Please let me know how it's going with the Tomei's! gr Chrismo ([email protected])

Found it: CG motors have the same head & bore = 71.0mm CG13DE stroke = 80.5mm CG10DE stroke = 63.0mm & CR = 9.5:1 If you use the CG10DE pistons in the CG13DE CR becomes 80.5/[63.0/(9.5-1)]+1 =11.86 Only thing is.......they don't know if these pistons will hit the head in TDC! gr Chrismo

Ok, you say those 1.0 pistons will do the job? Leaving me at what ratio? I read a lot of people changed their cr, but what pistons do they use for this, and where can you get them? Also I'd like to know what pistons I should get to get my cr from 9.6:1 to somewhere around 10.5-11.5:1 I just...

Mail send... Hopefuly this will make the sun shine a bit more! gr Chris

Email is on it's way, thanks!

You tell me 50mm is to small? Even If I get cams no more than 256 duration?

The oem intake manifold on a CG13 engine looks extremely restrictive to me!! Before this car I had a Nissan P11 with the SR20 engine. This angine has a nice formed intake manifold. I had the idea making somthing like a SR20 intake on my CG13. Somebody showed me the custom intake Cisco has on...

Well I just looked and I never think this will fit! The 1.3 and 1.0 have a different stroke, 17.5mm more on a 1.3 I think the 1.0 pistons will pop out of the 1.3 engine TDC. gr Chris

I have a tb comming from a GA15 engine, and is 50mm bore. I'm thinking of getting out my oem tb, get the valve and maf sensor out, then make this one also 50mm. Whem done, place the spindle and valve from the GA15 tb inside my modified one. This should work fine! I cannot use the GA15 one...

It's like the manifold Cisco made.....the one looking like the inlet from a SR20. This way I think getting better responce and gain some torque! Also the oem tb is 45mm, this I'd like to change to 50. All together I'm convinced to get a safe nice engine. gr Chris

I placed a ad I like to look for Tomei cams on this site. I did get some info about those Poncams 256, and am pretty convinced that when raising the endcompr. a little bit, I'll get a nice and safe engine. If I'm wrong please do tell me so! I sure like somebody telling me this before, then I'll...

As they are realy hard, I'd say impossible, to get new from Tomei self, I hope to find some cams here! I had a deal on some Poncam 256 degrees Tomei cams, in and outlet for my Micra. I think those cams will run realy nice when raising the endcompression a little bit. As I place this post I...

Frank, Once the revs pick up you say. But at what revs do you feel power? From 1500 rpm, 2500 rpm? gr Chris

2mm off......wow, that's a lot man! Also 275 sounds like too much for me, but that's the problem: A lot of people tell me things to do (I don't meen you), but have NOT done it themselves! Like I tell them the sand on the Moon is green......how would I know, but if they believe me, then it's...

Also I forgot to ask: There is one option I'm thinking about..... If I take the 248 cams, and also change my compression ratio (now 9,6:1) to 10,5:1 , change the entire intakemanifold and modify the tb from 45 to 50mm. What would happen, and would I still have a SAFE engine with about 100 HP...

I've got a Nissan Micra K11 CG13DE from 2000. Already I have made a custom stainless exhaust header, and like to go and make a aluminium intake manifold as well! The next step for me was build in faster cams. I've looked around an found out the Tomei Poncam 256 degrees would be nice for me...
