What would you do?
As some of you guys may know my 79SA died on me a little ways back.I lost compression on my rear housing. I pulled the motor apart and fould i had stuck seals and major flacking on bottom half of the housing. The oil pump chain was so slack you could almost touch the chain together. I found another good housing i had from another parts car i had, so i would just need a full rebuild kit which i found on Atkins Rotary for 800.00 and some change.While apart i was thinking of a port job.I would like to go with a full bridge but i have read that doing this would take the life out of my engine.I like the brap that i would gain plus the xtra hp.Going with a street port would give a little more ponies but not much.Turbo would be sweet but i have no clue and it would be real costly. If i sell my 12a parts, Racing Beat carb and intake and header and good housings and irons, i could use that money and buy a 13b. Then i would have to get a new intake and carb, header.This is something that does not have to be done overnight, but i was wondering about the pros and cons. Money is some what of a issue but i have plenty of time for this build. Can you guys give me some thoughts of what you would do. I would like to get about 250 or so, close to 300 hp if possible.:scratch:

Get the 13B and carb it, sell the remaining stuff you can, and maybe do Streetport. I don't think turbo is good on a SA/FB engine because of having to rebuild them 30-35K from what I hear. A carb'd ported 13B in your SA would haul ass with headers and all. Just my 2 cents...

You can tell from my signature that I agree with bmeyer!!!!
|
lightly ported and carbed and exhaust 13b is powerful in a first gen
|
What i like is the simplicity, you don't have to be an expert on
FI or turbo's to keep it running!!!! |
If this is still around, I would think of buying it and doing the swap:

Yes the 13b idea is sounding really nice.The only problem i may have is securing that 13b. I have done searches and found a bunch of 13bs on online car parts.com but they have over 100,000 miles and would have to be rebuilt. The prices range from 450.00 to almost a thousand. That means another 800.00 or so to rebuild not including carb, intake and header. How much quicker would a 13b be in a Sa than a FB? The search is on!

just put a 350 in there and be done with it.

-se rotating assembly between 12a irons, add in a modded nikki (atop an rx4 intake), long tube header, and decent serving of large streetport. This my friend, is a recipe for awesome.

ah I have an engine from an s3 and am going to boost it, should be fun the sa 12a is in a climate controlled spot so if I ever want to go back to all orignal ... but thats just my two cents ... or say screw it and go for the 13b ... it's a good number lol ;)
