98 Camaro "Kerminator" 25.5 Build Thread - PICS We are going a different direction with our 25.5 cage compared to most styles that we complete. We are keeping the entire cage within the car to allow for our maximum exhaust clearance (We are running 3.5" y-pipe fabbed into 4" straight back to a pte thumper 91mm).
I'll use this thread to keep the build updated, please feel free to ask any questions.

Wow cool deal, I am doing the same thing in a big tire version, building my cage floor up a little higher so I have room for exhaust under for my 25.5 BBC tubbed car.
Any pics of this rear mount setup? Guessing it is mild steel? I am debating mild steel or CM myself at the moment.

looks good...similar approach to how we did mine. Are you planning on keeping bars 2A and 2B inside the car? Looks like you are keeping bar 6 in (foot bar) based on the picture...

Phil: It's actually the GZ Motorsports kit. We had to fabricate a new bracket for the pump due to the spacing of the motor/solid mounts, etc.

Bit off topic on the thread, but definitely RAGEN I'd say that is a good deal. The moly and jig notching alone is a lot more than that, and is this fully welded or just the kit unwelded?

Matt any reason you're putting the turbo in the back, other then there's alot of room back there for one with the stock fuel tank gone?
I have seen some cars recently that have gone that way, apparently it doesn't really matter where you put it. I always thought the turbo needed the heat from the exhaust to help keep the exhaust gas velocity up, but apparently that thinking is wrong?

yeah, the turbo could pretty much be plumbed directly into the intercooler I'm sure if you get imaginitive with it, no downpipe to worry about routing, and the charge pipe can run thru the car so that's not a big deal either.
It was always my understanding that the exhaust velocity and heat was what spooled a turbo, putting it in the back would seem like there would be a bigger lag period before it would spool up fully because the heat and presure would have to build up all that way before it got to the turbo, plus the amount of heat that the turbo wouldn't see because the exhaust has cooled in the time/distance it takes to get to the back of the car would also effect what the exhaust could push/spin.
Paul major has disproved alot of that with his rear mounted turbo vette, so there must be a way around all that.

This one seems to run ok, even though the turbo is in the trunk

Cars looks good..... Love the Color
Green race cars, oh boy!
The entire thought process of this was to build a very stout drag radial turbo car, that theoretically I could put into a customer's street car. Thus the reason for right now we are wet sump, double roller tc (no jesel), stock ls7 rockers, rearmount turbo, etc. I'm not saying we'll throw a 91 thumper in your street car, but with our one-off custom bent turbo kits in house we can use a nice front mount a-a intercooler, kooks headers, custom turbo back exhaust with an aluminum block up front.
The plans after we make this combination proven will be to go further with the Jesel belt drive/valvetrain, Dry Sump, etc. this will be going on with the 114-106.
GForce: And it will run very well too. Look at Paul Major's trick setup, he's running a few of those huffers in the trunk and that car moves out.
RAGEN: Yes that too. It puts more weight on tires, and we're going to be skating on drag radials this year so anything helps lol.
We will be running Cecil County 1/8 mile DR sat. night shootouts, atco/etown 8.50 index, lsx shootout memphis, street nationals, drag radial outlaw championships... I'll have the schedule posted on our website within a few weeks... Hoping to put down some stout 7 second passes.

After we complete the 25.5 then the turbo project starts. We still have to refabricate the motor mounts to drop the motor/trans down a bit. There is still a decent amount to go on the project but we're forging forward. June 6-8 @ ATCO is our push, but my team would never rush anything for safety sense if it happens it happens... If not we'll definitely be down there with another car.
