Ok this question is for people that have the Alpine Turbo Kit(Random)
I wanted to know if the 5th injector thats included with the kit is larger or same as stock.I believe the stock injectors are 240cc?(around there).
Also i recall Cheuk saying that a set up like Alpines is not a good idea cause theres a chance of running lean in the #2 cylinder.
Should i just upgrade all my injectors to 440cc?
Random you also said the head gasket spacer is not reqired if your running 7 or 8PSI.only i your going over10PSI.
Gavin at Alpine said that you would have to install it cause the stock compression is too high?My 1.8Litre is 10:1 ratio?
Plus if you install it he said it brings it down to 7.8:1.Thats very low if you ask me?
What do you think RAndom
Sorry for all yhe questions smile.gif smile.gif

 

the 5th Injector is a 330cc unit.

The head spacer is required for above 10 PSI. OnPol ran a turbo at 10 PSI with just 4 larger injectors and a S-AFC. You would not want to try above 10 PSI without re-working the internals anyway, so you would go with decent pistions that lower the compression.

The Alpine head spacer is Stainless Steel. I do NOT reccomend it, as it is weeping oil into my coolant because of a poor seal. Per my conversations with Alpine, they stated that the head gasket only lowered the compresion one full point. So it would drop you down to 9:1 rather than 10:1.

If you can swing it, try to get a discount on the alpine unit by having them leave off the Uni-Chip/boost module and 5th injector. Then invest that money in a HalTec setup with 4 440cc injectors and a decent blow off valve.

 

Random,

Dont you need the unichip module to run boost or would the haltec setup fix that problem? WAs just wondering thats all.

hey random, how much did the whole turbo deal cost with installation and all? do u think it was worth it? Does it have a lot of problems? Would u recommend any other brand if there is one? thanks.

The Uni-Chip boost module is not required. Onpol was able to make his turbo setup work with just an SAFC. A Haltec would be the better way to go though.

The Alpine turbo is currently $1900. This does not include exhaust piping, but it does include a downpipe. If you are not mechanical minded, and don't want to build your own turbo kit, it is a good way to go for a decent price.

There are no other turbo "kits" out there to reccomend.

If you want to build your own, it will run you about $1900 minimum.

 

Random!
When you say the kit doesnt come with the exhaust piping, do you mean the exhaust maifold?

 

It doesn't come with a cat-back. It has the manifold and the downpipe that will connect to the rest of your exhaust system, but it doesn't have that exhaust system (cat, muffler, pipes that connect them, etc...)

 

It comes with the log manifold, and the "downpipe".

The "downpipe" is what you use to connect to a/any exhaust system. It does not come with an exhaust system, but it does come with the Manifold and downpipe.

 

Random!!
Thanks for all your help.
BTW,im going to use the set-up which you recommended to me where im just going to upgrade my injectors to 440cc.
Now my question is which injectors do i ask for when i call RC Enginering.What i mean is do i ask for 440cc High Ohm or 440cc Low Ohm.
Im not sure what the difference is but i think the Low Ohms are if your planning on running a Haltech and stock cars come with High Ohms injectors already?
Or can i run 440cc low Ohms and have no problems as i might in the near future install a Haltech.
I also do have an upgraded 2nd Gen Turbo Talon Fuel pump installed in my Tiburon which should work well with the upgraded fuel pump!!!!!!
I'll just keep the 5th injector and install it if im running 15PSI or more of boost if my 440cc were to max out.?

 

If you are going to keep the stock ECU, you must go with high ohm injectors. The haltec will work with High Ohm injectors, it just works slightly better with low ohm.

RC-eng is the way to go for Injectors.

I would reccomend replacing the 440cc units with larger ones if you ever go over 15 PSI, rather than the 5th injector. Or just order 550's or 600's to give your self some "fudge" room to tune for high boost later. However....MONDO injectors will not like to "eek" out very small amounts of fuel at idle...so I would not reccomend any larger than 600's. OnPol can get away with the 850's he's using as those will be low Ohm with a haltec...
