Reality check!
 

Damn man i have searched everywhere for some good perfomance mods but it seems they don't make dick for SOHC why is that.If anyone(REALITY) knows where or even if they make some of these things plz let me know.

Underdrive pulley for crank and alternator,cam,headers,bigger throttle body.
and light flywheel

Also will this work and is it worth the money: shaved and buffed head.I dynoed at the votech last week and 117 whp isnt cutting it .PLEASE HELP and one more thing if I went turbo how much am I looking at where would I get it.

For the most part, when it comes to engine performance parts, it's slim pickings for the SOHC. No one makes a header for the SOHC. I think that Bullfrog makes a bigger throttle bodies for our car, but not quite certain. I do happen to have an unorthodox racing underdrive crank pulley on my car. It is a crossover part from the 91-93 Miata 1.6 liter car, which shares the same block as our cars.

Thanks
 

Does the underdrive pulley make you feel the difference?And I was wondering if I had the a/c completely removed how much would that help.

sohc dyno'd at 117whp? whut kinda sohc do u have. last time i checked its rated at 103HP at the flywheel

When I said the same....I meant the same "design" based on what I've read and based on the fact that Unorthodox Racing told me they were similar enough that 1.6 crank pulleywould bolt on no probs (the 1.8l is 22mm longer than the 1.6.) The fact is it was an excellent fit...just as if it were factory.

"In 1994 the need to meet emissions standards and to confront cries for more power in the Miata was answered by using the 1.8 DOHC motor that has been in the Protege since 1990. It is also a ‘B’ family member but has a longer bore spacing to accommodate the larger 83mm pistons. The stroke was also increased to 85mm (both the 1.6 and 1.8 DOHC have the same 221.5mm block deck height and 134mm head height). The 1.8 is the same design and is just as robust as the 1.6. It has the same rods, same oil-cooled pistons, same oil passages, same head design, same HLA's and same crank design. Unlike the 1.6, the auto trans version of the 1.8 was not changed at all.

Since the 1.8 is really just a stretched 1.6, most everything on the front and back of the motor will interchange between the them. This includes the cam angle sensor, coolant intake pipes, flywheel/clutch assembly, various covers and brackets, cam gears, water pump, and timing belt tensioner, etc. The intake manifold, exhaust manifold, motor mount brackets and camshafts do not interchange because of the bore spacing differences. The 1.8 ‘B’ motor has also seen duty in the 1991-1995 Ford Escort GT/LXE, 1990-99 Mazda Protege, 1991-95 Mercury Tracer LTS and Kia Sephia GS. (FYI, the 90-93 Escort GT and Tracer LTS 1.8 DOHC use the same throttlebody and flowmeter as the 1.6 Miata). "

Just thought I'd mention that with the UR pulley, there was a slight improvement in midrange acceleration. I have an auto, so it will probably equate to a tenth or two in the quarter. I'll have more quantifiable figures when the local track opens again. I do plan on buying a shorter belt to bypass the compressor since my AC is currently AWOL.

This miata guy swapped the 1.6l for the 1.8l. He notes exactly what I said about the pulley. It's a perfect fit.

The crank pulley designs were changed in late 1991. The later design uses four bolts to hold the pulley onto a crank adapter ring. This design was carried forward though 3/1995 so the late 91-93 1.6 pulley will bolt to the 1.8 adapter ring. If you decide to go with the Unorthodox underdrive pulley you'll get the version that doesn't use the adapter ring. You just simply slip it directly onto the crank. My Unorthodox pulley installation pictures are linked from my Recipe for HP page on the 'street motor' page.

What about putting on a Dohc head and turbo charging it ??...Jon

The SOHC engine may actually have more potential for turbo as it has lower compression pistons. If we get enough people a turbo manifold for the SOHC would be $450 iirc.

450?
 

I'm in I'm good for that money.Lets hope we can get enuff people just make sure I know if it ever goes down.OK

True. I just mean to say that there is still plenty of performance potential in the SOHC too :)

And I think that I read you need to change the engine mounts along with the tranny, if you want to swap them? Why is this? :shrug: (I know you need to change the axles too)

Note Jesse KNOWS EVERYTHING. so mike dont try to fight with him

LMAO:D

What about the Fwd GTx transmission? how strong are those?....jon

what FWD GTX?

quick question
 

If you had the money and wanted to make the fastest gen 1 protege what would you do (ESPECIALLY TO JESSE)

I figured Jesse just misread the post...I was simply clarifying things. Besides, the only fighting I do is pillow fighting with the ladies on the weekend. And to think it's all cause I have a hot 1G!! Life is good.

Well prob not with the name GTX but i know they have a FWD transmission on bpt's over seas with a Lsd in it, Maybe they call it a GTI? something along those lines, Anyone ever use this? ...Jon
