Nuformz makes a "Block Guard" for Honda "B" series open deck blocks running turbo kits: . Perhaps there is something like this for the EJ20?

1.84 liters, stock internals, stock cams, port and polish, T3/4 turbo, race fuel, TEC-2, cool plugs with a big gap (1.4mm?), lots of timing advance, 750cc injectors and 25 PSI =

 

Soren,

Looking at the power graph you put up, that Tec-2 needs a serious remap...... Must be like driving a "helter skelter"....

The peaks look good though,

Mark.

 

hello all!

I've just bought this 2.5litre kit. I should have the engine in about 1 month or so. I already have the HKS/Garret turbo (torque developments) the HKS frontmounted intercooler and GEMS ecu. When i used it on the 2litre engine it had a poweroutput of 327PK and 465NM of torque.

at what boost level did you get that power ?

 

Soren, that mod is to lower the compression, they do this because the Hondas are hard to get low compression pistons for, most people are after high compression for racing etc.

What I am saying is you don't need that mod on an EJ20, because you can get a good range of low compression pistons for the Sub's.

Soren,

It's highly unlikely to be the injectors. At low rev's the engine only uses a fraction of the fuel needed at high rev's, and that area looks fine.

To me, it looks like massive overboost cut, and I'd either check the datalog, or datalog some runs to see what's happening.

When I say a "mapping issue", I mean the boost control parmeters, more so than fuel, or ignition.

Mark.

 

R19KET,

Not my car... as I understand it, the big dip is due to a fueling problem, not a mapping issue. Ric is looking at getting even bigger injectors.

submannz,

The block guard is drifted into the open deck of the B16/B18. "Closing" it at the top to prevent to bores from moving (notice the water passages). It doesn't go on top of the block to decrease compression.

Before Fitting:

Head gasket in place (you can see the water passages:

hello,

I was running 1.25 bar of pressure at that time!

 

Sorry I have been away for a while, so haven't been able to post.

 

Stick, I am running a TD-05 turbo hybrid, with custom made impellas, with different inlet and exhaust housings. To give you an indication I can fit a standard TD05 inlet inside my new one. The BPM stroker kits are good for 400+ Hp there are a number of cars in Australisia running them.

Soren, that is a great idea looks good.

AJ,

Since you've seen the car (it's the first I've heard about it), can you tell us about it. I'm interested to know just what needs to be done, to get 400bhp @1.3bar.

I just had a look at the RCD site, but either I missed it, or it isn't mentioned.

The turbo must be pretty big (what is it), is it very laggy. What else have they had to do.

Mark.

 

Why not start with a car that can take 400bhp in the first place... for the money your gonna spend isnt a Skyline a better bet???

Jza

 

Excuse my ignorance but waht does it mean to have a closed deck block ?
Doesn't the RA have a closed deck block ?

 

jza.

You can spend 10k on a scoob and get it to run 500bhp.

10k ontop of the car will not buy you a 500bhp skyline. but then the skyline would need nearer 700bhp to offer the same performance!

 

what's an EJ20? and for that matter, what's CG8? sorry for such lame questions?

 

.

[Edited by alanjack - 7/28/2003 6:08:57 PM]

 

Std turbo and injectors giving 400hp then?

Hmmm.

Can smell something but will have to give them the benefit of the doubt I guess

 

Hmm...I'm running 12:1 and my 440's are touching the 90% region @ 6500 rpm...and I'm nowhere near 400 break...morelike 300 tops.

I'm smelling summat weird...could be shaggy here though.

You will need at least minimum of 550cc injectors to get 400+HP, and an uprated fuel pump without melting pistons all over the place.

400+ HP should be getting mid 10 second quarter miles if not, they are full of crap.

No not all RA engines had closed deck blocks, but basically ALL 1989 N/A and RS EJ20 motors did have closed deck blocks. Have a look on my web site http://www.geocities.com/subman2001nz/

RC Engineering has a page for calculating your injector needs:

I have a 2.2litre (open deck) legacy block (EJ22) that could be for sale at a very attractive price if anyone were interested.

 

Moray,

As a moderator I would've expected you to know the correct forum for something for sale

 

Sorry craig, it seemed relevant to this forum at the time, which doesn't alter the fact that I did my run 2 up.
