That says nothing for why oil pump gears fail, or that yours failed under what conditions, or what improvement you have measured with a different oil pump. This forum is supposed to be no BS, actual data, actual experience, not hearsay.

The ones I've personally seen, we revved to 7 grand just like stock, and after the car got to 240whp they just exploded. No signs or clues that they'll go

so after that I hopped on the "bandwagon"

this was a spirited driven street car too. I dunno

This is why my revlimit is 7000. No need to risk it. If I were racing and rebuilding my motor once a week things would change.

I'm on the bandwagon of "i want my motor to live > laptimes" you may be on a different bandwagon.

I stop making power after around 7350rpm. And my engine is built for over 8k rpms.
So it's useless except for rev matching and decelerating.

aidandj 10-08-2015 06:48 PM

Or skipping a gear change on the track.

Erat 10-08-2015 06:50 PM

Oh I've money shifted back into 2nd twice now. I'm positive it spun way past 9000 when I did it.
Nothing broke yet.

ok mister 18psi ,.
i have my reasons for using a 1.6. i don't care if you like them.
1. California
2. 1.6 weigh less not much but they do. so the weight is further back.
3. i don't like running a oil feed line from the other side of the world
4. same motor the car came with. kinda nice.
5. easily within my power goals


cams not on the list for a reason at the time of engine build. ran out of money
we decided it was the easy thing to change later. will change them with the new turbo setup

3. i don't like running a oil feed line from the other side of the world A 94-95 block would do the same
4. same motor the car came with. kinda nice. I mean its nice if you want to keep a shitty motor
5. easily within my power goals easier to make less for more on a 1.8

Reasons are silly :)

RedFox 10-08-2015 07:07 PM

your just sad someone likes the 1.6 better. and that you still have a td04

i have a extra t28r ball if you want

aidandj 10-08-2015 07:09 PM

I have a 1.6. I don't like it. The lack of torque is quite annoying. And I put the TD04 on recently. I kind of like it. It cost $50 bucks and should be good for a bit more power when I build the VVT motor I have.

Erat 10-08-2015 07:13 PM

If I build another DIY system i will use a TD04 again. Fantastic cheap turbo.

you do know the difference is only about 10% hp and torque?
and almost no one can really tell. the difference is actually not much. after a build and the turbo yes . but with the 6 speed it really becomes negligible

aidandj 10-08-2015 07:18 PM

I've ridden in both. 1.8's have quite a significant increase in torque, and seat of the pants feeling. They spool a good couple hundred RPM's sooner. Add VVT and you have another 500rpm of spool.

I have a 6 speed. I don't see your point.

I see a 50ft/lb difference until the boost difference comes in and power goes up.

You must be pretty damn un-observant to not notice 50ft/lbs.

ah you are silly i said 10% referring to stock...
but after turbo and build i agree

aidandj 10-08-2015 07:31 PM

Where the fuck in this thread have we discussed stock engines?

can we not fight over STUPID STUFF please....
it really doesn't matter that much .
you are right about the 1.8 being better power wise.
spool because of more displacement ..

18psi 10-08-2015 07:34 PM

sure. stop posting stupid stuff :)

I mean you're on stock pump and stock cams. What is there to discuss?

RedFox 10-08-2015 07:41 PM

i kept the motor because my now passed away girlfriend of 5 years helped me pay for the car and some of the motor parts ... I don't have a better reason. and i don't think any of you do... so this is my forever car/motor.
i came here for multiple opinions. not to be judged because of motor size all 150 cc of it
