Can I use t3 internals in an 86 GLHS t2 block?

[cj011]

well unfortunately it looks like the motor of the GHLS has to come out. I probally seized a bearing. What is the differences between the t3 and t2 block? Can I use the crank, rods, and pistons from the t3? Thanks, Chris

You can use the T3 pieces, but you have to get a common block. The T3 crank will not work with the stock '86/'87 block. Just grab yourself an '89+ 2.2/2.5, gut the engine and take the new(to you) block and your T3 internals to the machine shop to be machined and assembled(if necessary). With the common block you'll be able to push more power through it and you'll be saving your GLHS block(numbers matching?) for a future restoration if desired. I sure wish I had that crank when building my engine...

Can I use the t3 block? Life would be really easy if I could just take my t3 short block with the t2 flywheel and drop it in?

oh yes, I forgot to add t3 block with SOHC head.

opps, i have been correct on calling it a t2 block instead of t1

You have a couple of problems to contend with - the R/T block doesn't have a hole for the distributor. Even if you put one there, the I-shaft sprocket has the wrong number of teeth on it and would spin the distributor the wrong speed, so you would need a round tooth cam sprocket or int sprocket to work on there. But, for the bigger sprocket to fit on there, you need the other front seal retainer.

Also ... pistons are different, it'd be an interference engine unless you either notched the pistons for clearance, or used a G-head.

You're probably better off getting a non-t3 short block to use!

Where are you?

yup i have received alot of info saying that the t3 block will not work for the same reasons. tomorrow i will pop off the oil pan and see if a rod bearing just tightened up. if so, i have a new set of rod bearing sitting on the table. that will just be a quick fix hopefully. if i just had a place to work on my car, i would drop in the t3 motor and tranny, but i live in an apartment complex. oh yea, dan i live in hawaii. if the rod bearing attempt doesn't work, then i will have to track down a 89+ common block and go from there. i really don't want to go through all the trouble of going the common block route because i will have to pull the motor somehow and put back a sohc motor when i have a dohc sitting in my kitchen. decisions, decisions. my head hurts.

hey guys, could i use the tIII DOHC head with a t2 block that has a distrutor? Would I be able to run the electronics for a t1 so that I don't have to completely rewire the car in order to get the distributorless ignition yet the added benefit of 16 valves. I would definately have to get a recalibrated ecu or standalone management. Is this possible or is there large differences of how the tIII head and tII block would line up? I apologize for the general question, but I had an idea that was floating around that I just had to ask.

there' s more info on this in the 16v section but...
the head will bolt right on
you need to mess around with the belt tensioner
I don't beleive there is a intake manifold that'll work with the stock dist.
I lot of people run them off the cam from the side of the head
You'd at least have to upgrade to TII electronics (which if this is going into you GLHS you already have, people get too caught up on TII having to be forged or common block but as long as it has a blow through intake for electronic purposes it's a TII)
swicthing is easy if this even is for a TI car
Yes a calibration would definetly be needed
plus a ton of other work if this is going in a GLHS

[cj011]

just to make sure, does the GLHS have t1 or t2 electronics? I know that it has a t1 block, but not to sure about the electrical aspects. in regards to the intake manifold, I am would end up getting one fabricated to i can spread out the power band to save head gaskets and also clearancing the radiotor wouldn't be such a pain. I am thinking along the lines of big plenium, short runners.

[cj011]

if people have put the distibutor in the head, then wouldn't I be able to still use the tIII block. So that I don't have to worry about getting tIII crank gears onto a tII block.
