Interm Engine Buildup.

[LOAF]

I am trying to do some research as I build my GL Vert.. I am currently working on the suspension followed by the body and interior.. My last phase will be the engine.. Depending on how money is.. I would love a Type IV... but as an intermediate engine I wanted some thoughts on the following..
I live NNJ so I deal with the rollers at the DMV emmission station.. That being said, some have suggested keeping my stock 1600 DP EFI L-Jet engine for this purpose and having a second engine for fun..
As far as maintaining my engine stock.. I really would like to extract some more power out of the L-Jet system.. I was hoping to increase the displacement to about 1.8 or 1.9 lt.. via differrent Piston/stroke combinations.. Haven't put thought as to which.. The problem I hear from people is that the valve sizes are to small.. Can't I invest in a shop to increase the valve size to compensate for the increase in displacement..
Also planned on a less restrictive exhaust..
WHAT or HOW can I tweak or replace the Air Mass Sensor to pickup the pace to compensate again.. Can I use some parts off a Vanawagon or other L-Jet Varient that Has a larger displacent.. will I havet to switch to larger injectors..

Don't want to break the back..but since I was thinking of having this engine rebuilt correctly, I wouldn't mine spending a little to have a nice (80+ hp) engine for fun and inspection..

Thanks and appreciate feedback..

Lot of looks..
Any insight..

I think that the problem you are experiencing is there isnt to many people that know how to make a HiPo Stock Fuel Injection Motor. I beliebe the stock FI is a very limiting factor.

Maybe some of the VW mechanics can validate this, but if you a have to keep your 1600cc motor, maybe you can bump discplacement up to 1679cc via machine in 88mm Pistons.
then maybe throw on some CB performance 044 heads with larger valves, maybe some 1.25:1 ratio rockers and a better ignition system. If the Stock FI could handle it, that should definitely get you the HP you are looking for.

Let me ask you this?
In NJ, is the inspection a Visual inspection as well as a smog test?Well if you want a Type 4, why not convert a 2.0 T4 using the Cali method?
This way you can use all you stock Type 1 tin and cooling and you will still appear to be using a 1600 Type 1. It is very hard to tell that it is not a Type 1 using this method. Only visual difference is the exhaust ports on the bottom of the heads instead of the sides like a Type 1.

When I taken my other auto's in for inspection.. The do pop the hood.. But most are looking for Non-CARB type parts.. ie.. Rice rockets.. with many bolt-ons.. Never would have considered you suggestion due to lack of experience with the type IV.. The Cali Conversion... Can you explain a little more.. Is this the one that you buy some pamphlet.. and with aluminum pieces you redirect the air over the engine.. I am on my work pc and don't have the site handy.. (something like Next Gen..)

Can I retain any kind of heating with this conversion.. or is this a fabrication issue..

As far as Jersey.. the do look.. But mostly to see if you have an exhaust... Not missing thing.. After that its time to hit the rollers and see how you do.. The visual isn't that taken that serious.. Depends on the inspector.. But like I said they are after more of the Honda crowd..

Thanks

Yes you use all stock type 1 cooling and tin, so outwardly, no one would not that it is not a Type 1.

For exhaust, yes you could keep your heat.
You have to modify some T4 heater boxes (you have to shorten them).
And then all you would need is a header from either FAT, BAS or LA Performance.

With a mild 2.0 Type IV no problems with overheating..
Just want to make sure..
I have heard that it is time consuming to build this.. but for mild engines not bad.. Could be fun..
How far can this set up be pushed for providing necessary cooling..

I met a guy with a 2056 t4 that had 130HP and was running the stock T1 cooling and he said he had no cooling issues what so ever.

You can also buy a T1 style cooling shroud from some of the different suppliers.
