#31607, "Just installed my ported and polished head and intake manifold"


          

Umm.. in a word - FAST!

Two questions
1) I am currently burning off the 89 gas -- seems to run fine though - odd.

2) Is the computer adjusting for this even though I have a higher compression ration?

A comment:
I need a bored throttle body in a bad way -- the car starts to scream at 4500 all the way up - this is really a top end mod but damn is the top end nice.

Anyways -- thanks for the help guys.

Isn't there different stages you can go with??? as far as P&P goes?

What stage did you go with?
How much did it cost?
How would this do with about 15 psi???

Well - I got a pretty good deal on the port and polish plus 5 angle valve job - it was 350 -- that including disassembling + reassembling the head and 2 new valves.

I guess you would say I got a stage one -- I told him I did not want any error codes or funky idles - so he opened it up / smoothed it out quite a bit though -- I can probably post some pics.

As far as cost for you -- haven't a clue - on a side bar I do have an extra cylinder head lying around now -- so any takers???

Complete - cams and all - which means you can send your cams off to be reground whatever.

Let me know guys.

Mitsu says 87 octane is just fine.

The computer will adjust the fuel mostly based on the a/f ratio at the o2 sensor. You should be just fine with the stock feul system even if your running a very high compression ratio.

My question to you is - what is your compression ratio? If you just did a p&p, then your compression ratio is stock - 9.6:1. If you had the head milled then it would be higher. You made no mention of milling the head...just the p&p. No matter what compression ratio you have the stock fuel(computer) system should be allright - as long as you are NA. If your compression ratio IS higher - you will have to run higher octane feul. Make sense?

Milled the head .030 -- not sure what the exact compression ratio would be on that but I am guessing 10.2?? Someone have a calculation to figure this out?

As far as was it worth it? Yes -- nice little umph --- I would not do it if you weren't already going to be changing the head gasket or doing the timing belt though - its A LOT of work.

Oh on a side note -- I blew 180 on all four cylinders when I did my compression test emoji

About 10.4:1 compression. I'd run premium from now on although it might not be absolutely necessary.

I've got my ported cylinder head on the car now as well. I screwed up and got the wrong cam profile and messed up a valve seat on cylinder #1. Although you couldn't tell from the compression or leakdown test. 200 across all 4 and 12% +/- 2% on the leak down, but that was with 150psi air pressure.

I've got my head milled to produce 10.6:1 compression. Port matched the intake and exhaust manifolds and ported the intake manifold. I've also got 1mm oversized intake valves, 3-angle valve grind, Crane valve springs, PT rockers and lifters.

The cams should be back in the car on the 13th or 14th and should have new timeslips within a week of that. Given that I can just touch up the valve seat and pop the cylinder head back on quick enough.

It's become a pretty serious race to see who can get into the 14s first.

Yep. I would run the premium as well - You should be fine on 89 though.
