2 those who have/know sohc vtec swap well

[XxLuckyLisaxX]

that sounds too complicated for me myfirst4thgen

But guys thanks for the help really i appreciate it, so i should buy the crx si tranny and if the swap comes with a tranny ill sell it.

So Ami when u say MPFI conversion that means i also need to buy all the components for that also, right?

Just curious Ami do U or Jer know how to do the vtec wiring and harness wiring, i know that everyone i know has not taken the time to learn so they tell me if im gonna pay them to do my swap i still will have to take it somewhere to get it wired and i'm like......uhh no.

I have a question in regards to the ecu to use. I just did my sohc vtec swap last weekend in my 91 Si. Everything is good, using the 91 Si tranny and intake manifold. Oh yeah, I did the D16Y8 not the D16Z6, so I can still adjust my timing. The Si dist bolts right up the the Y8 unlike the Z6 which requires notching. Anyway, I am using a PG7 ecu right now. I dont have vtec hooked up yet because I'm waiting to either get the rpm activated window switch or a shift light with the switchable pills. Anyway, whats the power differences between the PG7 and the P28 (is that right?)?

I'm not sure of the gains between the PG7 and the p28, but i am almost positive that the engine will run a lot smoother and the way it should with the p28 because thats the correct ECU for the engine.......

well if that's the benefits then BOOO!!! The car runs smoothly, idles smoothly and is pretty quick as it is. Can't wait for vtec hookup. Last night I put a 91 Si two cars back.

Nice, well, good to hear that its running smoothly, i guess just buy a MSD RPM Activated Switch......

damn right. put a HP Racing header from my 88 4th gen on it today. Anyone wanna buy a 88 hatch with WW kit for 2300? I live in NW Florida. Still has original 1.5 with 142,000 and DPFI. Runs like a dream though.

Is the HP Racing header any good? cause i've heard they are rated pretty well.........

I have no seat of the pants feel reply or any dyno results but fitment, welds, and aesthetics are great. I have the chrome versions which burns to a real nice golden color with some "blueing" in high heat areas. Truly beautiful.
