My new shortblock


I wanted something that I could rely on even at high hp levels, so I built me a new shortblock.

good luck with that puck clutch on the street heh. The block looks gorgeous, I hope to do something like that with the one I pull out of my truck soon.
 
That is a sexy beast. So what are the specs? What did you do different and why? My plans still call for a stock type build using stock turbo pistons. Using a Garret T-3 and plan on 15psi.

Sad story: I can't use that clutch. I got the 4-puck for an 88 t-bird. It's listed as 9.25 diameter, the 83-86 disc is 9 1/16. I have a Centerforce stage II pressure plate which is listed as 9". I put that disc in and it wouldn't disengage, so I had to pull the tranny and put the CF disc back in.

It's .020 over with diamond pistons and total seal conventional rings. I overbored as little as possible to keep the walls thick, and used an early turbo block since they have thicker walls.

I got crower rods which are rated at 500hp and 8200 rpm. I'll likely only have 400rwhp and 7000rpm, but I wanted a good safety margin.

ARP head studs and felpro 1035 are to keep the boost in, cause there will be a lot of it, about 30 psi.

This is the stuff I did to it in the past, but it runs on e85 and has a MAF conversion on an LA3 with 96 lb/hr injectors. It's got a big FMIC and a tubular header that I fabbed up, with a HKS blow off and e-bay TiAL wannabe WG. In the head there are oversized SS valves with hardened seats, dual springs and titanium retainers. The cam is a mild ranger re-grind I got from delta cam. Some mild porting has been done. Exhaust is 3" with a hi-flow cat and a Summit Racing glasspack.
 
What cylinder ended up cracking? I have heard that the rear cylinders on E7 and E8 turbo blocks are cast very thin (like .120") and are prone to failure if bored out. Makes me wonder if I should get the rear cylinder ultrasonic tested to determine wall thickness when I rebuild my mill.

Oh, and sweet build! Much wilder than the build I am planning for mine!
 
That was the #4 cylinder, on an E8 block, and was not overbored. There was no damage to the stock turbo pistons or the 8993 head gasket.

Good for you! That is one SWEET looking little engine!
 
Thanks guys. I'm lovin this shortblock!

I turned it up and at about 22 psi it's screaming. I really need to get a new 4-puck tho, cause the old CF disc cant hold the torque.

This just seems like a funny statement while talking about a 2.3. I have one, and too much torque for the clutch has never crossed my mind lol
 
turbos really wake them up... the fuel bill goes up though...
