DOHC Performance Build

He moded a 96 front header to fit the rear buy cutting the head flange off and re welding it on upside down Its like how the 95 guy use a front as a rear and run there own custom turbo tubing.

The bolt pattern on the later heads is off. If you put a front manifold on the rear head, it would point the wrong way. That's why I had a new front manifold butchered and a new flange welded on. I also have two spare flanges in case I want to make a tubular manifold at some point.

I might buy them off you I need headers wicked bad!

I already have both a 96 and 97 harness with computers, an AeroForce Interceptor scan gauge, DHP, and HP Tuners, so at this point it's going to be OBD2. For the 95, the wiring swap doesn't seem too complex.Tim

Derr, im retarded, i knew the front doesnt bolt to the rear on the new heads...I must be slippin'

as for the harness swap, Its not hard... lol if my monkey ass can get it running its not hard. ('96 harness/ecu on 95 motor).

I promised pictures when the short block was assembled and here they are. I didn't get too far on the LQ1 because I've been working on the S2000. I managed to get the front cover on and the crank balancer/pulley on.

And here are the heads. New valve guides all around that have a retaining disk machined into them, a valve job, everything cleaned up, and the WOT Tech 4.6 SOHC valve springs. It seems the spring pressure is up dramatically over stock. These shouldn't have any issues with valve float.

Yesterday, my Monte got a hand wash (first time I have hand washed a car in years) and a new yellow top Optima (the old red top was beyond dead and it wasn't coming back). It's now pulled into the garage and ready to go.

Current plan of attack: I'm towing my S2000 back from the exhaust shop today (had to put in a cat again to get past emissions). Once it's home and the trailer is returned, I'll get to work on the Monte Carlo. 1st step, hook up a rear parking brake. 2nd step, assemble my new 2 ton Harbor Freight transmission hoist (probably going to use it for the front subframe). If I'm lucky, I may have time to start either removing the wiring harness or interior today. I'm not looking forward to either task, but hopefully I at least have all of the parts I need.

Where and how much were the forged pistons?

[timg]

The forged pistons were from CP. IIRC, they were around $1200. Here's their spec sheet.


Tim

[poncho racing]

Does that 1,200 price include the rods as well I forgot to ask about those?

[pocket-rocket]

I doubt it since they will be custom one offs and not an off the shelf item.

Nope. The rods were again around that much. There are cheaper options out there, but you're probably still looking at $1500 for forged pistons and rods even if you do use a cheaper option (narrowed SBC rods).

Good news and bad news. Good news, I started working on everything. Bad news, the ARP head studs won't work. They're about 1/2 and inch too long.

Tim

[SappySE107]

do you know what part number you used? I have head studs but you can't use washers with them.

[timg]

I used part number 204-4202. That kit is for a VW Golf/Jetta 1.8L 16 valve. They screwed in perfectly and everything looked okay until I put the heads on.
