Default Another LHT4000 turbo, 98 Civic EX

Correction, the LHT4000 kit is still having map sensor problems......LOL
LHT400 kit is availble !

This is based on the LHT400 turbo which is a complete built, installed and tuned designed for upto 430whp with a fast spool and keeps the AC and PS 100%.

This car car we swapped the sohc for a built GSR about 1 1/2 years ago with a turbo in mind. Well, the car is back at LHT and the Turbo kit is complete.The LHT400 kit comes with the complete turbo kit, 3" down pipe and exhaust, Hondata , 880 cc injector, boost controller etc etc.





Note the Dump is re circ into the downpipe, no anoying waste gate sound!



All intrcooler piping in aluminum, 4 ply connectors and bead rolled, this was polished for a nicer finish.


We use precision intercooler, we have found them to be the best and fit with the factory bumper support. Notice the minimal cutting of the bumper.


Upgraded SPAL fans, this is another thing we use and recomend, these move a little over twice the CFM of the factory fan and measure only 2.4" and the thickest part.


Also notice the full intake, no mesh over the turbo with the LHT400 kit.



Even the water bottle is retained.


Here's the 3" stainless exhaust with resonator tacked ready for tig welding.

Of course our downpipes run a stainless flex connector for long life and reliability.


This is of course our stealth system, 3" all the way with a small slash cut tip




Dyno will be up soon, This is a real street car so the HP will be in the mid 300 range. No dyno queen that doesn't run here.....

The dyno went fine , 348whp at 11 psi with complete stock ignition and 7es plugs = super driavabilty and idle .
The car feels very smooth and fun to drive, enough power to boil but easy enough to handle.
