Marcus' 4th Gen Accord ( H22A U2Q7 LSD Swapped)

[93 Accord]

So, with all that exhaust dominating both the power increase and sound, I thought it best If I balance it out with a intake manifold upgrade.

 

Accord Type R manifold (Euro R)

 

 

 

 

After researching I now have gathered all the bits required to do the conversion. 

 

 

I have the IACV adapter plate from Rosko Racing ordered.

 

I have a thermal intake manifold gasket which apart from the heat reduction, spaces out the manifold away from the head to save grinding off some flange.

 

Grub screws to fill the little air injection holes on the flange.

 

2 meters of 4mm ID silicon hose

 

Pack of vacuum pipe connectors spitters and reducers.

 

Tube of Hondabond.

 

So far Ive stripped it down, and cleaned up the manifold, and ported out the first runner (still needs smoothing) 

Turned the brake booster fitting 90deg so it points to the left hand side of the car. My brake booster pipe is a off centre U shape. Simply reverse fitting this pipe make it fit on the manifold just right. I also have cleaned out the EGR system.

 

 

Left one ported, right one not done.

 

 

Other things to note, are no real discussing anywhere into how to reattach all the vacuum lines onto the ATR manifold. The stock H22a has 6 small and 3 larger ones. The ATR one has only 2 small ports. This is where some rerouting and splitting will occur.

 

Also to confirm, Stock H22a manifold outside throttle body diameter is 62mm and the stock H22a7 manifold outside diameter is 65.5mm (looks very much like 66mm though)

 

Anyway more to come!

Nice work! Look forward to seeing more progress on the intake manifold!

[93 Accord]

So the little custom work on the manifold is done now, tapped and installed threadlocked grub screws, and capped of the big one on the bottom. All injector ports are now now ported out.

I bought a Honda p13 gasket to get correct measurements for this. I used it unopened so I can return it now, since the thermal intake gasket I ordered has finally arrived.

 

 

Now for the removal of the old one and the install. I am still awaiting the IACV adapter from Rosko, but that doesnt stop installation at least.

Building the manifold up and test fit.

 

Rosko Racing IACV adapter, hondabonded and mounted

 

P13 throttle position sensor and vacuum line extension.

 

ATR specific loom plug obtained to fit ATR air temp sensor. (Euro R guys dont need to worry about this bit) Still 2 wire and just slightly extended this from the CB loom.

 

Manifold flange close fit to the P13 head! This is no grinding of the flange and a Thermotec gasket. This is fully tightened up and it just interference fits agains the fin there. Easy solution if worried about it is filling the fin. 

 

Test fit, ready to attach stuff.

 

Things to do now:

Fit fuel rail adapter from RoskoRacing

Fit fuel rail and new orings

Attach brake booster pipe

Attach vacuum lines

Attach coolant lines to IACV

Fit throttle cable and bracket

loom tape the extended wires

 

Also I would like to point out that I am trying to fit this and retain all of the stock functions. So all of the vacuum lines from the black box, EGR, cruise etc. Keeping stock injectors and rail and IACV. Only things I am changing on purpose is adding an oil catch tank, and bypassing the coolant lines to the throttle body.

Really nice work there!

Well big update time, only been in the paintshop queue for like 3 months but, back in March I booked in for new rear arches. 

Last week I got it back, and I very happy with the outcome  This was done by a place called Reflex Auto Design in Daventry.

Progress pics from the paintshop

Finished product

Filled the antenna hole while I was at it.

Also got these radius rod bushes in too.

And did some serious tiding up inside all arches also.

Put on some new rear tyres, Goddyear Eagle F1 Asymmetric 3 215/45/17 91Y XL too, loving them also.

So yeah these arches were letting the side down Sorry had too. Really has freshened up the appearance.

Excellent.

Would it be rude to ask how much it set you back? 

[93 Accord]

I got quotes as low as £800 from other places. But in the end as this is a keeper i wanted it to last. They are quite expensive, they are used to doing much higher calibre cars than the Accord lol. They have prefect customer service, hard to find from bodyshops from my experience. They also used the old school lead fill method which is more durable but more costly to do than just filler. Anyway final figure was £1250.

[dr_broon]

Yeah, that's not bad for a proper job like that. Cheers

Another trip to the Nurburgring this year!

This time with some semi slicks up front, decent brakes and the U2Q7 gears and LSD.

Pics to come, but I manage to go pro both a lap on the Nurburgring, and the Nurburgring GP Circuit.

Here is the GP Circuit. Go pro didnt record til half way through the session, I was about 10mins in by this point. Please be kind, I had to google the track layout whilst in the queue to go out

Also the Ring lap, I did 5 over a space of a couple of days, it opens for public  use 5.15pm-7.15pm so normally a chaotic frenzy of people trying to get on. Again excuse the lifting of throttle, I am not a master of the ring!
