Thanks to kspec, redzman, t4tiburon.
fitted all the parts, major improvement was on the acceleration, pulls a lot harder once boost comes on from 3000-4000rpm
Without looking at the improvement on the Top End Horsepower, I'm satisfied with the power acceleration that you experience driving it on the streets, but dissapointed with the Horsepower, although i've got another dyno and fuel injectors to do in a weeks time, boosting to 16psi.
The Dyno was done on a very hot day, that could have affected the Top End Power.
Parts installed
65mm throttle body from kspec
kspec airram
ported cylinder head
fidanza flywheel
turbo manifold from t4turbotiburon
apexi exhaust control valve (reduces the exhaust noise by 10db)
once fully on it pretty much cancelled the exhaust noise
Its still detuned because with the new piping and hardware modifications.
I need to upgrade the fuel injectors, its maxed out.
CAR POWER READINGS BEFORE IT WAS TURBOCHARGED, STOCK OEM
0 psi
126hp
OLD POWER READINGS, completed in October 2005
16psi
205hp
NEW POWER READINGS, after the modifications
10psi
220hp

220whp @ 10 psi sounds decent mate.
16 psi should easily put you past 250-260whp... Maybe even upto 270-280whp with good tuning fing02.gif
Is the exhaust control valve sorta like a throttle-body mounted in-line with the exhaust piping? I think I read about those somewhere... Good idea for for keeping the noise down for daily driving but does it in any way hurt top-end performance or spool-up time?

Apexi ECV, installed after the cat.

I'm not sure if it affects the power, I didn't ask for Dyno to test.

if your not impressed then somethings wrong.. if you tuned and boosted at 16 psi you should be around 260 whp ish which would have been 55whp increase over your last setup which is perdy good for IM, TB, turbo manifold, flywheel and ported head..
what stage port job is it? just a street port, or race port?
im not familiar with your car or its mods, but could you post up a mod list of internals, other performance mods, etc. so i can see kinda what you have compared to what i have

Peformance mods
stage 2 ported cylinder head
stage 2 camshaft
garrett gt28rs turbo
sard fuel pressure regulator
haltech ecu
kspec airram
kspec 65mm TB
fidanza flywheel
3inch straight through exhaust
high flow cat
hks ssqv bov
oil catch can
48hp fuel injectors
255L fuel pump
hybrid intercooler
iriduim spark plugs
98 Octange Gas
hyundai coupe 1997, 1.8 litre engine.
I had the engine block, pistons, rods inspected and they are in very good condition with very little wear.
With the modified parts bolted on the car, I would have thought I'd be cruising past 300HP by now.

with stock compression, and the 1.8L motor, and no internal mods, i would say thats very good for 220whp @ 10psi
it would be impossible with those mods and at that psi to be cruising close to 300whp.. what size is your intercooler, and what type is it, FMIC, SMIC, finned, bar and plate??
what cam is it? lift? deg. duration?

engine compression has been changed 8:5:1.
decompression turbo gasket is 2.00mm
hybrid gt spec intercooler
450 X 300 X 80
http://www.tweakit.net/shop/product_info.p...87b2f76e7aca55c
inttake 262
exhaust 272
valve intake 0.375
valve exhaust 0.375
the only thing that hasn't been replaced is the Piston & Rods.

wow, tats perdy good for using the decomp gasket and stuff with 10psi.. cuz the lower compression, u need more psi to make more hp.. like if i ran 10psi, same setup with no gasket, and same tuning, i would have more hp.. your results seem pretty good to me.. id love 220whp @10psi with that size turbo.

You have 2.5 times more power over stock... since manufacturers don't use wheel hp but crank hp... you didn't make 126hp stock with a 1.8L. Unless the dynos where you live make some wierd calculation to turn the whp into crank hp.
Seems like they made a hell of a gain to me since you dropped the PSI down and still made 15 more whp... I would expect 275 at your next dyno @ 16psi.
