Chimmike do you know the housing sizes on the aps single turbo?

 

Didn't chimmike already mention this multiple times in this thread? I think we've all been aware of this for a long time.

 

I have no idea what you are talking about... want to be more specific?

JET

 

So I said it again..... you have an issue with that?

JET

 

wrong. What problems you come into is the stock cams. Remember, stock cams weren't made for boost, so the n/a design and overlap or duration is not the best match for boost on the stock motor and the turbo combo.

you could easily make power to redline with a set of cams..

 

unfortunately not. I think Tig488 might

 

I'll call your bluff here.... I will install any cam of your choice on my car. When the car doesn't make power to 6250RPM then you pay for it. A contributing factor is the stock cams... it's nto the only issue.

I may just use a aps system and send the turbo off to have the housing changed to like a .86 or so on the exhaust and .70 intake. thankfully housings are cheap. I dont really want to pull the engine too do twin turbos. Or sell it and put a holset hx40 in its place .. I will break 550-600whp with a single turbo next year.

 

This has proven true along with being a good step, I have seen boosted cars swap out to boost oriented cams along with additional tuning and make very good additional power.

Maybe something def. to consider JET, along with since Sam@GTM has those new Turbo Spec. cams

 

I am confused, why would you say the car would not make power until over 6K RPM's?

 

The stock cams are somewhere around .350 lift i think. Need something like a .520 or so lift with a 8-12 degree lobe sepration angle.

 

even JWT's most mild cam, the S2, will allow your boosted car to make power to redline. I can guarantee it.

I'd be willing to bet you could squeeze 20whp from your car, jet, with JWT S1's or S2's.

 

just wait and get the TN stage 2

 

Good idea. Wasting more money instead of waiting a little longer for a fully engineered upgrade!

 

Heh i wont the money untill this time next year for a turbo kit unless i rob a bank. The built engine is setting me back for at least a year.

 

IMO, when doing an engine build, it would be a waste to not go with cams in the process...they can obviously only HELP complement the motor upgrades going with more boost

 

You shouldn't even be considering any of the Single Turbo kits presently on the market. Either wait for the Stage 2 Turbonetics kit, or buy a TT kit. Anything else is just not logical.

 

I'm not sure why people don't bother putting them in while the engine is out and broken down. Cams should be a given in any form of FI engine build looking to make more power than the stock motor can handle. Everyone here suggested that Jetpilot install them with the build, and he chose not to. Now he's feeling the effects of it. At this point, even if he does go with a Stage 2 upgrade, or even a TT kit, he won't be realizing the full potential of his setup.

 

lol taurran im just thinking heh. I have to wait a year so by then i will decide for sure which route im going either twins or a single. The reason i like single turbos more is it is less complex and easier to install my self, as in the engine doesnt have to come out. I want to do cams when i do turbo it, by next year there should be more of a selection and hopefully prices come down. I can put cams in myself

 

the aps is a 3582 cartridge, and the turbine housing is not exactly known. at first i thought it was a .63 or .82, but i had a tech at the garrett booth at nopi look at it and he said it was pretty big, like .82 or bigger, but again i dont know for sure, i tried to measure the A/R using the formula and i think i got a .85, so its probably a .83 housing.

i thought about buying a new housing, atpturbo sells them for around 250, they have a 4 bolt, ext wg, 1.06 that would do good, longer spool, but more top end power.

wtf made 440 on the stock motor, then had it build and made almost 500 iirc.
