go with a 2.2 you will be a very happy camper

Gil used to sell them for around $1300 been awhile

Rally Bob did a write up on a 160 HP 2.2 buildup maybe some one has a copy

wow you scored a 2.2 crank -- good for you

i would try to go for flat top pistons
you really have to have your act together with Pop Up pistons in an Opel

CR is not every thing try to shoot for a 6500 rpm torque motor

what ever you get about 6500 rpm will be cake

i picked up some nice rods awhile back and they came with Ross flat top pistons
they say ross375 on the underside

The rest of your specs look pretty good except the Cam and maybe the koni reds.

Yeah i know about them I have 2 sets

Those are Toyota 1.6 liter, 4AG, 20V (20 valve) Quad Throttle bodies.(the motor is rated at 165HP so a lot of people are importing front cuts and replacing there old 4age motors)

Those ones have been put on a custom manifold with extensions so they will work on a Toyota 3SGT (MR2 second Gen.)

i been goofing around with some in fact i just posted these pic earlier tonight on the MR2 forum

They are a pretty neat factory part. Each TB is individual with its own spring so it wouldn't be to hard to change the spacing.

well Brian hows the project going?

i decided to take the plunge

I have a 2.2 short block at the machinist right now

Hope to get it back sometime after the Holidays.

its just going to be a street, track day motor

next problem is coming up with a Head
Oh I forgot I need a front cover someone told me you cant get them anymore.

[davegt27]

I understand

I turned the 2.2 stuff in right before Thanksgiving and they said a few weeks

So I figure some time in the spring Ha Ha. that will give me enough time to pay back taxes on my House and save up enough to pay for the motor.

What's your thinking on the Head did you nail down that part of the setup?

I don't think there will be to much difference in tuning a 2.0 or 2.2.


I do plan to use FI. Either 4AG 20v Throttle bodies or some ORE Throttle bodies I picked up.
