03 CIVIC SI WITH K20A2 HEAD & PISTONS

[Vteckidd]

We have the car finished!

I am running the car on my Civic SI injectors until I can get the RSX S Injectors bench flowed and repair two that are stuck open.

Its running on the Hondata K100 ECU with a Civic Type R Flash.
I will be heading to Knowledge Performance on Tuesday to have the K Pro Down Loaded and Tuned.

I do have a Check Eng Light on. The code says basically that the car is running too rich.

Just putting around till I get to the Dyno.

I will post more later.

If you need TYPE-S injectors PM mei have a full set with a feul rail that i pulled out of a running motor.

Good to hear, your prob throwing an O2 code which is prob causing the car to run rich at partial throttle.

Get her on the dyno an get us some numbers, im sure itll be a VERY fun car to drive

Not to go off the Subject, but whats the story on S2JZ??

As far as the running too rich, it could just be that when I ran the motor the first two days I had 2 injectors stuck open and that was just sitting in the shop, not driving it. They may have finished my 3 year old o2 sensor off.

It runs good except at 2000 to 3000 rpms where it stumbles.
I have not driven it hard and the light only comes on after I driven it a 100 miles or so and mostly if I am sitting in Traffic.

Its at Knowledge Performance now. Should pick it up Sat.

Not to kiss Main Streams rear but I saw one of your Honda S2000 on a website that had photos from NOPI.
600 + Horsepower.
We Turboed a S2K last year and had a lot of problems with it. In the end the Exhaust Manifold from Rev Hard was not large enough according to ED from Balanced Performance ad the Customer did not want to have one custom made.

We ended up with about 400 WHP but it runs better at 325.

I would be interested in a small story on that Main Stream Performance Turboed SK.

We have had much better luck with Super Chargers on that car.

Sounds good, im interested in your numbers. The car prob has tip in lean problems which is why it stutters, that or your O2 as you said is bad, just partial throttle tuning, so she should purr once shes tuned.

Well our s2k is no ordinary turbo kit . We fabricated everything on the car. The turbo manifold is a topmount, twin wastegate design. Its tubular and similar to the full race manifold. It also has a Topmount intercooler in the hood, so no big FMIC.

We used a 62-1 Ball Bearing Turbo with a stage 5 wheel rated at 680hp.

Its a built motor with Darton Sleeves, CP pistons, Inline Pro Rods, Ferrea valves, valvetrain, We ported the cylinder head very aggresively.

I suspect you had a bolt on REV hard kit which uses a LOG manifold. LoG manifolds are great for street applications, quick spool, but they suck for PEAK numbers. They just cant flow enough air. They usually max out around 400whp.

do you remember what turbo was on it? was the motor stock? if it was stock, those arent bad numbers at all.

We beat the Full Race s2K by a few whp with less boost so we were happy.

12PSI on pump gas


15 PSI on PUMP GAS


22PSI on PUMP GAS (100 octane)




We are shooting for 700whp once we get the "new" turbo in
