Help make my mind up: Trans Swap/Rebuild

[ljackson]

I'm thinking about going to the t 5 also. If you decide to go that route, here is an article I found online that talks about changing the tail housing to fit better with a bench seat. It also addresses moving the speedo gear.

Thanks for that link. I'd not seen that article before. Pretty accurate too. They show how to combine an S10 tail housing with a Camaro T5. That way you get the shifter up in front of the bench seat. It is the same exact thing I did, only I included a rebuild of my Camaro T5. My swap does not include the shim because I didn't need it. That's only needed for some swaps. Here's my T5 rebuild web page.

My only comment is that most V8 Camaro World Class T5s have a 0.63 OD which is pretty tall for a truck with 28" or 29" tires and a 3.73 rear diff, unless you have a lot of HP up front. I calculated RPMs using a 0.63 OD gear, 28" tire, 3.73 rear diff and came up with 1833 RPMs at 65 MPH. That's pretty low RPMs. A 29" tire would have 1770 RPMs at 65 MPH. I was worried my 250ci would bog on any sort of incline so I opted for a T5 with a 0.73 OD gear. The 0.73 with a 28" tire gives me 2124 RPMs at 65 MPH and 2051 RPMs with a 29" tire. I was much happier with the slightly higher RPM numbers.

Lugnutz, that makes sense. I will consider that. I have the original 283 that we rebuilt.

My neighbor, literally next door has a t5 from a 92 s10 that I just found out about today. Issue is, pulse speedo. What are my options for getting an electric speedo in my truck? Has anyone used the pulse speedo t5 and also swapped their speedometer?

So that 1992 S10 T5 will be a NWC unit. It will have either a 0.72 or a 0.86 OD gear. The 0.72 is the better choice.

It can at some future time be converted to a cable speedo by swapping an S10 tail housing that has a cable speedo connection.

To get your speedo working again for pulse (VSS) output units, you can
1. Buy modern gauges
2. Use a GPS instead
3. Cable-X conversion box

Some modern gauge sets are very expensive, so watch your budget before you jump in that direction. Nice thing is that you can just use a GPS until you save th money needed to go modern gauges or tail housing swap.
A recent thread showing gauges is HERE.

Here's a digital gauge I saw last fall at the Charlotte Auto Fair that looks like an original gauge when the power is off.
