scott

You might be able to get 150or60 flywheel HP for about $4500.

oh ok thanks sidedraught. what have other people acheived? Kegs in particular u have a turboed A15 right? id love to go turbo with it. any info would b great

Doesn't actually answer your question, but at least it makes me feel better....

100-150hp (at the wheels) out of a turbo'ed A15 is not unusual.

Talked to a fellow at the Datsun club meeting tonight. He's bumping boost up and hoping for 150hp@10psi wheels soon. He apparently managed 120hp@6psi.

Food for thought.

hi scotty01
i think the cost is really up to you.if you want a cheap and quick way to turbo it buy a cheap late model turbo t25 or t28 eg and blow through a 32/36 weber and use a malpassi reg and boost retard on the dissy timing. thats basically what im looking at trying except im probably going to put new duralites with lower comp ratio and a decent portjob/cam etc and maybe try holley 350 carb.this setup worked well on 2 litre escort and was quick and reliable and drove fine for months.

My A-15 was put in by the previous owner & cost him $1700. + extractors ($400?), + about $140 for a 32/36 adaptor & full rebuild kit.

polished head
lightened flywheel
Extractors
32/36 DGAV Weber carby
mystery cam- I was told by the engine builder that it was either a 30/70 or a 35/75 but the guy had lost the cam card so I don't know.

It is a good fun combo, remarkably torquey from 2000-5000, but at the end of the day I dont reckon it would be making more than about 100 hp at the flywheel.

I am thinking of running a bit of boost through it, 'Wally's wagon' style.

ok guys well i have another question for you all... here are the conversions i am interested in doing.., Turboed A15, n/a SR20, or a CA18DET?!?! the SR would b aproxximately 105kw stock, am i right? but form the figures given in this thread i would b getting that from an A15 after all the work converting it to turbo? i hav been advised that an SR would b very hard to install, but what exactly would b involved? also the CA..what is involved in doing that and what would it b like to get eitha of these engines engineerd/registerd in south aus?thanks

hey guys i gotta a few questions but i dont no much so could u answer them in basic terminology i think scotty01 asked one of them im also in south oz and was wondering how hard it would be to get an engine registared and installed etc.... also does it cost much? also wats 32/36 etc etc ..... lil dumb with this but thanks guys

In answering your first question, if are doing the work yourself on say a CA18 turbo it will cost $10,000, if you are paying someone else double it.

A 32/36 is a down draught Weber carb, common cheap upgrade.
