I've been playing with a G13a and Megasquirt in a Samurai. But the motor has developed a head gasket leak, and the compression is only about 150 on the other three cylinders. I need to decide if i want to stick with this motor i or go shopping of a G13BB. I know the g13bb has more HP stock, but there are a lot more parts around for the g13a. Way more performance parts around for the g13a. I'm looking for power under 5,000 RPMS.

I'd love to hear some input!

What parts are available for the A that aren't for the BB, performance or otherwise, and how many of them do you need to bring the A power up to BB spec?

I would go bb because it makes more power (and more is available easily), is more modern and more current

the g13bb is the most desirable mill for reasons related to ms control. it has all the timing bits for full sequential injection and cop/ cnp multi-channel ignition.

most of the aftermarket parts required to swap a g13b or ba to a samurai are related to mounting, induction, or exhaust. you have the mounts. the modern throttle body is better than the best aftermarket induction set for the g13ba. and the exhaust manifold for the g13bb is easy to modify for the samurai exhaust's system so it wouldn't necessarily require a new exhaust manifold.

considering that your gearing would benefit more from low end torque, the g13bb could be tuned most appropriately. :wink:

Great link. I didn't know 3tech sold cams for the g13bb. I'll to check in to see what if does a grind suitable for my application.

The biggest two factors i thought the g13A had was availability of high compression pistons, and 26cc more. I thought that would probably give below 3k power advantage to 8v motor.

However The link you posted talks about possibly using GT pistons for high compression in the BB, but googling a couple vendors and looking at GT pistons on rock auto i've only found 9.5 to 1.

I actually have g13bb trigger wheel installed on my g13a, and its working well. Not installed, but I think i have a cam sensor figured out and i have LS1 coil packs on hand. However, Not really sure how or if i would ever get to sequential.

If I go with the G13bb i'll buy g16 intake manifold and header. That would get me the 45mm throttle body talked about in the link from suprf1y. I just need to find out about the high compression pistons and cam.

I missed the MS part. T3 is right about that.

I calculated the GT piston compression ratio for the BB, but I can't recall what it was. It was over 10-1 though, and you also have the D16 piston option viewtopic.php?f=16&t=61095 which can give you 1mm more bore, 1334 cc, and any compression ratio you want. I have a set in stock.

The cam mentioned in that thread is an excellent torquer type cam.

It looks like the g13BB is probably the better choice. From reading your old post i think you calculated the compression for the GT pistons at 10.6-1. Are you saying you sell the GT or the D16 pistons?

I'll sit down after the kids go to bed tonight and try and list all the parts i need and unknown/possible issues. I need to make sure I wont need to spend a lot of time looking for hard to find parts, or fabricating a bunch of one offs. I'm a lot more limited on free time than funds.

I sell the modded D16's at any compression ratio you want down to flat top
