rsxs' with an easy 450 all the time... lol old thread

 

i hope your just guessing and not actually serious with this post....stock internals can easily handle upwards of 500 whp
yeah this...at least you see the same stuff i do on a daily basis hahaha

 

thats wicked. . . dam 41psi.

 

on stock internals....wowowow...go honda. shows all competitors we dont need all crazy upgraded parts to have mad hp

 

Im aiming for 370-400whp on a stock z1 bottom end on 15psi an 91 octane.
just really need to have a clutch to keep up with the power.
oh an that turbo helps too.

I know a k20a2 can handle a happy 15psi for a long time
essentially every pound of boost is just under 10hp
just get a good tune an 300+hp should be easy... but $$$$$$$$$$$$

 

what turbo are you going with? 15psi will net over 400whp on most turbo's

 

well im getting head work done too so that plus 15psi will hopefully be over 400hp when im done.
For starters im goin with an ebay kit. couple people on ephatch have had no trouble for over a year with the same kit & its only $679.

After im definitely goin with a precision 60 / 63 maybe.

here's the link to the ebay turbo

i worked on a car with that kit, its total ****, i don't wanna be a dick but yeah man.. these turbos commonly come apart on their own.

 

hahaha yeah it's a fraction of what a regular turbo kit costs so it's really just good for parts. a few things were changed to insure the durability like the wastegate, oil feeds, a lot of clamps, & dump tube.
But if i hear good things about a shitty product, hell sign me up. whats the worst that can happen?
just like that obx LSD. crap company (that seems to be coming up well)
