engine build up questions

Hey..
Just checking if someone could lend a hand on answering some simple questions.

I'm looking to rebuild an engine for my turbo project. I'm having problems finding the correct head gasket. I found one made by fel-pro for the sohc.. I'm not too sure if it will work. Any suggestions on this or another HG?

Also, having problems finding ARP head studs/bolts... found some for the Miata.. would these be the best option?

One more... Is it worth while to do the valves and springs? I'm not looking to build a race car.. But I would like it to last a long time.. with moderate abuse.

FYI.. big 16g.. around 200hp is the goal.. Will have a fab'd ex mani made soon.. will have pics if anyone is interested in this set up.

Thanx guys!!

ive used this gasket set but it was for my dohc rs. seems to hold up fine, not sure if itll hold up with a turbo. for the valves and springs just depends on how your gonna drive it and how many miles on the engine already. if you plan to keep it forever and drive the heck out of it might as well replace them. good luck with the build. hope it goes well

The OEM valvetrain is quite strong. If you up your oil pressure like I did you can spin it to 8000rpm no problem. I've got 15,000+ miles on my B6T head with insane abuse to it...last Friday night I twisted a chromemoly drive shaft in half at Natural Bridge Drag Strip....would have be a 6 second pass. I'd have stood the car straight up if it would have been rear wheel drive! Launched at 5000rpm, 5+psi of boost and it HOOKED (got er right finally).

Need any custom parts? We got your back....also, Corksport can help you with the ARP head studs and a Cometic HP MLS Head Gasket if you like. I've used both the Fel-Pro MLS & the Cometic and haven't had problems with either of them....the Cometic needs a smoother head n deck surface than the Fel-Pro and will leak oil a little bit if you don't dress those surfaces to the minimum RA (surface finish).

Thanx for the info guys. If it were not for this forum, I'd know jack.

6 seconds

I think that would have been a new MX-3 record. The best I've seen was a RWD conversion that did something like 7.9.

not yet....6's would be 1/8th mile for me and 10's in the 1/4 with All Season street tires. My eventual goal is atleast 9's flat in the 1/4 mile.

The car your talking about was Marcos Acosta's (I apploligize if misspelled). He was running a 20B turbo with nitrous, tube frame, and rear wheel drive...basically a MX-3 body style on a funny car chassis. If that counts as fastest MX-3 than Bob Norwood built the fastest Integra...runs 5's in the 1/4 mile, makes 4000+HP on a Nitro twin turbo 4.6L Aluminum inline 4cyl.

O, ok, 1/8th mile. Still getting close to the record though if you only include the stock engine series' (B6, BP, K8, KL). Wanna take a trip with it to speed world in Orlando and let me test drive it sometime?

We should seriously start a mx-3.com hall of fame for people like you, Dave, Steve (babybluemx3), and Rafi. Make a promo video with the hall of famers for mx-3.com

What piston/rod combo are you going to use in your rebuild? Standard bore? What Bearings? What about the block, any special treatment? Are you gonna have it balanced and blueprint? Who's gonna put it together?

Sorry about all the questions, I am just very interested in the steps people take in rebuilding their engines. Some do the whole shebang while others opt out on some of the fun(but unnecessary) things.

When I did my FE rebuild, I used all factory parts and gaskets. Standard bore and stroke 86x86mm. Didnt want to overbore if I didnt have to. I would have gone with some forgies but I felt that my power goals didnt call for them.

I do say that the next rebuild I do, my FE is going to get some good stuff.

No video's for me yet as the car hasn't run since I broke that custom axle...it also twisted up the V6 driver side axle splines and blew up the Mazdaspeed LSD all in about 30 feet.

As for this topic...The big 16G turbo is way over kill if you only want 200HP...it is capable of supporting nearly 400HP. The turbo you should be looking at is a small 16G or even the stock 14B if 200HP is all you want. A T3 super 60 or ultimately the Garrett GT25R would be the sickest choice for the ultimate response 200-300HP setup on your car with a .48 - .63 A/R turbine housing (7cm^2 for mitsu turbos).

P.S.

Just trying to get this thread back on its focus point.

As for engine building...keep your eyes open and watch for my post...might take a couple weeks...also hope it becomes a sticky and or copied to the FAQ's as this is one of the hottest topics for everyone and is repeatedly asked over and over.

When I make the post it will be tittled:

T3 Super 60 FTW!!!

As far as the big 16G, that was my first purchase. I don't believe I'll ever max out the turbo.. 380 hp is more than I want. But I figure that 200 hp would be a good starting point. I know that everyone gets the boost bug and wants more and more. I'm just giving myself a little head room from the get go.

a 16g on the ze or the 1.8l? i can get a 16g off my friends evo 9.....would it be worth it on the 2.5l? i can get it for cheap and throw in the tommy makinen titanium wheel and it would be sick......does the 16g bolt onto a t3/t4 flange is the question
