I've got


Air filter with cold air feed
NOLOGY Silver spark plugs
97+ RON fuel ( unless the garage is outta the juice I gota use 95 )
3.5in custom back box
custom turbo back straight through setup
Magnicor Performance HT leads
10w 50 Castrol GTX Hi-Mileage
Nipparts oil filter

so I'm only really missing the intercooler, fuel pump, boost controller and decent boost gauge. All relatively cheap to get hold of just theres no dyno's in this secluded part of scotland. It's tempting just I don't know what more horse-power will do to the already knackered engine ( compression and oil in 3rd cylinder ) might end up going something like this. VROOOOM!....BANG! BANG! BANG! JUDDER, SCREECH, HISS! KAPUT!!!! then complete silence as the engine dies...... no idea really just a thought :trout

My engine recently said "INAF!". A head gasket was blown and when i realised what happend the water was boiling in the engine. Turns out that one piston "nr. 4" got so big from the heat and srached the cylinder surface very very vaery vaery badly. the only option is oversized pistons.
My question is haw much i can expect from this engine to withstand with forged CP pistons and OEM DET rods????

s13eater 26-05-2008 15:58

probley more than you will see from the engine due to the flow of the head.so about 32psi is what i ran it on for a few 1 mile bursts, and from 23 to 26psi on std setting all on the t34, that was with det rods and je pistons.

ChEsTeR 26-05-2008 19:23

The head is of so maybe some porting.
I had a cam made 306 dergres.
With this it should reach 300 bhp?

30psi 26-05-2008 19:25

306 deg's?

Are you serious? I hope you've done your reading up about how that effects your compression ratios vs actual tested compression vs dynamic compression ratio, along with the side effects of wide overlap on a turbo engine.

ChEsTeR 27-05-2008 00:37

Th engine idled like shit but i didnt maneged to dyno it due to a gasket failure. I was tuning it at 1.5 bar from t28 when the gasket blew.

hi, I have a question that I have a problem.

I have people tell me that the injectors S13 does not fit on the CA18ET, and you said that the S13 injectors that amount.

can you give me more explanation?

thank you ;)

you have to do a bit of modification. Basically you need to fit a piece of hose to the s13 injectors to be able to attach them to the rail
