Does this 3.4 DOHC rebuild kit sound like a good deal??

[fathead45]

Well i have been wanting to bore the block .20 or .020..sorry people have told me different. But i am doing a complete teardown and rebuild. I found this kit and wondered if it was a good deal and if i was missing much.

I want to do a slight performance upgrade and get some more pep. im kind of on a 800 dollar budget..but i may go over that

Im still hoping to d some PnP work, heads will come later, and i hope that ben finds the 70mm tb.

Here are some pics of my rebuild and teardown: www.cardomain.com/id/fatheads34

Matt,

Main bearings
Cam bearing
Timing belt
Oil pump
Freeze plugs
* Gasket set contains the following gaskets:
2 head, 6 exh manifold, 2 water outlet, 5 o-rings, 24 valve stem seals, 1
plenum,
1 timing cover, 2 oil drain plug, 1 rear cam cover, 2 valve cover, 2 int.
manifold,
1 oil cooler, 1 oil manifold, 2 o-rings, 2 EGR valve, oil pan, timing cover
seal, water pump,
2 cam housing, 1 rear main seal, 5 interm shaft seal, 2 cam rear cover
This is all the gaskets required to rebuild the engine.

what kind are the pistons?? Silvolite

> are the gasket fel-pro? No, Corteco. Felpro additional $25.00
> do i get the timing belt acutator, tensioner, and idler pullies? Timing Belt only
Manufacture recommends replacing the head bolts #27324 $20.00 set

We accept most credit cards.

Freight by UPS ground: $16.00

Thanks,

Get felpro, and you will want a new timing chain and tensioner. The oil pump for the DOHC should be all you need. The higher output oil pumps are actually less output than the stock DOHC one. Also, you need the timing belt parts, obviously:P

It is .020, or .5mm that you are talking about. The cost is pretty good, close to what you would pay if you ebayed everything.

[fathead45]

ok, thanks for clearing that up.

someone told me that if i just do that, it will lower my compression ratio. they said to have the machine shop do a 10:1 CR or 10:? something. how would i do that. or would it even make a difference?.

II have all the timing belt parts, i have the tensoiner, i know i will need a new chain.

thanks for info

[SappySE107]

If you go larger cylinders, it increases the compression ratio a small amount. Decking the heads some will raise compression but you can quickly turn your engine into an interference setup. Depends on if you want the clearance in case the belt snaps. Our setup is supposed to set the cams so no valves are open if the belt snaps but inertia will cause them to still spin depending on the RPM it goes. 10:1 will require different pistons than that kit provides as well, or a lot of head decking. I dunno how much you would have to deck it though to get there.

[fathead45]

well i think i will just say fck it and get the bigger pistons. it cant hurt me. esp for when i finally get some money and i can have you do some heads for me

Find anything new about those TB plates?? And how much again for PnP or upper and lower intake??

[SappySE107]

I told Kimmo that I still need those plates but nothing yet. Im going to try out boring the hole next week and see how much work that is. Im not sure on pricing anything yet for plenum work since its something I need to do first all the way through and see how long it takes. The TB alone though shouldn't be much as long as the boring process goes smooth for me. Lower intake is going to be about 70-75 port matched to the plenum gasket, casting marks cleaned up and measured throughout (not just a simple "its matched, good enough" mentality).

Ill have pictures and measurements and all that within a months time I am hoping. I am catching up with a 2.0 mitsu head now, a 3400 plenum, and a 3400 lower and set of heads that need just a bit more work, plus the DOHC heads that im redoing for a fiero. All that plus setting up my business so yeah...im gonna be busy for a few weeks Ill have final pricing on my site when its all said and done. I do plan on discounts for sets, so that 70-75 for the lower alone will probably be cheaper when done with the plenum/TB.

[Gemmer]

wow ben, looks like buisness is going well

Are you going to be dynoing your products seperately? That would be interesting to see.

[SappySE107]

Well, thats the idea, or at least dyno baseline, then the TB alone, then the TB with the upper and lower ported. DO that for multiple engines and you can see its gonna get expensive. Im sure it would boost sales though, especially once that damn flowbench is going. Its soo close too, just need the cylinder sleeves so I can bore the holes in the metal and plexi...and seal her up Business is good for not going public yet with the site:P

[fathead45]

well ben i think your business will go well, esp with the prices you have. Im prob gonna go with you as soon as find out everything. i can wait anyhow...gotta get this engine built, lol.

What would you expect to see in HP with what i want to do:
-bore .020 over
-13 degree retard
-Pnp Upper and Lower intake
-70mm TB
-k+n filter w/ ram air
-ud pulley
-8mm taylor wires

I want to do something to the tranny, but i dont know where to get gears, high stall converter, shift kit, and other things. any ideas?

compression

u increase compression when u increase bore size? out of curiousity, what would 40 over do if u have 9.25 cr? i don't plan on going this netime soon but i do have plans for it eventually.

another way to increase cr safely(i believe) is if u have a 91-95 engine and swap in a set of 96-97 heads with smaller chambers. kind of reminds me of old school when swapping a 72cc with a 64cc 350 heads. of course there were other reasons that was popular other than a slight gain in compression. i don't think u will have to swap intakes, but the exhaust manifolds are different due to port design.

and while i am on the subject of swaping parts. if some1 did swap 96+ heads on a 91-95 engine, which set of cams would be better? i know they each set have slightly different specs. so hmm.

[SappySE107]

I have no idea on the HP when you finish the engine, mostly because no one has dynoed the 13 degree retard on the cam timing. When RAT was around, I think they claimed about 8 hp at the wheels from the TB from dynoing it, but its been soooo long since they were around I may be wrong. Until someone goes to the dyno with the cam timing, its impossible to even guess.

I don't know what the new compression would be, i just woke up and math formulas don't run through my head very well till I am fully awake:P I know it increases because you add volume to the cylinder on the over bore, and then compress it the same height as before into the same volume in the head that there was before.

im gonna look this up in desktop dyno for the cylinder volume.
558.26cc stock
570.66cc at .040 over (1 mm)

Im gonna ignore the head gasket for now. Stock would be 9.54:1 compression
Bore over would be 9.75:1. So its about .2 increase. Thats if the pistons have the same deck height and valve relief volume. In case you were wondering, its about 4.5cc for the stock auto piston valve relief and the 91-95 heads are 54cc.

96 heads give you 51.5cc. As for cams, the 96 cams are gonna give you a little better top end and hurt bottom end some. There isn't much difference in them that im aware of, just timing.

[fathead45]

thanks for the info ben...i maybe dynoing in WI this june if it is done by then.

[fathead45]

well i have 1 qoute of 177 for boring and honing to .020. if i dont find cheaper i doubt i will be doing that. Porb. just have to get stock size and deglaze and put the new rings on.

im gonna call around some more.

[dykz34]

If you are going to rebuild an engine, I would HIGHLY recommend that you do not cut corners. It will only hurt you in the long run. Why are you rebuilding your engine anyways? AFAIK, it didn't blow up, right?

[fathead45]

No it didnt blow up, the intermediate shaft sheared off and broke the timing belt.. Everything else looks good.

I dont think it is cutting corners if i just go with NEW stock size pistons and rings. It just give me that little extra that the boring would do. If i was to use the old piston and rings then that would be cutting corners

Im rebuilding b/c my current 3.4 has about 185k and it hasnt ran right in about 8 months. Get the damn code 32 everyday, replaced everything i can. I have about 900 in this current motor and i just dont trust it anymore. I want a more reliable one.
