What to do?

[93BoxRyder]

Just found the site and im likin what i see...Ok so i have a 93s10 with a 2.8 and im going to tear it down and rebuild soon and i wanna get the most power possible out of it. Im lookin into gettin the stroker kit and a pretty big crane cam from ARI also going to do the obvious stuff like headers etc. and also considering installing a small turbo but nuthin crazy just like 10 psi max jus wondering what else was out there that i could do.
any info or suggestions is much appriciated.
thanks guys

does the s10 2.8 have the highoutput heads?

if not ima be taking a set off my car soon.... the flow a little better (larger valves)then the non-HO heads... or you can do an engine swap/topend swap to some alum 3100 heads, but then youll need to get it tuned and such.

A 93 should haave the HO heads. If I were you I would use the money from the stroker kit to buy a 3.4, you'll get more power for less money.

I just might have enough parts here for you to do the stroker kit In fact may even have some stuff here to do a turbo kit on the cheap :P

well that would be awesome lol...im not sure on the heads...dont kno too much about the 2.8s...when stroke it i was wanting to do the .60 over bore
and the Crane PowerMax F-248/3334-2-12 cam....i dont kno much about the 3.4s...well i dont really know any thing about em lol...whatd they come in? and how "hard" is the swap? if i do get a 3.4 id probably stroke it also since ARI sells a kit for that too lol that is...unless anyones had bad experience with the company?

the 2.8/3.4 in a RWD is basically just a swap, just about everything should just drop right in, can use your old 2.8 distributor, and such, or swap it with the ECU and go DIS/multiport fuel injected (camaro top-end) (what injection is the s10? TPI?)

from everything ive read, dont even look at ARI's website, it will rot your brain.

The 3.4 came in the 93-95 f-body's. All you'll have to do is switch the intake to yours and drop in. If you noticed on the ARI site it says they dont sell the 3.4 stroker as a kit, so all they are going to do is send you one of these engine's anyways. A friend of mine had a 3.4 with roller tip rockers and headers in a s-10, it ran a 15.09. But if you want serious power you need to just go turbo.

sounds like a 3.4 is the way to go? and i assume...theres more performence parts available for the 3.4s? and yea i wanna get as much power as possible outta which ever one i use so some type of forced induction along with a cam and everything possible will be used...thanks for all the info so far guys

What kind of budget you have for the engine work?

[hookdonspeed]

the 3.4 use alot of common parts as the heads are the the same casting(if they are the HO heads)

rockers, cam, etc can be swaped between the 2 if your not running DIS, if you are you need to be sure it has the magnet for the cam position sensor

[93BoxRyder]

i dont really have a budget lol...just a matter of how long it take to get the money...but im not in any hurry so balls to the wall full on build lol...im going to be working on the engine while im workin on a frame for the truck so i wont have to worry about down time u kno...

rockers, cam, etc can be swaped between the 2 if your not running DIS, if you are you need to be sure it has the magnet for the cam position sensor

Only to retain the SFI function. The SFI ECM's will run the engine in batch fire if the cam signal is absent. The ICM is asking for the same signal from the ECM for advance/retarding timing as an HEI distributor.

Hi there!

An ICM and a distributor are 60 degrees out of phase with each other. You can make a DIS ICM work on a MPI ECM with changes to the chip (min. and max. advance, and reference angle) but it won't work by just wiring it in without the programming change. Electrically, you're right -- the wiring isn't a problem.

But weren't the GenII's MPFI and DIS?

[jwvess00]

Hi there!

Yes,GenII engines were DIS and MPI. No GenII engines had a distributor that I've seen.

I think I mis-typed what I meant:

You can use a distributor on an ECM that wants a DIS system, or a DIS system on an ECM that wants a distributor (assuming the crank trigger is present) but it requires a small programming change to account for the 60 degree timing offset between the two. The two systems are electrically compatible.
