The old one did a dyno test and it was worth 10 hp on a mildly boosted engine with everything held constant. I have a boosted B16 and did GSR cams, it hits hard at switch over, I set my cross over at full spool 4500 rpm, for me it was worth the 50 bucks.

I would suggest not to use the T25 turbo, it does spool very fast but will run out of air on the top end fast, make sure you correctly match your engine to turbo size for what you want to do.

If you don't want it a dog off of boost you could do what I did. I took a B16A, under drive pulleys, puck clutch, Alum flywheel, bored and ported manifolds, and throttle body, ported head with GSR cams, ARP head bolts and added a T3/T4 turbo 57 trim I chipped and using a wide band I tuned it to...

Have you done the basics? I had the same issue and it was the cap and rotor. I have also seen issues with vacuum leaks causing missing, ie the hoses to the map. (this does not raise the idle) Spark plug wires arcing to ground will also do it.

Not a problem...good luck with getting it going...

You really need to do some research. It does not matter what size injectors you run, as long as they are large enough. Currently I am running 880's for my street car. When you get into the larger injectors you will hear peak and hold or saturated injectors, the difference is the resistance of...

I only run NGK, for me they work I'm sure there are other choices but they are cheap and they work well. If you are not running a hot coil gap at 28 thousands.

If you are running a ebay turbo you will need to run an oil restrictor type of turbo oil inlet flange.on the supply side. The other choice is to use a -3 oil line which will restrict the oil flow enough to solve the problem most of the time.

I guess he means that the clutch was slipping. Depending on how much you adjusted it I think you might be needing a clutch real soon if it starts slipping at crossover of vtec. It must be that extra 5 ft/lbs of torque making it slip...

B16 racer is correct, use a 90-91 teg clutch and flywheel if you have a B16 cable trans. I also am running the XTD clutch but the stage III setup, no problems with it running a turbo B16.

eBay turbos I have built 4 turbo honda's with ebay turbos. I sourced all the parts on ebay, don't buy a kit, do your research and buy the components. I only use cast manifolds due to durability. As to the turbo's I have not had any issues with the turbo's other then having to use oil restictors...

I started with a 91 civic si and used the si harness on the B engine I swapped in. The injectors leads where short but I got it to fit. for ease I ordered the knock and vtec harness from Rywire also.

If you chip the pm6 it will run any of the OBD0 engines as in ZC or D series, As to engine any D series non vtec is your cheapest choice, with add on's 120 hp, if you want to upgrade to a vtec a single cam will be the second choice for ease and cost you can do a one wire and keep obd0 with...

If you are running the hot side on the drivers side the compressor will hit the trans bell housing, I wanted to run mine that way so I used a log manifold kit and used the exhaust flange as a spacer with longer exhaust studs. I am running a cast manifold and compared a couple, they all had the...

Good planning as to "starter turbo" and such. Something to think about also is the mounting flange, if you run a T25 you will need another manifold when you are ready to upgrade, if you use a T3 you will have a lot more options for turbo's that is. How I look at it now is if possible I try to...

Pissedoffsol, I should have been more careful in how I phrased my comment, the larger turbo due to its larger size and "pumping efficiency" will be more effective in moving air then the smaller turbo. I will know that this issue is a dead horse as in topic so I was giving a short answer.

Posting is adding "posts" they are screws that are made out of the same material as the block and screwed into the block and help hold the liner in place limiting distortion as the engine runs. Sleeving is the liner that the pistons run in, as in resleeving....

I'm not trying to flame you about the turbo, but with you goal of 250 whp I think you will have difficulty meeting your goal with that small of a turbo. The turbo will be off the compressor map prior to max torque, and out of air on the top end, but it will spool right off of idle so thats in...

For the money you spent on that why did you not just get an ebay turbo? even if the turbo is a POS and will only last a year you could at least match it correctly to your engine. A T25 is just about large enough for my lawn mower. Yes you can over boost them to 10 psi but the eff drops way off...

Turbo's when you shut them down coke, which is the oil burning due to no flow, water cooling helps control the over temp issue and adds life.
