Anyone want 65+ more hp for their 1.6 SOHC NA?

Josh - I took a look at the pics you have up of your engine. I have to admit it is one of the prettiest things I have ever seen (next to my wife and two daughters of coarse). I hope mine will look as nice when I am done. I have updated my MX3 project plans on my website if anyone is interested. My MX3 project

Also do you know if the G series tranny will bolt up to the 1.6 SOHC, CLutch, and Flywhee if I replaced the other parts you mentioned above.
THanks for the info.

thanks

yah the g series should iv heard roumers that you might have to change the bell housing. if i were you, call up Corksport and ask for Derek hes the man that would know for absolutly 100 percent. you can still use your flywheel and clutch, unless you want to swap it up for a bigger one which you will find on any 1.8L.

I can speak with experience about Gude, and their shoddy work and bullcrap claims. A couple guys on the Escort GT board bought the full gude package including cams, ported head w/5-angle valve job, polished & decked and a ported intake manifold & big bore throttle body. They dyno'ed 18 whp over stock. Gude claimed 50whp. Total BS.

On a 1.6 SOHC you'd be lucky to squeeze an additional 15whp out of that motor. The best way to do it is to buy a camshaft, and I/H/E setup. Crankpulley isn't going to do jack squat so don't waste your money.

For all the money you'd spend, you could've taken some auto mechanic classes, and learned how to swap out your engine. On top of that, you could've bought 5 BP engines seeing how they are as cheap as 150 dollars (yes, for a good one) if you look hard enough.

THere is a couple things that some of you are not thinking about. Much of the money I am spending is money that would need to be spent on any engine I put in this car (Exhaust, cold air, ported heads etc.) So buying another engine and swaping it would be additional $$ to what I am already spending. Granted, it would give me a higher starting point for gain.

Thnkyou for the info on Gude. You are not the only one to tell me that. Today I put the breaks on the work that I was having done there. And at the risk of sounding like John Kerry, I have changed my mind on continuing with this 1.6 SOHC project.

My good friend who is a Volvo mach. told me that since I have to pull the engine out anyway for the rebuild, I might as well put in the 1.8 SOHC from the protege DX back in. Same wiring and everything. THen I will be starting with almost 105 hp instead of almost 90. I found a 1.8 SOHC near me and I am going to rebuild it with oversized, 10 to 1 comp pistons- etc. And send the heads off to importperformanceparts.net (instead of Gude) for porting, vaulve work, cams, etc. With the exhaust, pulley and cold air intake I already have on the car I should get much closer to my goal.

Thanks for all the input here. I spent a couple nights tossing and turning about this, and I have lost some money, but I think this will be a better project. (now I need to update my website again).
P.S. do't tell me I might as well put in a bp DOHC while I am at it. Unless you want to come to St. Louis and do the wiring for me, and I do not have time to take any classes either.

[papa roached]

im gonna say it anyway

the 1.8 DOHC BP swap is not different than teh 1.8 SOHC swap other than 2 wires to control the VICS, and that should be pretty simple to setup or just tie the VICS open, you will lose some in the bottom but you will still have the top end

[rukick]

I told you not to tell me that. LOL
I was told that the bp DOHC totally falls on its face without the VICS.

if they are closed you will have bottom and crap top end, with em open you wont have alot of bottom power (not less than the 1.6 SOHC) but plenty in the top of the tach, i say but the DOHC in and wait till a later time to wire up the VICS

just to let you know, you said that you were going to put in oversized pistons. go to flyin miata. they now have an overbore kit to bore it to a 2.0L. yah a 2.0. nice. you can get 8:1 or 10:1 i beleve, and they come with forged rodes and a steel billet crank. a little spendy, but if i were going to start all over again it would be a 1.8 into a 2.0. alot more displacement over a 1.6. good luck

[BuGS]

Josh is right. That kit sounds awesome. And the DOHC BP gives you even more base HP. So i would probably go with that then just run the extra 2 wires to the ECU you need to. Wouldn't be too hard.

[rukick]

I had a long talk with the tech guy at importperformance.com. He was very helpful. He told me that they could make that 1.8 into a 2.0L engine too with custom forged 10:1 comp pistons. He wanted me to send them the block with crank and rods and they will bore it out and put sleeves into the cyl. to reinforce them. He also said that they will do stage 2 performance head work (ports, valves, etc). All of this plus all the rest of the parts for a performance rebuild for around $2700.00. Does anyone know about big bore sleeving or has anyone dealt with importperfomance.com before?

[Josh]

its way better to re sleve when your boring your engine. are they going to use your stock rods? they would probably be fine but carillo H beem rods are like half the weight. just makes for better revs. but all in all sounds like a good deal as long as they do the work rite. let us know how it turns out.

[rukick]

I will let you know but it will be awhile. He said 3-4 months after I ship the parts to them. And I still have not picked up the new engine yet. Also I got the web address wrong above. It is www.importperformanceparts.net

[BuGS]

ya let me know how that turns out. Sounds good. Also you are doing this with a BP engine right??

[rukick]

I think I am going to stick with the SOHC 1.8 from the protege DX. If I go with the bp DOHC I am going to shred my tranny. I want to stick with the f series tranny so that I do not have to get a new clutch and flywheel. Plus I just really do not want to try to mess with the wiring. I know there are other guys who have done the DOHC swap awhile ago and still do not have the VICS figured out yet.

[atlantamx3]

Man, Honestly-- Dollar for dollar-- the DOHC BP is better and has more aftermarket support then the SOHC BP.

And, if you are going to go thru the hassle of doing an engine swap-- just get the DOHC.

You can keep your F-Series tranny with NO problems.

You may want to get a Protege LX Wiring harness like I did-- it fits right in and only takes 30 minutes - 1 hour to pull the old one and install the new one (especially with the engine out). All the sensors will bolt right up and it will plug straight in if you get the BP10 ECU (Protege LX).

The DOHC BP swap into a SOHC MX-3 is so straight-forward that it makes the Honda swaps look like Brain surgery.

All the mounts are the same and the harnesses plug and play.

You will laugh at the ease of this swap if you can find a Protege LX Wiring harness and a DOHC BP.

The extra HP is worth it-- so like I said earlier, if you are going to go thru the hassle of an engine swap-- get the bigger one! (and-- you can use stuff from the Miata!)

[Shady469]

i can tell you from experience the f-series tranny is crap. i've busted 2 not even really abusing them. go with the g-series; the gearing is awesome for racing and it can hold alot more power.
if i were you i'd go with the BP... there is no replacement for displacement(besides lots and lots of boost! ) and if you look there are some fast BP mx-3 with not a whole lot done...
If your gonna go all out do it right...
