I hope that "day dreamer" comment wasnt directed towards me.

Is there a motor mount kit for the 302 to be installed in a 260z?? Also what manual tranny has the best gearing from the factory?? Thanks again for the quick response. Braxton

I was wondering what years, and models the 302 EFI was put in. I was considering an ls1 swap but the engine and tranny combo was over my budget. Second question, how difficult is the wiring for a 302 EFI in a 74 260z?? Would I need to make something custom or would it be easier to find a late model Z harness that has fuel injection?? Thanks in advance. Braxton

There are two different blocks for the 4G family engines. One is the Narrow block that most are familiar with, and there is a 'wide' block that little people have known about until recently. Enter the B2600. Mazda's B2600 had a Mitsubishi made 2.6l bottom end in the 87-88 trucks. This is the same as the Starion 2.6l, but the kicker is that they all share the same bellhousing housing bolt locations. So in essence any Mits motor with the wide block config will bolt to any B2600 trans. Now the B2600 is an R series trans, the same as the TII and the FD. Swap the B2600 bellhousing to the TII or FD trans and bolt to a wideblock 4G. This has all been recently discovered, there are a couple people in the process now of hammering out the fine details. The bonuses are a couple good things. Like a 240mm clutch setup as opposed to the narrow 225mm setup. The best to me is the fact it's built out of cheap parts and less custom fabrication.

What all electronics would I need for the engine then because the yards here will charge for every sensor, switch relay, terminal and wire??

If I was to get an ls1, the motor mount kit requires the use of the ls1 mounts as well, Correct?? On that topic, the website for the kit doesnt seem to be able to use the stock a/c location, correct?? Then there is the electrical issues of wiring a ls1 into a 260z for example. How difficult is that task and would you be using the ls1 MAF setup on the 260z chassis wiring or would you have to create some custom harness OR is there one thats already made?? There are intake manifolds out now for the ls1 that make it carb'd. Would that create less of a headache in wiring but decrease fuel economy?? I have tons of questions but I am getting them all answered from the generous input of you guys. Thanks again in advance. Braxton

Awesome. I love how this board has such quick response time to questions and how the answers are so detailed and informative. I should have bought a Z forever ago.

I luckily or unfortunately have done about 9 4g63t swaps so far in the two years that I have dabbled in cars but the biggest concern for the cost of the swap intially and then later on having a good starting point with a block that has large aftermarket support as well as ease of swapping.

I am admittedly very new to the SBC carb'd scene. I think that the motor in the 74 that I am restoring is going out. I was interested in trying to find a temporary solution with a good junkyard motor in the form of a SBC and a JTR mount kit. What would be a good motor to look/ask for at the yards that would be good for my short term use of ease of install and then also later on when I get more money together for the removal and aggressive build would still be a great starting point. I have heard good things about the 350 with 2 caps or something but what cars would that motor come in that would make for the most economical and simple install. Also if you have an alternative motor suggestion feel free to voice your opinion and explain why and what cars that motor would be found in. Thanks in advance. Braxton

There is a 2.0 4g63 that came in several mighty max pickups. There are fairly rare and the tranny that you would want to mate with it would not be a StarQuest tranny. The StarQuest tranny is brittle past 350hp and like one of the earlier posts said there is a way to mate a Mitsu bellhousing with I believe a Mazda B2000 tranny. The myth of the crankwalk in 4g63s is commonly blown out of proportion. I have had several high mileage 7 bolt 4g63 Eclipses that have shown no sign of crankwalk. Also if you are serious about attempting anything Mitsu lemme know and I can give you some items to look for at the junkyards to make a low dollar 2.3 stroker kit.
