CA18ET Max hp?
 

I posted this up on club s12....but not many responses, so I thought I'd post here.

How much power can the ca18et make? Whats it capabile of?
Whats the max it would make with the stock cam, and head?
Whats the max it would make with aftermarket cam, and ported head?

I'm asking because I'm debating on getting that HP Performance short block rebuilt kit from Flat Lander, and a set of their Pauter billet rods to go with it.
They told me the kit is good for 800-1000 hp, and the rods are good for 40psi.
They said the block and crank are good for around 700 hp

Scroll down to # 9 for the parts list of the kit....

I'm trying to figure out if this build up is worth the $$, or if I should scrap the whole thing and go CA-DET. Only problem is.....I won't have the $$ to buy a DET and rebuild it too......so it would be going in bone stock.

Any help would be great

a mate of mine has got 305.6 bhp so far out of the 8 valve and there maybe some more to get from somewhere, Have a look at his profile S13EATER

If you are paying $$$ for ultimate power than the DET wins hands down. Absolutely no contest.

True much more power available from the twin cam

Yes, yes I agree......and is not my question.......like I said in my first post......if I get a ca-det then I won't have any extra $$ to build it up....it would go in bone stock + my existing bolt-on mods I currently have for my ca-et.....fmic, t25g, s-afc2, walbro, etc, etc
Or spend the same $$ on my ca-et for a performance build-up......but if I can only get 200hp out of it, then it's worthless to go that route.

mmmmmm, pretty impressive. Do you have any info on it.......there is nothing in his profile:(

you can get a DET that needs building for £50

Where? If I did my conversion right, thats like $95 USD?? I would still need the complete motor set with all the wiring goodies. All of the ca-dets I've found average around $1200 USD + shipping

what your really wanting to know is how much power the stock et head can give.

350BHP is probably the upmost maximum for the et with abosultley everything played with but Nitrous

The det can do this on the standard head and a healthy well maintained bottom end

I've got about 12 of them that I've picked up from garage clearances/rebuild exchanges (used to run a 200sx garage) etc, I guess it's harder in the states as they were never sold there. $1200 for a non-runner is terrible!!!!!!

that's a fair assessment, the ET head is a definite bottleneck, the inlet and exhaust ports are the worst I've ever seen

I know 30PSI has fitted the ET head to the DET block. If the ET head is so restrictive, can a DET head be fitted to the ET block? :confused: Or is this impossible? :(

i have seen a standered s12 with induction kit,zorst nitrous do a 1/4mile in mid 11sec :D at santa pod so if you have a healthy engine get a progressive nitrous kit and chill im thinking of this as ive only got 37k miles on my s12
just uprate the usual stuff and nitrous it mid 11sec maybe more laughing all the way with the gas if you are in some what of a budget or det the car with a few mods and you will have a good platform for future high power outputs

I spoke to a guy who i sourced an engine for and he was doing 13.1sec 1/4 miles at the pod on a standard engine on 14psi.He was using a nitrous kit.

I do wonder how much the std and a modified et head could do for sure.S13EATER could probably shed some light on it when he comes back from holiday.:D

thats the bloke pukka that i met and seen his car a few times at the pod his a bit of a regular at the pod like myself when i had a the orange s12

i'd say about 330bhp, i still need my cam timing in and there's another couple of things i'am going to try, its still going strong, but the fj is well under way so maybe someone would get there self a bargin and buy the engine with the forgies, headwork, t34, top mount exhaust manifold, plenum and god knows what else its had done.

FAO S13 Eater,

hiya mate,

did you ever get the CFM flow figures for your 'before and after' ET head? I remember your current head is somewhat trick aint it? or does anyone know what a stock head and a flowed head figures are?
CNH
ET fan....:D

hi craig, the so called ported SE head flowed 85cfm, mine flowed around 94 cfm, but that was with only a 81mm bore adaptor, it would have flowed more, but andy @ amt din't know it was a 83mm bore until i showed him the s12 manual.

84 with forgies ;)

cheers Shaun and Sideways.

i have a spare head kicking around and was thinking of getting it done for next year. Im collecting bits at the moment for a tublar top mount and elbow.
Whats the pros and cons of tubular elbows (of the turbo rather than arm variety:D )? i have one that has a seperate wastegate dump pipe that reconnects to the elbow and thus exhaust gases about 6" later. In power terms, would i be better off making it connect further down into the downpipe? or maybe make into a screamer pipe? Only interested in performance gains, not a cool sound. How loud are screamers? wonder if they will pass circuit sound tests?:confused:

my screamer is fairly load, so you maybe best using one that joins back in, although if you used a large external wastegate with a large screamer pipe, then it would probley be less noisy.

the SE one was 75 cfm not 85 cfm, i went to AMT and had him look up the graph.:)
