When it was cold it just seemed down on power, obviously it got worse as it got hotter. The temp that day was fine, lower than usual. I do usually run the car with the heater blasting though since...

It definity felt like a timing issue at the track. And yes, it ran worse as it got hotter and started to detonate more. It will be a few weeks before I can get the car out again but I will follow...

Before the last race I put a fresh head on the car. Nothing unusual, just cleaned up, port matched and new seals. It was not plained. New plugs, wires, cap, etc at the same time.

At the track...

For the bargain basement version....

I am running the stock tear drop style wheels with 3/4" spacer. I would like a little bit more but don't want to put more stress on the studs.

I replaced...

I think there are 2 sensors, 1 for the guage and one for the ecu. The engine did not seem to be affected by the heat.

I do have an autometer guage sitting on the shelf that I have been meaning to...

First time out with the new head on was this weekend. The car seems to be struggling for are above 5400rpm and would barely climb to the stock rev limiter in 3rd. I played with the distributer...

I welded the diff in my 240sx. This was by far the best modification I have made to the car for any money and the best part is that it was free and easy. I willl admit to having no experience with...

Just a newly aquired parts car (bought for the transmission) but it worked great when I brought it home so I knew the ecu was good.

Turns out #2 injector was firing almost contantly and the rest...

A new ecu from a known good source and all is well with the world again.

Not sure what a Cold start injector is. More details?


Jim, I can't remeber when I did the compression check since I have gone through this thing so many times now. I will do it again and report...

I really need some advice on getting my car up and running again. I swaped the head on what was a perfectly running car and now have a car that barely runs. I have about 50 hours into trying to...

Thanks for the replies so far.

How much can I/ should I take og the head/block? And is an offset cam gear required or legal?

I have not check the compression of what I have. It is easy to do though so I'll try and report back. Is there a way to tell which pistons my motor has? It is a bone yard special so I'm not sure...

I drive an ITA240 and my obvious competition is the CRX.

I finally have the car to a point where I am very happy with how it handles and brakes but I am getting toasted on the straights.
Luckily...

Most of mine move freely and definitly move more than 1mm so I guess they have air in them. Hopefully they will work themselves out on the car.

Some however, do not move at all. Ususally I can...

Can you take them apart to clean them? do you just pull the insert out?

Is it harmful to let the car run while they are tapping?

I'm about to re-install a head that I had freshened up. It had previously been sitting, disasembled for years.

I soaked the lifters in clean oil for a week or so but some do not want to move and...

Just got the head back from the machine shop. They did a valve job and replaced the seals, tested the springs and presure tested the head. They did not take anything off the head as they said it was...

I just got mine from PDM racing in BC. I have not yet installed it though so I can't really help with the other questions.

I am planning on running a cooler and a second filter.

bilracer, I would like to take you up on that offer if the diff is out of a 240. I currently run a welded open diff which I am very happy with for the price ($0) but I would like to take the car to...

Thanks for the helpful suggestions.
I'll dissemble what I have and send it to the machince shop and see whay they say.

I'm just going to work on the top end for now since I have a spare head. I didn't know I was allowed to work on the valve seat. guess I'll have to go back and read that part again.

As far as...

I have an extra motor with a toasted bottom end but the top is fine. I figured since my race motor is a bone-yard piece it may be wise to rebuild at least the head of my spare motor. It will also...

Can you distinguish between the 2 styles of pistons by looking at them? Do the "flat-top" pistons simple have a flat top and the regular ones valve reliefs?

Can someone post a pic if they have...

Picked up Ken's old car from vantage last night for the cage. Should make a nice safe winter beater right?

I'd loose my shirt if I sold the 240 so I can't see me racing a golf anytime soon. I...
