Turbo 258 Pt. 1

[<mail@xxxxxxxxxxxx>]

Two ways to go on this -
one being EFi - which monitors
the engine & takes care of mixtures.

The other is using a modified 4bbl. carb
on an AMC 1982 - 1988 Intake / Exhaust
manifold.


If you're going EFi - find the ECM from
a Pontiac Sunbird Turbo car -
check www.car-parts.com for one,
should be $35.00 to $65.00.

Get the 1992 Camaro TPI engine
harness / EFI which will be modded
to work - or - buy a Chevy Syclone
or GMC Typhoon wire harness.
Salvage yard Camaro harness cheap
or
about $250.00 for the new Syclone
harness.

This way - you have a proven Turbo
6 EFI system by GM that can be
programed for your particular settings.

this group is good to be on when setting up your
ECm (electronic control module).  Mike V there will
hip you on how to swap pins around for the V8 TPI
harness so it works on your I-6.

The exhaust manifold to use / modify is the 1987-1990
Cherokee 4.0 exhaust header. 

It is Stainless - should be
braced up - & a Turbo Mounting Flange added.

This is for a Javalin ?  You can use the 1999 or newer
Intake Manifold - upgraded design with a large plenum
and larger port runners.***********************
Buy it complete with injectors - Throttle Body - fuel rails
etc. out of a salvage yard or eBay. 

Ask on the Strokers list
and you can check www.car-parts.com.

The 1991-'95 cylinder head is best choice
for performance -
keep  cast iron exhaust valves or replace them
with Iconel - or Sodium Filled -
- check Manley Valves - I would
stay with a stock size & retain seat size.

Clean up with a pocket port..

Install new Teflon valve seals - bronze wall
valve guides if needed & I'd change
the cam to a mild Turbo / Torque cam and
replace the valve springs / keepers / locks.

I'd use the 4.0 cam retaining button to keep
the cam in proper position.

Figure your operating range from 1,500 to
5K rpm with  1,500 to 4,500 your asked for
range when looking for a Turbo Cam.
CRANE or another supplier should have
some offerings.

Go with a new roller timing chain & sprockets.


With this pgm. - you'll have roughly 300hp -
about what a health 360 would deliver without
all the weight hanging on the nose all the time.


Here is what you should use in that project
for a Turbo l:

Use a T3 .63 a/r turbine and .50 T04E hybrid compressor.

Less lag yet it can support hi-horsepower.
