Running premium gas. 93 octane in Chicago area. Up here in MN, I have only found 92 which should still be okay. As soon as I find a station with 93, they will be getting a lot of business from me.Car went back to mechanic to get checked up on and to figure out the binding issue with the new steering rack. Have not heard anything yet.

Iam going to assume that you didnt do this, but may ask anyways.

Did you happen to get a flow test before and after the p&p to see the change? What about a valve job? yay or nay. I think you should pick up quite abit of power for the cams and p&p, cant wait to see a dyno.

Apparently the steering arm was hitting the header.We don't know the brand name of the header (it looks like the same design as the Hot Shot, but it is stainless steel). My mechanic picked it up from a friend of his (a distributor- not just a friend selling used parts) who thought it was some japanese aftermarket part, which doesn't make a whole lot of sense. Whatever, its pretty...I still don't know about the flow-bench test.I'm scheduled to pick it up (for the 4th time or so...the difference is it has actually been driven this time) Feb 25.

as this build shows...thank god for daily drivers
The blue car by mine is indeed a spec Miata. Apparently my mechanic has built 12 in the past 2 years.

Still Have not go numbers yet???? Well I bet your anxious. any ways did you ever get a one peice aluminum drive shaft? If you didnt you should see the diffrence with a before and after dyno. anyways havent kept up with this thread but I will now. Good luck on your numbers and all the last minute fixes. Make sure you take it out drifting. Its great to build numbers but more fun to drift with them!!!

I still haven't even driven the car yet!I'll be picking it up from my dad Feb 25 or so- we didn't want to go highway driving before 1000 miles.I couldn't afford a driveshaft at this time, but I'll be saving money for that and a quaife diff to put in next year.

You only need to break in the engine for the first 500miles.

Most people break in their cars pretty wrong, as well. The highway is actually one of the best places to drive it during break in as you WANT to put a fair amount of load on the engine (but at low RPMs) and low RPMs in 5th is the easiest way to do it.

Ageed, just as stop and go street driving is the worst way to circulate oil through the engine as well. Some people learn the hard way though.....

If I ever go SR, I have the perfect route in mind. US287 between Ft Worth and San Antonio. That should break in nicely, just have to have a friend behind me just in case.

US287 is a highway that runs parallel to I-35, but since almost everyone takes the interstate it is mostly unused except by locals. I remember driving on it one time on a Sunday. I would crest a hill, could see for miles, and only be able to spot 2 or 3 cars tops ahead of me.

But a 6 hour long drive along I-90 away from my mechanic is not exactly the best way to get through the first 500 miles. You didn't know the exact situation, I didn't describe it thoroughly either.My dad drives a good mix of non-interstate hwy about 30 miles roundtrip to work. Its got about 400 miles on it at this point and things are looking pretty good.

You didn't know the exact situation, I didn't describe it thoroughly either.[/quote]No offense but what does driving away from your mechanic have anything todo with it. If it breaks down due to engine failure within the first 500 miles you shouldn't even bring it back to this mechanic.

You need to rape your engine hardcore seriously. Do some engine breaking where you bring the rpms up and let go of gas and leave it in gear and let it slow its self down. Due this with a conservative rpm then after awhile bring it up another 1000 rpms and do the same thing, keep repeating till you get to a good rpm. This engine breaking thoery causes allot of vacumn in the cylinder which cause the rings to push out extremely hard against the cylinder walls.This does about 80% of the breaking in BEFORE the first 500 miles. The last 20% takes forever to do since the honing grooves are now just about rubbed smooth. So if you don't break in the rings before the honing marks smooth out its gonna take forever for your rings to seal really well that if they EVER do. tsk tsk

Whatever.I just got cast in a show that opens in 2 weeks. I won't be picking up the car until late march. Yet another setback, but this one is worth it.

OMG! WTF! Waste of lunch? Naw, this thread is entertaining. Where are the numbers!!!! Does anybody have a gauranteed recipe for 200whp with a ka24de in an s14 that will pass smog on pump 91? Just asking. Thought maybe Ajax' numbers would answer for me. Oh, and Ajax, what's the ballpark $$ you spent on this project and what did you get?

Numbers will hopefully come by the end of this month.Ballpark was more than you'd spend for an sr20 (difficult to say as there were a lot of other things that were rebuilt or replaced- non-engine), and I got hosed. Seriously- 2 years later and I'm still dealing with drivability issues.If I knew then what I know now, I would have saved the money, amassed parts myself and let DJpants build a spare motor while I drove the old one to the ground.Its still a fun car, don't get me wrong, and it is stronger than it was before, but the mechanic I used utterly failed me.For anyone in the NW Chicago area- they may work on lots of expensive exotics, but Automekanika sucks balls.

After reading this entire thread . . . I believe I will go buy a junkyard motor and rebuild it myself. I'm already on my third engine, third transmission, and second clutch (the clutch broke when my last transmission locked up). It will probably be a lot cheaper, plus it won't take my DD out of commission just as long as the engine I have in it now doesn't blow. I guess I need to quit racing it at the track. I have no internals done, just the intake, exhaust, and ignition so far. I run 93octane and I have a lot of fun driving mine even though it has around 184k on the car. Once I buy another car to replace it as a daily driver, the car will be gutted and heavier mod's will be applied. But Ajax, I commend your patience on this matter because if it had been me, I would have had the car taken somewhere else. But it's Thurday night and its time for me to go drinking with some friends and get some love from the ladies

Unfortunately, taking the car somewhere else was not an option as the mechanic is by my parents while I'm far away in Minnesota... but thanks.
