Default Juliusí 98 GC8 Hack / Sleeper (aiming for 9s)

Hey guys,

Long time listener, first time caller - all the way from New Zealand.
*
I have a s****y GC8 SRX (non turbo JDM model) that I picked up for $1550, because it ainít flash.
*
The plan is simple. Take one semi light GC8. Add a GRB EJ257 engine, GRB EJ207 JDM 6 speed driveline, a big turbo and all the fruit to have some fun.
*
My aim is to crack a 9.99 second quarter mile, this I have dubbed it #9sOrNothing.

Made a little video checking it out:
* https://youtu.be/akLU2IZv00g

So this is what it currently looks like:
*

*
Iíve started dummying up the intake which is a GRB item that Iíve ported, shaved and added a larger 3 inch throttle body.
*
The alternator flip bracket is a Keinfab item and pretty awesome quality

Started dummying up the turbo. Iím going for a Borg Warner EFR9274. Itís pretty damn tight running a turbo in this configuration on a GC8.

Iíll drop a few pics of my collected parts and work so far.

Drive by wire throttle pedal. Iíll probably be using a Link ECU to control the setup.


Big intercooler and mounting of it.


Plated engine hardware for the build.


OS Giken triple plate clutch and pull to push conversion kit.


OE 12mm Pump


IAG 1/2 inch studs and head gasket

This is going to be good!!!

That’s a pretty clean gc8 for $1500, good find.

9’s or nothing, I like it.

Itís definitely a bit tougher than I wanted, but I canít complain given the price.

Front tyres were shot (thus the legacy wheels that went straight on the front)

Right front guard with a weird cut

Damage to the boot
Scrapes on the front bumper

So Iíve already found a straight boot (without spoiler) and RF guard. Iím not going to worry about panel or paint until this thing is reasonably well developed.

Anyway, hereís the IAG studs I mentioned in the previous post.

My EJ257 block has been close decked.

Iím going to be using these Argo rods. Theyíre an Australian made product that Iíve seen used very successfully in countless Rally engines, as well as 1000hp hill climb engines.

Iíve started hand porting these heads myself. Pretty happy with the direction theyíre headed, just a few more hours to get them done.

Ok so a little rough, but not too bad. Wow your already moving pretty fast on this. Keep the updates flowing!

I’m gonna look into those Argo rods, they sound legit.

We never got turbo GC8 models here in the states. Swapping in newer model turbo engines was the only way to go. Cool build!

Are you using the 5 speed or will you switch to 6 speed?
